Problems solved by technology

Therefore, it is considered that the light can be reduced, but in this case, not only the direct light that is likely to become glare light is reduced, but also the reflected light is also reduced, so the utilization efficiency of the emitted light of the LED may be reduced.

Embodiment Construction

[0060] Hereinafter, a preferred embodiment is exemplified, and with reference to the drawings, a two-wheeled motor vehicle headlight device (hereinafter, also simply referred to as a headlight device) according to the present invention will be described in detail.

[0061] First, refer to figure 1 , To illustrate the overall structure of the motorcycle 10. It should be noted that as long as there is no special mention, follow figure 1 The arrow directions shown illustrate the front and rear and up and down directions, and the left and right directions are described based on the direction viewed from the driver seated on the vehicle body. In addition, in figure 1 In the case of a component composed of a pair of left and right, only the left side is marked with a symbol.

[0062] figure 1 It is a left side view of the motorcycle 10. The motorcycle 10 has a frame 28, which is mainly composed of a head tube 12, a main frame 14, a pivot plate 16, a seat frame 18, a sub-frame 20, a down...

Abstract

The present invention provides a low-cost motorcycle headlight device capable of improving the utilization efficiency of light emitted by LEDs with a simple structure while effectively preventing oncoming vehicles or pedestrians from being dazzled. The headlamp device (46) of the motorcycle (10) is equipped with an LED (108) as a light source, a reflector (ii0) that reflects the emitted light of the LED (108), and makes the reflection of the reflector (ii0) A lens (114) through which light passes. A light shielding part (112) is integrally provided on the lens (114), and the light shielding part (112) extends toward the LED (108) side to reduce or block light from the LED (108) (especially the low beam LED (106)) At least a portion of the outgoing light is directed towards the lens (114).

Description

Technical field [0001] The present invention relates to a headlight device of a motorcycle using LED as a light source. Background technique [0002] In the headlight devices of motorcycles, LED (Light Emitting Diode) is recently used as the light source. For example, in the headlamp device described in Patent Document 1, a projection lens is provided in front of the LED, and a part of the light emitted by the LED is directly incident on the projection lens. In addition, the remaining part of the emitted light is reflected by a mirror provided around the LED and enters the projection lens as reflected light. Hereinafter, when the light that directly enters the projection lens is referred to as "direct light", and the light that is incident as reflected light is referred to as "indirect light", finally all direct light and indirect light enter the projection lens. The projection lens diffuses and is then irradiated as irradiated light for irradiating the road surface. [0003] 【P...
