Illumination lamp

Abstract

The invention provides an illumination lamp. The illumination lamp comprises a light splitting lens having an optical shaft, and a light source and a reflector arranged in the extending direction of the optical shaft in sequence, wherein a light mixing component is arranged between the light source and the light splitting lens; the optical shaft penetrates through the light mixing component; and emitting light of the light source is transmitted to the light splitting lens after being mixed by the light mixing component. As the light mixing component is arranged between the light source and the light splitting lens, the emitting light of the light source experiences once light homogenization before being emitted into the light splitting lens so as to obtain more collimated and uniform light distribution; and the illumination lamp has the characteristics of high optical efficiency, high center light intensity, low glare value and light spots with uniform light color. The illumination lamp can generate various light distribution rays with narrow, medium and wide light beams according to demands of illumination places.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED lighting fixture. Background technique [0002] At present, the use of LEDs in lighting fixtures has begun to be popularized. The requirements for the quality of light and color of LEDs are getting higher and higher in specific lighting surfaces, and the requirements for the distribution of light and color on the surface of the illuminated object are getting higher and higher, so as to meet the humanized needs of lighting. However, LEDs are characterized by 180° light emission, severe glare, and uneven transition of spot effects. In commercial lighting fields such as shops, art galleries, and conference rooms, narrow-angle beams are required, which requires LEDs to be designed with optical systems that focus beams.

AI Technical Summary

Problems solved by technology

However, LEDs emit light at 180°, severe glare, and uneven transition of spot effects. In commercial lighting fields such as shops, art galleries, and conference rooms, narrow-angle beams are required, which requires LEDs to be designed with optical systems that focus beams.

[0003] At present, the common light mixing technology is to use dense arrangement of LEDs and Fresnel lens. This technology requires concentrated arrangement of light sources, difficult to solve heat dissipation, and difficult to achieve optimized light distribution.

Another common technique is to use a collimating lens array with a pair of fly-eye lenses, which requires complex optical components and low optical efficiency
