Title:
PHOTOGRAPHING LED ILLUMINATING LAMP CAPABLE OF ROTATIONALLY CONVERTING BETWEEN DIRECT-LIGHTING MODE AND SOFT-LIGHTING MODE
Document Type and Number:
WIPO Patent Application WO/2018/129635
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 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.
