Introduction

COSUN’s laser dotted light guide plate has the distinctive characteristics: big size (1220 x 2440mm), customized size, ultra-thin, high brightness, uniformity, energy saving, environmental protection, no dark area, good durability, no fading, easy installation and maintenance, and so on.


Light guide plate can efficiently convert the point light source into the uniform panel light source. It is the latest achievement of the advanced technological integration of optics and materials science.


1. Because of no printing ink and more environmentally friendly, laser light guide plate is more suitable for exporting to Europe market
2. High Luminous Efficiency
3. Laser dotted light guide plate is composed by acrylic with high transmittance over 92.5% of imported optical grade (PMMA brand is Mitsubishi from Japan) and high quality reflective film, which can ensure 90% or above lighting uniformity and high lighting effect
4. Be durable, no fade and long life span, laser dotted light guide plate can last more than 8 years if being normally used
5. Free from water and moisture, cold resistance and high temperature resistant, more suitable for exporting to the countries and regions with bad climate conditions
6. Compared with the traditional screen printing, our laser LGP has changed all the disadvantages such as the complex process opening and the poor durability

Shape Cutted into Any Shape Fixed Shape

LGP is a transparent acrylic panel made from pure PMMA resin, on whose bottom face a dot matrix is printed or a line matrix is scratched. The light source can be installed on its edge(s). It distributes the light coming from the light source evenly over the whole upper face of the acrylic panel. It is a key component to maximize the uniformity of light, to make backlight slim and to reorient the line or dot light source such as fluorescent, decoration lamp or LED to the plate light source.

 

1) Square, round or any shapes                                          2) Thickness: 3mm, 4mm, 6mm, 8mm

3) Single, double or full edged illumination                          4) Raw material: PMMA ( MITSUBISHI brand)
