The Importance of Using a Lux Meter
The lives of people are directly tied to illumination. Having enough light can help people avoid accidents. In contrast, too little light might make people feel tired more than the eyes themselves. Therefore, one of the main factors contributing to accidents and weariness is uncomfortable or inadequate lighting. According to data currently available, inadequate lighting is either a direct or indirect cause of around 30% of all occupational work accidents. The lighting regulations for stadiums are highly rigorous; a game will be impacted by too much or too little light.、
What then are the hygienic requirements for the contrast lighting inside homes? A crucial indicator in hygiene is illumination. Light is the term used to describe electromagnetic radiation, which can appear bright to the human eye. Vision is the perception that can result from light entering the eye. Visible light has a wavelength range of 380 to 760 nm and is what most people can see.
There are two types of lighting: natural lighting and artificial lighting. Natural lighting is often expressed by daylighting coefficient and natural illuminance, and it refers to the natural illuminance of interior and regional spaces, including light scattered by direct sunlight and light reflected from nearby objects. The effective area of the daylight opening divided by the total area of the interior floor is known as the daylighting factor. A typical home has a living area ratio of between 1/8 and 1/10 (window area/indoor floor area), and its daylight factor ranges from 1/5 to 1/15. The amount of illuminance provided by natural light is measured using the natural illuminance coefficient.It reflects the relationship between indoor and outdoor light exposure. It also reflects the local light climate (the sum of the natural light energy and the sunlight illuminance index of the climate).

The amount of illuminance provided by natural light is measured using the natural illuminance coefficient.1500-2000Lx for shop windows; 150-200Lx for hospital wards, 500Lx for emergency treatment areas; 400-700Lx for schools and classrooms; canteens and indoor gyms For 300Lx etc.
Illuminance is often measured with an illuminance meter for this measurement type. The illuminance meter can accurately measure the intensity of several wavelengths (for example, the measurement of the visible light band and the UV band).
In other words, lighting and human health, especially eye care, have huge sanitary implications.
