Electric light sources typically exhibit temporal variations in luminous flux output, commonly referred to as “flicker.” Flicker, or temporal modulation, is known to influence the growth, health and behavior patterns of humans, and is also linked to growth, health and behavior patterns throughout the growth cycle of plants and animals. Control of peak radiant flux emitted by a light source to temporally modulate a light source will allow for the control of plants and animals for sustainable farming including but not limited to horticultural, agricultural, or aquacultural endeavors.

The invention relates to an underwater switch unit for voltage supply of electrical devices (11), particularly in the low voltage range, having a housing (19) which is preferably designed to be water-tight, in which an electronics unit (2) is arranged, by means of which an input voltage, which can be connected via an input connection of the underwater switch unit (14), can be distributed in parallel to a plurality of output connections (16) of the underwater switch unit (14), wherein at least two of the output connections (16) can be supplied with voltage separate from each other via at least one switch element (7, 8) of the underwater switch unit (14), and wherein the uncontrolled underwater switch unit (14) comprises a data bus connection having a related data bus interface, via which an informational signal concerning the voltage connection of an output connection (16) can be detected.

The invention discloses a circular aquarium lamp that comprises of a lamp body and a lamp bracket, wherein the bracket is connected with the body through a universal ball head. The body includes an upper and lower shell, an LED lamp panel and a heat-dissipating aluminum. The upper and lower shells are connected by a screw. The LED lamp panel and heat-dissipating aluminum are installed separately in a cavity that is formed between the upper and lower shell. The LED lamp panel is located under the heat-dissipating aluminum with a fan on top. A first rubber ring is set in between the LED lamp panel and a water-proof cover, whereas a second rubber ring is set in between the cover and a glass sheet. A control board is contained inside a circuit board shell which is installed in the lower shell.

The radiator of this circular aquarium lamp has adopted a strong convective heat-dissipating design, thereby increasing greatly the cooling effects. Its fan will be turned on automatically when the temperature is relatively high, improving further the heat-dissipating performance. The lamp is of strong practicability and easy to popularize and use.

An actuated aquarium decoration system is placed within an aquarium in order to provide an aesthetic appeal to onlookers of the aquarium. The actuated aquarium decoration system includes an aquarium decoration, an actuation mechanism, and a control system. The aquarium decoration is an object placed into the aquarium to provides a theme or habitat within the aquarium. The actuation mechanism engages an accenting feature of the aquarium decoration in order to provide motion or character to the aquarium decoration. The control system the duration, intensity, and frequency of the accenting feature through managing the output of the actuation mechanism.

This invention is related to an aquaculture heating device. A heating unit is hung on a support rod, so that the support rod can be horizontally placed above an aquaculture and two ends of the support rod can be fixedly positioned on two sides of the aquaculture to let the heating unit hung on the support rod to be dropped and immersed in the water of the aquaculture when winter, especially cold stream, comes. When electricity is provided to conductive yarns of a heating layer of the heating unit, heating filaments of the conductive yarns will generate heat to be transferred to the water and gradually diffused throughout the aqua culture through the waterproof fabric layer. Thus, the water temperature is raised to effectively help the aquatic organisms to resist the cold winter and not to be frozen to death caused by the very low water temperature.
