Down lamp with heat dissipation structure

Abstract

The invention discloses a down lamp with a heat dissipation structure. The down lamp comprises an annular lamp panel, a cylindrical lamp base and a lighting light source arranged in the cylindrical lamp base. A radiator connected with the lighting light source is arranged in the cylindrical lamp base, and the cylindrical lamp base is internally further provided with a small fan. The small fan is located above the radiator and fixed to the radiator through screws. A circular net plate is further arranged above the small fan, a clamping and fixing circular ring is further arranged above the circular net plate, and the outer diameter of the clamping and fixing circular ring is larger than the inner diameter of the cylindrical lamp base. The down lamp is reasonable in structure arrangement, the small fan is additionally arranged in the cylindrical lamp base, the circular net plate is further arranged above the small fan, accordingly, the heat dissipation performance of the cylindrical lampbase can be greatly improved, and therefore the power of the lighting light source can be greatly improved; and the integral usage stability of the down lamp can be better improved, the service lifeof the down lamp can be better prolonged, and the down lamp is high in applicability and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of lighting fixtures, and in particular relates to a downlight with a heat dissipation structure. Background technique [0002] With the maturity of my country's lighting technology, various downlights and spotlights have developed rapidly. The downlights of traditional technology are mainly composed of lamp holders and light sources fixed in the lamp holders. Although they can meet the use requirements to a certain extent, due to The space of the lamp holder is small, and the light source will generate a certain amount of heat when used, so it cannot be set as a high-power light source, because the heat cannot be dissipated in time, which will affect the stability and service life of the light source, applicability and practicality Sex is restricted. Contents of the invention [0003] The object of the present invention is to provide a downlight with a heat dissipation structure with reasonable structural ...
