Embodiment approach

[0064] In addition, by arranging the second light emitting surfaces 18b of the organic EL elements 10 so that they face each other, in a laminated body composed of two organic EL elements 10, the first light emitting surfaces 18a of the two organic EL elements 10 face the laminated body. outside of the body. As a result, the luminance of the vehicle lamp 1 can be maintained regardless of which of the organic EL elements 10 is turned on to emit light. Even in a structure in which two of the organic EL elements 10 are overlapped to face the same direction, the vehicle can be maintained by increasing the current supplied to the organic EL element 10 having the first light-emitting surface 18a facing the inside of the laminated body. Use the brightness of fixture 1. However, in this case, the lifetime of the organic EL element 10 whose supply current is increased will eventually be shortened. On the other hand, with the present exemplary embodiment, shortening of the lifetime of...

Abstract

A vehicular lamp includes a plurality of organic electroluminescence elements 10; and a flexible printed circuit board 30 to which the plurality of organic electroluminescence elements 10 are connected, the flexible printed circuit board having lines through which each of the organic electroluminescence elements 10 is supplied with electric power independently.

Description

technical field [0001] The present invention relates to a vehicular lamp, and more particularly, to a vehicular lamp used in a vehicle such as an automobile. Background technique [0002] Japanese Patent Application Publication No. 2015-65150 (JP 2015-65150 A) describes a vehicle lamp using an organic electroluminescence element (organic EL element) as a light source. [0003] The inventor considered installing a plurality of organic EL elements in the above-mentioned lamp for a vehicle and lighting each of them independently. In this case, since the number of power supply wirings increases, it is recognized that this leads to an increase in the size of the vehicle lamp. Contents of the invention [0004] The present invention provides a technique for suppressing upsizing of a vehicle lamp including a plurality of organic electroluminescence elements. [0005] One aspect of the present invention relates to a lamp for a vehicle. The vehicle lamp includes: a plurality of ...
