Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, specifically to a lens and a lamp. Background Technology

[0002] Lighting fixtures are a general term for lighting tools, and there are many types, such as indicator lights. When indicator lights are used to indicate direction, they can also be called arrow lights. Arrow lights consist of a base, a lens, and a circuit board located between the base and the lens, with the light source mounted on the circuit board. The lens is an optical element made of a transparent material such as glass or crystal, and it has an inwardly concave curved surface. Light diffuses outward through this curved surface, so each light source in an arrow light lens has an inwardly concave curved surface. However, in existing arrow lights, the light source forms a circular light spot after passing through the curved surface. Since an arrow light is a relatively long and narrow fixture, using conventional lenses would require a large number to meet the required illumination length, thus increasing costs. Furthermore, each lens would require multiple curved surfaces, making manufacturing more complicated. Summary of the Invention

[0003] The purpose of this invention is to provide a lens and a lamp that, by setting the left and right sides of the boss as planes and the distance difference, and by adapting the protruding strip, changes the light path and makes the light spot change from a circle to an ellipse, which is longer horizontally and shorter vertically. Therefore, for the same length, the number of lamp sources and bosses required for the elliptical light spot is less, thus reducing the cost and making the lens manufacturing relatively simple. This solves the problem that the existing circular light spot requires a large number of lamp sources and bosses.

[0004] The purpose of this utility model is achieved as follows:

[0005] A lens includes a main body, and at least one protrusion is provided on the bottom of the main body. The side of the protrusion away from the main body is an outwardly convex arc surface one, and the arc surface one is provided with at least one convex strip. A groove is formed on the side of the protrusion away from the main body, and the bottom surface of the groove one is an inwardly concave arc surface two. The left and right sides of the protrusion are formed with planes, and the convex strip is arranged parallel to the planes. The distance between the left and right sides of the protrusion is less than the distance between the upper and lower sides of the protrusion.

[0006] Preferably, the side of the protrusion away from the main body is an outwardly convex arc surface three, and there is a groove two between two adjacent protrusions, and the bottom surface of the groove two is an inwardly concave arc surface four.

[0007] Preferably, the main body includes a base plate and a side plate, and the bottom of the base plate and the inner wall of the side plate form an installation groove, and the installation groove has a boss inside. The side plate has a protruding edge on its outer side, and the bottom of the protruding edge has a snap-fit ​​plate for connecting with the base.

[0008] A lamp includes a base and a lens as described in any of the above claims, wherein a circuit board is disposed between the base and the main body, and a light source is disposed on the corresponding boss of the circuit board.

[0009] Preferably, there are three circuit boards, two of which are arranged at an angle and combined to form a V-shape, and these two circuit boards are circuit board one and circuit board two, respectively;

[0010] The first circuit board has a sloping surface 1 formed on the side near the second circuit board, and the first circuit board has a step 1 and a step 2 respectively at both ends of the sloping surface 1. The second circuit board has a sloping surface 2 formed corresponding to the sloping surface 1, and the second circuit board has a step 3 at one end of the sloping surface 2. When the sloping surface 1 and the sloping surface 2 are matched, the step 1 abuts against one side of the second circuit board, and the step 2 abuts against the step 3.

[0011] Preferably, the base has a slot on the side near the main body that is adapted to the snap-fit ​​plate;

[0012] Or / and, the base is provided with a hollow connecting column one on the side near the main body, and there is at least one connecting column one, and a protruding plate is provided at the end of the connecting column one near the main body. The main body is provided with a connecting column two on the side near the base, and there is at least one connecting column two with a connecting groove one. The connecting column two has a connecting groove two communicating with the connecting groove one at the end near the base, and the protruding plate is located in the connecting groove two.

[0013] Preferably, the base has a limiting plate on the side near the main body, and the bottom of the circuit board abuts against the limiting plate, and the bottom of the circuit board is connected to the base by fasteners.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention alters the light path by using flat surfaces on both sides of the boss and the distance difference between them, along with the fitting of a protruding strip, thus changing the light spot from a circle to an ellipse. Specifically, the ellipse is longer horizontally than vertically. Therefore, for the same length, an elliptical light spot requires fewer light sources and bosses, resulting in reduced costs and simpler lens manufacturing. Simultaneously, the curved surface acts as a focusing element, increasing the light spot intensity. Attached Figure Description

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-8 As shown, a lens includes a main body 1, and at least one protrusion 11 is provided on the bottom of the main body 1. The side of the protrusion 11 away from the main body 1 is an outwardly convex arc surface, and the arc surface is provided with at least one protruding strip 111. At the same time, a groove 112 is formed on the side of the protrusion 11 away from the main body 1, and the bottom surface of the groove 112 is an inwardly concave arc surface. Furthermore, planes 113 are formed on the left and right sides of the protrusion 11, and the protruding strip 111 is parallel to the planes 113. The distance between the left and right sides of the protrusion 11 is less than the distance between the top and bottom sides of the protrusion 11.

[0032] Therefore, in practical use, by setting the left and right sides of the boss 11 as planes 113 and the distance difference, and by adapting the protrusion 111, the light path is changed, thus changing the light spot from a circle to an ellipse. This ellipse is longer horizontally and shorter vertically. Therefore, for the same length, the number of lamp sources 31 and bosses 11 required for an elliptical light spot is less, resulting in reduced costs and relatively simpler lens manufacturing. Simultaneously, the curved surface 1 acts as a focusing element, thereby increasing the light spot intensity.

[0033] Meanwhile, the side of the protrusion 111 away from the main body 1 is an outwardly convex arc surface three, and between two adjacent protrusions 111 is a groove two 114, and the bottom surface of the groove two 114 is an inwardly concave arc surface four. Therefore, in actual use, the concave and convex design makes the light refraction effect better.

[0034] like Figures 1-8 As shown, the main body 1 includes a base plate 12 and a side plate 13. The bottom of the base plate 12 and the inner wall of the side plate 13 form a mounting groove 14, and the mounting groove 14 has a protrusion 11 inside. The side plate 13 has a protruding edge 131 on its outer side, and the bottom of the protruding edge 131 has a snap-fit ​​plate 132 for connecting with the base 2. Therefore, in actual use, the main body 1 is connected to the base 2 through the snap-fit ​​plate 132.

[0035] This utility model also protects a lamp, including a base 2 and a lens as described in any of the above claims, and a circuit board is provided between the base 2 and the main body 1, and a light source 31 is provided on the circuit board corresponding to the protrusion 11, and a slot 21 adapted to the snap-fit ​​plate 132 is provided on the side of the base 2 near the main body 1.

[0036] There are three circuit boards, two of which are tilted and combined to form a V-shape. These two circuit boards are circuit board one 32 and circuit board two 33.

[0037] Meanwhile, the structure between circuit board 1 32 and circuit board 2 33 is as follows: First, circuit board 1 32 has a slope 1 321 formed on the side close to circuit board 2 33, and circuit board 1 32 has a step 1 322 and a step 2 323 respectively at both ends of the slope 1 321. Circuit board 2 33 has a slope 2 331 formed corresponding to the slope 1 321, and circuit board 2 33 has a step 3 332 at one end of the slope 2 331.

[0038] Therefore, in actual use, when inclined plane 1 321 and inclined plane 2 331 are matched, step 1 322 abuts against one side of circuit board 2 33, and step 2 323 abuts against step 3 332.

[0039] Moreover, the structure between the circuit board and the base 2 is as follows: First, the base 2 has a limiting plate 23 on the side close to the main body 1, and the bottom of the circuit board abuts against the limiting plate 23, and the bottom of the circuit board is connected to the base 2 by fasteners.

[0040] The fasteners are screws, and the base 2 is provided with a hollow mounting post 24. The screw passes through the circuit board and connects to the mounting post 24. At the same time, the circuit board can also be adapted to the connecting post 22 mentioned below, and the circuit board is sleeved on the outside of the protrusion 221 and then fastened with screws.

[0041] like Figures 1-8 As shown, the base 2 and the main body 1 are also connected by screws, and the relevant structure is as follows: First, the base 2 is provided with a hollow connecting post 22 on the side near the main body 1, and there is at least one connecting post 22. The connecting post 22 is provided with a protruding plate 221 at the end near the main body 1. At the same time, the main body 1 is provided with a connecting post 15 on the side near the base 2, and there is at least one connecting post 15 and a connecting groove 151 is provided. The connecting post 15 is provided with a connecting groove 152 communicating with the connecting groove 151 at the end near the base 2.

[0042] Therefore, in actual use, the convex plate 221 is located in the connecting groove 152, thereby achieving initial positioning. At this time, one end of the screw passes through the base 2 and is located in the connecting groove 151, thereby connecting with the connecting groove 151, and thus realizing the connection between the base 2 and the main body 1.

[0043] Furthermore, screws can be used to mount the lamp on other components.

[0044] 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.
