The differences between LED integrated light source and COB light source are as follows:
< br >
1. The LED chips used are different
< br >
LED integrated light source is generally the use of more than 1 watt of large size high-power LED chip, chip size is generally more than 30MIL.
< br >
The COB light source is mainly based on a low-power LED chip of less than 1 watt, and a very small number of COB light sources will also use a high-power LED chip of more than 1 watt.
< br >
2, the use of different brackets
< br >
The bracket used by the LED integrated light source is only 10W, 100W, 500W and other square brackets, whose material is mainly copper, and the bracket has two side feet.
< br >
The support used by the COB light source has many sizes, its shape has dozens of kinds of brackets of square, rectangular, oval and other sizes, its material is mainly aluminum, there are also copper and ceramic brackets, generally without side feet.
< br >
3, the use of light sources in different areas
< br >
The main use of LED integrated light source is to make LED floodlights, LED street lights and other outdoor lamps, and its single maximum wattage can reach 500W.
< br >
The COB light source is mainly used in led downlights, track lights, sky lanterns and other indoor lamps, and its single maximum wattage does not exceed 50W.

Extended information:
< br >
COB integrated light source is widely used in LED bulb, LED lamp cup, LED spot light, LED downlight, LED sky lamp, LED bean lamp products, is one of the mainstream trends of LED lighting source.
< br >
LED lamp is a light-emitting diode, is the use of solid semiconductor chip as a light-emitting material, compared with traditional lamps, LED light energy-saving, environmental protection, color rendering and response speed is good.
< br >
1, energy saving is the most prominent feature of LED lights
< br >
In terms of energy consumption, the energy consumption of LED lamps is one-tenth of that of incandescent lamps and one-fourth of energy-saving lamps. This is one of the biggest features of LED lights. Nowadays, people advocate energy saving and environmental protection, and it is precisely because of this feature of energy saving that the application range of LED lights is very wide, making LED lights very popular.
< br >
2, can work at high speed switch state
< br >
We usually walk on the road, will find that every LED composed of the screen or screen is unpredictable. This shows that LED lights can be high-speed switching work. However, for the incandescent lamps we usually use, we can not achieve such a working state. In normal life, if the number of switches is too much, it will directly lead to incandescent filament breakage. This is also an important reason for the popularity of LED lights.
< br >
3. Environmental Protection
< br >
The interior of the LED lamp does not contain any heavy metal materials such as mercury, but it is contained in the incandescent lamp, which reflects the environmental characteristics of the LED lamp. People now attach great importance to environmental protection, so there will be more people willing to choose environmentally friendly LED lights.
