    Abstract: Ambient light sensor circuitry includes a photodetector, a controllable current source, and control circuitry. The photodetector is coupled between a supply voltage and an intermediate node and configured to provide a photodetector current proportional to an amount of light detected thereby to the intermediate node. The controllable current source is coupled between the intermediate node and ground and configured to shunt a portion of the photodetector current from the intermediate node to ground based on a current control signal. The control circuitry is coupled to the intermediate node and the controllable current source and configured to provide the current control signal to the controllable current source, receive a measurement signal from the intermediate node, adjust the current control signal such that the measurement signal does not exceed a maximum input threshold of the control circuitry, and provide an ambient light measurement signal based on the current control signal.

    Abstract: Assume that the two groups of lighting fixtures are located in the same general area, employ daylighting, and provide light that can be sensed by each other. A first group will determine an actual lighting contribution provided by the second group and remove the actual lighting contribution provided by the second group when making daylighting decisions. As such, when the dimming level of the second group is changed, the first group will effectively ignore changes in the dimming level of the second group when making daylighting decisions, and vice versa. A group of lighting fixtures may include one or more lighting fixtures.

    Abstract translation: 假设两组照明装置位于相同的一般区域，采用采光，并提供彼此可以感测的光。 第一组将确定第二组提供的实际照明贡献，并在作出采光决定时，删除第二组提供的实际照明贡献。 因此，当第二组的调光水平改变时，第一组将在进行采光决定时有效地忽略第二组的调光水平的变化，反之亦然。 一组照明装置可以包括一个或多个照明装置。

    Abstract: 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.

    Abstract: Systems and methods related to lighting fixtures for solid-state light sources are disclosed. In one embodiment, a lighting fixture includes a driver module and a communications module. The driver module is configured to execute driver program code, which causes the driver module to generate a drive output that drives one or more solid-state light sources. To provide updates, the communications module is configured to receive updated driver program code from a remote device and send the updated driver program code to the driver module. The driver module is configured to erase the driver program code and write the updated driver program code received from the communications module to memory. In this manner, updates can be provided to the lighting fixture without having to remove the lighting fixture from a support structure.

    Abstract: The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.
