Problems solved by technology

In the prior art, the general LED light source adopts a single-color temperature light source, but the single-color temperature light source can only be used in a single scene, and does not have the function of applying a LED spotlight to various occasions with different color temperature and brightness requirements. When the light source adopts multi-color temperature light source, there will be problems of spot effect and poor light mixing effect

Abstract

The invention relates to the technical field of lighting equipment, in particular to an LED spotlight with an adjustable lighting effect. The LED spotlight comprises a supporting frame, an LED light source and a secondary optical part, wherein the LED light source is a multi-color-temperature light source, and is arranged on the supporting frame; the secondary optical part is positioned in the light emitting direction of the LED light source, and is arranged on the supporting frame; the secondary optical part comprises a lens assembly and a focusing device used for adjusting the distance between lenses in the lens assembly; and the lens assembly comprises a collimating lens and a Fresnel lens, which are arranged in sequence in the light emitting direction. The LED spotlight with the adjustable lighting effect, provided by the invention, can be applied to occasions with different color temperature and brightness requirements, and has a better lighting effect.

Description

technical field [0001] The present invention relates to the technical field of lighting equipment, in particular to an LED spotlight, and more particularly to an LED spotlight with adjustable lighting effects. Background technique [0002] The green, energy-saving, and environment-friendly light-emitting diode (LED) application technology continues to penetrate into all aspects of society and life, bringing huge benefits to society in terms of energy saving, emission reduction, and creating a green life. In professional fields such as TV studios and live broadcast rooms, most of them still use traditional 2000W tungsten lamps, resulting in waste of energy and failing to achieve green and environmental protection effects. The main reason is that compared with the traditional 2000W tungsten lamp, the current LED spotlight still has a big gap in the illuminance, spot effect and color rendering index at a fixed distance. [0003] At present, outdoor interviews, TV studios and p...
