3W COB LED Chip For Down Light

Guangmai Technology is proffesional in making the 3W COB LED Chip for Down Light.

How to choose good COB LED Chip for the LED lamps?

1. The heat dissipation of the internal chip of the COB has a very large relationship with the size of the light-emitting surface. The COB current density of the small light-emitting surface requires higher heat dissipation conditions. The COB current density of the large light-emitting surface is relatively small, and the heat dissipation requirements are relatively lower, but high power For heat dissipation under high current conditions, it is necessary to consider using a large light-emitting surface as much as possible to ensure light efficiency and reliability.

2. COB brand choice, each brand has its own strengths, some brands are strong and have high terminal recognition, some product lines have full power, some have good color consistency, and some have high luminous efficiency. Choosing COB should be based on the positioning of its own lighting brand. For example, when doing circulation lighting and engineering, it is necessary to choose different COB products for positioning.

3. The choice of COB is inseparable from optical matching. This work should be carried out at the same time. The quality of a luminaire, the effect of on-site application is very large because of the matching decision of COB and optical devices. It is very important to ask about the most suitable optical device combination for each model of each COB brand. The best course is to develop optics for each luminaire for the project.

4. After confirming the COB LED and optics, install the heat sink of the lamp to test whether the overall heat dissipation design is reasonable. If it is unreasonable, you need to adjust the heat dissipation structure or reselect the COB and optical solutions. However, in principle, after selecting the COB and optics, The heat dissipation design should be modified to match the former.
