Lux Monitoring
Intensity of light perceived to human eye. It is the unit of luminance. Lux levels can be measured to get uniformity of light in an area. As per Factories Act the minimum light levels should not exceed 500 Lux as it measures the intensity of light hitting a surface typically a wall or a floor . One lux is equivalent to one lumen per square meter. They differ from lumens, which measure the brightness of the light source.
A lux meter is a device for measuring brightness, specifically, the intensity with which the brightness appears to the human eye. A lux meter works by using a photo cell to capture light.
One lux is equal to one lumen per square meter, and they vary from lumens, which calculates the brightness of the source of light. Therefore, 1 LUX = 1 Lumen / m2. Enough light should be provided in the area so that people perform their tasks without any mishaps and hassles.
Major contaminates in Lux Monitoring:
- Metals, metalloids and their compounds
- Acids and alkalis; Asbestos
- Coal tar components including phenols
- Poly- cyclic aromatic hydro-carbons (PAHs)
- Fuel oils and coal
- Waste organic compounds (can be chlorinated)
- Poly-chlorinated biphenyls (PCBs)
Some ways to improve Lux Monitoring:
Lighting larger areas to the same necessary lux levels will requires a larger measured level of lumens – this is usually achieved by increasing the number of light fixtures (and hence the power consumed).
Over time, factors like sensor degradation, temperature changes, and environmental conditions can impact a lux meter’s accuracy.
