The present disclosure relates to an optic support, and more specifically to an optic support for a light fixture.
In one independent aspect, an optic support is provided for a light fixture having a light engine secured within a housing. The optic support includes a body and a biasing member. The body includes a first portion and a second portion. The second portion is configured to engage an optic. The biasing member is coupled to the first portion of the body. The biasing member is configured to bias the body into engagement with the housing.
In another independent aspect, a light fixture includes a housing, a light engine coupled to the housing, a lens, a support, and a biasing member. The light engine includes at least one light-emitting element. The lens is positioned proximate the light-emitting element. The support is coupled to the housing and supports the lens. The biasing member releasably couples the support to the housing.
In yet another independent aspect, light fixture includes a housing, a light engine, a lens, a first support, a first leaf spring, a second support, and a second leaf spring. The housing includes a first inner surface and a second inner surface facing toward the first inner surface. The light engine is coupled to the housing and positioned between the inner surfaces. The light engine includes at least one light-emitting element. The lens is positioned proximate the light-emitting element. The first support is coupled to the first inner surface of the housing and supports the lens. The first leaf spring releasably couples the first support to the housing. The first leaf spring includes a first end, a second end, and a convex portion positioned between the first end and the second end. The convex portion engages a groove on the first inner surface. The second support is coupled to the second inner surface of the housing and supports the lens. The second leaf spring releasably couples the second support to the housing. The spring leaf spring includes a first end, a second end, and a convex portion positioned between the first end and the second end. The convex portion engages a groove on the second inner surface.
Other aspects of the disclosure will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. Use of “including” and “comprising” and variations thereof as used herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Use of “consisting of” and variations thereof as used herein is meant to encompass only the items listed thereafter and equivalents thereof. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings.
In general, the present disclosure relates to a support for coupling an optic, such as a lens, to a light fixture housing. The support is coupled to the housing by a biasing member, and the support retains the optic against a seal.

The body 34 further includes drivers (not shown) for supplying and controlling current to the light emitter 40. The light emitter 40 is positioned on the body 34 and surrounded by the heat sink 36. In the illustrated embodiment, the light emitter 40 is a light emitting diode or LED, although in other embodiments, the light emitter 40 may be another type of light emitter. The electrical connector(s) 44 is positioned on an end of each body 34. The electrical connector 44 on an end of one of the housing portions 14, 16 can be in electrical communication with an electrical connector 44 on an end of the other of the housing portions 14, 16. The electrical connectors 44 provide electrical communication between separate light engines 18.
In the illustrated embodiment, each housing portion 14, 16 includes a first internal or side surface 68 and a second internal or side surface 72. The first internal surface 68 and the second internal surface 72 each have an internal ledge 64. Each internal ledge 64 is positioned proximate a lower end 76 of the housing 14, 16 proximate the lens 24. In some embodiments, the internal ledges 64 extend the length of the housing 12.

A tool (e.g., a thin, flat blade—not shown) may be inserted into the interior 48, proximate the first side surface 68 or the second side surface 72, while the supports 28 and lens 24 are coupled to the housing portions 14, 16. The blade may bias either surface 68, 72 outwards (i.e., away from the light engine 18) and/or compress the spring 80, thereby spacing the spring 80 from the internal ledge 64 and providing clearance for the supports 28 and lens 24 to be removed from the housing 12 and providing access to the light engine 18.
Although aspects have been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects as described.
This application claims the benefit of prior-filed U.S. Provisional Patent Application No. 62/592,892, filed Nov. 30, 2017, the entire contents of which are incorporated by reference.
