Variable-direction LED lighting lamp device

Abstract

Disclosed is a variable-direction LED lighting lamp device. The variable-direction LED lighting lamp device comprise a frame and an LED lighting lamp device body. A running trough and an installing and fixing trough are formed in the frame, wherein an end opening of the running trough is upward, and an end opening of the installing and fixing trough faces the running trough. A running disc is installed in the running trough through a bearing in a running mode. A middle trough is formed in the middle of the running disc. A lifting arm is movably installed in the middle trough. An inner spiral hole with a downward end opening is formed in the lifting arm. A lifting spiral rod is installed in the inner spiral hole in a threaded and matched mode. A running middle shaft is installed at the lower end of the middle trough through a bearing in a running mode. The upper end of the running middle shaft is fixedly connected with the lifting spiral rod. The lower end of the running middle shaft stretches into the installing and fixing trough and is fixedly provided with an upper running toothed wheel. An inner tooth ring is fixedly installed at the bottom end of the installing and fixing trough. The running disc is further internally provided with a longitudinal edge movable cavity which stretches out of the longitudinal edge. A movable frame is further movably installed in the longitudinal edge movable cavity. A lifting electric rotating machine is fixedly installed in the movable frame.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a direction-changing LED lighting device. Background technique [0002] With the development of the times, there are many kinds of LED lighting lamps and their uses are very wide. The structure of the existing LED lighting lamps is usually fixed, so the angle of light irradiation is fixed. When it is necessary to adjust the direction of the irradiation , the operation is troublesome, such as bridge night scene, grass spotlight, etc., by changing its irradiation direction, it can bring different illumination effects, and the operation of the light can change people's visual effects. The existing bridge night scene lights and grass spotlights are usually It is fixed and it is difficult to achieve better visual effects. Contents of the invention [0003] The object of the present invention is to provide a direction-changing LED lighting device and its use method, which can overc...
