[0030] The following is a further detailed description of this application with reference to the accompanying drawings and specific implementations:

[0031] like Figure 3-Figure 5 The illustrated combined anti-glare lampshade comprises a grille cover 1, a lamp holder 2, a U-shaped bracket 3, a side light shield 4 and a front light shield 5. The grille cover 1 is provided with a plurality of grille covers that are evenly arranged up and down to form a lampshade body. One side of the lampshade body is fixed to the lamp holder 2 by a fastener. The two ends of the U-shaped bracket 3 are rotatably arranged in the middle of the lamp holder 2 and located on the back of the grille cover 1. The end faces of the side light shield 4 are U-shaped and the two sides of the end are fixedly engaged with the upper two sides of the lampshade body. The front light shield 5 is located on the front of the grille cover 1 and is rotatably arranged on the upper outer end side of the side light shield 4. An adjustment knob 6 is provided at the connection between the U-shaped bracket 3 and the lamp holder 2. Tightening the adjustment knob 6 limits the rotation of the U-shaped bracket 3 and the lamp holder 2. Loosening the adjustment knob 6 allows the U-shaped bracket 3 and the lamp holder 2 to rotate relative to each other to adjust the relative angle. The adjustment knob 6 can be an adjustment bolt.

When the fastening screw 8 is loosened, the front light shield 5 can move within the arcuate slot 7. Accordingly, the front light shield 5 can rotate relative to the side light shield 4 to adjust the relative angle between the two. A scale groove is provided on one side of the adjustment slot to indicate the rotation angle of the front light shield 5. When the fastening screw 8 is tightened, the front light shield 5 is fixed to the side light shield 4.

[0033] like Figure 4 and Figure 5As shown, the grille cover 1 includes a cover body 11 , the interior of the cover body 11 is evenly and fixedly provided with heat sinks 12 , and a well-shaped fixing plate 13 is fixedly provided on one side of the front of the grille cover 1 .

[0034] The U-shaped bracket 3 of the utility model is fixed to the lamp holder 2 together with the grille cover 1. The U-shaped bracket 3 and the lamp holder 2 can rotate relative to each other to further control the side scattered light. The front light shield 5 is designed in the shape of a hat brim and is arranged on the side light shield 4. It can be adjusted to control the upward and downward scattered light. It reduces the scattered light pollution caused by high-power floodlights, improves lighting efficiency, and reduces the impact on the surrounding environment and personnel. The utility model can fully control the upward, downward and side scattered light, is highly practical, and has a good anti-glare effect. The combination of the grille cover 1, the side light shield 4 and the front light shield 5 provides all-round scattered light control. The front light shield 5 is adjustable, which is convenient for adjusting the shading effect according to actual needs. It is convenient and quick to operate and easy to install and maintain.
