Title
(EN) LIGHTING DEVICE FOR DENTAL TREATMENT
(FR) DISPOSITIF D'ÉCLAIRAGE DESTINÉ À UN TRAITEMENT DENTAIRE

Abstract
(EN)
A lighting device for dental treatment comprises: multiple LED chips; a light guide having multiple branches corresponding to the LED chips, respectively; an optical coating layer formed on the light guide; a fluorescent film layer formed on the optical coating layer; and a lens part formed above the fluorescent film layer, wherein light exiting each of the multiple LED chips is incident to each of the multiple branches of the optical guide, is propagated by total internal reflection through the optical guide, is emitted through the fluorescent film layer, and then is emitted to the outside through the lens part. Each of the multiple branches of the optical guide has a lens shape at the bottom thereof, and the lens shape at the bottom of the branch may be recessed inside the optical guide.

Selon la présente invention, un dispositif d'éclairage destiné à un traitement dentaire comprend : de multiples puces de DEL; un guide de lumière ayant de multiples branches correspondant aux puces de DEL, respectivement; une couche de revêtement optique formée sur le guide de lumière; une couche de film fluorescent formée sur la couche de revêtement optique; et une partie de lentille formée au-dessus de la couche de film fluorescent, la lumière sortant de chacune des multiples puces de DEL étant incidente sur chacune des multiples branches du guide optique, est propagée par réflexion interne totale à travers le guide optique, est émise à travers la couche de film fluorescent, puis est émise à l'extérieur à travers la partie de lentille. Chacune des multiples branches du guide optique a une forme de lentille au fond associé, et la forme de lentille au fond de la branche peut être évidée à l'intérieur du guide optique.
