WHAT IT IS AND WHAT IT MEANS<\/h2>\n

WHAT IS COLOUR TEMPERATURE<\/h3>\n

\"Color<\/p>\n

Colour temperature is given in Kelvin and is the code for the light colour of a light source.
\nThe British physicist William Thompson introduced the “thermodynamic temperature scale” Kelvin, which is still used today.
\nWe find information about the colour temperature on every light bulb package today.<\/p>\n

 <\/p>\n

MYSTERIUM COLOUR TEMPERATURE \/ KELVIN<\/h3>\n

The Kelvin values are not really tangible and familiar to us. So how can we imagine these numbers and what do they mean?<\/p>\n

CELSIUS vs. KELVIN<\/h4>\n

The unit Kelvin generally designates the “thermodynamic scale”. 0\u00b0 Celsius corresponds to 273.15\u00b0 Kelvin on this scale. However, the colour temperature is not the temperature or heat of the glow, but describes the “impression” that characterises a glow.<\/p>\n

The measurement is done by the experiment of the “black body” and it works like this:
\nSolid materials begin to glow with rising temperature, e.g. iron -> from grey it changes with rising temperature to a glowing red. In theory, there is the “perfect black body” that swallows all the light that hits it. If it is heated, it begins to glow sometime and shine with it. The hotter, the more it glows, the brighter and whiter the light it emits. From warm red tones to yellow to white and light blue.
\nThe colour temperature in Kelvin indicates how hot the body must be to radiate a certain light colour.<\/p>\n

\"Color<\/p>\n

For your understanding:<\/h4>\n

1500 K – Candle (very warm)
\n3000 K – Halogen lamp (pleasant)
\n5000 K – Morning \/ evening mood
\n5200 K – Midday sun
\n6400 K – Overcast sky
\n10000 K – Blue sky (high altitude)<\/p>\n

 <\/p>\n

It’s all very theoretical.
\nIn summary, there are three major types of light color for illuminants:<\/p>\n

\nWARM-WHITE<\/strong>
\nMoving in the 3300 Kelvin range. It is perceived as pleasant, warm and friendly because it resembles the natural light of the sunset. And brings us back the appearance of the good old light bulb.<\/p>\n

 <\/p>\n

NEUTRAL-WHITE<\/strong>
\nThe highest value for neutral white light is approx. 5300 Kelvin. The atmosphere is objective but friendly. Ideal for work or make-up.<\/p>\n

 <\/p>\n

DAYLIGHT-WHITE<\/strong>
\nOver 5600 Kelvin is called daylight white. Stimulating and concentration-promoting light colour with a high blue component. These light sources are suitable for large halls, factories, sales rooms and similar.<\/p>\n
