Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lighting devices, and in particular to a strip floodlight with a built-in anti-glare device. Background Technology
[0002] Glare is a common problem in modern lighting design. Current anti-glare technology for luminaires uses vertical grilles, which can only prevent glare at certain angles of view. For example, when a luminaire shines vertically onto a wall, the viewer is looking at it at an angle, and the vertical grille can suppress glare. However, when the viewer looks directly at the LED at a vertical angle, the grille becomes ineffective, directly entering the viewer's line of sight and producing significant glare that cannot be suppressed.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] The following will combine Figure 1 and Figure 2A detailed description is provided of a strip floodlight with a built-in anti-glare device according to an embodiment of the present invention.
[0017] refer to Figure 1 As shown, the strip floodlight with built-in anti-glare device provided in this embodiment of the utility model includes a support 10, a housing 11 fixed on the support 10, a light source 9 installed inside the housing 11 and a built-in anti-glare device, and a lens 8 fixed on the surface of the housing 11. The built-in anti-glare device is located between the light source 9 and the lens 8. The built-in anti-glare device includes a base 7 and a first anti-glare grille 1, a second anti-glare grille 2, a third anti-glare grille 3, a fourth anti-glare grille 4, a fifth anti-glare grille 5 and a sixth anti-glare grille 6 arranged sequentially from right to left on the base 7. The first anti-glare grille 1 has the largest deflection angle and the sixth anti-glare grille 6 has the smallest deflection angle. The first anti-glare grille 1 has a deflection angle of 25°, the second anti-glare grille 2 has a deflection angle of 20°, the third anti-glare grille 3 has a deflection angle of 15°, the fourth anti-glare grille 4 has a deflection angle of 10°, the fifth anti-glare grille 5 has a deflection angle of 10°, and the sixth anti-glare grille 6 has a deflection angle of 10°.
[0018] refer to Figure 2 As shown, the first anti-glare grille 1, the second anti-glare grille 2, the third anti-glare grille 3, the fourth anti-glare grille 4, the fifth anti-glare grille 5, the sixth anti-glare grille 6, and the base 7 are die-cast integral structures. A snap-fit position is pre-reserved inside the housing 11; the built-in anti-glare device is inserted into the slot and pushed in to secure it inside the housing 11. The built-in anti-glare device is located below the lens 8 and above the light source 9. The built-in anti-glare device contains six anti-glare grilles with different deflection angles. Considering the relationship between illumination distance and deflection angle, when projecting light from the side of the lamp body, the closer the right side is to the wall, the larger the deflection angle of the built-in anti-glare grille, with the first anti-glare grille 1 having a deflection angle of 25°. Similarly, the anti-glare grilles further away from the wall have built-in deflection angles of 20° for the second anti-glare grille 2, 15° for the third anti-glare grille 3, 10° for the fourth anti-glare grille 4, 10° for the fifth anti-glare grille 5, and 10° for the sixth anti-glare grille 6. By sequentially setting anti-glare grilles with different deflection angles, the deflection angle near the wall gradually increases, significantly reducing glare from any viewing angle while ensuring proper lighting of the wall.
[0019] refer to Figure 1As shown in the figure, this utility model provides a strip floodlight with a built-in anti-glare device. The housing 11 is snapped and fixed on the support 10, and the lens 8 is snapped and fixed on the housing 11. When an observer looks vertically from a direct viewing angle, the light projection angle is effectively controlled by setting different deflection angles of the anti-glare grid plates, ensuring that glare is minimized. It can control 60% of the glare to be directed towards the wall, and 40% of the light to be softly spilled out without causing glare to the eyes, thus solving the problem of strong glare caused by looking directly at the light source when side lighting. This utility model provides a strip floodlight with a built-in anti-glare device that combines practicality and concealment. It has a simple structure and provides a visually comfortable lighting environment. Horizontal projection is achieved by using anti-glare grid plates with different deflection angles through the built-in anti-glare device, ensuring uniform and comfortable light.
[0020] This utility model embodiment provides a strip floodlight with a built-in anti-glare device, including a support, a housing fixed on the support, a light source and a built-in anti-glare device installed inside the housing, and a lens fixed on the surface of the housing. The built-in anti-glare device is located between the light source and the lens. The built-in anti-glare device includes a base and a first, second, third, fourth, fifth, and sixth anti-glare grille piece arranged sequentially from right to left on the base. The first anti-glare grille piece has the largest deflection angle, and the sixth anti-glare grille piece has the smallest deflection angle. The built-in anti-glare device has anti-glare grille pieces with different deflection angles. When projecting light from the side, the closer the right side is to the wall, the larger the deflection angle of the built-in anti-glare grille, significantly reducing glare from any viewing angle while ensuring proper illumination of the wall, providing a visually comfortable lighting environment for the viewer.
