Background
In order to meet market demands, the power of the current LED lamp is also higher, the heat dissipation lamp housing is usually manufactured by die casting, and the surface of the product is designed into a fin type to increase the heat dissipation area. But the heat dissipation lamp housing made in the die casting mode has high cost, and the subsequent processing technology is complex, so that the pressure of the manufacturing cost is increased. In addition, although the heat radiating area is increased by the fin type structure, as the heat accumulation of the lamp panel mounting position of the LED lamp is more, the heat is not intensively radiated at the position, and the final rapid heat radiation is not well achieved.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a lamp radiating structure which can effectively and rapidly radiate heat aiming at the mounting position of a lamp panel, and has the advantages of large radiating area and good radiating effect.

the radiating groove extends along the height direction of the radiating shell and comprises groove walls connected with the side walls of the radiating shell and groove holes positioned at two sides of the groove walls;
the heat dissipation grooves comprise a first heat dissipation groove and a second heat dissipation groove;

The upper end of the first heat dissipation groove extends to be close to the top of the heat dissipation shell, so that the proportion of the first heat dissipation groove to the heat dissipation shell is increased.
Further, the depth of the slot hole is 1-5mm. When the depth of the slot hole is too large, mosquitoes easily enter the heat dissipation cavity through the slot hole, and the connection between the slot wall and the heat dissipation shell is unstable; the depth of the slot hole is too small, so that a good heat dissipation effect cannot be achieved, and the strength and the heat dissipation effect can be achieved by the slot hole with the depth.
Further, the length of the first heat dissipation groove is S1, and the length of the second heat dissipation groove is S2, and S2/S1 is 0.3-0.7. The length of the first radiating groove and the length of the second radiating groove are reasonable in design, and good radiating effect can be achieved while the structural stability of the radiating shell is considered.
Further, the distance between the top end of the first heat dissipation groove and the top end of the heat dissipation shell is 1-4mm.

Further, the width of the first heat dissipation groove and the second heat dissipation groove is 4-10mm. The width design of the heat dissipation groove is reasonable, the structural strength and the heat dissipation effect are considered, and the stamping processing is convenient.
Further, the lamp panel assembly comprises a cover plate which extends along the radial direction of the heat dissipation shell, the outer ring is bent to form a flange which can be attached to the inner wall of the heat dissipation shell, and the lamp panel is assembled and connected with the cover plate. The heat emitted by the lamp panel work is quickly and uniformly conducted to the cover plate, the cover plate is conducted to one circle of the periphery of the heat dissipation shell through the flange, and then the heat is quickly conducted to the outside through the heat dissipation groove, so that the heat dissipation speed is high, and the heat dissipation effect is good.
