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 those in the vehicle described below. That is, the up-down direction coincides with the vertical direction, and the left-right direction coincides with the vehicle width direction. In addition, in the drawings used in the following description, an arrow UP indicates an upward direction, an arrow FR indicates a front, and an arrow LH indicates a leftward direction.

[0035] First, a schematic configuration of an entire saddled vehicle equipped with a lighting device for a vehicle according to an embodiment will be described.

[0036] figure 1 It is a right side view which shows the motorcycle of embodiment.

[0037] Such as figure 1 As shown, in this embodiment, a scooter-type motorcycle 1 will be described as an example of a straddle-type vehicle. The...

Abstract

The invention provides a lighting device for a vehicle. The cost increasing is inhibited. The design and visual effect of the appearance of the lighting device are both improved. A headlight includesan LED light source, a substrate on which the LED light source is mounted, and a reflecting member configured to reflect light radiated from the LED light source. The reflecting member includes a reflector that is provided in a radiation direction of the LED light source with respect to the LED light source and that has a first reflecting surface configured to reflect light radiated from the LED light source toward outside, a second reflecting surface that is provided in the radiation direction of the LED light source with respect to the LED light source and that is configured to reflect lightradiated from the LED light source, the second reflecting surface being separately provided from the first reflecting surface, and a third reflecting surface that faces a side opposite to the LED light source and that is configured to reflect the light reflected by the second reflecting surface toward outside.

Description

technical field [0001] The present invention relates to a vehicle lighting device. Background technique [0002] Conventionally, there is a lighting device for a vehicle using an LED (Light Emitting Diode) as a light source (see, for example, Japanese Patent Laid-Open No. 2017-204343). In Japanese Patent Application Laid-Open No. 2017-204343, a headlight device for a vehicle is disclosed, which includes a light source and a reflector portion, the reflector portion has a reflective surface that reflects light emitted from the light source toward the front, and the light source is An LED that emits light in a predetermined direction. [0003] However, LEDs cannot irradiate light to at least the rear side of a mounting substrate, and thus irradiate light with higher directivity than conventional halogen lamps and the like used as light sources of vehicle lighting devices. Therefore, when an LED is used as a light source of a lighting device for a vehicle, the portion where li...
