The color temperature of a light source is defined by comparing its color within the light spectrum with that of the light emitted by a black body heated to a given temperature. The unit of measure is the Kelvin (K), sometimes called Kelvin degrees.


Led and color temperature

 One of the main advantages of LED is that in its manufacturing process it determines the color temperature to be obtained. (It depends on the chemical compound that is combined such as Gallium, Indium, Aluminum, etc.). Thanks to this technology, LED lighting products emit light only in the light spectrum for which they have been manufactured, and do not emit radiation in frequencies such as ultraviolet or infrared as it happens with other technologies such as fluorescents (tubes or light bulbs of low consumption) And incandescent lamps that can damage objects that light up.

Usually, in LEDs, there are 3 color temperature groups:

  • Light Warm: (Color temperatures between 2800ºK and 3500ºK). It is equivalent to the light produced by incandescent bulbs and halogen bulbs. gaminator 777: ingyen nyerőgépek, kaszinó, játékok It is recommended in clothing stores, fruit shops, bakeries and butchers (the latter 2 is more usual even a pink tone lighting). In the case of housing, it is recommended to install it in rooms such as the living room and bedrooms.
  • Neutral light: (Color temperatures between 3800ºK and 4500ºK) experts say that it is the most natural light. It can be installed in any environment that does not require the specific nuance of the other 2 categories.
  • Cold Light: (Color temperatures over 5000 ° K). Is equivalent to the light of a very sunny or very cloudy day. One of the advantages of cold light is that at the same intensity brings a greater amount of lumens which generates a greater perception of luminosity. gaminátor pc It is a highly recommended light for fishmongers and jewelers. With respect to housing, it is usual  Find it in kitchens and bathrooms. Although the experts in makeup always recommend warm lice as they have the advantage of providing a better color range.

Warm, Neutral and Cold Lights

Warm light sources are called those that, due to their color temperature, have shades close to red and cold ones that have shades close to blue. Light sources in the middle of both are considered neutral. An interesting case is the light we perceive from the sun, which varies its color temperature depending on the time of day or the presence or absence of clouds. This is due to the fact that sunlight has to pass more or less amount of gases in the atmosphere according to the time of day and its position in the sky, or according to whether or not there are clouds, thus absorbing the high frequencies of the Light, that is, the range blue / ultraviolet (except for those with the ozone hole above), leaving a more reddish (warm) light, especially at dawn and dusk.

In certain types of lights, such as fluorescents and some of which illuminate roads and public places, the color temperature is a mean, since the light they emit is not of the same type as a normal bulb. kocsmai nyerőgépes játékok ingyen In traditional light bulbs, light is produced by incandescence, while fluorescents are generated by electric discharge in a gas. In the cases of gas discharge, there is a lack of colors in the light that radiate, which for misfortune vary between manufacturers and types of lights, and make it very difficult to see objects with real colors.

To get an idea of ​​how light affects color, consider a room with white walls with light wood furniture. If you light it with warm lights, you will accentuate the brown tones of the furniture and the walls absorb the color and a yellowish tone stands out. The set will have a very nice warm look. However, if we illuminate the same room with cold lights, the green and blue tones of furniture and walls will accentuate giving a cold appearance to the room.
