Abstract

A light emitting diode (LED) light source device comprises a lampshade (1), a base (2), a light source assembly (3), a radiator (4), end covers (5), and a plurality of heat-conducting connecting pieces (6). The lampshade (1) is a shell structure with two open ends and comprises a light transmitting part (11) and a mounting part (12); the light source assembly (3) is mounted on a mounting face of the base (2), another mounting face of the base (2) is attached to the inner wall of the mounting part (12), and the base (2) and the light source assembly (3) are mounted in the lampshade (1); a mounting face of the radiator (4) is attached to the outer wall of the mounting part (12); the radiator (4) has a groove (41) for holding a driving power supply (7) of the LED light source device, and a lead of the driving power supply (7) is connected with a lead of the light source assembly (3); the mounting part (12) of the lampshade (1) is opened with mounting holes (121); the plurality of heat-conducting connecting pieces (6) penetrates through the mounting holes (121) to connect the radiator (4) with the base (2); and the end covers (5) cover two ends of the lampshade (1) to seal the lampshade (1). In the LED light source device, water or dust can be prevented from entering the lampshade (1), and the lead of the driving power supply (7) is directly connected with the lead of the light source assembly (3), so that the service life of the LED light source device can be prolonged.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an LED light source device. Background technique [0002] At present, light-emitting diode (Light Emitting Diode, LED) light source devices have been widely used in home lighting and outdoor decorative lighting. It is an inevitable trend for LED light source devices to replace existing ordinary incandescent tube lamps as lighting appliances. [0003] The existing LED light source device includes a lamp holder, a light source board, a radiator and a semi-tubular lampshade. The lengths of the lampshade, the light source board and the radiator are basically the same. sheet to increase the heat dissipation area and improve heat dissipation efficiency. [0004] When assembling, the light source board is fixedly connected on the installation plane of the radiator, the lampshade is covered on the light source board, and the two ends of the radiator and the lampshade are fixedly installed in t...
