Title:
LIGHT SOURCE MODULE AND LIGHTING FIXTURE
Document Type and Number:
WIPO Patent Application WO/2024/024619
Kind Code:
A1
Abstract:
This light source module emits output light and comprises a first light-emitting unit (10) that emits first light, and a second light-emitting unit (20) that emits white second light. The first light-emitting unit (10) has a first light-emitting element (11). The second light-emitting unit (20) has a second light-emitting element (21), and a phosphor (22) that emits light by being excited by light from the second light-emitting element (21). The output light includes the first light and the second light. The wavelength of the light emission peak of the first light-emitting element (11) is shorter than the wavelength of the light emission peak of the second light-emitting element (21), and is 350-410 nm. The excitation spectrum of the phosphor (22) has a minimum value in a wavelength range in which the first light-emitting element (11) has a light emission intensity at 350-410 nm.
