[0033] A building window light-shielding structure for preventing light pollution, such as Figures 1 - 3As shown in the figure, it includes a window frame 10. On both sides of the window frame 10, an indoor tempered glass 50 and an outdoor tempered glass 60 are respectively arranged. A retractable light-shielding inner curtain 20 is arranged between the indoor tempered glass 50 and the outdoor tempered glass 60. At the top of the window frame 10, a top box 30 for controlling the rolling and unrolling of the light-shielding inner curtain 20 is installed; at the bottom of the light-shielding inner curtain 20, a weighted bottom rod 21 is installed; inside the top box 30, a rolling and unrolling rotating shaft 31 for driving the rolling and unrolling of the light-shielding inner curtain 20 is installed. One end of the rolling and unrolling rotating shaft 31 is installed with a forward and reverse reduction motor 32, and the end of the rolling and unrolling rotating shaft 31 far from the forward and reverse reduction motor 32 is installed with a bearing seat 33; between the indoor tempered glass 50 and the light-shielding inner curtain 20, a number of groups of supplementary light tubes 40 are arranged in a uniform and equidistant manner. Through the double-layer tempered glass design of the set indoor tempered glass 50 and outdoor tempered glass 60, it not only enhances the safety and sound insulation effect of the window, but also can block the direct sunlight from the outside to a certain extent, reducing the direct impact of light pollution on the indoor environment. The flexible rolling and unrolling design of the light-shielding inner curtain 20 enables users to adjust the indoor light intensity according to actual needs. The forward and reverse reduction motor 32 built in the top box 30 drives the rolling and unrolling rotating shaft 31 to realize the automatic rolling and unrolling of the light-shielding inner curtain 20, with convenient operation and precise control, greatly improving the convenience and comfort of use. The weighted bottom rod 21 installed at the bottom of the light-shielding inner curtain 20 effectively increases the draping feeling of the curtain, preventing it from moving due to wind or slight touch in the non-use state, and ensuring the stability and durability of the light-shielding effect. The supplementary light tubes 40 arranged between the indoor tempered glass 50 and the light-shielding inner curtain 20, through the uniform and equidistant arrangement method, can provide soft and uniform light for the indoor when the light-shielding inner curtain 20 is lowered, making up for the insufficient light caused by light shielding, and ensuring the comfort and visual experience of the indoor light.

[0034] Furthermore, on the inner walls of both sides of the window frame 10, lifting chutes 11 with a T-shaped cross-section are opened. The length of the weighted bottom rod 21 is the same as the width of the inner walls of both sides of the window frame 10. At both ends of the weighted bottom rod 21, lifting sliders 22 that are adapted to the size of the lifting chutes 11 and are in sliding fit are installed, making the rolling and unrolling process of the light-shielding inner curtain 20 smoother and reducing the noise and wear generated by friction.

[0035] Among them, the light-shielding inner curtain 20 is made of a dark-colored light-shielding canvas or flocked cloth material, and the thickness is 2-4 mm, so that the light-shielding inner curtain 20 has a good light-shielding effect, can effectively block the outside light and line of sight, and protect the indoor privacy.

[0036] Specifically, at both ends of the supplementary light tubes 40, limit seats 41 installed on the inner wall of the window frame 10 and used for limiting the indoor tempered glass are provided, which not only provide a stable installation position for the supplementary light tubes, but also limit them through the indoor tempered glass, ensuring the stability and safety of the supplementary light tubes during installation and use.

[0037] It should be noted that sealing rings 51 are provided at the edges of the indoor tempered glass 50 and the outdoor tempered glass 60, effectively improving the sealing performance of the window.

[0038] In addition, both the indoor tempered glass 50 and the outdoor tempered glass 60 are in interference fit with both sides of the window frame 10, and limit pins are provided on both sides to prevent the glass from loosening or falling off due to wind pressure or other external forces.

[0039] The working principle of the light pollution prevention building window light-shielding structure: When the indoor light intensity needs to be adjusted, the user can start the forward and reverse reduction motor 32 by controlling a switch (not directly shown in the figure and connected to the forward and reverse reduction motor 32 for control). After the forward and reverse reduction motor 32 is started, it drives the winding and unwinding shaft 31 to start rotating. If it is necessary to lower the light-shielding inner curtain 20 to reduce the light, the motor will rotate in the set direction, causing the winding and unwinding shaft 31 to release the light-shielding inner curtain 20. The light-shielding inner curtain 20 will smoothly fall under its own weight and the action of the weighted bottom rod 21 until it reaches the required position. If it is necessary to increase the light, the forward and reverse reduction motor 32 is operated in the reverse direction, causing the winding and unwinding shaft 31 to rotate in the reverse direction and roll up the light-shielding inner curtain 20 into the top box 30.

[0040] When the light-shielding inner curtain 20 is completely lowered, if the indoor light is insufficient, the user can start the supplementary light tube 40 through the control panel. The supplementary light tube 40 starts to work, emitting soft and uniform light. Through the scattering of the indoor tempered glass 50, it provides a suitable lighting environment for the interior, making up for the problem of insufficient light caused by light shielding.

[0041] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
