Abstract

The invention relates to a projection lamp comprising a lamp tube, a lamp panel, a lamp body, a support mechanism and a rotary mechanism. The lamp tube is of a cylindrical structure. A holding cavityis formed in the lamp tube and is provided with a round section and an illuminating opening. The lamp panel is arranged in the lamp tube. The lamp body is arranged on the lamp panel. The support mechanism comprises a support frame and a support shaft. The support shaft is rotationally arranged on the support frame. The support frame is provided with at least one screw hole. The rotary mechanism comprises a drive, a driving shaft and a movable frame. The lamp tube is arranged on the movable frame. The movable frame is movably arranged on the support shaft. The drive is in driving connection with the driving shaft. The driving shaft is movably connected with the movable frame. The drive drives the movable frame to rotate on the support shaft, the illuminating angle of the lamp tube is adjusted automatically, the support shaft can rotate on the support frame, thus the lamp tube can rotate in two or more different dimensions, then the rotation range of the lamp tube is larger, and the projection angle of the projection lamp is large.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a projection lamp. Background technique [0002] The irradiation direction of the projection lamp is relatively concentrated, and its irradiation beam is in the shape of a line. Since the irradiation direction can be adjusted, it is suitable for various occasions that require concentrated lighting. In addition, the projection lamp can also be used for architectural decorative lighting, and can also be used for focused lighting. [0003] The projection direction of the traditional projection lamp usually needs to be manually adjusted, and automatic adjustment cannot be realized, which makes the use of the projection lamp more inconvenient. And even if it can be adjusted automatically, the adjusted projection angle is small and the flexibility is poor, resulting in poor projected lighting effects. Contents of the invention [0004] Based on this, it is necessary to provide a p...
