Abstract:
(EN) A lighting module disclosed in an embodiment comprises: a circuit board having a plurality of first recesses; a light-emitting element arranged on the circuit board; and an optical lens which has a plurality of protrusion portions, and which is arranged on the light-emitting element. The circuit board comprises an absorbing layer arranged on the periphery of each of the first recesses. The optical lens comprises a bottom surface, a second recess having an incident surface at the center area of the bottom surface, and a first emission surface having a curved surface. The protrusion portions protrude from the bottom surface toward the circuit board. The second recess is arranged on the light-emitting element. Parts of the protrusion portions are arranged in the first recesses. The circuit board comprises an absorbing layer provided on the upper portion thereof so as to surround at least one of the plurality of protrusion portions. The absorbing layer surrounding the protrusion portion is arranged in an area corresponding to 2.5 times the radius of the protrusion portion or less from the center of the protrusion portion, and the center of the protrusion portion may be arranged in a range corresponding to 0.3 to 0.95 times the radius of the bottom surface from the center of the bottom of the second recess.
(FR) La présente invention concerne, selon un mode de réalisation, un module d'éclairage comprenant : une carte de circuit imprimé comprenant une pluralité de premiers évidements; un élément électroluminescent disposé sur la carte de circuit imprimé; et une lentille optique présentant une pluralité de parties saillantes, placée sur l'élément électroluminescent. La carte de circuit imprimé comprend une couche absorbante disposée sur la périphérie de chacun des premiers évidements. La lentille optique comprend une surface inférieure, un second évidement présentant une surface incidente au niveau de la zone centrale de la surface inférieure, et une première surface d'émission présentant une surface incurvée. Les parties saillantes font saillie à partir de la surface inférieure en direction de la carte de circuit imprimé. Le second évidement est disposé sur l'élément électroluminescent. Des portions des parties saillantes sont disposées dans les premiers évidements. Une couche absorbante est disposée sur la partie supérieure de la carte de circuit imprimé de façon à entourer au moins une partie saillante de la pluralité de parties saillantes. La couche absorbante entourant la partie saillante est disposée dans une zone correspondant à au plus 2,5 fois le rayon de la partie saillante depuis son centre, et le centre de la partie saillante peut être disposé dans une plage correspondant à 0,3 à 0,95 fois le rayon de la surface inférieure à partir du centre du fond du second évidement.
