Heat dissipation structure for air convection heat dissipation LED lamps

Abstract

The invention discloses an LED lamp heat radiation structure for air convection heat radiation. The LED lamp heat radiation structure comprises a mounting outer ring, springs, a fixed ring, a heat radiator, an optical device, an LED COB optical lens arranged at the bottom of the optical device, a wire buckle fixing sheet at the bottom of the heat radiator and a pull prevention fixed wire buckle arranged on the wire buckle fixing sheet. Due to the fact that a plurality of inner ring head radiation holes are formed in the fixed ring, a plurality of heat radiator heat radiation holes corresponding to the inner ring heat radiation holes are formed in the bottom of the heat radiator. In the use process, the inner ring heat radiation holes are matched with the heat radiator heat radiation holes, on the basis of the hot air rising principle, the friction force between the air and the surface of the heat radiator is increased through air convection formed by outside air, the heat radiator heat radiation holes and the inner ring heat radiation holes, and the heat radiation effect of the whole LED lamp can be improved. Meanwhile, compared with the heat radiation mode in the prior art, the structure further has the advantage of lowering heat radiation cost.

Description

【Technical field】 [0001] The invention relates to a heat dissipation structure of an LED lamp for air convection heat dissipation in the aspect of a lamp. 【Background technique】 [0002] Various LED lamps appear in the existing market. In order to ensure that the LED lamps can work normally, the heat dissipation structure of the LED lamp has become an indispensable LED component in the LED lamp. However, most of the existing heat dissipation structures of LED lamps include heat sinks, LED COB light source modules, optical devices, fixing rings and installation outer rings. When in use, the LED COB light source module is fixedly installed on the heat sink to form an LED light source heat dissipation part, the convex mirror or reflector of the optical device is covered with the COB light source, the fixing ring encloses the convex mirror or reflector of the optical device, and It is locked and fixed with the heat dissipation part of the LED light source by threads or screws t...

Problems solved by technology

Although this heat dissipation method can achieve the purpose of heat dissipation, the efficiency of heat dissipation is not high.

And because there are many heat dissipation components, the cost of heat dissipation is relatively high
