Problems solved by technology

However, only 20%-30% of the input power of high-power LED lamps is converted into light, and the rest of the power is released in the form of heat energy. For high-power LED lamps, the heat flux has reached 100W / cm 2 , without effective heat dissipation, the junction temperature will rise rapidly and the performance will degrade rapidly

Abstract

The invention discloses a radiator for radiating a lamp and a lamp provided with the radiator. The radiator comprises a heat conduction bottom plate for supporting a lamp circuit board and a helical fin taking the shape of a spiral, wherein a first connecting end of the helical fin is fixedly connected with the heat conduction bottom plate, and a second connecting end of the helical fin is provided with a connecting part connected with the lamp base of the lamp. When the radiator is used, the heat conduction bottom plate receives heat radiated by the lamp and rapidly conducts the heat to the helical fin, and the heat is transmitted upwards layer by layer via the helical fin and has convection with the air, so that the heat is conducted to the air. Therefore, the radiator, provided by the invention, radiates heat through the helical fin and the heat conduction bottom plate fixedly connected with each other, has greater radiating area and thermal conductivity, can keep excellent radiating efficiency, and can combine practicality and attractiveness.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a radiator and a lamp provided with the radiator. Background technique [0002] LED lighting fixtures are quickly popularized in the market due to their small size, low power consumption, environmental protection, durability, and rich light source colors. However, only 20%-30% of the input power of high-power LED lamps is converted into light, and the rest of the power is released in the form of heat energy. For high-power LED lamps, the heat flux has reached 100W / cm 2 , if there is no effective way to dissipate heat, the junction temperature will rise rapidly and the performance will drop rapidly. [0003] Therefore, how to dissipate heat from the lamp is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a radiator and a lamp provided with the radiator....
