What is COB lens？
COB (chip on board) lens is a spotlight with COB LED light source as the light source. Its highly efficient integrated surface light source technology allows the LED chip to be directly attached to a high-reflectivity mirror metal substrate. This technology eliminates the concept of brackets, which in turn saves costs.
What are the advantages of COB lens？
1. Good light transmission, up to 92% or more, saving electricity.
2. COB lens has a light transmission rate comparable to glass, but the density is only half that of glass. In addition, it is not as fragile as glass, even if destroyed, it will not form sharp fragments like glass
3. Good weathering and acid and alkali resistance, will not produce yellowing and hydrolysis due to the long years of sun and rain.
4. Light weight, half of the weight of ordinary glass, the building and the support to bear the load is small
