Abstract

Provided is a vehicle headlight device which can improve overlooking of pedestrians by a drive, even under adverse conditions such as nighttime or rain at night. A vehicle headlight device includes: a pattern photoirradiator (right-side pattern irradiation lamp) which irradiates light on a predetermined irradiation pattern light distribution region of a vehicle in an irradiation pattern in which a bright region and a dark region are alternately repeated; and a cornering light which irradiates a light distribution region under the irradiation pattern light distribution region in a form in which an entire area is a bright region. In this embodiment, the pattern photoirradiator irradiates light synchronously with the cornering light.

First claim

What is claimed is:

1. A vehicle headlight device comprising:
low beam lamp that irradiates light in a predetermined light distribution area of the low beam lamp of a vehicle;
high beam lamp that irradiates light in a predetermined light distribution area of the high beam lamp of the vehicle;
a pattern photoirradiator which irradiates light on a predetermined irradiation pattern light distribution region of the vehicle in an irradiation pattern in which a bright region and a dark region are alternately repeated; and
a cornering light which irradiates a light distribution region under the irradiation pattern light distribution region in a form in which an entire area is a bright region so as to irradiate the road surface of the light distribution region including the side of the vehicle,
wherein the pattern photoirradiator is provided separately from the low beam lamp, high beam lamp and the cornering light
wherein:
the pattern photoirradiator, the low beam lamp, and the high beam lamp are arranged in this order from an outer side toward an inner side in a width direction of the vehicle; and
the cornering light is disposed below the pattern photoirradiator, the low beam lamp, and the high beam lamp.

2. The vehicle headlight device of claim 1 , further comprising a turn signal lamp which is arranged outwardly of and immediately adjacent to the photoirradiator.

3. The vehicle headlight device of claim 2 , wherein the cornering light is substantially aligned vertically with the turn signal lamp.

4. The vehicle headlight device according to claim 1 , wherein the pattern photoirradiator irradiates light synchronously with the cornering light.

5. The vehicle headlight device of claim 1 , wherein the vehicle headlight device is disposed at each of a left side and a right side of the vehicle to thereby provide a pair of the headlight devices each comprising the low beam lamp, the high beam lamp, the pattern photoirradiator, and the cornering light, and each of the headlight devices further comprises a second pattern photoirradiator which irradiates light on a second predetermined irradiation pattern light distribution region of the vehicle in an irradiation pattern in which a bright region and a dark region are alternately repeated, wherein the second predetermined irradiation pattern light distribution region is positioned more outwardly of and separated from the predetermined irradiation pattern light distribution region.
