Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "up," "down," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 2 and 3, a lifting lamp comprises a housing 10, a wire 20 and a light source 30, wherein a wire winding mechanism 40 is arranged inside the housing 10;

the winding mechanism 40 comprises a fixing plate 41, the fixing plate 41 is fixedly connected with the housing 10, a rotating shaft 47 is arranged in the middle of the fixing plate 41, one end of the rotating shaft 47 is rotatably connected with the fixing plate 41, and a winding disc 44 is arranged at the other end; a motor 42 is arranged on the lower side of the fixed plate 41, and a belt 45 is arranged between the rotating shaft of the motor 42 and a rotating shaft 47;

one end of the wire 20 is wound on the wire spool 44, and the other end is connected with the light source 30;

the fixed plate 41 is provided with a first sensor 50 and a second sensor 60, and the second sensor 60 is close to the rotating shaft of the motor 42;

the fixed plate 41 is provided with a controller 48, and the motor 42, the first sensor 50 and the second sensor 60 are respectively electrically connected with the controller 48.

When the light source 30 needs to be lifted, the controller 48 makes the motor 42 rotate clockwise, the belt 45 drives the rotating shaft 47 and the wire spool 44 to rotate, and the wire 20 is wound on the wire spool 44, so that the light source 30 is close to the housing 10, and the purpose of lifting the light source 30 is achieved; conversely, the motor 42 rotates counterclockwise to achieve the goal of lowering the light source 30.

Further, as shown in fig. 2 and 3, a position limiting plate 46 fixedly connected to the rotating shaft 47 is disposed between the fixing plate 41 and the wire spool 44, and eight positioning holes coaxially and circumferentially distributed with the rotating shaft 47 are disposed on the position limiting plate 46; a locking device 43 is arranged on the fixing plate 41 at a position corresponding to one of the positioning holes, and the locking device 43 comprises a clamping tenon which can be inserted into or separated from the positioning hole; the locking device 43 is electrically connected to the controller 48.

The clamping falcon of the locker 43 is separated from the positioning hole during the lifting of the light source 30, and the clamping falcon of the locker 43 is inserted into the positioning hole after the light source 30 is lifted to a proper position, thereby preventing the light source 30 from being accidentally lowered.

Further, the first sensor 50 is a hall sensor, and the second sensor 60 is an opto-coupler sensor.

The second sensor 60 is used for detecting parameters such as the rotation speed and angle of the motor 42, and the first sensor 50 is used for determining the winding amount of the wire 20 in the wire spool 44.

Further, as shown in fig. 2 and 3, a baffle 70 is disposed on the outer side of the wire spool 44.
