Definition of color temperature in English English dictionary
A measurement of the color of light radiated by an object while it is being heated This measurement is expressed in terms of absolute scale, or degrees Kelvin Lower Kelvin temperatures such as 2400°K are red; higher temperatures such as 9300°K are blue Neutral temperature is gray, at 6504°K
A numerical description of the color of light It is the temperature in degrees Kelvin (K) to which a perfect black-body radiator (an object that does not reflect any light falling on it) would have to be heated to produce a given color
A scientific measurement of the balance of wavelengths making up any "white" light The unit of measurement is the Kelvin, abbreviated K Although it may not seem sensible, a higher color temperature means a cooler, bluer light source Typical color temperatures are 2800°K (incandescent), 3200°K (halogen) and 5500°K (daylight)
The temperature of the Planckian radiator whose radiation has the same chromaticity as that of a given stimulus
Description of the color of a light source Measured on a scale of degrees Kelvin
An estimate of the temperature of an incandescent body, determined by observing the wavelength at which it is emitting with peak intensity (its color) and using that wavelength in Wien's law
Originally, a term used to describe the "whiteness" of incandescent lamp light Color temperature is directly related to the physical temperature of the filament in incandescent lamps so the Kelvin (absolute) temperature scale is used to describe color temperature For discharge lamps where no hot filament is involved, the term "correlated color temperature" is used to indicate that the light appears as if the discharge lamp is operating at a given color temperature More recently, the term "chromaticity" has been used in place of color temperature Chromaticity" has been used in place of color temperature Typical color temperatures are 2800K (incandescent), 3000K (halogen), 4100K (cool white or SP41 fluorescent), and 5000K (daylight-simulating fluorescent colors
- Is a term used to describe the color of light from a source compared to a Blackbody It is often described in degrees Kelvin (0 K)
A measure of the color of a light source relative to a black body at a particular temperature expressed in degrees Kelvin (°K) Incandescent lights have a low color temperature (approximately 2800°K) and have a red-yellowish tone; daylight has a high color temperature (approximately 6000°K) and appears bluish (the most popular fluorescent light Cool White is rated at 4100°K) Today, the phosphors used in fluorescent lights can be blended to provide any desired color temperature in the range from 2800°K to 6000°K
a measure of the color appearance of a light source which helps describe the apparent "warmth" (reddish) or "coolness" (bluish) of that light source Generally, light sources below 3200K are considered "warm;" while those above 4000K are considered "cool" light sources
Originally, a term used to describe the whiteness of incandescent lamp light Color temperature is directly related to the physical temperature of the filament in incandescent lamps so the Kelvin(absolute) temperature is used to describe color temperature For discharge lamps where no hot filament is involved, the correlated color temperature is used to indicate that the light appears as if the discharge lamp is operating at a given color temperature More recently, the term chromacity has been used in place of color temperature Typical color temperatures are 2800K (incandescent), 3000K (halogen), 4100K(cool white or Sp41 fluorescent) and 5000K (daylight simulating colors )
A measurement of the color of white light, expressed in Kelvins (The Kelvin scale is a measure of temperature, starting from absolute zero ) The color temperature is the color of light a perfect black-body radiator emits when heated to that temperature Computer monitors typically have a color temperature of 5000-9300 Kelvins: 5000 Kelvins is a yellowish-white, 9300 Kelvins is a blue white
1 An estimate of the temperature of an incandescent body, determined by observing the wavelength at which it is emitting with peak intensity (its color) and using that wavelength in Wien law
A means of measuring the relative redness or blueness of a light source; measured in degrees kelvin (K); higher numbers produce bluer light Typical incandescent bulbs are approximately 3,200 degrees K, while daylight is about 6,500 degrees K
Temperature of the black body that emits radiation of the same chromaticity as the radiation considered Unit Kelvin, K
The absolute temperature of a blackbody radiator having a chromaticity equal to that of the light source (see correlated color temperature)
The quality-expressed in degrees Kelvin (K)-of the light source The higher the color temperature, the bluer the light, the lower the temperature, the redder the light
the temperature at which an object emits its specific wavelength of light, expressed in degrees Kelvin (K)
A black body, whose radiation is solely the result of thermal activity, emits a characteristic spectrum that is determined exactly by its surface temperature Light sources that approximate such a spectrum, such as incandescent lamps, are often characterized by their correlated color temperature, given in degrees Kelvin
Color temperature is a term used to describe the color of a light source, by comparing it with the color of a "blackbody " A blackbody is a theoretical "complete radiator", changing its color as its temperature is raised It first glows dull red, then bright red, moving through orange, yellow, white, bluish white and finally blue The color of a candle fame is similar to a blackbody at about 1800°K A common household tungsten light bulb produces an average color temperature of 2800°K, whereas sunlight is about 5500°K
A numerical description of the color of light It is the temperature in degrees Kelvin (°K) to which a perfect black-body radiator (an object that does not reflect any light falling on it) would have to be heated to produce a given color
The characteristic of a color which makes it appear either warm or cool in feeling Red, orange, and yellow are usually considered warm while colors containing blue are thought of as cool
Refers to scale used for rating the color quality of illumination When a "blackbody" is heated, its color changes from black to red, yellow, blue, then white as the temperature rises Color temperature matches the actual temperature of the heated blackbody Measured in Kelvins (K) The temperature of daylight on a sunny day, for example, is expressed as 5500K; that of light from a tungsten lamp is expressed as 3200K to 3400K
The absolute temperature at which a black-body radiator must be operated to have chromaticity equal to that of that light source
