Abstract

An illuminated doorbell pushbutton assembly includes a pushbutton assembly that uses a light source, or a plurality thereof to illuminate the pushbutton. The assembly also includes a user-adjustable rotating task light that can be used to direct light to a door lock, a dark step, or to provide a light for identifying keys. A reflector is rotated through an arc to direct light to the area desired by the user. The assembly further includes an electrical circuit that enables the assembly to be installed with electro-mechanical or electronic chimes.

Claims (34)

1. A circuit for an illuminated doorbell assembly having a source of electrical power and a chime assembly responsive to an electrical signal comprising:

a light source for providing illumination to said doorbell assembly;

a first diode between said source of electrical power and said light source to provide electrical power to said at least one light source; and

a doorbell pushbutton between said source of electrical power and said chime assembly for supplying electrical power thereto when depressed.

2. A circuit for an illuminated doorbell assembly as claimed in claim 1 further comprising:

a second diode in parallel with said doorbell pushbutton to supply electrical power to said chime when said doorbell pushbutton is not depressed.

3. A circuit for an illuminated doorbell assembly as claimed in claim 2 further comprising:

means for electrically decoupling said second diode from said circuit.

4. A circuit for an illuminated doorbell assembly as claimed in claim 3 wherein said means for decoupling said second diode from said circuit comprises a jumper terminal.

5. A circuit for an illuminated doorbell assembly as claimed in claim 3 wherein said means for decoupling said second diode from said circuit comprises a switch.

6. A circuit for an illuminated doorbell assembly as claimed in claim 1 wherein said light source is a light emitting diode.

7. A circuit for an illuminated doorbell assembly having a source of electrical power and a chime assembly responsive to an electrical signal comprising:

a plurality of light sources for providing illumination to said doorbell assembly;

a first diode interposed between said source of electrical power and said plurality of light sources to provide electrical power thereto; and

a doorbell pushbutton between said source of electrical power and said chime assembly for supplying electrical power thereto when depressed.

8. A circuit for an illuminated doorbell assembly as claimed in claim 7 further comprising:

a second diode in parallel with said doorbell pushbutton to supply electrical power to said chime when said doorbell pushbutton is not depressed.

9. A circuit for an illuminated doorbell assembly as claimed in claim 8 further comprising:

means for electrically decoupling said second diode from said circuit.

10. A circuit for an illuminated doorbell assembly as claimed in claim 9 wherein said means for decoupling said second diode from said circuit comprises a jumper terminal.

11. A circuit for an illuminated doorbell assembly as claimed in claim 9 wherein said means for decoupling said second diode from said circuit comprises a switch.

12. A circuit for an illuminated doorbell assembly as claimed in claim 9 further comprising a plurality of voltage dividers in series with said plurality of light sources.

13. A circuit for an illuminated doorbell assembly as claimed in claim 7 wherein said plurality of light sources are light emitting diodes.

14. A circuit for an illuminated doorbell assembly as claimed in claim 7 wherein said plurality of light sources are incandescent lamps.

15. A circuit for an illuminated doorbell assembly having a source of electrical power and a chime assembly responsive to an electrical signal comprising:

a light source for providing illumination to said doorbell assembly;

a diode disposed between said source of electrical power and said light source to provide electrical power to said at least one light source;

a doorbell pushbutton between said source of electrical power and said chime assembly for supplying electrical power thereto when depressed to actuate chime assembly.

16. A circuit for doorbell assembly having a source of electrical power and a chime assembly responsive to an electrical signal comprising:

a doorbell pushbutton between said source of electrical power and said chime assembly for supplying electrical power thereto when depressed;

a diode in parallel with said doorbell pushbutton to supply electrical power to said chime when said doorbell pushbutton is not depressed; and

means for electrically decoupling said second diode from said circuit.

17. A circuit for an illuminated doorbell assembly as claimed in claim 16 wherein said means for decoupling said diode from said circuit comprises a jumper terminal.

18. A circuit for an illuminated doorbell assembly as claimed in claim 17 wherein said means for decoupling said diode from said circuit comprises a switch.
