Abstract

The invention discloses a tunnel lamp having a cooling effect. The tunnel lamp comprises a shell (2) which comprises a top cap (21) in threaded connection and a light-transmission bottom cap (22) with the cross section being in an arc shape. The middle of the top cap (21) is provided with a cooling groove (23) with a downward opening. The cooling groove (23) is provided with a cooling plate (3) for sealing the opening. The cooling plate (3) is provided with a circuit board (4) which is provided with an LED light source (5). The side wall of the cooling groove (23) is provided with a light reflection piece (6). The top cap (21) is further provided with a mounting rack (24). The tunnel lamp can automatically cool, and is large in irradiation range and suitable for lighting of a long, narrow and dark tunnel.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a tunnel lamp with heat dissipation effect. Background technique [0002] Tunnel lights are used in tunnels, workshops, large warehouses, venues, metallurgy and various factories, engineering construction, etc. With the rapid development of my country's road traffic construction, the construction scale and quantity of road tunnels are also increasing, and tunnel lighting has also emerged problems such as energy saving and safety that need to be solved. With the maturity of LED light source technology, domestic The lighting industry has also carried out research and application practice on the application of LEDs in road tunnel lighting. Chinese patent 201020582121 discloses an LED tunnel light, which includes a housing 1, a circuit board 2 inside the housing 1, an LED light source arranged on the circuit board 2, a reflector 4 arranged around the light source 3, and a The glass cover 5 belo...
