Foreword

This standard is equivalent to using CIE84-1989 "luminous flux measurement method" (in English). This standard is equivalent translation CIE84-1989. For ease of use, this standard made the following editorial changes. The term a) "The technical report" to the "standard"; b) with a decimal point "." instead of as a decimal point "." Appendix A of this standard is an informative annex. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee of electrical lighting (SAC/TC224) centralized. This standard was drafted. National Electric Light Source Quality Supervision and Inspection Center (Beijing), Hangzhou distance Photoelectric Information Co., Ltd., China conformity assessment Set National Accreditation Centre, the National Development and Reform Commission, Guangdong TECHNOLOGY INC, Guangdong Wright Electric Co., Zhongshan City, Australia Keshi Lighting Appliance Co., Ltd. The main drafters of this standard. Hua Shuming, PAN Jian roots, Chen Yanqing, David Lui, Zhou Jianlin, Huangge Ya, Tianchou, Yuan Jian red, huge fertile area, were paid more. This standard was first published.

Introduction

The purpose of this standard is the main methods of flux measurements currently used are discussed. A method in which (according to the illuminance And a luminance distribution calculation) is primarily used by a national standards laboratory, another method (measured using an integrating sphere) is widely used in industrial industry. However, there are individual laboratories of industrial enterprises to adopt a third measurement method. Use goniophotometer measurement light intensity distribution. each One way users are most concerned about their own methods currently used in the field, therefore, it is necessary to make some radical flux measurements Foundation work, so that it can cover these major test methods, and make contact with each other. Flux measuring method

1 Scope

This standard defines the term flux measurements. It relates to the principle of flux measurements, describing the calculation method of the illuminance distribution, product use Methods ball photometer flux and flux methods defined by brightness, light intensity and illuminance measurements.

2.1 Optical Measurement 2.1.1 Luminous flux (Фv; Ф) luminousflux (Фv; Ф) According to the role of radiation on the CIE standard photometric observer, derived from radiant flux Фe light measure. For clear vision, there Φv = Km∫ dΦe (λ) dλ · V (λ) d (λ) (1) Where. dФe (λ)/dλ --- spectral distribution of the radiant flux; V (λ) --- spectral luminous efficiency. Unit. lm. 2.1.2 (Light in the specified direction) luminous intensity (Iv; I) luminousintensity (ofasource, inagivendirection) (Iv; I) From the light source containing the specified direction within a solid angle element dΩ transmission dΦv flux divided by the solid angle element suppliers, namely I = dΦvdΩ (2) Unit. cd = 1m/sr. 2.1.3 (On the surface at a certain point) illuminance (Ev; E) iluminance (atapointofasurface) (Ev; E) DФv flux bin containing the projected point on the surface element divided by the area dA of the business, namely Ev = dΦvdA (3) Unit. lx = lm · m-2. 2.1.4 (In the specified direction on actual or imaginary surface at a given point) luminance (Lv, L) luminance (inagivendirection, ata givenpointofarealorimaginarysurface) (Lv, L) Volume defined by a formula. Lv = dΦvdA · cosθ · dΩ (4) Where. dΦv --- is the result of luminous flux at a given point in the beam element solid angle element dΩ containing the specified direction of propagation; dA --- contains the given point of the beam cross-sectional area; ......
