Abstract
(EN) An apparatus is provided for measuring far-field luminous intensity and color characteristics of a light source that includes a lamp test location for receiving a lamp for testing and a mirror positioned in a fixed light receiving position relative to the lamp test location and positioned in a fixed light transmitting position for reflecting a light beam from the lamp at a predetermined angle relative to the light receiving position. A measurement screen is positioned in a location relative to the mirror to receive the parabolically-condensed light image reflected from the mirror at the predetermined angle and a light detector is positioned to capture a light image reflected from the measurement screen. The light detector is configured to convert the reflected light image on the measurement screen to a digital signal and output the digital signal. A computer calibrated for measuring luminous intensity according to an algorithm processes the digital signal.
(FR) L'invention concerne un appareil étant utilisé pour mesurer l'intensité lumineuse en champ lointain et les caractéristiques de couleur d'une source de lumière qui comprend un emplacement de test de lampe pour recevoir une lampe à tester et un miroir positionné dans une position de réception de lumière fixe par rapport à l'emplacement de test de lampe et positionné dans une position de transmission de lumière fixe pour réfléchir un faisceau de lumière à partir de la lampe selon un angle prédéterminé par rapport à la position de réception de lumière. Un écran de mesure est positionné dans un emplacement par rapport au miroir pour recevoir l'image de lumière condensée de manière parabolique réfléchie par le miroir à l'angle prédéterminé et un détecteur de lumière est positionné pour capturer une image de lumière réfléchie par l'écran de mesure. Le détecteur de lumière est configuré pour convertir l'image de lumière réfléchie sur l'écran de mesure en un signal numérique et délivrer le signal numérique. Un ordinateur étalonné pour mesurer l'intensité lumineuse selon un algorithme traite le signal numérique.
