Description

technical field [0001] The invention relates to an LED projection lamp, in particular to a high-power LED projection lamp utilizing liquid cooling for heat dissipation. Background technique [0002] Existing light sources are mainly used for lighting, but with the evolution of the times, they are gradually endowed with different life, such as the backlight display of the screen or the colorful light effect of the stage, all of which have changed from the past that the light source can only be used as lighting Stereotype; however, the previous light source has the disadvantages of large size, power consumption and not long service life, so that users have to replace the light source every once in a while, and the power consumption of the light source also makes users love and hate it. In addition, due to the volume problem, it needs to take up a lot of space in use. These shortcomings either limit the use of light sources or increase the burden on the use of light sources; ho...

[0002] Existing light sources are mainly used for lighting, but with the evolution of the times, they are gradually endowed with different life, such as the backlight display of the screen or the colorful light effect of the stage, all of which have changed from the past that the light source can only be used as lighting Stereotype; however, the previous light source has the disadvantages of large size, power consumption and not long service life, so that users have to replace the light source every once in a while, and the power consumption of the light source also makes users love and hate it. In addition, due to the volume problem, it needs to take up a lot of space in use. These shortcomings either limit the use of light sources or increase the burden on the use of light sources; however, since the appearance of LEDLight-Emitting Diode, it has greatly changed. The impression of the light source in the past, because the LED has the advantages of small size, power saving and long service life, it completely subverts the shortcomings of the light source used in the past. Therefore, in today's society, LED has been widely used

[0003] Due to the evolution of technology, today's LED has developed into a grain type, making the LED smaller, thinner and more energy-saving; however, although the current LED has many advantages as a light source, there is still a fatal shortcoming , is the heat dissipation problem

If you use several LEDs, you only need to use cooling fins to achieve the purpose of heat dissipation. However, if you use LEDs in places such as display walls or large light sources such as stage lights, the number of LEDs required is often hundreds or even Tens of thousands, the heat generated by it can no longer be handled by the cooling fins. However, if the heat is not properly handled, it will cause the LED to overheat and burn out.

[0004] In addition, general heat dissipation methods, such as using heat dissipation fins and attaching heat dissipation fins to several LED dies, will undoubtedly increase the volume and hinder the appearance. In addition, heat dissipation fins can only be used on the back of the LED, otherwise It will affect the luminescence. These problems also point to the problems of the heat dissipation technology used in the past.
