Product Description:

Product Name:Light guide panel

 

Working principle:
The light guide plate is usually flat and is generally made of acrylic (PMMA). The light is introduced into the plate through the edge-mounted LED. Using the principle of internal reflection, the light is reflected inside the plate until it encounters the dot matrix or micro-etched pattern on the surface, which scatters the light evenly so that the light is emitted evenly from the surface of the light guide plate.
Material characteristics: The commonly used material is PMMA, because it has high light transmittance, good stability and easy processing. Compared with cheap plastics such as polystyrene (PS), PMMA light guide plates can provide better clarity.
Product specifications:
Thickness: Usually between 0.3mm-20mm, common ones are 1.5mm, 3mm, 6mm 8mm 10mm, etc.,
Size: Can be customized according to needs, the maximum size is 1220*2440mm

Performance advantages:
Good light uniformity: It can effectively eliminate dark areas and hot spots, and achieve high-quality uniform light emission. It is suitable for places with high requirements for light uniformity, such as retail displays, TV backlights, etc.
Ultra-thin design: The edge light guide method is adopted, and there is no need to set up bulky light sources behind the display screen, which can make the product ultra-thin and meet the design requirements of modern electronic products.
Energy saving and high efficiency: Through efficient edge lighting and optimized light diffusion, power consumption can be reduced. The energy saving effect is more significant when combined with LED technology. It can also reduce the number of LEDs used while achieving the same brightness while reducing material costs and thermal management difficulties.
Flexible design: It can be customized into various shapes, such as round, square, arc, etc., and can also achieve specific lighting effects through pattern design, which is convenient for integration with different lamps or display devices.
Processing technology: Common processing technologies include silk screen printing, laser engraving, machine engraving V-groove, etc. The light guide plate with laser engraving and machine engraving V-groove technology has UV protection, and the brightness contrast is higher than that of the silk screen light guide plate. The dimensional tolerance can be controlled at 0.1mm, and the service life is up to 7-8 years.
Application areas: Widely used in architectural decoration, lighting exhibition and other industries, including supermarket shelf lighting, LED signs, stone backlighting, LCD display screens, LED light box backlighting, etc.
Quality standards: Some products must comply with international standards, such as UL fire rating, RoHS environmental standards, etc., to ensure their safety and environmental protection.

The difference of PMMA ,PC,PS

There are three main materials for light guide plates: acrylic (PMMA), PC materials, and PS materials.

Acrylic is the most widely used material for backlights. When screen printing dots are used, it is cut with acrylic sheets to make backlights of corresponding size. Its light guiding performance is best, and the price is between PC material and PS material.

 

PC material, open-mode light guide plate, and the backlight with column will generally use PC material. For backlights with temperature requirements, PC material will generally be used. The price is the most expensive among the three materials.

PS material, open-mode light guide plate, has the requirement of price and cost, good light guiding effect, low price and temperature resistance.
