Description

TECHNICAL FIELD

[0001] The present application relates to a kind of automobile signal lamp structure and the automobile using this kind of signal lamp. BACKGROUND

[0002] In the field of automobile signal lamp lighting, the traditional lighting mode is mainly realized by bulb reflection or LED cooperating with transparent thick wall, aluminized reflector and other optical parts. With the vehicle lamp modeling no longer limited to square and single planar layout mode, becoming more three-dimensional, the free curved surface with more complex and changeable modeling trend appears. In the prior art, the most commonly used form for the above-mentioned modeling needs is LED cooperating with light guide, because the light guide can be arranged according to the modeling trend of the light emitting surface, and the structure is relatively simple compared with other ways. However, this form also has various defects and limitations in practical application.

[0003] As shown in the prior art automobile signal lamp structure shown in Figure 1 , the light emitting surface of the light guide is relatively narrow, 1 is a light guide support, 2 is a light guide, 3 is a light distribution mirror, and A is a light emitting range. This structure is usually only applied to occasions with a narrow light emitting surface. For occasions with a wide light emitting surface, there are currently two forms commonly used: one is the form of light guides arranged side by side, i.e. the structure shown in Figure 2 , a plurality of light guides 4 are arranged side by side. The disadvantage of this structure is that a dark area will appear at the joint of the two light guides. The other is that the front of the light guide is matched with a scattering inner fitting. The light can be uniformly distributed through the scattering of the inner fitting. The disadvantage of this form is that the transmittance of the scattering material is relatively low, and the energy output by the light guide is wasted seriously, so a LED with relatively high power is needed to meet the signal lamp regulation requirements, which greatly tests the heat resistance of the lamp and affects the service life of the lamp. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the above-mentioned shortcomings of the prior art, and to provide an automobile signal lamp that can realize uniform lighting effect and meet normal regulation requirements.

[0005] The technical problem to be solved can be solved by the following technical solutions.

[0006] An automobile signal lamp, characterized in that it comprises a first light source and a second light source, the first light source is connected to a first light guide, the first light guide is positioned on a first support body with scattering properties; the inner side of the first light guide is the first support body, and the outer side is an inner light distribution mirror; the second light source is connected to a second light guide, the second light guide is positioned on a second support body, the second light guide is located on the inner side of the first support body, and the inner side of the second light guide is the second support body.

[0007] As a further improvement of the technical solution, the first support body is a translucent piece with a diffusion effect.

[0008] As one of the preferred embodiments of the present application, the first support body is a transparent piece with an optical skin on the surface.

[0009] As one of the preferred embodiments of the present application, the first light guide piece is a light guide tube or a light guide plate; and the second light guide piece is a light guide tube or a light guide plate.

[0010] As a further improvement of the technical solution, the first light guide piece is two or more light guide tubes arranged side by side; and the second light guide piece is two or more light guide tubes arranged side by side.

[0011] As another preferred embodiment of the present application, the first light source is an LED lamp, and the second light source is an LED lamp.

[0012] Another technical problem to be solved by the present application is to provide an automobile using the automobile signal lamp.

[0013] Still another technical problem to be solved by the present application is to provide another automobile signal lamp which can achieve a uniform lighting effect and meet normal regulatory requirements.

[0014] The technical solution is as follows:

[0015] An automobile signal lamp comprises a first light source and a second light source, the first light source is connected to a first light guide piece, the first light guide piece is positioned on a first support body with scattering characteristics, the inner side of the first light guide piece is the first support body, and the outer side is an inner light distribution lens; and the second light source is located on the inner side of the first support body.

[0016] Further, the first light guide piece is a light guide tube or a light guide plate.

[0018] Figure 1 It is a structural schematic diagram of an automobile signal lamp in the prior art;

[0019] Figure 2 It is a structural schematic diagram of another automobile signal lamp in the prior art;

[0020] Figure 3 It is a structural schematic diagram of the automobile signal lamp of the present application; DETAILED DESCRIPTION

[0021] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0022] In view of the illumination defects of the automobile signal lamp in the prior art, the application provides an optical scheme for the current popular modeling trend, which can meet the modeling creativity and avoid the generation of the above defects.

[0023] As shown in the automobile signal lamp structure, the outer side of the vehicle lamp is an inner light distribution mirror 400, the inner side of the inner light distribution mirror is a light guide 110 positioned on a scattering material support 300, and the inner side of the light guide 110 is a light guide 120 positioned on a common support 200. Figure 3 The scattering material support 300 is made of a translucent material, and the commonly used material is PC or PMMA, and the color is milky white or milky red; the material can diffuse light, so that a uniform lighting effect in all directions is obtained. The dotted line in the figure represents the light emitting range of the light guide 120 (light source).

[0024] The implementation principle is as follows:

[0025] The light emitted by the light guide 120 positioned on the common support 200 is irradiated on the scattering material support 300, and the light guide 110 positioned on the scattering material support 300 emits light, and the light generated by the two light sources is irradiated on the inner light distribution mirror at the same time. The light emitted by the light guide 120 and irradiated on the scattering material support 300 can be uniformly distributed on the inner light distribution mirror 400; as described above, since the transmittance of the scattering material support is low, it cannot meet the requirements of the regulations, and the light emitted by the light guide 110 is used to meet the requirements of the regulations.

[0026] The advantages of this light emitting form are as follows:

[0027] 1. The power of the LED used for the light guide 120 is relatively low, and only needs to meet the uniformity lighting effect.

[0028] 2. The power of the LED used for the light guide 110 only needs to meet the normal regulation requirements.

[0029] 3. The light emitted by the light guide 110 and the light guide 120 is fully integrated, and the energy distribution is uniform, and there is no dark area in the appearance lighting.

[0030] The signal lamp structure provided by the application adopts a scattering material as a light guide support. The specific structure adopts a two-layer light emitting surface, and the two-layer light emitting surface is sandwiched with a light emitting form of the scattering material. The scattering material can also be a transparent piece with a surface pattern (a conventional transparent piece of a lamp, preferably transparent PC or PMMA, etc.), that is, a surface treatment that can produce a scattering effect.

[0031] The above-mentioned light guide 110 and 120 are not limited to light guide tubes, but also apply to other light guide components such as light guide plates. The number of light guides is not limited to one, but can be several arranged side by side, and no dark area will appear at the joint of the light guides. In addition, the light emission form behind the scattering material support is not limited to the light guide form, but other optical forms that can make the scattering material support emit light uniformly.
