Roof operating panel

Abstract

This invention discloses a roof-mounted control panel, including an electrically connected control circuit board and button assembly, and roof-mounted spotlights on both sides. Each spotlight includes LED beads, a spotlight lens, a clamping component, a planar lens, and a spotlight mounting housing. The LED beads are embedded in the LED bead slots of the spotlight lens. The spotlight lens is snapped into place with the clamping component, and the planar lens is positioned between the spotlight lens and the spotlight mounting housing. The spotlight lens is a single, integrated structure consisting of a lens body and an exiting part. The lens body is parabolic, and the axis of the lens body forms an angle α with the axis of the exiting part. While maintaining a similar height to existing hemispherical reflectors, the parabolic design allows for more focused but less concentrated light, thereby increasing the lumen output and brightness of the illuminated area. The incident surface within the LED bead slot is a slanted arc surface, and the oblique design of the spotlight lens ensures uniform light dispersion in the illuminated area, preventing excessive concentration. The combination of these two design elements effectively avoids the formation of light spots.

Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a roof-mounted control panel. Background Technology

[0002] When driving at night, it is difficult for passengers to see inside the vehicle, so roof-mounted lights are installed on the control panel for auxiliary lighting. To improve illumination, engineers designed the roof lights as spotlights. However, due to the limited space on the roof, existing spotlights mostly use hemispherical reflectors, which have a focusing effect. The light in the center is too concentrated, while the light in other parts is too diffuse, creating distinct inner and outer ring areas of light with light spots between them, affecting visibility. This needs improvement. Summary of the Invention

[0003] One of the technical problems to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a vehicle roof operation panel with a roof spotlight that has a good focusing effect, high brightness and no light spots.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: a roof-mounted operation panel, including a control circuit board and roof-mounted spotlights disposed on both sides of the button assembly. The roof-mounted spotlights include LED beads, spotlight lenses, clamping components, planar lenses, and spotlight mounting housings. The LED beads are mounted on the control circuit board and electrically connected. The light-emitting element of the LED bead is embedded in the LED bead groove at the upper end of the spotlight lens. The spotlight lens and the clamping component are rotated and assembled and then snapped together. The planar lens is disposed between the spotlight lens and the spotlight mounting housing. The spotlight mounting housing is fixed to the rear housing. The spotlight lens includes a lens body and an emission part with an integral solid structure. The lens body is parabolic in shape. The LED bead groove is disposed at the upper end of the lens body. The incident surface in the LED bead groove is a slanted arc surface and is coaxially disposed with the lens body. The axis of the lens body and the axis of the emission part have an angle α.

[0005] Compared with related technologies, this invention has the following advantages: the lens of the roof-mounted spotlight is an integrated lens body and an emission part. The lens body is designed as a solid parabola, and the axis of the lens body and the axis of the emission part have an angle α, that is, the spotlight lens is designed obliquely. With a height similar to that of the existing hemispherical reflector, the parabolic design can make the light more concentrated but not focused, thereby increasing the lumen of the illumination area and improving the brightness; the incident surface in the LED lamp bead slot is an oblique arc surface, and the oblique design of the spotlight lens makes the light in the illumination area diffuse evenly and not overly concentrated. The combination of the two can better avoid the formation of light spots; and the clamping component forms a tight fixing position for the spotlight lens and the plane lens, maintaining a stable lighting effect during vehicle vibration.

[0006] Preferably, the included angle α is 15°~45°.

[0007] Ideally, the included angle α is 20°~30°.

[0008] As an improvement, the exit surface of the exit section is composed of multi-faceted triangular surfaces. This is used to better eliminate dispersion and avoid the formation of light spots.

[0009] Preferably, the exit surface of the emission section is provided with a light-transmitting protective coating. This improves the light transmittance of the spotlight lens, increases brightness, and also provides protection and extends its lifespan.

[0010] As an improvement, a support ring is provided at the connection between the emission portion of the spotlight lens and the lens body. The clamping member includes an outer cylindrical body and an upwardly extending annular conical hollow support within the cylindrical body. The support ring rests on the upper end of the annular conical hollow support. When several lugs on the outer side of the support ring are engaged and fixed with corresponding rotating slots on the clamping member's cylindrical body, the bottom surface of the support ring abuts against the upper end of the annular conical hollow support. The emission portion of the spotlight lens is located in the hollow center of the annular conical hollow support. This ensures a stable connection between the spotlight lens and the clamping member.

[0011] As an improvement, the outer ring of the spotlight lens's support ring is connected to an upwardly extending support semi-ring, the top of which abuts against the control circuit board where the LED chips are mounted. This abutment between the spotlight lens and the control circuit board improves vibration resistance and maintains stable light output even under vibration.

[0012] As an improvement, the top of the supporting semi-ring is provided with two protruding posts, which are inserted into the control circuit board. This can limit the positional relationship between the spotlight lens and the LED beads, ensuring consistent light output while reducing assembly difficulty. Attached Figure Description

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] This preferred embodiment is as follows: Figures 1 to 4 The roof control panel shown includes a rear shell 1, a lower cover 2, a button assembly 3, a roof spotlight 4, a control circuit board 5, and a power connector (not shown in the figure). The rear shell 1 is provided with elastic buckles for fixing to the vehicle body. The lower cover 2 is connected and fixed to the rear shell 1 by multiple screws. The button assembly 3 is located in the middle of the lower cover 2. The button assembly 3 includes a central triangular warning light button 31 and spotlight switches 32 on both sides that control the lighting status of the roof spotlight 4 on the same side. The roof spotlight 4 is located on both sides of the button assembly 3. The roof spotlight 4 is fixed to the rear shell 1 by 2-3 screws. The control circuit board 5 is fixed to the rear shell 1 by screws and is electrically connected to the power connector.

[0026] In this embodiment, the roof spotlight 4 is as follows: Figure 4 and Figure 5As shown, the system includes a spotlight lens 41, LED beads 42, a clamping member 43, a plane lens 44, and a spotlight mounting housing 45. The pins of the LED beads 42 are soldered to the control circuit board 5 to form an electrical connection. The light-emitting body of the LED beads 42 is horizontally embedded in the LED bead groove 413 at the upper end of the spotlight lens 41. The spotlight lens 41 and the clamping member 43 are rotated and assembled and then snapped together. The plane lens 44 is disposed between the spotlight lens 41, the clamping member 43, and the spotlight mounting housing 45. The outer ring of the plane lens 44 has three upper edge latches with latching holes that engage with the protrusions on the outer side of the clamping member 43. The spotlight lens 41, the clamping member 43, and the plane lens 44 are installed into the stepped groove of the spotlight mounting housing 45. The connecting lugs on both sides of the spotlight mounting housing 45 are connected and fixed to the rear housing 1 by screws. Alternatively, the plane lens 44 may not have the outer ring latches and can be fixed by being pressed against the spotlight mounting housing 45 on both sides.

[0027] In this embodiment, the spotlight lens 41 is a concentrator made of a light-transmitting material, specifically as follows: Figures 6 to 8 As shown, the lens includes a lens body 411 and an exiting part 412, both of which are integral solid structures. An LED bead slot 413 is located at the top of the lens body 411. The LED bead slot 413 is wider at the top and narrower at the bottom, and the incident surface at the bottom of the LED bead slot 413 is a convex, obliquely curved surface. The axis of this incident surface is the same as the axis of the lens body 411. The lens body 411 is parabolic (its cross-sectional outer contour is parabolic). The exiting part 412 is a solid, arc-shaped structure that convexes downwards. An angle α is formed between the axis of the lens body 411 and the axis of the exiting part 412, with the angle α being 15° to 45°, preferably 20° to 30°. The exiting surface of the exiting part 412 is composed of multiple triangular facets, and can therefore also be called a prism layer. A light-transmitting protective coating 414 is provided on the exiting surface. This light-transmitting protective coating 414, made of a UV-curable material copolymerized from acrylate and siloxane, can increase the light transmittance of the spotlight lens 41 to greater than 95%. A radially protruding resting ring 415 is provided at the connection between the emission part 412 and the lens body 411. The resting ring 415 rests on the upper end of the annular conical hollow support of the clamping member 43. The emission part 412 is located in the hollow middle of the annular conical hollow support. When the three lugs 416 on the outer side of the resting ring 415 are engaged and fixed with the corresponding rotating slots on the cylinder of the clamping member 43, the bottom surface of the resting ring 415 abuts against the upper end of the annular conical hollow support. An upwardly extending support half-ring 417 is connected to the outer ring of the resting ring 415. The top end of the support half-ring 417 abuts against the control circuit board 5. The top end of the support half-ring 417 is also provided with two protrusions 418, which are inserted into and limited by the control circuit board 5.

[0028] In actual testing of the roof-mounted spotlight with an included angle α of 30°, the true color image is as follows: Figure 9 As shown, the core lighting area is bright and free of light spots.

[0029] 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.
