Description

A multifunctional LED illuminator

technical field

The utility model relates to an LED illuminator, in particular to a multifunctional LED illuminator capable of simultaneously adjusting color temperature, color rendering and color conversion.

Background technique

Light Emitting Diode (LED: Light Emitting Diode) is a semiconductor optoelectronic device that has risen rapidly in recent years. It has the advantages of small size, light weight, power saving, long life, high brightness and fast response to light emission. It is easy to integrate with transistors and integrated circuits. Supporting the use of. With the continuous improvement of chip luminous efficiency, LED has also been applied to a certain extent in the field of general lighting. Compared with conventional lighting sources such as fluorescent lamps and incandescent lamps, LED illuminators can realize not only white light lighting, but also colored lighting by matching red, green and blue colored LED chips. In addition, for white LEDs, the luminous efficacy and color rendering are high at high color temperature, but the color rendering is poor at low color temperature, and the color deviates from the requirements of general lighting. By adding red and green LED chips, in addition to realizing colored lighting, the color rendering of the light source can be improved and the color temperature of the light source can be adjusted through the color mixing of red, green and white light. Realize the lighting effects that ordinary light sources or pure white LED light sources cannot achieve.
