The optical element is formed by a light inlet face, a light outlet face opposite to the light inlet face, and a plurality of grating structures of micro meter (?m) scale disposed on the light outlet face. The grating structure includes a first slant face, a second slant face, and a plane surface between the first slant face and the second slant face. In application, a direct downward light emitted by a light source is reflected by the first slant face and the second slant face, to form a circulating light in the grating structure, and that is combined with the direct downward light to output from the light outlet face in achieving reduced glare and increased lumen in application.

  • Patent number: 9869441
    Abstract: This invention provides an optical system that collects 100% of the light emitted from the light source and effectively directs it into the desired beam pattern. This is achieved by a combination of different optical control methods including reflector and lens optics. The cost is controlled by a design that reduces the optical part count to 2 main components, which reduces manufacturing and assembling time and maintains proper alignment to the light source and system.

  • Patent number: 9863605
    Abstract: A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light emitting diodes) are disclosed. In general, the devices include a scattering element in combination with an extractor element. The scattering element, which may include elastic and/or inelastic scattering centers, is spaced apart from the light source element. Opposite sides of the scattering element have asymmetric optical interfaces, there being a larger refractive index mismatch at the interface facing the light emitting element than the interface between the scattering element and the extractor element. Such a structure favors forward scattering of light from the scattering element. In other words, the system favors scattering out of the scattering element into the extractor element over backscattering light towards the light source element.

  • Patent number: 9851063
    Abstract: Disclosed is a vehicle lamp including a projection lens, and a light source located behind the projection lens so that light emitted from the light source is irradiated forward through the projection lens. The projection lens includes an upright wall surface formed on a peripheral edge thereof, in which the upright wall surface has a greater longitudinal inclination angle than a front surface of the projection lens. A light control member is located behind the projection lens, in which the light control member is configured to suppress light incident on the projection lens from the light source, from being internally reflected by the upright wall surface.

  • Patent number: 9822943
    Abstract: A light deflecting device selectively reflects an incident light to a projection optical system. An irradiation optical system irradiates light to a reflective part of the light deflecting device. The light deflecting device has at least some region in the reflective part, a position of which is switchable between a first reflection position where the light irradiated by the irradiation optical system is reflected toward the projection optical system so as to be effectively used as a portion of a desired light distribution pattern, and a second reflection position where the light irradiated by the irradiation optical system is reflected so as not to be effectively used. The irradiation optical system is disposed at a position shifted to a side which a front face of the reflective part in the first reflection position faces, with reference to a vertical plane including an optical axis of the projection optical system.
