Description
Technical Field
The invention relates to an automobile signal lamp structure and an automobile adopting the signal lamp.
Background
In the field of automobile signal lamp illumination, the traditional illumination mode is mainly realized by bulb reflection or matching of an LED with optical parts such as a transparent thick wall, an aluminum-plated reflecting mirror and the like. As the car lamp shape is not limited to the square and single planar layout mode any more, the car lamp shape becomes more three-dimensional, and a free-form surface with more complex and variable shape trend appears. In the prior art, the most applicable modeling needs are LED and light guide, because the light guide can be arranged according to the modeling trend of the light-emitting surface, and the structure is simpler than other methods. However, there are various drawbacks and limitations to the practical use of this form.
As shown in fig. 1, the light-emitting surface of the light guide is narrow, in the figure, 1 is a light guide bracket, 2 is a light guide, 3 is a lens, and a is a light-emitting range. When the light emitting surface is applied to a wide light emitting surface, two types are commonly used at present: one is in the form of a side-by-side mosaic of light guides, i.e. a structure as shown in fig. 2, where a plurality of light guides 4 are arranged side-by-side mosaic, which has the disadvantage that dark areas may occur at the mosaic of two light guides. The other is that the front of the light guide is matched with the scattering internal configuration, and the light can be uniformly distributed through the scattering of the internal configuration; the disadvantage of this form is that because the scattering material has a low transmittance and the energy output by the light guide is wasted seriously, the LEDs with relatively high power are required to meet the signal light legislation requirements, and at the same time, the heat resistance of the lamp is greatly tested, which affects the service life of the lamp.

The technical problem to be solved by the invention is to overcome the defects in the prior art, and provide an automobile signal lamp which can realize a uniform lighting effect and can meet the requirements of normal regulations.
The technical problem to be solved can be implemented by the following technical scheme.
An automobile signal lamp is characterized by comprising a first light source and a second light source, wherein the first light source is connected with a first light guide piece which is positioned on a first support body with scattering property; the inner side of the first light guide part is the first bracket body, and the outer side of the first light guide part is an inner lens; the second light source is connected with a second light guide part, the second light guide part is positioned on a second support body, the second light guide part is positioned on the inner side of the first support body, and the inner side of the second light guide part is the second support body.
As a further improvement of the present technical solution, the first bracket body is a translucent member having a diffusion effect.
As one of the preferred embodiments of the present invention, the first bracket body is a transparent member with an optical dermatoglyph processed on the surface.

In another preferred embodiment of the present invention, the first light source is an LED lamp, and the second light source is an LED lamp.
Another technical problem to be solved by the present invention is to provide an automobile using the above automobile signal lamp.
Another object of the present invention is to provide an automotive signal lamp which can achieve a uniform lighting effect and meet the requirements of normal regulations.
The technical scheme is as follows:
an automobile signal lamp comprises a first light source and a second light source, wherein the first light source is connected with a first light guide member, and the first light guide member is positioned on a first support body with scattering property; the inner side of the first light guide part is the first bracket body, and the outer side of the first light guide part is an inner lens; the second light source is located on the inner side of the first bracket body.
Further, the first light guide is a light guide pipe or a light guide plate.

FIG. 2 is a schematic representation of another automotive signal construction of the prior art;
FIG. 3 is a schematic view of an automotive signal according to the present invention;
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Aiming at the lighting defects of the automobile signal lamp in the prior art, the invention provides an optical scheme aiming at the current popular modeling trend, which can meet the modeling originality and avoid the defects.
As shown in fig. 3, in the signal lamp structure of the vehicle, an inner lens 400 is provided on the outer side of the lamp, a light guide 110 positioned on a scattering material holder 300 is provided on the inner side of the inner lens, and a light guide 120 positioned on a general holder 200 is provided on the inner side of the inner lens. Wherein, the scattering material bracket 300 is made of semitransparent material, the common material is PC or PMMA, and the color is milk white or milk red; the material can diffuse light, so that a uniform lighting effect is obtained. The dotted line in the figure indicates the light emission range of the light guide 120 (light source).
The realization principle is as follows:
the light emitted from the light guide 120 positioned on the general holder 200 is irradiated on the scattering material holder 300, while the light guide 110 positioned on the scattering material holder 300 emits light, and the lights generated from the two light sources are simultaneously irradiated on the inner fitting. The light emitted from the light guide 120 to the scattering material support 300 can be uniformly distributed on the inner lens 400; as described above, since the transmittance of the scattering material support is low, and the light guide 110 cannot meet the regulatory requirements, the light is emitted from the light guide specifically for the regulatory requirements.
The advantages of this form of illumination are:
1. the LED used for the light guide 120 has low power and only needs to satisfy the effect of uniform lighting.
2. The LED power for the light guide 110 need only meet normal regulatory requirements.
3. The light emitted from the light guide 110 and the light emitted from the light guide 120 are sufficiently merged, the energy distribution is uniform, and no appearance lighting dark area occurs.
The signal lamp structure provided by the invention adopts scattering materials as the light guide support. The specific structure adopts a light-emitting form of two light-emitting surfaces, and scattering materials are entrained between the two light-emitting surfaces. The scattering material may be a transparent material (a conventional transparent material for a lamp, preferably transparent PC or PMMA) with a surface textured, that is, a surface treatment capable of generating a scattering effect may be performed.
The light guide 110 and the light guide 120 are not limited to the light guide, and are also applicable to other light guide members such as a light guide plate. And can not be limited to one in quantity, also can several side by side, dark space can not appear in light guide concatenation department. In addition, the light emitting form behind the scattering material support is not limited to the light guide form, and other optical forms can be used to make the scattering material support emit light uniformly.
