Detailed Description
In order that the present invention may be more clearly understood, the following detailed description is given with reference to the accompanying drawings.
Example 1:
referring to fig. 1 to 9, the present embodiment provides a thick-wall light guide structure, including: the light guide body 1 is made of a colorless transparent material, and the light converging surface 11 is sequentially arranged in the light guide body 1 along a light path and is used for converging light emitted by a light source, the total reflection surface is used for reflecting the light passing through the light converging surface 11 into parallel light, and the light emitting surface 15 is used for projecting the reflected light.
Furthermore, the total reflection surface adopted in the present embodiment includes a first reflection area 12, a second reflection area 13, and a third reflection area 14 sequentially arranged along the optical path; the first reflecting area 12 is used for reflecting the light rays passing through the light ray converging surface 11 into parallel light rays; the light converging surface 11 comprises a spherical surface 11-1, a paraboloid 11-2 and an inclined surface 11-3 which are connected in sequence. The spherical surface 11-1 is a concave spherical structure, and the inclined surface 11-3 is distributed from the paraboloid 11-2 to the side of the second reflection area 13 in an inclined manner.
The second reflective region 13 includes a plurality of pattern units that are sequentially spaced and distributed in rows. The second reflecting region 13 is in an inclined distribution structure relative to the parallel light rays formed by the reflection of the first reflecting region 12; and the end of the second reflective region 13 facing the first reflective region 12 is lower than the end of the second reflective region 13 away from the first reflective region 12. More specifically, a plurality of pattern units are sequentially and obliquely arranged upwards from the reflecting surface to the direction far away from the reflecting surface
In detail with reference to the drawings, each pattern unit includes a first reflection inclined surface 131 and a second reflection inclined surface 133 which are obliquely distributed with respect to a parallel light ray formed by reflection in the first reflection region 12; and a transition surface 132 is formed between the first and second reflective slope surfaces 131 and 133. Here, the transition surface 132 is a substantially flat end surface parallel to the parallel light rays reflected by the reflecting surface. Therefore, only the first reflection slope 131 and the second reflection slope 133 exert a reflection action for light for each pattern unit.
On the basis of the above structure, it should be further noted that, for each pattern unit, the first reflection inclined surface 131 on the pattern unit is located on the side adjacent to the light converging surface 11, and the second reflection inclined surface 133 is located on the side relatively far from the light converging surface 11. Also, an inclination angle of the first reflecting slope 131 with respect to the parallel light reflected by the reflecting surface is smaller than an inclination angle of the second reflecting slope 133 with respect to the parallel light reflected by the reflecting surface. The first reflection inclined plane 131 and the second reflection inclined plane 133 are designed mainly to make full use of pattern units to form reflection and conduction effects on light, and reflection angles formed by the first reflection inclined plane 131 and the second reflection inclined plane 133 are different, so that light emitting angles of light can be further enriched.
In an alternative embodiment, the first reflective region 12 is parabolic and coated with aluminum film to improve the reflection efficiency of the optical structure of the whole surface light source.
In an alternative embodiment, the third reflective region 14 is patterned.
In addition, in order to avoid the problem of bright spots of light finally emitted by the light guide structure of the whole thick-wall part, at least one light-emitting surface 15 is formed with a light-emitting pattern 16. The light is led out through the design of the light-emitting patterns 16, bright spots caused by light reflection are avoided, and the problem of skin pattern weakening bright spots is also solved.
Example 2:
on the basis of the thick-walled light guide structure of embodiment 1, the present embodiment provides a light emitting system comprising: the light guide structure of the thick-walled member of embodiment 1 and the surface light source module 2 disposed below the light guide structure of the thick-walled member; wherein, the surface light source module 2 is provided with a single LED luminous piece. The luminous center of the LED luminous piece is superposed with the spherical center of the spherical surface.
More specifically, the light guide body 1 and the surface light source module 2 are connected in a positioning manner through a plurality of riveting columns. Only one LED emitting element needs to be disposed on the surface light source module 2 of this embodiment. The whole area light source module 2 is approximately in a rectangular flat plate type structure, so that the miniaturization of the area light source optical structure can be realized, and the occupied space of the area light source optical structure applied to the car lamp is reduced.
Since the LED light emitting members of the surface light source module 2 are disposed near one of the width directions corresponding to the rectangular configuration thereof. Therefore, the light converging surface 11 of the corresponding light guiding structure of the thick-walled member is also formed at one end position of the light guiding body 1 towards the surface light source module 2 in the length direction.
In summary, for the case that the light guiding structure of the thick-walled member of the present embodiment is applied to the light emitting system, the light converging surface 11 collects the light output from the light source, a small portion of the light can be directly transmitted to the third reflecting region 14, most of the light is reflected by the first reflecting region 12 into parallel light and then reaches the second reflecting region 13, and the light is transmitted to the third reflecting region 14 after the light is totally reflected by the second reflecting region 13; the light reaching the third reflection region 14 mostly reaches the light exit surface 15 through total reflection, and the whole thick-walled light guide structure is lightened. After the light is reflected for many times in the conduction path, the uniform emergent of the light with the ultra-large luminous width can be realized in a narrow lamp body space, so that the uniform lighting effect is realized.
In the above process, the light passing through the spherical surface 11-1 of the light converging surface 11 travels along a straight line, most of the light passes through the first reflecting area 12 and the second reflecting area 13 to reach the third reflecting area 14, the light is mainly responsible for illuminating the horizontal part of the light emitting area of the light emitting system, and the virtual focuses of the horizontal parts of the second reflecting area 13 and the third reflecting area 14 are coincident; the light passing through the paraboloid 11-2 is refracted, so that the light directly reaches the bent part of the third reflecting area 14, and is responsible for lightening the bent part of the light emitting area of the light emitting system. A small portion of the light passes through the first reflecting area 12 and the paraboloid 11-2 to reach the inclined plane 11-3, and the light reaching the surface is conducted to the corner position of the third reflecting area 14 through the total reflection action. Above, through the effect of light surface 11 that assembles for LED illuminating part emergent ray can cover the light emitting area of whole thick walled casting lighting system, realizes the even effect of lighting up.
