Title:
LIGHTING DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/156668
Kind Code:
A1
Abstract:
Both a planar light-emitting body (6) which emits first illumination light and a semiconductor light-emitting element (7) which emits light toward the planar light-emitting body (6) are arranged in a light chamber (5) which is defined by both a lamp housing (2) which has an opening and a cover (3) which covers the opening. The planar light-emitting body (6) is provided with: a transmission layer which allows light to pass therethrough; and a control layer which controls the direction of propagation of light having been emitted from the semiconductor light-emitting element (7) and having passed through the transmission layer, thereby radiating the light as second illumination light.
