技术领域technical field
本实用新型涉及照明设备技术领域，尤其涉及一种LED聚光灯，更具体地涉及一种照明效果可调的LED聚光灯。The utility model relates to the technical field of lighting equipment, in particular to an LED spotlight, and more particularly to an LED spotlight with adjustable lighting effect.
背景技术Background technique
绿色、节能、环保的发光二极管LED应用技术不断深入到社会及生活的方方面面，给社会节能减排、创造绿色生活带来了巨大的效益。在电视台的演播室、直播间等专业领域，绝大多数还是停留在使用传统的2000W钨丝灯的阶段，造成能源的浪费，不能达到绿色、环保的效果。其主要原因是目前的LED聚光灯与传统2000W钨丝灯相比，其固定距离的照度、光斑效果及显色指数还有很大差距。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.
目前，室外采访、电视台演播室和产品宣传照片拍摄场地均需要采用LED聚光灯提高灯光效果，灯具分别是面光源的平板LED灯具及简单二次光学可调焦距的LED聚光灯。现有技术中，一般LED光源采用单色温光源，但是，单色温光源只能进行单一场景的使用，不具备一种LED聚光灯应用于多种不同色温及亮度需求场合的功能，而当LED光源采用多色温光源时，又会出现光斑效果及混光效果不好的问题。At present, outdoor interviews, TV studios and product promotion photo shooting sites all need to use LED spotlights to improve lighting effects. The lamps are flat-panel LED lamps with surface light sources and LED spotlights with simple secondary optical adjustable focus. 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 poor light spot effect and light mixing effect.
