AI Technical Summary

Technical Problem

In existing vehicle lighting fixtures, the substrates of the first and second light-emitting elements are located at the front and rear, resulting in a complex structure that makes it difficult to form light distribution patterns with different brightness using a simple structure.

Method used

The system employs multiple projection lens sections arranged side-by-side in the vehicle width direction. Multiple light-emitting elements are mounted on a common substrate in pairs behind each projection lens section, and high-brightness and low-brightness light-emitting elements are arranged alternately. Direct light is irradiated towards the front of the lamp through the light-transmitting component.

Benefits of technology

It enables the formation of multiple light distribution patterns with different brightness under a simple lamp structure, suppresses local heat load, avoids damage to optical functions, and improves the appearance design and the miniaturization and lightweight of the lamp.

Abstract

本发明提供车辆用灯具。构成为通过将来自多个发光元件的直射光经由透光部件朝向灯具前方照射而形成灯具配光图案，能够以简单的灯具构造形成亮度不同的多个配光图案。作为透光部件（20），在构成为具备在车宽方向上并排配置的三个投影透镜部（22A、22B、22C）的基础上，构成为六个发光元件（30A、30B、30C、40A、40B、40C）在三个投影透镜部（22A~22C）各自的灯具后方侧，以在车宽方向上每两个并排的状态搭载于共同的基板（50）。此时，构成为以高亮度发光的发光元件（30A~30C）和以低亮度发光的发光元件（40A~40C）在车宽方向上交替地配置。由此，尽管它们搭载于共同的基板（50），也有效地抑制在车辆用灯具（10）产生局部的热负荷。
