ANSI C136.17-2005 (R2010) 2 CONTENTS 1 Scope 2 2 Purpose . 2 3 Physical dimensions 2 4 Materials 2 1 Scope This standard covers the
12、 dimensional features and the materials of refractors of the approximate shape shown in Figures 1 through 3, and as described in ANSI C136.14, American National Standard for Roadway and Area Lighting Equipment Enclosed Side-mounted Luminaires for Horizontal-burning High-intensity Discharge Lamps. 2
13、Purpose This standard provides: a) A description and diagrams of substitute refractors for the original refractor when replacement is necessary. b) The dimensions for a good fit for the refractor at the points of contact, the points of attachment, or both, to the reflector or the housing, or to both
14、 the reflector and the housing. c) Requirements for light distribution acceptable to the user, but not necessarily equal to the original optical system. NOTE The optics package consisting of the lamp, the reflector, and the refractor configuration is unique to the individual luminaire. Replacement o
15、f a single luminaire component will not guarantee the same optical performance. The requirements and figures of this standard will help keep the number of refractors needed on service vehicles to a minimum. 3 Physical dimensions Figures 1 through 3 show the refractors points of contact, points of at
16、tachment, or both, to the reflector, the housing, or both. The dimensions given in these figures are for interchangeability, and other variants satisfying non-dimensioned provisions may be capable of otherwise equivalent performance. 4 Materials Refractors may be made of heat-resistant glass, polyca
17、rbonate, acrylics, or other suitable materials as specified by the user.
