Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a movable light-blocking lamp, comprising a lamp housing 1, an upper light-blocking blade assembly 2, and a lower light-blocking blade assembly 3. The lamp housing 1 has a light outlet 11 on its front end face. The length of the upper end face 12 of the lamp housing 1 is less than the length of the lower end face 13 of the lamp housing 1. The upper light-blocking blade assembly 2 includes an upper light-blocking blade 21 and an upper reduction motor 22. The upper reduction motor 22 is disposed on the upper part of the lamp housing 1 and is connected to the upper light-blocking blade 21, driving the upper light-blocking blade 21 to cover the light outlet 11. The lower light-blocking blade assembly 3 includes a lower light-blocking blade 31 and a lower reduction motor 32. The lower reduction motor 32 is disposed on the lower part of the lamp housing 1 and is connected to the lower light-blocking blade 31, driving the lower light-blocking blade 31 to cover the upper light-blocking blade 21.

[0020] This invention allows for flexible adjustment of the light output effect by arbitrarily adjusting the angle of the upper light-blocking blade 21 using the upper geared motor 22 and the lower geared motor 32 using the lower light-blocking blade 31. Different light output angles are formed between the upper and lower light-blocking blades 21 and 31. When the upper and lower light-blocking blades 21 and 31 are fully closed, the upper light-blocking blade 21 covers the light output port 11 of the lamp housing 1, and the lower light-blocking blade covers the upper light-blocking blade 21, further ensuring the light-blocking effect. Temporary light-blocking can be achieved without power interruption, and it is convenient for storage and transportation. Furthermore, the upper and lower geared motors 22 and 32 can fix the positions of the upper and lower light-blocking blades 21 and 31 with the help of their own gearboxes. Even after power failure, the upper and lower light-blocking blades 21 and 31 can remain in their pre-power-loss positions, reducing the reset time of the upper and lower light-blocking blades 21 and 31.

[0021] For example, the upper end face 12 of the lamp housing 1 is parallel to the lower end face 13 of the lamp housing 1, so that the upper light-blocking blade 21 and the lower light-blocking blade 31 can be better overlapped with the lamp housing 1, improving the light-blocking effect after the light-blocking blades are fully closed; the front end face of the lamp housing 1 is inclined outward from top to bottom, further improving the compactness of the upper light-blocking blade 21 and the lower light-blocking blade 31 after overlap.

[0022] For example, the upper part of the lamp housing 1 is provided with an upper mounting groove 14, the upper reduction motor 22 is disposed at one end of the upper mounting groove 14, the output end of the upper reduction motor 22 is connected to an upper connecting plate 23, the end of the upper connecting plate 23 is rotatably connected to the other end of the upper mounting groove 14, and the upper light-blocking blade 21 is connected to the upper connecting plate 23, making the upper light-blocking blade assembly 2 and the lamp housing 1 more compact in structure, reducing the space occupied, and making the rotation of the upper light-blocking blade 21 more stable.

[0023] For example, the lower part of the lamp housing 1 is provided with a lower mounting groove 15, the lower reduction motor 32 is disposed at one end of the lower mounting groove 15, the output end of the lower reduction motor 32 is connected to a lower connecting plate 33, the end of the lower connecting plate 33 is rotatably connected to the other end of the lower mounting groove 15, and the lower light-blocking blade 31 is connected to the lower connecting plate 33, making the structure of the lower light-blocking blade assembly 3 and the lamp housing 1 more compact, reducing the space occupied, and making the rotation of the lower light-blocking blade 31 more stable.

[0024] For example, the area of ​​the upper light-blocking leaf 21 and the area of ​​the lower light-blocking leaf 31 are both larger than the area of ​​the light outlet 11, ensuring good light-blocking effect.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
