ILLUMINANCE Meaning and
Definition
-
Illuminance is a term used in optics and lighting to describe the amount of light that falls upon a surface per unit area. It is primarily concerned with measuring the brightness or intensity of light incident on a specified surface. Illuminance is measured in units of lux (lx), which represents one lumen of light per square meter.
In practical terms, illuminance refers to the amount of light that is available in a particular area or room. It is an important parameter in designing lighting systems, as it determines the overall level of brightness and visibility in a given space. Illuminance plays a crucial role in various applications, such as architecture, photography, horticulture, and workplace safety.
The value of illuminance is affected by factors such as the distance from the light source, the angle of incidence, and any obstructions or reflective surfaces present. It is influenced by the total luminous flux emitted by the light source and how that flux is distributed over the surface area.
Furthermore, illuminance is closely related to human perception of light. It helps determine the comfort and functionality of a space, influencing visual acuity, mood, and productivity. Various lighting standards and recommendations have been established based on illuminance levels for different environments and tasks.
In summary, illuminance refers to the measure of light intensity falling on a surface and is expressed in lux. It is a fundamental parameter in lighting design, affecting visibility and ambiance in different applications.
