Title:
LED LIGHT-EMITTING UNIT
Document Type and Number:
WIPO Patent Application WO/2016/078012
Kind Code:
A1
Abstract:
An LED light-emitting unit comprising a base (1) provided with an accommodating cavity (11), a first LED chip (2), a fluorescent adhesive layer (3), a transparent substrate (4), and a second LED chip (5). An opening (111) is provided at a side of the accommodating cavity (11). The first LED chip (2) is provided with a first wavelength and arranged at the bottom of the accommodating cavity (11). The fluorescent adhesive layer (3) covers the top of the first LED chip (2) and interacts with the first LED chip (2) to produce a white light. The transparent substrate (4) is arranged above the first LED chip (2) in the accommodating cavity (11). The second LED chip (5) is fixed onto the transparent substrate (4) and is provided with a second wavelength for adjusting the color temperature/coloring rendering index. By regulating the current of the second LED chip (5), a light component of the second LED chip (5) can be added to the spectrum of the white light excited jointly by the first LED chip (2) and the fluorescent adhesive layer (3), thus changing the color temperature and color rendering index.
