Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, unless otherwise specifically defined.
[0029] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] An LED lamp used in parking lots, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it includes a lamp holder 1, a light-transmitting cover 2, a light bar 3 and a lamp cap 4. The lamp holder 1 is used for mounting the base, the light-transmitting cover 2 is covered on the lamp holder 1, the light bar 3 is mounted on the lamp holder 1, and the lamp cap 4 is mounted on the end of the lamp holder 1 and electrically connected to the light bar 3.
[0032] The light-transmitting cover 2 is provided with a convex lens-like refractive structure 5 and a sawtooth-like focusing refractive structure 6 .
[0033] In actual applications, the lamp holder 1 is installed on an installation surface such as a parking lot where a small range of light is required to support the lamp tube and ensure the stability and safety of the lamp tube; the light cover 2 covers the lamp holder 1 to protect the light strip 3 and electronic components inside the LED lamp tube and control the light transmission angle. The light cover 2 can be made of high-transmittance materials such as polycarbonate or polymethyl methacrylate.
[0034] It needs to be further explained that, Figure 1 and Figure 3 As shown, a convex lens-like refractive structure 5 is provided on the light-transmitting cover 2; this structure imitates the shape of a convex lens, can concentrate and refract light, achieve small-angle light emission and reduce glare, thereby improving the lighting effect; at the same time, a sawtooth-like focusing refractive structure 6 is also provided on the light-transmitting cover 2, the shape of which is similar to multiple sawtooth-shaped protrusions; this structure can further control the propagation path of light, ensure that the light is mainly irradiated on the target area, achieve small-angle light emission and light path control, and further improve the lighting effect.
[0035] In practical applications, such as Figure 1 、 Figure 3 and Figure 4 As shown, the convex lens-like refractive structure 5 is arranged opposite to the light bar 3; the sawtooth-like focusing refractive structure 6 is arranged on both sides of the convex lens-like refractive structure 5, and abuts against the outer edge of the lamp holder 1. The convex lens-like refractive structure 5 and the sawtooth-like focusing refractive structure 6 on the light-transmitting cover 2 work together to accurately control the propagation path and distribution range of the light. The convex lens-like refractive structure 5 on the light-transmitting cover 2 faces the light bar 3, ensuring that the light emitted from the lamp beads 302 can be effectively collected and guided, thereby improving the directionality and efficiency of the lighting. The sawtooth-like focusing refractive structure 6 is arranged on both sides of the convex lens-like refractive structure 5, and tightly abuts against the outer edge of the lamp holder 1, forming a stable support. The convex lens-like refractive structure 5 can refract light, thereby ensuring that the light is more directly and concentratedly irradiated to the target area.
[0036] In practical applications, the surface of the sawtooth-like light-concentrating refractive structure 6 may be coated with a metal, anti-reflection or nano-composite coating to improve the reflectivity and refractive index.
[0037] In practical applications, such as Figure 3As shown, the convex lens-like refractive structure 5 is arranged along the length direction of the light-transmitting cover 2, which can ensure that the light is evenly distributed in the entire lighting area, avoid uneven brightness or shadow areas, and improve the comfort and safety of parking lot users.
[0038] In practical applications, such as Figure 1 and Figure 4 As shown, the sawtooth-like concentrating refractive structure 6 includes multiple sawtooth-shaped protrusions 7 arranged in a wing-shaped pattern. The sawtooth-shaped protrusions 7 increase their contact area with light, allowing each light beam to be precisely guided. The sawtooth-shaped protrusions 7 are arranged at specific intervals and angles. This layout ensures that light is refracted in the desired direction as it passes through each protrusion, effectively controlling the direction of light propagation.
[0039] In practical applications, such as Figure 1 、 Figure 4 As shown, the lamp holder 1 is provided with two slots 8, which are arranged opposite each other and engage with the light bar 3. The slots 8 provide a stable support platform for securing and positioning the light bar 3, ensuring a stable installation within the lamp holder 1 and minimizing displacement caused by vibration or external forces. The design of the slots 8 allows the light bar 3 to maintain an appropriate distance from the power connector and other electronic components, thereby optimizing heat dissipation and protecting circuit safety.
[0040] In practical applications, such as Figure 5 As shown, the light bar 3 includes a lamp board 301 and a plurality of lamp beads 302, and the plurality of lamp beads 302 are arranged at intervals on the lamp board 301, and the lamp board 301 is clamped between two slot frames 8. The lamp beads 302 are evenly spaced on the lamp board 301, and such a layout ensures uniform distribution of light and efficient luminescence. The material of the lamp board 301 can be aluminum or ceramic, etc., as long as it has good thermal conductivity and electrical insulation properties. The size and shape of the lamp board 301 are adapted to the slot frame 8 in the lamp holder 1, and are connected by means of slot clamping, wedge clamping, or magnetic fixing, etc., to ensure that the lamp board 301 will not loosen or shift after installation and to improve maintenance efficiency. When the lamp beads 302 need to be replaced or repaired, the lamp board 301 can be quickly disassembled without the need to maintain the entire lamp holder 1.
[0041] In practical applications, such as Figure 2 、 Figure 4 As shown, the lamp holder 1 is provided with positioning holes 9 on both sides, and the lamp head 4 is provided with a snap-fit connector 10 corresponding to the positioning holes 9. The snap-fit connector 10 engages with the positioning holes 9. The positioning holes 9 are typically designed as circular or square through-holes, while the snap-fit connector 10 is designed as an insert such as a cylindrical, square, or other shaped snap-fit pin or wedge that matches the positioning holes 9. Only when the positioning holes 9 and the snap-fit connector 10 are properly aligned can they be inserted and locked, ensuring a secure connection between the lamp head 4 and the lamp holder 1.
[0042] In practical applications, such as Figure 1 and Figure 3 As shown, the light-transmitting cover 2, the convex lens-like refractive structure 5 and the sawtooth-like focusing refractive structure 6 are an integrally formed design, which can effectively reduce the connection gaps that may appear in the traditional assembly method, enhance the overall mechanical strength of the light-transmitting cover 2, and at the same time ensure that the light can be effectively refracted and focused along a predetermined path when passing through the light-transmitting cover 2, thereby improving the uniformity and directionality of the lighting.
[0043] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
