Description

Technical Field

[0001] The utility model belongs to the field of light guide plates, and particularly relates to a flat panel lamp with a high-transmittance LED light guide plate. Background Art

[0002] A light guide plate is made of optical-grade acrylic / PC plates, and then a high-tech material with extremely high reflectivity and no light absorption is used to print light guide points on the bottom surface of the optical-grade acrylic plate by UV screen printing technology. The optical-grade acrylic plate is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread in all directions, and then the reflection condition is destroyed and emitted from the front of the light guide plate. However, in the current light guide plate structure, some light sources do not enter the light guide plate, resulting in some light loss and thus low light efficiency. Summary of the Invention

A first installation groove 11 is provided in the middle of the bottom frame 10, the metal plate 20 is arranged at the bottom of the first installation groove 11, the light guide plate 30 is arranged above the metal plate 20, the light-transmitting panel 40 is arranged above the light guide plate 30, and a number of light guide points 31 are provided at the upper end of the light guide plate 30. Second installation grooves 12 are provided at both ends of the bottom frame 10, the LED light strip 50 is arranged in the second installation grooves 12, a number of LED lamp beads 51 are provided on the LED light strip 50, a number of first through holes 14 are provided at both ends of the bottom frame 10, and the first through holes 14 communicate the first installation groove 11 and the second installation grooves 12. The LED lamp beads 51 correspond to the first through holes 14 one by one, and the first through holes 14 correspond to the light guide plate 30. The LED light strip 50 controls the lighting of the LED lamp beads 51, and the light source enters the light guide plate 30 through the first through holes 14, is reflected by the light guide plate 30, diffuses out through the light guide points 31, and is illuminated through the light-transmitting panel 40. Moreover, the metal plate 20 can reflect the light source to avoid light source loss.

[0021] Furthermore, first hanging grooves 13 are provided at both ends of the bottom frame 10, the first hanging grooves 13 are L-shaped, a number of first hooks 32 are provided at the lower end of the light guide plate 30, the first hooks 32 correspond to the first hanging grooves 13 one by one, and a number of second through holes 21 are provided on the metal plate 20, and the second through holes 21 correspond to the first hooks 32 one by one. The metal plate 20 is arranged at the bottom of the first installation groove 11, and the light guide plate 30 is then arranged above the metal plate 20. By passing the first hooks 32 through the second through holes 21 and connecting them to the first hanging grooves 13, the light guide plate 30 and the metal plate 20 can be fixedly mounted on the bottom frame 10.
