Document Type and Number:
WIPO Patent Application WO/2018/129637
Kind Code:
A1
Abstract:
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 light-emitting main body (2) is in rotational fit with the lamp holder (1). The light-emitting main body (2) consists of a main body housing (4), an LED light-source plate (5) provided with a convex lens, an LED light-source plate (6) not provided with a convex lens, and a diffuser (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 LED light-source plate (5) provided with a convex lens is mounted on one light-emitting window (10), and a plurality of LED light sources (12) that are provided with convex lenses and whose irradiation directions are towards the front is disposed on the LED light-source plate (5) provided with a convex lens. The diffuser (7) is mounted on the other light-emitting window (11). The LED light-source plate (6) not provided with a convex lens is mounted behind the light guide plate (7). A plurality of LED light sources (13) that are not provided with convex lenses and whose irradiation directions are towards the back of the light guide plate (7) is mounted on the LED light-source plate (6) not provided with a convex lens. A circuit board (14), a power supply (15), a power supply switch (16) and an illumination mode conversion switch are disposed on the lamp holder (1) or the light-emitting main body (2). The illuminating lamp resolves the problem of limitations of illuminating brightness due to certain loss of illuminating brightness in both direct-lighting illumination and soft-lighting illumination.
