The car lamp comprises a thick wall and an inner lens which are fixed together front and back, most of direct light emitted from a light source enters the thick wall, is reflected by a reflecting surface and then is emitted out of the thick wall, and a first key lighting effect is realized; the oblique light rays emitted by the light source enter the inner lens on the back surface of the thick wall and are refracted out through the patterns on the surface of the inner lens, so that the second lightening effect is realized, and the oblique light rays and the light rays are blocked by the shielding decorative ring. These two kinds of illuminating effects superpose together for this car light is rich in space third dimension and science and technology sense more, and the degree of discernment is higher.

Description

Car lamp for realizing double lighting effects of thick wall and inner lens surface patterns by single light source

Technical Field

The utility model relates to an automotive lighting technical field, concretely relates to utilize single light source to realize thick wall and the double car light of lightening effect of inner lens surface decorative pattern.

Background

The thick wall and the inner lens are widely applied to the automobile lamp, and both can realize the refraction and the conduction of light rays. The transmission path of the light in the thick wall is generally as described in CN20517425U, CN208832369U, CN209026739U, CN208886660U, etc., and the light emitted from the light source is reflected by the reflecting surface of the thick wall, passes through the thick wall, and is emitted from the light-emitting surface or the side surface at one end of the thick wall.

The rear lights of automobiles commonly available on the market generally have a thick-walled structure. In addition, better lighting effect of the automobile tail lamp can be realized by the in-plane lens and the decorative patterns integrated on the surface of the in-plane lens. Two kinds of structures of the thick wall of present automobile tail lamp and inner lens are often mutually independent for the lighting effect is comparatively single, lacks discernment degree and design and feels. In addition, the two structures generally need to be matched with independent light sources in the implementation process, and the cost is relatively high and certain difficulty is caused when the two structures are simply combined.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an utilize single light source to realize the double effect of lighting of thick wall and inner lens surface decorative pattern. The vehicle lamp comprises a thick wall, a bracket, an inner lens and a PCB; the thick wall and the inner lens are fixedly connected with the bracket, and an assembly body formed by the thick wall and the inner lens is fixedly connected with the PCB; a light source is arranged at the position of the surface of the PCB, which is opposite to the end part of the thick wall and the end part of the inner lens; part of light emitted by the light source enters the thick wall through the light guide column, is reflected by the reflecting surface and then is emitted from the other end part or the outer surface of the thick wall, so that a first key lighting effect is realized; and another part of light emitted by the light source enters the inner lens and is refracted by the patterns arranged on the surface of the inner lens to form a second lightening effect.

Furthermore, a shielding decorative ring is fixedly connected to the part outside the light-emitting surface of the inner lens, and is used for preventing other light emitted by the light source from being scattered out to influence the lighting effect.

Furthermore, the patterns on the surface of the inner lens are in a long and thin strip shape, and a plurality of groups (more than 2 groups) are arranged at certain intervals.

Furthermore, 3-5 groups of light sources are arranged on the surface of the PCB at certain intervals, and the light sources are specifically LEDs.

Furthermore, the connection mode between the thick wall and the inner lens and the bracket and between the PCB board and the assembly body is selected from at least one of clamping, screw connection and bonding.

Furthermore, the shapes of the thick wall and the inner lens are both slender strips with certain radian.

Further, the car light is specifically a steering light.

Compare with the mode of lighting of current single thick wall or interior lens structure car light, the utility model discloses with the help of single light source through the reflex reflector of two kinds of forms and two kinds of corresponding light transmission paths, realized thick wall and the dual effect of lighting of interior lens surface decorative pattern simultaneously. This car light simple structure, occupation space are few, manufacturing cost is lower, and it is more rich in space third dimension, science and technology sense, design sense to light the back, and the degree of discernment is also higher, has produced better economic value.

Detailed Description

In order to make those skilled in the art fully understand the technical solution and advantages of the present invention, the following embodiments are further described.

A tail lamp turn signal as shown in fig. 1-5 has an elongated shape with a certain curvature. The tail lamp steering lamp mainly comprises a steering lamp thick wall, a support, a steering lamp inner lens (double colors) and a PCB, wherein the steering lamp thick wall is a traditional side light-entering type thick wall, and the steering lamp inner lens is a bottom light-entering type. The thick wall of the steering lamp and the inner lens of the steering lamp are respectively fixed on two sides of the bracket, the PCB is fixed on an assembly body formed by the thick wall of the steering lamp and the inner lens of the steering lamp, and finally the PCB is integrally installed on a vehicle body and is connected with a vehicle circuit. And an LED light source is arranged on the outer surface of the PCB, and the position of the light source is just opposite to the light guide column at the thick-wall end part of the steering lamp and the light inlet end part of the inner lens of the steering lamp.

When the turn light is turned on, the LED light source is lightened and flickers, most of direct light rays emitted by the LED light source are reflected by the reflecting surface to change the direction after passing through the light guide column on the thick wall of the turn light, and finally are emitted from the light outlet at the end part of the thick wall of the turn light (figure 4), so that the first key lighting effect is realized. Meanwhile, part of oblique rays emitted by the LED light source enter from the end part of the inner lens of the steering lamp close to the light source and are refracted by a plurality of groups of elongated stripe patterns on the surface of the inner lens of the steering lamp and then emitted out, so that the secondary lighting effect is realized. In the process, other light rays emitted by the light source are blocked by the shielding decorative ring arranged outside the light-emitting surface of the lens in the turn light, and are not scattered out to influence the lighting effect; the non-optical pattern area on the inner lens of the steering lamp and the thick wall of the steering lamp generates mirror reflection, so that no light is emitted. In a comprehensive way, the different lighting modes of the same light source realize the double lighting effect, and the light emitted by the light source is utilized to the maximum extent, so that the tail lamp steering lamp visually presents a spatial stereoscopic impression, and the identification degree is higher.

At present, the automobile lamp is developed and tested, namely, a large amount of new automobile models come into the market along with a certain host factory. Compare in the interior lens fairing plane + of tradition realization similar effect spray paint radium carving or the scheme of moulding plastics of double-colored, the utility model discloses the scheme is simpler, the cost is also lower.
