Handbook of Advanced Lighting Technology pp Cite as. Photobiology is a scientific field that involves biology, physics and chemistry in order to study the effects of optical radiations on living organisms. Lighting systems are sources of artificial optical radiations used primarily to provide light to the human eye in order to enable visual processes in the absence of enough daylight. The first photobiological effect of a visible light source is vision itself. Photobiological safety refers to the undesirable effects of optical radiations on human tissues, especially the skin and the eye. These effects have several possible causes, according to the exposed tissue, the wavelength of the incident radiation, the intensity of the exposure and the duration of the exposure. According to these parameters, the effects can be temporary reversible , or permanent in the case of severe exposures.

TUV Rheinland launches photobiological safety lab in Korea

Back to overview. State-of-the-art photobiological safety testing facility will help Korea-based manufacturers target global markets safely and speedily. The new facility will help Korea-based manufacturers of LED products and lighting systems to target local and international markets, including the European Union, safely and speedily. It is authorized to test products and issue ENEC certifications — an essential qualification for any lighting equipment vendor interested in entering any EU market.

This is why many newly built or modernized industrial facilities are equipped with lighting systems based on LED technology. The quality of LED luminaires is particularly important because of the higher environmental requirements their operation is subject to in industrial facilities, as well as their expected level of reliability. Lighting of work places.

T he EN standard is one of the most important documents discussing photobiological hazards. The standard defines principles which should be followed to assess photobiological hazards and safety of artificial and natural sources of optical radiation. It covers all kinds of sources emitting optical radiation in a very wide range of wavelength — in ultraviolet, visible spectrum and far infrared. Presence near the emitting source, depending on its type, can lead to injuries and even to serious illnesses. Persons exposed to ultraviolet, visible or infrared radiation, can have the biological tissues of their eyes and skin damaged. Conjunctivitis, keratitis and erythema are frequent consequences of ultraviolet radiation.

Его редеющие седые волосы спутались, и даже несмотря на прохладу, создаваемую мощным кондиционером, на лбу у него выступили капельки пота. Его костюм выглядел так, будто он в нем спал. Стратмор сидел за современным письменным столом с двумя клавиатурами и монитором в расположенной сбоку нише. Стол был завален компьютерными распечатками и выглядел каким-то чужеродным в этом задернутом шторами помещении. - Тяжелая неделя? - спросила .

 Может. - Может. - Мы должны позвонить ему и проверить. - Мидж, он же заместитель директора, - застонал Бринкерхофф.  - Я уверен, у него все под контролем. Давай не… - Перестань, Чед, не будь ребенком.

Молчание. - Мидж. Ты меня слышишь.

Сьюзан вдруг поняла, что смеется и плачет одновременно. Коммандер спас ей жизнь. Стоя в темноте, она испытывала чувство огромного облегчения, смешанного, конечно же, с ощущением вины: агенты безопасности приближаются. Она глупейшим образом попала в ловушку, расставленную Хейлом, и Хейл сумел использовать ее против Стратмора.

На полу возле тела Хейла лежал листок бумаги.
