摘要： The present subject matter is directed to a system and method for producing a batwing light distribution. A lens is illuminated with a light source, preferably an LED, and the lens is configured to internally reflect a portion of the illuminating light back in a direction generally opposite to the initial illumination direction. Another portion of the light from the light source may pass through other lens surfaces but may also be reflected back past the light source with a reflector positioned on the other side of the lens from the light source. The light source may be mounted on a frame so as to obscure light therefrom from view.

摘要： Embodiments of a lens element have a body that incorporates geometry that defines features for surfaces that receive and transmit light, e.g., from a light emitting diode (LED) device. These features include, for example, curves, bends, arcs, and like curvilinear objects and/or shapes. These embodiments employs these features to change the direction of light that transits the body. These changes can reflect, refract, and/or re-direct light, thus rendering light that emits from the lens element with one or more light distributing characteristics. In one embodiment, the body comprises a cavity with an inner surface that has a first section and a second section that curve, respectively, with positive concavity and with negative concavity relative to the LED device.

摘要： A solid state lamp for retrofit of an HID includes a circumferential array of solid state light sources mounted on circuit boards, a heat sink located in the lamp's interior volume, and a fan positioned in the interior volume to force airflow across the heat sink. A capper assembly includes at least one aperture to vent the interior volume, and an intermediate circuit board within the capper assembly. The intermediate circuit board distributes electrical power to the circuit boards by tabs and contacts extending from the boards that are mechanically bonded together. An optical transmissive shield is positioned exterior to the circumferential array, and can include prismatic structures to direct light emitted from the LED sources in an off axis direction.

摘要： Embodiments of a lamp that utilizes a reflector and a light source with light-emitting diode (LED) devices to generate an optical intensity distribution substantially similar to that of a conventional incandescent light bulb. These embodiments utilize an operation configuration with parameters that define relationships between components of the lamp to generate the optical intensity distribution. These parameters can, in one example, set out the position of the reflector relative to the light source as well as the ratio between dimensions of the reflector and the light source. In one embodiment, the reflector is in position relative to the light source to form a blocking area proximate the light source that defines a part of the lamp that does not diffuse light.
