Description

Technical Field

[0001] This invention belongs to the field of mahjong machine technology, and specifically relates to a mahjong machine with a controllable lighting. Background Technology

[0002] Mahjong machines, as high-end leisure equipment that integrates entertainment and social functions, have become an indispensable supporting facility in various settings such as homes, hotels, and leisure clubs due to their outstanding advantages such as convenient operation, fair shuffling, and comfortable user experience.

[0003] Currently, the lighting needs of mahjong machines during daily use mostly rely on conventional lighting fixtures provided in leisure and entertainment venues. However, these fixtures are generally far from the mahjong table, resulting in significant light attenuation during propagation. Furthermore, due to limitations in the installation angle and light scattering range of the fixtures, it is difficult to create a uniform and sufficient effective lighting area on the mahjong table. This deficiency directly leads to problems such as blurred vision and difficulty in distinguishing details when users identify mahjong tiles. This has a particularly significant impact on elderly users with relatively weak eyesight, severely reducing the leisure and entertainment experience of playing mahjong. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a mahjong machine with controllable lighting. The technical problem to be solved by this invention is: how to form an effective light zone on the mahjong tiles to enhance the user's recognition of the mahjong tiles and improve the user experience.

[0005] The above-mentioned technical objective of the present invention can be achieved through the following technical solution: a mahjong machine with controllable lighting, comprising a mahjong machine body, wherein illumination light strips are rotatably arranged on all four sides of the mahjong machine body, and placement areas for placing mahjong tiles are provided on all four sides of the mahjong machine body, wherein the beam of the illumination light strips is obliquely directed from bottom to top toward the mahjong tiles in the corresponding placement areas, wherein a controller is provided on the mahjong machine body, and human body sensing modules are provided on all four sides of the mahjong machine body, wherein the human body sensing modules are electrically connected to the controller, and the controller is electrically connected to the illumination light strips, wherein when the human body sensing module senses a human body, the controller controls the corresponding illumination light strip to turn on, and wherein adjustment knobs for adjusting the brightness of the corresponding illumination light strips are provided on all four sides of the mahjong machine body.

[0006] In the aforementioned mahjong machine with controllable lighting, the main body of the mahjong machine has strip-shaped grooves on all four sides for vertically placing mahjong tiles. The strip-shaped grooves are the placement areas, and the light beams of the illumination strips cover and are completely located within the strip-shaped grooves.

[0007] In the aforementioned mahjong machine with controllable lighting, the bottom of the strip groove is inclined from low to high from the side closest to the center of the mahjong machine body to the side furthest from the center of the mahjong machine body, and the inclination angle of the bottom of the strip groove is 3-6 degrees.

[0008] In the aforementioned mahjong machine with a controllable lighting, the side of the strip groove near the center of the mahjong machine body is provided with an inclined surface, the inclined surface is opposite to the back of the mahjong tiles in the strip groove, and a light-absorbing layer made of light-absorbing material is provided on the inclined surface.

[0009] In the aforementioned mahjong machine with a controllable lighting lamp, a composite optical module corresponding to the illumination lamp strip is slidably arranged on all four sides of the mahjong machine body. The composite optical module is provided with a polarization filter area and a color vision auxiliary filter area. The polarization filter area is used to convert the light transmitted through it into linearly polarized light, and the color vision auxiliary filter area is used to enhance the contrast between the red light band and the green light band in the light beam. The emitted light from the illumination lamp strip can pass through the polarization filter area or the color vision auxiliary filter area.

[0010] In the aforementioned mahjong machine with controllable lighting, drive components are provided on all four sides of the mahjong machine body, and the drive components are located inside the mahjong machine body. The drive components are used to drive the composite optical module to slide, thereby causing either the polarization filter area or the color vision auxiliary filter area to enter or exit the output light path of the illumination light strip.

[0011] In the aforementioned mahjong machine with a controllable lighting, when the color vision auxiliary filter area enters the outgoing light path of the illumination strip, the polarization filter area simultaneously enters the reflected light observation path of the player's mahjong hand, thereby polarizing and filtering the light reflected from the mahjong hand to the player's eyes.

[0012] In the aforementioned mahjong machine with controllable lighting, the drive assembly includes a motor, a lead screw, a nut, a slide rail, and a slider. The output end of the motor is connected to the lead screw, the nut is fitted on the outside of the lead screw and the two are threaded together, the slider is slidably disposed on the slide rail, and both the nut and the slider are connected to the composite optical module.

[0013] In the aforementioned mahjong machine with controlled lighting, ambient light sensors are installed on all four sides of the main body of the mahjong machine. The ambient light sensors are used to measure the ambient illuminance of the current environment in real time. A dimming drive unit is installed on the illumination strip. The controller has a preset illuminance threshold. When the human body sensing module senses a human body, the ambient light sensor detects the current ambient illuminance and transmits it to the controller. The controller compares it with the preset illuminance threshold range and generates a control signal to drive the dimming drive unit. The dimming drive unit adjusts the brightness of the illumination strip, thereby making the brightness of the illumination strip higher than the ambient illuminance.

[0014] In the aforementioned mahjong machine with controllable lighting, control buttons are provided on all four sides of the main body of the mahjong machine. The control buttons are used to control the drive component through the controller, thereby switching either the polarization filter area or the color vision auxiliary filter area to enter or exit the output light path of the illumination light strip.

[0015] In summary, the advantages of this invention compared to the prior art are as follows:

[0016] 1. By covering the area where the mahjong tiles are placed with the beam of light from the light strip, an effective light zone is formed on the mahjong tiles, which enhances the user's ability to identify the mahjong tiles, improves the user experience, and avoids problems such as blurred vision and difficulty in distinguishing tile details when users identify mahjong tiles due to limited ambient light.

[0017] 2. The intelligent automatic start and stop of the illumination strips is achieved through the human body sensing module and controller. The corresponding illumination strips are turned on only in the direction of people, while the illumination strips in the unoccupied areas remain off. This significantly reduces the energy consumption caused by ineffective lighting. While ensuring ease of use, it greatly improves the energy-saving effect. Users do not need to manually operate the lights to switch them on and off.

[0018] 3. The beam of light from the illumination strip is confined within the slot, ensuring that only the player directly facing the slot receives sufficient reflected light from the card. Furthermore, the brightness of the light beam is higher than that of the ambient light, creating a localized high-illuminance area within the slot. This effectively suppresses external light interference, thereby enhancing the visibility and clarity of the player's hand from their own perspective. It also reduces the possibility of light spreading in other directions and decreases the visibility from other angles, significantly reducing the risk of accidental leakage of hand information.

[0019] 4. The mahjong light strip uses an upward-sloping beam of light to illuminate the tiles. The reflected light intersects with the player's natural downward line of sight, which not only significantly improves the efficiency of light energy utilization, but also enhances the brightness, contrast and pattern recognition of the tiles. The mahjong tiles are placed at a slight upward angle in the strip slot, which naturally matches the player's slightly forward-leaning line of sight when seated. This allows the player to obtain a complete and clear view of the tiles without adjusting their head, reducing neck fatigue and improving recognition speed and comfort.

[0020] 5. By inserting the polarization filter area into the output light path of the illumination strip, the light beam of the illumination strip shines onto the surface of the mahjong tiles through the polarization filter area, which can effectively suppress diffuse reflection and specular reflection on the surface of the tiles, thereby reducing glaring light spots. This makes the colors of the patterns and characters on the surface of the mahjong tiles more realistic, the details clearer, and the overall presentation of higher contrast and transparency.

[0021] 6. The color vision assist filter area is cut into the output light path of the illumination strip. The light beam of the illumination strip shines on the surface of the mahjong tiles through the color vision assist filter area. The color vision assist filter area enhances the contrast between the red and green light bands, thereby helping players with color vision disorders to more easily and accurately distinguish key color elements such as "Red Dragon" and "Green Dragon" in the mahjong tiles, thus improving the fairness and inclusivity of the entertainment.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] A mahjong machine with controllable lighting, such as Figures 1 to 8 As shown, the mahjong machine includes a main body 1, and each of the four sides of the main body 1 is provided with a light strip 2 for rotating. Each of the four sides of the main body 1 is provided with a placement area for placing mahjong tiles. The beam of light from the light strip 2 is tilted upwards and directed at the mahjong tiles in the corresponding placement area.

[0033] By projecting the light beam from the light strip 2 upwards at an angle onto the mahjong tiles within the designated area, a uniform and focused illumination zone is formed on the tiles. This enhances the user's ability to identify the tiles, improving the user experience. Simultaneously, it effectively avoids visual blurring and difficulty in distinguishing tile details caused by limited ambient light, ensuring that users can clearly identify tile information under various lighting conditions.

[0034] Furthermore, a controller 3 is installed on the main body 1 of the mahjong machine, and human body sensing modules 4 are installed on all four sides of the main body 1. Several human body sensing modules 4 are electrically connected to the controller 3. The controller 3 is electrically connected to several illumination lamp strips 2. When the human body sensing module 4 senses a human body, the controller 3 controls the corresponding illumination lamp strip 2 to turn on. In addition, there are adjustment knobs 5 on all four sides of the main body 1 for adjusting the brightness of the corresponding illumination lamp strip 2. The adjustment knobs 5 are connected to the corresponding illumination lamp strip 2, that is, the user can adjust the brightness of the illumination lamp strip 2 by manually rotating the adjustment knobs 5.

[0035] The controller 3, in conjunction with the human body sensing module 4, enables intelligent automatic start and stop of the illumination strips 2. The controller 3 only drives the corresponding illumination strip 2 to turn on when the human body sensing module 4 detects a human body at the corresponding location. The illumination strips 2 in unoccupied areas remain off, significantly reducing ineffective lighting energy consumption. This balances energy saving and ease of use, and eliminates the need for manual switching by the user. Each illumination strip 2 is independently controlled, avoiding light redundancy and visual interference caused by all illumination strips 2 being constantly lit simultaneously when a user is using the device on one side. This improves the rationality of scene adaptation. The adjustment knob 5 allows users to adjust the brightness according to their own visual habits and the ambient light intensity, thus adapting to the needs of people with different visual abilities and further enhancing scene adaptability and the integrity of the user experience.

[0036] In this embodiment, the main body 1 of the mahjong machine is provided with strip grooves 6 on all four sides for vertically placing mahjong tiles. The strip grooves 6 are placement areas, and the beam of light from the illuminating light strip 2 covers and is completely located within the strip grooves 6.

[0037] Several illumination strips 2 are located on the side of the corresponding strip groove 6 away from the center of the mahjong machine body 1. It should be noted that the beam of the illumination strip 2 is obliquely directed from bottom to top toward the vertically placed mahjong tiles. The beam of the illumination strip 2 is confined within the strip groove 6, so that only the player directly facing the strip groove 6 can receive sufficient light reflected from the mahjong tiles, allowing the user to clearly identify the tile information. For the players opposite and to the side, their line of sight is at a significant angle to the direction of the beam, and because the groove wall of the strip groove 6 effectively blocks the direct scattering path of the light, it is difficult for them to obtain an effective image of their hand through the reflected light from the tile surface, thus physically cutting off the main way of visual peeping. Secondly, the brightness of the beam of the illumination strip 2 is higher than the intensity of the ambient light, which can form a local high-illuminance area within the strip groove 6, further reducing the interference of external light on the tile surface, ensuring that the hand is conspicuous and clear from the player's perspective, while reducing the visibility from other perspectives, and greatly reducing the risk of accidental leakage of hand information.

[0038] It should be noted that since the illumination strip 2 is rotatably mounted on the main body 1 of the mahjong machine, players can manually adjust the angle of the illumination strip according to their own needs.

[0039] The bottom of the strip groove 6 is inclined from low to high from the side closest to the center of the mahjong machine body 1 to the side furthest from the center of the mahjong machine body 1. The inclination angle of the bottom of the strip groove 6 is 3-6 degrees. In this embodiment, the inclination angle of the bottom of the strip groove 6 is preferably 6 degrees. Through the inclined structure of the bottom of the strip groove 6, the mahjong tiles placed at the bottom of the strip groove 6 face the player at a stable elevation angle of 6 degrees. At this angle, the beam of light from the illuminating light strip 2 is directed from bottom to top onto the surface of the mahjong tiles. The reflected light formed naturally intersects with the player's natural line of sight, thereby significantly improving the utilization efficiency of effective light energy. As a result, the brightness and visual contrast of the mahjong tiles observed by the player are enhanced, and the recognition of the patterns and characters on the tiles is better.

[0040] Furthermore, when players sit down, they usually maintain a slightly forward-leaning posture with their eyes naturally looking down. The slight upward angle of the tiles just intersects with this natural line of sight, allowing players to obtain a complete and unobstructed view of their mahjong hand without having to deliberately adjust their head angle. This reduces the fatigue caused by a fixed neck posture for a long time and also improves the speed and comfort of viewing and recognizing the tiles.

[0041] An inclined surface 7 is provided on the side of the strip groove 6 near the center of the mahjong machine body 1. The inclined surface 7 is opposite to the back of the mahjong tiles in the strip groove 6. A light-absorbing layer 9 made of light-absorbing material is provided on the inclined surface 7.

[0042] Preferably, in this embodiment, the light-absorbing layer 9 is preferably made of black matte flocked material. When the light beam from the illuminating light strip 2 shines on the surface of the mahjong tiles, some light will inevitably be diffusely reflected or indirectly irradiated onto the inclined surface 7 behind the mahjong tiles. The light-absorbing layer 9 can efficiently absorb this diffuse light, thereby creating a very high brightness contrast between the mahjong tiles and the background. The surface of the mahjong tiles floats on the black background, further enhancing visual clarity. The light-absorbing layer 9 also eliminates the possibility of light being reflected or scattered secondaryly by the inclined surface 7 to the direction of adjacent players, thereby further reducing the risk of accidental leakage of hand information.

[0043] In this embodiment, the mahjong tiles are placed vertically in the strip groove 6. The depth of the strip groove 6 needs to ensure that the player's fingers do not need to reach too far down when picking up the tiles, thus ensuring smooth and natural operation. The width of the strip groove 6 is sufficient to accommodate 3-4 mahjong tiles side by side, leaving appropriate space for arranging the tiles. The length of the strip groove 6 needs to ensure that the corresponding number of mahjong tiles can be placed normally, leaving appropriate space for arranging the tiles.

[0044] The main body 1 of the mahjong machine is slidably equipped with composite optical modules 10 corresponding to the illumination strips 2 on all four sides. Several composite optical modules 10 extend into the corresponding strip grooves 6 and are located between the illumination strips 2 and the inclined surface 7. The composite optical modules 10 are provided with polarization filter area 11 and color vision auxiliary filter area 12. The polarization filter area 11 is used to convert the light transmitted through it into linearly polarized light, and the color vision auxiliary filter area 12 is used to enhance the contrast between the red light band and the green light band in the light beam. The light emitted from the illumination strips 2 can pass through the polarization filter area 11 or the color vision auxiliary filter area 12.

[0045] A drive assembly 13 is provided on all four sides of the mahjong machine body 1. The drive assembly 13 is located inside the mahjong machine body 1. The drive assembly 13 is used to drive the composite optical module 10 to slide, thereby causing either the polarization filter area 11 or the color vision auxiliary filter area 12 to enter or exit the output light path of the illumination lamp strip 2.

[0046] It should be noted that by driving the composite optical module 10 to slide through the driving component 13, the polarization filter area 11 is cut into the output light path of the illumination light strip 2. The linearly polarized light emitted through the polarization filter area 11 can effectively suppress the diffuse reflection and specular reflection light generated by the smooth surface of the mahjong tiles, thereby reducing the glaring light spots on the mahjong tile surface. This makes the original colors and details of the tile patterns and characters present extremely high contrast and transparency, reducing the impact on the player's clear vision, greatly relieving visual fatigue, improving the player's visual comfort and recognition efficiency, and facilitating long-term gameplay.

[0047] By incorporating the color vision assist filter area 12 into the output light path of the illumination light strip 2, the contrast between the red and green light bands is enhanced through the color vision assist filter area 12. This helps players with color vision deficiencies to more easily and accurately distinguish key color elements such as "Red Dragon" and "Green Dragon" in mahjong tiles. For players with color vision deficiencies such as red-green color blindness or color weakness, this ensures that users can participate in mahjong equally regardless of their color perception ability, thereby improving the fairness and inclusivity of the entertainment.

[0048] In this embodiment, the polarization filter region 11 is preferably a wire grid polarizer, and the color vision auxiliary filter region 12 is preferably a composite filter coating.

[0049] like Figures 6 to 7 As shown, it should be noted that when the color vision assist filter area 12 enters the output light path of the illumination light strip 2, the polarization filter area 11 simultaneously enters the observation light path of the player's mahjong hand. This polarization filter then optimizes the light beam emitted from the mahjong hand to the player's eyes, thereby enhancing the red-green contrast and making the reflected colors of the tiles easier for players with color vision deficiencies to distinguish. The reflected light then enters the human eye after being polarized and filtered by the polarization filter area 11. This ensures fairness and inclusivity in entertainment while also improving visual comfort and recognition efficiency.

[0050] By incorporating the color-assisted filter area 12 into the output light path of the illumination strip 2, the contrast between the red and green light bands is enhanced.

[0051] like Figure 8 As shown, in this embodiment, the drive assembly 13 includes a motor 131, a lead screw 132, a nut 133, a slide rail 134, and a slider 135. The motor 131 is installed inside the mahjong machine body 1 and is electrically connected to the controller 3. The output end of the motor 131 is connected to the lead screw 132, which is rotatably mounted inside the mahjong machine body 1. The nut 133 is fitted onto the outside of the lead screw 132, and the two are threaded together. The slide rail 134 is located inside the mahjong machine body 1, and the slider 135 is slidably mounted on the slide rail 134. The nut 133 and slider 135 are connected to the composite optical module 10 through the connecting block 15. The motor 131 drives the lead screw 132 to rotate, thereby causing the nut 133 to move along the length direction of the lead screw 132. The nut 133 drives the connecting block 15 and slider 135 to slide along the length direction of the slide rail 134. The connecting block 15 drives the composite optical module 10 to move, thereby enabling either the polarization filter area 11 or the color vision auxiliary filter area 12 to enter or exit the output light path of the illumination lamp strip 2.

[0052] Furthermore, ambient light sensors 14 are installed on all four sides of the mahjong machine body 1. The ambient light sensors 14 are used to measure the ambient light intensity of the current environment in real time. A dimming drive unit is installed on the illumination strip 2. The controller 3 has a preset light intensity threshold. When the human body sensing module 4 senses a human body, the ambient light sensor 14 detects the current ambient light intensity and transmits it to the controller 3. The controller 3 compares it with the preset light intensity threshold range and then generates a control signal to drive the dimming drive unit. The dimming drive unit adjusts the brightness of the illumination strip 2 so that the brightness of the illumination strip 2 is higher than the ambient light intensity.

[0053] It should be noted that the priority of adjusting the brightness of the illumination strip 2 by adjusting knob 5 is higher than the priority of adjusting the brightness of the illumination strip 2 by controlling the dimming drive unit through controller 3. That is, when the user adjusts the brightness of the illumination strip 2 by adjusting knob 5, controller 3 will ignore the data of ambient light sensor 14, and the control of the brightness of the illumination strip 2 belongs to adjusting knob 5 until the illumination strip 2 is turned off and then turned on again.

[0054] The preset illuminance threshold includes a first preset value and a second preset value. The first preset value is the minimum guaranteed brightness threshold, which is used to provide basic lighting in dark environments. The second preset value is a specific multiple of the ambient illuminance, which is greater than 1, to ensure that the brightness of the illuminator strip 2 is higher than the ambient illuminance.

[0055] It should be noted that by continuously comparing the ambient light intensity with the preset light intensity threshold, the brightness of the illumination strip 2 is always higher than the ambient light intensity, while remaining stable within a visually comfortable range suitable for card recognition.

[0056] The main body 1 of the mahjong machine is equipped with control buttons 16 on all four sides. The control buttons 16 are used to control the drive component 13 through the controller 3, thereby switching either the polarization filter area 11 or the color vision auxiliary filter area 12 to enter or exit the output light path of the illumination lamp strip 2. That is, the user can select to switch between the polarization filter area 11 or the color vision auxiliary filter area 12 to enter the output light path of the illumination lamp strip 2 by pressing the control button 16.

[0057] The specific embodiments described herein are merely illustrative of the spirit of the invention; those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, but without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
