Description

Tail lamp device with uniform side overall light emission

Technical Field

The utility model belongs to the technical field of vehicle lamps and lanterns part, a tail lamp device of the whole luminous homogeneous in side is related to.

Background

In the design of automobile tail lamps at present, L ED automobile lamps have the advantages of energy conservation, environmental protection, low energy consumption, long service life, uniform lighting, small volume and the like, and are increasingly widely adopted in the design of automobile lamps.

However, as the shape, appearance and lighting effect of the lamp are more and more required by customers, and the shape of the future lamp is more and more miniaturized, the space for designing L ayout is more limited, and the light-emitting uniformity becomes a problem which is difficult to solve at present.

1. The light guide light emitting mode has the advantages that the data manufacturing time of the light guide teeth is long in the design stage, and the requirement on forming accuracy is high. The use and popularization are not strong;

2. l ED reflection type light emitting mode, because the coating precision requirement to the reflector is higher, difficult management and control.

In addition, the luminous effect is not good, the area close to the L ED light source is too bright, the area far away is relatively dark, and the use popularization is not strong.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, overcome prior art's shortcoming, provide a tail lamp device of the whole luminous homogeneous in side, adopt luminous PCB board and the transparent light guide plate that has an L ED, light on the light guide plate of lighting realizes through the reflection principle that the lamp shade homogeneity is luminous.

In order to solve the technical problem, the utility model provides a tail lamp device of whole luminous homogeneous in side, including lamp shade (1), interior lamp shade (3), light guide plate (4), support (5), lamp body (6) and PCB board (12) that have 1L ED, support (5) are fixed in lamp body (6) through the screw on, install the border on lamp shade (1), pass through fix with screw interior lamp shade (3) on the border, install light guide plate (4) between interior lamp shade (3) and support (5), install PCB board (12) that have 1L ED in lamp body (6).

The utility model discloses the technical scheme who further injects is: the decorative ring comprises a first decorative ring (2) and a second decorative ring (7), and the first decorative ring (2) and the second decorative ring (7) are spliced with each other.

Furthermore, the inner lampshade (3), the decorative ring and the bracket (5) are fixed with each other through screws.

Furthermore, the surface of the inner lampshade (3) is provided with leather grains.

The utility model has the advantages that:

1. 1L ED light source is used, so that the use number of L ED is reduced, and the cost is reduced;

2. the light guide plate is adopted to transmit the light source, so that the problem of traditional point luminescence is solved, and the technical requirement of surface luminescence is met.

Detailed Description

Example 1

The tail lamp device with the uniform side overall light emission comprises a lampshade 1, an inner lampshade 3, a light guide plate 4, a support 5, a lamp body 6 and a PCB 12 with 1L ED, wherein the support 5 is fixed on the lamp body 6 through a screw, a decorative ring is arranged on the lampshade 1, the inner lampshade 3 is fixed on the decorative ring through a screw 9, the light guide plate 4 is arranged between the inner lampshade 3 and the support 5, and the PCB 12 with 1L ED is arranged in the lamp body 6.

The decorative ring comprises a first decorative ring 2 and a second decorative ring 7, and the first decorative ring 2 and the second decorative ring 7 are spliced.

The inner lampshade 3, the decorative ring and the bracket 5 are fixed with each other through

screws

8, 10 and 11.

The surface of the inner lampshade 3 is provided with dermatoglyph.

Firstly, light emitted by an L ED light source is directly irradiated on a transparent light guide plate 4 to form a uniform luminous body on the light guide plate 4, then a plurality of luminous sources are formed on the luminous body and directly irradiated on an inner lampshade, and dermatoglyphs are arranged on the surface of the inner lampshade 3 and can scatter the received light, so that the light on the surface of the lampshade 1 is more uniform, and the requirement of uniform light emission is met.

The judgment method is that a circle with the diameter of 5mm is drawn on the surface of the lampshade, and the luminance ratio of 2 circles separated from each other is within 1: 1.2.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
