Problems solved by technology

However, the LED light source of the LED strip-shaped decorative light-emitting board faces the light guide plate, and the direction in which the light from the LED light source is emitted is the same as the light guide direction of the light guide plate. Therefore, the LED light source can only be connected to a heat sink on one side to dissipate heat. The heat conduction is slow and the spatial arrangement of lighting devices is not well utilized to achieve better heat dissipation

Abstract

The invention discloses a lighting device. The lighting device comprises a light source support piece, a first shell and a second shell, wherein the second shell isdetachably assembled with the first shell, the first shell is connected with external space at the upper part ofa lighting device body, the light source support piece is connected with external space at the lower part of the lighting device body, a first surface of the light source support piece is connected with the first shell, a second surface of the light source support piece is connected with the second shell, and the first shelland the second shell are made of the heat dissipation materials, so that the heat is respectively dissipated from the first surface and the second surface of a light source plate through the first shell and the second shell.

Description

【Technical field】 [0001] The invention relates to a lighting device. 【Background technique】 [0002] As LED light sources are more and more applied to lighting equipment, the design of lighting devices has more possibilities. Chinese Patent No. CN201513803 discloses an LED strip-shaped decorative light-emitting board, which is composed of a strip-shaped lamp holder, a light guide plate, a circuit board and an LED lamp. However, the LED light source of the LED strip-shaped decorative light-emitting board faces the light guide plate, and the direction in which the light from the LED light source is emitted is the same as the light guide direction of the light guide plate. Therefore, the LED light source can only be connected to a heat sink on one side to dissipate heat. The heat conduction is slow and the spatial arrangement of the lighting device is not well utilized to achieve better heat dissipation. [0003] Therefore, in order to overcome the above defects, it is necess...
