Abstract
An LED fixture includes multiple LED drivers and a multi-chip LED package so that the lifetime of the fixture is a multiple of the lifetime of a conventional fixture that uses only a single LED driver. A distributed controller activates and deactivates the LED drivers so that different subsets of LEDs within the LED package are driven sequentially. An optional multi-chip LED driver concurrently drives multiple subsets of LEDs that were previously driven by the LED drivers.
