A lens structure for a warning light

Abstract

This utility model relates to the field of warning light technology, specifically a lens structure for a warning light, including a lens and a circuit board with a light source. The bottom of the lens has a protrusion assembly corresponding to the light source. Each protrusion assembly includes two truncated cones and a long strip platform located between the two truncated cones. Multiple truncated cones are provided at the bottom of the long strip platform, and a groove is provided at the top of the lens. The groove corresponds to a protrusion of shape, which is strip-shaped. The groove also corresponds to a protrusion of shape, which is composed of a semi-circular protrusion and a semi-strip-shaped protrusion. Therefore, by setting protrusions and adapting them to the truncated cones and the long strip platform, circular and strip-shaped light spots can be matched. Thus, when a high central light intensity but a small illumination range is required, a light source matched with protrusion 2 can be used alone; similarly, when a low central light intensity but a large illumination range is required, a light source matched with protrusion 1 can be used alone.

Description

Technical Field

[0001] This utility model relates to the field of warning light technology, and specifically to a lens structure for warning lights. Background Technology

[0002] Warning lights are devices that use light signals to indicate danger. They are widely used in transportation, industry, construction, and other fields, conveying warning information through different colors and flashing frequencies. Furthermore, different regions around the world have different standards for warning light products. Some require high central light intensity (high illumination) but a small warning range (small illumination area), thus using a circular light spot (high central light intensity but small illumination area). Others require low central light intensity but a large warning range, thus using a striped light spot (large illumination area but low central light intensity). Therefore, there are two different lens structures to correspond to these two drastically different standards. The question then becomes: how can both of these different standards be satisfied within a single lens? Summary of the Invention

[0003] The purpose of this invention is to provide a lens structure for warning lights. By setting protrusion one and protrusion two, and adapting to truncated cone one, truncated cone two, and elongated platform, a circular light spot and a strip light spot can be matched. Thus, while satisfying the requirement of high light intensity, it also has a large illumination range. Therefore, when a high central light intensity but a small illumination range is required, the light source matched with protrusion two can be lit alone. Similarly, when a low central light intensity but a large illumination range is required, the light source matched with protrusion one can be lit alone.

[0037] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0038] like Figures 1-7 As shown, a lens structure for a warning light includes a circuit board 1 and a lens 2. The circuit board 1 has at least one light source 11, and the bottom of the lens 2 has at least one set of boss components corresponding to the light source 11. Each set of boss components includes a long strip platform 25 and two truncated cones 21. The long strip platform 25 is located between the two truncated cones 21, and the bottom of the long strip platform 25 has multiple truncated cones 22. The top of the lens 2 has a groove.

[0039] Meanwhile, the first groove is provided with a protrusion 23 corresponding to the second frustum 22. The protrusion 23 is strip-shaped and adapted to the single light source 11. The protrusion 23 protrudes outward in the direction away from the light source 11. The second frustum 22 is provided with an inwardly recessed arc surface 221 on the side near the light source 11. Secondly, the first groove is provided with a protrusion 24 corresponding to the first frustum 21. The protrusion 24 is composed of a half-circular protrusion and a half-strip protrusion. The protrusion 24 is adapted to the single light source 11. The protrusion 24 protrudes outward in the direction away from the light source 11. The first frustum 21 is provided with an outwardly protruding arc surface 211 on the side near the light source 11.

[0040] Therefore, in practical use, by setting protrusion 1 23 and protrusion 24, and adapting them to frustum 1 21, frustum 22, and elongated platform 25, circular and strip light spots can be matched. This achieves both high light intensity and a large illumination range. Specifically, protrusion 1 23, protrusion 24, and elongated platform 25 can be used to form strip light spots, while protrusion 24, frustum 1 21, and frustum 22 can be used to form circular light spots. Thus, when a high central light intensity but a small illumination range is required, a light source adapted to protrusion 2 can be used alone; similarly, when a low central light intensity but a large illumination range is required, a light source adapted to protrusion 1 can be used alone.

[0041] Moreover, the number of boss components can be selected according to the actual situation. For example, the bottom of the lens 2 of this application is provided with three sets of boss components corresponding to the light source 11, and both ends of the long strip platform 25 are arc surfaces three, and the arc surfaces three are adapted to the outer surface of the round frustum 21.

[0042] like Figures 1-7 As shown, at least one step 26 is provided on the outside of protrusion 23 and protrusion 24, and the height of the top of protrusion 24 is higher than or equal to the height of the top of protrusion 23 and lower than the height of step 26.

[0043] Therefore, in actual use, the step 26 is designed to be both aesthetically pleasing and to allow light to converge towards the center.

[0044] Furthermore, the truncated cone 21 has a groove 212 on the side near the light source 11, and the bottom surface of the groove 212 is an arc surface 211, and the side surface of the groove 212 is an inclined surface, and the diameter of the groove 212 gradually increases along the direction near the light source.

[0045] Meanwhile, the second truncated cone 22 has a groove 3 223 on the side near the light source 11, and the bottom surface of the groove 3 223 is an arc surface 221, and the four sides of the groove 3 223 are inclined surfaces, and the diameter of the groove 3 223 gradually increases along the direction near the light source.

[0046] Therefore, in actual use, the aperture gradually increases along the direction closer to the light source and gradually decreases along the direction away from the light source, thereby guiding and converging the light.

[0047] like Figures 1-7 As shown, it also includes a mounting bracket 3, which has a placement slot 31. The placement slot 31 houses the circuit board 1, and the lens 2 is located above the circuit board 1. The lens 2, the circuit board 1, and the mounting bracket 3 are connected by fasteners. The fasteners are screws, which pass through the mounting bracket 3 and the circuit board 1 and connect to the mounting portion 27 of the lens 2. The bottom of the placement slot 31 has an opening to facilitate the passage of wires, etc.

[0048] Meanwhile, the structure related to lens 2 is as follows: First, mounting portions 27 are provided on both sides of the bottom of lens 2, and the bottom of the mounting portion 27 is provided with a protruding plate 271 that abuts against the bottom surface of the placement groove 31, and the circuit board 1 is located between two protruding plates 271. Therefore, in actual use, the position of the circuit board 1 is limited by the protruding plates 271. Moreover, there can be four protruding plates 271, so as to improve the limiting effect.

[0049] Secondly, mounting strips 10 are provided on both sides of the lens 2 in the placement groove 31, and protrusions 101 are provided at both ends of the mounting strips 10. Furthermore, an abutment surface is provided on the bottom of the lens 2 outside the frustum 21, and the abutment surface abuts against the protrusions 101. Therefore, in actual use, the position of the lens 2 is limited by the mounting strips 10.

[0050] Furthermore, a connecting post 28 is provided at the bottom of the lens 2, and a snap-fit ​​hole 13 is provided at the bottom of the circuit board 1 corresponding to the connecting post 28. Therefore, in actual use, the lens 2 and the circuit board 1 are connected by the matching of the connecting post 28 and the snap-fit ​​hole 13, which also limits the position between the two.

[0051] Furthermore, a backing plate 9 is provided between the circuit board 1 and the mounting bracket 3. The backing plate 9 is used to shield the internal structure and thus protect it. The backing plate 9 also has openings to facilitate the passage of wires and other components. Moreover, the screws that pass through the circuit board 1 also pass through the backing plate 9.

[0052] like Figures 1-7 As shown, it also includes a mounting bracket 3 and a lampshade 4, and the lampshade 4 is connected to the mounting bracket 3 and a lens 2 and a circuit board 1 are disposed between the two, and the mounting bracket 3 is provided with buckles 35 on both sides.

[0053] The structure between the lampshade 4 and the mounting bracket 3 is as follows: First, the bottom of the lampshade 4 is provided with a protruding strip 41, and the mounting bracket 3 is provided with a snap-fit ​​groove 34 corresponding to the protruding strip 41. The connection is achieved by the fitting of the protruding strip 41 and the snap-fit ​​groove 34. Moreover, after the lampshade 4 and the mounting bracket 3 are installed, they form a whole, namely a lighting assembly, which facilitates the installation of the warning light.

[0054] This utility model also includes a connecting frame 5 and a housing 6. The connecting frame 5 has a mounting hole 51 in the middle and a baffle 512 is provided inside the mounting hole 51. The connecting frame 5 is connected to the component where the warning light needs to be installed by fasteners. The mounting frame 3 is located inside the mounting hole 51 and on the baffle 512. The inner wall of the mounting hole 51 has a snap-fit ​​groove 511 corresponding to the snap fastener 35. The housing 6 is sleeved on the outside of the connecting frame 5 and is located outside the contact point between the lamp cover 4 and the connecting frame 5. The fasteners are screws.

[0055] Therefore, in actual use, the connection can be achieved by the matching of the second buckle 35 and the second snap-fit ​​groove 511, and the baffle 512 can limit the movement. Moreover, the overall installation involves first installing the connecting bracket 5, that is, installing the connecting bracket 5 on the part where the warning light needs to be installed, and then connecting the light assembly (i.e., lamp cover 4, lens 2, circuit board 1 and mounting bracket 3) to the connecting bracket 5, and then covering it with the outer shell 6. This way, the connection between the connecting bracket 5 and the part where the warning light needs to be installed is built into the outer shell 6, which has a better appearance and prevents it from being disassembled by others. It can also protect the connection between the connecting bracket 5 and the part where the warning light needs to be installed.

[0056] Furthermore, the structure between the connecting frame 5 and the outer casing 6 is as follows: Firstly, a latch 61 is provided on the inner wall of the outer casing 6, and a corresponding engaging groove 54 is provided on the outer side of the connecting frame 5. Therefore, in actual use, the connection is achieved by the fitting of the latch 61 and the engaging groove 54.

[0057] Meanwhile, the bottom of the connecting frame 5 is provided with a base plate 8, and the fasteners pass through the connecting frame 5 and the base plate 8 in sequence to connect with the parts that need to install warning lights. The top of the base plate 8 is provided with a protrusion 3 81, and the connector 56 is provided with a snap-fit ​​groove 1 56 corresponding to the protrusion 3 81. The bottom of the outer shell 6 abuts against the bottom of the base plate 8.

[0058] The base plate 8 is made of rubber, and the fasteners are screws. Therefore, in actual use, the base plate 8 can be used to fit against the parts where warning lights need to be installed, thereby strengthening the connection and protecting the parts where warning lights need to be installed. Furthermore, the base plate 8 has drainage grooves to facilitate water flow and prevent water accumulation, and the protrusion 81 can be slotted to reduce its size.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
