Heat dissipation device of lamp

Abstract

The invention discloses a heat dissipation device of a lamp, relates to the technical field of lamp use and heat dissipation, and aims to solve the problems that a light-emitting source generates a large amount of heat as time goes on when an existing lighting lamp is used, if the heat is not dissipated in time, the service life of the whole lighting lamp is shortened, and unnecessary economic losses are brought to users. A lampshade is arranged at one end of a lighting lamp, a lamp body is arranged on one side of the lampshade, a lamp slotted rear cover is arranged on one side of the lamp body, a plurality of heat dissipation slotted holes are formed in the outer wall of the lamp slotted rear cover, and an external exhaust fan is arranged on one side of the lamp slotted rear cover. A plurality of exhaust fan air outlet holes are formed in the outer wall of the external exhaust fan, and four exhaust fan fixing blocks are arranged on the outer wall of the external exhaust fan.

Description

technical field [0001] The invention relates to the technical field of lamp use and heat dissipation, in particular to a heat dissipation device for a lamp. Background technique [0002] Lamps refer to appliances that can transmit light, distribute and change the light distribution of the light source, including all parts required to fix and protect the light source except the light source, as well as the necessary line accessories for connection to the power supply. There are many types of lighting fixtures , There are chandeliers, ceiling lamps, table lamps, floor lamps, wall lamps, spotlights, etc. However, when the existing lighting fixtures are in use, their light sources will generate a lot of heat as time goes by. If the heat is not dissipated in time, the service life of the entire lighting fixture will be reduced and unnecessary economic losses will be brought to the user. Therefore, it does not meet the existing needs, and we propose a heat dissipation device for ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a heat dissipation device for lamps, so as to solve the problem that the light-emitting source of the existing lighting lamps proposed in the above-mentioned background technology will generate a large amount of heat as time goes by. If the heat is not dissipated in time, It will reduce the service life of the entire lighting fixture and bring unnecessary economic losses to users
