  • Patent number: 10009531
    Abstract: A field of view (FOV) extender may include prisms that direct light from an angle outside of an angle of view associated with a lens of camera, onto the image sensor of the camera, thereby piecewise extending the field of view of the camera beyond the unaltered angle of view of the camera. The prisms may be oriented to direct light around an outer region of the image sensor, which may generate signals use for motion detection purposes. Each prism may be spaced apart from an adjacent prism by a gap, which may create an alternating sequence of prisms and gaps. An inner region of the image sensor may capture imagery that may be suitable for output to a user.

    Abstract: Optical components for lighting devices and lighting devices including such components are described. In some embodiments the optical components are in the form of a lens that alter the distribution of light produced by a lighting fixture. In some embodiments, the lenses are in the form of a downlight to wallwash lens which, when placed in a downlight fixture, convert the light distribution to that of a wallwash fixture, e.g., causing the downlight to produce an off-axis light distribution, without changing the fixture. The lens includes a body with a light source facing side and an opposite room facing side having two optically active regions, each including structures that redirect a portion of light received through the light source facing side and incident thereon. The first region includes structures that redirect, via refraction, and the second region includes structures that redirect, in part via total internal reflection.

    Abstract: A light guide (201) including a transparent element is presented. The transparent element includes a first surface (203) for acting as a light-ingress surface and a second surface (204) for acting as a light-egress surface. The second surface includes elevations (205) for directing a part of the light into directions sideward with respect to a direction in which another and greater part of the light exits the transparent element through the second surface. Each elevation is shaped to provide total internal reflection for a light beam on a first point of the surface of the elevation and refract the reflected light beam on a second point of the surface of the elevation so as to direct the light beam sideward. The sideward directed light enables an observer, who sees the light guide from a small viewing angle, to easily see whether the light is on or off.

The diffusion membrane covers the light output surface and is made of a transparent material and includes a plurality of transparent bumps on the surface. The circuit board is located below the lamp shade. Through the concave shape of the light cups and repetitive reflection of the bumps, light can be condensed to avoid scattering and loss. Moreover, as the light is greatly and uniformly condensed, ghost images can be eliminated.

  • Patent number: 8721115
    Abstract: A light panel is disclosed. The light panel comprises a circuit assembly, a plurality of light sources, a light reflective structure, and a diffuser layer. The light reflective structure has a plurality of concaves, which are continuously connected to form a plurality of ridges. Each of the concaves has an opening formed on the bottom surface thereof, and each of the light sources is disposed corresponding to each of the openings of the concaves. The diffuser layer is supported by the ridges of the light reflective structure. In some aspects of the present invention, the diffuser layer may have a sloping inner surface or is coated with patterned diffuser coatings on the top surface. Each light source can be added with a lens.

  • Patent number: 8582053
    Abstract: A light exit surface of an illuminating lens has a first light exit surface and a second light exit surface. The first light exit surface is recessed toward a point on the optical axis, and the second light exit surface extends outwardly from the periphery of the first light exit surface. The first light exit surface has a transmissive region and a total reflection region. When the position of a light source on the optical axis is defined as a starting point, the transmissive region transmits light that has been emitted from the starting point at a relatively small angle with respect to the optical axis, and the total reflection region totally reflects light that has been emitted from the starting point at a relatively large angle with respect to the optical axis.

    Abstract: The present disclosure relates to a lighting fixture. In one embodiment, the lighting fixture includes a reflector and a lens. The reflector includes a first flange that defines a forward opening and includes at least one tab receiver outside of the forward opening. The lens has an outer periphery and includes at least one tab that is configured to mate with the tab receiver of the first flange, such that when each tab is mated with a corresponding tab receiver, the lens is affixed to the reflector. In this arrangement, there are no dark spots visible on the lens due to the presence of the tabs when light is emanating from the lighting fixture.
