This utility model discloses a safety helmet for underground mining operations. The helmet includes a helmet body, an inner liner fixedly attached to the lower side of the helmet body, a cushioning sponge installed inside the helmet body, a fixed shell fixedly attached to the helmet body, a lighting lamp fixedly attached to the front side of the fixed shell, and a lampshade installed on the front side of the fixed shell. The lighting lamp is located inside the lampshade. A curved cavity is provided inside the fixed shell, and a transparent strip is provided within the curved cavity. The transparent strip is slidably connected to the outside of the lampshade. This utility model uses the output shaft of a motor to drive a rotating roller on the left side to rotate. The two rotating rollers are connected by gear transmission, and the two rotating rollers rotate in different directions. The transparent strip rotates counterclockwise, causing the transparent strip, free of dust inside the fixed shell, to move to the outside of the lampshade. By changing the position of the transparent strip, the light emitted by the lighting lamp is prevented from being obstructed, ensuring the brightness of the lighting.

The utility model relates to a kind of automobile front windshield.It involves new energy automobile technical field.The application specifically includes the outer glass plate and inner glass plate of parallel interval arrangement, and the interlayer cavity formed between outer glass plate and inner glass plate;It also includes light-absorbing structure arranged in interlayer cavity, and photosensitive structure arranged in interlayer cavity, and light-absorbing structure is used to adhere outer glass plate with the inner glass plate, and the strong light of outside shooting is absorbed, and photosensitive structure is used to detect the light intensity of outside shooting.The interlayer cavity formed between outer glass plate and inner glass plate of the utility model is equipped with light-absorbing structure and photosensitive structure, the strong light of outside shooting is absorbed by light-absorbing structure, and the light intensity of outside shooting is detected by photosensitive structure, the blocking effect of the automobile front windshield to strong light is improved, the interference of strong light to driver is reduced, and the law enforcement of road safety supervision department is assisted, so as to ensure driving safety.

The invention discloses an optical module and a vehicle. The optical module comprises a first light guide component and a second light guide component. The first light guide component comprises a light condensing part and a main body part; the main body part is provided with a first light emitting surface; the first light-emitting surface is provided with a first refracting surface, and the first refracting surface is configured to receive light emitted by the first light-emitting surface; the second light guide component is provided with a second incident surface and a second emergent surface; the second light incident surface is provided with a second refracting surface, and the second refracting surface is configured to receive the light refracted by the first refracting surface. Through dimming cooperation at the corners, part of light collimated by the condensation part is gradually emitted to the dark area of the second light-emitting surface, the lighting brightness of the dark area of the second light-emitting surface can be ensured, the dark area is prevented from being formed on the second light-emitting surface, and the lighting uniformity is effectively improved; the designed adjusting path can adjust the light more accurately, and the light can be effectively and accurately refracted to a dark area.
