Abstract

A lighting fixture can be upgraded from utilizing a fluorescent-based light source to utilizing a light source based on light emitting diode (LED) technology. The upgrade can be completed while the fixture is mounted at an installation, or the fixture can be taken down temporarily during the upgrade. One or more fluorescent tubes in the fixture can be removed and replaced with an LED-based light engine. The light engine can include LEDs, an LED driver, and a lightguide, which may be slab-shaped. The LEDs can couple light into the lightguide, and the lightguide can distribute the coupled light. A bracket system can mount the new light engine to a frame of the lighting fixture. If the lighting fixture has a ballast, the ballast can remain attached to the fixture frame during and after the upgrade or be removed, for example.
