Abstract

The present invention is directed to an improved signal light. The signal lamp comprising a base and at least one hollow cylindrical light transmitting column attached to the base. A light source in contained in the column wherein the light source comprises: a mounting plate; a globe reflector element attached to the mounting plate; and at least one LED directed toward the reflector element.

Claims

1. A signal lamp comprising:

a base;

at least one hollow cylindrical light transmitting column attached to said base;

a light source in said column;

said light source comprises;

a mounting plate;

a globe reflector element attached to said mounting plate; and

at least one LED directed toward said globe reflector element.

2. The signal lamp of claim 1 comprising a multiplicity of LEDs directed toward said globe reflector element.

3. The signal lamp of claim 2 wherein said LEDs are arranged in a plane containing said globe reflector element.

4. The signal lamp of claim 3 wherein said plane is perpendicular to an axis of said cylindrical light transmitting column.

5. The signal lamp of claim 1 comprising a multiplicity of cylindrical light transmitting columns.

6. The signal lamp of claim 1 wherein said cylindrical transmitting column is a cylindrical parallel convex magnifier.

7. The signal lamp of claim 1 wherein said cylindrical transmitting column comprises a multiplicity of parallel linear convex lens.

8. A signal lamp comprising:

a base;

at least one hollow cylindrical light transmitting column attached to said base;

a light socket within said column; and

a light source comprising;

a mounting plate;

a globe reflector attached to said mounting plate;

at least one LED attached to said mounting plate directed towards said globe reflector;

a light socket base electrically connected to said LED;

wherein said light socket base is receivable within said light socket.

9. The signal lamp of claim 8 comprising a multiplicity of LEDs wherein said LEDs are directed towards said globe reflector.

10. The signal lamp of claim 9 wherein said multiplicity of LEDs and said globe reflector are contained in a plane.

11. The signal lamp of claim 8 wherein said light socket and said light socket base are threaded.

12. The signal lamp of claim 8 wherein said cylindrical transmitting column is a cylindrical parallel convex magnifier.

13. The signal lamp of claim 8 wherein said cylindrical transmitting column comprises a multiplicity of parallel linear convex lens.

14. A light source comprising:

a mounting plate;

a globe reflector attached to said mounting plate;

a first LED attached to said mounting plate directed towards said globe reflector;

a light socket base electrically connected to said first LED.

15. The light source of claim 14 comprising a second LED attached to said mounting plate directed towards said globe reflector.

16. The light source of claim 15 comprising a third LED attached to said mounting plate directed towards said globe reflector.

17. The light source of claim 16 comprising a fourth LED attached to said mounting plate directed towards said globe reflector.

18. The light source of claim 17 wherein said first LED, said second LED, said third LED and said fourth LED form a square with said globe reflector located in said square.

19. The light source of claim 14 wherein said light socket base is threaded.
