Lux Meter

A Lux meter is an instrument used to measure the intensity of light in terms of illuminance, expressed in lux (lx). It is commonly used in workplaces, laboratories, photography, agriculture, and safety inspections to ensure proper lighting conditions for efficiency, comfort, and compliance with standards. The device typically consists of a light sensor (photodiode or photoresistor) connected to a digital or analog display unit. The sensor detects the amount of light falling on it and converts it into an electrical signal, which is then processed and displayed in lux.

Lux meters are vital in industries where lighting affects visibility, accuracy, and safety, such as offices, factories, hospitals, and mining sites. They help in designing lighting systems, evaluating natural and artificial light sources, and ensuring energy efficiency. Proper use of a lux meter ensures compliance with occupational health and safety standards, reduces eye strain, and creates a safe and productive environment.
