The utility model discloses a light guide is a light guide, goes into light through the light guide both ends, can realize that a light guide accomplishes the annular and lights the outward appearance, and lights the homogeneity good, and no bright spot or dark space to can reduce assembly part quantity, reduction in production cost.
Description
Technical Field
The utility model relates to an automotive lighting technology field, in particular to light guide for car signal lamp.
Background
With the progress of LED technology, LED light sources are widely applied in the automobile lamp industry at present, more and richer appearance changes and applications are derived from the luminous models of the automobile lamps due to market competition and the needs of consumer groups, and different design structures are more diversified in the automobile lamp models. Taking a daytime running signal lamp as an example, the light guide is matched with the LED light source, so that the uniform lighting effect with various appearance shapes can be realized.
In the prior art, in order to realize a ring-shaped or round-shaped profile, which requires a light guide to cooperate with the LED, the optical solutions realized include the following two:
(1) the two light guides are matched with the LED to realize the shape of a ring or a circle;
(2) one light guide is fitted with the LED and the ends are interconnected to form a ring or a ring-around shape.
It follows that if a ring-shaped form is to be achieved, two light guides in cooperation with the LEDs can be achieved; this can be achieved using a single light guide with end interconnections, but this can produce bright spots or dark areas with poor illumination.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough among the correlation technique, provide a light guide for car signal lamp, can realize that a light guide accomplishes the annular and lights the outward appearance, and it is good to light the homogeneity, does not have bright spot or dark space of lighting.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: a light guide for an automotive signaling light, comprising:
the light guide comprises an end part I and an end part II, and when the light guide is observed from a light-emitting normal visual angle, the end part I and the end part II of the light guide are overlapped front and back, and no part of the end part I and the end part II is connected with each other; the inner side of the light guide is provided with an optical surface structure, and the optical surface structures at the end part I and the end part II are overlapped front and back when observed from a light-emitting normal visual angle of the light guide;
a light source disposed below end I and end II.
Preferably, the light emitted by the light source is transmitted out of the molding normal by refraction and reflection.
Preferably, the light rays emanating from the shaping normal may form a complete ring or a circle around the light emitting area.
Preferably, the optical surface structure is a light guide tooth.
Compared with the prior art, the beneficial effects of the utility model are that: the light guide of the utility model has two ends, the two ends are overlapped front and back when being observed from the light guide light-emitting normal visual angle, and the light is incident from the two ends of the light guide, so that one light guide can finish the annular lightening appearance, the lightening uniformity is good, and no bright spots or dark spaces exist; and the number of assembly parts can be reduced, and the production cost can be reduced.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 2, a light guide for a signal lamp of an automobile comprises a light guide 1 capable of being fixed on a vehicle body, the light guide 1 has two ends, i.e., an end i 2 and an end ii 3, and light sources 4 are arranged below the end i 2 and the end ii 3; when the light guide 1 is observed from a light emitting normal visual angle, the end part I2 and the end part II 3 of the light guide 1 are overlapped front and back, and no part is connected with each other near the end part I2 and the end part II 3; the inner side of the light guide 1 is provided with an optical surface structure 5, and the optical surface structure 5 is a light guide tooth; when the light guide 1 is observed from the light emitting normal visual angle, the optical surface structures 5 near the end I2 and the end II 3 are overlapped front and back; as shown in fig. 3, the light emitted by the light source 4 propagates inside the light guide by reflection and propagates out of the shaping normal by refraction, forming a complete ring or a ring around the light emitting area, without producing bright spots or dark areas.
The above is the preferred embodiment of the present invention, and the technical personnel in the field of the present invention can also change and modify the above embodiment, therefore, the present invention is not limited to the above specific embodiment, and any obvious improvement, replacement or modification made by the technical personnel in the field on the basis of the present invention all belong to the protection scope of the present invention.
