A radiation distribution system designed to produce a batwing distribution. The system may be used with radiative sources emitting in the visible spectrum or in other spectra. The system comprises a specially shaped lens disposed over a radiative source, such as an LED, for example. The lens and source are arranged between two reflector bodies, both of which have an elongated reflective surface that faces the source. The reflector bodies each have two different reflective surfaces that face outward and away from each other. The lens and both reflective surfaces work in concert to redirect a portion of the emitted radiation to create the desired batwing distribution. Several sources may be arranged linearly between a single pair of reflector bodies on a common surface to create a linear array of sources. Likewise, multiple linear arrays may be combined to form a two-dimensional array. In the two-dimensional configuration, linear arrays of sources are disposed on both sides of a reflector body, so that both of the reflective surfaces are utilized.

A lighting device employs at least one string of LEDs as a lighting source. The string of LEDs is coupled in series with a first switch, wherein the string of LEDs and the first switch are coupled between a power supply node and ground. During a normal operation mode, a system controller is configured to close the first switch to deliver a drive current to the string of LEDs from the power supply node. The system controller is further associated with a temperature sensor and is configured to detect an over-temperature condition based on information provided by the temperature sensor. Upon detecting the over-temperature condition, the system controller will open the first switch to stop the drive current from flowing through the string of LEDs.

A modular LED lighting fixture is provided, where the shape and brightness of light output from the fixture can be altered by changing LED modules and/or power supplies powering the modules within the fixture. The fixture can include a housing, a modular, removable LED module attached within the housing, and at least one modular, removable power supply attached to the housing for powering the LED module.
