Abstract
(EN)
A lighting apparatus of an embodiment of the present invention comprises: a substrate; a plurality of light sources disposed on the substrate; a resin layer disposed on the substrate and the plurality of light sources; and a first reflective layer disposed on the resin layer. The resin layer comprises an emission surface facing the light sources. The emission surface of the resin layer comprises: a plurality of convex parts respectively facing the light sources; and a plurality of recessed parts respectively disposed between the plurality of convex parts. Concave surfaces respectively disposed on the plurality of recessed parts have a curvature, and the radius of curvature of the concave surfaces can gradually increase toward one direction.
(FR)
Selon un mode de réalisation, la présente invention concerne un module d'éclairage, comprenant : un substrat ; une pluralité de sources de lumière disposées sur le substrat ; une couche de résine disposée sur le substrat et sur la pluralité de sources de lumière ; et une première couche réfléchissante disposée sur la couche de résine. La couche de résine comprend une surface d'émission orientée vers les sources de lumière. La surface d'émission de la couche de résine comprend : une pluralité de parties convexes respectivement orientées vers les sources de lumière ; et une pluralité de parties évidées respectivement disposées entre la pluralité de parties convexes. Des surfaces concaves disposées respectivement sur la pluralité de parties évidées ont une courbure, et le rayon de courbure des surfaces concaves peut progressivement augmenter vers une direction.
