Title:
PHOTOGRAPHING LED ILLUMINATING LAMP CAPABLE OF PERFORMING DOUBLE-SIDE CONVERSION BETWEEN DIRECT-LIGHTING MODE AND SOFT-LIGHTING MODE
Document Type and Number:
WIPO Patent Application WO/2018/129636
Kind Code:
A1
Abstract:
A photographing LED illuminating lamp capable of performing double-side conversion between a direct-lighting mode and a soft-lighting mode. The photographing LED illuminating lamp comprises a lamp main body (1) and a support (2) disposed on the lamp main body (1). The lamp main body (1) consists of a lamp housing (3), a front LED light-source plate (4), a side LED light-source plate (5), a light guide plate (6), a circuit (7), a power supply (8), a power supply switch (9), and an illumination mode conversion switch. A light-emitting window (13, 14) is disposed on each of a front side surface and a rear side surface of the lamp housing (3), the front LED light-source plate (4) is mounted on one light-emitting window (13), a plurality of LED light sources (17) whose irradiation directions are towards the front is disposed on the front LED light-source plate (4), the light guide plate (6) is mounted on the other light-emitting window (14), the side LED light-source plate (5) is mounted on the side surface of the light guide plate (6), and a plurality of LED light sources (19) whose irradiation directions are towards the side surface (18) of the light guide plate is mounted on the side LED light-source plate (5). The electric components are correspondingly and electrically connected. 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.
