The utility model will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, the present embodiment provides an LED tunnel lamp, which includes a lamp body and a lighting assembly fixedly mounted on the lamp body.

The lamp body comprises a lamp body 11 and a heat sink 12, wherein the lamp body is integrally formed by die casting, and the heat sink is formed by extrusion molding of an aluminum profile. The lamp body 11 is a flat structure having a front surface and a back surface which are oppositely arranged, and the light emitting component in the lighting component 2 is fixedly assembled on the front surface of the lamp body 11. In this embodiment, a cavity is formed in the front surface of the lamp main body 11, a light-transmitting panel 21 covers an opening of the cavity, the light-transmitting panel 21 seals the cavity through a sealing ring 22, a circuit board 23 attached with a plurality of LED beads and a lens assembly 24 located on the light emitting side of the circuit board 23 are fixedly mounted in the cavity, and light emitted by the LED beads on the circuit board 23 is emitted from the light-transmitting panel 21 after being distributed by the lens assembly 24 to illuminate. In this embodiment, still fixed mounting has drive power supply 25 on the back of lamps and lanterns main part 11, and drive power supply 25 is connected the setting with LED lamp pearl electricity.

The back of the lamp main body 11 is provided with a fixing surface 110 for fixedly mounting the radiator 12, the radiator 12 comprises a tabular radiator body 120, the front surface of the radiator body 120 is matched with the fixing surface 110, so that the radiator body 120 can be attached to the fixing surface 110, in the embodiment, in order to ensure the attaching tightness between the lamp main body 11 and the radiator 12, the contact surface of the lamp main body is uniformly coated with heat-conducting silicone grease, so as to achieve the best attaching state, and ensure the best heat dissipation channel to realize good heat dissipation effect.

The back surface of the heat sink body 120 is provided with a plurality of heat dissipation fins 121 formed by extrusion molding together with the heat sink body 120, so that the heat sink 12 has good heat dissipation capability.
