Description

Technical Field

[0001] The utility model belongs to the technical field of light guide plates, and in particular relates to a light guide plate with composite properties. Background Art

[0002] The light guide plate is made of optical-grade acrylic / PC sheets, and then made of high-tech materials with extremely high reflectivity and non-light-absorbing. Light guide points are printed on the bottom of the optical-grade acrylic sheet using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to all angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly. The purpose of the reflective sheet is to reflect the light exposed from the bottom back into the light guide plate to improve the efficiency of light use.

[0003] However, the composite light guide plate used in some existing technologies is usually fixed directly to the light guide plate body by screws when installed on the light-emitting frame; this fixing method is not only troublesome to install, but also causes the light guide plate to be damaged by the screws during the installation process, thereby affecting its service life.

[0038] The technical solution of the utility model is firstly to assemble the panel body 1 and the sliding assembly block 5 into one body, and then as the sliding assembly block 5 slides into the inner side of the assembly panel 2, the panel body 1 can be assembled into the light guide cavity 7, and the limiting effect of the assembly inner cavity 211 can improve the flexibility and convenience of assembly and improve the stability of the structural assembly; and through the limiting effect of the horizontal support plate 22 and the vertical support plate 21 and the light source board 4 irradiating the panel body 1 from the horizontal support plate 22, the stability of assembly and the fluency of use can be improved.

This structure can improve the stability of assembly and improve the safety of use. When disassembling, first remove the locking component 3, then push the elastic assembly part 6 to the bottom of the sliding inner cavity 214 through the push rod, move the sliding assembly block, so that the sliding assembly block 5 moves to the top of the elastic assembly part 6, and at the same time pull out the push rod; thereby, the elastic assembly part 6 is hidden and the panel body 1 is disassembled.
