  2. Intelligent street lighting - Wikipedia

    en.wikipedia.org/wiki/Intelligent_street_lighting

    Intelligent street lighting. Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars in a smart city. [1] Also called adaptive street lighting, it brightens when sensing activity and dims while not. This is different from traditional stationary illumination, and that which dims on a ...

  3. Photoresistor - Wikipedia

    en.wikipedia.org/wiki/Photoresistor

    Photoresistor. A photoresistor (also known as a light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity. A photoresistor can be used in light-sensitive detector circuits and ...

  4. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    The benefit of architectural lighting control systems in the theater is the ability for theater staff to turn worklights and house lights on and off without having to use a lighting control console. Alternately, the light designer can control these same lights with light cues from the lighting control console so that, for instance, the ...

    en.wikipedia.org/wiki/Tone_mapping

    Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.

  6. Smart traffic light - Wikipedia

    en.wikipedia.org/wiki/Smart_traffic_light

    Smart traffic light. Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. [1] They can form part of a bigger intelligent transport system.

  7. Intelligent lighting - Wikipedia

    en.wikipedia.org/wiki/Intelligent_lighting

    A Martin MAC 550 intelligent light. Several intelligent lights in use at a concert. Note the white beams they produce. Intelligent lighting refers to lighting that has automated or mechanical abilities beyond those of conventional, stationary illumination. Although the most advanced intelligent lights can produce extraordinarily complex effects ...

  8. Variable-gain amplifier - Wikipedia

    en.wikipedia.org/wiki/Variable-gain_amplifier

    A variable-gain (VGA) or voltage-controlled amplifier (VCA) is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude modulation. A crude example is a typical inverting op-amp configuration with a light ...

  9. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection). Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control, home control, energy efficiency ...
