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 pair of conductors of the strobe lamp extending through a center aperture of the reflector; and

a oblong-shaped portion of the reflector proximate to and surrounding the aperture that is devoid of metallization and with a conductor of the pair of conductors that extract through each end of the oblong-shaped portion.

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 parabolic reflector defines a parabola in three dimensions.

6. 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 two conductors of the lamp extending through a center aperture of the reflector; and

an oblong-shaped portion of the reflector proximate the aperture devoid of metallization and with a conductor of the two conductors extending through each end of the oblong-shaped portion.

7. The device as in claim 6 wherein the parabolic reflector defines a parabola in a single dimension.

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. 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 two conductors of the strobe lamp extending through a center aperture of the reflector; and

an oblong-shaped portion of the reflector proximate the aperture devoid of metallization with a conductor of the two conductors extending through each end of the oblong-shaped portion.

14. The device as in claim 13 wherein the parabolic reflector defines a parabola in three dimensions.

15. The device as in claim 13 further comprising an annunciator for a security system.

16. The device as in claim 13 wherein the lamp is strobe lamp.

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