LED Panel Light Key Technology Analysis
May 11, 2016

1. Panel light aluminum frame:
Are the main channels LED heat sink, looks simple and elegant, you can use the ZY0907, mould stamping mould costs low, low processing costs; die-cast aluminum frame IP rating can be a little higher, surface texture, and overall aesthetic, but the upfront cost is high.
2.LED source:
3528 LED lamp bead used often, others use 3014 and 5050. 3014 and 5050 low cost slightly less luminous efficiency, the key is its optical network design problems. 3528, high light efficiency outlets universal good.
3.LED plate:
Side LED light passing through a uniform export outlets refraction of light from the front, is the key to quality control of LED panel light guide plate. Bad network design, see the overall luminous efficacy is very poor, generally appear bright in the middle on both sides of the dark, or appear in the light, or local area, again inconsistent brightness or a different angle. To improve the Lightguide plate light effect mainly rely on network design, followed by the quality of plates, but no need to first-line brand of superstition plates, qualified transmittance between plates are usually the same. General LED light guide plate of the factory are bought direct public use, there is no need to proof design, more manufacturers usually quality.
4.LED diffusion plate:
Export the Lightguide plate light evenly, can also play a role in Fuzzy network. Diffuser acrylic plate or PC 2.0, almost is PS material, acrylic low cost and high light transmission rate slightly higher than the PC, acrylic crisp anti-aging performance weak, PC are a bit expensive, but strong anti aging properties. Diffuser installed cannot see outlets and light transmittance is about 90%. Acrylic light transmittance at 92%,PC for 88%,PS about 80%, we can choice of diffuser materials according to the needs, the majority of manufacturers are using acrylic material.
