The present invention relates to the field of interior lighting, and, more particularly, to a light fixture suitable for mounting under hung cabinets for illuminating an underlying counter surface.
Under cabinet light fixtures are available in a number of different designs. A hung cabinet extends out over of the underlying counter surface area. Generally, the cabinet only extends out over 50% of the underlying counter surface area. Most under cabinet light fixtures are installed near the rear side of the cabinet, adequately lighting the rear portion of the underlying counter surface area. However, the counter surface area that is most utilized is the front ⅓ of the total counter surface area. Improvements to increase illumination of the underlying counter surface, and in particular, to increase illumination of the most utilized counter surface areas are desirable.
Generally, when an under cabinet light fixture is mounted to the underside of a cabinet, the light fixture makes significant contact with the cabinet surface. Depending upon the voltage of the light fixture and the number and wattage of bulbs in the fixture, significant heat can be generated when the fixture is operated. Contact between heated surfaces of the light fixture and the cabinet surface increase heat transfer from the fixture to the cabinet surface and can increase the risk of heat damage or fire. Improvements to increase cooling of the under cabinet light fixture and to lower heat transfer between the light fixture and the cabinet surface are desirable.
An embodiment of the under cabinet light fixture of this invention includes a housing having a top wall with substantially planar outer surface portions adapted to be positioned closely adjacent, spaced-apart from, and substantially parallel to a substantially planar support surface. The substantially planar support surface may extend in a substantially horizontal plane underneath a cabinet. A spaced-apart region between the substantially planar outer surface portions of the top wall and the substantially planar support surface defines an interstitial space to selectively allow air to flow into the interstitial space to enhance cooling of the light fixture in preselected under cabinet mounting positions during operation of the under cabinet light fixture. A front wall is connected to and extends downwardly from the top wall. A rear wall, positioned opposite the front wall, is connected to and extends downwardly from the top wall at an angle substantially perpendicular to the top wall. A pair of opposing end walls are connected to end portions of the top wall, the front wall, and the rear wall so that the inner surfaces of the respective walls define outer boundaries of an inner cavity. Each end wall also has an extended outer surface portion that extends upwardly above the substantially planar outer surface portions of the top wall toward the under cabinet region when positioned adjacent thereto and abuttingly contacting the under cabinet region so that inner surfaces of the respective extended outer surface portions of the pair of end walls define end peripheries of the interstitial space.
A bottom access panel is pivotally connected to the housing along a rear portion of the bottom access panel. The bottom access panel pivots between a closed operating condition when the bottom access panel extends in a plane substantially parallel to the substantially horizontal plane of the under cabinet region and thereby closes the inner cavity, and an open access condition when the bottom access panel pivots and extends downwardly from the housing and from the substantially horizontal plane to provide access to the inner cavity. The bottom access panel includes a first panel portion of non-translucent material and a second panel portion formed of translucent material. The first panel portion is positioned in the substantially parallel plane when the bottom access panel is in the closed position and the second panel portion is positioned to extend upwardly from the substantially parallel plane toward the under cabinet region at a predetermined angle from the substantially parallel plane when the bottom access panel is in the closed position.
A reflector is connected to the housing and is positioned within the inner cavity to reflect light toward the second panel portion of the bottom access panel. At least one lamp socket is connected to the housing and is positioned within the inner cavity so that when a light bulb is positioned in the at least one lamp socket and the light fixture is in an operating condition, light from the light bulb is reflected by the reflector toward and radiates through the second panel portion of the bottom access panel to thereby provide enhanced visibility of light radiating from underneath the cabinet when the light fixture is in the operating position.
So that the manner in which the features and benefits of the invention, as well as others which will become apparent, may be understood in more detail, a more particular description of the invention briefly summarized above may be had by reference to the embodiments thereof which are illustrated in the appended drawings, which form a part of this specification.

The under cabinet light fixture 21 can be configured for hard wired installation or for self-installation. For hard wired installation, typically done by an electrician, one or more knock out openings (not shown in the drawings) may be provided in a convenient location such as the rear wall 25 for passing external electrical power wiring into the inner cavity 35. For self installation, male and female electrical connectors 105, 107 respectively are provided on end walls 31, 33 as shown in
A jumper cord 114 as shown in
The counter light fixtures of this invention can be configured for use with either high voltage (e.g. 110 Volts) or low voltage (e.g. 12 Volt) lamp bulbs in lamp sockets 43. As previously indicated, in an alternate embodiment, traditional bulbs may be replaced with LEDs. For low voltage use a power transformer 119 is provided, which can be conveniently installed within the inner cavity 35, as shown in
The embodiments of the present invention offer several advantages over other under cabinet light fixtures. By providing end walls with surfaces that extend above the top wall of the housing, the under cabinet light fixture of the present invention eliminates surface contact between the top wall and the support surface and allows air to flow over the top of the housing, thereby decreasing heat transfer between the light fixture and the support surface. Additionally, by providing a bottom access panel that angles upwardly toward the support surface, the under cabinet light fixture of the present invention can reflect and radiate light toward underlying counter surfaces that previously did not receive light from the fixture, thereby providing enhanced visibility of light radiating from underneath the support surface.
In the drawings and specification, there have been disclosed a typical preferred embodiment of the invention, and although specific terms are employed, the terms are used in a descriptive sense only and not for purposes of limitation. The invention has been described in considerable detail with specific reference to these illustrated embodiments. It will be apparent however, that various modifications and changes can be made within the spirit and scope of the invention as described in the foregoing specification and as set forth in the following claims.
