Description

Technical Field

[0001] The utility model belongs to the field of vehicle lamps, and particularly relates to a novel light guide strip. Background Art

[0002] Light guide strips are structures used in automotive headlights to guide and emit light. Existing light guide strips have problems such as low thermal conductivity, easy ablation, and single color. As consumers' demands for the quality of automotive headlights become increasingly higher, existing light guide strips can no longer meet the needs of current consumers. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the present invention provides a new type of light guide strip, which can improve the thermal conductivity of the light guide strip and avoid the problem of light guide strip ablation.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a new type of light guide strip, including a light guide strip, which is a transparent body, with a reserved space inside the light guide strip, into which a transparent liquid is injected, and the reserved space is opened along the axis of the light guide strip.

[0005] Furthermore, a rare gas is injected into the reserved space, and a pattern is provided on the outer surface of the light guide strip along its axial direction.

[0006] Furthermore, the transparent liquid or the rare gas in the reserved space has a color.

[0007] Compared with the existing technology, the beneficial effects of the present invention are: the present invention can reduce the solid material of the light guide strip and reduce the material cost; it can reduce the overall gram weight of the light guide strip and play a weight-reducing role; it can reduce the ablation of the light guide strip due to heat generated by the light source and reduce after-sales claims; it can beautify the appearance of the light guide strip and simultaneously beautify the appearance of the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the structure of the utility model Figure 1 ;

[0009] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 ;

[0010] Figure 3 This is a schematic diagram of the structure of the utility model after transparent liquid or rare gas is injected. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0012] See also Figure 1-3 The technical solution provided by the present invention is: a new type of light guide bar, which is installed in the car light. At the same time, the LED particles 4 are located outside the side of the light guide bar 1 and facing the middle of the light guide bar 1. The light source is irradiated on the light guide bar 1. While the light is propagated along the axial direction of the light guide bar 1, the light is also irradiated to the surroundings in the light guide bar 1. The present invention includes a light guide bar 1, which is a transparent body. Since the light guide bar 1 is a transparent body, the light can be emitted to the surroundings. A reserved space 2 is provided inside the light guide bar 1. A transparent liquid is injected into the reserved space 2. The reserved space 2 is opened along the axial direction of the light guide bar 1. The reserved space 2. The size is designed according to customer needs. After the transparent liquid is injected into the reserved space 2, the transparent liquid can accelerate the heat transfer speed of the light guide bar 1, thereby reducing the temperature of the light guide bar 1 and preventing the light guide bar 1 from being ablated. On the other hand, the transparent liquid in the light guide bar 1 has a refractive index. The setting of the transparent liquid can change the direction of the light path. Since the light guide bar 1 is generally L-shaped, the direction of the light path is controlled by setting the transparent liquid. The transparent liquid inside the light guide bar 1 can be customized according to the thermal conductivity requirements, the refractive index of the light path and other requirements. The transparent liquid can be water, antifreeze or oil, etc.

[0013] Specifically, another embodiment of the present invention is that a rare gas is injected into the reserved space 2, and a pattern 3 is provided on the outer surface of the light guide bar 1 along its axial direction. The rare gas has a heat insulating effect and can also reduce the temperature of the light guide bar 1 to prevent the light guide bar 1 from being ablated; the pattern 3 on the outer surface of the light guide bar 1 is to control the direction of the light path, and the pattern 3 can be added according to the requirements of the car light design.

[0014] Specifically, the transparent liquid or rare gas in the reserved space 2 has color, thereby beautifying the appearance of the light guide strip and simultaneously beautifying the appearance of the car.

[0015] The production process of the utility model is as follows: first, a reserved space 2 is set inside the light guide strip 1 during production, then the reserved space 2 is injected into the desired transparent liquid, and finally the injection port is sealed.

[0016] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
