Title:
LIGHT-EMITTING DEVICE AND SENSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/145695
Kind Code:
A1
Abstract:
In the present invention, a light-emitting device (2) that emits output light (L) comprises a light-emitting element (20) that emits a primary light (L1) and a wavelength converter that converts at least a portion of the primary light (L1) to a secondary light (L2). The output light (L) includes at least a portion of the secondary light (L2). The intensity of the output light (L) is at least a prescribed value across an overall wavelength range of 750 to 900 nm, inclusive. The ratio of the intensity of the output light (L) at 900 nm in relation to the intensity of the output light (L) at 750 nm is at least 0.2 but less than 3.0. The spectral visibility of the output light (L) is 0.1 to 10 lm/W, inclusive.
