Abstract

L'invention porte sur une ampoule électrique à DEL lumineuse à angle large comprenant un bouchon (1), un corps de lampe (2) et une carte de lampe à DEL (3) fixée sur le corps de lampe (2). Le bouchon (1) est connecté au corps de lampe (2). La carte de lampe à DEL (3) possède, connecté de manière recouverte sur celle-ci, un élément réfléchissant (8) qui concentre et réfléchit vers la direction circonférentielle du bouchon (1) une partie d'une lumière émise par la carte de lampe à DEL (3). L'élément réfléchissant (8) est un capot de réflecteur (4) qui va de l'avant vers l'arrière. Le capot de réflecteur (4) possède, agencées dans celui-ci et à l'extérieur de celui-ci, des sources émettrices de lumière à DEL (3-1). Cela résout le problème technique selon lequel une lampe à DEL existante produit une zone morte d'éclairage autour du bouchon, pendant que l'angle d'émission de lumière de l'ampoule est presque identique à l'angle d'émission de lumière d'une lampe à incandescence conventionnelle.
