Abstract

A beacon light member including a housing configured to be attached to a base member of a beacon light, the base member of the beacon light configured to utilize an incandescent light source. A power supply contained in the housing is configured to electrically connect to a power point in the base member. At least one light emitting diode (LED) light source is contained in the housing. A beacon light including a first base member, a second member, and at least one incandescent light source can also be retrofit. Under the retrofitting method, the at least one incandescent light source is removed, the second member is removed, and the second member is replaced with a beacon light module including at least one light emitting diode (LED) light source.

Claims (33)

1. A method for retrofitting a beacon light including a first base housing member, a second member formed as a housing, and at least one incandescent light source provided in the first base housing member, the method comprising:

(a) removing the at least one incandescent light source;

(b) completely removing the second member formed as a housing; and

(c) replacing the second member with a beacon light module formed as a housing including at least one light emitting diode (LED) light source, the beacon light module including a base plate adapted to the first base housing member such that the beacon light module fits on top of, without entering into, the first base housing member.

2. A method according to claim 1 , wherein the at least one incandescent light source includes first and second incandescent light sources, the first light incandescent source provided in the first base member and the second incandescent light source provided in the second member, and the removing (a) removes both of the first and second incandescent light sources.

3. A method according to claim 2 , wherein the beacon light module comprises:

(a) a housing configured to be attached to the first base member of the beacon light;

(b) a power supply contained in the housing and configured to be electrically connected to a power point in the base member; and

(c) the least one LED light source contained in the housing.

4. A method according to element 3 , wherein the at least one LED comprises plural LEDs provided in different individual LED modules.

5. A method according to claim 4 , wherein the beacon light module further comprises:

(d) a window surrounding the at least one LED.

6. A method according to claim 4 , wherein the beacon light module further comprises:

(d) a window surrounding the different individual LED modules.

7. A method according to claim 1 , wherein the beacon light module comprises:

(a) a housing configured to be attached to the first base member of the beacon light;

(b) a power supply contained in the housing and configured to be electrically connected to a power point in the base member; and

(c) the least one LED light source contained in the housing.

8. A method according to claim 7 , wherein the at least one LED comprises plural LEDs provided in different individual LED modules.

9. A method according to claim 8 , wherein the beacon light module further comprises:

(d) a window surrounding the different individual LED modules.

10. A method according to claim 7 , wherein the beacon light module further comprises:

(d) a window surrounding the at least one LED.

11. A method for retrofitting a beacon light including a first base housing member, a second member formed as a housing, and at least one incandescent light source provided in the first base member, the method comprising:

(a) removing the at least one incandescent light source from the first base member;

(b) completely removing the second member formed as a housing; and

(c) replacing the second member with a beacon light module as a housing including at least one light emitting diode (LED) light source, the LED light source connecting to a power point in the first base member through a wire connection, the beacon light module including a base plate adapted to the first base housing member such that the beacon light module fits on top of, without entering into, the first base housing member.

12. A method according to claim 11 , wherein the at least one incandescent light source includes first and second incandescent light sources, the first light incandescent source provided in the first base member and the second incandescent light source provided in the second member, and the removing (a) removes both of the first and second incandescent light sources.

13. A method according to claim 11 , wherein the at least one LED light source comprises plural LEDs provided in different individual LED modules.

14. A method according to claim 13 , wherein the beacon light module comprises:

a window surrounding the different individual LED modules.

15. A method according to claim 11 , wherein the beacon light module comprises:

a window surrounding the at least one LED.
