    摘要： A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises a cavity. At least a portion of the cavity can have an outline that is egg-shaped in cross section. A backside of the cavity (or a backside portion of the optic) can have an irregular shape for receiving the light emitting diode, for example to form a receptacle shaped to fit a circuit

    摘要： A lighting fixture employing a solid-state light source and an ambient light sensor is disclosed. The solid-state light source is placed within a light source housing and configured to emit light through a lens assembly that covers an opening into a mixing chamber provided within the light source housing. In one embodiment, the ambient light sensor is located within mixing chamber with the solid-state light source. In another embodiment, the ambient light sensor is located outside of the mixing chamber. In either embodiment, the ambient light sensor may be recessed within a waveguide, which aides in controlling the sensor distribution beam for the ambient light sensor. The sensor distribution beam essentially defines an area from which light reflected off of a task surface is accurately monitored via the ambient light sensor. The direction of the sensor distribution beam and the light emitted from the ambient light sensor may generally coincide.

    摘要： A lighting device includes a light source, a reflector having an ellipsoidal reflection surface, an aspherical lens, and an exit pupil. The source is arranged at a first focal point of the reflection surface and a part of the emitted light is reflected from the reflection surface in the direction of a second focal point. The pupil is arranged offset with respect to the second focal point. The lens is arranged between the reflection surface and the pupil in a beam path with the reflected light and is shaped such that a first part of the reflected light passes through the lens with an aperture angle altered by not more than 5° in a central region and passes through the pupil and a second part of the reflected light penetrates through the lens in an outer region and is deflected by the lens and is consequently guided through the pupil.

    摘要： The claimed subject matter provides systems and/or methods that facilitate remotely controlling a wireless lighting module. The wireless lighting module can include a power source such as a battery, a solar cell, and the like as well as an array of light emitting diodes (LEDs). The LEDs can be controlled based upon a received input (e.g., communicated by way of a radio frequency signal, an infrared signal, . . . ). For example, the input can be obtained from a remote control, a sensor, a differing wireless lighting module, an radio frequency identification (RFID) tag, and so forth. The input can be utilized to switch one or more LEDs on or off, change the intensity or color of illumination, modulate illumination, alter the direction of illumination, etc.
