Description

Technical Field

[0001] This utility model relates to the field of low light pollution lighting technology, and in particular to a low light pollution lighting fixture. Background Technology

[0002] Low light pollution lighting fixtures are lighting devices designed to reduce light scattering and glare, avoiding unnecessary disturbance to the surrounding environment and living organisms. They typically employ intelligent adjustment systems, low glare designs, and directional lighting technology, effectively reducing light pollution while ensuring lighting needs are met. They are an important means of achieving green lighting and sustainable development.

[0003] A search revealed that existing lighting fixtures often have a fixed illumination direction or use screws or other structures to clamp the support arm for adjustment. Over time, these fixtures are prone to wear and tear, leading to instability and insufficient stability in the adjusted position. This can result in accidental rotation and affect the lighting effect. Therefore, a low-light-pollution lighting fixture is provided to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-light-pollution lamp, comprising: a lamp base, a rotating support arm fixedly connected above the lamp base, a lower light-blocking housing rotatably connected to the inner side of the rotating support arm, multiple sets of locking holes on the side of the lower light-blocking housing, a long threaded rod rotatably connected to the inner side of the side of the lower light-blocking housing with the locking holes, side sliding grooves symmetrically opened on both sides of the lower light-blocking housing, an upper light-blocking housing provided above the lower light-blocking housing, side sliding strips symmetrically fixedly connected to both sides of the upper light-blocking housing, an upper focusing housing fixedly connected above the lower light-blocking housing, a soft light lamp provided inside the lower light-blocking housing, a side fixing block fixedly connected to the side of the rotating support arm, a spring groove opened on the side of the side fixing block near the lower light-blocking housing, a support spring fixedly connected to the inner side of the spring groove, a round-headed top post fixedly connected to the other end of the support spring, and a screw hole block fixedly connected to the inner side of the upper light-blocking housing.

[0006] As a further improvement of this utility model, the long threaded rod extends through the inner side of the lower light-blocking housing.

[0007] As a further embodiment of this utility model: the sliding strip is adapted to the sliding groove, the length of the sliding strip is slightly smaller than the length of the sliding groove, and the sliding strip and the sliding groove are slidably connected.

[0008] As a further improvement of this utility model, multiple sets of light-transmitting holes are evenly opened on the inner sides of both the lower and upper light-blocking housings.

[0009] As a further improvement of this utility model: in normal use, the light-transmitting holes of the lower light-blocking shell and the upper light-blocking shell overlap.

[0010] As a further improvement of this utility model, the inner side of the upper focusing shell near the soft light is designed to be reflective.

[0011] As a further improvement of this utility model: the round-headed top post is adapted to the locking hole, and when the support spring is not subjected to external force and naturally extends, only the round-headed part of the round-headed top post is exposed outside the spring groove and locked into the locking hole.

[0012] As a further improvement of this utility model, a screw hole is provided on the inner side of the screw hole block to match the long threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 4In this embodiment of the utility model, a low light pollution lamp includes: a lamp base 1, a rotating support arm 2 fixedly connected above the lamp base 1, a lower light-blocking housing 3 rotatably connected to the inner side of the rotating support arm 2, a plurality of sets of locking holes 4 opened on the side of the lower light-blocking housing 3, a long threaded rod 5 rotatably connected to the inner side of the side of the lower light-blocking housing 3 with the locking holes 4, side sliding grooves 6 symmetrically opened on both sides of the lower light-blocking housing 3, an upper light-blocking housing 7 provided above the lower light-blocking housing 3, side sliding strips 8 symmetrically fixedly connected to both sides of the upper light-blocking housing 7, an upper focusing housing 10 fixedly connected above the lower light-blocking housing 3, a soft light lamp 11 provided inside the lower light-blocking housing 3, a side fixing block 12 fixedly connected to the side of the rotating support arm 2, a spring groove 13 opened on the side of the side fixing block 12 near the lower light-blocking housing 3, a support spring 14 fixedly connected to the inner side of the spring groove 13, a round-headed top post 15 fixedly connected to the other end of the support spring 14, and a screw hole block 16 fixedly connected to the inner side of the upper light-blocking housing 7.

[0025] The long threaded rod 5 extends into the inner side of the lower light-blocking housing 3. The long threaded rod 5 extends into the lower light-blocking housing 3, ensuring that it can be stably connected to the upper screw hole block 16, and the distance between the lower light-blocking housing 3 and the upper light-blocking housing 7 can be adjusted by rotation.

[0026] The sliding strip 8 is adapted to the sliding groove 6. The length of the sliding strip 8 is slightly less than the length of the sliding groove 6. The sliding strip 8 and the sliding groove 6 are slidably connected. The sliding strip 8 slides in the sliding groove 6, which ensures that the upper light-blocking housing 7 can move smoothly on the lower light-blocking housing 3 without falling off, while restricting the direction of movement.

[0027] Multiple sets of light-transmitting holes are evenly opened on the inner sides of both the lower light-blocking housing 3 and the upper light-blocking housing 7. By evenly opening light-transmitting holes on the lower light-blocking housing 3 and the upper light-blocking housing 7, light can pass through these holes. At the same time, the diffusion range and intensity of the light can be controlled by adjusting the degree of overlap between the two. In normal use, the light-transmitting holes opened on the lower light-blocking housing 3 and the upper light-blocking housing 7 overlap. When the light-transmitting holes overlap, light can be emitted through the overlapping area to form a concentrated beam. The inner side of the upper light-concentrating housing 10 near the soft light 11 is designed to reflect light and focus the light emitted by the soft light 11, thereby improving light utilization and reducing light waste and scattering.

[0028] The round-headed top post 15 is adapted to the locking hole 4. When the support spring 14 is not subjected to external force and naturally extends, only the round head part of the round headed top post 15 is exposed outside the spring groove 13 and locked into the locking hole 4. When the support spring 14 naturally extends, the round head part of the round headed top post 15 is locked into the locking hole 4, thus fixing the lower light-blocking housing 3 after rotation. When it is necessary to adjust the angle, it is only necessary to forcefully pry the lower light-blocking housing 3 to press the round headed top post 15 back into the spring groove 13, and then continue to rotate to the appropriate angle to lock the round headed top post 15 into the appropriate locking hole 4.

[0029] The screw hole block 16 has a screw hole on its inner side that matches the long threaded rod 5. By rotating the long threaded rod 5, the position of the upper light-blocking housing 7 relative to the lower light-blocking housing 3 can be precisely adjusted, thereby changing the overlapping area of ​​the light-transmitting hole and achieving the purpose of adjusting the brightness and reducing light pollution.

[0030] The working principle of this utility model is as follows: the lamp base 1 serves as the foundation of the entire lamp and is placed stably in the required position. The rotating support arm 2 is fixedly connected to the lamp base 1, providing a platform for the lower light-blocking housing 3 to rotate. The lower light-blocking housing 3 is rotatably connected to the inner side of the rotating support arm 2. Initially, the support spring 14 naturally extends, and the round head of the round top post 15 is inserted into an initial locking hole 4, ensuring that the lower light-blocking housing 3 will not rotate arbitrarily when not being operated.

[0031] When the illumination direction of the lamp needs to be adjusted, the user forcefully pries the lower light-blocking housing 3. This action compresses the support spring 14, causing the round-headed top post 15 to disengage from the current locking hole 4. The lower light-blocking housing 3 can then freely rotate to the required angle within a certain range of the rotating support arm 2. After releasing the lower light-blocking housing 3, the support spring 14 returns to its original state, and the round-headed top post 15 is inserted into the new locking hole 4, thus fixing the lower light-blocking housing 3 and completing the adjustment of the illumination direction of the lamp.

[0032] The upper light-blocking housing 7 is slidably connected to the lower light-blocking housing 3 via the side sliding strip 8, ensuring that the upper light-blocking housing 7 can move smoothly on the lower light-blocking housing 3. The user can rotate the long threaded rod 5. Since the long threaded rod 5 passes through the lower light-blocking housing 3 and is adapted to the threaded hole in the threaded hole block 16 of the upper light-blocking housing 7, rotating the long threaded rod 5 will change the relative distance between the upper light-blocking housing 7 and the lower light-blocking housing 3. As the upper light-blocking housing 7 moves, the overlapping area of ​​the light-transmitting holes on the inner side of the lower light-blocking housing 3 and the upper light-blocking housing 7 will change. The larger the overlapping area, the wider the range of light transmission and the higher the brightness. The smaller the overlapping area, the narrower the range of light transmission and the lower the brightness. At the same time, it reduces light scattering and reduces light pollution.

[0033] The light emitted by the soft light 11 is emitted after passing through the light-transmitting holes of the lower light-blocking housing 3 and the upper light-blocking housing 7. The inner side of the upper light-concentrating housing 10 near the soft light 11 is designed to reflect light, which can reflect and focus part of the light emitted by the soft light 11, improve light utilization, and reduce light waste and scattering.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
