Embodiment Construction

[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] See figure 1 , the light projection angle adjustment structure of the lamp disclosed in the present invention is mainly a rotating bracket assembly, which is used to connect the lamp body and the electrical box 103 . The rotating bracket assembly includes a rotating shaft 101 and a rotating base 102. The rotating shaft 101 is fixedly connected to the lamp body, and the rotating base 102 is connected to the electrical box 103. The rotating shaft 101 drives the lamp body to rotate 180 degrees relative to the rotating base 102, so that the lamp body can be rotated by 180 degrees. Angle adjustment in the longitudinal circumferential plane; the rotating seat 102 can rotate 60 degrees relative to the electrical box 103, which drives the rotating shaft and then drives the l...

Abstract

The invention relates to a light projection angle adjusting structure of a lamp, comprising a rotating support assembly for connecting an electrical appliance box and a lamp body; the assembly comprises a rotating shaft connected with the lamp body and a rotating seat connected with the electrical appliance box; the rotating shaft and the rotating seat realize the angle adjustment of a lamp body through the longitudinal matching of an annular groove, an annular flange and mutually occlusive trapezoid sawteeth and are fixed through bolts after being adjusted; and the rotating seat and the electrical appliance box realize the angle adjustment and fixation of the lamp body in a horizontal circumferential plane through the horizontal matching of a flange plate, the annular groove and bolts. The structure is also provided with scales for facilitating adjusting process parameters. The structure provided by the invention realizes wide-range adjustment of an angle of the lamp and is flexible and convenient in adjustment mode; and the structure can be firmly fixed after being adjusted, is wide in application range and particularly suitable for angle adjustment of lamps with large sizes and weights.

Description

technical field [0001] The invention relates to an installation structure of a lamp, in particular to a structure for adjusting the light projection angle of the lamp. Background technique [0002] In floodlights, floodlights, advertising lights and other places where the projection angle of the lighting fixture is specified, it is required that the projection angle of the lighting fixture can be easily adjusted in the vertical and horizontal directions and can be fastened and locked at the specified angle. . For lighting fixtures used outdoors at high altitudes, safety must also be satisfied, and the construction and installation personnel's construction time saving and construction convenience must be satisfied. In the adjustment of the light projection angle of the existing lighting fixtures, there are methods such as universal ball swivel and serpentine tube to realize, and there is also a U-shaped iron and screw locking structure to realize. However, the above methods...
