[0002] In the field of simulation racing, with the advancement of technology, the simulation degree and user experience of simulation racing steering wheels have become the focus of research and development.

[0003] Since simulation racing steering wheels are generally used in indoor scenes, relevant light sources need to be configured on the steering wheels to prompt the status of relevant functions, so as to avoid users being unable to understand the status of relevant functions in a dim indoor environment. However, the light source design of existing simulation racing steering wheels is generally realized directly using LEDs and light shielding sheets, which has the disadvantages of glare and uneven and soft distribution of the light source. After long-term use, it is easy to cause discomfort and fatigue to the user's eyes.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0032] First, please refer to Figure 1 Some embodiments of the present application provide a lighting assembly for use in a simulated racing steering wheel. The lighting assembly includes an LED light board 1, a light blocking member 2, a light homogenizing film 3 and a light transparent plate 4 arranged in sequence from bottom to top. The light blocking member 2 has a plurality of first through holes 21 enclosing the LED lamp beads on the LED light board 1. The light homogenizing film 3 and the light transparent plate 4 cover all the first through holes 21.

[0033] Specifically, the light blocking member 2 is an opaque workpiece, and the first through hole 21 thereon is used to limit the light diffusion direction of the LED lamp beads on the LED light board 1. In the embodiment of the present application, the light blocking member 2 is preferably a plastic member, and its bottom surface is in contact with the LED light board 1. The LED lamp beads are mounted on the board surface of the LED light board 1, and can be located below the first through hole 21 or in the first through hole 21, preferably in the first through hole 21. There is at least one LED lamp bead in each first through hole 21. The LED lamp beads surrounded by different first through holes 21 can be used to indicate switches with different functions or different gears of a certain type of function on the simulated racing steering wheel.

[0034] More specifically, the light emitted by the LED lamp bead located in the first through hole 21 diffuses upward along the first through hole 21, and the light homogenizing film 3 that completely covers the first through hole 21 can adjust the refractive index and reflectivity of the light from the first through hole 21, so as to effectively distribute the light evenly and reduce the unevenness of the light during the propagation process, so that the light is evenly distributed within the mapping range of the first through hole 21 on the light homogenizing film 3 and then diffuses outward, thereby processing the point light source into a block light source 7 of the size of the first through hole 21 (in order to clearly mark the location of the block light source 7, Figure 3 and Figure 4 The block light source 7 is added to the transparent plate to show the schematic position), which improves the visual effect of the product, reduces reflection and glare, and effectively reduces user eye discomfort and fatigue.

[0035] More specifically, the light homogenizing film 3 is disposed between the light blocking member 2 and the light transparent plate 4, which can effectively ensure the flatness of the light homogenizing film 3 and protect the surface of the light homogenizing film 3, thereby improving the durability of the product.

[0036] More specifically, the light-transmitting plate 4 can be made of various light-transmitting materials. In the embodiment of the present application, a light-transmitting acrylic plate is preferred. The light-transmitting acrylic plate has the characteristics of low manufacturing cost, high transparency and strong impact resistance. It can be made into a visible light-transmitting form and can also be made into a light-transmitting form of different colors according to usage requirements.

[0037] More specifically, different silk-screen textures can be added to the surface of the light-transmitting plate 4 according to usage requirements, so that the lighting assembly of the embodiment of the present application can produce different lighting effects.

[0038] It should be noted that the lighting assembly of the embodiment of the present application is installed on a simulated racing steering wheel, which can be installed by fixing the light blocking member 2 and the LED light board 1 on the simulated racing steering wheel, such as fixing the light blocking member 2 on the outer shell of the simulated racing steering wheel and fixing the LED light board 1 inside the simulated racing steering wheel by snapping, gluing or bolting; the uniform light film 3 can be glued and fixed on the surface of the light blocking member 2 or clamped and fixed based on the light blocking member 2 and the light-transmitting plate 4.

[0039] The lighting assembly of the embodiment of the present application is applied to a simulated racing steering wheel to realize the lighting function based on the LED light board 1, the light blocking member 2, the light homogenizing film 3 and the light transparent plate 4 arranged in sequence, so as to cooperate with the first through hole 21 set to enclose the LED lamp beads and the light homogenizing film 3 covering the first through hole 21 to convert the point light source into a block light source 7, and then emit light to the simulated racing steering wheel based on the light transparent plate 4 with high light transmittance, which can effectively reduce the user's eye discomfort and fatigue, thereby improving the visual effect of the product, and the light transparent plate 4 and the light blocking member 2 can cooperate to limit the setting position of the light homogenizing film 3 and effectively protect the light homogenizing film 3.

[0040] In some preferred embodiments, the top of the light blocking member 2 has a limiting convex edge 22 , and the light homogenizing film 3 and the light-transmitting plate 4 are both installed in the limiting convex edge 22 .

[0041] Specifically, the limiting convex edge 22 can form a mounting groove on the surface of the light blocking member 2 for limiting the mounting position of the light homogenizing film 3 and the light transmitting plate 4, which is beneficial to the installation and positioning of the light homogenizing film 3 and the light transmitting plate 4 for easy assembly of the product.

[0042] In some preferred embodiments, the outer side of the light-transmitting plate 4 fits with the inner side of the limiting convex edge 22 , which can prevent dust from entering between the light-blocking member 2 and the light-transmitting plate 4 and contaminating the light-homogenizing film 3 .

[0043] More specifically, the light-transmitting plate 4 can be fixed on the limiting convex edge 22 by means of bonding or interference fit.

[0044] In some preferred embodiments, the top surface of the limiting convex edge 22 is higher than the top surface of the light-transmitting plate 4 , which can effectively limit the installation position of the light-transmitting plate 4 and prevent the light-transmitting plate 4 from falling off.

[0045] In some preferred embodiments, the edge of the light homogenizing film 3 partially contacts the limiting convex edge 22 .

[0046] Specifically, Figure 1 As shown, the light-homogenizing film 3 has multiple recessed portions 31 at its edge, and the protruding portions 32 on its edge abut against the inner wall of the limiting convex edge 22. The light-homogenizing film 3 adopts this structure to save the material of the light-homogenizing film 3, and its installation position in the limiting convex edge 22 can be limited by the protruding portions 32, and the recessed portions 31 are conducive to workers holding the light-homogenizing film 3 to accurately align the light-homogenizing film 3 and cover it on the light blocking member 2.

[0047] Second, please refer to Figure 2 and Figure 3 Some embodiments of the present application also provide a knob lamp for use in a simulated racing steering wheel. The knob lamp includes a lighting assembly, a band switch 5 and a knob cover 6 as provided in the first aspect. The rotating axis of the band switch 5 passes through the LED light board 1, the light blocking member 2, the light uniforming film 3 and the light transparent plate 4. The knob cover 6 is fixed on the rotating axis and is located above the light transparent plate 4. The LED lamp beads on the LED light board 1 include a plurality of first lamp beads 11 arranged in a circular array based on the rotating axis. The light blocking member 2 is configured with a first through hole 21 corresponding to each first lamp bead 11.

[0048] Specifically, the band switch 5 is a circuit device used to switch bands or select different circuits, which includes a mounting end and a control end. The band switch 5 in the embodiment of the present application is a rotary band switch, whose control end is a rotating shaft, and whose mounting end is fixed on the circuit board inside the simulated racing car steering wheel.

[0049] More specifically, the knob light of the embodiment of the present application is used to indicate different gears of a certain type of function, such as the gear of one of DIFF (Differential), ABS (Antilock Brake System), TC (Traction Control System), and MAP (Throttle / Pedal Map); when indicating different gears, the LED light board 1 in the knob light can indicate different gears by turning on different numbers of first lamp beads 11 or making the first lamp beads 11 produce different light effects; in a dim environment using a simulated racing steering wheel, the knob light can intuitively prompt the user of the current gear of the relevant function.

[0050] More specifically, in this embodiment, the LED light board 1, the light blocking member 2, the light uniforming film 3 and the light transparent plate 4 all have a coaxially arranged second through hole in the center, and the rotating axis of the band switch 5 passes through the second through hole to penetrate the LED light board 1, the light blocking member 2, the light uniforming film 3 and the light transparent plate 4.

[0051] More specifically, the second through hole is a circular hole, the diameter of which is larger than the diameter of the rotation axis of the band switch 5 , so as to ensure that the band switch 5 can rotate freely in the second through hole.

[0052] More specifically, in this embodiment, the first through holes 21 corresponding to the first lamp beads 11 are also arranged in a circular array based on the rotation axis.

[0054] In some preferred embodiments, the bottom of the knob cover 6 has a limiting step 61 .

[0055] Specifically, the bottom of the limiting step 61 is in contact with the top surface of the light-transmitting plate 4 to limit the installation position of the knob cover 6 on the band switch 5 .

[0056] More specifically, in this embodiment, the limiting step 61 partially covers the first through hole 21 configured corresponding to the first lamp bead 11, and the limiting step 61 has an identification structure for indicating the current gear position of the relevant function, such as an indicating scale, an indicating protrusion, etc.

[0057] In some preferred embodiments, the limiting step 61 has a notch 62 for indicating the gear position.

[0058] Specifically, in this embodiment, the knob lamp of the embodiment of the present application indicates the current gear position of the relevant function based on the positional relationship between the notch 62 and the first lamp bead 11. In the embodiment where the limiting step 61 partially covers the first through hole 21 corresponding to the first lamp bead 11, the block light source 7 generated by the first through hole 21 corresponding to the notch 62 is completely exposed so that the user can view the complete block light source 7, which is conducive to the user's quick identification of the current gear position.

[0059] In some preferred embodiments, the first through hole 21 corresponding to the first lamp bead 11 has a fan-shaped or trapezoidal shape.

[0060] Specifically, in the embodiment of the present application, the shape of the first through hole 21 corresponding to the first lamp bead 11 is preferably a fan-shaped shape, which can fully utilize the layout space of the knob lamp to configure the block light sources 7 with clear intervals.

[0061] More specifically, the inner corners of the first through holes 21 configured corresponding to the first lamp beads 11 are rounded.
