| Details | In the field of illuminance, lumen per square kilometre (lm/km²) is a unit used to measure the luminous flux (the perceived power of light) per unit area. It describes the amount of visible light illuminating a surface, and helps to quantify the brightness or intensity of light over an area. The basic unit for measuring illuminance is lumen per square meter (lm/m²), which is also known as lux. In some cases, a larger unit may be necessary to describe large-scale lighting situations, such as street lighting, outdoor lighting, or large-scale architectural lighting. This is where lumen per square kilometre (lm/km²) comes into play, as it represents the illuminance over an area of one square kilometre. To understand this, it's essential to understand the components: 1. Lumen (lm): A unit of measurement for the total amount of visible light emitted by a source, representing the perceived power of light. 2. Square kilometre (km²): A unit of measurement for area, representing a square with sides of one kilometre in length. So, when we combine these units, we get lumen per square kilometre (lm/km²), which measures the density of the illuminance over an area of one square kilometre. In other words, it quantifies how much visible light is emitted and spread across a large surface area. |
