DETAILED DESCRIPTION

[0020] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figures 1 to 4 As shown, a preferred embodiment of the present invention is a sunlight protection mechanism for a lamp, the sunlight protection mechanism is arranged on a support frame 7 in the lamp, the sunlight protection mechanism includes a sunshade curtain 1, a motor 2, and a connecting seat 3, the motor 2 is provided with a motor fixing plate 21, the sunshade curtain 1 is located below the lens 8, the motor fixing plate 21 is connected to the support frame 7, the motor fixing plate 21 has a positioning member 4, the connecting seat 3 is connected to the output shaft of the motor 2, one end of the sunshade curtain 1 is provided with a curtain fixing plate 11, the other end of the sunshade curtain 1 is provided with a curtain rotating plate 12, the curtain fixing plate 11 is fixed to the support frame 7, and the curtain rotating plate 12 is provided with a connecting plate 13 connected to the connecting seat 3; when the sunshade curtain 1 is unfolded, the connecting plate 13 is abutted against the positioning member 4, and the sunshade curtain 1 blocks the light output of the lens 8 of the lamp; when the sunshade curtain 1 is retracted, the sunshade curtain 1 does not block the light output of the lens 8 of the lamp, and the lens 8 is located at the lens 91 of the housing 9.

[0023] The utility model rotates the fixing plate 11 of the blackout curtain 1 through the motor 2, so that the blackout curtain 1 is in an expanded or retracted state. When the blackout curtain 1 is expanded, the range of the light output diameter of the lens 8 is completely blocked, thereby achieving a shading effect, preventing the outside sunlight from irradiating the interior of the lamp, avoiding the problem of component damage caused by the focused sunlight, and ensuring the service life of the lamp. When the blackout curtain 1 is retracted, it will not block the light refracted by the lens 8, and will not affect the normal use of the lamp.

[0024] Exemplarily, a Hall element 5 is provided on the motor fixing plate 21, a magnetic steel cooperating with the Hall element 5 is provided on the connecting seat 3, a reset member 6 is connected to the connecting seat 3, one end of the reset member 6 is connected to the connecting seat 3, and the other end of the reset member 6 is connected to the positioning member 4, the Hall element 5 and the motor 2 are electrically connected to the controller of the lamp, when the lamp is powered on, the motor 2 is started synchronously, and the output shaft of the motor 2 drives the curtain rotating plate 12 to rotate through the connecting seat 3 so that the blackout curtain 1 begins to retract, when the magnetic steel is facing the Hall element 5, that is, the magnetic steel on the connecting seat 3 is detected by the Hall element 5, the Hall element 5 feeds back a signal to the controller of the lamp, and the controller of the lamp pauses the motor 2, and the motor 2 stops rotating, so that the blackout curtain 1 is retracted, and at this time the reset member 6 is deformed, so that when the lamp is in use, the sunlight protection mechanism will not block the light refracted by the lens 8, thereby not affecting the normal use of the lamp;

[0025] When the power to the lamp is cut off, the motor 2 loses power synchronously, so that the motor 2 loses its locking torque. Under the reset force of the reset member 6, the curtain rotating plate 12 rotates in the opposite direction and makes the connecting plate 13 rest against the positioning member 4, so that the blackout curtain 1 is unfolded and the range of the light output diameter of the lens 8 is completely blocked, thereby achieving a shading effect, so that the outside sunlight cannot shine into the interior of the lamp.

[0026] Furthermore, the reset member 6 is a torsion spring; the connecting seat 3 is fixedly connected to the top of the output shaft of the motor 2, and the reset member 6 is sleeved on the output shaft of the motor 2 to improve the compactness and stability of the overall structure.

[0027] Specifically, when the blackout curtain 1 is unfolded, the blackout curtain 1 is fan-shaped, effectively blocking sunlight.

[0028] Exemplarily, the positioning member 4 is a positioning pin, and the connecting plate 13 is provided with a groove 131 that cooperates with the positioning pin, so that when the curtain rotating plate 12 is reset, the connecting plate 13 is effectively positioned at the positioning pin, ensuring good stability of the blackout curtain 1 when it is unfolded.

[0029] Specifically, the blackout curtain 1 is a folding curtain, which reduces the space occupied by the blackout curtain 1 after it is folded.

[0030] The present invention also provides a lamp including the aforementioned sun protection mechanism, which is disposed in the housing 9. Since the lamp is provided with the sun protection mechanism, it has all the beneficial effects of the aforementioned sun protection mechanism, which will not be described one by one here.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
