Title:
LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216118
Kind Code:
A1
Abstract:
This lighting device (60) comprises: a first reflective member (120) which has a first reflectance for primary light having a first wavelength and a second reflectance for secondary light having a second wavelength that is other than the first wavelength, with the second reflectance being higher than the first reflectance; and a light conversion member (130) on which the primary light is incident after passing through the first reflective member (120), and which converts at least some of the primary light into the secondary light. This lighting device (60) comprises a holding unit (140) which holds the first reflective member (120) and the light conversion member (130) so that: the light conversion member (130) is at a distance from the first reflective member (120); and the primary light that has passed through the first reflective member (120) is incident on the light conversion member (130). The holding unit (140) controls the relative distance between the first reflective member (120) and the light conversion member (130) in the central axis direction of the primary light that travels from the first reflective member (120) to the light conversion member (130).
