Lux Calculator – Lighting Calculator

The Lux Calculator for proper lighting of a hall

If you have to illuminate a hall or other larger room with LED spotlights, you should use a Lux calculator. Only then is it guaranteed that the room to be illuminated is adequately supplied with light. After all, it does not matter at all whether such an auxiliary computer is used or not. In the commercial sector, the trade associations check from time to time, among other things, whether rooms or workshops and halls are adequately supplied with light. You can only be really sure if a lighting computer is used. Another reason to use a Lux calculator is the financial aspect. Because a room could not only be too sparse, but also too illuminated. This does not only damage the eyes, but also the purse. Although LED spotlights consume significantly less than old bulbs, no more energy should be consumed than is necessary for proper illumination. With Pi times thumbs you don't get far, but you better use the Lux calculator. This is a good help in the commercial as well as in the private sector to illuminate correctly.

It is also called Lux Lumen Calculator

Sometimes this calculation is also referred to as a Lux lumen calculator. With a lux calculator, it is possible to calculated how much light is needed for the illumination of a room. The Lux unit is international and indicates the illuminance. The luminous flux, which falls on an area per square metre, is calculated in the unit lumens. One lux is one lumen per square metre. Candela is the radiation intensity used to send light through space. The earlier name for Candela was New Candle. It is still used colloquially sometimes, but is no longer valid. In addition to the candela, other factors play a role in the calculation.


Example without guarantee:

LED indoor spotlight – mounting height 8 meters = 200Watt indoor spotlight – cold white = 250Lux at normal room brightness

Other factors for the calculation

Other factors for calculating the illumination of a room are the room height and the beam angle of the LED spotlight. As far as the beam angle is concerned, it is variable for LED luminaires and can be very large. There are LED spotlights with a beam angle of up to 120 degrees. This wide radiation is made possible by built-in lenses and prisms specially developed for this purpose. The room height is of course also very important when it comes to calculating the perfect and proper illumination of a room.

Who works with a Lux calculator?

It is not only the operators of halls and workshops who should ensure the correct lighting with the help of the Lux calculator. Interior designers also work with this computer all the time when it comes to the planning and furnishing of houses and apartments. The private housebuilder should also consult such a lux calculator when the LED light sources are planned in the house. What sounds complicated is actually quite simple, because it takes only a few data to get concrete results with this calculator. Overall, this simple calculator is a good support, especially when planning light sources in large buildings and halls, where sufficient brightness must be guaranteed.
