Abstract

L'invention concerne une lentille en forme de bande (2) destinée à être utilisée dans une lampe à LED et une lampe à grand angle. La lentille comprend un corps. Le corps est en forme de bande. La surface supérieure d'une section longitudinale du corps en forme de bande fait saillie vers l'extérieur pour former une surface de sortie (21). Une surface concave (23) se trouve au centre de la surface de sortie (21). La surface inférieure de la section longitudinale du corps en forme de bande est évidée à une position correspondant à la surface concave (23) pour former une cavité d'incidence (24). La paroi intérieure de la cavité d'incidence (24) fait office de surface d'incidence (22). En équipant une ampoule à LED (4) de la lampe à LED de la lentille en forme de bande, une lumière émise par une source de lumière disposée dans la cavité d'incidence (24) de la lentille peut facilement acquérir un angle de distribution de lumière accrue supérieur à 120 degrés en passant à travers la surface d'incidence (22) et être émise depuis la surface de sortie (21) en saillie où l'angle de distribution de lumière atteint généralement 150 degrés. De plus, la surface concave (23) au centre de la surface de sortie (21) permet à la lumière de la source de lumière qui était initialement concentrée au centre d'être réfractée dans toutes les directions, améliorant ainsi l'angle d'émission de lumière et l'intensité de la lumière périphérique lorsque la source de lumière est munie de la lentille en forme de bande (2) pour la distribution de la lumière.
