Abstract

L'invention concerne une lentille de distribution de lumière, présentant une surface supérieure en forme de selle, constituée de multiples segments de surfaces lisses incurvées reliées et formant une surface irrégulière incurvée, et une surface irrégulière incurvée est formée entre deux surfaces lisses incurvées voisines dans les multiples segments des surfaces lisses incurvées ; un renfoncement est ménagé au centre de la partie inférieure de la lentille de distribution de lumière afin de placer une source de lumière à DEL. L'invention concerne également un module de lentille de distribution de lumière comportant la lentille de distribution de lumière, et une lampe à DEL à économie d'énergie. La lentille de distribution de lumière améliore l'uniformité des mouchetures émergentes, améliorant l'effet d'éclairage, et elle est ainsi susceptible d'être largement utilisée dans le secteur de l'éclairage.
