This application relates to light fixtures, and, more particularly, to light fixtures with drainage systems.
Light fixtures are commonly used in both indoor and outdoor applications to provide various types of lighting. For example, flood lights may be installed to “wall wash” a building, highlight landscape or other architectural features, or project general area lighting. Such light fixtures may be installed as an up-light installation (e.g., when the light fixture is ground-mounted) or a down-light installation (e.g., when the light fixture is mounted on a pole, wall, or other structure) depending on application requirements. When light fixtures are provided outdoors, up-light installations will invariably see rain or snow on the lens of the light fixture, which may collect and undesirably affect light output. In such installations, depending on the projection angle of the light fixture, significant accumulation may remain or freeze for long periods and seriously degrade performance of the light fixture. Outdoor down-light installations may see similar accumulation of water or snow on the rear of the light fixture, which increases the likelihood that moisture enters the housing through seams of the light fixture.

While LEDs are described, it will be recognized that light fixtures may include other kinds of light sources such as fluorescent, incandescent, halogen, etc.
The housing 102 includes a front side 112 and a back side 114. The housing 102 also defines a housing chamber 116 that has an opening 118 in the front side 112. Various electronic components of the light fixture 100 such as a driver 130, light source 132, etc. may be provided in the housing chamber 116. In some examples, and as best illustrated in
In various examples, the housing 102 includes a flange 122 that includes a perimeter edge 124. In some cases, the perimeter edge 124 may be the outermost edge of the housing 102, although it need not be in other examples. The flange 122 also includes coupling apertures 125 that receive screws or bolts 105 to secure the bezel 104 relative to the housing 102. While coupling apertures 125 are illustrated, various other suitable mechanisms or components for coupling the bezel 104 relative to the housing 102 may be utilized.
In some examples, the front side 112 includes a gasket channel 126 for the gasket 110, although in other examples the gasket channel 126 may be omitted. Optionally, heat sink elements 128 (e.g., fins and/or other suitable elements) may be provided on the housing 102, although they may be omitted in other examples. The shape, profile, and/or configuration of the housing 102 and/or components of the housing 102 should not be considered limiting on the current disclosure, as in various other examples, the housing may have various other shapes, profiles, or configurations as desired. For example, in other cases, the housing 102 may be square, rectangular, circular, cylindrical, or have various other geometric shapes or profiles as desired.
As mentioned above, various electronics of the light fixture 100 may be positioned within the housing chamber 116. In the example of
The optic 106 (such as a lens, diffuser, or other suitable optic as desired) is positioned on or over the opening 118. The optic 106 can be made of any non-metallic material that permits light to exit through the optic 106, including, but not limited to, glass, polymeric materials, silicone and various other suitable materials for light distribution. As best illustrated in
The bezel 104 includes a front end 142, a rear end 144, at least one inner side wall 146, and at least one outer side wall 148. As best illustrated in
As best illustrated in
When assembled, the bezel 104 is secured to the housing 102 and the optic 106 and reflector 108 are retained between the bezel 104 and the housing 102. In various aspects, the bezel 104 is secured to the housing 102 such that the bezel 104 applies pressure onto the optic 106 to maintain the seal between the optic 106 and the housing 102. In some examples, a side profile of the bezel 104 is tapered such that the thickness of the outer side wall 148 at a top portion of the bezel 104 is different than its thickness at a bottom portion of the bezel 104. In the illustrated embodiment (see
The light fixture 100 may include various mechanisms or devices for supporting the light fixture 100 in a particular location or on a particular device. As some non-limiting examples, various mounting mechanisms that can be used with the light fixture 100 may include, but are not limited to, a mounting bracket or yoke, a slip fitter that slips over the end of a mounting pole, and/or a knuckle. In various cases, the mounting mechanisms may enable the orientation of the light fixture 100 to be adjusted (either pivotably, rotationally, or both).
The bezel 104 defines a drainage system for the light fixture 100. Through the drainage system, water or other fluids falling onto the light fixture 100 may be drained from the light fixture 100 regardless of whether the light fixture 100 is an up-light installation or a down-light installation. In various aspects, the drainage system may drain water in any installation configuration while maintaining the integrity of the sealed housing chamber 116. In various aspects, the light fixture 100 with the drainage system may achieve various environment ratings, including but not limited to an IP66 environmental rating from the International Electrotechnical Commission.
In various examples, one or more drainage notches 155 are provided along the rear edge 145 of the inner side wall(s) 146 proximate the rear end 144 of the bezel 104 (see
In some examples, and as best illustrated in
Because the weep openings 156, drainage openings 164, and drainage gap 162 are in fluid communication with each other (i.e., through the drainage channel 154), the drainage system is able to drain water from the light fixture 100 regardless of the particular configuration of the light fixture 100. It will be appreciated that air or other gaseous substances may also flow through the various gaps and openings to dry any internal surfaces to which water may be held.
One of skill in the art will appreciate that the drainage systems disclosed herein work to effectively dissipate water and other fluids from the light fixture 100 regardless of the orientation of the fixture.
