COB stands for Chip on Board
COB LEDs feature multiple light diodes packed closely together on the printed circuit board, requiring it to have a heat sink in the middle made of aluminium, used to dissipate heat products by the lights. This means that it can live in high temperatures for a longer amount of time making it a better choice for high pressure environments like street lighting and industrial lighting. However, this leads to more inbuilt cooling capacity than SMDs being needed for COBs. It also means that they are more energy efficient, producing about 80 Lumens per watt in comparison to SMDs producing around 50 Lumens per watt.
Chip on Board LEDs tend to be a more higher quality light source as they use reflectors to provide a more uniform, bright, and high-quality illumination. They also don&#;t feature the frosted lenses that come with SMD LED Lights. This means you can expect a more crisp and clear light with no glare that is ideal for rooms with higher ceilings. As a result, these LEDs are referred to as higher end lights and are used for a more architectural look and are best for long-term living in the property they are installed in. They are also very popular with filmmakers and photographers due to the uniform luminosity and wide-angle beam.
SMD stands for Surface Mounted Devices. SMDs are the most common types of LED in the market, this is because they are mounted on the surface of the printed circuit board, featuring a compact design that is almost identical to flat, square computer chips.
Whereas SMD LEDs do not tend to be quite as energy efficient as COB LEDs, they are still a very energy efficient option compared to non-LED bulbs and offers a wider range of colour temperature from K warm white to K daylight white, whereas COB LEDs are usually just the one colour temperature.
SMD lights are also best used as a point light due to it having a glare as a result of multiple surface mounted light sources, causing a coupling effect. As a result, SMD lighting is usually best suited for signage in bars, clubs, hotels, and restaurants, as well as use in outdoor wall lighting and spotlights in general. Ideal for use in bathrooms and kitchens as task lighting.
We hope that this guide has helped you understand the differences between COB and SMD LEDs, and has helped you weigh up the pros and cons of each to decide which light is the best fit for your home. From bright bathroom, outdoor, and spotlighting, to softer table lamps, floor lamps and ceiling lights you can guarantee that Litecraft has an LED light fitting to suit you.

Conclusion
LED lights are continually being upgraded to increase their usability, adaptability, and energy efficiency. When compared to standard incandescent lights, LED lights are extremely popular since they may last up to 25 times longer while using less power.
COB and SMD LED lights are two types of LED lights available, which are the two primary sources of light these days. Both of these components create high-quality illumination and have a lengthy life expectancy, as well as the highest efficiency to date.
In this case, we will talk about COB LEDs, which are the latest in the LED industry and provide a number of advantages over the previous options.
One of the most recent developments in the world of LEDs is "Chip on Board" (COB) technology. When contrasted to other standards, we can consider it quite recent and innovative.
COB lights are made up of an arrangement of LED chips that are tightly packed and attached to a silicon carbide base. As a result, one huge LED chip with outstanding illumination uniformity is created, making it perfect for many professionals such as filmmakers and photographers.
Generally, COB chips feature nine or even more diodes. Irrespective of the number of diodes, COB chips only have two contacts and one circuit. On a big chip, this can result in more powerful lighting of up to 250 lumens (at 20mA). The panel-like aspect of COB LED lights is due to the chip's basic circuit design.
COB LED lights, unlike SMD LED lights, cannot be utilized to make color-changing lamps or lights. That is due to the fact that there are only two contacts and one circuit. To achieve the color-changing illusion, several modification channels are needed. COB LED lights are hence effective in single-color applications.
The longevity of a COB LED is determined by how they are used as well as how much heat they are exposed to. A COB LED has an average rated lifetime of 50,000 hours. That is assuming a person uses them for 12 hours a day on average.
There has always been a trade-off between both the amount of high-quality lumen output (brightness) and the duration of runtime through battery operation when building a battery-powered lighting system. If you utilize the same size battery, the more high-quality illumination you want, the shorter the runtime will be. That has become considerably less of a concern with the emergence of COB LED tech.

COB LEDs with little power can produce exceedingly high-quality, ultra-bright light. As a consequence, a COB LED-based lighting system may be powered for extended periods of time using a relatively tiny and lightweight lithium-ion battery pack.
To begin, a basic understanding of Surface-Mounted Device (SMD) LEDs is required. They are by far the most widely used LEDs on the market today. The LED chip is firmly fused to a printed circuit board and is widely utilized due to its adaptability, even in the notification light on the smartphone. The amount of diodes and contacts on SMD LED chips is one of their most distinguishing features.
More than two contacts are possible on SMD LED chips. On a single chip, up to three diodes can be found, each with its own circuit. An anode and cathode would be used in each circuit, resulting in 2, 4, or 6 connections on a chip.
SMD LED chips can include up to three diodes on a single chip, each with its own circuit. In a chip of this type, each circuitry contains a single anode and one cathode, resulting in 2, 4, or 6 connections. COB chips typically have nine or even more diodes. Furthermore, irrespective of the number of diodes, COB chips have two contacts and one circuit. COB LED lights have a panel-like appearance, whereas SMD LED lights would seem like a collection of smaller lights due to this straightforward circuit design.
The SMD LED chip could have a red, green, and blue diode. By employing those three diodes, you can generate any hue simply by altering the output level. But there are just two contacts and one circuitry on COB LED lights. They can't be utilized to create color-changing lights or bulbs. To achieve the color-changing appearance, multiple channel modifications are needed. As a result, COB LED lights are effective in single-color applications but not in multi-color uses.
The luminosity of SMD chips is well known, and they may generate 50 to 100 lumens per watt. COB is noted for its high heat efficiency and lumens per watt ratio. With a minimum number of 80 lumens per watt, COB chips could emit more lumens with less power. It can be found in a variety of bulbs and applications, such as a point-and-shoot camera or your 's flash.
In SMD LED chips, a smaller current capacity is necessary; however, in COB LED chips, a large current capacity external energy source is needed.
COB LED lights, as a basic guideline, are higher-quality light emitters. This is due to the fact that they use reflectors to create concentrated and regulated light. They also lack the frosted lens that comes standard with SMD LED lights.
COB LEDs are a higher-end LED that has a more structural look. In case you intend to live with your LED bulbs for a long time, a COB is a way to go; if you are located in an investment property, SMD will suffice.
You should expect brighter, clearer lighting. COB LED lights, for example, are useful in high-ceiling areas.
COB LEDs have a wide range of applications, extending from residential to industrial utility, with some of them being:
COB LEDs are becoming more popular in lighting applications as designers discover the advantages of employing them over typical standard LEDs. It's difficult not to take into account them for any led light application structure because of:
COB LEDs are the most recent and advanced tech available today. Simply said, they are brighter, use less electricity, and provide a higher-quality beam of light than previous LED technology now used in most trade show illumination.
