LED lights are constantly improved to bring about better use, greater versatility and more efficient use of power. The different models of LED lights are highly popular compared to traditional incandescent lights, mainly because they can last for about 25 times longer with less energy use.
LED lights come in a variety of models. Start comparing COB vs SMD LED Lights, or before you look at the difference between LED light COB and SMD.
You can choose between SMD vs COB types, for example, depending on your needs for energy efficiency and versatility. The COB vs SMD LED Lights differ in terms of their features and semiconductors.
SMD, or &#;Surface Mounted Device&#; LEDs, are the most common LEDs in the market. The LED chip is permanently fused to a printed circuit board, and it&#;s highly popular due to its versatility. You can find it in light bulbs and string lights, and even in the notification light on your mobile .
The SMD LED chips come in a variety of sizes. SMD LED can accommodate chips with complicated designs, like the SMD , which is 5mm wide. The SMD , on the other hand, are 3.5mm wide. The SMD chips are small, almost close to the design of the flat, square computer chip.
One of the distinct features of SMD LED chips is the number of contacts and diodes they have.
SMD LED chips can have more than just two contacts (which makes it different from the classic DIP LED). There can be up to 3 diodes on a single chip, with each diode having an individual circuit. Each circuit would have one cathode and one anode, leading to 2, 4 or 6 contacts in a chip.
This configuration is the reason why SMD chips are more versatile (comparing SMD vs COB). The chip can include a red, green, and blue diode. With these three diodes, you can already create virtually any colour simply by adjusting the output level.
SMD chips are also known to be bright. They can produce 50 to 100 lumens per watt.
One of the most recent developments in LED, COB or &#;Chip on Board&#; technology is a step forward more efficient energy use.Like the SMD, COP chips also have multiple diodes on the same surface. But the difference between LED light COB and SMD is that COB LEDs have more diodes.
COB chips typically have 9 or more diodes. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes. This simple circuit design is the reason for the panel-like appearance of COB LED light (SMD light, on the other hand, appears like a collection of smaller lights).
But unlike SMD, COB LED lights can&#;t be used to create colour changing bulbs or lights. This is because there are only 2 contacts and 1 circuit. Multiple channels for adjustment are required to create the colour changing effect. Because of this, COB LED lights are efficient in single-color applications, but not in more versatile technology.
Another aspect of the COB vs SMD LED Lights difference is in the use of energy. COB is known for better lumen-per-watt ratios and heat efficiency. This has a lot to do with the design of COB LEDs, and the cooling ceramic substrate of the chips.
Before, heavy duty technology like spot lights and flood lights made with LED were non-standard, because you&#;d need multiple LED sources to produce that kind of high lumen output.
But now, COB chips can produce a large amount of lumens with less energy. You can find it in all kinds of bulbs and applications, such as the flash of your mobile or point-and-shoot camera. Its range is higher with a minimum of 80 lumens per watt.
The first question you may have is, 'What is SMD LED?' SMD LED lighting is a type of LED light that uses surface mount technology to place an array of small light-emitting diodes (LEDs) onto a metal-core circuit board. The board is then connected with conductive tracks and soldered in place. This combination of components allows the LEDs to produce bright, efficient light without producing heat.

SMD LED lighting is becoming increasingly popular in comparison to other types of LED lights. There are several benefits that include:
They are brighter than normal LED lights as they produce wide beam angle
Cheaper than COB and high power LED lights
They generate less heat while producing brighter light
Can be mounted directly to the circuit board
Cost effective as they have an estimated life of 50,000 hours or more
SMD LED Types
Now that you know what is SMD LED, it would be good to know that there are several types of SMD LED to choose from. As the technology continues to improve, so too does the variety of SMD LED options. There are SMD LEDs shaped like tiny rectangles and square chips, as well as light bars and strips that feature multiple LED chips side by side. Let us discuss some of the most common SMD LED types:
SMD RGB LED
As the name suggests, an SMD RGB LED is a colourful LED option that allows the colours of the LED to change with its three diodes: red, green and blue. The diodes mix to precise intensity to create different colours. They are perfect for an aesthetic lighting experience and have practical applications as well.
SMD Strip Light
SMD strip lights are one of the most popular applications for SMD LED technology. They provide a uniform, dynamic light source that can be used in any number of commercial and residential applications. They have low LED power consumption and can be used aesthetically. They can offer cove lighting, shelf lighting, backlighting for signs, or task lighting and are highly customisable to suit any need.
SMD LED Size Charts
SMD LED size charts create specifications and set up parameters such as light intensity, colors, sizes and product numbers when selecting SMD LEDs. This makes it easier for buyers to choose the right SMD LED type for their specific needs. With the help of SMD size charts and specification sheets, customers can get a better understanding of what options are available and how those options compare with one another. Given below is an SMD LED size chart for your reference:

SMD LED Voltage
A typical 0.5 Watt white SMD LED voltage is usually around 3.2 Volts. While a 0.2W one uses approximately 3 volts. It is important to note the different categories of LEDs that relate to the power output they can provide. Working with must be done carefully as incorrect levels of power can cause connections to blow out or destroy the chip itself.
SMD Component List
For electronic devices using SMD LED lights, it&#;s important to make sure you have all the right components. Commonly used SMD LED components list in a project includes a capacitor, resistor, and transistor. These are integral to regulating the current flowing through the device in order to ensure that it functions properly while avoiding overloads or burnouts. Make sure that your components match the specifications of your project for its safe operation.
