Embodiment approach 1

[0033] (Description of the structure of Embodiment 1)

[0034] Figure 1~Figure 11 Embodiment 1 of the vehicle headlamp of the present invention is shown. The configuration of the vehicle headlamp in Embodiment 1 will be described below. In the figure, symbols 1L and 1R are vehicle headlamps (for example, headlights, etc.) in this embodiment. Such as figure 1 As shown, the vehicle headlamps 1L, 1R are mounted on both left and right ends of the front of the vehicle C. As shown in FIG. The vehicle headlamp 1L mounted on the left side L of the vehicle C will be described below. In addition, since the structure of the vehicle headlamp 1R mounted on the right side R of the vehicle C is opposite to that of the vehicle headlight 1L mounted on the left side L of the vehicle C, description thereof will be omitted.

[0035] The vehicle headlamp 1L includes a lamp housing 2 , a lamp glass 3 , a first lamp unit 4 , a second lamp unit 5 , a third lamp unit 6 , and a fourth lamp unit 7...

Embodiment approach 2

[0078] (Description of Embodiment 2)

[0079] Figure 12 Embodiment 2 of the vehicle headlamp according to the present invention is shown. The vehicle headlamp in the second embodiment will be described below. In the picture with Figure 1~Figure 11 The same symbols represent the same components.

[0080] In the vehicle headlamps 1L, 1R according to Embodiment 1 described above, the first lamp unit 4 is arranged inside the vehicle C relative to the second lamp unit 5 (in front of the vehicle mounted on the left side L of the vehicle C). In the case of the headlamp 1L, it is the right side R, and in the case of the vehicle headlamp 1R mounted on the right side R of the vehicle C, it is the left side L). In the vehicle headlamp in Embodiment 2, the first lamp unit 4 is disposed on the lower side D of the vehicle C with respect to the second lamp unit 50 .

[0081] The second lamp unit 50 of the vehicle headlamp in Embodiment 2 is the second lamp unit 5 of the vehicle headla...

Abstract

The present invention provides a vehicle headlamp. The object of the present invention is that conventionally, only a light distribution pattern for DTL obtained by diffusing a light distribution pattern for driving can be obtained. Means for solving the above-mentioned problems is that the present invention includes a first lamp unit (4) and a second lamp unit (5). The first lamp unit (4) includes a semiconductor-type light source (14), a reflector (15), a shade (16), and a drive mechanism (17). The reflector (15) has a first reflective surface (21) and a second reflective surface (22). The first reflective surface (21) illuminates the side light distribution patterns (CPL, CPR). The second reflective surface (22) illuminates the light distribution pattern (HP) for high beam. As a result, in the present invention, in addition to the side light distribution pattern (CPL, CPR), any auxiliary light distribution pattern such as a point light distribution pattern or a diffusion light distribution pattern can be obtained.

Description

technical field [0001] The present invention relates to a vehicle headlamp comprising: a first lamp unit for switching and emitting an auxiliary light distribution pattern and a high beam (driving) light distribution pattern; ) light distribution pattern of the second lamp unit. Background technique [0002] Such a vehicle headlamp is conventionally known (for example, Patent Document 1). Hereinafter, a conventional vehicle headlamp will be described. A conventional vehicle headlamp includes: a light source unit that switches and irradiates a DTL light distribution pattern and a running light distribution pattern by switching a diffusion lens; and a light source unit that irradiates a passing light distribution pattern. In conventional vehicle headlamps, by switching the diffusion lens, the light from the light-emitting element of the light source is irradiated as a light distribution pattern for driving without passing through the diffusion lens, and the light from the li...
