Embodiment Construction
[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0021] Such as Figures 1 to 2 As shown, a light guide for automobile signal lamps includes a light guide 1 that can be fixed on the vehicle body. The light guide 1 has two ends, namely end I2 and end II3, and are arranged below end I2 and end II3. There is a light source 4; when viewed from the light-emitting normal direction of the light guide 1, the end I2 and the end II3 of the light guide 1 overlap front and back, and there is no connection between the end I2 and the end II3; the inner side of the light guide 1 is provided with an o...

The invention relates to the technical field of vehicle lighting, in particular to a light guide for an automobile signal lamp. The light guide comprises a light guide unit and a light source, the light guide unit comprises an end part I and an end part II, the end part I and the end part II of the light guide unit are overlapped front and back when being observed from the normal view angle of light outgoing of the light guide unit, and the end part I and the end part II are not connected with each other; an optical surface structure is arranged on the inner side of the light guide unit, and the optical surface structures at the end part I and the end part II are overlapped front and back when being observed from the normal viewing angle of light outgoing of the light guide unit; and the light source is arranged below the end part I and the end part II. The light guide is one light guide, light enters from the two ends of the light guide, annular lighting appearance can be achieved through one light guide, the lighting uniformity is good, bright spots or dark areas do not exist, the number of assembly parts can be reduced, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a light guide for vehicle signal lamps. Background technique [0002] With the advancement of LED technology, LED light sources are currently widely used in the car lighting industry. Due to market competition and the needs of consumer groups, more and richer appearance changes and applications have evolved in the lighting shape of car lights. The design structure is also more diversified in the shape of the lights. Taking daytime traffic lights as an example, the combination of light guides and LED light sources can achieve uniform lighting effects with various appearances. [0003] In the existing technology, in order to realize the shape of a ring or a circle, it is necessary to cooperate with the light guide and the LED. The optical schemes realized include the following two types: [0004] (1) The two light guides cooperate with the LED to realize the shape of a r...
