摘要:
A light emitting diode (LED) lighting unit including power supply housing accommodating a power supply and an LED array housing defining an internal compartment and a lens sealing the internal compartment. A different respective LED array is mounted on at least one of a number of common printed circuit boards accommodated within the internal compartment. The different LED arrays provide different illumination, controlling one or more illumination features such as beamwidth, color and color temperature. Physical isolation is also provided between the LED array housing and the power supply housing to allow for controlled or otherwise restricted access to one or more of the different housings. In at lest some embodiments, one or more of the LED array housing and power supply housing are configured with a centrally located chimney, drawing in cooling air from a space provided between the to housings to facilitate cooling of the lighting unit.
