Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and 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 connection seat, a plurality of heat sinks are fixedly installed on the top of the connection seat, two connection plugs are symmetrically installed on the left and bottom of the connection seat, and a connection slot for use with the connection plug is provided at the right and top of the connection seat corresponding to the connection plug, and a transmission cavity is provided between the two connection slots on the same side; a connection positioning mechanism is installed at the position corresponding to the transmission cavity on the connection seat. The heat dissipation structure of this lamp is formed by setting a plurality of upright heat sinks. The heat dissipation area of ​​this heat dissipation structure is limited, and the heat dissipation effect needs to be improved. In addition, the wind needs to follow the air duct between the heat sinks to effectively dissipate heat. When the wind flows from the side, most of it is blocked by the first heat sink, and an efficient heat dissipation air duct cannot be formed, thereby greatly reducing the heat dissipation effect of the remaining heat sinks. 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 includes a shell and a heat sink arranged on the back of the shell, and is characterized in that the heat sink is provided with multiple rows of upwardly protruding heat dissipation units, each row of heat dissipation units includes a plurality of heat dissipation blocks arranged in a left-right staggered manner in sequence, and an air duct is formed between adjacent heat dissipation units.

[0006] Furthermore, longitudinal through holes are provided at both longitudinal ends of the heat dissipation block, and the longitudinal through holes of every two upper and lower adjacent heat dissipation blocks are staggered and aligned.

[0007] Furthermore, the heat sink is a whole-piece structure, and the heat sink block and the longitudinal through hole are formed by the heat sink protruding upward.

[0008] Furthermore, the heat dissipation blocks of each column of the heat dissipation units are sequentially connected or arranged at equal intervals.

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

[0010] After adopting the above technical solution, the staggered setting of the heat dissipation block 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, with better heat dissipation effect, while also reducing light decay and extending the service life of the lamp.
