![]() ![]() This is comparable to the brightness of a candle flame, which also reaches an illuminance of around one lux at a distance of one metre. A light source with a luminous flux of one lumen which uniformly illuminates an area of one square metre has an illuminance of one lux. ![]() Theo mt cách khác: Thông s k thut tính bng lux cho bn bit bn cn bao nhiêu Lumen (tng lng ánh sáng phát ra) cho khu vc c o mà bn ang c gng chiu sáng. The unit to measure the illuminance is Lux. Mt lux (1 lux) c nh ngha là tng ng vi mt lumen tri rng trên din tích mt mét vuông. Therefore, we need to pay attention of the value of lumens! With lux, measure the amount of light which is visible in an area. Toelichting: We streven naar nauwkeurige en actuele informatie, maar het kan voorkomen dat de informatie na verloop van tijd verouderd, incorrect en/of incompleet is. A lux is the same as a lumen per square metre. Lux is the number of dots that fall on a. In our graphic below, each yellow dot represents a unit of brightness. Lumens is a measure of luminous flux, the total amount of light emitted in all directions. Lux is a measure of illuminance, the total amount of light that falls on a surface. In other words, a brand ’A’ 10W LED bulb may giving less light than brand ‘B’ 8W LED bulb. U kunt zelf berekenen hoeveel lumen u nodig denkt te hebben, dit doet u door middel van de volgende formule: Aantal m2 x aantal lux aantal benodigde lumen. The difference between lux and lumens by definition. This caused us all to give place for different power and different lumen value’s. However, the power of LED technology is evolving. See the table below to get an idea about the light source and the Luminous flux these gave us We often buy our light bulbs according to their watt consumption without knowing the amount of light they project. We are all familiar with the traditional fluorescent tube (18W,36W and 58W) or with an 250W or 400W HPS or the Halogen 1000W and 2000W and how much light these light sources gave us. The unit of the luminous flux is lumen (lm). Luminous flux expresses to the total amount of light, in all directions and emitted by a lighting element. ![]()
