Illuminated viewing systems for enclosures

1. An enclosure disposed in an ambient environment, the enclosure comprising:

a cover;

a body detachably coupled to the cover, wherein the body comprises at least one wall that forms a cavity that is enclosed by the cover when the cover is coupled to the body;

at least one electrical device disposed within the cavity; and

at least one illuminated viewing system disposed in an aperture that traverses the cover or in the at least one wall, wherein the at least one illuminated viewing system comprises:

a window disposed in the cover or in the at least one wall, wherein the window is made of a molded polymer and comprises a first layer and a second layer, wherein the first layer is disposed within the aperture, and wherein a portion of the second layer abuts against an inner surface of the cover or the at least one wall; and

at least one light source assembly that directs light within the cavity in which the at least one electrical device is disposed,

wherein the ambient environment is a hazardous environment,

wherein the window and either the cover or the at least one wall form a first flame path therebetween, wherein the first flame path is configured to quench an explosion that originates inside the enclosure, and wherein the first flame path also is configured to allow gases from inside the enclosure to escape and cool as the gases exit the enclosure,

wherein the cover and the body form a second flame path therebetween, wherein the second flame path is configured to quench the explosion that originates inside the enclosure, and wherein the second flame path also is configured to allow the gases from inside the enclosure to escape and cool as the gases exit the enclosure.

2. The enclosure of claim 1 , wherein the at least one light source assembly is disposed within the window.

3. The enclosure of claim 1 , wherein the at least one light source assembly is disposed within the cavity adjacent to the window.

4. The enclosure of claim 1 , wherein the illuminated viewing system further comprises:

a switch coupled to the at least one light source assembly, wherein the at least one light source assembly illuminates when the switch operates.

5. The enclosure of claim 4 , wherein the illuminated viewing system further comprises:

a sensor coupled to the switch, wherein the sensor measures at least one parameter associated with a presence of a user proximate to the window, wherein the sensor operates the switch when the sensor detects the presence of the user.

6. The enclosure of claim 5 , wherein the sensor is disposed on an outer surface of the at least one wall.

7. The enclosure of claim 5 , wherein the sensor is disposed within the window.

8. The enclosure of claim 5 , wherein the sensor is disposed within the cavity.

9. The enclosure of claim 5 , wherein the illuminated viewing system further comprises:

an optical device disposed adjacent to the sensor, wherein the optical device controls a spatial range in the ambient environment from which the sensor measures the at least one parameter.

10. The enclosure of claim 1 , wherein the at least one light source assembly illuminates using power supplied by a power source.

11. The enclosure of claim 10 , wherein the power source comprises an energy storage device.

12. The enclosure of claim 11 , wherein the energy storage device is disposed within the window.

13. The enclosure of claim 1 , wherein the at least one light source assembly comprises a first light source assembly, wherein the first light source assembly directs first light toward a first location within the cavity, wherein at least one device is disposed in the first location.

14. The enclosure of claim 13 , wherein the at least one light source assembly further comprises a second light source assembly, wherein the second light source assembly directs second light toward a second location within the cavity.

15. The enclosure of claim 1 , wherein the illuminated viewing system further comprises:

an optical device disposed adjacent to the window within the cavity, wherein the optical device manipulates a view of a user looking through the window at the at least one location within the cavity.

16. The enclosure of claim 1 , wherein the illuminated viewing system further comprises:

an optical device disposed adjacent to the at least one light source assembly, wherein the optical device manipulates light emitted by the at least one light source assembly toward the at least one location within the cavity.

17. The enclosure of claim 1 , wherein the light directed toward the at least one location within the cavity illuminates a presence of an adverse condition at the at least one location within the cavity, wherein the adverse condition comprises at least one selected from a group consisting of corrosion, a blown fuse, improper mechanical operation of a switch, improper movement of a contactor, mechanical damage, thermal damage, and moisture accumulation.

18. The enclosure of claim 1 , wherein the at least one light source, when illuminated, avoids causing an explosion within the cavity.

19. An enclosure disposed in an ambient environment, the enclosure comprising:

at least one wall that forms a cavity;

at least one electrical device disposed within the cavity; and

at least one illuminated viewing system disposed in the at least one wall, wherein the at least one illuminated viewing system comprises:

a window disposed in the at least one wall, wherein the window is made of a molded polymer; and

a sensor disposed within the molded polymer of the window, wherein the sensor is configured to measure at least one parameter associated with a presence of a user proximate to the window, wherein the sensor operates a switch when the sensor detects the presence of the user, wherein the switch, when operated, provides power to at least one light source to illuminate at least part of the cavity.
