Abstract
A lighting module includes a heat sink with a sidewall and a partition defining two cavities, a LED light source disposed in one cavity to emit light, a driver module disposed in the other cavity with driver circuitry to provide electrical power to the light source, and an optical assembly to provide a desired emission profile. The optical assembly is field-changeable and includes a cover lens with snap-fit connectors to facilitate removal and replacement. The optical assembly further includes either a reflector coupled to the cover lens or an optical lens coupled to the heat sink via an optic holder. In some examples, the driver circuitry facilitates dimming of the light source. The heat sink also dissipates heat generated by the light source and the driver circuitry to maintain desired operating temperatures and thereby facilitate increased light output.
