For the backlit LED light panel,its key technology is the control of the brightness uniformity , General speaking, to improve the brightness uniformity needs to increase the thickness of mixed light ,in order to increase the optical path to achieve the best mix of light,.But this bound to make the thickness of the light more heavy and mass loss of light.

For the direct type LED light panel, the usage of HT80-M diffuser makes LED light source to spray diffusion, the principle is that every board in the spread of the formation of stars LED circular spot spread between the spot and spread some overlap. So, see from the positive side, can achieve uniform aerosol effect. Achieve such results, we need to consider three factors.

First, the usage of LED type, different LEDs have different spot in the diffusion plate. We always tend to choose wide bean angle leds.

Second, the distance between leds,In theory, the smaller distance is better, because the smaller the distance between the diffuser and led. But the small distance will makes the power consumption higher. So, it is important to select the appropriate spacing and determine the total power consumption.In addition to that, the arrangement of leds is also very important, the normal is square or rectangular array, equilateral triangle. The principle is the formation of stars LED board in the spread of proliferation and the spread of spot beam overlap between the minimum.

Third, the distance between plate and leds, the smaller distance will lead to less light loss, but the distance between the small bright spot will lead to LED highlight.

So, to design uniformity, no spot, less light loss backlit panel lights, we need pay attaention to the above 3 factors.

We use inported optical grade PMMA.

High transmittance, high haze, up to 82% light transmission rate and 92% haze. At the same time, we use advanced optical design and the proliferation of material to adjust the light propagation direction, to improve the optical brightness and diffusion effects.

The Diffuser is matte and smooth at both sides respectively. Please make sure matte face towards outside when use.

Used in direct type light source for LED lighting, such as down light, grid lamps, high-grade aluminum lights, installed in the LED downlight, the light loss of at least 10%.

Used in LED light source for side lighting, such as flat panel lights, advertising light boxes, lamps professional view films, usually with the use of light guide plates.
