Description

FIELD OF THE INVENTION

The present invention relates to contemporary styled high-performance lighting fixtures having unique design features and drainage capabilities.

BACKGROUND OF THE INVENTION

While there are many lighting fixtures having various designs and illumination features, very few offer the versatility of reconfiguration, while combining high quality downlighting, uplighting, path lighting, and angled lighting. Most contemporary fixtures are generally made of extruded or case tubes, which limit access to the interior and the fixed position of the LED's adjustability, functionality, and performance.

In addition, although articulating gimbal (eyeball) lighting fixtures have been used for a long period of time in typical ceiling, i.e. downward facing, applications, they have not been applied to outdoor environments in upward facing applications, since they can hold pockets of water when articulated. This results in two major problems. First, water ingress as the fixture's lamp heats up when on and then cools when turned off, creates a vacuum that can draw water into the delicate internal electronic components and circuitry of the lamp. This results in permanent damage and failure. Second, when the fixture is articulated, standing water results which causes the accumulation of algae and the collection of dirt/debris. This diminishes light performance, beam spread and focus.

SUMMARY OF THE INVENTION

It is thus the object of the present invention to provide contemporary styled, high performance, versatile lighting fixtures which overcome the disadvantages and limitations of prior lighting fixtures.

These and other objects are accomplished by the present invention, a versatile lighting fixture which has an elongated, vertical channel member with back and opposing side walls forming a vertical passageway. A baffle member is located within passageway and extends the length of the channel member. The baffle member has an upper support member which is fixedly attached to a gimbal LED module located within the channel member. The module has wiring which extends through the passageway. A lighting fixture mount is located at the bottom of the channel. The gimbal LED module has a top trim plate member with an opening and a series of drainage grooves extending downward from the opening. When the LED lamp faces upward in the lighting fixture, water accumulating on and around the trim plate member is drained away from the module through the drainage grooves.

The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.
