  • Patent number: 9417423
    Abstract: The fixing structure of the micro projector includes a base, a plurality of abutting members and a plurality of fixing components. The base has an assembling plane. The abutting members are respectively disposed on the assembling plane. Each abutting member has an abutting wall, and each optical lens is abutted against each corresponding abutting wall. The fixing components are respectively disposed on the assembling plane and correspond to the abutting walls respectively, and each fixing component fixes each corresponding optical lens on each corresponding abutting wall. Based on this, there is no need to apply adhesives for fixing the optical lens. Additionally, upon assembling the optical lens, since no adhesives are applied it is not necessary to adjust the angle of the optical lens thereby improving the convenience of assembly and reducing the assembly time.

  • Publication number: 20140192555
    Abstract: A planar light apparatus is disclosed and includes a reflection part, a secondary optic device, and a light-emitting device. The secondary optic device has a light incident surface, a light emitting surface, and a side surface, which is an elliptic surface, between the light incident surface and the light emitting surface. A reflecting surface of the reflection part and the light emitting surface face a void space formed between the secondary optic device and the reflection part. Light beams emitted by the light-emitting device into the secondary optic device through the light incident surface can be reflected by the side surface to emit out of the secondary optic device through the light emitting surface into the void space to be reflected by the reflecting surface. Thereby, the planar light apparatus without a conventional light-guiding plate still can offer a planar light source with certain uniformity and can be structured thinner.
