Abstract
(EN)
According to the present invention, a method for generating lens shape information for a point light source comprises the steps of: receiving an input of information on the light distribution properties of a point light source, information on the light distribution properties of a target, and information on lens shape settings; generating lens shape information for a semispherical lens defining a cylindrical opening, in accordance with the lens shape settings information; dividing a light exit angle of the point light source into a first light exit angle range that is incident on a top surface of the opening and a second light exit angle range that is incident on a side surface of the opening, in accordance with the height of the opening of the lens shape information; outputting a quantity of light for the first and second light exit angle ranges, respectively, in accordance with the information on the light distribution properties of the point light source; dividing the information on the light distribution properties of the target into first and second information on the light distribution properties of the target in accordance with a ratio of the light output quantities, such that, when divided, the exit angles constitute the overall exit angle of the lens, and the quantities of light are equal; generating shape information for the top surface of the opening such that light incident through the top surface of the opening is refracted in correspondence with the first light distribution properties of the target; and generating shape information for an outer side surface of the lens such that light incident through the side surface of the opening is refracted in correspondence with the second light distribution properties of the target.

Selon cette invention, un procédé de génération d'informations relatives à une configuration de lentille pour une source d'éclairage ponctuel consiste à recevoir une entrée d'informations concernant les propriétés de distribution de lumière d'une source d'éclairage ponctuel, des informations concernant les propriétés de distribution de lumière sur une cible et des informations concernant des réglages de configuration de lentille; générer des informations de configuration de lentille pour une lentille semi-sphérique définissant une ouverture cylindrique en fonction des informations de réglage de configuration de lentille; diviser un angle de sortie de lumière de la source d'éclairage ponctuel en une première plage d'angle de sortie de lumière qui est incidente sur une surface supérieure de l'ouverture et une seconde plage d'angle de sortie de lumière qui est incidente sur une surface latérale de l'ouverture en fonction de la hauteur de l'ouverture et des informations de configuration de lentille; émettre une quantité de lumière pour les première et seconde plages d'angle de sortie de lumière, respectivement, en fonction des informations concernant les propriétés de distribution de lumière de la source d'éclairage ponctuel; diviser les informations concernant les propriétés de distribution de lumière sur la cible en des première et seconde informations concernant les propriétés de distribution de lumière sur la cible en fonction d'un rapport des quantités d'émission de lumière de telle sorte que, une fois divisés, les angles de sortie constituent l'angle de sortie global de la lentille, et que les quantités de lumière soient égales; générer des informations relatives à la configuration pour la surface supérieure de l'ouverture de sorte que la lumière incidente dans la surface supérieure de l'ouverture soit réfractée en correspondance avec les premières propriétés de distribution de lumière sur la cible; et générer des informations relatives à la configuration pour une surface latérale externe de la lentille de telle sorte que la lumière incidente dans la surface latérale de l'ouverture soit réfractée en correspondance avec les secondes propriétés de distribution de lumière sur la cible.
