Abstract
A lighting apparatus includes an LED-based lighting fixture having a housing and a gasketed face panel (e.g., a lens, diffuser or other optical cover), a protective flexible sleeve removably fitted over the housing, and a bezel for sealably retaining the gasketed face panel against the housing and connected to the housing with a non-adhesive connector, so that it can be readily removed therefrom. The flexible sleeve is made from a thermoplastic material and is removably secured over the lighting fixture by a compressive force. Applications for such lighting apparatus include theatrical and rental lighting, where fixtures are exposed to rigors of frequent handling.

23. A method for enabling repairs or maintenance of an LED-based lighting apparatus, the apparatus comprising (i) a housing having at least one LED-based lighting unit disposed therein;
- (ii) a lens associated with the housing for transmitting light emitted by the at least one LED-based lighting unit; and
(iii) a bezel removably attached to the housing, the method comprising;
rotating the bezel about a pivot point in a direction away from the housing;
removing the lens, thereby providing access to the at least one LED-based lighting unit of the lighting apparatus;
replacing the lens or placing a replacement lens; and
rotating the bezel about the pivot point in a direction toward the housing to sealably secure the lens against the housing. - View Dependent Claims (24)
