Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a heat dissipation structure of a lamp. Background Art

[0002] Lighting fixtures generate a lot of heat when working. The higher the temperature, the shorter the service life of the lamp. Therefore, the heat dissipation problem of LED lighting fixtures is very important. For example, the Chinese utility model patent with application number 202320627409.0 discloses a split LED vehicle lamp radiator, including a connecting seat, a plurality of heat sinks are fixedly installed on the top of the connecting seat, two connecting plugs are symmetrically installed on the left and bottom of the connecting seat, and the right and top of the connecting seat are provided with connecting slots for use with the connecting plugs, and a transmission cavity is provided between the two connecting slots on the same side; a connection positioning mechanism is installed on the connecting seat at a position corresponding to the transmission cavity. The heat dissipation structure of this lamp is formed by setting a plurality of upright flaky heat sinks. The heat dissipation area of ​​this heat dissipation structure is limited, and the heat dissipation effect needs to be improved. Summary of the invention

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a lamp heat dissipation structure with better heat dissipation effect.

[0004] To this end, the utility model is implemented by adopting the following technical solutions:

[0005] The heat dissipation structure of the lamp comprises a shell and a heat sink arranged on the back of the shell, and is characterized in that the heat sink is provided with a plurality of upward wavy convex strips, and a first air duct is formed between adjacent wavy convex strips.

[0006] Furthermore, the wavy convex strip is provided with heat dissipation holes along its length direction, and the heat dissipation holes form a second air duct.

[0007] Furthermore, the heat sink is a whole-piece structure, and the wavy convex strips and heat dissipation holes are formed by the heat sink protruding upwards.

[0008] Furthermore, the plurality of wavy convex strips are distributed at equal intervals.

[0009] Furthermore, the heat sink is bonded to the shell by glue.

[0010] After adopting the above technical solution, the setting of the wavy convex strips greatly increases its contact area with the air and wind flow, so that the heat dissipation structure can quickly dissipate the heat generated by the light source to achieve rapid cooling of the light source, better heat dissipation effect, and also reduce light decay and extend the service life of the lamp.
