Abstract

A reading lamp is constructed with electronic lamps which offer an opportunity to provide a variety of colors and shades of white light with a minimum of emitted heat. The electronic lamps can be disposed in an alternating pattern about an incandescent lamp or concentric rings of electronic lamps of different colors can be provided.

Claims

1. A reading lamp for illuminating a surface comprising

a housing;

a first array of electronic lamps mounted in said housing for emitting a first colored light;

a second array of electronic lamps mounted in said housing for emitting a second colored light; and

means connected to said arrays of lamps to control the intensity of light emitted from each array while permitting simultaneous emission of light from each array.

2. A reading lamp as set forth in claim 1 wherein said first array of lams and said second array of lamps are connected in an alternating series arrangement and in series with said means.

3. A reading lamp as set forth in claim 1 wherein said first array of lamps emit red light and said second array of lamps emit green light.

4. A reading lamp as set forth in claim 1 which further comprises a light diffusing cover mounted in said housing over said lamps to diffuse light emitted therefrom.

5. A reading lamps as set forth in claim 1 wherein each said array of lamps is disposed in a ring and in concentric relation to the other of said array of lamps.

6. A reading lamp as set forth in claim 5 wherein said means includes a first rheostat connected in series to one of said arrays and a second rheostat connected in series with the other of said arrays.

7. A reading lamp as set forth in claim 1 which further comprises a panel in said housing mounting said arrays of lamps therein.

8. A reading lamp as set forth in claim 7 wherein said panel includes a plurality of reflector surfaces, each said surface being disposed about a respective lamp to reflect light therefrom.

9. A reading lamp as set forth in claim 1 further comprising an incandescent lamp in said housing for emitting incandescent white light.

10. A reading lamp as set forth in claim 9 further comprising a rheostat connected in series with said incandescent lamp to control the intensity of light emitted therefrom.

11. A reading lamp as set forth in claim 10 further comprising a master on-off switch connected to said arrays of lamps and said incandescent lamp to selectively actuate said arrays of lamps and said incandescent lamp simultaneously.

12. A lighting fixture comprising

a housing having an open face;

an incandescent lamp mounted in said housing for emitting incandescent light from said face;

a first switch rheostat connected in series with said lamp to control the intensity of emitted light;

a first array of electronic lamps mounted in said housing for emitting red light from said face;

a second switch rheostat connected in series with said first array to control the intensity of emitted red light;

a second array of electronic lamps mounted in said housing for emitting green light from said face; and

a third switch rheostat connected in series with said second array to control the intensity of green light.

13. A lighting fixture as set forth in claim 12 which further comprises a master on-off switch connected to said rheostats to simultaneously actuate said lamps.

14. A lighting fixture as set forth in claim 12 which further comprises a light diffusing cover mounted in said face of said housing over said lamps to diffuse light emitted therefrom.

15. A lighting fixture as set forth in claim 12 wherein each array is a ring concentric to said incandescent lamp.

16. A lighting fixture as set forth in claim 12 wherein each array is a ring concentric to said incandescent lamp and to the other array.

17. A lighting fixture as set forth in claim 12 which further comprises an adjustable mount mounting said housing thereon.

18. A lighting fixture comprising

a housing having an open face;

an incandescent lamp mounted in said housing for emitting incandescent light from said face;

a first switch rheostat connected in series with said lamp to control the intensity of emitted light;

a first array of electronic lamps mounted in said housing for emitting colored light from said face; and

a second switch rheostat connected in series with said first array to control the intensity of emitted colored light.

19. A reading lamp for illuminating a surface comprising

a housing having an open face;

a first array of electronc lamps mounted in said housing for emitting red light from said face;

a first rheostat connected in series with said first array to control the intensity of emitted red light;

a second array of electronic lamps mounted in said housing for emitting green light from said face;

a second rheostat connected in series with said second array to control the intensity of green light; and

a third rheostat connected in series with said first and said second rheostats to simultaneously control said first and said second rheostats.

20. A reading lamp for illuminating a surface comprising

a housing having an open face;

an array of electronic lamps mounted in said housing for emitting light from said face to illuminate the surface;

means connected with said array to control the intensity of light emitted onto the surface; and

a light diffusing cover mounted in said face of said housing over said lamps to diffuse light emitted therefrom.

21. A lighting fixture comprising

a housing;

an incandescent lamp mounted in said housing for emitting incandescent light therefrom; and

at least one array of electronic lamps mounted in said housing for emitting colored light therefrom to provide color discrimination for reading multicolor materials.

22. A lighting fixture as set forth in claim 21 which further comprises means connected in series with said incandescent lamp to control the intensity of emitted light.

23. A lighting fixture as set forth in claim 21 which further comprises means connected in series with said array of electronic lamps to control the intensity of light emitted.
