There is a saying, LED panel light is the mainstream of interior lighting in the future. It is no doubt LED panel lights have their special advantages, with uniformity lighting, soft warm light and beautiful simple design, and the LED panel lights are popular in some western countries, and these countries also admit the LED panel light is the best lighting product. In terms of the features of lighting, LED panel light is superior than the traditional grille light, with manufacturing materials’ price decreasing constantly, LED panel lights’ price will be down too.
Today, let’s realize the difference between back lit LED panel light and side lit LED panel light.
Thickness represents the fashion of LED panel lights, so the side lit LED panel light with ultra thin design is the latest fashion in lighting world, as the back lit LED panel lights are thicker. I am curious what determines the thickness of LED panel light, what about you? Lighting usage of LED panel lights determines the thickness of LED panel light. The back lit LED panel light use light from LED chip directly through the diffusion plate, and the light source of side lit LED panel light arrange across from the diffusion plate.
What are the difference between side lit LED panel light and back lit LED panel light in brightness? Which one is brighter? In terms of the feature of LED lighting, the brightness play an important role. The back lit LED panel lights have advantages in brightness and lighting efficiency, can achieve 4200Lm brightness easily, but the side lit LED panel lights output the light by kinds of action of refraction and reflection, through guide light plate, reflection dot mesh and reflection plate etc. So we can see, back lit LED panel light will have a better lighting efficiency than side lit LED panel light, without light failure.
In addition to the brightness, people are also concerned about the quality of light, which directly influence their comfort and health, so the quality of light is the key factor to evaluate a quality LED panel light. The color temperature of LED panel light on the market generally close to blue color, and color rendering index is about 80.
Heat dissipation is a common problem for LED lamp, especial for higher power LED lamp, because the high power LED lamp cause higher temperature. LED panel lights have bigger surface area , which make sure the lamp can not reach to a high temperature. But it is also necessary to do some measure for cooling. Using die-casting aluminum material or designing wave shape to increase the cooling area or drilling a hole on the PCB etc.
Anyway, although the LED panel light just exists at a short time, it is popular in public, it is not only a replacement for conventional lamp, but also a lighting lamp combined with all of its special features.
