Abstract

The present embodiments provide channel letter lighting devices and/or systems. A lighting system, comprising a plurality of electrically connected lighting units, comprising conductors to provide an electrical signal to each of the units. Each of the lighting units comprise a housing, a printed circuit board (PCB) mounted within the housing and having a plurality of tabs and a plurality light emitting elements on the tabs. The tabs are angled in relation of the remainder of the PCB or housing. The electrical signal applied to the light emitting elements causes them to emit light substantially away from said housing. The lighting system further comprises a sealant within the housing filling cavities around the light emitting elements and the cavity around said PCB and a mounting mechanism for mounting the unit to a structure.
