26、en industry-wide safety standards were not common. The evaluation and control of lamp hazards is a far more complicated subject than similar tasks for a single-wavelength laser system. The required radio-metric measurements are quite involved, for they do not deal with the simple optics of a point s

27、ource, but rather with an extended source which may or may not be altered by diffusers or projection optics. Also, the wavelength distribution of the lamp may be altered by ancillary optical elements, diffusers, lenses, and the like, as well as variations in operat-ing voltage.To evaluate a broad-ba

28、nd optical source, such as an arc lamp, an incandescent lamp, a fluorescent lamp, an array of lamps or a lamp system, it first is necessary to determine the spectral distribu-tion of optical radiation emitted from the source at the point or points of nearest human access. This accessible emission sp

29、ectral distribution of interest for a lighting system may differ from that actually being emitted by the lamp alone due to the filtration by any optical elements (e.g., projection optics) in the light path. Secondly, the size, or projected size, of the source should be characterized in the retinal h

30、azard spectral region. Thirdly, it may be necessary to determine the variation of irradiance and pro-jected radiance (see the Glossary) with distance. The performance of the necessary measurements is not an easy task without sophisticated instruments. Users should normally rely upon the expertise of

31、 manufacturers for information on lamps and lamp systems. Safety requirements and reference mea-surement techniques for lamps and specific lamp systems are provided in later standards of this series (i.e., ANSI/IES RP-27.2-00/R2010 Recommended Practice for Photobiological Safety for Lamps in these c

32、ases, the spectral characteristics of the source and detector are of importance.3.11 LampThe generic name for a man-made source of light is “lamp.” As used in this standard, the term means an electrically powered source, other than an LED used in a fiber-optic communication system or a laser. By ext

33、ension, the term is also used to denote sources that radiate in regions of the spectrum adjacent to the visible region, i.e., in the ultraviolet and infrared spectral ranges. Devices that gener-ate light and have integral components for optical control, such as lenses or reflectors, also are con-sid

34、ered lamps. Examples include a lens-end lamp, and a PAR (parabolic reflector) lamp with a reflec-tor or lens cover.Note: A device consisting of a lamp with shade, reflector, enclosing globe, housing, or other acces-sories has often been called a “lamp.” However, in this standard, a lamp with such ot

35、her components is termed a “lamp system” to distinguish between the assembled unit and the light source within it.3.12 Lamp SystemAny manufactured product or assemblage of com-ponents which incorporates, or is intended to incor-porate a lamp is considered to be a “lamp system,” e.g., a luminaire.3.1

36、3 Lamp PackagingAny carton, outer wrapping, or other means of con-tainment that is intended for the storage, shipment, or display of a lamp(s) or that is intended to identify the contents or to recommend its use is considered to be “lamp packaging.”3ANSI/IES RP-27.1-15 3.14 Minimal Perceptible Eryth

37、ema (MPE)The minimum erythemal dose (MED) is the radiant exposure density, e.g., Jm-2, that is just sufficient to elicit a perceptible delayed erythema, i.e., a minimum perceptible erythema (MPE). The MED varies with skin type, time between exposure and evaluation, and ultraviolet spectral distribut

38、ion (see Section 3.3).3.15 Ocular Hazard DistanceThe distance from a source within which the “project-ed radiance” (see Glossary) or irradiance exceeds the applicable exposure limit for momentary (0.25 s) viewing.3.16 PhotokeratoconjunctivitisAn inflammatory response of the cornea and conjunctiva fo

39、llowing exposure to ultraviolet (UV) radiation.Wavelengths shorter than 320 nm are most effective in causing photokeratoconjunctivitis. The peak of the action spectrum is approximately at 270 nm.3.17 Pulsed LampA lamp that delivers its energy in the form of a single pulse or a train of pulses where

40、each pulse shall have a time duration of less than 0.25 s.Note 1: The duration of a lamp pulse is the time inter-val between the half-power points on the leading and the trailing edges of the pulse.Note 2: In this standard, GLS lamps are defined to be Continuous Wave lamps (see Section 3.2). Example

41、s of pulsed lamps include photoflash lamps, flash lamps in photocopy machines, and strobe lights.3.18 Retinal Thermal HazardA photochemical or thermal retinal lesion.3.19 Retinal Hazard Spectral RegionThe spectral region from 380 nm to 1400 nm (vis-ible plus IR-A) within which the normal ocular medi

42、a transmit optical radiation to the retina.3.20 Skin Hazard DistanceThe distance at which the irradiance exceeds the applicable RG-2 emission limit for TWA (time weight-ed exposure) exposure.3.21 Time-Weighted-Average (TWA) ExposureThe time-integrated-average exposure equivalent to that which would

43、apply to the exposure dose of a potential photochemical (UV or blue-light) hazard without the movement of the individual or the source (refer to Section 3.1 for distance information).3.22 Ultraviolet RadiationFor practical purposes, UV radiation is any radiation within the wavelength range from 100

44、nm to 400 nm. The UV-C extends from 100 nm to 280 nm, UV-B from 280 nm to 315 nm, and UV-A from 315 nm to 400 nm as defined by the Commission Internationale de lEclairage (CIE). Frequently in some sub-sectors of photobiology, the wavelength bands are taken as UV-C from 200 nm to 290 nm, UV-B from 29

45、0 nm to 320 nm, and UV-A from 320 nm to 400 nm. Ultraviolet radiation at wavelengths less than 180-200 nm is considered vacuum ultraviolet radiation. Note that the radiation between 380 nm and 400 nm is also considered visible radiation (see Section 3.21) although it also is within the formal defini

46、tion of the ultraviolet band the overlap intended to stress the transition band.3.23 Visible RadiationRadiation within the wavelength range from 380 nm to 780 nm is considered to be visible radiation (See “light” in the Glossary).3.24 Visual AngleThe angle subtended by an object or detail at the poi

47、nt of observation is considered to be the visual angle. It usually is measured in radians, milliradians, degrees, or minutes of arc.4.0 EXPOSURE LIMITS4.1 GeneralPersonnel working with or in the vicinity of lamps and lamp systems should not be exposed to levels exceeding the following limits.These c

48、riteria are based on recommendations for Threshold Limit Values (TLVs) of the American Conference of Governmental Industrial Hygienists and recommendations in publications of the International Commission on Non-ionizing Radiation Protection (ICNIRP) (see Bioeffect Datasheet #7). The specific techniq

49、ues of applying these criteria to lamps and lamp systems are given in later standards 4ANSI/IES RP-27.1-15 of this series, i.e., ANSI/IES RP-27.2-00/R2010, and ANSI/IES RP-27.3-07.The limiting aperture dimensions for irradiance mea-surements given in this document are for general application. However, they may not be appropriate for certain specific conditions and devices. Future documents in this series may modify these dimen-sions for those situations.4.2 Ultraviolet Exposure Limits4.2.1 General The ultraviolet exposure limits repre-sent conditions under which it is bel
