DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to Fig. 1a, there is shown a schematic representation of an aquarium illumination system 100 according to the present invention. The illumination system includes an illumination device 110 includes an enclosed housing 115 in which there is disposed a light emission assembly 112 therein. The light emission assembly 112 includes LED light emission devices 114a, 114b as well as electronic circuitry 116 which controls the light emission devices 114a, 114b. The enclosed housing 115 prevents the ingress of water and humidity from the adjacent body of water 132 within an aquarium 130. The illumination device 110 further includes an air inlet port 111 and an air outlet port 113, which are in communication with inlet conduit 130 and exit conduit 140 respectively.

The illumination device 110 is positioned above the aquarium or the like 130 which contains a body of water 132. The inlet conduit 130 is connected to an air pump 120 so as to provide a flow of air into the enclosed housing 115 which exits the housing 115 via the air outlet port 113 and outlet conduit 140.

The exit air 160 may be used for aerating the body of water 132 by way of an aquarium air stone, or alternatively for connection to an air operated filtration system or the like, or other such applications typically implemented in conjunction with an aquarium. A non-return valve 150 may be provided so as to prevent water from entering the enclosed housing 115 via the outlet conduit 140. Alternatively, the nonreturn valve 150 may be implemented integrally with the illumination device in other or alternate embodiments. Power is provided to the light emission assembly 112 by way of power line

118, which may be either mains power operable, or alternatively by way of a reduced voltage if required, as will be appreciated by those skilled in the art.

Aquarium illumination devices, due to the proximity of such devices to a water environment, are typically exposed to the problem of corrosion due to humidity to electrical circuitry by being located adjacent a body of water of the aquarium. In particular, LED or high power LED devices, which generally require electronics for control thereof, are potentially exposed to humidity which may impact upon longevity of the devices and associated circuitry, as well as cause occupational health and safety risks. In order to prevent ingress of water and protect the light emission assembly including illumination devices such as LEDs and associated electronics, an enclosed housing 115 in accordance with the present invention has been provided which prevents the ingress of water and humidity into the illumination device 110. As will be understood and appreciated by those skilled in the art, in order to satisfactorily illuminate a body of water such as that in an aquarium or the like, light emission devices such as LEDs must be able to provide sufficient lighting power to adequately eliminate the body of water. In an example of a typical aquarium illumination device, there may exist two or more three Watt high power LEDs, which when in an open environment, may generate temperatures of approximately 90°C. However, when such LEDs are within a sealed environment without any cooling or the like, the ambient temperature exceeds 100°C, and the LEDs begin to become faint, lose power, and ultimately fail prematurely due to extensive heat. However, in the present invention, the air flow through the enclosed housing 115 provides "air cooling" by air introduced into the enclosed housing 115, which circulates about the light emission assembly 112 and light emission units 114a and 114b so as to provide suitable cooling of the circuitry and light emission devices, and exit by way of the exit port.

Those skilled in the art will appreciate that LEDs of higher wattage and a greater number of such LEDs may be utilised, without departing from the scope of the invention.

Advantageously, the present invention utilizes an aquarium "air pump" in order to provide air flow and cooling of the electronic and lighting components within the enclosed housing. As will be appreciated and understood by those skilled in the art, aquariums require an air pump for both aeration of water, as well as in conjunction with air-operable filtration systems for filtration of water in an aquarium. In some aquariums, air pumps may be integrally provided within a housing below or cover assembly above the aquarium. As such, the present invention utilizes an existing aquarium "air pump" in order to provide air cooling to an illumination device for which ingress of water and humidity is prevented, so as to efficiently cool the componentry and thus increase longevity and efficiency of the illumination device.

Furthermore and advantageously, air exiting the illumination device may be utilized directly for aeration and/or filtration of the water in an aquarium. The extent of the increase in temperature of the exit air 160 from the enclosed housing 160 when utilised for aeration or filtering provides insignificant alteration of the aquarium water temperature.

Referring to Fig. 1 b, a similar schematic representation of an aquarium illumination system 100a according to the present invention is shown as to that as shown in Fig. 1 a whereby the illumination device 110 and associated components are the same. However, in the schematic representation of the embodiment of Fig. 1 b, the power line 118 provides power from the same power supply that powers the air pump 120. In this embodiment, the power supply may also include a voltage adaptor, for example a voltage step-down adaptor from 110V/240V down to 12V for powering both the air pump 120 and the illumination device 110a which includes in this embodiment high power HPLEDs. Those skilled in the art will appreciate that systems 100 of Fig. 1 a may be used for larger aquariums, whilst systems 100a of Fig. 1 b may be more applicable to smaller aquariums in some cases.

Referring to Fig. 2, there is shown an embodiment of an aquarium illumination system 200 according to the present invention. Similarly as described above in reference to the embodiments of Fig.1a and 1 b, the illumination system 200 in the present embodiment includes an illumination device 210 including an enclosed housing 215 and light emission assembly 212.

In the present invention, the power line 218 of the illumination system 200 gains power from the power supplied to the air pump 220, rather than by way of a separate power supply. In embodiments of the present invention, as will be appreciated by those skilled in the art, the power line 218 and the inlet conduit 230 may be provided as a single integral line from the air pump 220 to the illumination device 210 such that the aquarium illumination system 200 is provided as an integral unit.

Those skilled in the art will appreciate that the operable advantages of having a unitary system which provides both air to an aquarium for filtration and aeration of the water, as well as provides illumination to the body of water 232 within the aquarium 230.

Furthermore, those skilled in the art will appreciate that an aesthetically pleasing illumination and filtration system without numerous separate conduits and power leaks can be implemented without unsightly cabling and conduits, as well as providing ease of installation of such power and air lines due to a single assembly 212 being utilized.

Still further, the present embodiment provides the advantage of a single power outlet being required from the main supply, again reducing the amount of unsightly cabling and the necessity of multiple AC adaptors or power boards or the like.

Referring to Fig. 3, there is shown a further embodiment of an aquarium illumination system 300 according to the present invention. In the embodiment of Fig. 3, although the exit air 360 from the outlet port 313 and outlet conduit 340, although preferably used within the aquarium 330 for aeration of the body of water 332, the air may be discharged to atmosphere, or alternatively utilized for other applications, other than aeration of the body of water 332.

In the present embodiment, as will be appreciated by those skilled in the art, air from the air pump may be utilized directly for aeration of the water by way of an air filter 317 or the like, for other applications. Again, the system 300 may be integrally formed similar as discussed in relation to the embodiment of Fig. 2 above, and thus provide similar such advantages and benefits as will be appreciated by those skilled in the art. Referring to Fig. 4, there is shown yet a further embodiment of an aquarium illumination system 400 according to the present invention. Similarly as described in reference to embodiments above, the system comprises an illumination device 410 which includes an enclosed housing 415 and a light emission assembly 412. In the present embodiment, a heater component 470 is implemented within the system for heating of the body of water 432 of the aquarium 430, in applications in which such heating is required.

Again, similarly as described in reference to the above embodiments, an integrally formed system having a single feed line from the illumination device 410 to the air pump 420 provides for an aesthetically pleasing configuration, ease of installation, as well as obviates the necessity for separate and unsightly electrical cabling and conduits. This system also obviates the necessity for more than one AC power socket in order to power the system 400.

Referring to Figs. 5a, 5b, 5c and 5d, there are shown various schematic embodiments of an aquarium illumination device 500a, 500b, 500c and 500d, according to the present invention. Referring to Fig. 5a, in this embodiment the enclosed housing 510a includes integrally formed ends which are joined to the inlet and outlet conduits 531a, 532a. As will be understood and appreciated by those skilled in the art, flow of air provides convection cooling of the electronic components and LEDs 522a within the enclosed housing 510a.

In another embodiment of an illumination device 500b as shown in Fig. 5b, the enclosed housing 510b is provided in a tubular form, with end caps 533b inserted therein so as to prevent ingress of water and humidity within the illumination device.

Referring to Fig. 5c, the inlet conduit 531 c extends into and within the enclosed housing 510c and includes a plurality of apertures 535c which allows air to be directed onto the electrical componentry of the light emission assembly 524. Air then exists the enclosed housing by way of outlet conduit 532c. Those skilled in the art will appreciate and understand that appropriate positioning and sizing of the apertures 535c provides suitable air cooling to the electrical componentry and that air may be directed towards specific components which require greater dissipation and cooling within the enclosed housing 510c.

Referring to Fig. 5d, a similar embodiment as that as shown in Fig. 5b is depicted, however in the present embodiment, the power line 526d of the illumination device 500d is provided adjacent with the air inlet conduit 531 d for ease and convenience of installation and deployment of the illumination device 500d adjacent an aquarium.

Referring to Fig. 5e, a similar embodiment as that as shown in Fig. 5a is depicted, however the inlet conduit 531e and outlet conduit 532e are located at the same end of the illumination device 500e. This allows power, air supply and air outlet to all be fed by way of a single conduit. Referring to Fig. 5f, a embodiment is shown which includes features from both Fig. 5e and Fig. 5c, in that the inlet conduit 531f and outlet conduit 532f are located at the same end of the illumination device 500f, and the inlet conduit 531f extends into and within the enclosed housing 51 Of and includes a plurality of apertures 535f which allows air to be directed onto the electrical componentry of the light emission assembly.

Referring to Fig. 6, there is shown an exemplary embodiment of an aquarium illumination device 610 according to the present invention. In the present embodiment, the enclosed housing 615 is provided as a glass tube which is enclosed at each end by way of rubberised stopper members 621 and 622 located at the inlet and outlet ends of the device respectively.

The light emission assembly 612 is suspended within the glass tube 610 by way of the rubber stopper members 621 , 622 such that the LED light emission devices 614a and 614b are suitably distanced from the internal surface of the glass tube so as to allow air flow therebetween.

A non-return valve 623 is provided within stopper member 622 so as to prevent ingress of water or moisture from outlet conduit 640 into the enclosed housing from an aquarium or the like which the illumination device 615 is utilized to illuminate. In the present embodiment, power line 618 is located at the inlet end of the enclosed housing 610 for convenience so as to optionally allow the inlet conduit 630 to be formed integrally with the power line 615.

The present invention, by providing an illumination device 610 which is sealed from ingress of water and humidity from an aquarium or body of water for which the illumination device is being utilized to illuminate, allows for the device 610 to be readily placed adjacent the body of water for lighting thereof. Furthermore, by utilizing air flow in order to cool componentry associated with LED illumination devices 614a, 614b within the illumination device 610, thus obviating the requirements for heat sinks and fans which are utilized for cooling of such LED lighting devices according to the prior art. Referring to Fig. 7a and Fig, 7b, there is shown two variations of another embodiment of an illumination system 700 according to the present invention. In this embodiment, an air pump 780 is included within the enclosed housing 715. In the present embodiment, the air pump 780 is positioned towards the inlet port 711 end of the enclosed housing 715. The air pump 780 is in fluid communication with the inlet port 711 , and draws air from external of the system 700 which in turn is pumped through the enclosed housing 715 and exits via the outlet port 713 such that the light emission assembly 712 is maintained at an operable temperature.

In the present embodiment, the air pump 780 is in electrical communication with the light emission assembly 712 such that power for the air pump is derived from the light emission assembly 712. As such, a single power supply may be utilized to provide electrical power to both the air pump 780 and the light emission assembly 712.

Alternatively, as will be appreciated by those skilled in the art, the electrical power supply could supply power directly to the air pump, and the light emission assembly 712 derive power from the air pump.

Further, a single power supply could provide power to the system, and independently provide power to both the air pump 780 and the light emission assembly 712. Still further as will be appreciated by those skilled in the art, separate power supplies could provide power to the air pump 780 and the light emission assembly 712, without departing from the scope of the invention.

Those skilled in the art will appreciate that the unitary construct as in the present embodiment obviates the necessity for an external air supply, as well as obviates the necessity for a conduit to provide air supply to the system 700.

Optionally, the exhaust air may be vented to atmosphere as shown in Fig. 7a. Alternatively, exhaust air may be vented under water by way of an air stone, filtration unit or the like as shown in Fig 7b, depending upon the application and requirements of the system and the implementation thereof. Referring to Fig. 8, there is shown yet another embodiment of a system 800 according to the present invention. In the present embodiment, an air pump 880 is provided within the enclosed housing 815 adjacent the exit port 813 end of the enclosed housing 815.

In the present embodiment, the air pump 880 is in fluid communication with the outlet port 813, which enables the air pump 880 to draw air from the enclosed housing which has been heated by the light emission devices 814a, 814b, and exit such air from the enclosed housing via the outlet port 813, as well as draw cool air from external of the enclosed housing 815 through the inlet port 811 in order to maintain the light emission assembly 812 at an operable temperature. Optionally, the exhaust air may be vented to atmosphere as shown in Fig. 8a.

Alternatively, exhaust air may be vented under water by way of an air stone, filtration unit or the like as shown in Fig 8b, depending upon the application and requirements of the system and the implementation thereof. Those skilled in the art will appreciate that the manner in which the power is supplied to the air pump 880 as described above in reference to the air pump 780 of the embodiment as described with reference to Fig. 7 is equally applicable to the present embodiment and as such, the present embodiment also provides the same advantages as provided by that and as described above in reference to Fig. 7.

As such, the present invention provides a device which may be more readily and reliably utilized for placement thereof adjacent water and illumination thereof, without the necessity of increasing the length, width or breadth or overall size of a lighting assembly for an aquarium.

Furthermore, air flow from an aquarium pump has been found by the inventor of the present invention to suitably cool an illumination device according to the present invention having two 3 Watt high power LEDs to a temperature of about 80°C, which is sufficiently low so as not to adversely impact upon the performance of such LEDs or impact upon longevity power or the like.

Those skilled in the art will appreciate that more LED light sources or LED light sources of higher wattage may be implemented, without departing from the scope of the invention. Those skilled in the art will also appreciate that other high power LED light source implementations may be implemented within the invention and within the enclosed housing, such as electronic drivers, touch control, timers or the like, so as to provide suitable control for requisite light conditions or requirements depending upon the application of the illumination device.

Those skilled in the art shall further appreciate that in view of aesthetically pleasing aquarium systems, such as those implemented within domestic

environments, it is necessary to illuminate the water of an aquarium without unsightly or noisy cooling devices for cooling the lighting system, as provided by the present invention.

Furthermore, obviating the necessity for unsightly multiple conduits and power leaks provides a more aesthetically pleasing and easy to install illumination system than those as provided by the prior art. Still further, utilizing existing air pump units which are present in aquarium installations allows for the provision of the illumination device according to the present invention which is suitably cooled without the necessity of any further cooling equipment or the like, other than the air pump which is present in aquarium environment in any event.

Those skilled in the art shall appreciate that depending upon the power and design requirements, a suitable air flow from the air pump is required so as to maintain the light emission devices, typically LEDs or HP LEDs, within their typical temperature operating parameters. Again, this is dependent upon the number of light emission units as well as the application of the illumination device, as will be appreciated by those skilled in the art.

While the present invention has been explained by reference to the examples or preferred embodiments described above, it will be appreciated that those are examples to assist understanding of the present invention and are not meant to be restrictive.
