Controlling Light

Operational supplies are frequently used to regulate the intensity of heavy-duty light sources such as xenon or arc lamps. The uniform illumination of a monochronometer is a typical objective. Light sensors typically provide the regulating feedback. These sensors include photomultiplier tubes and photovoltaic or photoresistive semiconductors. Photovoltaic silicon photocells are the most convenient sensors. Their output, however, usually requires some voltage amplification before use as a command signal. A small dc amplifier is generally

High Intensity Discharge Lamps
High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures. HID lamps are often used as UV light sources.
Photomultiplier Tubes
Photomultiplier tubes are good for applications where rapid detection of light or low light detection is necessary.
Lighting Fixtures
Lighting fixtures produce artificial light in industrial areas or workspaces.
Ballasts
Ballasts are electrical devices that condition the line voltage (amplitude, amperage and waveform) to operate fluorescent and HID lamps. Basically they serve two functions: to provide the starting kick, and to limit the current to the proper value for a particular lamp.
Photovoltaic Cells and Panels
Photovoltaic cells or solar cells generate a voltage when radiant energy falls on the boundary between dissimilar substances.  A solar panel, also called a photovoltaic panel, is a group of photovoltaic cells that are enclosed to keep the cells safe and so that the voltage obtained from each cell can be combined.
