## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a combination under-cabinet LED fixture and raceway which is comprised of an upper housing, a lower housing, and a raceway cover. Even more particularly, the instant invention relates to a fixture and raceway wherein the upper housing and lower housing may be snap fitted together to create an LED fixture and wherein the raceway cover could be snap fitted to the upper housing to create a raceway. Still more particularly, a modified embodiment is disclosed wherein the under-cabinet LED fixture and raceway is comprised of two parts.
2. Description of the Related Art
Under-cabinet lighting is frequently used in kitchens, laundry rooms, etc. In recent years, LEDs have become very popular forms of under-cabinet lighting. A problem exists in providing a mounting means or an enclosure for the LEDs as well as providing wire chasers or raceways for the LED fixtures and associated wiring. In the past, LED fixtures have been provided but those fixtures have been unable to conveniently provide wiring chases or raceways. Further, wiring chases and raceways have been provided but those wiring chases and raceways are not ideally suited as LED fixtures. In other words, a person had to separately purchase LED fixtures and raceways.
SUMMARY OF THE INVENTION
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
A combination under-cabinet LED fixture and raceway is described which is comprised of an elongated upper housing, an elongated lower housing and an elongated raceway cover. The upper housing includes a base portion having first and second side edges, a top surface and a bottom surface with first and second side walls extending downwardly from the base portion adjacent the first and second side edges thereof respectively. The base portion of the upper housing is adapted to be secured to a cabinet thereabove. Each of the side walls of the upper housing have upper and lower ends and inner and outer surfaces. Each of the outer surfaces of the first and second side walls of the upper housing have alternating, horizontally extending ridges and grooves formed therein.
The elongated lower housing has upper and lower ends, a first side and a second side. The lower housing has first and second side walls at its upper end which have inner and outer surfaces. Each of the inner surfaces of the first and second side walls of the lower housing have alternating, horizontally extending ridges and grooves formed therein which are adapted to frictionally receive the first and second side walls of the upper housing so that the ridges and grooves of the side walls of the lower housing and the ridges and grooves of the side walls of the upper housing may be snapped together to selectively secure the lower housing to the upper housing and to define a wire chase or passageway therebetween. The lower housing member has an elongated opening formed therein which extends upwardly thereinto its lower end. A light emitting source is positioned in the lower housing which directs light downwardly through the elongated opening in the lower housing member. A lens is snap fitted into the lower end of the lower housing below the light emitting source.

For purposes of description, lower housing 14 will be described as having an upper end 48 and a lower end 50. Web 52 extends between side walls 54 and 56, as seen in FIG. 1. The inner surfaces of side walls 54 and 56 above web 52 are each provided with alternating, horizontally extending ridges and grooves formed therein which are generally referred to by the reference numerals 58 and 60 respectively. The side walls 54 and 56 of lower housing 14 are adapted to receive the side walls 32 and 34 of upper housing 12 with the ridges and grooves 36 and 38 of side walls 32 and 34 frictionally engaging the ridges and grooves 58 and 60 of side walls 54 and 56 respectively to snap-fit lower housing 14 to upper housing 12 as seen in FIG. 3 thereby creating a wire chase or passageway 62.
An elongated opening 64 extends upwardly into lower housing 14 to define spaced-apart leg portions 66 and 68 on opposite sides thereof. A pair of elongated grooves or slots 70 and 72 are formed in the inner surfaces of leg portions 66 and 68 respectively which longitudinally slidably receive the side edges of the substrate assembly 18 which includes a circuit board 74 having a plurality of LEDs 76 mounted thereon. The lower inner ends of leg portions 66 and 68 are provided with elongated grooves or slots 78 and 80 formed therein respectively which receive the side edges of lens 20 in a snap-fit relationship.
Raceway cover 16 includes a bottom wall 82 having side walls 84 and 86 extending upwardly therefrom in a spaced-apart relationship. The inner surfaces of side walls 84 and 86 each have alternating, horizontally extending ridges and grooves 88 and 90 formed therein respectively which are adapted to frictionally engage the ridges and grooves 36 and 38 of upper housing 12 respectively when lower housing 14 is not being utilized and it is desired to create a raceway 92 utilizing upper housing 12 and raceway cover 16.
Preferably the housings 12 and 14 and the raceway cover 16 are formed from extruded aluminum. It is preferred that the height of upper housing 12 be approximately 3⁄8 inch with the height of lower housing 14 being approximately 5⁄8 inch. It is also preferred that the height of raceway cover 16 be approximately 3⁄8 inch.
Thus, the lower housing 14 may be secured vertically adjustably secured to the upper housing 12 to create an under-cabinet LED fixture. In the alternative, raceway 16 may be vertically adjustably secured to upper housing 12 to create a raceway.
A modified form of the combination under-cabinet LED fixture and raceway 110 is illustrated in FIGS. 6-8 which is comprised of two parts or components as opposed to the three-part combination LED fixture and raceway of FIGS. 1-5.
The modified combination under-cabinet LED fixture and raceway 110 includes an elongated upper housing 112, an elongated lower housing 114, substrate assembly 116 and lens 118. Substrate assembly 116 includes a circuit board (CB) and a plurality of LEDs 117. For purposes of description, upper housing 112 will be described as having a base portion 120 having side edges 122 and 124, a top surface 126, and a bottom surface 128. This portion 120 has a pair of spaced-apart side walls 130 and 132 extending downwardly therefrom adjacent side edges 122 and 124 respectively. The lower inner surface of side wall 130 is provided with a pair of horizontally extending ridges 134 and 136 formed thereon with a groove 138 formed therebetween. The lower inner surface of side wall 132 is provided with a pair of horizontally extending ridges 140 and 142 formed therein with a groove 144 formed therebetween. Base portion 120 is preferably provided with a plurality of spaced-apart holes or openings 145 formed therein adapted to receive screws therein to enable housing 112 to be secured to the underside of a cabinet having a face board extending downwardly from the front edge thereof, such as illustrated in FIGS. 2 and 3.
For purposes of description, lower housing 114 will be described as including a base portion 146 having spaced-apart side walls 148 and 150 extending therefrom. The outer surfaces of side walls 148 and 150 each have a plurality of horizontally extending alternating ridges and grooves formed therein which are referred to by the reference numerals 152 and 154 respectively. The inner surfaces of side walls 148 and 150 are each provided with an elongated groove formed therein, referred to by the reference numerals 156 and 158 respectively, adapted to receive the side edges of the lens 118. Substrate assembly 116 is secured to the inner surface of base portion 146 of lower housing 114 as illustrated in the drawings.
FIG. 6 illustrates the lower housing member 114 inserted into the upper housing 112 between the side walls 130 and 132 thereof to form a raceway 160. The alternating ridges on the side walls 148 and 150 of lower housing 114 are adjustably received within the grooves 138 and 144 respectively to adjustably yieldably maintain the lower housing 114 within the upper housing 112. When the upper and lower housing 112 and 114 are being used as a raceway, the substrate and lens will normally not be secured to the inner surface of the base portion 146 nor will there be a lens inserted into the grooves or slots 156 and 158.
When it is desired to create an LED fixture, the lower housing 114 is inserted into the upper housing 112 between the walls 130 and 132 thereof so that the base portion 146 is uppermost with the side walls 148 and 150 extending downwardly therefrom, as illustrated in FIG. 8. The alternating ridges on the side walls 148 and 150 are received by the grooves 144 and 138 respectively to yieldably maintain the lower housing 114 within the upper housing 112. When the lower housing is in the position of FIG. 8, the substrate assembly 116 will be secured to the underside of base portion 146 as will the LEDs 117 so that light will be directed downwardly therefrom through the lens 118 positioned in the grooves 156 and 158.
Thus, it can be seen that a unique combination LED fixture and raceway is provided which includes an upper housing and a lower housing with the lower housing being inserted into the upper housing in one manner to form a raceway and which may be inserted into the upper housing 112 in another manner to provide an LED fixture.
Thus, it can be seen that the embodiment of FIGS. 6-8 accomplishes at least all of its stated objectives.
