Abstract
A lighting device may include a lens, an emitter configured to emit light through the lens, and a reflector. The reflector may define a cavity that extends from a first end to a second end of the reflector. The emitter may be received in the first end of the reflector, and the lens may be attached to the second end of the reflector. The lens may include teeth that extend from a rear surface of a rim of the lens. The reflector may include a collar at the second end, and the collar may include attachment clips that are configured to lock the teeth in place and retain the lens in attachment to the reflector.
Claims16
A lighting device comprising:
- a lens comprising a rim portion having teeth extending in a longitudinal direction from a rear surface of the rim portion, wherein each of the teeth comprises a ledge portion and a body portion that is connected to the rear surface of the rim portion via two legs;
- an emitter configured to emit light through the lens;
- and
- a reflector defining a first cavity that extends from a first end of the reflector to a second end of the reflector, the emitter received within the first cavity at the first end and the lens configured to be attached to the second end of the reflector, the reflector comprising:
- a collar that extends around the second end of the reflector, the collar comprising an outer surface that defines an outer perimeter of the second end;
- a plurality of attachment clips extending from the collar in a substantially circumferential direction, each of the plurality of attachment clips configured to engage a respective one of the teeth such that the lens is secured to the reflector;
- and
- a spring arm configured to apply a first force to on the lens when the lens is attached to the reflector such that the rim portion is pushed away from the collar, and
- wherein the ledge portion of each of the teeth is configured to contact a lower surface of respective lip portions of the collar to limit movement of the lip portions within a respective second cavity that is located between the body portion and the rear surface of the rim portion.
