Abstract
(EN)
A white light source system being an illumination light source for a variety of target objects, such as exhibits in an art gallery, that required high color-rendering properties similar to natural light and being capable of: taking into consideration regional and time differences and reproducing sunlight shone on to earth; and being capable of radiating white light having reduced ultraviolet or blue light-emission components that may have ain and-verse impart on paintings, etc. The white light source system uses at least four types of white light sources comprising a combination of ultraviolet and violet light-emitting LEDs and phosphors. As a result of adjusting the types of phosphor material used and the mixing proportions for the white light sources, the white light source system continuously reproduces daily changes in sunlight for a specified, season and a specified region and reproduces a white light that takes safety issues into consideration by improving the device structure.

La présente invention concerne un système à source lumineuse blanche qui est une source lumineuse d'éclairage pour une variété d'objets cibles, tels que des pièces dans une galerie d'art, qui nécessitent des propriétés de rendu de couleurs élevées similaires à la lumière naturelle et qui est capable : de prendre en considération des différences régionales et temporelles et de reproduire la lumière du soleil dirigée vers la terre ; et est capable de faire rayonner de la lumière blanche qui présente des composants réduits d'émission de lumière ultraviolette ou de lumière bleue qui peuvent avoir un impact défavorable sur des peintures, etc Le système à source lumineuse blanche utilise au moins quatre types de sources lumineuses blanches qui comprennent une combinaison de LED qui émettent de la lumière ultraviolette et violette et de phosphores. En conséquence de l'ajustement des types de matériau phosphore utilisé et des proportions de mélange pour les sources lumineuses blanches, le système à source lumineuse blanche reproduit en continu des changements quotidiens de lumière solaire pour une saison spécifiée et pour une région spécifiée et reproduit une lumière blanche qui prend en considération des problèmes de sécurité en améliorant la structure de dispositif.
