[0002] As a facility for lighting roads, street lamps have the following main functions: 1. Provide lighting for pedestrians and vehicles. In the case of night and bad weather, they can illuminate the road, enabling pedestrians and drivers to clearly see the road ahead and obstacles, and reducing the occurrence of traffic accidents. 2. Improve traffic efficiency. The lighting of street lamps can improve the visibility of the road.

[0003] Traditional street lamps mainly consist of components such as light sources, housings, radiators, and lenses. The arrangement of street lamps on the street can be single-sided or double-sided. Among the existing street lamps, although they can meet the basic street lighting requirements, there are many problems. For example, the lamps can only be applied to one type of lane; only one arrangement method can be used for lamp installation. Moreover, the layout of street lamps is often restricted by factors such as road grade, traffic flow, speed, road width, road surface structure, and lamp power, resulting in different layouts. As a result, the products need to be customized according to the specific road conditions, which is not conducive to large-scale production. Summary of the Utility Model

[0036] As Figures 1 to 7 shown, a new type of street lamp applicable to multiple lanes is successively provided with a frame cover 1, a lens layer 2, an aluminum substrate layer 3 and a radiator layer 4;

[0037] The frame cover 1 is provided with a receiving cavity 5;

[0038] The lens layer 2 is placed inside the frame cover 1, and a first arc surface 6 is arranged on the top surface of the lens layer 2, and the first arc surface 6 is exposed outside the receiving cavity 5;

[0039] A second arc surface 7 for cooperating with the first arc surface 6 is arranged on the bottom surface of the lens layer 2;

[0040] The top surface of the aluminum substrate layer 3 abuts against the bottom surface of the lens layer 2, and an LED lamp board 10 is arranged on the aluminum substrate layer 3;

[0041] An adaptation cavity 8 for inserting and embedding the lens layer 2 and the aluminum substrate layer 3 is arranged on the top surface of the radiator layer 4.

[0042] Specifically, as Figure 2 shown, both the first arc surface 6 and the second arc surface 7 are designed as hemispherical surfaces, and the selected material is high-silicon boron glass.

[0043] Furthermore, a plurality of first arc surfaces 6 are arranged and distributed along the top surface of the lens layer 2.

[0044] Furthermore, the number of the second arc surfaces 7 is corresponding to the number of the first arc surfaces 6, and is vertically corresponding to the arrangement position of the first arc surfaces 6.

[0045] Specifically, as Figure 6 shown, multiple LED lamp boards 10 are provided and are correspondingly arranged below the second arc surface 7.

[0046] Through the above design, in a specific application example, high-color-rendering, high-energy-efficiency, and long-life LEDs are selected as the light source of the lamp. The single-module light sources can be evenly arranged in the form of 8 rows and 2 columns below the lens optical surface.

[0047] Specifically, as Figure 3 shown, the frame cover 1 is also provided with a first mounting hole 11 for connecting the radiator layer 4.

[0048] Furthermore, multiple first mounting holes 11 are provided and are spaced apart along the edge of the frame cover 1.

[0049] Specifically, as Figure 7 shown, the radiator layer 4 is provided with second mounting holes 12 that are used in cooperation with the first mounting holes 11.

[0050] Furthermore, multiple second mounting holes 12 are provided and are vertically corresponding to the first mounting holes 11.

[0051] Specifically, as Figure 7 shown, a plurality of heat dissipation fins 9 are evenly distributed on the bottom surface of the radiator layer 4.

[0052] The lens of the present utility model adopts a novel optical overlapping arrangement method. By precisely shooting the lens curvature of its side wall, the light can meet the lighting requirements while minimizing the light hitting the frame, thereby improving the light utilization rate.

[0053] The working principle of this product is that the lens material used is borosilicate glass. Taking an ideal optical system as an example, the light source is a Lambert source. Through the principle of light expansion conservation, most of the light emitted by the lamp beads is refracted into the lens, and then the light is reflected by the arc surfaces with different curvatures inside. To satisfy the law of refraction of light: n1sinθ1 = n2sinθ2, it can be known that θ1 and θ2 are the incident angle and the refraction angle respectively. n1 is the refractive index of air, n2 is the refractive index of borosilicate glass, which is 1.47. According to the Lambert source with an angle of 120°, this product controls the height and curvature of the lens light entrance so that the incident light is evenly irradiated to both sides at an angle: when light enters from an optically thinner medium to an optically denser medium, the incident angle > the refraction angle; when light enters from an optically denser medium to an optically thinner medium, the incident angle < the refraction angle.

[0054] It can be seen that according to the above refraction law formula, when light enters the air from glass, the critical angle is approximately 41.5°. Therefore, when the light exits from the upper spherical surface, the incident angle is greater than the critical angle, and the light will undergo total internal reflection inside the lens and cannot exit. To obtain a large-angle outgoing light of 135°, the incident angle needs to be controlled at about 45°.

[0055] Based on the above, it can be concluded that in actual application examples, when the lens is to achieve an angle of 135°, there will always be light with an angle of 3.5° undergoing total internal reflection inside the lens. Therefore, to improve the light loss caused by total internal reflection, the first arc surface 6 and the second arc surface 7 adopt a novel method of optical surface overlapping arrangement. By restricting the quantization conditions, its edge thickness is 6.5 mm, the distance from the fixed point of the lens curve to the lowest surface of the lens is 11.64 mm, the total length of the lens is 113 mm, and the width is 67 mm. The LED lamp board 10 is attached to the bottom surface of the second arc surface 7. The advantage of this design is that while the light meets the lighting requirements, it does not irradiate the frame as much as possible, improving the utilization rate of light. At the same time, the lens process in this design is unique, which can achieve an ideal polarization effect while ensuring that the light efficiency is not lower than that of common glass lenses on the market. Among them, the schematic diagram of the light path of the lens can be as Figure 9 shown.

[0056] The CJJ45 - 2015 standard involved in this design is shown in the following table:

[0057]

[0058] This utility model is applicable to various arrangement methods of street lamps and is suitable for multi - lane roads. Specifically, all data of the lamp meet the national standards for road and street lighting and are superior to the data of market competitors, achieving an ideal lighting effect. The simulated data table of the lamp is shown in the following table. Among them, the first - row data in each index cell is the data of this scheme, and the second - row data is the data of competitors. The schematic diagram of the lamp effect can be referred to Figure 8 shown.

[0059]

[0060]

[0061] Through the precise design of the lens, this utility model realizes multi - direction light control, makes the light exit towards the road, and achieves the effect of high uniformity. The installation height of this product is suitable for 10 meters and 12 meters. And for sections with less than three lanes, the lamp does not need to be tilted for irradiation. At the same time, the lamp is applicable to various arrangement methods of street lamps and does not need to replace the lamp.

[0062] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
