What are SMD bulbs? SMD vs DIP LEDs

LED? DIP? SMD? E-I-E-I-O?

Link to Moonleds

It's a farmyard of acronyms out there when it comes to LEDs and Christmas lights and hopefully, this article will shed a little light on what these terms mean as folks plan Christmas light displays.

Applying direct current to specific crystals to produce light was discovered in the early 's by a scientist at Marconi Labs. The technology was unavailable for widespread engineering application until the s and 70s when engineers working with semiconductor components and integrated circuits used the light generating qualities of these crystalline substrates to create light-emitting diodes (LEDs).

Think Star Trek and all the flashing lights on the computers. (Those were just normal light bulbs but hopefully, that visualization gives you an idea of why one would need tiny little lights to be part of electronic circuits and displays.)

Initially, LEDs were built in a Dual Inline Package (DIP) like the LED shown here.

The two pins were inserted through and soldered into integrated circuits. Initially priced at about $200 per component, these LED's were used primarily for high-end electronics.

Around , design advances and lower prices allowed LED lighting technology to make an appearance in LED Christmas light bulbs.

Over the years, LED Christmas bulbs have improved to be brighter, truer to color and continue to provide light at up to 90% more efficiently than traditional incandescent bulbs.

You can see a more comprehensive timeline of the development of LED lighting as Christmas lighting in our article: Christmas LED Lights: A brief historical overview

SMD: The latest LED innovation

Surface mount components are basically what the name says they are. Instead of two pins that poke through an integrated circuit board, this packaging was developed for flat installation on integrated circuit boards. This design innovation was a necessity as components grew smaller and engineers tried to cram more and more on a single board. These SMD LEDs delivered more light than their predecessors and were easier to install during automated manufacturing.

After achieving widespread use in commercial applications, engineers have now created a new style of Christmas lights based on this new LED format.

Advantages of SMD style LEDs:

• 20-30 percent brighter than DIP LED's - range based on color and visual perception of different colors
• dimmable - yes!!
• useful for animation
• tighter color range so kelvin specifications can be effectively measured

At Christmas Light Source, we're excited to offer many of our C7 and C9 LED bulbs with this "new to the Christmas light market" technology.

First-generation ( vintage) LED bulbs are still available in select colors. They've been reduced in price to move them out of the warehouse. Take advantage of the savings to add more bulbs to your Christmas display.

The bulbs

So, what does this really mean to me? (We know you may be asking yourself that.)

Here is a comparison photo of warm white C9 faceted bulbs.

Note that color has stayed constant. The internal light dispersion has also been improved.

Tips on adding SMD bulbs to your display

While the SMD bulbs are brighter, the colors of the bulbs have stayed consistent between and making mixing of bulbs reasonably straightforward though you may have to give the final installation a little bit of forethought.

Consider the following tips for installation:

• Randomize old and new stock to blend the two brightnesses/styles together (Is brightnesses really a word? Grammarly says it is!!)
• Install new style bulbs on the front of installation and move last generation bulbs to the sides and back of the building

And as always, we strongly suggest that all LED products - bulbs, strings and nets - be plugged into GFCI plugs and surge protectors to protect them from spikes on the line caused by things like hydroelectric power generation, geothermal, lightning strikes, transformer failures and more.

We're excited about this new style of LED bulbs and look forward to seeing photos of your Halloween and Christmas displays.

Have a Merry Christmas!

Dimmable LED technology refers to the capability of LED (Light-Emitting Diode) lighting products to adjust their brightness levels using a dimmer switch or a compatible dimming system. LEDs are semiconductor devices that emit light when an electrical current is passed through them. Unlike traditional incandescent or fluorescent lights, LEDs can be easily dimmed to create different lighting atmospheres and conserve energy.

Dimmable LED technology allows users to control the intensity of light output from an LED source. This is achieved by adjusting the amount of electrical current supplied to the LEDs. Dimming can be done manually using a dimmer switch, which is similar to a regular light switch but includes the ability to increase or decrease the brightness. Alternatively, dimming can be controlled through automation systems or smart home devices that provide more advanced features and programming options.

 

How Does Dimmable LED Work?

Dimmable LED lights work by regulating the amount of electrical current flowing through the LED chips to adjust the brightness level. LED chips are semiconductors that emit light when an electrical current passes through them. By controlling the current, the intensity of the emitted light can be varied, allowing for dimming capabilities.

There are primarily two methods used to dim LED lights:

• Pulse Width Modulation (PWM): PWM dimming is the most common method used for dimming LEDs. In this technique, the LED is rapidly turned on and off at a specific frequency. The ratio of on-time to off-time, known as the duty cycle, determines the perceived brightness. When the LED is turned on for a longer duration during each cycle, it appears brighter, and when it is turned on for a shorter duration, it appears dimmer. The high frequency at which the LED is switched on and off is usually not perceptible to the human eye. Pulse Width Modulation (PWM) is a preferred method for dimming LEDs, especially when maintaining a consistent colour temperature is important. The fast flickering process in PWM doesn't noticeably affect the colour quality of the light, ensuring that even when dimmed, the LED maintains its original colour temperature.

• Analog or Current Reduction Dimming: Analog dimming involves reducing the electrical current flowing through the LED to adjust its brightness. This can be achieved by using a variable resistor or a compatible dimmer switch. By reducing the current, the LED emits less light, resulting in dimming. Analog dimming is often used in conjunction with driver circuitry designed specifically for dimming applications.

What are the benefits of using dimmable LED Technology?

Using dimmable LED technology offers several benefits:

• Energy Efficiency: Dimming LED lights reduces energy consumption. By lowering the brightness level, less electrical power is required to produce the desired illumination. This results in energy savings and lower electricity bills. Dimming a light by 10% can potentially save up to 10% of energy.
• Extended Lifespan: Dimming can help prolong the lifespan of LED lights. LEDs are sensitive to heat, and by reducing the brightness, less heat is generated. Operating LEDs at lower power levels through dimming reduces stress on the components, resulting in less wear and tear and extended operational life.
• Flexibility and Mood Lighting: Dimmable LED lights provide flexibility in creating different lighting scenes and moods. Whether it's in a residential or commercial setting, dimming allows users to adjust the brightness according to their preference and the specific activity or atmosphere they desire. For example, dimming can create a relaxing and cozy ambiance in a living room or a more vibrant and energetic atmosphere in a party or event space.
• Visual Comfort: Adjusting the brightness of LED lights through dimming can enhance visual comfort. In some situations, full brightness may be too intense or cause glare, especially in areas where tasks requiring focused attention are performed. Dimming the lights can help reduce glare and eye strain, providing a more comfortable and visually pleasing environment.
• Customisation and Control: Dimmable LED technology provides users with greater control over their lighting. With compatible dimming systems or smart home automation, users can easily adjust the brightness levels and create pre-set lighting scenes for different activities or time of day. This level of customisation allows for a personalised lighting experience tailored to individual preferences and needs.

How do You Recognise Dimmable Led Technology?

To recognise whether an LED light is dimmable, you can follow these steps:

• Check the packaging or product specifications: Look for information on the packaging or product description that indicates whether the LED light is dimmable. Manufacturers often clearly label their products as dimmable or non-dimmable.
• Read the product manual or documentation: Review the user manual or any accompanying documentation provided by the manufacturer. This documentation should specify whether the LED light is dimmable and provide guidance on compatible dimming systems or switches.
• Look for dimming symbols or icons: Some LED lights may have specific symbols or icons printed on the packaging, bulb, or fixture to indicate dimmability. These symbols can vary, but common indicators include a lightbulb icon with a curved line or a symbol resembling a dimmer switch.

How does Dimmable LED Technology Impact Energy Consumption?

Dimmable LED technology can positively impact energy consumption in a few ways:

• Lower Energy Use at Dimmed Levels: When an LED light is dimmed, it uses less energy. For example, dimming an LED light to 50% brightness typically reduces the energy consumption by approximately the same amount.
• Extended Bulb Life: Dimming can also extend the life of the LED bulb. LEDs, unlike traditional light bulbs, don't burn out in the same way&#;they dim over time. By using dimmable LEDs and operating them at less than maximum output, you can extend the effective lifespan of the bulbs, meaning you'll need to replace them less frequently. This leads to less overall energy consumption in the manufacturing and disposal of the bulbs.
• Reduced Heat Output: LEDs are more efficient than incandescent and halogen bulbs and convert a higher percentage of energy into light rather than heat. However, they still produce some heat. By dimming the LEDs, less energy is consumed, which means less heat is produced. This can reduce the strain on air conditioning systems and further save energy.
• Advanced Controls: Many dimmable LEDs are compatible with advanced lighting control systems. These can automatically adjust lighting levels based on the time of day or occupancy, which can lead to significant energy savings.

Are There Any Safety Considerations for Using Dimmable LED Technology?

Dimmable LED technology can positively impact energy consumption in a few ways:

Yes, there are some safety considerations to keep in mind when using dimmable LED technology:

• Compatibility: Ensure that the dimmable LED lights you are using are compatible with the dimming system or dimmer switch you plan to use. Not all LED lights are compatible with all types of dimmers. Using incompatible dimmers can cause flickering, buzzing, or improper dimming performance, and it may even damage the LED lights or the dimming equipment.
• Proper Wiring and Installation: Follow the manufacturer's instructions and guidelines for the wiring and installation of dimmable LED lights. Incorrect installation or wiring can lead to electrical hazards or affect the performance and lifespan of the LED lights.
• Overloading the Dimmer: Be mindful of the maximum load capacity of the dimmer switch. Each dimmer has a maximum wattage or current rating it can handle. Ensure that the total wattage of the dimmable LED lights connected to the dimmer switch does not exceed its capacity. Overloading the dimmer can lead to overheating, reduced lifespan, or malfunctioning of the dimmer or LED lights.
• Dimmer Range: Pay attention to the dimming range of the LED lights. Some LED lights may have a limited dimming range, meaning they may not dim all the way to complete darkness. This limitation can affect the desired lighting effect or may not be suitable for certain applications.
• Safety Standards and Certification: Choose dimmable LED lights that comply with relevant safety standards and certifications in your region. Look for certifications such as UL (Underwriters Laboratories), ETL (Intertek), or equivalent certifications that ensure the safety and performance of the LED lights.

What are the Different Mechanisms Used in Dimmable Technology for Controlling Brightness?

There are several mechanisms used in dimmable technology to control the brightness of LED lights. Here are some commonly employed methods:

Triac Dimming

This is a legacy technology, originally designed for incandescent lamps, that reduces the amount of power delivered to a light source by cutting off portions of the voltage waveform. It's either on the leading edge or trailing edge of the wave. However, this method can cause challenges when used with LEDs due to their low power requirements and different load characteristics compared to traditional incandescent or halogen lamps. For LED applications, Triac dimmers can lead to flickering, limited dimming range, and may even reduce the lifespan of the LED.

Yes, Triac dimming can be used with LEDs, but it's not the optimal solution due to the aforementioned challenges. Some LED light fixtures incorporate built-in circuitry to be compatible with Triac dimming, but the dimming performance may not be as smooth or broad-ranging as with incandescent lamps. Using dedicated LED dimmers or specific dimmable LED drivers can help achieve better results.

Triac dimming is still commonly used in retrofit situations where replacing the existing dimmer is not desirable or feasible, such as in some residential and commercial lighting applications.

Leading Edge (Forward Phase) Dimming

Leading edge dimming, also known as forward phase dimming, works by cutting off the start of each AC cycle. The amount of the cycle that's cut off determines the level of dimming. This method is commonly used with incandescent and halogen lights. However, it can create problems when used with LEDs, such as flicker, buzz, or reduced lifespan, due to the inrush current at the start of each cycle.

Despite potential compatibility issues with LEDs, leading edge dimming is still widely used in residential and commercial applications due to its cost-effectiveness and simplicity.

Trailing Edge (Reverse Phase) Dimming

Trailing edge dimming, also known as reverse phase dimming, cuts off the end of each AC cycle to control the brightness of the light. Because this method results in a smoother delivery of current, it is generally more compatible with LED lighting and less likely to cause flicker or buzz.

Trailing edge dimming is often preferred for LED applications, especially in residential settings where silent and smooth operation is highly valued.

PWM Dimming

Pulse Width Modulation (PWM) works by rapidly turning the LED on and off. The LED operates at full brightness when it's on, and emits no light when it's off. The overall brightness that we perceive is determined by the ratio of on-time to off-time.

Yes, PWM dimming is a preferred method for dimming LEDs. It can work very well with LED lights since the LED is actually operating at a constant brightness when it's on, ensuring colour consistency, making it suitable for situations where color accuracy is critical.

PWM dimming is widely used in theatrical lighting or architectural lighting where precise colour control and consistency are required.

Analog Dimming (Constant Current Reduction)

Analog dimming involves reducing the current flowing through the LED. The brightness of the light output is directly proportional to the magnitude of the current flowing through the LED. However, this method may lead to color shifts as the light is dimmed because the colour temperature of an LED can change slightly with the current.

Yes, analog dimming can be used with LEDs and it is quite straightforward to implement. However, the potential for colour shifting as the light is dimmed might make this method less suitable for situations where colour accuracy is important.

Analog dimming is typically used in simpler lighting systems, like basic desk lamps or residential lighting, where colour shift is less of a concern.

Digital Dimming

Digital dimming typically involves a microcontroller sending digital signals to the LED driver to control the output. This allows for precise, programmable control over the light output.

Yes, digital dimming can be applied with LED lights. Because digital signals are used, this method allows for precise control over brightness levels and can even enable more advanced features like colour mixing or scene control in multi-colour LED systems.

Digital dimming is often implemented in smart lighting systems where individual control over multiple lights or zones is needed, or in entertainment lighting where precise control over light colour and intensity is required.

Wireless Dimming

This method involves sending the dimming control signal to the LED driver wirelessly using technologies like Wi-Fi, Bluetooth, or proprietary wireless control protocols.

Yes, wireless dimming is compatible with LED technology. LEDs equipped with wireless receivers can be remotely controlled, providing convenience and advanced control features. However, the LED fixtures or bulbs must be designed to be compatible with the specific wireless dimming technology being used.

Wireless dimming is commonly used in smart homes and modern office environments, allowing users to adjust lighting conditions from their smartphones or through voice-controlled smart home systems.

Smart Dimming

Smart dimming generally refers to dimming that's controlled by intelligent systems. These systems can automatically adjust light levels based on factors like time of day, occupancy, or even the type of activity being performed.

Yes, smart dimming can be used with LED lighting systems. In fact, the energy efficiency and digital controllability of LEDs make them ideal for use in smart lighting systems.

Smart dimming is often used in modern homes and commercial spaces, where it can help to improve comfort, convenience, and energy efficiency. It's also widely used in street lighting to save energy during times when full brightness is not required.

DALI (Digital Addressable Lighting Interface) Dimming

DALI is a digital communication protocol designed specifically for controlling lighting. It allows individual lights to be addressed directly and can provide feedback about the status of each light. The system can be used to control brightness, color temperature, and even the color of individual lights.

Yes, DALI can be used with LEDs. In fact, the precise digital control that DALI offers is ideal for LED lighting systems. However, implementing DALI requires compatible hardware and often a more complex setup than other dimming methods.

DALI dimming is commonly used in commercial or industrial settings where complex lighting setups are common. It's also useful in situations where feedback from individual lights can help with maintenance or energy management.

Remote Control Dimming

This dimming method involves using a remote control to adjust the light levels of an LED bulb or fixture. Remote control dimming systems generally involve an infrared (IR) or radio frequency (RF) remote that communicates with a receiver integrated into the light fixture or bulb.

Yes, remote-controlled LEDs can indeed be dimmed, but the specific method used may depend on the design of the light fixture or bulb. Some remote-controlled LEDs use PWM or analog dimming methods internally, while others may use more advanced digital control methods.

Example: Remote control dimming is common in decorative lighting systems, such as LED strips or colour-changing light bulbs, where it provides an easy way to adjust both the brightness and colour of the light. The remote control provides convenience and flexibility, enabling you to control the lights from anywhere within the remote's range without needing to physically access a wall switch or dimmer.

As with other methods, it's important to ensure that the LED bulb or fixture is designed to be dimmable and is compatible with the remote control system being used. Always check the product specifications for compatibility information.

What are The Different Types of Dimmer Switches?

Yes, remote-controlled LEDs can indeed be dimmed, but the specific method used may depend on the design of the light fixture or bulb. Some remote-controlled LEDs use PWM or analog dimming methods internally, while others may use more advanced digital control methods. CCT tuning, or adjusting the colour temperature of the light, is another feature often available in these systems, and it's achieved by adjusting the relative brightness of different coloured LEDs within the fixture or bulb.Example: Remote control dimming is common in decorative lighting systems, such as LED strips or colour-changing light bulbs, where it provides an easy way to adjust both the brightness and colour of the light.

Always check the product specifications for compatibility information.

Dimmer switches come in various types and are designed to adjust the brightness levels of lights while saving energy and extending the lifespan of the bulbs. Here are some of the most common types:

• Rotary Dimmer Switch: This is the oldest and most common type of dimmer switch. It works by rotating a knob to increase or decrease the intensity of the light. Some models require you to push the knob in to turn the light on or off.
• Slide Dimmer Switch: With this type of switch, you move a slider up or down to adjust the light level. These often have a separate on/off switch.
• Toggle Dimmer Switch: Toggle dimmers look like traditional toggle light switches, but also provide dimming functionality. You can adjust the light level by moving the toggle to a different position or, in some models, by pressing and holding the toggle.
• Touch Dimmer Switch: These switches work by sensing the electrical capacitance of the human body. When you touch the switch, it changes the light level. Some models allow you to cycle through different light levels by repeatedly touching the switch, while others change the light level as long as your finger is on the switch.
• Integrated Dimmer Switch: These are often found on the fixtures themselves, especially on table lamps or floor lamps. They might use any of the above mechanisms (rotary, slide, etc.) or they could be a touch-sensitive area on the lamp itself.
• Smart Dimmer Switch: These are a newer type of switch that can connect to your home's WiFi network and be controlled via a smartphone app, or through a smart home system. Some models allow for advanced features like setting schedules or scenes, and they can usually be controlled remotely.
• Scene or Multi-location Dimmer Switch: These are designed to control multiple lights or groups of lights from one location. They allow the user to create pre-set scenes or moods, each with different brightness levels for each light.

Each of these dimmer types can be compatible with different dimming methods, such as leading-edge or trailing-edge phase-cut dimming, PWM dimming, etc. It's important to ensure that the dimmer you choose is compatible with the specific type of lights you're using, especially if you're using LEDs, which can have specific compatibility requirements.

When choosing a dimmer switch, it's important to consider factors like the type of lights it will control, the overall style and decor of the room, and any special features that might be required, such as smart home compatibility or the ability to set lighting scenes.

Additionally, you must ensure the dimmer switch is compatible with the type of bulbs you are using, especially if they are LED or compact fluorescent lamps, which can have specific compatibility requirements.

What Do "Way" and "Gang" Mean in Dimmer Switches?

When it comes to choosing a dimmer switch in the UK, you'll likely come across the terms "way" and "gang". Understanding these can help you pick the correct dimmer switch for your needs.

• Way: In the UK, the term "way" in a dimmer switch refers to the number of switches that can control a specific light fixture. A "one-way" switch setup allows a single switch to control a light. A "two-way" switch setup, on the other hand, enables a light to be controlled by two switches. This is useful for rooms with two entrances, like a large hallway or staircase. If you need to control a light from more than two locations, you'd use an "intermediate" or "multi-way" switch setup, which involves the use of additional switches.
• Gang: The term "gang" describes the number of switches on a single switch plate. A "single gang" switch plate has one switch, a "double gang" switch plate has two, and so on. These switches can control different light fixtures or separate features of the same light, like brightness and colour temperature.

It's crucial when installing or replacing dimmer switches to match the "way" and "gang" to your room's layout and your lighting needs. Also, always ensure that your dimmer switch is compatible with the type of light fixtures or bulbs you're using, especially when it comes to LED lights, which may require specific types of dimmers.

How Does a Lighting Setup with Two Triac Dimmer Switches Controlling the Same Light Function? Can Both Switches Adjust the Dimming Level Simultaneously? What would Occur if the Dimmers are Set to Different Levels?

You're correct in identifying some of the complexities that can arise when trying to use two Triac dimmer switches to control the same light. Traditional dimmer switches, including Triac dimmers, are not designed to work in pairs on the same circuit. Here's why:

When a traditional dimmer switch is used, it alters the voltage flowing through the circuit to dim the lights. If you have two dimmer switches trying to control that same voltage, they could conflict with each other, potentially causing flickering, buzzing, or even damage to the switches or the light fixture.

In a two-way or three-way lighting setup, typically one of the switches is a standard on/off switch, while the other is a dimmer switch. You can turn the lights on or off from either location, but only adjust the brightness from the location with the dimmer.

However, there are dimmer switches specifically designed to work in multi-way configurations. These switches often include one master dimmer switch and one or more companion switches. The master dimmer controls the light level and sends a signal to the companion switches, telling them what the current brightness level is. This allows you to adjust the light level from multiple locations without the switches conflicting with each other.

What are the Advantages of Using Dimmable LED Bulbs?

There are several advantages to using dimmable LED bulbs:
