Abstract

A lighting strip for illuminating domestic stairways at the stair riser and stair tread that is both safe and relatively inexpensive. The device provides a lighting strip for supplying low level lighting in staircases or the like having, a means for providing a low level regulated voltage output from an ac voltage supply, a plurality of light means, a housing means for receiving and holding the light means, and the housing means is adapted to be installed under the juncture of a stair riser and stair tread, and connector means connects the light means to the low level voltage output.

Claims

1. A lighting device for providing low level lighting in staircase or the like comprising:

means for providing low level voltage output from an ac voltage supply;

a plurality of light sources;

a stranslucent diffuser;

housing means for receiving and holding said light sources;

said housing means including a rigid plastic base clip having a front portion for receiving said translucent diffuser thereon, said diffuser having peripheral edges formed for cooperation with mating means on said front portion of said base clip for removably attaching said diffuser to said base clip and a flat back portion for installing said base claip to a stair riser and stair tread on a staircase to provide illumination thereof;

connector means for connecting said light sources to said low level voltage output supply.

2. A device as defined in claim 1, said plurality of light sources are light emitting diodes.

3. A device as defined in claim 2, wherein said light emitting diodes include a current limiting means connected in series with said light emitting diodes.

4. A device as defined in claim 3, said current limiting means is a resistor.

5. A device as defined in claim 3, said light emitting diodes and said current limiting resistor being mounted on a circuit board means.

6. A device as defined in claim 1, said base clip having grooves moulded therein said grooves for slidably receiving a carrier for said light sources.

7. A device as defined in claim 1, said low level voltage output being switchable to selectively output a plurality of voltages.

8. A device as defined in claim 4, said base clip having grooves moulded therein said grooves for slidably receiving a carrier for said light sources.

9. A lighting strip kit for providing low level lighting under staircase risers or the like comprising:

a dc power supply;

a lighting bar having a plurality of ligh emitting diode light sources;

housing means for receiving and holding said light sources;

said housing means including a translucent diffuser, and a rigid plastic base clip having a front portion for receiving said translucent diffuser thereon, said diffuser having peripheral edges formed for cooperation with mating means on said front portion of said base clip for removably attaching said diffuser to said base clip and a flat back portion for installing said base clip in proximity to a stair riser and stair thread of a strircase to provide illumination thereof;

a power cord for electrically connecting said dc power supply to said light bar;

means for attaching said power cord to said light bar;

means for attaching said light bar to a surface.

10. A lighting device for providing low level lighting in staircases or the like comprising:

means for providing low level voltage output from an ac voltage supply;

a plurality of light emitting diodes connected in series with a current limiting resistor; and

said diodes and resistor mounted on a circuit board;

said housing means including a translucent diffuser, and a rigid plastic base clip having a front portion for receiving said translucent diffuser thereon, said diffuser having peripheral edges formed for cooperation with mating means on said front portion of said base clip for removably attaching said diffuser to said base clip and a flat back portion for installing said base clip in proximity to a stair riser and stair tread of a staircase to provide illumination thereof;

connector means adapted to be attached to said circuit board for electrically connecting said light emitting diodes to said low level voltage output.
