Description
Technical field
The present invention relates to lighting field, particularly relate to a kind of means of illumination based on thermometric colour temperature self-adaptative adjustment.
Background technology
Colour temperature is the index representing that light source light spectrum quality is the most general.Generally represent with Tc.
Colour temperature defines by absolute black body, and the radiation of light source is when visual field is identical with the radiation of absolute black body, and now the temperature of black matrix just claims the colour temperature of this light source.
The feature of low color temperature light sources is in Energy distribution, and red radiation is said some more relatively, is commonly referred to " warm light "; After colour temperature improves, in Energy distribution, the ratio of blue radiation increases, and is commonly referred to " cold light ".The colour temperature of some Ordinary Light Sources Haves is: standard candle is 1930K(kelvin degree unit); Tungsten lamp is 2760-2900K; Fluorescent lamp is 3000K; Photoflash lamp is 3800K; Noon, sunlight was 5600K; Flash tube is 6000K; Blue sky is 12000-18000K.
When discussing colour phhotograpy optical issue, the concept that photographer often mentions " colour temperature ".What colour temperature refers to actually
We know, the light seen by usual human eye, superposed formed by the spectrum of 7 kinds of coloured light.But wherein some light is partially blue, some is then partially red, colour temperature is exactly be used for measuring the method with the color component of compute ray specially, founded by English physicist Lip river moral Kelvin for 19 end of the centurys, he has made a whole set of colour temperature meter algorithm, and the standard that it is specifically determined is the wavelength based on sending with a blackbody radiator.
Colour temperature (ColorTemperature) is high-grade display performance index.We know, can produce one group of spectrum during light source luminescent, and the required a certain temperature reached when producing same spectrum with a black body, this temperature is exactly the colour temperature of this light source.More than 15 inches present numerical control displays, certainly with colour temperature regulatory function, can enable the color of display meet high standard job requirement by this function (generally having 9300K, 6500K, 5000K tri-selection).In expensive goods, some also supports colour temperature Serial regulation function.
The color of light source is commonly used this concept of colour temperature and is represented.The color of source emissioning light and black matrix at a certain temperature radiant light form and aspect simultaneously, the temperature of black matrix is called the colour temperature of this light source.In black body radiation, along with temperature is different, the color of light is different, and black matrix presents by the red---orange red---yellow---yellowish-white---progressive formation that in vain---indigo plant is white.The color of the light that certain light source is launched, when seeming identical with the light color that black matrix is launched at some temperature, this temperature of black matrix is called the colour temperature of this light source.The temperature of " black matrix " is higher, and composition blue in spectrum is then more, and the composition of redness is then fewer.Such as, the photochromic of incandescent lamp is warm white, and its colour temperature is expressed as 2700K, and the colour temperature method for expressing of daylight fluorescent lamp is then 6000K.
Some charging source, its radiative color and launched the at various temperatures light color of black matrix all incomplete same.So use the concept of " correlated colour temperature " in this case.The color of the light that the color of the light that light source is launched and black matrix are launched at a certain temperature closest to time, the temperature of black matrix is just called the correlated colour temperature of this light source.
Light source color temperature is different, and photochromic different, the sensation brought is not identical yet yet:
1. when being less than 3300K, photochromic warm (white with red), steady to people, warm sensation;
2., time between 3000-5000K, photochromic centre (white), to the sensation of people's frankness;
3., when being greater than 5000K, photochromic refrigerant (white that band is blue), to the sensation that people is cold.
Under high color temperature light source irradiates, as brightness is not high, there is a kind of sombre atmosphere to people; Under low color temperature light sources irradiates, the too high meeting of brightness has a kind of sultry sensation to people.
When ambient temperature is higher, we wish to see cold light source, and the light source that namely colour temperature is larger give refrigerant sensation, and when ambient temperature is on the low side, we wishes to see thermal light source, the light source that namely colour temperature is less, give warm sensation.Existing illuminator generally only uses a kind of light source, and its colour temperature is fixing, can not adjust.
