LED lights do not contain lead, mercury and other pollution elements, no environmental pollution, the advantages are many. But there are still some problems affecting the popularity of LED lamps, LED 8 large following is the basic problem in the care industry applications:
1, led the application of a single LED color problem, basically there is no color issues, but if put to use along with a large number of LED lights at the same time or one with multiple LED, the color problem will highlight came.
2, LED insulation problems mentioned here refers to the heat insulating substrate of the LED's positive and negative terms, yet so far as to solve the fundamental problem, just take remedy measures such as insulation aluminum substrate to deal with, and we may feel incomprehensible . Single LED is not insulated, little impact, there is a problem when multiple satellites in series
3, LED anti-pulse problem with this issue with the manufacturer remains controversial, in my practice do exist, the main reaction in the cold pulse, namely the power instantaneously, a few LED in the cold, that momentary electrical breakdown or disconnection .
4, LED light-emitting angle of the problem because each vendor's LED lens package is not the same even in the same light angle (nominal angle), the effect is not the same, making the selection of poly mask harder still to not be universal.
5, LED potentially blinding hidden LED light points too focused on making the center of the super brightness, it is easy to hurt people's eyes, although some lighting manufacturers make efforts in this regard, but because of the lag and regulations, can only be human problem.
6, LED heat problem in theory, LED less heat, but due to the current immature technology, LED fever be well known.
7, LED efficiency is low (luminous flux) LED current electrical conversion efficiency is too low
8, insufficient brightness LED brightness is insufficient, making the current LED lighting industry can only play a supporting role, mainly for decoration.
