As shown in the drawings, the light guide device according to the embodiment of the present invention has a horn shape as a whole, has an oblong racetrack shape in horizontal cross section, has an incident light region 100 at the bottom, a light guide region 200 at a side wall portion, and a light exit region 300 inside the side wall, and includes a first incident surface 101 at an end of the incident light region 100, the first incident surface 101 receiving and emitting light from a first light source 410 located at the end of the incident light region 100; the light guiding region 200 includes a first reflective surface 201 and at least one other reflective surface, the first reflective surface 201 is located at a position close to the bottom inside the sidewall portion, and includes at least a portion of a tapered surface opposite to the first incident surface 101 and inclined with respect to the first incident surface 101, and reflects the light from the first incident surface 101 to the at least one other reflective surface, the at least one other reflective surface is located at the outer side of the sidewall portion, each of the at least one other reflective surface includes an arc-shaped surface section, and the light from the first reflective surface 201 reaches the light exit region 300 located at the inner side of the sidewall portion after being reflected at least once at the arc-shaped surface section of the at least one other reflective surface; the light exit area 300 exits light rays from the arc-shaped surface segment of the at least one other reflective surface to form at least one arc-shaped lighting area.
In an embodiment of the present invention, the first reflecting surface 201 includes at least a portion of a conical surface, and can reflect light from the first incident surface 101 toward a different radial direction of the hammer surface, similar to the sun radiating light outward. Further, at least one other reflecting surface also has an arc-shaped surface section, which can receive and reflect the light from the first reflecting surface 201, and finally realize an arc-shaped lighting area.
As shown, the first incident surface 101 includes a plane refraction surface, which is a horizontal plane in the figure, and the light from the first light source 410 enters the light guide device only through the refraction of light, so that the light entering the light guide device is not collimated.
Wherein the focal point of the first reflecting surface 201 is positioned near the first light source 410 and is selected such that light rays from the first incident surface 101 are reflected by the first reflecting surface 201 substantially in parallel. Specifically, when determining the focal point of the first reflecting surface 201, the virtual focal point of the light of the first light source 410 refracted by the first incident surface 101 needs to be at the same position as the focal point of the first reflecting surface 201 in consideration of the refraction effect of the first incident surface 101, so that the light can be reflected by the first reflecting surface 201 substantially in parallel.
The above arrangement allows incident light rays to be effectively reflected substantially entirely by the first reflective surface 201 with little or no loss of light. If the first incident surface 101 is replaced with the light incident portion 120 of the collimator type having a substantially M shape as shown in fig. 1, the lighting effect of the arc-shaped lighting area is not uniform due to the loss of light rays by such a collimator (especially, at the reflection surfaces on both sides). In the present embodiment, the first incident surface 101 and the first reflecting surface 201 cooperate to obtain a relatively uniform lighting effect of the arc lighting area.
Wherein the central axis of the conical surface of the first reflecting surface 201 is substantially parallel to the emission axis of the first light source 410.
As shown in the figure, the at least one other reflective surface includes a second reflective surface 202, a third reflective surface 203, and a fourth reflective surface 204, wherein the second reflective surface 202, the third reflective surface 203, and the fourth reflective surface 204 are respectively located at different heights of the periphery of the sidewall, the arc surface section of the second reflective surface 202 reflects the light from the first reflective surface 201 to the arc surface section of the third reflective surface 203 and the arc surface section of the fourth reflective surface 204, respectively, and the arc surface section of the third reflective surface 203 and the arc surface section of the fourth reflective surface 204 reflect the light from the arc surface section of the second reflective surface 202 to the light emitting area 300, respectively, so as to form arc lighting areas. Such an arrangement makes it possible to form lighting areas of two arc patterns, which may be parallel to each other according to the position between the second and third reflection surfaces 202 and 203.
It is also conceivable by the person skilled in the art to provide more reflecting surfaces 204' similar to the third and fourth reflecting surfaces 203, 204 at different heights on the periphery of the side walls, so that more than two side-by-side arc-shaped patterns can be formed.
As shown, the arcuate surface segments of the second reflective surface 202 comprise at least a portion of a conical surface, typically but not limited to a semi-conical surface, such that a semi-circular arc segment can be formed, the arcuate surface segments of the third and fourth reflective surfaces 203 and 204 comprise at least a portion of a cylindrical surface, such that there is a transition region between the second, third and fourth reflective surfaces 202, 203 and 204, the central axes of the conical and cylindrical surfaces are substantially parallel, and the arcuate surface segments of the third and fourth reflective surfaces 203 and 204 are staggered in a direction transverse to the central axis of the cylindrical surface. The arrangement is such that the arcs of the plurality of light exit patterns are formed with a controllable separation distance therebetween.
As shown, the surface of the light emitting area 300 includes at least a portion of the tapered surface adjacent to the first reflective surface 201 and opposite to the at least one other reflective surface. Therefore, the whole light guide device has a hollow structure while ensuring the required light emitting effect, and the material and the cost are saved.
As shown, the light emitted from the light emitting area 300 also forms at least one linear lighting area connected to the at least one arc lighting area. The arc lighting area and the linear lighting area can be smoothly connected, and the visual effect with aesthetic feeling is realized.
The light incident region 100 includes a first light incident portion 110 and at least one second light incident portion 120, wherein the first light incident portion 110 receives light from the first light source 410 and includes the first incident surface 101, and the at least one second light incident portion 120 receives and emits light from at least one second light source 420; the light guiding region 200 further includes a fifth reflecting surface 205 connected to the first reflecting surface 201, each of the at least one other reflecting surface further includes a linearly extending section connected to an arc-shaped section, the fifth reflecting surface 205 reflects at least the light from the at least one second light incoming portion 120 to the linearly extending section of the at least one other reflecting surface, and the light from the fifth reflecting surface 205 reaches the light exiting region 300 after being reflected at least once at the linearly extending section of the at least one other reflecting surface; the light exit area 300 exits light rays from the linearly extending section of the at least one other reflective surface to form at least one linearly lit area. Wherein the fifth reflecting surface 205 is a plane reflecting surface, and the number of the fifth reflecting surfaces 205 is two, and V-shaped grooves are formed to be inclined to each other. The above arrangement enables a set of light exit patterns to be formed that resemble a racetrack with curved transitions, where the individual racetracks are parallel with a certain spacing between them.
As shown, the first light incident portion 110 is further configured to guide a portion of the light from the first light source 410 to the fifth reflective surface 205. Such an arrangement enables the transition between circular arc rectilinear patterns to be achieved using only one light source. The number of light sources is saved and the structure is simplified while the continuity and the brightness of the pattern are ensured.
As shown, the first light incident portion 110 further includes a part of a collimator to collimate a part of the light from the first light source 410 to the fifth reflective surface 205, and the second light incident portion 120 includes a collimator to collimate at least a part of the light from the second light source 420 to the fifth reflective surface 205. The collimator may be any one of collimators in the related art, for example, a collimator having a substantially M-shape. As described above, although such a collimator has light loss at the reflecting surfaces on both sides, for the linear lighting area, since a plurality of such collimators are arranged side by side, the light rays from the collimators are crossed, so that the linear lighting area also has a relatively uniform lighting effect.
As shown in the figure, the scattering element 210 in a zigzag shape is disposed on the reflection surface of the at least one other reflection surface that directly reflects the light to the light exit area 300. Such an arrangement causes the light reflected by the first reflective surface 201 to be scattered by the scattering element 210 when it travels to the at least one other reflective surface before being reflected again, making the light more uniform.
As shown, the linearly extending sections of the fifth reflective surface 205 and the at least one other reflective surface each comprise a planar reflective surface. This makes it possible to form the light exit pattern of the linearly extending section at both ends of the arc light exit pattern.
In the above embodiment, the light exit area 300 is located inside the sidewall portion of the light guide, according to another embodiment of the present invention, the light exit area 300 may be located on the top surface of the light guide, in which case, the at least one other reflective surface may include the second reflective surface 202, and the arc-shaped surface section of the second reflective surface 202 reflects the light from the first reflective surface 201 directly to the light exit area 300 to form the arc lighting area.
The lighting areas realized by the light guide device are not limited to the above-mentioned racetrack pattern, and according to practical needs, it is also conceivable by those skilled in the art that the light guide device may include a combination of a plurality of first reflective surfaces 201 and at least one other reflective surface, thereby realizing a plurality of arc-shaped lighting areas, which may be connected to each other, for example, forming a flower-shaped lighting area.
According to practical requirements, one skilled in the art can also imagine that the number of the fifth reflective surfaces 205 of the light guiding area 200 is only one, so that a lighting area of a hook pattern can be formed.
Another aspect of the present invention provides a vehicle lamp assembly, which includes the above light guide device; and at least one light source for emitting light toward the light guide device.
Another aspect of the present invention provides a vehicle, including the above-mentioned lamp assembly.
