As the LED panel lights was used for indoor illumination, which is totally different from the situation illumination, so the brightness is very important. There are two kinds of illumination for the LED panel lights, one is the direct lighting, the other is the side lighting. The direct lighting is cheaper, but too sharp for the human being's eye, so most of the manufacturer focused at the side lighting panel lights.
The brightness has a great links with LED lumens and LED quantity, lamp beads, chip brand, packing, light guide plate. Also it is used for the commercial lighting usually, so you have consider of the appearance of the panel. Here are six tips for choosing LED panel lights:
1. LED lumens and LED quantity
Please kindly note it that a few manufacturers rise the working current to make the each lamp beads to get more brightness. In this case, the suppliers could decrease the quantity of the lamp beads, thus they can save a lot of costs. But in this way, the heat load of each lamp beads will become very big, which will shorten the lifespan and accelerate the light fades very seriously. Normally you will see bad results after three months.
2. Lamp beads:
There are thousands of LED lamps manufacturer, from small to big. Small factories don't have Spectrophotometric and color-separation machine, either they didn't care about the color, or they subcontract the parts, thus it is very difficult for them to guarantee the quality of the lamp beads. Big factories have Japanese, German, or American machines, it's more easy for them to control the quality.
3. The chips brand:
There are three main standard chips in China. The first-class team is mainly the American chips, Japanese chips, German chips, and other European chips. The second-class team is mainly the Taiwanese chips, Korean chips. The third-class team is mainly the Chinese chips. For the high-end market, most of the big manufacturers use the Taiwan chips, whose cost effective is the highest.
4. The packings:
Normally there are two kinds of packings, one is the resin packing, the other is silicone packing. The resin packing is cheaper compared to the silicone packing, but the heat radiating is not so good as the silicone packing.
5. Light guide plate
For the LED panel lights, you have to consider the CGI, which indicate the comfortable degree of your eye towards the LED panel lights. There are several types of light panel plates, such as silk-printing plate, laser dots plate, V-groove plate, high-polymer plate etc.The best is the silk-printing plate, of course it is the most expensive one. Its thickness mainly include 3mm, 4mm, 6mm, 8mm. The main factors to judge the plate is whether it can guide the light more efficiently and more even while the plate color and surface remain the same in a long time.
6. Frames and other parts:
Normally the manufacturer would use Aluminum 6063 or 6061 as the panel lights frame, nearly both two types are of the same standard. For the frame appearance, there are many styles, refer to our factory, we have the six styles, Simple style, European style, Narrow style, Thin-edge style, Non-frame style, Ceiling-hook style. The rear cover mainly have two types, 0.8mm and 1 mm, some use the steel material to save some cost. |
