Title (EN) METHOD AND SYSTEM FOR LUMINANCE CHARACTERIZATION
(FR) PROCEDE ET SYSTEME DE CARACTERISATION DE LA LUMINANCE
Abstract:
(EN) A system for luminance characterization of a luminaire includes a ballast coil and a multi-tap capacitor connected in series with the ballast coil, The multi-tap capacitor has a plurality of tap capacitors integrated into a capacitor housing. A plurality of switches are each coupled to one of the plurality of tap capacitors for selectively coupling the tap capacitors together to produce a multi-tap capacitance corresponding to a configuration of the plurality of switches. A lamp is connected in series with the multi-tap capacitor and the ballast coil. A photometer is located to measure light intensity of the lamp and to produce a lumen output measurement. A memory is used to store a database having a plurality of lumen output measurements, each corresponding to a multi-tap capacitance corresponding to all configurations of the plurality of switches.
(FR) La présente invention concerne un système de caractérisation de la luminance d'un luminaire, comportant une bobine ballast et un condensateur à plusieurs points de prise montés en série. Ce condensateur est en fait constitué d'une pluralité de condensateurs de point de prise réunis dans un logement des condensateurs. Plusieurs commutateurs sont couplés chacun à l'un des différents condensateurs de point de prise de façon à donner un couplage sélectif des condensateurs de point de prise les uns avec les autres de façon à produire une capacitance à plusieurs points de prise correspondant à une configuration de la pluralité de commutateurs. Une lampe est montée en série sur le condensateur à plusieurs points de prise et la bobine de ballast. Un photomètre situé de façon à mesurer l'intensité lumineuse de la lampe, produit en sortie une mesure en lumens. Une mémoire permet de tenir une base de données comportant une pluralité de mesures en lumens correspondant chacune à une capacitance à plusieurs points de prise correspondant à l'ensemble des configurations de la pluralité de commutateurs.
