Title:
LED LIGHT SOURCE FOR PROVIDING NEAR-NATURAL LIGHT AND LIGHT FIXTURE
Document Type and Number:
WIPO Patent Application WO/2020/000518
Kind Code:
A1
Abstract:
An LED light source for providing near-natural light comprises a base layer (10), at least one set of light-emitting assemblies (20) provided at the base layer (10), and a circuit (30) connected to the light-emitting assemblies (20). The light-emitting assembly (20) comprises a white light emitter (21) and a red light emitter (22). The white light emitter (21) comprises a first chip and an optical conversion film. The red light emitter (22) comprises a red light chip. Red light is used to compensate for a missing red light component in white light with respect to a natural spectrum so as to form near-natural light. Red light in the near-natural light has a relative spectral power greater than 0.60. Green light has a relative spectral power greater than 0.30. Blue light has a relative spectral power less than 0.75. The light source of the present invention can emit near-natural light, reduce blue light, increase green light and red light, protect vision, reduce sub-health issues, and increase a color rendering index. The increase in red light also increases the level of healthy lighting. The light source has a simple configuration and high reliability and adaptability, and is well suited for debugging and application.
