Abstract

An aquarium lighting device includes an illumination unit and a control unit. The illumination unit has a plurality of light-emitting diodes (LEDs). The LEDs are disposed adjacent to each other and emit different colors of light. The control unit is electrically connected with the LEDs to control the LEDs.

Claims

1. An aquarium lighting device, comprising:

an illumination unit, which has a plurality of light-emitting diodes (LEDs) emitting different colors of light and disposed adjacent to each other; and

a control unit, which is electrically connected with the LEDs for controlling the LEDs.

2. The aquarium lighting device of claim 1, wherein the control unit has a brightness control area, and the brightness control area is a touch-control panel or a knob.

3. The aquarium lighting device of claim 2, wherein the brightness control area has a stripe shape, a circular shape, a saw shape, a spiral shape, a W shape, a Z shape, or an irregular shape.

4. The aquarium lighting device of claim 1, wherein the control unit has a display area showing a brightness of the illumination unit.

5. The aquarium lighting device of claim 1, wherein the control unit has a switch and the switch is a touch-control switch, a button switch, or a knob switch.

6. The aquarium lighting device of claim 1, wherein the control unit has a power input terminal for connecting with an external power supply.

7. The aquarium lighting device of claim 1, wherein the LEDs at least includes a red LED, a greed LED or a blue LED.

8. The aquarium lighting device of claim 1, wherein the illumination unit further comprises a circuit board, and the LEDs are disposed on the circuit board.

9. The aquarium lighting device of claim 1, wherein the control unit has a control circuit for controlling a brightness of the LEDs.

10. The aquarium lighting device of claim 1, wherein the control unit has a control circuit for controlling a color temperature of the LEDs.
