Abstract

The invention provides a large-power LED spotlight characterized by active heat dissipation and belongs to the field of lamps. A lamp holder is fixed on a lower cover; a power drive temperature control plate, a fan, a heat dissipation device, and LED light source, a light source pressing plate, reflective paper, a lens and an upper cover are successively and fixedly connected in a cone from bottom to top; the fan is electrically connected with the power drive temperature control plate, and the LED light source is electrically connected with the power drive temperature control plate; gaps are left between the power drive temperature control plate, the fan and the heat dissipation device, which are fixed on the lower cover via screws; the light source is arranged under the light source pressing plate which is fixed on a heat sink via screws; the reflective paper and the lens are arranged under the upper cover; the upper cover is connected with the heat dissipation device. The structure of the large-power LED spotlight is improved; the wind resistance is reduced and a heat dissipation air duct is unblocked; the manufacture process is simplified, the manufacture cost is reduced and the service life is prolonged.

Description

technical field [0001] The invention relates to a high-power LED spotlight, in particular to an active heat dissipation high-power LED spotlight, which belongs to the field of lamps. Background technique [0002] The rise of the LED lighting industry in the 21st century has become an indisputable fact. In the field of commercial lighting such as shopping malls and warehousing, with the further reduction of LED lighting costs, the field of household lighting will begin to grow on a large scale, and indoor lighting will be the fastest growing market in the future. [0003] At present, LED spotlights in indoor lighting, one adopts active heat dissipation, and the other adopts passive heat dissipation. Passive heat dissipation spotlights mainly use all-metal shells made of aluminum extruded or stamped. Poor convection, the temperature rises in a short time, which is not conducive to heat dissipation, and it is difficult to realize high-power lamps. And the shell temperature is...
