Description

Technical field [0001] The present invention involves a LED spotlight, especially a new type of LED digital spotlight. Background technique [0002] With the gradual maturity of LED technology, supplemented by modernization control technology, the use of LED spotlights in film and television performing arts, conferences, studios and other places is becoming increasingly widespread.However, from the analysis of the existing LED spotlight heat dissipation and focusing technology, manual focus is mainly used to achieve changes in the focal length of the lamp. Due to the manual scoring, the screw of the screw is used to drive the light source to move before and after, so as to achieve the adjustment of the focal length of the lamp. The operation is troublesome to operate., And inaccurate focus accuracy, cannot quickly and accurately meet the needs of realistic lighting.In terms of heat dissipation technology, with the development trend of the power power of LED lamps, LED lamps heat ...

AI Technical Summary

Problems solved by technology

However, from the analysis of the existing heat dissipation and focusing technology of LED spotlights, manual focusing is mainly used to realize the change of the focal length of the lamp. Since manual focusing uses a manual adjustment screw to push the light source forward and backward, so as to achieve the adjustment of the focal length of the lamp, it is troublesome to operate. , and the focusing accuracy is inaccurate, it cannot quickly and accurately meet the real lighting needs

In terms of heat dissipation technology, with the development trend of high-power LED lamps, heat dissipation of LED lamps has become the core technology that determines key indicators such as light decay and service life of lamps and lanterns. Mainly, the heat dissipation of the aluminum substrate is difficult to meet the heat dissipation requirements of high-power LED spotlights due to its limited thermal conductivity, while the heat dissipation of the duct is complicated in process, high in cost, and not very practical.
