Technical Field

[0001] The utility model relates to the technical field of LED light guide plates, in particular to an LED light guide plate with a limiting mechanism. Background Art

[0002] LED light guide plates are made of optical-grade acrylic and utilize LCD display and backlight module technology. Through the full high transmittance of the light guide points, the light guide points are designed by computer to convert the light of the light guide plate into a uniform light source state.

[0003] However, when installing the existing LED light guide plate, since the light guide plate itself does not have a limiting mechanism, the light guide plate needs to be placed in the correct position and then fixed with bolts. The operation is tedious, complicated, time-consuming and labor-intensive. Utility Model Content
