Problems solved by technology

However, due to the addition of a fan, and the power consumption of high-power LEDs is already very large, turning on the fan for a long time will further increase power consumption, resulting in unnecessary waste
Therefore, the heat dissipation structure of the prior art still needs to be improved

Abstract

The invention relates to an LED (light emitting diode) projection lamp with a heat sink. The LED projection lamp with the heat sink comprises a front cover, a back cover, a light emitting unit, a heat dissipation part, a fan, a temperature detector and a control unit, wherein the heat dissipation part comprises a heat dissipation shell and fins; the fan is arranged in the back cover; the control unit can control the on and off of the fan according to the temperature of the light emitting unit. According to the heat sink arranged on the LED projection lamp disclosed by the invention, the heat dissipation effect of the projection lamp can be effectively improved, the service life of the projection lamp is prolonged, and the power consumption of the fan is saved.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED projection lamp with a cooling device and a control method thereof. Background technique [0002] With the maturity of LED technology, its application in daily life has become more and more extensive in recent years. Many traditional lamps have also begun to use LEDs as light-emitting units, among which LED spotlights are a common one. Due to the need for illuminance, the power of existing LEDs is increasing. High-power LEDs emit a lot of heat when they are working. If the heat cannot be taken away in time, the life of the LED will be damaged. Therefore, the heat dissipation structure is indispensable in LED spotlights, but most of the LED spotlights with existing structures only dissipate heat through the heat dissipation shell, and the LED drive circuit in the shell and the LED light-emitting unit can only be connected through the conduction mode of the heat dissipation shell. The...
