As shown in fig. 1 and 2, the light guide assembly includes a light guide bar 10 made of a light transmissive material and at least one light emitter 20, where the light guide bar 10 includes a light guide body 11 and a light guide boss 12 formed by partially protruding from a surface of the light guide body 11. The light emitting body 20 irradiates light toward the light guide boss 12, the light is transmitted from the light guide boss 12 to the light guide body 11, and then is transmitted along a total reflection light path 21 and a refraction light path 22 formed between two opposite side walls of the light guide body 11, and is transmitted out of the light guide body 11 through the refraction light path 22.

The light guide strip 10 can be made of resin, glass and other light-transmitting materials, and light can be transmitted outwards through the light guide strip 10, so that the light guide strip 10 forms a light effect with a bright effect. The light guide boss 12 is partially protruded from the surface of the light guide main body 11, and the overall light transmission effect is stable. Optionally, the length of the light guide body 11 is much larger than the dimension of the light guide boss 12 in the length direction of the light guide body 11, so that the light output by the light emitter 20 can be transmitted from the light guide boss 12 to the light guide body 11 and propagate along the light guide body 11.

The light emitting body 20 is disposed on the side wall of the light guide boss 12, and the light output direction thereof faces the light guide boss 12 and forms a corresponding angle with the surface of the light guide boss 12. For example, the inclination angle of the central line of the luminous body 20 with respect to the light incident vertical surface of the light guide boss 12 is less than or equal to 30 degrees. Optionally, the central line of the light emitter 20 is perpendicular to the surface of the light guide boss 12, so that the light can be completely injected into the light guide boss 12. The light rays are refracted after entering the light guide boss 12 so that the light rays can enter the light guide body 11 along the light guide boss 12.

The light guide body 11 is formed in a flat elongated structure, light travels along the inside of the light guide body 11, and a part of the light is refracted and reflected when being irradiated to the inner surface of the light guide body 11 to form a refracted light path 22. Wherein part of the light rays forms total reflection at the inner surface of the light guiding body 11 to constitute a total reflection light path 21. In the total reflection optical path 21, light can propagate along the light guide body 11 without losing light energy. The tail end of the total reflection light path 21 and the inner surface of the light guide body 11 form refraction and reflection, so that the light rays of the corresponding total reflection light path 21 can be emitted out of the light guide body 11 at the tail end of the total reflection light path 21, accordingly, correspondingly bright light effect is formed, the light ray propagation distance is long, and the output light effect is good. The light guiding body 11 adjusts the surface structure to make the ends of the different total reflection light paths 21 spaced apart so that the overall brightness of the light guiding body 11 is substantially the same. Light rays are output at the light guide bosses 12 by one or more than one luminous bodies 20, so that luminous effects with basically the same brightness can be formed on the whole light guide main body 11, and the luminous effect is good and the energy-saving effect is good. It should be noted that the total reflection optical path 21 is a propagation path formed by the total reflection of the light on the inner surface of the light guiding body 11, that is, different light can generate its own total reflection optical path 21 when the angle is smaller than or equal to the critical angle, so that the light of different total reflection optical paths 21 can be refracted out of the light guiding strip 10 at different end positions to form the bright light effect.

As shown in fig. 2 and 3, in an embodiment, two light emitters 20 are provided, and the two light emitters 20 are oppositely disposed on two sides of the light guide boss 12. The light emitting bodies 20 are oppositely disposed at two sides of the light guide boss 12, so that light can be incident into the light guide strip 10 in a crossed manner, and extend to the light guide main bodies 11 at two sides of the light guide boss 12, thereby forming a crossed light emitting effect and expanding the light guide range of the light guide strip 10. In addition, the two light emitters 20 are distributed to output light rays to the light guide bar 10 in different directions, the length range of the light guide bar 10 can be correspondingly enlarged, and the light effect output effect is good. For example, the light guiding length of the two light emitters 20 in the light guiding bar 10 can be greater than 50mm, which greatly improves the light guiding range and saves the energy required by the light emitters 20. It should be noted that the light emitting body 20 can be a point light source or a linear light source; alternatively, the light emitting body 20 is formed by combining a plurality of point light sources.

The light guide boss 12 is formed by partially protruding from the surface of the light guide bar 10 to form a light incident portion, which can guide the light output by the light emitting body 20 to be transmitted along the total reflection light path 21 and the refraction light path 22 of the light guide body 11, so that the light guide body 11 has good overall brightness uniformity. Part of the light emitted by the light emitting body 20 is transmitted along the total reflection light path 21, can be transmitted to a far place along the light guiding body 11, and is transmitted out of the light guiding body 11 along the refraction light path 22. The luminous bodies 20 are small in number and can uniformly diffuse light to the whole light guide body 11, the light guide body 11 is wide in light guide range, and the whole light effect is good.

As shown in fig. 2 and 4, in an alternative embodiment, the light guide body 11 includes a top plane 112 and a bottom plane 111 disposed opposite to each other, wherein the bottom plane 111 is partially protruded to form the light guide boss 12. The bottom plane 111 is provided with a dimming texture 13, and the dimming texture 13 is located on the propagation path of the total reflection light path 21 to adjust the reflection direction of the light.

The top plane 112 is a surface layer of the light guide strip 10, the refracted light path 22 irradiates the top plane 112, and the light can be transmitted out of the top plane 112 to form different light effects. The light of the total reflection optical path 21 forms total reflection at the top plane 112 and the bottom plane 111, and accordingly, the light of the total reflection optical path 21 can propagate in the length direction along the light guide body 11. The bottom plane 111 is provided with a dimming texture 13, and the dimming texture 13 divides the bottom plane 111. The light is totally reflected in the area where the dimming texture 13 is not arranged, and is reflected when irradiating the dimming texture 13 and changes the angle of irradiating the top plane 112, so that the light can be transmitted out of the top plane 112, and a corresponding light effect is formed. When the total reflection light path 21 irradiates the dimming texture 13, correspondingly, the dimming texture 13 is the end of the total reflection light path 21, the reflection direction of the light is changed, and part of the light is transmitted outwards from the top plane 112, so that a corresponding light effect is formed. That is, the light on the different total reflection light paths 21 changes the reflection direction at the dimming lines 13, so that the overall lighting effect of the light guide main body 11 is balanced, and the lighting effect stability is good.

In one embodiment, the dimming lines 13 are uniformly distributed on the bottom plane 111. Dimming lines 13 evenly distributed in bottom plane 111 can make the light that luminous body 20 sent evenly distributed in the length direction of light guide body 11, improves the equilibrium of the whole light efficiency of light guide body 11. Of course, different light effects can be realized by adjusting the distribution position of the dimming lines 13. In an optional embodiment, the density of the dimming texture 13 gradually increases from the light guide boss 12 to the end of the light guide body 11, so as to achieve a gradually changing light effect.

The light guide boss 12 is convexly disposed on the bottom plane 111, and an end surface of the light guide boss 12 is substantially parallel to the bottom plane 111. In an optional embodiment, the end surface of the light guide boss 12 is provided with the dimming texture 13, so that the light emitted by the light emitting body 20 forms a refraction light path 22 at the end surface of the light guide boss 12, and the overall illumination balance of the light guide strip 10 is improved.

As shown in fig. 5 and 6, the light adjusting lines 13 are used to adjust the reflection direction of the light, so as to change the reflection angle of the light of the total reflection optical path 21, and transmit the light out of the top plane 112, and the light emitting range has good controllability. In an embodiment, the light-adjusting texture 13 is configured as a convex arc-shaped bump or a convex arc-shaped rib protruding from the bottom plane 111. Optionally, the dimming lines 13 are formed by a plurality of arc bosses distributed at intervals on the bottom plane 111, wherein the arc bosses are distributed at intersection points of the grid to form an evenly distributed state. The light of the total reflection light path 21 is irradiated to the arc-shaped salient point, the reflecting surface of the arc-shaped salient point is an arc-shaped surface, and the angle of the light reflected by the arc-shaped surface is larger than the critical angle, so that the light is emitted from the top plane 112 to form a bright part. Optionally, the dimming texture 13 is formed by a plurality of arc-shaped ribs distributed at intervals on the bottom plane 111, and the arc-shaped ribs are parallel to the light guide boss 12. Similarly, the light of the total reflection light path 21 is irradiated to the arc-shaped convex rib, the reflection surface of the arc-shaped convex rib is an arc-shaped surface, and the angle of the light reflected by the arc-shaped surface is larger than the critical angle, so that the light is emitted from the top plane 112 to form a bright part.

In another embodiment, the light modulation texture 13 is a concave-arc-shaped pit or a curved groove formed by sinking from the bottom plane 111. In this embodiment, the principle of changing the light propagation by the arc pits or the arc grooves is basically the same as that by the arc bumps or the arc ribs, and the description thereof is omitted.

As shown in fig. 7, in an embodiment, the light guide strip 10 further includes a light reflecting layer 30 attached to the bottom plane 111. The reflective layer 30 is attached to the bottom plane 111 to improve the reflectivity of the light on the bottom plane 111, so that the light can be emitted out of the light guide strip 10 from the top plane 112, and the overall brightness of the light guide strip 10 is improved. Alternatively, the light-reflecting layer 30 is provided as a light-reflecting coating applied to the bottom plane 111. The light-reflecting layer 30 is provided as a silver coating applied to the bottom plane 111, for example. Alternatively, the light-reflective layer 30 is provided as a light-reflective film attached to the bottom plane 111. In an optional embodiment, the dimming texture 13 is disposed on the reflective layer 30 to simplify the processing of the light guide strip 10.

In one embodiment, a diffusion film 40 is further attached to the surface of the light guiding body 11, and the diffusion film 40 is disposed on the surface of the top plane 112. The diffusion film 40 has the function of diffusing light, that is, the light is scattered on the surface of the diffusion film 40, and the light is diffused softly and uniformly.
