FOREWORD. The primary objective of this Technical Report is to r
32、ecommend the adop- tion of test procedures which will provide acceptable results in measur- ing and reporting the photometric characteristics of floodlights. The recommendations are intended to provide a basis for uniform national standards, and to give guidance to industrial photometric laboratorie
33、s in the selection of test apparatus, in the conduct of tests and in the presentation of floodlight performance data. This Technical Report is not an officially agreed C.I.E. Recommendation and any recommendations in this report are advisory and not mandatory. 2. SCOPE. 2.1 These recommendations are
34、 intended to cover the photometry of floodlights used for interior and exterior lighting purposes and equipped with in- candescent or discharge (including tubular fluorescent) electric lamps, or with reflector lamps. Similar techniques may be used for gas or oil operated floodlights. The recommendat
35、ions relate to visually steady light and not to a flashing light, 2.2 The photometric techniques recommended do not include the photometry of projectors for signalling purposes, road lighting lanterns, vehicle head- lights (some of which are covered by other documents) nor “image-forming“ optical de
36、vices, although similar techniques may well be used fur the photometry of such devices. In some cases recommendations may be prepa- red by other committees. 2.3 Light beams, in which the angle between the peak and the one-half peak intensity direction is less than 2“ (i.e. 2 x 2“, or 4“ to one-half
37、peak divergence for a symmetrical beam), require special methods of photometry which are not included. Information on such measurements is available in the literature, see for example : (a) “Photometry of Projected Light“ by J.M. Waldram, (b) “Symposium on Searchlights“ published by The Illuminating

42、EFINITIONS The definitions 3.1, 3.2, 3.3 and 3.4 may only be used for distributions with a continuous reduction in luminous intensity at increasing angles of divergence from a single maximum.

The luminous intensity distribution through a single plane ab illustrated in rectangular cartesian co-ordinates in fig 1 has a half peak side angle of Bi in half plane a and 62 in half plane b. The one half peak divergence
