24、bility to TC 34. The objective of this introduction is to help the reader to understand which terms are included and to have an understanding of the LED product overview. Compared with IEC TS 62504, the main changes are as follows. 0.2 Terms to include General lighting terms in IEC 60050-845:1987, I

25、nternational Electrotechnical Vocabulary that have not been modified will not be included in this standard. Alignment with CIE is done. IEC will be the reference for products and related equipment and CIE for lighting terminology. Alignment with ANSI RP16-10, Chapter 6.8 was also considered. The ter

26、ms included are as far as possible used in LED standards and manufacturers literature., Process to update IEC 60050-845:1987, the International Electrotechnical Vocabulary for definitions that will be considered as relevant is underway in IEC TC34. 0.3 Alphabetic sequence In order to find the term i

27、n a logical sequence, we have grouped similar terms of a product, example: LED lamp integrated LED lamp , non-integrated LED lamp . For each term, reference is made to the relevant standard if appropriate. 0.4 LED product tree: The sequence from the first component, the LED die up to the LED luminai

28、re is drawn. The term LED does not represent a product, so no technical data can be linked to the term LED. BS EN 62504:2014 6 IEC 62504:2014 IEC 2014 GENERAL LIGHTING LIGHT EMITTING DIODE (LED) PRODUCTS AND RELATED EQUIPMENT TERMS AND DEFINITIONS 1 Scope This International Standard IEC 62504 is of

29、assistance in the common understanding of terms and definitions, relevant for general lighting with LED technology. The terms included are those already available in IEC LED standards or used in manufacturers literature. This standard provides descriptive terms (like “LED light sources”) and measura

30、ble terms when modified from IEC 60050-845 (like “colour rendering index”). NOTE Annex A gives overviews of LED package design and systems composed of LED light sources and controlgear. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document a

32、port 127:2007, Measurement of LEDs 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60050-845, with the exception of those modified below, and the following apply. 3.1 ageing preconditioning period of the LED light source before initial values are tak

33、en 3.2 angular subtense angle subtended by an apparent source as viewed from a point in space Note 1 to entry: Angular subtense is expressed in radians (rad). Note 2 to entry: The angle extension is determined by the observation distance, but at no distance smaller than the minimum distance of accom

34、modation of the eye. Note 3 to entry: The location and angular subtense of the apparent source depends on the viewing position in the beam. Note 4 to entry: The angular subtense of an apparent source is only applicable in the wavelength range from 380 nm to1 400 nm. Note 5 to entry: IEC TR 62778 giv

35、es additional information with regards to beam divergence. BS EN 62504:2014IEC 62504:2014 IEC 2014 7 SOURCE: IEC 60825-1, 3.7, modified Notes 1, 2 and 5 to entry are added and in the note 4 to entry the value of the wavelength range has been changed from 400 nm to 1 400 nm to 380 nm to 1 400 nm; IEC

36、 62471, 3.2, modified. 3.3 apparent source for a given evaluation location of the retinal hazard, the real or virtual object that forms the smallest possible retinal image (considering the accommodation range of the human eye) Note 1 to entry: The accommodation range of the eye is assumed to be vari

37、able from 100 mm to infinity. The location of the apparent source for a given viewing position in the beam is that location to which the eye accommodates to produce the most hazardous retinal irradiance condition. Note 2 to entry: This definition is used to determine, for a given evaluation position

38、, the location of the apparent origin of laser radiation in the wavelength range of 380 nm to 1 400 nm. In the limit of vanishing divergence, i.e. in the case of a well collimated beam, the location of the apparent source goes to infinity. SOURCE: IEC 60825-1, 3.10, modified In the note 2 to entry t

39、he value of the wavelength range is changed from 400 nm to 1 400 nm to 380 nm to 1 400 nm. 3.4 beam angle angle between two imaginary lines in a plane through the optical beam axis, such that these lines pass through the centre of the front face of the lamp and through points at which the luminous i

40、ntensity is 50 % of the centre beam intensity Note 1 to entry: Beam angle is expressed in degrees ( ). Note 2 to entry: This angle is a full angle measure, not a half angle measure. SOURCE: IEC TR 61341, 2.4, modified, The notes to entry are added. 3.5 bin restricted range of LED performance charact

41、eristics used to delimit a subset of LED dies or LED packages near a nominal LED performance as identified by chromaticity, photometric, radiometric and/or electrical characteristics 3.6 controlgear 3.6.1 controlgear for LED module LED controlgear unit inserted between the electrical supply and one

42、or more LED modules, which serves to supply the LED module(s) with its (their) rated voltage or rated current, and may consist of one or more separate components and may include means for dimming, correcting the power factor and suppressing radio interference, and further control functions Note 1 to

43、 entry: The controlgear consists of a power supply and a control unit. Note 2 to entry: The controlgear may be partly or totally integrated in the LED module. Note 3 to entry: When no confusion is expected like when used in a LED standard for example, “controlgear” may also be used. Both terms “cont

44、rolgear” or “control gear” are acceptable. SOURCE: IEC 61347-2-13, 3.1, modified The word electronic is deleted from the term and the words “further control functions” and the notes to entry are added. 3.6.2 power supply of the controlgear electronic device, being part of the controlgear, capable of

45、 controlling current, voltage or power within design limits, containing no additional LED control capabilities BS EN 62504:2014 8 IEC 62504:2014 IEC 2014 Note 1 to entry: For LEDsi modules, the power supply of the controlgear is separate from the LED module on a distant location. Note 2 to entry: Th

46、e energy source of a power supply can be either a battery or the electrical supply system. 3.6.3 control unit of the controlgear electronic device, being part of the controlgear, responsible for controlling the electrical energy to the LED light sources as well as colour mixing, response to deprecia

47、ting luminous flux and further performance features Note 1 to entry: In LEDsi modules, the control unit of the controlgear is on board of the LED module and separate from the power supply of the controlgear. 3.7 dominant wavelength dwavelength of the monochromatic stimulus that, when additively mixe

48、d in suitable proportions with the specified achromatic stimulus, matches the colour stimulus considered in the CIE 1931 x,y chromaticity diagram Note 1 to entry: Dominant wavelength is expressed in nanometres (nm). Note 2 to entry: In the case of purple stimuli, the dominant wavelength is replaced

49、by the complementary wavelength. Note 3 to entry: For characterising LED light sources the reference achromatic stimulus should be illuminant E which has the chromaticity coordinates xE = 0,3333, yE= 0,3333. Note 4 to entry: A value for dominant wavelength should only be stated for LED light sources emitting coloured light. For LED light sources emitting white light no meaningful value for dominant wavelength can be given. Note 5 to entry: Figure 12 in
