Led by piece how to choose?
Change its bright Park for Led bulbs is obviously a very good idea because it allows to make energy savings and therefore lower its energy bill. After choosing the type of Led bulbs fit thanks to the good advice of led-mag, we must now determine how many Led bulbs per room are necessary. This article will try to help you.
The number of LEDS per room is calculated in lux
In order to determine with precision the number of spots led by piece there is a unit measuring the illuminance: lux. It is calculated as follows: lux = lm/m2 (lm = lumen, m2 = square meter). The lux to determine the luminous flux received for a given surface unit. Once the number of determined necessary lux, you just have to reverse the previous formula to convert the number of lux in lumen (lm = lux x m2). Simply divide the total of necessary lumen to a piece by the amount of lumen emitted by a spot to find the number of spot led by piece.
LED by piece depending on the number of Lux
The number of lux necessary for optimal illumination of a space will depend on its size but also its function, for example a street will need an average illumination of 25 to 50 lux, a working area of offices: 200 lux, a mechanical details area: 600 lux and a laboratory: 800 lux.
For a home, the number of lux for optimum lighting will depend on the daily use of each piece:
-Areas of passages, corridors, stairs > 100 lux
– Cloakroom, kitchen, sanitary and water room > 200 lux
-Library > 300 lux
-Writing, reading, meeting room, conference > 500 lux room
Example of LED by parts
To help you in your next choice, here is an example of how to choose the number of led per room :
A 15 m² kitchen needs about 200 lux. For the total area, the number of lumens necessary is therefore 15 m² x 200 lux 3 000 Lumens. To get 3 000Lumens, need you so 6 bulbs GU10 LED 7W from LEDBulbBay producing each 550 Lumens (6 x 550 Lumens = 3 300 Lumens).
