Abstract

L'invention concerne une lampe d'éclairage à DEL de photographie pouvant convertir par rotation entre un mode d'éclairage direct et un mode d'éclairage tamisé qui comprend un porte-lampe (1), un corps principal (2) électroluminescent, et un support (3). Le corps principal (2) électroluminescent présente un emboîtement permettant la rotation dans le porte-lampe (1). Le corps principal (2) électroluminescent est constitué d'un logement (4) de corps principal, d'une plaque de sources (5) de lumière à DEL comportant une lentille convexe, d'une plaque de sources (6) de lumière à DEL ne comportant pas de lentille convexe, et d'un diffuseur (7). Une fenêtre électroluminescente (10, 11) est disposée sur chaque surface parmi une surface avant (8) et une surface arrière (9) du logement (4) de corps principal. La plaque de sources (5) de lumière à DEL comportant une lentille convexe est montée sur une fenêtre électroluminescente (10), et une pluralité de sources de lumière à DEL (12) qui comportent des lentilles convexes et dont les directions de rayonnement sont dirigées vers l'avant est disposée sur la plaque de sources (5) de lumière à DEL comportant une lentille convexe. Le diffuseur (7) est monté sur l'autre fenêtre électroluminescente (11). La plaque de sources (6) de lumière à DEL ne comportant pas de lentille convexe est montée derrière la plaque de guide (7) de lumière. Une pluralité de sources (13) de lumière à DEL qui ne comportent pas de lentille convexe et dont les directions de rayonnement sont dirigées vers l'arrière de la plaque de guide (7) de lumière est montée sur la plaque de sources de lumière (6) à DEL ne comportant pas de lentille convexe. Une carte de circuit imprimé (14), une alimentation électrique (15), un commutateur (16) d'alimentation électrique et un commutateur de conversion de mode sont disposés sur le porte-lampe (1) ou sur le corps principal (2) électroluminescent. La lampe d'éclairage résout le problème de limitations de la luminosité d'éclairage en raison d'une certaine perte de luminosité d'éclairage tant dans l'éclairage direct que dans l'éclairage tamisé.
