Urban landscape lighting and night scene lighting projects, which are carried out by garden trees, bridges, commercial buildings, etc., have become the driving force behind the new value of urban aesthetics and urban space.

[0003] Landscape trees, bridges, commercial buildings, generally use LED floodlights to focus the light and illuminate them, making them show optical beauty. However, there are often many places that are not satisfactory and have flaws.

[0004] LED floodlights will produce glare when projecting onto a target object, which will make the viewers or pedestrians feel dazzling, causing the contrast, vision, recognition speed and other functions of the eyes to decline, resulting in eye fatigue and discomfort, and in severe cases, it can make people dizzy. Being in the glare area for a long time will also have a significant impact on people's psychology, such as irritability and slow reaction.

[0005] In the prior art, LED floodlights use circular hole grille plates to suppress glare, but the effect of suppressing glare is relatively general, and there are still problems such as partial glare, light spots and uneven beam distribution. In addition, the circular hole grille plate is assembled into one with the internal optical components of the LED floodlight by bolts, and then the whole is installed in the lamp housing. Due to the lack of a positioning structure, when it is assembled in the lamp housing, it is easy to cause assembly deviation or assembly difficulty, which is not conducive to assembly.

[0043] Embodiment 1

[0044] As Figures 1 to 7 shown, in one of the embodiments of the present application, a vertical-tooth round-hole grating is provided, including a grating plate 1 and a plurality of cylinders 2 connected to the grating plate 1. It is characterized in that: the grating plate 1 and the plurality of cylinders 2 are integrally formed and orthogonally arranged, the grating plate 1 and the plurality of cylinders 2 are provided with an interconnected optical channel 21, along the length direction of the optical channel 21, a plurality of tooth grooves 22 are provided on the inner wall of the optical channel 21, the grating plate 1 is connected with a plurality of hollow studs 11 on one side close to the plurality of cylinders 2, the plurality of hollow studs 11 and the grating plate 1 and the plurality of cylinders 2 are integrally formed, along the circumferential direction of the grating plate 1, a plurality of first convex parts 12 and first concave parts 13 are provided on the outer periphery of the grating plate 1, and the first convex parts 12 and the first concave parts 13 are used to be respectively adapted and limited with the second concave parts and the second convex parts on the inner surface of the external lamp housing (not shown in the figure);

[0045] On the one hand, in this embodiment, a plurality of cylinders are connected to the grating plate. The grating plate and the plurality of cylinders are integrally formed and orthogonally arranged. The grating plate and the plurality of cylinders are provided with an interconnected optical channel, and a plurality of tooth grooves are provided on the inner wall of the optical channel. Through the toothed design on the inner circumferential surface of the optical channel, the light can be better dispersed, the light beam distribution is uniform, the glare phenomenon is reduced, and the spot problem is improved. In the traditional round-hole grating, the inner surface of its optical channel is a smooth structure design with a smoothly connected curved surface, and the light is controlled through the round holes, and the effect is not as good as that of the optical channel with tooth grooves, the light dispersion effect is poor, and the light beam distribution is uneven;

[0046] On the other hand of this embodiment, a number of first convex portions and first concave portions are provided on the outer periphery of the grille plate. The first convex portions and the first concave portions are used to respectively fit and limit with the second concave portions and the second convex portions on the inner surface of the external lamp housing, so as to realize the positioning of the grille plate in the circumferential position within the lamp housing, providing a basis for the positioning structure, facilitating the subsequent overall installation of the internal optical components into the lamp housing, avoiding the problem of assembly deviation, and improving the assembly efficiency.

[0047] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, in the above embodiment, further, a number of the cylinders 2 are integrally formed with each other;

[0048] In this embodiment, a number of cylinders are integrally formed with each other, which can enhance the structural stability of the grille plate.

[0049] As Figure 1 and Figure 2 shown, in the above embodiment, further, at least three first convex portions 12 are provided;

[0050] In this embodiment, through the design of three first convex portions, a triangular stable structure can be formed to ensure that the grille plate is not prone to rotation in the circumferential direction, resulting in problems such as assembly deviation or structural instability with the lamp housing.

[0051] As Figure 1 , Figure 2 and Figure 7 shown, in the above embodiment, further, the cross-section of the optical channel 21 is circular, the cross-section of the tooth groove 22 is V-shaped, the inner diameter D1 of the cross-section of the optical channel 21 ranges from 33.5 to 35 mm, and the wall thickness d1 of the optical channel 21 ranges from 0.7 to 2.2 mm;

[0052] In this embodiment, the tooth grooves on the inner surface of the optical channel are designed in a V-shaped structure, which can disperse and guide the light beam. By changing the propagation path of the light beam through the physical structure of the tooth grooves, a specific lighting effect can be achieved. Specifically: the tooth grooves divide the light beam into multiple small light beams, making the light more evenly distributed in different directions, increasing the uniformity and coverage of the floodlighting, and at the same time, the propagation direction of the light beam can be controlled to ensure that the light propagates along the preset path, avoiding the light directly irradiating the areas that do not need to be illuminated, improving the utilization rate of the light, and reducing the glare phenomenon;

[0053] The inner diameter range of the cross-section of the optical channel depends on the mirror size of the optical lens and the depth of the tooth groove, and the two only need to be the same; if the inner diameter of the cross-section of the optical channel is too large, the beam dispersion effect will be poor, weakening the beam transmission ability. On the contrary, if the inner diameter of the cross-section of the optical channel is too small, problems such as weak beam intensity and small coverage range will occur;

[0054] The wall thickness range of the optical channel depends on the structural support ability of the grille plate and the depth of the tooth groove.

[0055] As Figure 2 shown, in the above embodiment, further, the center distance d2 between the centers of every two adjacent optical channels 21 ranges from 34.2 to 37.2 mm;

[0056] In this embodiment, after determining the inner diameter range of the cross-section of the optical channel and the wall thickness range of the optical channel, the dimension range of the center distance between every two adjacent optical channels is designed, which can ensure a compact structure while maintaining the beam effect.

[0057] As Figure 2 and Figure 4 shown, in the above embodiment, further, every three pairwise adjacent optical channels 21 form a hollow triangular prism 23;

[0058] In this embodiment, every three pairwise adjacent optical channels form a hollow triangular prism, which makes the grille plate and several cylinders form a relatively stable structure relying on the triangular prism, enhancing the anti-deformation ability of the grille plate.

The vertical-tooth round-hole grille is located between the light-transmitting plate and the optical film, and the optical lens is located between the honeycomb grille and the lamp board. The double-grille structure design of the vertical-tooth round-hole grille and the honeycomb grille can control glare to a greater extent, improve lighting comfort. The design of the optical film is used to improve the light distribution and lighting effect, solve the spot problem, widen the irradiation angle, and reduce blue light spillage, thereby improving the beam effect of the floodlight as a whole, and being green and energy-saving.

[0063] As Figures 9 to 11 shown, in the above embodiment, further, at least three support rods 61 are provided on one side of each optical lens 6 close to the lamp board 7, and the lamp board 7 is provided with the same number of limit holes 71 at the corresponding positions of the support rods 61. The support rods 61 are inserted into the limit holes 71 in a matching manner, and each optical lens 6 is opposite to the optical channel 21 on the side far from the lamp board 7;

[0064] In this embodiment, three support rods are designed on the optical lens, and the lamp board is provided with the same number of limit holes at the corresponding positions of the support rods, so that the support rods are inserted into the limit holes in a matching manner, thereby further stabilizing the structural stability of the optical lens on the lamp board. And making each optical lens opposite to the optical channel one by one can ensure the beam dispersion effect, beam transmission ability, beam intensity and beam coverage range.

[0065] As Figure 8 、 Figure 10 and Figure 11 shown, in the above embodiment, further, the optical film 4, the honeycomb grille 5, and the lamp board 7 are provided with screw holes 8 at the corresponding positions of the hollow studs 11.
