a led spotlight

Abstract

The invention relates to an LED spot lamp which comprises a supporting frame, an LED light source arranged on the supporting frame, and a secondary optical portion arranged on the supporting frame and positioned in the direction of the emergent light of the LED light source. The secondary optical portion comprises at least two lenses and a focusing device used for adjusting the distance between the lenses. The distance between the two lenses is adjusted through the focusing device to realize the illuminance and light spot effect at a fixed distance away from a lamp body to meet lighting needs of different scenes. By optimizing design of the LED light source, the illuminance and the light spot effect of the LED spot lamp is further adjusted, and color rendering index of the LED light source can be improved; by optimizing heat-conducting and heat-radiating design, the heat-radiating effect of the LED spot lamp is improved, and energy of the LED spot lamp can be saved by more than 80%; by lowering heat productivity of a product, energy consumption of air conditioning systems in a studio and a direct broadcasting room is indirectly reduced, and environment-friendly social demonstration effect is realized while high economic benefit is brought.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an LED spotlight. 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, there are a very small number of LED lamps entering TV studios and live broadcast rooms, which are flat-panel LED lamps with surface light s...

AI Technical Summary

Problems solved by technology

Flat-panel LED lamps with surface light sources cannot be widely used in TV studios and live broadcast rooms due to their single optical effect and insufficient illumination.

In addition, the LED spotlight with simple secondary optics and adjustable focal length only has a secondary optical processing link composed of threaded lenses in front of the LED light source, resulting in large optical loss, and the illuminance, spot effect and color rendering index at a fixed distance cannot reach The level of traditional 2000W tungsten lamp
