  • Patent number: 9618744
    Abstract: A partially transmissive reflective film is provided on a second transparent substrate, and a reflector is provided on a first transparent substrate. The partially transmissive reflective film and the reflector are held parallel to each other with a predetermined spacing therebetween. Thereby, light is incident from a protrusion portion on which the reflector of the first transparent substrate is formed, the light is reflected by the partially transmissive reflective film and the reflector, and the incident light is guided by an air layer between the partially transmissive reflective film and the reflector. A refractive index of the air layer is lower than that of the second transparent substrate. A part of the guided light is extracted from the partially transmissive reflective film, and is emitted from the second transparent substrate on a side opposite to a surface on which the partially transmissive reflective film is provided.

  • Patent number: 9612390
    Abstract: Extended area lighting devices, which are useful e.g. as luminaires, include a light guide and diffractive surface features on a major surface of the light guide. The diffractive surface features are tailored to extract guided-mode light from the light guide. The light guides can be combined with other components and features such as light source(s) to inject guided-mode light into the light guide, light source(s) to project light through the light guide as non-guided-mode light, a framework of interconnected support members (attached to multiple such light guides), and/or a patterned low index subsurface layer that selectively blocks some guided mode light from reaching the diffractive surface features, to provide unique and useful lighting devices. Related optical devices, and optical films having diffractive features that can be used to construct such devices and light guides, are also disclosed.

  • Patent number: 9423557
    Abstract: A backlight component includes a back plate, a fastening module, a light source and a light-guiding plate. The fastening module includes a first plate, a second plate and a third plate. The first plate, the second plate and the third plate define a receiving space. The light source is securely assembled at one side of the second plate and facing toward the receiving space. The light-guiding plate is slidably assembled in the receiving space of the fastening module, and sandwiched between the first plate and the third plate. Accordingly, when the thickness of the light-guiding plate is changed, only the second plate of the fastening module need be changed; additionally, the length of the fastening module can be normalized to apply for display devices with different sizes. Consequently, the manufacturing cost of display devices can be reduced, and the fastening module is applicable to different kinds of display devices.

  • Patent number: 9279568
    Abstract: An illumination device comprises a housing (5) with a plurality of compartments (3), each compartment comprising a respective light emission window (15), a light source (11), and a stack of crossed prismatic sheets (10). Light issued by the light source during operation is made to propagate through the prismatic sheets and subsequently through the light emission window. The orientation of the stack of sheets is different for each compartment, thus causing each compartment to issue a different beam of light. The light source of each compartment is separately switchable, thus enabling easy setting of the type of beam issued form the illumination device. Optionally a diffuser (17, 23) is provided at one side or at both sides of the stack of prismatic sheets to enhance the homogeneity of the issued light.
