Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, specifically to a light-emitting device with uniform light transmission. Background Technology

[0002] With the rapid development of electronic and manufacturing technologies and the improvement of people's living standards, people have higher requirements for the decoration of electronic device casings. Traditional methods of decorating electronic device casings, such as printing patterns, inkjet printing, and stickers, lack novelty and are difficult to attract users.

[0003] To cater to users' urgent demand for fashionable and personalized designs, electronic device casings with optical effects have emerged on the market. A significant feature of these casings is the use of LED (Light Emitting Diode) backlighting technology to display patterns. LEDs, as a new type of light-emitting element, have many advantages such as low energy consumption, long lifespan, and fast response speed, leading to their widespread application in the electronic display field. However, directly applying LEDs to the surface decoration of electronic device casings presents a thorny problem. Because LEDs are essentially point light sources, their light-emitting characteristics result in higher brightness around the LED beads and lower brightness in areas farther away. This causes noticeable unevenness in the patterns displayed through LED backlighting, severely affecting the visual effect, reducing the product's aesthetics and perceived quality, and limiting the further promotion and application of casings with optical effects in the market. Therefore, how to solve the problem of uneven pattern display in LED backlighting has become a key technical challenge that urgently needs to be overcome in the current field of electronic device casing decoration.

[0027] Please see Figure 1 The present invention provides a light-emitting device with uniform light transmission, including a housing 1 with a light-transmitting part and a main control board 2, LED beads 3, a flexible circuit board 5 with a light guide plate 4 and a battery 6 disposed inside the housing 1. The main control board 2 is electrically connected to the LED beads 3, the flexible circuit board 5 and the battery 6 respectively. The light guide plate 4 is disposed on the inner side of the light-transmitting part and the LED beads 3 is disposed on one side of the light guide plate 4. The light emitted by the LED beads 3 can be uniformly emitted from the light-transmitting part of the housing 1 after being guided by the light guide plate 4.

[0028] This invention effectively solves the problem of uneven LED backlight display patterns in the existing electronic device casing 1 by setting a flexible circuit board 5 with a light guide plate 4, placing the light guide plate 4 on the inner side of the light-transmitting part, and placing the LED beads 3 on one side of the light guide plate 4. It achieves uniform light transmission from the LEDs, making the emitted light uniform and visually consistent in brightness around the light source. The light beam is evenly emitted at the light guide position, improving the display effect and aesthetics of the light-emitting device, and better meeting users' high-quality requirements for the decoration of the electronic device casing 1. The flexible circuit board 5 with the light guide plate 4 makes the device structure more flexible, facilitating installation and layout.

[0029] Please see Figure 2 In one embodiment, the housing 1 has a limiting groove 101 on the inner side of the light-transmitting portion to limit the installation position of the light guide plate 4. The limiting groove 101 can precisely limit the installation position of the light guide plate 4, ensuring that the light guide plate 4 is in a suitable position to receive and conduct the light emitted by the LED beads 3, thus ensuring the accuracy and stability of light guiding; it avoids the light guide plate 4 from moving randomly within the housing 1 or from deviating from its installation position, thereby affecting the light transmission and uniform light transmission effect, and helps to further improve the uniformity and reliability of the light transmission of the light-emitting device.

[0030] Please see Figure 1 In one embodiment, an inner tray 7 is provided inside the outer casing 1, and the main control board 2, flexible circuit board 5, and battery 6 are all mounted on the inner tray 7. The inner tray 7 provides a centralized mounting platform for the main control board 2, flexible circuit board 5, and battery 6, making the internal structure of the entire device more regular and orderly, helping to optimize the internal space layout, facilitating the wiring connection and signal transmission between various components, and also facilitating the fixation and protection of various components, reducing the shaking of components within the outer casing 1, ensuring the stability and reliability of the device, and indirectly providing a good internal structural foundation for achieving uniform light transmission.

[0031] In one specific embodiment, the inner tray 7 is fixed to the outer shell 1 by screws. Fixing the inner tray 7 with screws ensures that the inner tray 7 is firmly installed in the outer shell 1, enhances the connection strength between the inner tray 7 and the outer shell 1, prevents the inner tray 7 from loosening or shifting during use, and thus ensures the stability of components such as the main control board 2, flexible circuit board 5, and battery 6 installed on the inner tray 7.

[0032] Please see Figure 4 In one specific embodiment, a first mounting groove 701 is provided on one side of the inner tray 7 for vertically mounting the main control board 2. Vertical mounting fully utilizes the space of the inner tray 7, optimizes the internal spatial layout, and makes the relative positions of the main control board 2 and other components more reasonable, facilitating wiring connections and signal transmission. Simultaneously, the first mounting groove 701 ensures the mounting accuracy of the main control board 2, improves the stability of its operation, and thus better controls the LED beads 3 and other components, contributing to uniform light transmission of the light-emitting device.

[0033] In one specific embodiment, a second mounting groove is formed between the other side of the inner tray 7 and the outer casing 1 for vertically mounting the battery 6. Vertical mounting of the battery 6 fully utilizes the internal space of the outer casing 1, optimizing the internal spatial layout and making the relative position of the battery 6 with other components more reasonable, facilitating wiring connections and signal transmission. Simultaneously, the second mounting groove makes the battery 6 more securely mounted, ensuring a continuous and stable power supply to the entire device. This avoids unstable power supply caused by a loose or improperly installed battery 6, which could affect the luminous effect of the LED beads 3 and the uniform light transmission performance of the entire device.

[0034] Please see Figure 1 , Figure 3In one embodiment, a fixing member 8 is provided in the middle of the flexible circuit board 5, and the flexible circuit board 5 is mounted on the top of the inner support 7 through the fixing member 8, with the light guide plate 4 fixed on the top of the fixing member 8. The fixing member 8 secures the flexible circuit board 5 on the top of the inner support 7, making the installation of the flexible circuit board 5 more stable and accurate. Simultaneously, the fixing of the light guide plate 4 to the top of the fixing member 8 ensures the relative positional relationship between the light guide plate 4, the flexible circuit board 5, and other components. This facilitates the transmission of light from the LED beads 3 through the light guide plate 4 on the flexible circuit board 5 to the light-transmitting part, improving the efficiency and accuracy of light transmission, further achieving uniform light transmission of the light-emitting device, and making the entire device structure more compact and stable.

[0035] Please see Figure 3 , Figure 4 In one specific embodiment, the fixing member 8 has through-holes 801 on both sides, and the inner support 7 has two limiting posts 702 on its top that mate with the limiting holes 801. The mate between the limiting holes 801 and the limiting posts 702 can quickly and accurately fix the position of the fixing member 8, thereby ensuring the installation accuracy of the flexible circuit board 5 and the light guide plate 4.

[0036] Please see Figure 1 , Figure 4 In one embodiment, one end of the flexible circuit board 5 is electrically connected to the main control board 2, and the other end of the flexible circuit board 5 is fixed to one side of the inner tray 7 by the charging bracket 9. This ensures that the flexible circuit board 5 is reliably fixed inside the device, avoiding problems such as loose connections and circuit damage caused by the shaking or displacement of the flexible circuit board 5, and guaranteeing the stability and reliability of the entire circuit system. A charging cavity 703 is provided on the side wall of the inner tray 7. The end of the flexible circuit board 5 near the charging bracket 9 extends into the charging cavity 703 and is provided with charging pins 501. When the outer shell 1 is opened, an external charging device can be inserted into the charging cavity 703 and contact the charging pins 501 to charge the external charging device.
