Description

A water-cooling heat dissipation system for stage lamps and lanterns

technical field

The utility model mainly relates to the technical field of heat dissipation of stage lamps, and more specifically relates to a water-cooling heat dissipation system for stage lamps.

Background technique

In the field of stage lighting, people often need to use high-power stage lights to enhance the lighting effect, shooting effect and stage effect of the stage. However, while the brightness of high-power stage lights increases, the heat generated also increases greatly. Especially for the light source part of the stage light, if the heat generated for a long time is too large and the temperature is too high, it will affect the service life of the stage light.

For example, the stage lights that use LED as the light source, this kind of light source is restricted by the technical characteristics of the light source during operation, can only convert a small part of the electric energy into visible light, and most of the electric energy is converted into heat, infrared rays, ultraviolet rays and other forms of consumption , so that a lot of heat is often generated during work, so that the temperature of the light source is too high, which in turn affects the use effect of the lamp and the service life of the light source. Therefore, it is necessary to dissipate heat and cool the light source part of the stage lamp.

In the prior art, holes are usually made in the shell of the stage lamp, and the heat is exported through a metal radiator arranged on the light source, and then a fan is used to force the heat out of the lamp. This heat dissipation method belongs to air-cooled heat dissipation, because air-cooled heat dissipation is forced to discharge heat from the outside of the lamp during the working process, so the air-cooled radiators that need to be used also have high power, high consumption, large volume, multiple heat pipes, ultra- weight etc. Therefore, the power consumption and the use environment of the stage light source are limited, and the lamp is too large and heavy, which also brings great inconvenience to users in the actual use and installation of the stage light.

In order to overcome at least one defect described in the above-mentioned prior art, the utility model provides a water-cooling heat dissipation system for stage lamps.
