Description

Technical Field

[0001] The utility model relates to the field of stage lighting equipment, in particular to a stage lamp with a novel heat dissipation device. Background Art

[0002] With the continuous innovation and progress of stage lighting technology, high-power stage lights have been widely used in theaters, concerts, TV broadcasts, etc. due to their high brightness, rich colors, strong adjustability, etc. However, high-power stage lights will generate a lot of heat during operation. This is because when the light source inside the lamp (such as LED, halogen lamp, etc.) works at high intensity, it will convert electrical energy into light energy and also generate a lot of heat energy.

[0003] If this heat cannot be dissipated in a timely and effective manner, it will cause the temperature inside the lamp to rise, which will have a negative impact on the electrical components and optical system of the lamp. Specifically, high temperature will accelerate the aging of electronic components and reduce their service life; at the same time, excessive temperature will also affect the performance of optical components, such as causing lens deformation, reflector cup shedding and other problems, thereby reducing the brightness, color and beam distribution of the lamp. More seriously, if poor heat dissipation causes the temperature inside the lamp to continue to rise, it may also cause safety accidents such as fire, causing huge losses to people and property.

[0004] In order to solve the heat dissipation problem of high-power stage lights, the traditional approach mainly relies on fans and heat sinks for heat dissipation. Fans take away heat by forced convection, while heat sinks speed up heat dissipation by increasing the heat dissipation area. However, in the application of high-power stage lights, traditional heat dissipation methods have the following shortcomings:

[0005] Fan cooling is limited by environmental conditions and the performance of the fan itself. When the ambient temperature is high or the fan fails, the cooling effect will be greatly reduced.

[0006] Although the heat sink can increase the heat dissipation area, its heat dissipation effect is limited in a limited space, and too many heat sinks will increase the weight and volume of the lamp, affecting the installation and use of the lamp.

[0007] Fans and heat sinks will generate noise and vibration during long-term operation, affecting the acoustic and visual effects of the stage. Utility Model Content

[0059] Working principle of heat dissipation device

[0060] The heat dissipation device includes a first heat sink and a second heat sink, which respectively dissipate heat from the lamp body 3 and the inside of the housing 1 .

[0062] The pump body 14 is connected to the heat pipe 13 , and drives the liquid metal to circulate in the heat pipe 13 , so as to quickly conduct the heat to other parts of the radiator for heat dissipation, thereby maintaining the internal temperature of the lamp body 3 stable.

[0063] The second radiator is arranged at the bottom of the machine box 1 and can adopt a heat sink, a fan or other heat dissipation elements to dissipate the heat generated by the operation of the power supply, the controller and other components inside the machine box 1.
