referring to fig. 1-10, a tunnel lamp radiator includes a heat conduction substrate 1 for installing a light-emitting lamp panel, the heat conduction substrate 1 is provided with a plurality of radiating fins 2 on the opposite side of the light-emitting lamp panel relative to the installation, and a gap is provided between adjacent radiating fins 2, so that air can directly pass through the radiating fins 2, and heat is easily taken away.

The outer surface of the radiating fin 2 is provided with a serrated radiating protrusion 21. The contact area between the radiator and the outside air is enlarged by the zigzag radiating protrusions 21, the surface area of the radiating fins is increased by more than 1 time compared with that of the radiating fins 2 which are originally straight surfaces, and the heat of the LED lamp panel can be rapidly dissipated. The heat dissipation protrusions 21 are in the shape of a parallelogram. The principle that the length of the bevel edge is larger than that of the right-angle edge is utilized, the contact area between the radiator and the outside air is further increased, and the effect of rapid heat dissipation is achieved. The heat dissipation notches 22 are formed between the adjacent heat dissipation protrusions 21, and the opening directions of the heat dissipation notches 22 are inclined outwards, so that air flow can smoothly pass through the heat dissipation notches, and the heat dissipation effect is good.
