Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] In order to solve the deficiencies in the prior art, such as lack of spectral distribution, excessive concentration of blue light energy, unfavorable eyesight health of students, and low circadian rhythm factor, the present invention provides a method for realizing light with low blue light hazard and high circadian rhythm factor. And a LED light source with low blue light hazard and high circadian rhythm factor. The light obtained by the method and the LED of the present invention can not only reduce visual fatigue, but also reduce the harm of blue light, and can also adjust circadian rhythm factors, improve students' attention, and enhance learning efficiency.

[0032] In the method for realizing light with low blue light hazard and high circadian rhythm factor in the present invention, the blue light chip 31 and the purple light chip...

Abstract

The invention relates to a method for realizing the low blue light hazard and high circadian rhythm factor light, and an LED light source. The method is advantaged in that the yellow phosphor and thegreen phosphor are excited by a blue chip and a violet chip of different main wavelength ranges to form the light. The method is advantaged in that the obtained light can not only reduce visual fatigue, but also reduce the blue light hazard, can further adjust the circadian rhythm factor, improve students' attention and enhance learning efficiency. According to the method described above, the LEDlight source can form the light with the low blue light hazard and the high circadian rhythm factor in the optical theory, in the structural process, the yellow phosphor, the green phosphor and the encapsulant are mixed, and uniformly coated on surfaces of the blue chip and the violet chip through the centrifugal process to uniformly excite the phosphor, a cup wall of a reflector cup is plated with silver, light reflection is improved, and the light output rate is improved.

Description

technical field [0001] The present invention relates to the field of lighting, more specifically, to a method for realizing light with low blue light hazard and high circadian rhythm factor, and an LED light source with low blue light hazard and high circadian rhythm factor. Background technique [0002] At present, more and more schools use LED light sources and LED lamps as teaching lighting. However, the common LED light source mostly uses a single blue light chip to excite yellow phosphor to form white light, the spectral distribution is missing, which is far from natural light, and the energy of the blue light is too concentrated, and it is not conducive to students to stay in this unnatural light environment for a long time eye health. [0003] In 2002, Berson et al. from Brown University in the United States discovered the third type of photoreceptor cells in the mammalian retina—retinal specialized photoreceptor ganglion cells (ipRGC). When light enters the human e...
