LIGHT-EMITTING DEVICE AND SENSOR UNIT
Document Type and Number:
WIPO Patent Application WO/2021/182231
Kind Code:
A1
Abstract:
A first light source (141) emits first light (L1) including a first wavelength that is a visible wavelength. A second light source (142) emits second light (L2) including a second wavelength that is different from the first wavelength. A first substrate (161) supports the first light source (141) and has an opening (161a) that permits passage of the second light (L2). A rotating reflector (15) reflects the first light (L1) and the second light (L2) while rotating or turning so that a first scanning region (SR1) is irradiated while the first light (L1) is scanned in a prescribed direction, and so that the second light (L2) that has passed through the opening (161a) is oriented toward a second scanning region (SR2) while being scanned in the prescribed direction.
