There are several weakness of LED lamps waiting for improvement. One particular of them would be that the light is a little little too sharp for human being eyes. Stare at the clean LED light source for seconds and sight will not be very comfortable. led panel light
Not that friendly as incandescent lights. A lot of lamps are by using a liquid glass to diverse these light, and try to give a much better feeling. These kinds of lamps have become better. A single of these lamps are LED panel lights, that can come from the idea of Grid light. Of course there are also LED grid lighting in the market, which include 3pcs of conduit lights in a main grid base. Not bad, but from the frosted lights idea, designers learn to make a whole panel light, as opposed to some pcs of tube lights.
So, just how do we make a perfect such light? We use SMD led as the sunshine source, which usually be SMD5050 and SMD3528 Led. SMD5050 and SMD3528 are also the key light source of Led line lights.
Similar with Added strip lights light, CONTRIBUTED panel lights use hundreds of SMD3528 or SMD5050 to finish one plank unit. There are two main types of LED panel lights in the market. One is electricity inside, the other is power supply outside the panel. The previous one must be relatively more thick, some might be 8cm, with the SMD pcs on the lower part of the panel. The latter can be only 3CM, with the SMD on the side of the
panel. Which their better? Not certain. The thick one can be better theoretically, but it also will depend on the making and the materials.
To measure a LED plank light we give attention to some aspects.
1, the PCB design.
2, light source.
3, the power factor.
