  • Publication number: 20240060615
    Abstract: A reflecting device includes at least one reflecting cavity corresponding to at least one light source. A first reflecting cavity located at an extremity of the reflecting device includes a first reflecting part, able to receive incident light from the light source corresponding to the first reflecting cavity, and reflect this light towards the second reflecting part. A second reflecting part adjoins the first reflecting part is able to reflect the reflected light from the first reflecting part towards the outside of the first reflecting cavity. The first reflecting cavity at the extremity of the reflecting device may include a first reflecting part and a second reflecting part, which are able to subject light rays from the light source to double reflection. This can considerably increase the design flexibility of the first reflecting cavity.

  • Patent number: 11761600
    Abstract: A light-guiding component includes a light introduction section, the light introduction section including a first light incidence portion and a second light incidence portion that face different directions. The first light incidence portion is capable of receiving incident light from a light source that corresponds to the first light incidence portion, and the second light incidence portion is capable of receiving incident light from a light source that corresponds to the second light incidence portion. A light-guiding section provided with a light exit surface and configured to guide the light from the first light incidence portion or the second light incidence portion to be propagated therein and then exit from the light exit surface.

  • Publication number: 20230167959
    Abstract: The present utility model provides an optical element, comprising: a light entry surface; a first reflective surface and a second reflective surface; a light exit surface; and at least one connecting surface, located between the first reflective surface and/or the second reflective surface on the one hand and the light exit surface on the other, wherein the connecting surface at least partly comprises an enhanced reflection part for expanding a maximum exit angle of emergent light exiting via the light exit surface. Advantages: there is no need to process a surface at the light exit surface, so the range of applicability of the optical element is increased; moreover, the optical element according to the present utility model has a greater distance between the light exit surface and light entry surface thereof, i.e. can be thicker, so the optical element can adapt to a greater variety of shapes.

  • Patent number: 10677410
    Abstract: A light beam adjusting device performs a process on at least two kinds of light beams in combination. Through this light beam adjusting device, a part of a first light beam is emitted from a first light exit face and another part thereof may be emitted from a second light exit face. Similarly, a part of the second light beam is also emitted from the first light exit face, and another part thereof may be emitted from the second light exit face. In this way, regardless of whether the first light beam is turned on or the second light beam is turned on, the light adjusted by the light beam adjusting device can be simultaneously emitted from the first light exit face and the second light exit face.
