Abstract

An annunciator is provided. The annunciator includes a parabolic reflector formed from an insulating material, a reflective layer of metal disposed on a surface of the reflector, a high voltage strobe lamp disposed at a focal point of the reflector with a set of conductors of the strobe lamp extending through a center aperture of the reflector and a portion of the reflector proximate the aperture devoid of metallization.

Claims

1. A device comprising:

a parabolic reflector formed from an insulating material;

a reflective layer of metal disposed on a surface of the reflector;

a strobe lamp disposed at a focal point of the reflector with a set of conductors of the strobe lamp extending through a center aperture of the reflector; and

a portion of the reflector proximate to and surrounding the aperture that is devoid of metallization.

2. The device as in claim 1 wherein the strobe lamp further comprises a Xenon bulb.

3. The device as in claim 1 further comprising a printed circuit board that supports the reflector and strobe lamp.

4. The device as in claim 1 further comprising an annunciator for a security system.

5. The device as in claim 1 wherein the set of conductors further comprises two conductors and portion is oblong with a conductor extending through each end of the oblong-shaped portion.

6. The device as in claim 1 wherein the parabolic reflector defines a parabola in three dimensions.

7. A device comprising:

a shaped reflector formed from an insulating material;

a reflective layer of metal disposed on a surface of the reflector;

a lamp disposed at a focal point of the shaped reflector with a set of conductors of the lamp extending through a center aperture of the reflector; and

a portion of the reflector proximate the aperture devoid of metallization.

8. The device as in claim 7 wherein the shape of the reflector is parabolic.

9. The device as in claim 7 wherein the lamp is strobe lamp.

10. The device as in claim 9 wherein the strobe lamp further comprises a Xenon bulb.

11. The device as in claim 7 further comprising a printed circuit board that supports the reflector and strobe lamp.

12. The device as in claim 7 further comprising an annunciator for a security system.

13. The device as in claim 7 wherein the set of conductors further comprises two conductors and the portion is oblong with a conductor extending through each end of the oblong-shaped portion.

14. The device as in claim 7 wherein the parabolic reflector defines a parabola in a single dimension

15. A device comprising:

a collimating reflector formed from an insulating material;

a reflective layer of metal disposed on a surface of the reflector;

a high voltage lamp disposed at a focal point of the collimating reflector with a set of conductors of the strobe lamp extending through a center aperture of the reflector; and

a portion of the reflector proximate the aperture devoid of metallization.

16. The device as in claim 15 wherein the lamp is strobe lamp.

17. The device as in claim 16 wherein the strobe lamp further comprises a Xenon bulb.

18. The device as in claim 15 further comprising an annunciator for a security system.

19. The device as in claim 15 wherein the set of conductors further comprises two conductors and aperture is oblong with a conductor extending through each end of the oblong-shaped aperture.

20. The device as in claim 15 wherein the parabolic reflector defines a parabola in three dimensions.
