AI Technical Summary

Technical Problem

In existing technologies, the mixed light quality of LED lighting equipment is limited, making it difficult to meet diverse lighting needs, especially in providing light sources with high color rendering index and natural spectrum in different scenarios.

Method used

It employs six electrically independent light-emitting units, namely the first blue light, the second blue light, white light, blue-green light, yellow light, and red light-emitting units. By independently controlling the light mixing of these units, a spectral distribution closer to natural light is formed, and a rhythmically adjustable lighting effect is achieved by regulating the blue-green light units.

Benefits of technology

It improves the quality of mixed light, enabling the provision of light sources with high color rendering index and natural spectrum in different scenarios. At the same time, it achieves the inhibition or promotion of melatonin without changing the color temperature, making it suitable for a variety of lighting scenarios.

Abstract

This application provides a light source module, a lighting system, and a luminaire. The light source module includes six electrically independent light-emitting units: a first blue light-emitting unit emits blue light with a peak wavelength of 430-445 nm; a second blue light-emitting unit emits blue light with a peak wavelength of 460-475 nm; a white light-emitting unit emits white light with a relative color temperature of 6500 K and a color rendering index (CRI) greater than 80; a blue-green light-emitting unit emits blue-green light with a peak wavelength of 480-510 nm and a spectral half-width of 25-35 nm; a yellow light-emitting unit emits yellow light with a peak wavelength of 555-580 nm and a spectral half-width of 105-130 nm; and a red light-emitting unit emits red light with a peak wavelength of 620-660 nm and a spectral half-width of 80-100 nm. Each light-emitting unit is independently controlled, and the emitted light is mixed to form the light emitted by the light source module. The light source module emits three different types of blue light, and the mixed light has higher light quality. The rhythm can be adjusted based on the blue-green light-emitting unit.
