Angled emitter channel letter lighting

摘要

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.

主权项

1. A lighting unit, comprising:
a printed circuit board (PCB) comprising a front surface, a back surface and at least one tab; at least one light emitting element on said PCB; said at least one tab adapted to be bent in a direction away from said PCB to form an angled surface with respect to the PCB, wherein said at least one light emitting element is on said angled surface; and conductors electrically connected with said PCB to provide an electrical signal to said at least one light emitting element, wherein said at least one light emitting element emits light away from said PCB such that said lighting unit is configured to emit light in a substantially omni-directional pattern.
