Abstract

The invention discloses a heat dissipation method and device for a stage lamp and the stage lamp. A gravity sensor is arranged in the stage lamp and is used for judging and recognizing the change angle of a bulb and feeds back the information to an integrated circuit control panel, the integrated circuit control panel controls a motor to change the air direction of a fan, and then the heat of a bulb ball body can be uniformly dissipated. According to the heat dissipation method, the high heat dissipation requirement of high-power platinum cup bulbs can be met, the heat of bulb ball bodies can be dissipated uniformly, great temperature difference between the upper part and the lower part can be avoided, cold spots can be avoided, the use requirement of the bulb can be met, and the service life of the bulb can be prolonged.

Description

technical field [0001] The invention relates to the technical field of stage lighting, in particular to a heat dissipation method for a stage lamp, a heat dissipation device and a stage lamp. Background technique [0002] The high-power platinum bulbs with cups usually used in stage lamps have high heat dissipation requirements. The bulb sphere is required to dissipate heat evenly, and there should be no large temperature difference and cold spots between the upper and lower sides. For the platinum bubble cooling device used in stage lamps, the fan is usually fixedly installed and blows air at a fixed angle. Take a suitable angle to blow heat to the bulb sphere, but the stage lamp rotates 360 degrees, and the heat dissipation wind direction needs to change when the lamp rotates to different angles. . If the heat dissipation direction of the fan to the bulb is fixed, the heat dissipation of the bulb at different angles will be uneven, and cold spots will appear, which will a...
