Title:
LIGHTING APPARATUS OF VEHICLE
Document Type and Number:
Japanese Patent JP2020155384
Kind Code:
A
Abstract:
To provide a lighting apparatus of a vehicle that can be made compact even if a light-emitting surface is increased.SOLUTION: In a lighting apparatus 1 of a vehicle, multiple lighting lights 11 are sequentially juxtaposed in one line to a printed circuit board 12, light guide plates 2A-2E are arranged, respectively, while being layered in response to each lighting light 11, and respective light guide plates 2A-2E with different length are arranged by being sequentially layered so as to be long or short in length. In a back side 2A1 of the shortest light guide plate 2A, a first lighting display unit is formed by giving optical diffusion processing or forming an optical diffusion zone so as to enable optical diffusion. When layered sequentially, the light guide plates 2B-2E other than the shortest light guide plate 2A are sequentially arranged while becoming long by the difference. In back sides 2B1-2E1 of the long difference, a second lighting display unit is formed by giving the optical diffusion processing or forming the optical diffusion zone so as to enable the optical diffusion.SELECTED DRAWING: Figure 2
