Abstract
(EN)
A photographing LED illuminating lamp capable of rotationally converting between a direct-lighting mode and a soft-lighting mode comprises a lamp holder (1), a light-emitting main body (2), and a support (3). The bottom of the light-emitting main body (2) is in rotational fit with the top of the lamp holder (1). The support (3) is disposed on the bottom of the lamp holder (1). The light-emitting main body (2) consists of a main body housing (4), a front LED light-source plate (5), a side LED light-source plate (6), and a light guide plate (7). A light-emitting window (10, 11) is disposed on each of a front side surface (8) and a rear side surface (9) of the main body housing (4). The front LED light-source plate (5) is mounted on one light-emitting window (10), and a plurality of LED light sources (12) whose irradiation directions are towards the front is disposed on the front LED light-source plate (5). The light guide plate (7) is mounted on the other light-emitting window (11). The side LED light-source plate (6) is mounted on the outer side of the light guide plate (7). A plurality of LED light sources (14) whose irradiation directions are towards the side surface (13) of the light guide plate is mounted on the side LED light-source plate (6). The problem of limitations of illuminating brightness due to certain loss of illuminating brightness in both direct-lighting illumination and soft-lighting illumination existing in the similar prior art is resolved.

L'invention concerne une lampe d'éclairage à DEL de photographie permettant une conversion en rotation entre un mode d'éclairage direct et un mode d'éclairage indirect comprenant un porte-lampe (1), un corps principal émetteur de lumière (2) et un support (3). Le fond du corps principal émetteur de lumière (2) est en ajustement rotatif avec le sommet du porte-lampe (1). Le support (3) est disposé sur le fond du porte-lampe (1). Le corps principal émetteur de lumière (2) est composé d'un boîtier de corps principal (4), d'une plaque de source de lumière à DEL avant (5), d'une plaque de source de lumière à DEL latérale (6) et d'une plaque de guidage de lumière (7). Une fenêtre émettrice de lumière (10, 11) est disposée sur chacune d'une surface latérale avant (8) et d'une surface latérale arrière (9) du boîtier de corps principal (4). La plaque de source de lumière à DEL avant (5) est montée sur une fenêtre d'émission de lumière (10), et une pluralité de sources de lumière à DEL (12) dont les directions d'exposition à un rayonnement sont vers l'avant est disposée sur la plaque de source de lumière à DEL avant (5). La plaque de guidage de lumière (7) est montée sur l'autre fenêtre émettrice de lumière (11). La plaque de source de lumière à DEL latérale (6) est montée sur le côté externe de la plaque de guidage de lumière (7). Une pluralité de sources de lumière à DEL (14) dont les directions d'exposition à un rayonnement sont vers la surface latérale (13) de la plaque de guidage de lumière est montée sur la plaque de source de lumière à DEL latérale (6). Le problème de limitations de luminosité d'éclairage en raison d'une certaine perte de luminosité d'éclairage à la fois dans un mode d'éclairage direct et un mode d'éclairage indirect existant dans l'état de la technique similaire est résolu.
