Why not drive LED high power COB lamp?
COB integrated light source will be placed in a plurality of LED chips are fixed on the substrate, the emitted light is light, no glare, color index can be higher than the high power LED, the working current of only tens of Ma can be, the product temperature will be relatively low, on demand as a cooling device high power LED as high.
High power LED light source is a point source, single use flux to inadequate lighting applications, need more light bead combination, so that the light emitted by the glare, in this light for longer, more eye fatigue, and even affect people's vision; current David training and working (or a few hundred Ma above), the product temperature will be very high, need to add another good cooling device can work normally
The relationship between high power LED band and color
