Description

Automobile signal lamp and automobile

Technical Field

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.

Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

Lighting defect to automobile signal lamp existence among the prior art, the utility model provides an optical scheme to the molding trend that is popular now can satisfy the molding intention, avoids the production of above-mentioned defect.

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 utility model provides a signal lamp structure adopts the scattering nature material 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.
