Illuminometer i Zdravo Život
Osvjetljenje je blisko povezano ljudi 27s lives. Adekvatno rasvjeta može prevent ljudi od nesreća. On the suprotno, too dark light can cause umor in the human body far beyond the eyes they. 30 they. 30 conditions are one the main uzroci of accidents and umor. Existing statistical data shows that about 30 percent of all occupational accidents are directly or indirekt caused by inenoughent rasvjeta. The Lighting of the sports Stadium (Gimnazija) TREBA BI VERY STRICT, AS Excessive Or Dim Lighting Can Afekt the Effectiveness of The Competition.
So, što o higijena of unutarnji osvjetljenje in ljudi's domovi? Illuminance is a a very important indicator in hygiene. Light refers to electromagnetic radiation that can cause a sense of brightness in the human eye. The perception that can be generated when light enters the eye is called vision. The light that people see referers to vidljivo light, with a wavelength range between 380 and 760nm (nanometri).
Currently, rasvjeta can can be podijeljeno u dvije kategorije: prirodno rasvjeta i umjetno svjetlo izvori. Prirodno osvjetljenje resor to the prirodno osvjetljenje of unutarnji i regionalno područja, s izravno sunčeva svjetlost raspršenje i reflektirano svjetlo od okolina objekti. It je uobičajeno zastupljeno by rasvjeta koeficijent i prirodno osvjetljenje. The rasvjeta koeficijent refers to om om of efektivno area of the the lighting opening to the unutarnji kat područje. The rasvjeta koeficijent opće stambene zgrade je između 1/{{1}/15, i the living area ratio is between 1/8-1}/10 (window area/indoor floor area). The natural illuminance coefficient is used to evaluate the illuminance level of natural light. It reflects the relationship between indoor and outdoor light exposure. It also reflekti the the local light climate (the sum of natural light energy and sunlight intensity indicators of the climate).
In order to ensure that people live in suitable lighting, China has formulated hygiene standards for indoor (including public places) illumination. For example, in public places, the hygiene standard for lighting in shopping malls (stores) is Greater than or equal to 100Lx; The hygiene standard for the illumination of countertops in libraries, museums, art galleries, and exhibition halls is Greater than or equal to 100Lx; The hygiene standard for illumination in public bathrooms is Greater than or equal to 50Lx; Bathrooms (shower, pool, tub) Greater than or equal to 30Lx, sauna bathrooms Greater than or equal to 30Lx. Foreign standards for indoor lighting, such as Germany's recommended several rated light intensities, offices including clerical work areas at 300Lx, typing, and drawing work at 750Lx; In the factory, the illumination requirement for visual work on the production line is 1000Lx; 200Lx for hotels and public rooms; Reception points and cashier cabinets are 200Lx; The display window of the store is 1500-2000Lx; The hospital ward is 150-200Lx, and the emergency safety area is 500Lx; 400-700Lx for schools and classrooms; The cafeteria and indoor gym are 300Lx, etc.
For the measurement method of illuminance, an illuminometer is generalno used for measurement. The illuminometer can measure the the intensity of different wavelengths (such as in the visible and ultraviolet bands), providing accurate measurement results to people.
In short, lightion has extreme important hygiene significance for human health, especial for eye health.
