[0002] Traditional train lighting fixtures have a relatively large light panel area, and are arrayed with a large number of low-power lamp beads. This can avoid excessive light concentration, make the light uniform, have a good anti-glare effect, and significantly improve the heat dissipation of the lamp. The structure of common strip lights can refer to the Chinese invention patent application with publication number CN106949397A, entitled Strip Light. Due to the large light panel area of ​​the lamp, the large amount of plate material used, the high cost, and the large number of lamp beads, the probability of dead lights is greatly increased, and dark areas are easily generated, which needs to be improved. Utility Model Content

[0003] In order to solve the technical problems of existing rail transit lamps such as large lamp panel area, high cost and large number of lamp beads that are prone to lamp failure, the utility model provides a roof lamp structure with a lens for rail vehicle transportation.

[0008] Preferably, the clamping arm is provided with an opening for reducing the rigidity of the clamping arm. The bottom of the clamping arm is also provided with a groove for reducing the rigidity of the clamping arm.

[0009] By adopting the above technical solution: because the diffusion lens is small in size, the clamping arm is short in length, has high rigidity and poor elasticity, by setting the openings and grooves, the diffusion lens clamping arm is more flexible and can be more easily installed on the light board.

[0010] Preferably, a first support arm is provided on one side of the heat dissipation shell, a hemispherical groove is provided on the first support wall, a second support arm and a ball head are correspondingly provided on the lampshade, the ball head is embedded in the hemispherical groove, so that the first support arm and the second support arm are hinged; a first mounting plate is provided on the other side of the heat dissipation shell, a second mounting plate is correspondingly provided on the lampshade, and the first mounting plate and the second mounting plate are fixed by screws.

[0011] By adopting the above technical solution: one end of the lampshade is hinged and the other end is fixed by screws, which makes assembly very convenient and reduces the number of screws used.

[0012] Preferably, heat dissipation fins are provided on both sides of the heat dissipation housing.

[0013] By adopting the above technical solution: the heat dissipation area is increased to increase the heat dissipation capacity of the heat dissipation housing.

[0014] Preferably, the first mounting plate and the second mounting plate are fixed by screws and spring nuts.

[0015] By adopting the above technical solution: the present application adopts a reed nut, which is large in size and easier to grasp, and has a large screw hole, making it easier to insert and screw the screw, thereby improving the assembly efficiency of the lampshade.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The light board of this application is only equipped with one row of lamp beads, so the width of the light board is greatly reduced, the amount of plate material used is greatly reduced, thereby reducing the cost of the light board;

[0020] 2. The number of lamp beads is also greatly reduced, which reduces the probability of lamp failure exponentially;

[0021] 3. Each lamp bead is specially equipped with a diffusion lens, which can disperse the light emitted by the lamp bead and make the light even on the surface of the lampshade, thus better solving the problem of excessive concentration of light from a single row of lamp beads;

[0022] 4. The present application sets a long strip boss in the middle of the inner top wall of the heat dissipation shell, and the two sides of the lamp board extend beyond the two sides of the long strip boss, so that the two clamping arms of the diffusion lens can be directly clamped on the lamp board, which is very quick and convenient to install and has a low assembly cost.

DETAILED DESCRIPTION

[0034] The following is combined with Figures 1 to 10 This application is described in further detail.

[0035] Reference Figures 1 to 6 , the embodiment of the present application discloses a roof light structure with a lens for rail vehicle traffic, comprising a heat dissipation shell 1, a light board 2, a lampshade 3, a plurality of diffusion lenses 4 and a power supply (not shown). A long strip boss 11 is provided in the middle of the inner top wall of the heat dissipation shell 1, the light board 2 is arranged on the long strip boss 11, and the two sides of the light board 2 exceed the two sides of the long strip boss 11. A row of lamp beads 21 are provided on the light board 2, and each lamp bead 21 is configured with a diffusion lens 4. The diffusion lens 4 includes an optical part 41 and two symmetrically arranged clamping arms 42. The diffusion lens 4 is clamped on the light board 2 by two clamping arms 42, and the lampshade 3 is arranged at the lower end of the heat dissipation shell 1.

[0036] Only one row of lamp beads 21 is provided on the lamp board 2 of the present application, so that the width of the lamp board 2 is greatly reduced, and the amount of plate material used is greatly reduced, thereby reducing the cost of the lamp board 2. Of course, the power of a single lamp bead 21 needs to be appropriately increased; the number of lamp beads 21 is also greatly reduced, which reduces the probability of dead lamps exponentially; in addition, each lamp bead 21 is specially configured with a diffusion lens 4, which can disperse the light emitted by the lamp bead 21, so that the light is evenly emitted from the surface of the lampshade 3, thereby better solving the problem of excessive concentration of light from a single row of lamp beads 21; in order to more conveniently install the diffusion lens 4, the present application provides a long strip boss 11 in the middle of the inner top wall of the heat dissipation shell 1, and the two sides of the lamp board 2 extend beyond the two sides of the long strip boss 11, so that the two clamping arms 42 of the diffusion lens 4 can be directly clamped on the lamp board 2, and the installation is very quick and convenient, and the assembly cost is low.

[0037] Reference Figures 8 to 10 Two positioning posts 43 are provided at the bottom end of the optical portion 41, and corresponding positioning holes 22 are provided on the light board 2. The positioning posts 43 are inserted into the positioning holes 22 to better position the diffusion lens 4 and prevent the diffusion lens 4 from moving left and right.

[0038] Reference Figure 9 and Figure 10 The arm 42 is provided with an opening 421 and a groove 422 at the bottom thereof to reduce the rigidity of the arm 42. Since the diffuser lens 4 is small in size and the arm 42 is short in length, it has high rigidity but poor elasticity. By providing the opening 421 and the groove 422, the diffuser lens 4 arm 42 is more flexible and can be more easily mounted on the light board 2.

One end of the lampshade 3 is hinged and the other end is fixed by screws 5, which is very convenient to assemble and reduces the number of screws 5 used. The heat dissipation housing 1 is made of aluminum extrusion material, and the first arm 12 and the hemispherical groove 13 can be easily produced. The lampshade 3 is generally produced by injection molding, and the second arm 31 and the ball head 32 can also be easily produced.

[0040] Reference Figure 4 , heat dissipation fins 15 are provided on both sides of the heat dissipation housing 1 to increase the heat dissipation area and thus increase the heat dissipation capacity of the heat dissipation housing 1 .

[0041] Reference Figure 4 and Figure 5 The first mounting plate 14 and the second mounting plate 33 are fixed by screws 5 and spring nuts 6. Due to the blocking effect of the heat dissipation fins 15, it becomes difficult to install ordinary nuts. Therefore, the present application adopts spring nuts 6. The spring nuts 6 are larger and easier to grasp. The screw holes are larger, making it easier to insert and screw on the screws 5, thereby improving the assembly efficiency of the lampshade 3.

[0042] Reference Figure 6 The two end faces of the heat dissipation housing 1 are further provided with sealing plates 7 for sealing the space between the heat dissipation housing 1 and the lampshade 3 to prevent mosquitoes and dust from entering the space.
