Abstract: A trim assembly includes a rimless trim, a reflector coupled to the rimless trim, and an optical lens disposed on the reflector. Further, the trim assembly includes a lens holder having pressure tabs formed on an inner surface thereof. The lens holder is disposed in the trim assembly such that the pressure tabs engage the optical lens to releasably seal the optical lens to the reflector for preventing entry of water. The lens holder stretches sideways to release the seal and at least partially separate the optical lens form the reflector when a force is applied on the optical lens. The partial separation between the optical lens and the reflector exposes a surface of the reflector that provides a grip to remove the trim assembly comprising the rimless trim from a mounting surface when the trim assembly is recess mounted in a mounting surface.

Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine. To facilitate thermal dissipation, a heat sink is disposed proximate to the back reflector. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.
