ultraviolet radiation

Voorbeeldzinnen

1. ultraviolet radiation: optical radiation of wavelength range between 100 nm and 400 nm.
2. optical radiation: any electromagnetic radiation in the wavelength range between 100 nm and 1 mm. The spectrum of optical radiation is divided into ultraviolet radiation, visible radiation and infrared radiation:
3. ultraviolet radiation: optical radiation of wavelength range between 100 nm and 400 nm. The ultraviolet region is divided into UVA (315-400 nm), UVB (280-315 nm) and UVC (100-280 nm);
4. Even sunscreen products which are very effective and which address both UVB and UVA radiation cannot guarantee full protection against healthrisks from ultraviolet (UV) radiation.
5. amending Regulation (EC) No 244/2009 as regards the ecodesign requirements on ultraviolet radiation of non-directional household lamps
6. ‘Specific effective radiant ultraviolet power’, which is the effective power of the ultraviolet radiation of a lamp weighted according to the spectral correction factors and related to its luminous flux (unit: mW/klm);
7. Light or sun lamps should not be the sole source of heat. The provision of ultraviolet radiation is necessary to stimulate the animal's production of vitamin D.
8. Development and co-ordination of early warning and surveillance systems in specific areas (e.g. cold spells, health effects of flooding, airborne allergens, ultraviolet radiation and vector borne and other human and animal infectious diseases). [Financing mechanism: Call for proposals]
9. ‘Second lamp envelope’ is a second outer lamp envelope which is not required for the production of light, such as an external sleeve for preventing mercury and glass release into the environment in case of lamp breakage, for protecting from ultraviolet radiation or for serving as a light diffuser;
10. ‘fluorescent lamp’ means a discharge lamp of the low pressure mercury type in which most of the light is emitted by one or several layers of phosphors excited by the ultraviolet radiation from the discharge. Fluorescent lamps are supplied either with or without integrated ballasts;
11. ‘luminaire’ means an apparatus which distributes, filters or transforms the light transmitted from one or more light sources and which includes all the parts necessary for supporting, fixing and protecting the light sources and, where necessary, circuit auxiliaries together with the means for connecting them to the supply, but not the light sources themselves; 7. ‘fluorescent lamps’ means discharge lamps of the low pressure mercury type in which most of the light is emitted by one or several layers of phosphors excited by the ultraviolet radiation from the discharge; 8. ‘fluorescent lamps without integrated ballast’ means single and double capped fluorescent lamps without integrated ballast; 9. ‘high intensity discharge lamps’ means electric discharge lamps in which the light producing arc is stabilised by wall temperature and the arc has a bulb wall loading in excess of 3 watts per square centimetre.
