LED light source and lamp with sunlight visible light part spectrum structure

Abstract

The invention discloses an LED device and light source with a sunlight visible light part spectrum structure. The LED device comprises a blue LED chip or blue fluorescent powder, thereby mixing cyan,red, green and orange spectrum components into an emission spectrum of the LED device by using cyan fluorescent powder, green fluorescent powder, orange fluorescent powder and red fluorescent powder to obtain white light. Compared with the prior art, the LED light source has sunlight emission spectrum configuration, does not contain an ultraviolet or infrared spectrum component and is a healthy light source; the white LED device is packaged by adopting a four-primary color or five-primary color technical scheme, and different from a traditional three-primary color concept and a two-primary color technical scheme adopted for early LED packaging, the four-primary color or five-primary color technical scheme has the advantages that the condition that the most important cyan spectrum componentwith a wavelength range of 480-520nm in a solar spectrum needs to be added is emphasized; the environment-friendly, green and energy-saving requirements are met; and the human health requirements arealso met.

Description

technical field

[0001] The invention belongs to the field of electronic information, specifically semiconductor optoelectronic devices, green lighting and information display, and particularly relates to a packaging method for a white LED device with a configuration for emitting sunlight in the visible light range and a healthy light source made using the device. Background technique

[0002] White light LED is known as the fourth generation of green semiconductor lighting source after incandescent lamps, fluorescent lamps and high-pressure gas discharge lamps. It is friendly to the environment (no mercury pollution), and has the advantages of small size and shock resistance. Therefore, once the LED came out, it has been popularized and applied rapidly, and the penetration rate in the field of display backlight has reached 100%. Although semiconductor lighting has the obvious advantages of energy saving and environmental protection, how to endow LED green lighting with heal...
