Description

Technical Field

[0001] This utility model relates to the field of warning lights, and in particular to a warning light with concentrated light output. Background Technology

[0002] Warning lights play a crucial role in many scenarios where they serve a warning function, such as road construction areas, hazardous work sites, and traffic control points. Their clear and focused light output can effectively attract people's attention, ensuring the safety of personnel and the normal conduct of activities.

[0003] However, many existing warning lights suffer from poorly focused light emission. Due to optical design flaws, the light emitted by some warning lights diverges rapidly during propagation, resulting in a significant decrease in light intensity at greater distances or specific angles, making it difficult to clearly convey warning information. This makes it difficult for warning lights to effectively attract attention over a wide area in some practical applications.

[0004] Furthermore, the lack of focused light emission also leads to poor warning effectiveness. The dispersed light reduces the visual visibility of the warning light. Whether day or night, especially in bright light environments or in adverse weather conditions (such as heavy rain or sandstorms), the light emitted by the warning light is easily obscured by ambient light, making it difficult to highlight the warning sign. This reduces the intended warning effect and fails to provide timely and clear warning signals to potentially endangered personnel, posing a potential risk to production safety and public safety. Therefore, developing a warning light that can achieve focused light emission and improve warning effectiveness is of significant practical importance. Utility Model Content

[0018] (III) Beneficial Effects

[0019] The warning light with concentrated light output provided by this utility model has the following advantages compared with the prior art:

[0020] 1) Concentrated light output significantly improves warning effect; by designing the reflector wall in a trumpet shape and precisely limiting the light output angle range to A~B (A is -10°~-8°, B is 8°~10°), the light emitted by the warning light can be concentrated within a narrow angle range, effectively solving the problem of the non-concentrated light output of existing warning lights; at long distances or specific angles, the light intensity will not be significantly weakened, and the warning information can be clearly transmitted, greatly enhancing the ability of the warning light to attract people's attention over a large area. Whether it is day or night, especially in strong light environments or in severe weather conditions (such as rainstorms, sandstorms, etc.), the warning signs can be highlighted, providing clear and accurate warning signals to people who may be in danger in a timely manner, significantly improving the warning effect and reducing potential risks to production safety and public safety;

[0021] 2) Optimized reflector structure for stable light reflection: The reflector consists of an upper connecting ring, a conical part, and a lower connecting ring, with the reflector wall located on the outer wall of the upper connecting ring and the conical part. This structural design facilitates efficient and stable reflection of the light emitted by the LED beads, ensuring concentrated light emission. The upper connecting ring is located inside multiple LED beads and is fixedly connected to the light panel. The outer diameter of the lower connecting ring is larger than that of the upper connecting ring and is connected to the base, making the connection between the reflector and the light panel and base stable, ensuring the overall stability of the warning light structure, and further optimizing the light reflection effect.

[0038] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0039] See Figures 1 to 9 This utility model provides a warning light with concentrated light output, including a base 1, a reflector 2 mounted on the upper end of the base 1, a lamp plate 3 fixed to the top of the reflector 2, and a lamp cover 4 covering the outside of the reflector 2 and the lamp plate 3. The lamp plate 3 is circular and its shape matches that of the lamp cover 4.

[0040] See Figure 3 and Figure 4 Multiple LED beads 5 are arranged in a ring at intervals on one end (lower end) of the lamp panel 3 facing the reflector 2. A reflective wall 201 corresponding to each LED bead 5 is provided on the reflector 2. The reflective wall 201 is used to reflect the light emitted by the LED beads 5. The reflective wall 201 is trumpet-shaped with a smaller outer diameter at the upper end and a larger outer diameter at the lower end. The reflective wall 201 is configured such that the light emitted by the LED beads 5, after being reflected by the reflective wall 201, forms an output light angle range of A to B, where A is -10° to -8° and B is 8° to 10°. Based on the relationship between the incident angle and the refraction angle, the tilt angle of each segment of the reflective wall 201 can be calculated and designed according to the actual situation, thereby making the light angle range A to B, where A is -10° to -8° and B is 8° to 10°. The above calculation and design process is existing technology and will not be described in detail in this embodiment.

[0041] This structure, by designing the reflector wall in a trumpet shape with a smaller outer diameter at the top and a larger outer diameter at the bottom, and precisely limiting the light emission angle range (A to B, where A is -10° to -8° and B is 8° to 10°) after reflection by the reflector wall, allows the warning light to be concentrated within a narrow angle range, effectively solving the problem of unfocused light emission in existing warning lights. At long distances or specific angles, the light intensity does not significantly decrease, clearly conveying warning information and greatly enhancing the warning light's ability to attract attention over a wider area. Whether day or night, especially in strong light environments or severe weather conditions such as heavy rain or sandstorms, it effectively highlights warning signs, providing timely and accurate warning signals to those potentially facing danger, significantly improving the warning effect and reducing potential risks to production safety and public safety.

[0042] In some embodiments, such as Figures 3 to 8 As shown, the reflector 2 has a hollow structure and includes an upper connecting ring 202 at the top and a tapered portion 203 that smoothly transitions to the upper connecting ring 202. A reflective wall 201 is located on the outer walls of the upper connecting ring 202 and the tapered portion 203. The upper connecting ring 202 is located inside the plurality of LED beads 5 and is fixedly connected to the lamp panel 3. The reflector 2 also includes a lower connecting ring 204 connected to the lower side of the tapered portion 203. The outer diameter of the lower connecting ring 204 is larger than the outer diameter of the upper connecting ring 202, and the lower connecting ring 204 is connected to the base 1.

[0043] In this structure, the reflector 2 consists of an upper connecting ring 202, a conical portion 203, and a lower connecting ring 204. The reflective wall 201 is located on the outer wall of the upper connecting ring 202 and the conical portion 203. This structural design facilitates efficient and stable reflection of the light emitted by the LED beads 5, ensuring concentrated light emission. The upper connecting ring 202 is located inside the multiple LED beads 5 and is fixedly connected to the lamp plate 3. The outer diameter of the lower connecting ring 204 is larger than that of the upper connecting ring 202 and is connected to the base 1, making the connection between the reflector and the lamp plate and base stable, ensuring the stability of the overall structure of the warning light, and further optimizing the light reflection effect.

[0044] In some embodiments, such as Figure 6 and Figure 8 As shown, the reflector wall 201, upper connecting ring 202, conical part 203, and lower connecting ring 204 are designed as a single unit. This integrated design reduces assembly errors between components, ensures the overall strength and stability of the reflector, promotes consistent light reflection, and further enhances the light concentration effect and the reliability of the warning light.

[0045] In some embodiments, such as Figure 1 , Figure 4 and Figure 5As shown, a control button 6 is provided at the end of the lamp panel 3 facing the lamp cover 4. The control button 6 is used to control the opening or closing of the lamp beads 5. A spring-loaded pressure block 401 corresponding to the control button 6 is provided on the lamp cover 4. A through hole is provided at the position of the control button 6 on the lamp cover 4. The spring-loaded pressure block 401 is placed in the through hole and connected to the lamp cover 4 through a connecting thin wall. Since the spring-loaded pressure block 401, the connecting thin wall and the lamp cover 4 are a one-piece plastic component, the spring-loaded pressure block 401 has a certain degree of elasticity. This structure allows users to easily control the opening or closing of the lamp beads 5 by pressing the spring-loaded pressure block 401, making operation simple and convenient. At the same time, the lamp cover provides a certain degree of protection for the control button.

[0046] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the upper end of the reflector 2 is symmetrically provided with stepped holes 205, which are located on the upper connecting ring 202. The lamp cover 4 is symmetrically provided with first connecting posts 402 corresponding to the stepped holes 205. The first connecting posts 402 pass through the lamp plate 3 and are inserted into the stepped holes 205, and are fixedly connected to the reflector 2 by fasteners. The lamp plate 3 is symmetrically provided with through holes for the first connecting posts 402 to pass through. The lamp cover 4 is provided with multiple second connecting posts 403, which are fixedly connected to the lamp plate 3 by fasteners. The lamp plate 3 is provided with multiple through holes 301 for the fasteners to pass through. This connection method ensures a tight and stable connection between the lamp cover, lamp plate, and reflector, guaranteeing the reliability of the overall structure of the warning light. It also facilitates installation and debugging during production and assembly, and makes disassembly relatively convenient for later maintenance.

[0047] In some embodiments, such as Figure 7 and Figure 9 As shown, the base 1 and reflector 2 are engaged. The lower inner wall of the reflector 2 has multiple rotating slots 206 evenly spaced along the circumferential direction. These rotating slots 206 are located on the inner wall of the lower connecting ring 204. The base 1 has multiple locking heads 101 that can engage with the rotating slots 206. The inner side of the rotating slots 206 has limiting protrusions 207 to restrict the locking heads 101 from disengaging from the rotating slots 206, preventing the base 1 from accidentally opening. This engagement method not only facilitates the installation and removal of the base and reflector but also ensures the stability of the connection, preventing loosening during use.

[0048] In some embodiments, such as Figure 2 , Figure 4 and Figure 9As shown, a supporting flange 102 is provided on the base 1, and the lower end of the reflector 2 abuts against the supporting flange 102. Multiple reinforcing ribs 103 are evenly spaced along the circumference of the base 1, with one end of each reinforcing rib 103 connected to the supporting flange 102. This structure enhances the base's support for the reflector and the entire upper structure of the warning light, improving the overall stability of the warning light and enabling it to operate reliably in various operating environments.

[0049] In some embodiments, the lampshade 4 is made of transparent material. Using a transparent material minimizes light obstruction and absorption, ensuring that the concentrated light reflected by the reflector can be smoothly transmitted, thereby guaranteeing the effective illumination and warning function of the warning light.

[0051] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
