DETAILED DESCRIPTION
The present invention relates generally to control systems and methods for aquarium lighting. More particularly, the present invention relates to upgradeable control systems and methods for LED-based aquarium lighting for plants and/or animal habitat, marine life, etc.
FIGS. 1-3 illustrate an LED-based aquarium lighting system 10 (see FIG. 3) which includes an LED source 12, a marine habitat 14, and a control system 16. The control system 16 comprises a motherboard 18, a control panel 20, and a control module 22 (see FIGS. 1 and 2). As shown in FIG. 2, the control module 22 can be replaced with a new control module 24, or in another embodiment, at least one additional control module 24 can be added and coupled to the motherboard 18. The control module 22 and/or the at least one additional control module 24 provide new or different operational modes and features to the system 16.
As shown in FIGS. 2-3, the motherboard 18 may include a user display (LCD) and a plurality of connectors to link the control modules 22, 24 and the control panel 20. The motherboard 18 provides an interface between control modules 22, 24 and the LED source 12 which may include a plurality of LED lights. Accordingly, the motherboard 18 is the heart of the control system 16 and serves as a central connection point to all other system components.
The control panel 20 is a separate unit that plugs into the motherboard 18. The control panel 20, along with the user display on the motherboard 18, comprises a user interface for the aquarium lighting system 10. The control panel 20 contains a number of buttons or button-type functions that are used to change settings, modes, and features of the lighting system 10, and feedback to the user is provided by the user display, for example, a motherboard-mounted display. The motherboard 18 may be installed into a lighting fixture of the LED source 12 such that the display is visible to the user.
The control module 22, 24 is a separate circuit board that plugs into the motherboard 18 via an edge connector 26. The control software and hardware (i.e. the system microprocessor) are contained on the control module 22. Operations of all the lighting system 10 are defined by the software which is installed on the control module 22, 24. The control module 22, 24 is designed to be easily removable by the end user. Accordingly, to upgrade the lighting system 10, the user removes the existing control module 22 and installs a new control module 24 with different software in its place.
In FIG. 2, the control system 16 allows several different types of upgrades, some of which are shown, but not limited to those shown in FIG. 2. The most basic upgrade may be a software (feature set) upgrade. For example, if a user desires to upgrade to the newer version of the control software (with added features, such as user controlled colors, moonlight cycles, etc), the user may purchase and install a new control module 24 with the appropriate software installed. In this case, the control system configuration, e.g. the physical hardware, is the same, i.e. only the software is changed. One of the advantages of the present invention is that this design also allows much more substantial upgrades to be installed. For example, the control module 16 may be replaced with a new control module 24 that contains a wireless transceiver in addition to the microprocessor. Depending on the hardware on the new module 24, the user may then control the lighting system 10 via a handheld remote control, home computer, or even remotely via the Internet over the user's home wireless network. Since the interface between the control module 22, 24 and the motherboard 18 does not change, any number of different communications protocols may be added to future control modules, including but not limited to, RS232, USB, WiFi, Bluetooth, etc.
One advantage of the present invention is that the system is designed so that a user may easily perform the upgrade, without requiring an entire lighting system to be returned to a manufacturer or point of sale.
Further, it is appreciated that other types of control modules can be designed to upgrade existing control modules and installed in a control system provided in the present invention, rather than requiring an end user to buy a completely new lighting system.
These and other features of the present invention will become apparent to those skilled in the art. As it will be realized, the present invention is capable of modifications in various obvious aspects, all without departing from the spirit and scope of the present invention.
