Abstract:
An LED fixture includes multiple LED drivers and multiple LED lamps 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 the different LED lamps are driven sequentially. An optional multi-lamp LED driver concurrently drives multiple LED lamps that have been previously driven by the LED drivers.
