[0036] See also Figures 1 to 8 The utility model proposes a reading lamp and a vehicle using a diffusion lens, which can be used in the field of vehicle and indoor lighting, such as chandeliers, ceiling lamps, floor lamps, wall lamps, table lamps, downlights, spotlights, etc. In the utility model, by installing the reading lamp on the top of the driver's seat and the top of the middle of the back seat of the car, when the light in the car is insufficient, the reading lamp can provide sufficient brightness for the passengers to read in the car. The reading lamp of the utility model has uniform light and can meet the lighting function of a large area. It is described in detail through specific embodiments below.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of the utility model, the utility model proposes a reading lamp using a diffusion lens, which may include a rear cover 10, a light source circuit board 20, a diffusion lens 30, a panel 40 and a lampshade 50. The light source circuit board 20 may be connected to the rear cover 10, and a lighting lamp is provided on the light source circuit board 20. When the light source circuit board 20 is powered, the lighting lamp can be lit by the light source circuit board 20 to achieve lighting. The diffusion lens 30 is arranged on the irradiation side of the lighting lamp, and the diffusion lens 30 may be in a frustum shape as a whole, and the bottom end area of ​​the diffusion lens 30 is larger than the top end area of ​​the diffusion lens 30.

[0038] Specifically, the diffusion lens 30 may be in the shape of a truncated cone or a polygonal prism. The diffusion lens 30 is set in the shape of a truncated cone. The diffusion lens 30 can diffuse and evenly distribute the uneven light emitted by the lighting lamp, thereby satisfying the function of evenly distributing and diffusing the light over a large area. The panel 40 may be set on the side of the diffusion lens 30 away from the lighting lamp, and the panel 40 is connected to the rear cover 10, and the panel 40 can fix the position of the diffusion lens 30. The lampshade 50 may be connected to the panel 40, and the lampshade 50 plays a protective role on the panel 40. By changing the color of the lampshade 50, the light penetration of the lighting lamp can be changed, thereby bringing a soft feeling to the interior space of the vehicle and adding an intimate atmosphere.

[0039] Specifically, the bottom of the diffusion lens 30 may be provided with a plurality of circular patterns with the same center, and the distance between two adjacent circular patterns is 1.5 mm to 2.5 mm, so as to improve the light averaging and diffusion effect of the diffusion lens 30. The bottom of the diffusion lens 30 may be a plane or a curved surface, and the angle between the bottom plane or the bottom curved surface of the diffusion lens 30 and the generatrix of its side wall may be 60° to 75°.

[0040] See also Figure 2 and Figure 3 In one embodiment of the utility model, the light source circuit board 20 may be a printed circuit board (PCB). The formation process of the light source circuit board 20 may be as follows: after the printed circuit board is designed and manufactured (PCBA, Printed Circuit Board Assembly), various electronic components, integrated circuits, resistors, capacitors, connectors, etc. are installed on the PCB (Printed Circuit Board) through assembly processes such as surface mounting technology (SMT, Surface Mount Technology) or through-hole plug-in technology (Through-Hole Insertion, DIP: Dual In-line Package), and are formed through processes such as welding.

[0041] See also Figure 2 and Figure 3 In one embodiment of the utility model, in an optical system, a diffusion lens 30 is often used to adjust the light path or change the direction of a light beam. The diffusion lens 30 uses the principle of reflection or refraction to achieve deflection, for example, using a free-form surface lens, a prism combination or a microlens array. In light-emitting diode (LED) lighting, the diffusion lens 30 can achieve a beam distribution at a specific angle. The diffusion lens 30 deflects the light beam emitted by the LED light source, and the diffusion lens 30 converts a light beam with a specific directionality into a nearly uniformly divergent light beam.

[0042] See also Figure 2 and Figure 3 In one embodiment of the utility model, a reflective bowl 410 is connected to the panel 40. The reflective bowl 410 is arranged on the side of the diffusion lens 30 away from the lighting lamp. The reflective bowl 410 uses the reflective structure on its surface to project the light emitted by the lighting lamp to the outside in a predetermined shape or pattern. The structural advantage of the reflective bowl 410 is that the reflection efficiency is very high, which can be compared with the reflection efficiency of a mirror, so high-brightness lighting can be achieved to a certain extent. The panel 40 and the reflective bowl 410 can be designed in an integrated manner, which fully saves the number of parts and assembly complexity, saves mold costs, and reduces assembly costs.

[0043] See also Figure 2 and Figure 4 In one embodiment of the utility model, the reading lamp further includes a push switch 60, which passes through the lampshade 50 and can be electrically connected to the light source circuit board 20. The lighting lamp on the light source circuit board 20 can be controlled by pressing the switch 60. The push switch 60 is arranged at a side position of the diffusion lens 30, which will not affect the diffusion and uniform light effect of the diffusion lens 30 on the lighting lamp. The lampshade 50 can be connected with a decorative part 510, which can be formed by electroplating or painting process, and can play a role in aesthetics.

[0045] Specifically, the bottom area of ​​the frustum portion 320 is larger than the top area of ​​the frustum portion 320, and the frustum portion 320 may be a truncated cone or a polygonal truncated cone. The input portion 310 diffuses and evens out the uneven light emitted by the lighting lamp, so that the light has the function of large-area evenness and diffusion. Figure 5 As shown, the frustum portion 320 can further even out and diffuse the light of the input portion 310. The convex portion 330 can protrude toward the side away from the light source circuit board 20, and the surface of the convex portion 330 can be in a curved shape. The convex portion 330 can further diffuse the light of the input portion 310 and the frustum portion 320. The convex portion 330 diffuses the scale-like light generated by the frustum portion 320 to prevent the generation of scale-like lines. The bottom radius of the frustum portion 320 can be 10 cm, and the thickness of the convex portion 330 can be 2.2 cm.
