`
`ABSTRACT
`
`
`
`A lighting device includes a heat sink having fins on a first
`
`
`
`
`
`
`
`
`
`
`
`side and a mounting surface of a second side opposite the
`
`
`
`
`
`
`
`
`
`
`first side, a substrate attached to the mounting surface, a
`
`
`
`
`
`
`
`
`
`
`number of LEDs attached to the substrate, and a single
`
`
`
`
`
`
`
`
`
`
`transparent substrate with a number of optical elements,
`
`
`
`
`
`
`
`
`each optical element overlying an associated one of the
`
`
`
`
`
`
`
`
`
`LEDs. The device configured to direct light from the LEDs
`
`
`
`
`
`
`
`
`
`
`towards an area in a manner that does not create hot spots or
`
`
`
`
`
`
`
`
`
`
`
`
`result in dead spots on the area regardless of whether all of
`
`
`
`
`
`
`
`
`
`
`
`
`the LEDs of the plurality of LEDS or some of the LEDs of
`
`
`
`
`
`
`
`
`
`
`
`
`
`the plurality of LEDs are functional.
