Title:
VEHICLE LIGHT FIXTURE
Document Type and Number:
WIPO Patent Application WO/2024/080178
Kind Code:
A1
Abstract:
Provided is a vehicle light fixture in which brightness variations are reduced on a lamp-light emitting surface of a lamp in which a plurality of light sources are arrayed. The vehicle light fixture is provided with a plurality of LEDs (light sources) (32) that are arrayed in one direction, and a second inner lens (7) having latticed lens steps (71) for refracting and thereby deflecting light emitted from the LEDs (32). The lens steps (71) include main lens steps (dedicated lens steps) (72) that deflect the light from the LEDs (32) in a required direction, and sub-lens steps (common lens steps) (73) that deflect the light from two adjacent LEDs (32) in respectively required directions. In the sub-lens steps (73), the lights of the LEDs (32) are synthesized to reduce brightness variations.
