Title:
LIGHT SOURCE MODULE AND LIGHT FIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/111307
Kind Code:
A1
Abstract:
A light source module comprises a white light generation portion (2) and a red light generation portion (1). The white light generation portion (2) emits first white light, and the red light generation portion (1) emits red light. The maximum spectral intensity value of the light emitted by the red light generation portion (1) is greater than the maximum spectral intensity value of the light emitted by the white light generation portion (2). The light emitted by the red light generation portion (1) and the light emitted by the white light generation portion (2) are mixed to form second white light. The spectral radiant energy of the light emitted by the red light generation portion (1) in the range of 600 nm to 780 nm accounts for 30.0-50.0% of the total radiant energy of the second white light in the visible light region, that is, in the range of 380 nm to 780 nm. The light source module optimizes spectral distribution and increases the energy of a red light region while limiting the specific energy proportion to 50% or less, thereby balancing night staff requirements for working efficiency and rhythmic stimulation. The invention is particularly applicable to people working at night.
