Acrylic light guide plate, also known as through the light plate, optical grade acrylic sheet as a material, the use of backlight mold line technology, through the high light conductivity of the light guide point, the computer calculation of the light guide point, so that the light guide plate light refracted into the surface of the light source light state of the manufacture of molding. Simply put, acrylic light guide plate is the use of acrylic transmittance, do some inside the acrylic can make the light evenly issued by the light guide point, to achieve the lighting effect we want.

Features of acrylic light guide plate.

a, light guide uniform

Acrylic light guide plate is usually made in a constant temperature, humidity, dust-free environment, with strong light transmission, good transparency, ultra-thin ultra-bright, no dark areas, light guide uniformity, uniformity up to 90% or more.

b、Strong plasticity

Good moldable performance, excellent processing performance, can meet a variety of creative design. Easy to order, texture, color, specifications, structure, shape, etc. can be customized services. At the same time can be arbitrarily cut into the required size, can also be spliced to use, simple process, easy to produce.

c. Superior performance

Small density, light weight, strong impact resistance, good weather resistance, high security. Any light source can be used, including LEDCCFL (cold cathode fluorescent lamp), fluorescent tubes and so on. High light conversion rate, long life, safety and environmental protection, indoor and outdoor can be applied.

d. Cost saving

The same area luminous brightness, high luminous efficiency, low power consumption; the same brightness, you can use thinner products, cost savings.

Acrylic light guide plate manufacturing process.

Acrylic light guide plate manufacturing process is mainly divided into printing and non-printing two kinds.

a, printed

Printed light guide plate is the use of screen printing light guide ink made. Light guide ink has the role of refraction and high reflection of light, can change the direction of the side of the incident light into a plane light.

Advantages

Less investment in equipment, simple operation, high mobility, low cost.

Disadvantages

Uniformity of structure, ink viscosity, screen tension is not easy to control, need a lot of manpower, product quality rate is relatively low.

b, non-printing

Non-printed light guide plate production process is divided into direct injection molding, chemical etching, laser engraving, V-cutting technology. 

① Direct injection molding

According to the backlight product size and thickness of the dot design in the injection mold, and then the PMMA adhesive hot melt through the injection molding machine direct injection molding into the light guide plate.

Chemical Etching

According to the size of the backlight product size will be the first point of the mold, and then the mold and optical grade acrylic board combined and chemically corrode the optical grade acrylic board, generating the point of view.

③Laser engraving

The use of laser engraving machine in the optical acrylic plate surface engraving line groove or concave hole dot matrix. The line groove or concave hole dot matrix can refract the side incident light into a plane light.

④V-cutting technology

The use of high-grade industrial diamonds in conjunction with CNC machine tools to destroy the surface of the optical grade acrylic sheet, thus forming V-grooves, these V-grooves can be adjusted with the replacement of the thickness of the light guide plate.
