Fully analog aquarium for growing tropical plants
Domanský, Ondřej ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
The aim of the thesis will be to clarify issues relating to the cultivation of tropical plants in aquariums. The main aspect of the work is to analyze the ideal environment for the home aquarium and the choice of specific components for plant growth. In the next sections will illustrate also the proposal of such a system and its implementation in ambient conditions.

Design and construction of advanced LED lighting system for aquarium
Novák, Pavel ; Škoda, Jan (referee) ; Pavelka, Tomáš (advisor)
The first part of this thesis is devoted to the presentation of light and the basic quantities describing the light and its properties. These quantities are then used to describe the light sources, which is the thesis engaged in in the following section. The light sources are divided into thermal and luminescent. Then, there are described the basic parameters that are monitored when choosing the light source, such as luminous flux, color rendering index, correlated color temperature, mean lifetime, beam angle. Next, the thesis engages in solar radiation, spectrum of radiation, process and the color temperature of daylight and turns to the requirements for the aquarium lighting. According to the requirements for the aquarium lighting, the lighting design is done and it is sought an ideal solution for the aquarium lighting using LEDs. In conclusion of this thesis, there is designed an effective cooling for the LEDs in order to maintain their lifetime and luminous flux as long as possible. Then, it is designed and realized control of the LEDs by the pulse width modulation, prepared software for controlling the lighting depending on the daytime to meet the demands on the aquarium lighting while monitoring the process of the daylight and to look natural.
