Valgustus on tihedalt seotud seotud inimestega's elud. Piisav valgustus saab ennetada inimesed õnnetused. On vastupidi, too tume valgus võib põhjustada väsimus in inimene keha kaugel kaugemal silmad ise. Seetõttu, ebamugav või halb valgustus tingimused on üks peamine põhjused õnnetused ja väsimus. Olemasolev statistiline andmed näitab et umbes 30 protsent kõik tööõnnetused on otseselt või kaudselt põhjustatud poolt ebapiisav valgustus. Valgustus sport staadion (võimla) peaks olema väga range, as liigne või hämar valgustus saab mõjutada tõhusus võistlus.
So, what about the hygiene of indoor illumination in people's homes? illuminance is a very important indicator in hygiene. light refers to elektromagnetiline kiirgus et can cause a sense of brightness in the human eye. the perception that can be genereeritud when light enters the eye is called vision. the light that people see refers to visible light, with a wavelength range between 380 and 760nm (nanomeetrid).
Currently, lighting can be divided by two categories: natural lighting and artificial light sources. Natural lighting refers to the natural illuminance of indoor and regional areas, with direct sunlight scattering and reflected light from surrounding objects. It is commonly represented by lighting coefficient and natural illuminance. The lighting coefficient refers to the effective area of the lighting opening to the siseruumides põrand pindala. The lighting coefficient of general elamu hooned is between 1/{5-1/15, and the living area ratio is is between 1/8-1}/10 (window area/indoor floor area). The natural illuminance coefficient is used to erate the illuminance level of natural light. the reflects the relationship between indoor and outdoor light exposure. See ka peegeldab lokaalne valgus kliima ( summa loodus valgus energia ja päikesevalgus intensiivsus näitajad kliima).
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 general used for measurement. The illuminometer can measure the intensity of different wavelengths (such as in the visible and ultraviolett bands), anding täpne mõõtmine tulemused to inimesed.
In lühike, valgustus on äärmiselt oluline hügieen olulisus inimese tervise, eriti silma tervise jaoks.
