21、le to serve a facility that may operate 24 h a day, 365 days a year. Two major factors govern adequate illumination in each area and for each activity in the health care facility: (a) the quality of the illumination, ie, the colour rendition and the distribution of luminance; and (b) the quantity of

22、 illumination. It is recognized that age influences the suitability of lighting levels in the performance of tasks. The mean age within Canadian health care facilities is rising, resulting in the need for higher lighting levels. The lighting levels in this Standard have been specified based on a min

23、imum user population age of 55. It is recognized that this may lead to an increase in energy consumption. Where appropriate and with proper consultation, the lighting levels may be modified to suit individual needs. This Standard has been written for as wide an audience as possible, including design

24、ers, consultants, hospital administration, and engineering departments. Every effort has been made not to restrict the application of new technologies within the health care facility. However, proper evaluation of new technologies prior to implementation is needed to ensure overall safety. This Stan

25、dard is not intended to be used as a textbook on lighting. The IES Lighting Handbook and other similar material, courses, and seminars serve these purposes. To help establish the levels of illumination to be included in this Standard, the energy conservation measures in many health care facilities w

26、ere examined. A survey of these health care facilities produced data which, together with the data from the Illuminating Engineering Society of North America (IESNA), illumination societies in the United Kingdom, Sweden, and Germany, and German and Australian standards, have formed the basis for the

27、 levels of illumination recommended in this Standard. The Alberta Government publication Mechanical and Electrkal Design Guidelines10r Health Care Facilities, the Ontario Ministry of Health publication Illumination Systems in Hospitals, and the IESNA publication lI1umination Systems in Health Care F

28、acilities were also referred to and contributed to the preparation of the first edition of this Standard. This Standard was prepared by the Subcommittee on Illumination in Health Care Facilities, under the jurisdiction of the Technical Committee on Health Care Facility Engineering and Physical Plant

29、 and the Strategic Steering Committee on Health Care Technology. The Standard was formally approved by these Committees. March 7998 Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows. (2) Although the intended primary application of this Standard is sta

30、ted in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. (3) This publication was developed by consensus, which is defined by the (SA Regulations Governing Standardization as “substantial agreemen

31、t reached by concerned interests. Consensus includes an attempt to remove all objections and implies much more than the concept of a simple majority, but not necessarily unanimity“. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in

32、full agreement with a/l clauses of the publication. x March 1998 Illumination Systems in Health Care Facilities (4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (5) All enquiries regarding this Standard, including

33、requests for interpretation should be addressed to Canadian Standards Association Standards Development, 178 Rexdale Boulevard, Etobicoke, Ontario M9W 1 R3. Requests for interpretation should (a) define the problem, making reference to the specific clause, and, where appropriate, include an illustra

34、tive sketch; (b) provide an explanation of circumstances surrounding the actual field condition; and (c) be phrased where possible to permit a specific “yes“ or “no“ answer. Committee Interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are

36、tandard provides specific design criteria for illumination systems in various locations within a health care facility. Note: Lighting is both an art and a science. The basic technical criteria given in this Standard are not intended to inhibit creative design, but rather to ensure that minimum requi

37、rements are met. 1.2 This Standard deals with (a) illumination sources; (b) luminaires; (c) illumination levels (see Tables 1, 2, and 3); and (d) guidelines for specific areas and tasks. 1.3 This Standard does not deal with (a) therapeutic illumination devices (eg, phototherapy lamps); and (b) speci

38、al purpose devices such as UV sources for sterilization. 1.4 This Standard addresses requirements for illumination systems. However, it is not meant to remove the need for consultation with users regarding specific or unusual requirements. 1.5 The requirements in this Standard are intended to be sub

39、ordinate to applicable Provincial, Federal, or local regulatory authorities. 1.6 In this Standard, “shall“ indicates a mandatory requirement; “should“ indicates a recommendation, or that which is advised but not mandatory. Notes accompanying clauses do not include mandatory or alternative requiremen

40、ts. The purpose of a Note accompanying a clause is to separate from the text explanatory or informative material that is not properly a part of the Standard. Notes to figures and tables are considered to be part of the figure or table and are written as mandatory requirements. 2. Definitions 2.1 The

41、 following definitions apply in this Standard: March 1998 1 Z3 7 7.5-98 Note: Different terms may be used to refer to the same illuminating engineering parameters (eg, luminance for brightness, illuminance for illumination). In the following list of definitions, the approved terms are defined and cr

42、oss-referenced to older terms that are still in limited use. Adaptation - the process by which the retina becomes accustomed to more or less light, or light of a different colour. Ambient lighting - the general illumination throughout an area. Ballast - a device used with fluorescent and high intens

43、ity discharge (HID) lamps to obtain the necessary circuit conditions (voltage, current, frequency, and wave form) for starting and operating. It limits the flow of current through the lamp. Brightness - see luminance and Subjective brightness. Candela, cd (formerly candle) - the SI unit of luminous

44、intensity. Candlepower, cp - the luminous intensity of a light source expressed in candelas. For the defined relationships between units, see Illuminance. Colour rendering - the general expression for the effect of a light source on the colour appearance of an object in conscious or subconscious com

45、parison with its colour appearance under a reference light source. Colour rendering index (of a light source), CRI- the measure of the degree to which the perceived colour of an object illuminated by the source conforms to that of the same object illuminated by a reference light source of comparable

46、 colour temperature. Colour temperature - the temperature of the black body radiator which emits radiation of the same chromaticity as the radiation considered. The unit of measurement is the kelvin (K). Contrast (luminance contrast) - the relationship between the luminances of an object or task det

47、ail and its immediate background. Diffuser - a device that redirects or scatters light from a source, primarily by the process of diffuse transmission. Diffuse reflection - the process by which incident flux is redirected over a range of angles. Direct glare - glare resulting from excessive luminanc

48、e and insufficiently shielded light sources within the field of view. Downllght - a luminaire that directs all the luminous flux down. It is usually recessed, though it may be surface-mounted or suspended. Efficacy, lumens per watt - the quotient of the total of emitted luminous flux from the lamp d

49、ivided by the electrical power (watts) input to the lamp. Equivalent Sphere Illumination (ESI) - the level of sphere illumination that would produce task visibility equivalent to that produced by a specific lighting environment. ESI is a means of measuring and predicting illumination quality as it relates to veiling reflections. In Canada, the unit in common use is the ESI foot candle. 2 March 7998 Illumination Systems in Health Care Facilities Examination lights -luminaires used for minor medical procedures outside the operating room.
