What is a surface light source and a side light emitting desk lamp? Has anyone used it?
Bought a back try, really can not see the light bulb, but also very soft, but also 8 files dimming, a word is very satisfied, decisively discarded before it PHILPS, hope it will be like the seller said in the last ten or twenty years, ha ha.
I bought the best foreign UY-A3 that table lamp, seems to be the side of the light source side desk lamp. When buying to the seller said what beads from one side of the light guide plate light, after light refraction down, forming a surface light source, also said it felt like a sunny day in the shade as comfortable reading.
Is a side emitting LED light source through the light guide plate, guide plate on the dot refraction of light emitted from the light guide plate, looks like a "surface" light emitting lamp light source, the principle is based on a light guide plate, called side light, surface light source. The principle is similar to LED LCD tv.
