Problems solved by technology

[0002] At present, the mature blue light excites yellow phosphor to produce white light technology, which has greatly improved the light efficiency and color rendering of white LEDs, but there is still a big gap compared with full-spectrum natural light, and the spectrum lacks 490-500nm. The blue-green light part and the red light part of 650-700nm, and the beam of the white LED is narrow, the blue light band is relatively concentrated, and the phenomenon of "rich blue" is serious. Long-term use will cause blue light harm to the human body. This problem needs to be improved urgently

Abstract

The invention provides a full-spectrum LED lighting source, and belongs to the technical field of LED light sources. In order to solve the problem that in the prior art, a white LED is rich in blue, the full-spectrum LED lighting source comprises an LED array light source, a radiator, a lampshade, an LED circuit control system and a power supply switch controller. The LED array light source comprises an LED blue and green light source, an LED red light source and an LED white light source, wherein no fluorescent powder is added into the LED blue and green light source and the LED red light source, and chips of the LED blue and green light source and the LED red light source are luminous. The LED blue and green light source, the LED red light source and the LED white light source are arranged in concentric circles, the spectrums of the full-spectrum LED lighting system are close to the spectrums of sunlight, the spectrum continuity is high, and the color rendering performance is high.

Description

technical field [0001] The patent of the present invention relates to the technical field of LED light sources, in particular to a full-spectrum LED lighting source. Background technique [0002] At present, the mature blue light excites yellow phosphor powder to produce white light technology, which has greatly improved the light efficiency and color rendering of white LEDs, but there is still a big gap compared with full-spectrum natural light, and the spectrum lacks 490-500nm. The blue-green light part and the red light part of 650-700nm, and the beam of the white LED is narrow, the blue light band is relatively concentrated, and the phenomenon of "rich blue" is serious. Long-term use will cause blue light harm to the human body. This problem needs to be improved urgently. Contents of the invention [0003] The object of the present invention is to propose a full-spectrum LED lighting source, the spectrum of the LED lighting source is close to the sunlight spectrum, and...
