Abstract

A light assembly, comprising: a translucent housing; an inner wall disposed in the translucent housing, the inner wall and the translucent housing defining an inner cavity; a plurality of light emitting diodes electrically coupled to a power source; a switch for electrically connecting and disconnecting the plurality of light emitting diodes to the power source and activating an operating mode including sequential flashing of the plurality of light emitting diodes, the plurality of light emitting diodes and the power source being disposed in the inner cavity; and a removable base configured to be secured to the inner wall, the removable base defining a bottom portion of the housing, the switch being located in the removable base.

Claims

1. A light assembly, comprising:

a translucent housing;

an inner wall disposed in the translucent housing, the inner wall and the translucent housing defining an inner cavity;

a plurality of light emitting diodes electrically coupled to a power source;

a switch for electrically connecting and disconnecting the plurality of light emitting diodes to the power source and activating an operating mode including sequential flashing of the plurality of light emitting diodes, the plurality of light emitting diodes and the power source being disposed in the inner cavity; and

a removable base configured to be secured to the inner wall, the removable base defining a bottom portion of the housing, the switch being located in the removable base.

2. The light assembly as in claim 1, wherein the removable base is constructed out of a plastic material and has a plurality of tabs for removably securing the removable base to the inner wall.

3. The light assembly as in claim 2, wherein the inner wall includes a plurality of slots for correspondingly receiving a portion of the plurality of tabs, the removable base being secured to the housing when the plurality of tabs are received by the plurality of slots.

4. The light assembly as in claim 1, wherein the removable base comprises of a planar surface having a flange portion extending outwardly therefrom, the flange portion having a pair of tabs configured to engage a pair of openings in the inner wall.

5. The light assembly as in claim 4, wherein the flange portion has at least one groove configured to receive an O-ring for providing a seal between the flange portion and the housing and the inner wall.

6. The light assembly as in claim 4, wherein the flange portion has a pair of grooves disposed between the pair of tabs and the planar surface and each groove has an O-ring for providing a seal between the flange portion and a rear portion of the housing and the inner wall.

7. The light assembly as in claim 6, wherein the removable base has a pair of areas disposed on the periphery of the removable base, the pair of areas each defining a pocket between the periphery of the removable base and the housing, the pockets allowing a force to be applied to the removable base to remove the removable base from the housing.

8. The light assembly as in claim 1, wherein the removable base has a pair of areas disposed on the periphery of the removable base, the pair of areas each defining a pocket between the periphery of the removable base and the housing, the pocket allowing a force to be applied to the removable base to remove the removable base from the housing.

9. The light assembly as in claim 1, further comprising a printed circuit board configured to have fixedly mounted therein the plurality of light emitting diodes, the switch, the power source, or a combination thereof, the printed circuit board being received within the inner cavity.

10. The light assembly as in claim 9, wherein the printed circuit board is fixedly attached to a portion of the housing.

11. The light assembly as in claim 1, wherein the housing has a substantially flat vertical wall along one side.

12. The light assembly as in claim 1, wherein at least one of the plurality of light emitting diodes is oriented approximately 12 degrees from a vertical axis extending through the housing.

13. The light assembly as in claim 1, wherein the housing has a substantially parabolic shape.

14. The light assembly as in claim 1, wherein the power source is a battery.

15. A method of removably securing a base portion to a translucent housing of a light assembly, the method comprising:

providing a base portion with a planar surface and a flange portion depending away from the planar surface, the flange portion having at least one tab and at least one O-ring configured to removably engage a portion of the housing and an inner wall of the housing; and

securing the base portion to the housing by positioning the at least one O-ring between the portion of the housing and the inner wall and by engaging a feature of the at least one tab with an opening in the inner wall.

16. The method as in claim 15, wherein a peripheral portion of the base portion is configured to have at least one area to define a pocket between the peripheral portion of the base portion and the housing, the pocket being configured to allow a force to be applied to the base portion to remove the base portion from the housing.
