  2. Photoresistor - Wikipedia

    en.wikipedia.org/wiki/Photoresistor

    Three photoresistors with scale in mm Large CdS photocell from a street light. A photoresistor is less light-sensitive than a photodiode or a phototransistor. The latter two components are true semiconductor devices, while a photoresistor is a passive component that does not have a PN-junction. The photoresistivity of any photoresistor may vary ...

    en.wikipedia.org/wiki/Resistive_opto-isolator

    Opto-isolator VTL2C1 with LED input and photoresistor output. Resistive opto-isolator (RO), also called photoresistive opto-isolator, vactrol (after a genericized trademark introduced by Vactec, Inc. in the 1960s), analog opto-isolator [notes 1] or lamp-coupled photocell, [1] is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically ...

    en.wikipedia.org/wiki/Device_for_Connection_of...

    Device for Connection of Luminaires (DCL) is a European standard for ceiling light fixtures introduced in 2005 and refined in 2009. It uses 6 ampere. DCL must carry the CE marking as per the Low Voltage Directive. DCL is only allowed to be installed with ground. Example of DCL socket.

  5. Phototube - Wikipedia

    en.wikipedia.org/wiki/Phototube

    Two different types of phototubes. A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a 'photoemissive cell' to distinguish it from photovoltaic or photoconductive cells.

  6. Photometry (optics) - Wikipedia

    en.wikipedia.org/wiki/Photometry_(optics)

    A photocell rotates about the lamp in three axes, measuring the output of the lamp from all sides. Lamps and lighting fixtures are tested using goniophotometers and rotating mirror photometers, which keep the photocell stationary at a sufficient distance that the luminaire can be considered a point source. Rotating mirror photometers use a ...

  7. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    What made this protocol more attractive, and able to compete with the established analog option, was the simple wiring. There are two types of lighting control systems which are: Analog lighting control; Digital lighting control; Examples for analog lighting control systems are: 0-10V based system.

  8. Hybrid solar lighting - Wikipedia

    en.wikipedia.org/wiki/Hybrid_solar_lighting

    Hybrid solar lighting (HSL) or hybrid lighting systems combine the use of solar with artificial light for interior illumination by channelling sunlight through fiber optic cable bundles to provide solar light into rooms without windows or skylights, and by supplementing this natural light with artificial light—typically LED—as required.

  9. Light fixture - Wikipedia

    en.wikipedia.org/wiki/Light_fixture

    A light fixture (US English), light fitting (UK English), or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. [1] All light fixtures have a fixture body and one or more lamps.
