Abstract

A night lighting device includes a battery powered motion activated lighting unit enclosed within a housing. The housing has walls with light apertures permitting light to escape and provide low level floor illumination. A front panel is pivotally attached to the housing. The front panel has an open peripheral frame and a rear wall set back from an edge of the frame. The open frame extends forwardly from and surrounds the rear wall. The rear wall includes light apertures and a sensor aperture. The open frame focuses the directivity of the motion sensor pattern due to the set back of the rear wall. The top overhang and side extensions of the frame prevent the motion sensing field from dispersing upwardly and laterally. Additionally, a kit is provided which includes the motion activated lighting device, a separate motion sensing lighting unit, and other components.

a light source disposed within the housing; and

a motion sensor disposed inside the housing,

wherein the light source and motion sensor are electrically connected such that the light source is turned on only when motion is detected by the motion sensor in the darkened room environment, and

wherein a sensor aperture is defined through one of said front, rear, left or right sides to permit a sensing field to be defined exteriorly of said housing for said motion sensor.

2. The apparatus of claim 1,

wherein said top, bottom, front, rear, and left and right sides are defined by respective top, bottom, front, rear, and left and right side walls;

wherein said top wall has a light reflective interior surface and said light source is oriented inside said housing to direct its emitted light onto said reflective interior surface; and

wherein said reflective interior surface redirects the emitted light in a downward angle through said light apertures to provide low level illumination on a floor surface in the vicinity of housing.

3. The apparatus of claim 2, wherein said light apertures and the orientation of said light source are configured to prevent upward emission of light within the darkened room environment.

4. The apparatus of claim 2,

wherein said reflective interior surface is a mirror which entirely covers the inside surface of the top wall, and

wherein the emitted light from said light source is directed upwardly towards said mirror and then reflected downwardly and transversely through said light apertures so as to exit the housing downwardly and outwardly along the floor surface.

5. The apparatus of claim 1,

wherein the front of the housing is defined by a front panel connected to one of the housing sides, the front panel comprising an open peripheral frame portion with a rear wall portion set back from an edge of the front peripheral frame portion.

6. The apparatus of claim 5,

wherein said sensor aperture is defined through said rear wall portion, and

wherein said frame portion focuses the motion sensing field of the motion sensor in a direction which is only along a floor surface of the darkened room environment.

7. The apparatus of claim 5, wherein said open peripheral frame portion extends forwardly from and surrounds the rear wall portion and includes:

a top overhang which prevents the motion sensing field from dispersing upwardly exteriorly of said housing, and

side extensions which prevent the motion sensing field from dispersing laterally exteriorly of said housing.

8. The apparatus of claim 2, wherein said housing further includes support structure in the form of a raised platform located on an inside surface of the bottom wall to securely hold the light source in place within the interior of the housing.

9. The apparatus of claim 8, wherein said support structure comprises one of a magnetically permeable metal plate and a magnet sandwiched between an upper support member and a lower support member.

10. The apparatus of claim 9,

wherein said upper support member includes an opening extending therethrough to provide access to said metal plate or said magnet recessed beneath the upper support member.

11. The apparatus of claim 9,

wherein the light source further includes a base having one of a magnet and a magnetically permeable metal plate secured to a bottom surface of the base, and

wherein the base has a configuration which fits within said opening so that magnetic attraction between the magnet and the metal plate holds the light source securely in the housing within the opening.

12. The apparatus of claim 10,

wherein said light source and the motion sensor form a single battery powered motion actuated lighting unit, and

wherein the magnetic attraction holds said lighting unit securely in place within the opening such that the motion sensor is aligned with the sensor aperture and light from the lighting unit is directed towards said reflective surface.

13. The apparatus of claim 5,

wherein said front panel is pivotally connected to one of the housing sides and is rotatable between an open position to provide access to the interior of said housing and a closed position, and

wherein said rear wall portion includes a locking mechanism to securely hold the front panel in its closed position.

14. The apparatus of claim 13,

wherein said rear wall portion has at least one hole extending though a lower portion thereof that aligns with a similar hole in the lower support member,

wherein said locking mechanism extends through the hole in said wall portion and engages said hole in the lower support member to secure the front panel of said housing in its closed position, and

wherein the engagement of said locking mechanism with said hole in the lower support member functions to effectively child-proof the housing by making it difficult to gain easy access to the light source disposed within the interior of the housing.

15. A lighting system for responding to motion by a person in a darkened room environment by providing sufficient light to enable that person to negotiate the environment, said system comprising:

a first apparatus as defined in claim 1, wherein said first apparatus is positioned on a floor surface under or adjacent a side of a bed such that the motion sensor, in response to detected motion of a person placing a foot on or near the floor surface of the darkened room environment, activates the light source to provide low level illumination of the floor surface near and beyond the side of the bed.

16. The lighting system of claim 15, further comprising a second apparatus as defined in claim 1:

wherein the second apparatus is positioned on the floor surface in close proximity to said first apparatus such that the motion sensor of said second apparatus, in response to detected motion of a person walking along the floor surface of the darkened room environment, activates its light source to provide a low to the floor illuminated path from the bed to another location in the darkened room environment, and

wherein the motion sensor of the first apparatus and the second apparatus keeps the light source of its respective apparatus activated only as long as motion is detected within the sensor'"'"'s defined sensing field.
