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

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.

Brightness

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.

Cooling

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.

The light sources of back lit LED panel light are LED chips, there is a distance between LEDs, so it is unavoidable to produce light spot . Lighting industries always take use of the diffusion plate HT80-M to make lamp with uniformity light.

For settling light spot of back lit LED panel lights, why do we choose diffusion plate HT80-M? Let’s look the features of diffusion plate HT80-M.

1. The superior materials of this diffusion plate HT80-M is imported optical level PMMA.

2. High light transmittance up to 82%, high diffusion efficiency up to 92%, using advanced optical design and diffusion material, can adjust the lighting direction, enhance the optical brightness and diffusion effect.

3. One side of diffusion plate is matte, and other side is glossy. You should put the matte side outward when you use it, because three points as below.

a. Glossy side as the lamp surface is easy to fouling.

b. Matte side as the lamp surface is not easy to bruise and scratch.

c. Enhance the light transmitting efficiency(the conclusion of the integrating sphere test)

Application area:

1. Suitable for back lit LED lamp, such as LED tube light, LED grille light etc. If you install it on the LED tube light, the smallest light failure is 10%.

2. Suitable for side lit LED lamp, such as some side lit LED panel light, and this diffusion plates are always used with light guide plate.

The light source always are several LED chips, but it has a distance between these LED chips, so according to the different lighting intensity on different position of plate, there are some light spots occurring on the plate. It also is an important problem for LED panel light industry, then how to resolve the light spot on the LED pane light ?

1. If you want to settle the problem of light spot, the key technology is to control the luminance uniformity. Generally speaking, in order to enhance the luminance uniformity, the thickness of cavity must be increased for increasing the lighting distance and achieving the best light mixing, but which will make the lamp with a bigger thickness and create larger lighting failure.

2. Using the diffusion plate HT80-M to spread the range of electric light source. The principle is ensuring there are some mixing between the larger diffusion round lighting spot, so that the lamp can achieve uniformity lighting. Therefore, when we talk about how to settle about light spot for back lit light LED panel light, we should consider below three points:

a. To choose a suitable LED chip. Different LED chip form a different light spot on the diffusion plate, so you should try your best to select a LED chip with big lighting angle.

b. The distance between LED chip. In terms of theory, smaller distance between LEDs is better, because smaller distance between LEDs means smaller distance between diffusion plate, but too small distance of LED will cause high power consumption of the whole lamp, thus it is important to choose a suitable distance between LED chip to ensure a suitable power consumption. In other hand, select a right position to put down the LED chip is also important, the common ways to arrange the LED are square, rectangular, equilateral triangle, the principle is to make a smallest mixing area between diffusion light spot on the diffusion plate.

c. The distance between diffusion plate and LED. Smaller distance between diffusion plate and LEDs means less light failure, but it also means LED lighting spot occurring. So the quality direct light LED panel light must meet three requirements of uniformity, no light spot, less light failure.

The reason Why LED panel light developing so fast:

With the development of society and the enhancement of people’s living standard, the ordinary lighting lamps are already not suitable for the demands of people any more, people begin to pursuing a green environment- friendly life, and the LED panel light meets the consumers’ consumption requirements as well.

Firstly, LED pane light has features of energy-saving and environmental protection, with advantages of high lighting effect and high brightness, when it works, the LED transformation efficiency of electricity and light is 3 or 5 times higher than traditional incandescent lamp, which means the LED panel lights can save 60% energy than the tradition incandescent lamp under the occasion of same brightness effect, of cause, the LED pane light will have a higher brightness than conventional incandescent lamp under the occasion of using same energy. LED panel light lighting technology is a green lighting technology, can manufacture a lighting products without mercury and less failure material as well as no pollution.

secondly, the LED panel light can not only provide lighting, but also increase the beauty of art. LED panel light use the special SMD LED chip as the light source, combining with the light guide plate and diffusion plate, so that LED panel light have a ultra thin design, bringing a kind of beautiful feeling for people and having good lighting effect.

Finally, the LED panel light with features of ultra thin body, complete function of radiation, low temperature and long life span, can be controlled by the controller through the dynamic program, such as to adjust the color temperature and brightness. The LED panel lights do not produce the radiation and flashing, are friendly for people’s eyes, with warm light color, steady performance, low fixing efficiency, high cost-effective, and it is convenient for transport and installation.
Because the superior performance and special features, the LED panel light are accepted by public at a short time. When the LED panel light occurs in the market, the main competitors are T5, T8 grille light mainly using conventional fluorescent light source. But with the time goes by, the price of LED panel light is closer to the traditional grille lights’, LED panel light completely show their competitive ability, are more and more popular with consumers.

The trend of LED panel light

1. Take use of the high efficiency energy-saving light source. For recent years, with the promotion of energy-saving lighting technology, the design of energy saving lighting lamp become the major concern of lamp manufacturers, and the lamp manufacturers also realize an energy saving light source is the first idea to promote high efficiency energy-saving, then the second idea is to design a lamp with high utilization efficiency and great decoration effect according to the size of light source.

2. Development for multi-function and smaller. With the development of compact light source, kinds of new technology and new art join in the electrical application, ballast resistor and other electrical application accessories get smaller, LED panel lights also develop to smaller, more durable and multi-function. In order to accommodate the changeable modern architecture, meet kinds of function requirement and try our best to utilize building space, the lamp develop for combination with kinds of function and kinds of shape.

3. Combination with computer. With the deep researching and application of lamp, electrical ballast resistor is the representative developing for electrical technology, so that there are considerable improvement in application of kinds integrated device and computer controlling to lamp or lighting system, which show at the function of lighting system such as dimming, remote control, light color control and so on.

4. Development for lighting and decoration. LED panel lights are designed with modern scientific technology, combining classical model with modern beauty, to show the modern lighting for public.
