Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, specifically to a small-volume linear floodlight with anti-glare function. Background Technology

[0002] Linear floodlights are long, strip-shaped lighting devices designed to provide linear, uniform illumination. They are commonly used in commercial, industrial, and architectural lighting.

[0003] Currently, existing technologies still have the following areas for improvement: In order to achieve better light source utilization and anti-glare effects, and to avoid glare on the sides and length of the lamp, vertically installed linear floodlights on the market often use a tilted lamp body or a special polarizing lens to change the light output direction, and use glass screen printing for asymmetrical light cut-off to control the light output angle. The former solution requires a large assembly space due to the tilted lamp body, which is sometimes difficult to meet on-site conditions. The latter solution has a complex and time-consuming special polarizing lens design, is uneconomical, and cannot be shared with other projects. Asymmetrical light cut-off cuts off the strong light output area within the beam angle, resulting in a darker wall washing effect and reducing the utilization rate of the light source. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a small-volume linear floodlight with anti-glare function, which can achieve high light source utilization, good anti-glare effect, and small overall size, making it suitable for a wide range of applications.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A small-volume linear floodlight with anti-glare function includes a lampshade, a lamp body, and a rotating assembly. The lampshade is fixedly connected to the top of the lamp body, and the rotating assembly is fixedly connected to one side of the lamp body.

[0007] The lamp body is equipped with an anti-glare device, an optical lens, a circuit board, a first slot and a second slot. The anti-glare device is fixedly connected to the second slot, the circuit board is fixedly connected to the first slot, and the optical lens is fixedly connected between the circuit board and the anti-glare device.

[0008] The rotating assembly includes a first bracket, a rotating shaft, a bolt, and a second bracket. The rotating shaft is rotatably connected to the first bracket, and the second bracket is fixedly connected to the lower side of the lamp body by the bolt.

[0009] Preferably, the anti-glare device is provided with anti-glare fins inside, and there are multiple anti-glare fins, which are arranged perpendicular to the bottom of the anti-glare device.

[0010] Preferably, a light source is provided on the circuit board, and the position of the light source corresponds to the position of the optical lens.

[0011] Preferably, the circuit board is arranged at an angle.

[0012] Preferably, the second bracket is a single unit, with the left half of the second bracket being cylindrical and the right half being U-shaped, and the left half of the second bracket being fitted onto the rotating shaft.

[0013] Preferably, the first bracket is L-shaped, and a through hole is provided on the vertical section of the L-shape of the first bracket.

[0014] Preferably, the rotating shaft passes through a through hole in the L-shaped vertical section of the first bracket.

[0015] Preferably, the bottom of the first bracket and the bottom of the lamp body are not on the same horizontal plane, and the horizontal plane of the bottom of the first bracket is lower than the horizontal plane of the bottom of the lamp body.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By setting up the lampshade and lamp body, the technical effect that can be achieved is that the circuit board inside the lamp body is set at an angle. When the lamp is installed on a vertical wall, the optical lens inside the lamp can be tilted at an angle to the illuminated surface, so that the light-emitting area with the highest light intensity of the optical lens is aligned with the geometric center of the illuminated surface. This makes it convenient to perform directional light blocking and anti-glare design only on the stray light area outside the beam angle and the light-emitting area within the edge angle within the beam angle that will cause glare. This prevents the direct emission of light in this area, while ensuring that the light emission of the light-emitting area with higher light intensity is not affected. The anti-glare effect is good and the utilization rate of the light source is high. When the lamp is installed, there is no need to tilt the entire lamp, which reduces the lamp installation space that needs to be reserved, ensures high space utilization, and has a high aesthetic appeal after installation. It has a wide range of application scenarios.

[0018] (2) By setting up the lampshade and lamp body, the technical effect that can also be achieved is that the anti-glare device inside the lamp body has a symmetrical light-cutting and anti-glare design. The anti-glare device fins are symmetrically distributed around the center of the optical lens, ensuring that the light emitted by the optical lens still has a symmetrical beam angle after being filtered by the anti-glare device. The light projected onto the illuminated surface is also more uniform and the transition is more natural. Furthermore, due to the symmetrical distribution, it greatly ensures that the light in the luminous area with a higher luminous intensity located in the center of the optical lens beam angle is emitted normally, thereby improving the utilization rate of the light source.

[0019] (3) By setting up the lampshade and lamp body, the technical effect that can also be achieved is that the anti-glare fins inside the lamp body have a certain height, which can cut off the invalid light projected onto the illuminated surface from the top light-emitting surface of the optical lens, and avoid glare to indoor people in the same horizontal space as the light-emitting surface. When multiple lamps are installed at the same time, the setting of the anti-glare device can ensure that the beam emitted from the light-emitting surface of each lamp at different positions has the same length in the irradiation area of ​​the illuminated surface, and form a beam overlap area with uniform light effect on the illuminated surface, cutting off redundant light emitted along the Z-axis extension direction of the illuminated surface, avoiding direct and indirect glare when indoor and outdoor people observe other things near the illuminated surface or light-emitting surface from the vertical direction, and ensuring the anti-glare effect of the lamp.

[0020] (4) By setting a rotating component, the technical effect that can be achieved is that the bottom of the first bracket and the bottom of the lamp body are not on the same horizontal plane. The horizontal plane of the bottom of the first bracket is lower than the horizontal plane of the bottom of the lamp body, so that the lamp can be finely adjusted in two directions. This helps to overcome the problem that the lamp cannot be installed on the ideal plane due to the complex on-site installation environment, which in turn affects the angle between the lamp's optical lens and the illuminated surface, thus affecting the light output direction.

[0030] Reference Figures 1 to 3 The present invention discloses a small-volume linear floodlight with anti-glare function, including a lampshade 1, a lamp body 2 and a rotating component. The lampshade 1 is fixedly connected to the top of the lamp body 2, and the rotating component is fixedly connected to one side of the lamp body 2.

[0031] The lamp body 2 is equipped with an anti-glare device 3, an optical lens 4, a circuit board 6, a first slot 11 and a second slot 12. The anti-glare device 3 is fixedly connected to the second slot 12, the circuit board 6 is fixedly connected to the first slot 11, and the optical lens 4 is fixedly connected between the circuit board 6 and the anti-glare device 3.

[0032] The rotating assembly includes a first bracket 7, a rotating shaft 8, a bolt 9, and a second bracket 10. The rotating shaft 8 is rotatably connected to the first bracket 7, and the second bracket 10 is fixedly connected to the lower side of the lamp body 2 by the bolt 9. The second bracket 10 is arranged as a single unit on both sides. The left half of the second bracket 10 is cylindrical, and the right half is U-shaped. The left half of the second bracket 10 is sleeved on the rotating shaft 8.

[0033] Reference Figure 1 and Figure 3The anti-glare device 3 contains multiple anti-glare fins 5, which are arranged perpendicularly to the bottom of the device. A light source is mounted on the circuit board 6, with its position corresponding to the optical lens 4. The circuit board 6 is tilted, allowing the optical lens 4 inside the device to be angled relative to the illuminated surface when the light fixture is installed on a vertical wall. This ensures that the area of ​​the optical lens 4 with the highest luminous intensity is aligned with the geometric center of the illuminated surface. This allows for targeted anti-glare design, focusing only on stray light areas outside the beam angle and glare-causing areas within the edge angle of the beam angle. This prevents direct light emission from these areas while ensuring that the light emission from areas with high luminous intensity remains unaffected. The anti-glare effect is excellent, and the light source utilization is high. During installation, there is no need to tilt the entire light fixture, reducing the required installation space and ensuring high space utilization. The finished product is aesthetically pleasing and suitable for a wide range of applications.

[0034] The anti-glare device 3 features a symmetrical light-cutting and anti-glare design. The anti-glare device fins 5 are symmetrically distributed around the center of the optical lens 4, ensuring that the light emitted from the optical lens 4 still has a symmetrical beam angle after being filtered by the anti-glare device 3. The light projected onto the illuminated surface is also more uniform and the transition is more natural. Furthermore, due to the symmetrical distribution, it greatly ensures that the light from the light-emitting area with higher luminous intensity located at the center of the beam angle of the optical lens 4 can be emitted normally, thereby improving the utilization rate of the light source.

[0035] The anti-glare fins 5 inside the anti-glare device 3 have a certain height, which can block the invalid light projected onto the illuminated surface from the top light-emitting surface of the optical lens 4, thus avoiding glare for indoor personnel in the same horizontal space as the light-emitting surface. When multiple lamps are installed at the same time, the anti-glare device 3 can ensure that the beams emitted from the light-emitting surfaces of lamps at different positions have a consistent length in the irradiated area of ​​the illuminated surface, and form a uniform beam overlap area on the illuminated surface. It blocks redundant light emitted along the Z-axis extension direction of the illuminated surface, thus avoiding direct and indirect glare felt by indoor and outdoor personnel when observing other objects near the illuminated surface or light-emitting surface from the vertical direction, ensuring the anti-glare effect of the lamps.

[0036] Reference Figures 1 to 2 The first bracket 7 is L-shaped, and a through hole is provided on the vertical section of the L-shape of the first bracket 7; the rotating shaft 8 passes through the through hole on the vertical section of the L-shape of the first bracket 7; the bottom of the first bracket 7 is not on the same horizontal plane as the bottom of the lamp body 2, and the horizontal plane of the bottom of the first bracket 7 is lower than the horizontal plane of the bottom of the lamp body 2, so that the lamp can be finely adjusted in two directions. This helps to overcome the problem that the lamp cannot be installed on the ideal plane due to the complex on-site installation environment, which in turn affects the angle between the lamp optical lens 4 and the illuminated surface, thus affecting the light output direction.

[0037] The working principle and usage process of this utility model are as follows: The lamp is installed on the wall through the first bracket 7, and the lamp is adjusted to a suitable angle through the second bracket 10 and the rotating shaft 8.

[0038] When the power is turned on, the light beam emitted by the light source on the circuit board 6 is emitted through the optical lens 4, passes through the anti-glare device 3 to prevent people from feeling glare when observing, and is projected onto the illuminated surface through the lampshade 1.
