New technology of uniform light of led tube
For LED dazzling and flare phenomenon is more serious, people are prone to eye fatigue after a longer time under this kind of lamp. At present, various manufacturers have adopted various methods. Some use brushed PC masks, which can also cause eye astigmatism, and some use Scrub masks use special phosphor materials, etc., but these methods are not ideal. Brushed masks can eliminate glare. If you use them for a long time under this type of lamp, you can use scrub and milky white masks for light loss. Too big, the effect is too bad. After adopting the optical diaphragm, the visual observation of the eyes perceives that each LED is brighter but not dazzling. The diaphragm makes the LED fluorescent light more uniform, and the viewing angle is significantly wider. The working principle of this kind of diaphragm is to change the LED point light source that is irradiated on the diaphragm into a surface light source with uniform output, so that it can solve the problems of glare, light spot and widening the irradiation range at the same time. In addition, the diaphragm is light-transmissive The rate is above 90, with limited impact on contrast
