  • laser lighting display

    a laser lighting display or laser light show involves the use of laser light to entertain an audience. a laser light show may consist only of projected laser beams set to music, or may accompany another form of entertainment, typically musical performances.. laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the .

  • full-spectrum light

    full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching earth changes with time of day, latitude, and atmospheric conditions.

  • winter light festival

    each of these bulbs is the representation of a tiny flower, and all together, they d a wonderful path across the entire park. in recent times, a new light tunnel has been added: the kawazu sakura light tunnel, 100 meters long with around 700, 000 pink led lights.

  • metal-halide lamp

    a metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides compounds of metals with bromine or iodine .it is a type of high-intensity discharge hid gas discharge lamp. developed in the 1960s, they are similar to mercury vapor lamps, but contain additional metal halide compounds in the quartz arc tube .

  • li-fi

    in technical terms, li-fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. in its present state, only led lamps can be used for the transmission of visible light.

  • street light

    new street lighting technologies, such as led or induction lights, emit a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights. however, there have been no formal specifications written around photopic/scotopic adjustments for different types of light sources, causing many municipalities and street departments to hold back on implementation of these new technologies until the standards .

  • high-intensity discharge lamp

    high-intensity discharge lamps hid lamps are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. this tube is filled with noble gas and often also contains suitable metal or metal salts.

  • germicidal lamp

    glow of a germicidal lamp excited by a high voltage probe. close-up of the electrodes and the safety warning. a germicidal lamp is a special type of lamp that produces ultraviolet c uvc light. this short-wave ultraviolet light disrupts dna base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoa.

  • queen creek tunnel

    in october 2016, the tunnel lighting system was upgraded to light-emitting diode led technology; it was the first tunnel in arizona to get leds. the lighting system adjusts the lighting level based upon ambient light and weather conditions outside with an adaptive control system. the system offers improved visibility, reduced energy .

  • cree inc.

    in 2011 cree acquired ruud lighting, a national firm experienced in the use of led for outdoor lighting. this expanded cree sales channels and led to a new generation of lighting-class led components. in 2012 cree announced the xlamp xt-e, which was claimed to deliver twice as much light for the same price as older leds.

  • light tube

    light tube with reflective material a light . compared to artificial lights, light tubes have the advantage of providing natural light and of saving energy. the transmitted light varies over the day; should this not be desired, light tubes can be combined with artificial light in a hybrid set-up.

  • light tube

    light tube with reflective material a light . compared to artificial lights, light tubes have the advantage of providing natural light and of saving energy. the transmitted light varies over the day; should this not be desired, light tubes can be combined with artificial light in a hybrid set-up. some artificial light sources are marketed which have a spectrum similar to that of sunlight, at .

  • uk railway signalling

    the railway signalling system used across the majority of the united kingdom rail network uses lineside signals to control the movement and speed of trains.. the current system mostly uses two, three, and four aspect colour-light signals using track circuit block signalling. it is a development of the original absolute block signalling that is still being used on many secondary lines.

  • germicidal lamp

    a germicidal lamp is a special type of lamp which produces ultraviolet uvc light. this short-wave ultraviolet light disrupts dna base pairing causing formation of pyrimidine dimers and leads to the inactivation of bacteria, viruses, and protozoa. it can also be used to produce ozone for water disinfection.

  • lumen unit

    explanation. if a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen 1 cd ·1 sr = 1 lm . alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4π lumens.

  • baker–barry tunnel

    workers sealed cracks in the vintage concrete to reduce seepage, repaved the road, replaced water and sewer lines, and installed energy-efficient led lighting. prior to the 2017 rehabilitation, the tunnel was the second-largest consumer of power in the entire golden gate national recreation area after district headquarters in san francisco .

  • headlamp

    a headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.. headlamp performance has steadily improved throughout the automobile age, spurred by the great .

  • fluorescent lamp

    a fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. an electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

  • fluorescent lamp

    compared with an incandescent lamp, a fluorescent tube is a more diffuse and physically larger light source. in suitably designed lamps, light can be more evenly distributed without point source of glare such as seen from an undiffused incandescent filament; the lamp is large compared to the typical distance between lamp and illuminated surfaces.

  • high-intensity discharge lamp

    high-intensity discharge lamps are a type of arc lamp. brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. however, the lumen output of hid lighting can deteriorate by .

  • sodium-vapor lamp

    a sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. two varieties of such lamps exist: low pressure and high pressure. low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting, such as street lamps, where they are widely used. high-pressure sodium lamps emit a broader spectrum of light than the low-pressure lamps, but they sti
