Abstract

A front luminous lamp without dazzling light comprises a shell, a bulb, a lamp cover and a car light glass. The inner wall of the shell is lined with a reflecting mirror. The utility model is specialized in that the shell is integratedly made by an outer paraboloid shell and an inner paraboloid shell. The focus of the outer paraboloid shell keeps a near distance with the top point of the shell. The focus of the inner paraboloid shell keeps a far distance with the top point of the shell. The bulb is arranged between the focus of the outer paraboloid shell and the focus of the inner paraboloid shell. For employing the structure, the polarizing machine in the prior technology can be omitted, and the structure is simplified and the cost reduced. Therefore, the utility model not only has a simple structure, but also a low cost.

Description

Do not have and dazzle the light headlamp

Technical field

The utility model relates to the device that automobile is used, especially a kind of car headlamp.

Background technology

Present prior art, the Chinese patent ZL patent No.: 93227159.6, invention and created name: do not have the light of change auto lamp, constitute by bulb, the light source polarizer, lampshade and lamp lens.When having overcome driver's meeting, the troublesome poeration that brings owing to conversion light.Existing problems are: complex structure, cost height.

Summary of the invention

The purpose of this utility model is: provide a kind of nothing to dazzle the light headlamp, it is not only simple in structure, and cost is low.

The utility model is achieved in that a kind of nothing dazzles the light headlamp and comprise housing, bulb, lampshade and lamp lens, inner walls is lined with reflective mirror, its special character is: described housing is integrated into by the parabolic housing in the outside, inboard parabolic housing, the summit of the focal length housing of the parabolic housing in the described outside is near, and the summit of the focal length housing of the parabolic housing in described inboard is far away; Described bulb is between the focus of the focus of the parabolic housing in the outside and inboard parabolic housing.

The utility model does not have the light of dazzling headlamp, and described housing is integrated into by the parabolic housing in the outside, inboard parabolic housing, and the summit of the focal length housing of the parabolic housing in the described outside is near, and the summit of the focal length housing of the parabolic housing in described inboard is far away; Described bulb is between the focus of the focus of the parabolic housing in the outside and inboard parabolic housing.Owing to adopt such structure, save polarizer of the prior art, simplified structure has reduced cost.So it is not only simple in structure for the utility model, and cost is low.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, be x axle positive direction with garage's direction, level (road inboard) left is a y axle positive direction, sets up rectangular coordinate system in space.Outside parabola A focal point F ₁Near from parabolical summit o.Inboard its focal point F of parabola B ₂The summit o of shrinking away from theshell body is far away.Outward, inboard parabola A, B focal axis overlap, and is combined together to form asymmetric parabola.Look down along x axle positive direction, plane, parabola place becomes face angle at 45 during beginning with level, light source C just in time with two focal point F ₁, F ₂Overlap two-end-point F ₁, F ₂The light that sends is respectively through medial and lateral parabola B, A reflection becoming directional light.

As shown in Figure 2, a kind of nothing is dazzled the light headlamp and is comprised housing (not identifying among the figure), bulb 3, lampshade (not shown) and lamp lens (not shown), inner walls is lined with reflective mirror, described housing is integrated into by the parabolic housing 1 in the outside, inboard parabolic housing 2, the focal point F 1 of the parabolic housing 1 in the described outside is near apart from the summit of housing, and the focal point F 2 of the parabolic housing 2 in described inboard is far away apart from the summit of housing; Described bulb 3 is between the focal point F 2 of the focal point F 1 of the parabolic housing 1 in the outside and inboard parabolic housing 2.

Claims

1, a kind of nothing is dazzled the light headlamp and is comprised housing, bulb, lampshade and lamp lens, inner walls is lined with reflective mirror, it is characterized in that: described housing is integrated into by the parabolic housing in the outside, inboard parabolic housing, the summit of the focal length housing of the parabolic housing in the described outside is near, and the summit of the focal length housing of the parabolic housing in described inboard is far away; Described bulb is between the focus of the focus of the parabolic housing in the outside and inboard parabolic housing.
