All kinds of gas discharge lamps are composed of a bulb, an electrode and a discharge gas, and the basic structure is similar. A vacuum gas seal is connected between the bulb and the electrode, and the bulb is filled with a discharge gas. The gas discharge lamp cannot be separately connected to the circuit, and must be connected to the circuit with an auxiliary device such as a trigger or a ballast to start and stabilize the work. The start of the discharge lamp usually applies a higher voltage than the supply voltage, sometimes up to several thousand volts or tens of thousands of volts.
The above requirements can be met by using a leakage transformer or by using a starter. Arc discharges generally have a negative volt-ampere characteristic, i.e., the voltage decreases with increasing current. If the discharge lamp is separately connected to the grid, the bulb or circuit components will be destroyed by overcurrent. The discharge lamp and ballast are used in series to stabilize the operation. The ballast can be a resistor, an inductor or a capacitor. Generally, in the case of a DC power supply, a resistance ballast is used, a low-frequency AC power source is used for inductive ballasting, and a high-frequency capacitor is used for ballasting.
The mechanical concealed cistern is a common bathroom fixture that stores flush water and controls flushing. It is usually installed in the wall, and there is only a button on the outside to start the flush. Its design makes the water tank no longer occupy the toilet space, thus providing more free space and beautiful appearance.
Space-saving: The design of the mechanical hidden water tank allows the water tank to be installed inside the wall, saving valuable bathroom space, providing more free space and a beautiful appearance.
Beautiful: The design of the hidden water tank makes it no longer stand in the bathroom like the traditional surface-mounted water tank, thus improving the overall aesthetics of the bathroom.
Water saving: The mechanical hidden water tank can precisely control the water volume when flushing, avoiding excessive consumption of water resources, thereby reducing water usage and saving water bills.
Long service life: Compared with the traditional surface-mounted water tank, the mechanical hidden water tank has a longer service life and lower maintenance costs because it is more concealed and less susceptible to external factors.
More hygienic: The traditional surface-mounted water tank needs to be cleaned frequently, and the scale and sundries hidden inside the water tank are not easy to be polluted by the outside world, so it is more hygienic.
