Problems solved by technology

As a result, the vehicle lighting device as a whole has a dark impression, and there is room for improvement in terms of design and external visibility.
In addition, if a light source is added to improve visibility, component costs increase

Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described based on the drawings. It should be noted that directions such as front, rear, up, down, left, and right in the following description are the same as the directions in the vehicle described below. That is, the up-down direction matches the vertical direction, and the left-right direction matches the vehicle width direction. In addition, in the drawings used for the following description, the arrow UP represents the upper side, the arrow FR represents the front side, and the arrow LH represents the left side.

[0035] First, the schematic structure of the whole saddle-riding type vehicle on which the vehicle lighting device of the embodiment is mounted will be described.

[0036] figure 1 It is a right side view showing the motorcycle according to the embodiment.

[0037] like figure 1 As shown, in the present embodiment, a scooter-type motorcycle 1 will be described as an example of a saddle-riding ...

Abstract

The present invention provides a lighting device for a vehicle in which designability and external visibility are improved while suppressing an increase in component costs. The headlamp includes an LED light source, a substrate on which the LED light source is mounted, and a reflection member that reflects light irradiated from the LED light source. The reflective member includes: a reflective mirror having a first reflective surface that is disposed in an irradiation direction of the LED light source relative to the LED light source and that reflects light irradiated from the LED light source to the outside; a second reflective surface that It is arranged on the irradiation direction of the LED light source relative to the LED light source, and is provided separately from the first reflective surface, and reflects the light irradiated from the LED light source; and a third reflective surface, which faces the side opposite to the LED light source, and The light reflected by the second reflective surface is reflected to the outside.

Description

technical field [0001] The present invention relates to a vehicle lighting device. Background technique [0002] Conventionally, there is a vehicle lighting device using an LED (Light Emitting Diode) as a light source (for example, refer to Japanese Patent Application Laid-Open No. 2017-204343). Japanese Patent Laid-Open No. 2017-204343 discloses a headlight device for a vehicle, which includes a light source and a reflector portion, the reflector portion having a reflecting surface that reflects light emitted from the light source toward the front, and the light source is LEDs that emit light in a predetermined direction. [0003] However, since LEDs cannot irradiate light to at least the back side of the mounting board, they irradiate light with higher directivity than halogen lamps and the like conventionally used as light sources for vehicle lighting devices. Therefore, when an LED is used for the light source of the vehicle lighting device, the portion irradiated with...
