Abstract

The invention relates to a multi-section color temperature adjustable white LED lamp structure based on a full spectrum. The white LED lamp structure comprises a glass substrate, a supporting substrate and a control module; a plurality of blue light chips are fixedly arranged on the supporting substrate; a plurality of fluorescent body areas which are in one-to-one correspondence with the blue light chips are arranged on the glass substrate; the blue light chips are used for exciting full-spectrum fluorescent bodies in the fluorescent body areas; and the control module is electrically connected with the plurality of blue light chips to control the turn-on or turn-off of the blue light chips. The technical problem that an existing artificial light source disturbs human circadian rhythm is solved.

Description

technical field [0001] The invention relates to a white LED lamp, in particular to a structure of a white LED lamp with adjustable multi-segment color temperature based on full spectrum. Background technique [0002] With the rapid development of the information age, people spend more than 12 hours indoors every day and rarely come into contact with sunlight. Generally, when indoors, artificial light sources are mostly used. This kind of artificial light source disturbs the circadian rhythm of human beings, and people have sleep problems and other diseases. Therefore, human beings put forward higher requirements for lighting. [0003] At present, LED white light is mostly used indoors. The existing LED white light is obtained by exciting yellow phosphor powder with blue LEDs. Although the photoelectric conversion efficiency far exceeds that of fluorescent lamps and incandescent lamps, the light quality is not enough, mainly manifested in low display index. Therefore, it is ...
