Abstract

Various embodiments of the present invention provide a lighting system and apparatus that may be utilized with aquariums. The features and functionality of the lighting system and apparatus provide easy access to the opening of an aquarium for various purposes, such as cleaning and maintenance. In addition, the features and functionality of some embodiments provide a lighting system that does not require ballasts, light sockets, or a multitude of wiring, and includes a modular design. Further, for some embodiments, features of the present invention allow the lighting apparatus to illuminate the aquarium, while simultaneously limiting the evaporation of water from the aquarium.

Claims

1. A modular aquarium light fixture, comprising:

a removable light module comprising;

a printed circuit board having an anterior surface, a posterior surface, and a board contour,

a light element disposed on the anterior surface, and

a plurality of conductive contacts disposed on the anterior surface; and

an open cavity configured to receive and selectively retain the removable light module, the open cavity comprising;

a cavity wall having a height that corresponds to the board contour,

a cavity rim having a plurality of protruding elements that each have a posterior side facing perpendicular to the direction of protrusion and facing an interior of the cavity, the cavity rim being configured to receive the removable light module, and

a conductive element disposed on the posterior side of each protruding element.

2. The modular aquarium light fixture of claim 1, wherein the board contour comprises a plurality of grooves that correspond to the protruding elements of the cavity rim, thereby allowing the removable light module to be inserted into the open cavity, and wherein the height of the cavity wall is such that once the removable light module is placed within the open cavity and rotated within the open cavity to a secure position, at least one of the plurality of conductive contacts comes in contact with the conductive element of at least one of the plurality of protruding elements.

3. The modular aquarium light fixture of claim 1, wherein a surface feature is disposed on the anterior surface of the printed circuit board, the surface feature configured to assist in retaining the removable light module in the open cavity once the removable light module is placed within the open cavity and rotated within the open cavity to the secure position.

4. The modular aquarium light fixture of claim 1, wherein the board contour is substantially circular.

5. An aquarium lighting system, comprising:

a modular light fixture, comprising;

a heat sink;

a removable light module comprising;

a printed circuit board having an anterior surface, a posterior surface, and a board contour,

a light element disposed on the anterior surface, and

a plurality of conductive contacts disposed on the anterior surface; and

an open cavity configured to receive and selectively retain the removable light module, the open cavity comprising;

a cavity wall having a height that corresponds to a profile of the printed circuit board, and having a shape configured to receive the board contour,

a cavity rim having a plurality protruding elements that each have a posterior side facing perpendicular to the direction of protrusion and facing an interior of the cavity, the cavity rim being configured an interior of the cavity, and configured to receive the removable light module, and

a conductive element disposed on the posterior side of each protruding element;

wherein a thermal compound is disposed between the removable light module and the heat sink, wherein the board contour comprises a plurality of grooves that correspond to the protruding elements of the cavity rim, thereby allowing the removable light module to be inserted into the open cavity, and wherein the height of the cavity wall is such that once the removable light module is placed within the open cavity and rotated within the open cavity to a secure position at least one of the plurality of conductive contacts comes in contact with the conductive element of at least one of the plurality of protruding elements.

6. The aquarium lighting system of claim 5, wherein the modular light fixture further comprises a thermal switch configured to shut power off to the modular light fixture when the modular light fixture is operating above a maximum operating temperature.

7. The aquarium lighting system of claim 6, wherein the modular light fixture further comprises an internal circuit configured to shut power off to the modular light fixture when the internal circuit detects a ground fault.

8. The aquarium lighting system of claim 5, further comprising a clear acrylic cover that protects the light element from water exposure, wherein the clear acrylic cover comprises an optical lens placed at a location on the clear acrylic cover above the light element.

9. The aquarium lighting system of claim 5, wherein an internal reflector is mounted on the light element for providing an angular light dispersion.

10. The aquarium lighting system of claim 5, further comprising a mounting mechanism configured to mount the modular light fixture onto an aquarium wall.

11. The aquarium lighting system of claim 10, wherein the mounting mechanism comprises:

a fixture chassis configured to mount to the aquarium wall; and

a screw to mount the modular light fixture to the fixture chassis.

12. The aquarium lighting system of claim 10, wherein the mounting mechanism comprises:

a fixture chassis configured to mount to the aquarium wall;

a resting bracket configured to rest on the fixture chassis; and

a screw to mount the resting bracket to the modular light fixture.

13. The aquarium lighting system of claim 5, wherein the light element includes a light emitting diode, an organic light emitting diode, a xenon bulb, a halogen bulb, or an electroluminescent light source.

14. The aquarium lighting system of claim 5, wherein the modular light fixture is configured to be connected as a link in a daisy chain of modular light fixtures.

15. The aquarium lighting system of claim 5, further comprising a power supply unit that is electrically coupled to the modular light fixture, wherein the power supply unit supplies power to the modular light fixture;

and a controller connected between the power supply unit and the modular light fixture, wherein the controller controls a parameter of the light element in the modular light fixture.

16. The aquarium lighting system of claim 15, wherein the parameter includes one or more selected from the group consisting of a color pattern, lighting pattern, light intensity, and light timing.
