Efficient heat dissipation lamps

Abstract

An efficient heat dissipating lamp comprises a heat dissipating base, a supporting table body, a heat dissipating rotary wing plate assembly and LED illuminating bodies. The supporting table body is arranged on the heat dissipating base. A heat dissipating containing groove is formed in the side edge of the supporting table body. The heat dissipating rotary wing plate assembly comprises a rotary shaft and a plurality of rotary wing plates. The rotary shaft and all the rotary wing plates are all contained in the heat dissipating containing groove. The two ends of the rotary shaft are fixed to the two opposite inner side walls of the heat dissipating containing groove correspondingly. The rotary shaft rotates in sequence and penetrates through one ends of the rotary wing plates, and the rotary wing plates are arranged at intervals. When the efficient heat dissipating lamp is in the transportation process, all the rotary wing plates are contained in the heat dissipating containing groove, thus, the surface of the overall structure is more flat, the number of protruding structures is smaller, the efficient heat dissipating lamp is easy to store and package in a concentrated mode, limitation to packaging operation is smaller, when the efficient heat dissipating lamp needs to be used, the ends, away from the rotary shaft, of the rotary wing plates are made to stretch out of the heat dissipating containing groove, the thermal radiation effect and the thermal convection heat dissipation effect can be improved, and the heat dissipating performance is better.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a high-efficiency heat dissipation lamp. Background technique [0002] At present, a lamp refers to an appliance 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, and also need to install heat dissipation components to ensure proper cooling performance. [0003] However, in actual situations, in order to improve the heat dissipation performance of the heat dissipation component, especially in order to increase the heat dissipation surface area of ​​the heat dissipation component, usually, the heat dissipation component will be provided with sheet-shaped, prismatic, column-shaped or / and dot-shaped and other structures used to increase the heat dissipation surface area, alth...

Problems solved by technology

[0003] However, in actual situations, in order to improve the heat dissipation performance of the heat dissipation component, especially in order to increase the heat dissipation surface area of ​​the heat dissipation component, usually, the heat dissipation component will be provided with sheet-shaped, prismatic, column-shaped or / and dot-shaped and other structures used to increase the heat dissipation surface area, although these structures can better improve the heat dissipation surface area of ​​the heat dissipation components, but due to these protruding structures, there are more discontinuous surfaces, that is, the overall surface is not smooth enough, and the , these protruding structures will generate large local stress on the packaging structure, which is easy to cause its own bending, and also easy to cause problems such as depressions in the corresponding areas of the packaging structure, and because the surface is not smooth enough, it will cost more packaging Material, that is to say, existing heat dissipation components due to the unevenness of the surface of the overall structure during packaging and transportation, thereby increasing the restrictions on packaging operations
