The positioning of the light guiding body 1 is applied to the vehicle lamp in this embodiment, but it is only for illustration and is not limited thereto; the embodiment includes a lamp holder 2 which is formed with a chamber 21 And forming an opening 22 at one end, and forming a plurality of connecting holes 23 at the other end, the light guiding body 1 is disposed in the chamber 21, the light emitting surface 121 is located at the opening 22, and the set of holes The light source 3 is disposed at the light-incident surface 111, and the light holder 2 is further provided with a transparent cover 24 at the opening 22 to protect the light-guiding body 1.

For the incident light entering the light incident surface 111, the light source 3 disposed at the light incident surface 111 is used to provide light incident. For example, the light source 3 can be an LED (Light-emitting diode) light emitting module. In the embodiment, the light source 3 has a wide illumination angle, and is effective for improving the light. Therefore, in an embodiment, the light guide body 1 is inserted into the light guide body 1 . At the light surface 111, a light collecting unit 113 is further disposed, so that the light of the light source 3 is converged and refracted into parallel light to be parallel to the optical axis L of the light incident surface 111 to refract light to be perpendicular to the light incident surface 111. In a preferred embodiment, the light collecting unit 113 is integrally formed with the light guiding body 1 to achieve modularization and reduce the cost of assembly and manufacturing.

The wall surface of the groove 114, that is, the first reflecting surface 112 may be a reflecting surface or a total reflecting surface.

In a preferred embodiment, the first reflective surface 112 is a total reflection surface, so that the refractive index of the material of the light guiding body 1 and the incident position of the light incident surface 111 can be matched. And the groove 114 is cut to form a first reflecting surface 112 of the total reflection surface; and the light that the first reflecting surface 112 can enter the light incident surface 111 is evenly distributed and reflected to the light entering portion. 11 periphery, so preferably, the wall surface of the groove 114 corresponds to the optical axis L and is slightly conical, it is known that the tip of the groove 114 will correspond to the center of the light-incident surface 111; In order to improve the uniformity and saturation of the light, it is preferable that the angle of the groove 114 is such that the first reflecting surface 112 reflects the light incident on the light incident surface 111 to the light entering portion. And the second reflective surface 13 and the light exiting portion 12 are at least partially disposed on the periphery of the light incident portion 11, so that the groove 114 is not necessarily a full cone shape, preferably It may be a conical shape having a chamfered angle corresponding to the second reflecting surface 13 and the light exiting portion 12.

Therefore, as shown in FIGS. 4 and 5, the light of the light source 3 is reflected by the light collecting unit 113, and then reflected by the first reflecting surface 112 to the second reflecting surface 13, since the first reflecting surface 112 is as described above. The conical arrangement is such that, regardless of the A-A cross-sectional direction as shown in FIG. 4 or the B-B cross-sectional direction shown in FIG. 5, the first reflective surface 112 can accurately reflect the light to The second reflective surface 13.

In an embodiment, the light-emitting surface 121 is a surface of the flower-biting surface, which is merely an example and is not limited thereto.

The light-emitting portion 12 is generally made of a transparent material. In order to prevent the reflective tooth surface 131 from being directly viewed from the outer side of the light-emitting surface 121, in an embodiment, the light-emitting portion 12 is coupled to the light-incident portion 11 The arrangement is slightly vertical, so that the light-emitting surface 121 can shield the reflective tooth surface 131, and at the same time, the optical light distribution design of the reflective tooth surface 131 can be favored.

The light-emitting portion 12 is disposed on the periphery of the light-receiving portion 11, and the light-emitting portion 12 is disposed perpendicularly to the light-incident portion 11, so that an arrangement between the light-emitting portion 12 and the light-incident portion 11 is formed. The space 14 is configured to prevent external light from being disturbed by the accommodating space 14 and to prevent the groove 114 and the reflective flank 131 from being viewed by the accommodating space 14. Therefore, in a preferred embodiment, the system further includes a light shielding. The light-shielding plate 4 is shielded from one end of the light-incident portion 11 with respect to the light-incident surface 111, and a side wall of the light-emitting portion 12 at one end of the light-incident surface 111. Thereby, the user can still see the light-emitting surface 121. The light of the light is emitted, and at the same time, other light-emitting units can be disposed at the accommodating space 14 according to the use requirements.
