  2. Automotive lighting - Wikipedia

    en.wikipedia.org/wiki/Automotive_lighting

    The extended lighting cycle usually ends when the vehicle's ignition has begun, or a gradual reduction in light emitted after a couple of minutes if the car is not started, called "theater" lighting. Interior lighting has been added on some vehicles at the bottom edge of the dashboard, illuminating the floor for front passengers, or underneath ...

    A rear reflector on a bicycle Reflecting device on horse. A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles. A safety reflector is similar to reflective stripes that can be found on safety vests and clothing worn by road workers and rescue workers. They are sometimes erroneously ...

    en.wikipedia.org/wiki/Parabolic_aluminized_reflector

    Between 1940 and 1956, all U.S. cars had to have two 7-inch (178 mm) round headlamps with dual filaments, so each lamp provided both a high and a low beam light distribution. In 1957, a system of four sealed-beam headlamps—two per side, of 5 + 3 / 4 inches (146 mm) diameter, was allowed in some U.S. states. The following year in 1958, all ...

    Intelligent Light System on A-Class. Intelligent Light System is a headlamp beam control system introduced in 2006 on the Mercedes-Benz E-Class (W211) [154] which offers five different bi-xenon light functions, [155] each of which is suited to typical driving or weather conditions: Country mode; Motorway mode; Enhanced fog lamps; Active light ...

  6. Sodium-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Sodium-vapor_lamp

    When the lamp is first started, it emits a dim red/pink light to warm the sodium metal; within a few minutes as the sodium metal vaporizes, the emission becomes the common bright yellow. These lamps produce a virtually monochromatic light averaging a 589.3 nm wavelength (actually two dominant spectral lines very close together at 589.0 and 589. ...

    The surface of this type of vibrating coating line is distributed and scattered with raised bumps. Some bumps are coated with high-refractive-index glass beads.When a speeding vehicle runs over the raised road lines, it produces a strong warning vibration to remind the car driver of deviation from the lane.

    Diagram of a high-pressure sodium lamp A high-pressure sodium lamp, Philips Master SDW-T 100W. Various types of chemistry are used in the arc tubes of HID lamps, depending on the desired characteristics of light intensity, correlated color temperature, color rendering index (CRI), energy efficiency, and lifespan.

  9. Beam projector - Wikipedia

    en.wikipedia.org/wiki/Beam_projector

    A beam projector is a lenseless stage lighting instrument with very little beam spread. [1] It uses two reflectors. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector. The parabolic reflector organizes the light into nearly parallel beams, and the spherical reflector is placed in front of the ...
