... indicates how much luminous flux is incident on a given surface. The unit of measurement is lux (lx). The formula for illuminance is: luminous intensity in candela (cd) divided by the distance2(/radius2) between light source and surface..
... indicates the color temperature (CCT) in Kelvin (K). It is used to describe the light. For the exact determination, however, the temperature of the Plank's radiator is needed..
... is a form of individual lighting control. A dimmer can be used to set the desired brightness of a luminaire and adapt to its tasks..
Energy efficiency classes
… is a rating scale for the European energy label. Every device that consumes energy is divided into these classes by the EU. Energy efficiency class A means low energy consumption, B and C mean energy consumption, all other classes mean very high consumption and should be avoided. werden.
… is a measure to quantitatively determine the color impression of a light source. A distinction is made, for example, between warm white, neutral white and cold white. The unit of color temperature is Kelvin (K).
... is the unit of color temperature and describes the color of a light source. (see also CCT and color temperature). Cozy light has 2000 to 3300 Kelvin, cold, radiant light as in large warehouses has over 5300 Kelvin. LEDs, for example, can cover the entire span.
… steht für Licht emittierende Diode und bezeichnet ein elektronisches Halbleiter-Bauteil, welches bei Stromdurchfluss Licht ausstrahlt. Led´s sind sehr sparsam im Vergleich zu herkömmlichen Glühlampen, haben eine wesentlich höhere Lebensdauer und können eine große Spannweite an Farbtemperaturen wiedergeben.
... is a measure of the efficiency of light sources. It indicates how much energy is required for a given luminous flux. The luminous efficacy is given in lumens per watt (lm/W). The rule is: the higher the value, the better the yield.
... is the spectral composition of a self-luminous light source. It is also determined by the triggered stimulus in the eye and brain. It is used to characterize a light source and is represented, for example, by the light and color temperature..
... indicates the radiant flux of a light source in lumens and provides information about how brightly a lamp shines. However, the luminous flux is difficult to measure, better suited are the specifications lumens or lux.
... indicates how much light a light source emits in total per time unit. This value describes the brightness of a light source and is by the adjustment of the luminous intensity unit candela, a good indication of your required power..
... is the physical unit for the illuminance of a light source. It indicates how much luminous flux from a light source falls on a surface. A lux meter is used to check whether a light source is bright enough. You can also find the calculation under - Illuminance.
... are illuminants with which you can easily replace ''old'' light bulbs with LED - bulbs, because they are compatible with conventional sockets. Halogens can also be replaced by LEDs..
... is the unit for electrical voltage. Here, volts describes the amount of energy present in individual electrons. Formula symbol: U
