Abstract

Apparatus and methods for an environmentally resistant germicidal lamp are disclosed. A cover may have a material resistant to at least one of dripping, light splashing, light spraying of liquid and condensation. The cover may have a first section having an opening for receiving a base of a lamp, and an inner surface for encompassing and being slightly larger than an outer cross section of the base when the first section receives the base. The cover may have a second section having an opening for receiving a socket of an electric discharge lamp fixture, and an inner surface for encompassing and being slightly larger than an outer cross section of the socket when the second section receives the socket. The cover may shield and partially enclose electrical contacts of either the base or the socket from at least one of dripping, light splashing, light spraying of liquid and condensation.

Claims

1. An environmentally resistant lamp system comprising:

a fixture comprising;

a housing providing mechanical support; and

a socket attached to the housing, the socket comprising an electrical contact electrically connected to a power supply;

a lamp comprising;

a base; and

an electrical contact attached to the base,

wherein the lamp is mechanically supported by the socket and the electrical contact of the lamp electrically connects to the electrical contact of the socket; and

a cover comprising a material resistant to dripping liquid, light splashing of liquid, and condensation, the cover having a first opening adapted to receive the base and a second opening adapted to receive the socket,

wherein the cover at least partially surrounds the electrical contact of the socket and the electrical contact of the base.

2. The environmentally resistant lamp system of claim 1, wherein a power supply is mounted to the housing.

3. The environmentally resistant lamp system of claim 1, wherein a power supply is mounted inside the base.

4. The environmentally resistant lamp system of claim 1, wherein the lamp is a germicidal lamp.

5. The environmentally resistant lamp system of claim 1, wherein the liquid is water.

6. The environmentally resistant lamp system of claim 1, wherein the shape and dimensions of the first opening are chosen based on the geometry of the lamp base.

7. The environmentally resistant lamp system of claim 6, wherein

the base is circular in cross-section and has a first diameter

the first opening is circular in cross-section and has a second diameter smaller than the first diameter, and

the cover stretches elastically to receive the base.

8. The environmentally resistant lamp system of claim 1, wherein the shape and dimensions of the second opening are chosen based on the geometry of the socket.

9. The environmentally resistant lamp system of claim 8, wherein the second opening has a generally rectangular cross section defined by first, second, third, and fourth walls.

10. The environmentally resistant lamp system of claim 9, wherein the first opening passes through the first wall.
