The terms Lumen Lux Candela Luminance refer to units of illumination. Lighting units related to lm, lx, cd and cd/m2;
- Ø – Luminous Flux – Lumen (lm)is the total amount of light produced by a light source in all directions. It is the luminous flux. It is an indicator of the luminaire's light power.
- I – Light Intensity – Candela (cd)indicates the amount of light coming from a light source to any point in a single direction. It is the intensity of light. It is measured from a single point.
- E – Luminous Violence – Lux (lx) (lm/m2)indicates the amount of luminous flux reaching one square metre of surface. It is the brightness level of the environment. It is measured from the environment.
- L – Glitter – (Cd/m2)is the light intensity coming to the eye from the unit surface. In other words, it is the light intensity per 1 square metre.
Conclusion;
- 1 lux is the measurement of 1 lumen luminous flux in 1 square metre. Light of 1 candela intensity provides illumination of 1 lux at a distance of 1 metre. The brightness level, i.e. the perceived brightness level, varies depending on the properties of the surface.
