Description

Technical Field

[0001] The utility model relates to the technical field of light guide plates, in particular to a high-toughness nylon plastic light guide plate. Background Art

[0002] Light guide plate is a transparent flat material designed using optical principles, mainly made of optical grade acrylic or polycarbonate. Its core function is to transform point light source or line light source into evenly distributed surface light source, so as to achieve efficient and uniform lighting or display. Light guide plate contains special microstructures such as light guide points, V-shaped cross grid or laser engraved lines, which can capture and guide light to reflect inside the plate and finally emit it evenly from the surface of the plate. Light guide plate is a key component that optimizes the light propagation path through high-tech means, which is of great significance to modern display technology and lighting applications.

[0003] Nylon light guide plate, as the name implies, is a light guide plate made of nylon material. Nylon is an engineering plastic known for its high strength, toughness, wear resistance and good chemical resistance. By utilizing the high strength and toughness of nylon materials, light guide plates can be designed to be thinner or used in environments with higher mechanical stress, such as equipment that needs to be frequently moved or has impact risks.

[0004] The nylon light guide plate in the prior art is usually connected to the backlight source by punching holes and fitting bolts. Although this meets the usage requirements to a certain extent, the method of punching holes and inserting bolts inside the guide plate will destroy the arrangement of light guide points inside the guide plate and affect the display effect.
