AI Technical Summary

Problems solved by technology

Tunnel lights are hung in the tunnel for a long time. Under the erosion of dust and moisture, if the sealing is not good, the tunnel lights are very prone to aging or damage
At present, the driving structure of the tunnel light is installed behind the lamp body, and a separate seal is required to seal the driving structure, which increases the cost of the tunnel light

Embodiment Construction

[0029] see figure 1 and figure 2 , the tunnel light 100 of this embodiment includes a lamp holder 110 , an LED assembly 120 , a heat sink 130 , a driver 140 , a reflector 150 , a lampshade 160 and a bracket 170 .

[0030] The lamp holder 110 is provided with a receiving groove (not shown). The lamp holder 110 includes a bottom 111 , a side wall 112 , a boss 113 , an internally threaded blind hole 114 , a hook 115 , a through hole 116 , a wire sealing sleeve 117 and a connecting portion 118 .

[0031] see image 3 , the bottom 111 is provided with a boss 113, the boss 113 is provided with an internal thread blind hole 114, the opening of the internal thread blind hole 114 faces the inside of the lamp holder 110, and the bottom 111 is a fully sealed structure, which avoids the need for installation. The through hole destroys the sealing effect of the lamp holder 110.

[0032] see Figure 4 and Figure 5 , the hook 115 is disposed on one side of the side wall 112 . The si...

Abstract

A tunnel lamp comprises a lampholder, a plurality of LED (light emitting diode) assemblies, a heat dissipation unit and a driving unit. Every LED assembly comprises an LED light source and a substrate which are electrically connected; the heat dissipation unit comprises a U-shaped main body and two lugs formed by bending outwards and extending both ends of the U-shaped main body, the U-shaped main body is provided with a step portion, the LED assemblies are connected to the step portion, the two lugs are fixedly connected with the lampholder to invert the U-shaped main body onto the bottom of the lampholder, and the heat dissipation unit and the bottom of the lampholder form an accommodating hole together; the driving unit is accommodated inside the accommodating hole. The bottom of the U-shaped main body is in a step shape, the plurality of LED assemblies are arranged on the outer side and the opposite two sides of the bottom of the U-shaped main body respectively, the driving unit is arranged between the bottom of the lampholder and the U-shaped main body, fixedly connected with the bottom of the lampholder and accommodated inside the tunnel lamp, so that other sealing units for sealing the driving unit can be omitted. The tunnel lamp is easy to mount, saves labor and material resources and reduces the cost of the tunnel lamp.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a tunnel lamp. 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. Tunnel lights are hung in the tunnel for a long time. Under the erosion of dust and moisture, if the sealing is not good, the tunnel lights are very prone to aging or damage. At present, the driving structure of the tunnel light is installed behind the lamp body, and a separate seali...
