Abstract

A LED light comprises a baseplate, a control panel electrically connected with the baseplate, a lampshade connected with the baseplate and a radiator, wherein the radiator comprises a base, heat transferring tubes connected with the base and cooling fins connected with the heat transferring tubes; a binding head is arranged at one end of the base with the end away from the baseplate; a groove is formed in one side of the base with heat transferring tubes connected on the side; a rotating loop is arranged in the groove; bumping posts bulging towards cooling fins are arranged on the rotating loop; an electric motor is arranged in the base; the electric motor is connected with the rotating loop to drive the rotating loop to rotate; straight sliding grooves are formed in the outer edges of the heat transferring tubes; the cooling fins adopt elastic sheetmetal and are provided with first clamping parts; the first clamping parts are arranged in the sliding grooves and can slide along the sliding grooves. According to the LED light, when the cooling fins are at the opening state due to elasticity a plurality of cooling fins facilitate heat dissipation; the electric motor can cause the cooling fins to bend, so as to shrink the LED light to decrease the size.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lamp. Background technique [0002] LED lights have the characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the heat dissipation and safety issues of LED lights are also key issues. Traditional LED lamps have a good heat dissipation effect because of their large heat dissipation area, which helps to improve the service life of LED lamps, but large radiators are not conducive to the transportation and storage of LED lamps. Contents of the invention [0003] Based on this, it is necessary to provide an LED lamp with higher heat dissipation efficiency and convenient storage. [0004] The LED lamp includes: a base plate, a control board electrically connected with the base plate and a radiator connected with the base plate. [0005] The radiator includes a base, a heat transfer tube connec...
