Morning begins not with coffee, but with dawn. Indeed, it is at this moment that the powerful «lumenowatts» of the Sun begin to flood the horizon and the world is illuminated by warm sunlight with a color temperature of 3400 Kelvin.
Many people divide artificial light into «warm» and «cold». Most often, we mean the shades of light emission. The concept of «light temperature» (or «color temperature») is of great importance for the creation of correct and high-quality architectural lighting. Color temperature is a physical concept that denotes the «shade» of the luminous flux emitted by a light fixture: from the yellowish warm, which is produced by incandescent lamps, to the bluish or cool white, emitted by fluorescent lamps. Zero color temperature (0 Kelvin) has an absolute black color.
In the process of creating an architectural lighting project, it is necessary to take into account the color of the facade. Unfortunately, warm light sources work on «cold» facades - in this case, it is recommended to select colder light for them, about 4000-5000 K. Thus, warm light is more suitable for natural wood shades, and cold light for metal ones. But don't make a real New Year tree out of the building's facade! «Color disco», which will irritate the eyes and lead the human body to the wrong mode, will be unpleasant for the harmony of colors.
The color temperature of light sources is usually indicated in the equipment passport documentation. But of course, for a better result when designing lighting, involve specialists, since in addition to simple principles for selecting a thermal temperature in a commercial lighting device, there are a number of important points that must be taken into account when developing it.
