Abstract:
An electronics enclosure has a mains input and a lamp output. A power factor correction circuit (204) is installed in the enclosure, to provide a DC output voltage. An inverter (208) is also installed in the enclosure. Control electronics (310) is also installed in the enclosure to control the inverter, and to receive a selection of lamp load type made manually by a user via a user interface on an outside face of the enclosure. The same lamp output can thus alternatively drive, for example, a high pressure sodium lamp and a metal halide lamp, as indicated by the selection.

Abstract:
A number of elements are integrated within an electronics enclosure. A non-inverting buck-boost converter is to operate in the continuous conduction mode designed to provide an average power of more than 200 watts at its DC output. A power bus is coupled to the DC output. Multiple inverter circuits are coupled to the power bus in parallel, each inverter circuit having a respective output to drive a respective electric discharge lamp. Other embodiments are also described and claimed.
