Description

Technical Field

[0001] The utility model belongs to the technical field of musical instruments, and in particular relates to a light-emitting component with a light-channeling prevention function. Background Art

[0002] In the field of electronic keyboards and electric pianos, some luminous characters need to be displayed on the cover for indication. Generally speaking, the current practice is to spray black on the surface of the silicone button first, then hollow out the desired characters by laser engraving, and light up the LED light under the silicone, and the hollowed-out characters on the silicone surface will glow and appear. In order to make the characters look bright and conspicuous, high-brightness LED lights are usually used. This brings another problem: there will be light leakage between adjacent silicone buttons, especially the red and green LED lights will have more obvious light leakage.

[0003] Existing methods for preventing light leakage of silicone buttons on the keyboard cover include:

[0004] (1) Use a black pen to paint the inside of the silicone button black: This method requires using a black pen to paint the inside of the silicone button black. If the button structure is small, the black pen cannot reach into the button to operate. Therefore, this method is not only difficult to operate, but also not suitable for silicone button structures with small sizes, and production quality is difficult to control;

[0005] (2) Paste black velvet paper inside the silicone button: This method cannot be used if the button structure is too small, and the adhesion between the silicone surface and the black velvet paper is not good. The black velvet paper often falls off due to the loose adhesion, making it difficult to control production quality;

[0006] (3) Pasting a black silicone light-shielding cover inside the button: This method requires a mold for the light-shielding cover to be made separately according to the internal size and structure of the silicone button to produce the silicone light-shielding cover. This method requires a special light-shielding mold, which has a high production cost. Moreover, this light-shielding cover is a mold specially made according to the internal structure of the button, so this light-shielding cover is also a special part and cannot be used with other silicone buttons. It has poor versatility and high cost. In addition, the light-shielding cover needs to be glued to the inside of the silicone button. Due to the small internal structure space of the silicone button, it is difficult to apply glue, and the amount of glue used is also difficult to accurately control. Glue often overflows or remains, thus affecting the light transmittance of the silicone button. Utility Model Content

[0013] In some embodiments, the clip is provided with two clamping grooves with an angle of 90°.

[0014] In some embodiments, a first baffle and a second baffle are constructed on both sides of the clamping groove, the height of the first baffle is higher than the second baffle, and the top end of the first baffle abuts against the inner wall of the silicone button.

[0017] In some embodiments, a face shell is further included, and the face shell is fixed to the circuit board by screws, so that the outer edge of the silicone button is pressed against the circuit board.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] The clamping groove in the clip is clamped on the partition between the two inner cavities. When the light point emits light, it can only emit light in the corresponding inner cavity.

When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices but have an intermediate device.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] Reference Figure 1 to Figure 2 The utility model provides a light-emitting component with anti-light channeling function, comprising:

[0030] A light-emitting substrate 1 is provided with a plurality of light-emitting points 2, which are arranged in an array on the light-emitting substrate 1, and each light-emitting point 2 is spaced a certain distance apart;

[0031] A silicone button 3 is constructed with the same number of inner cavities 4 as the number of light-emitting points 2. The top of each inner cavity 4 is hollowed out with characters by laser engraving. The position of the inner cavity 4 corresponds to the position of the light-emitting point 2. The adjacent inner cavities 4 are isolated from light by partitions 41. The partitions 41 are connected to each other to form a grid of the inner cavities 4.

[0032] The clip 5 is opaque and has at least one clamping groove 6, which is used to be clamped on the partition 41, and uses the structures on both sides of the clamping groove 6 to block the light of the corresponding two side cavities 4, the bottom surface of the clamping groove 6 abuts against the light-emitting substrate 1, and at least a part of the top surface abuts against the inner wall of the silicone button 3.

[0033] It should be noted that the clamping groove 6 can be used to fix the clip 5 and the partition 41, and after the clamping groove 6 is fixed to the partition 41, the strength of the partition 41 is also strengthened. When the top of the silicone button 3 is pressed, the area where the partition 41 is located will not sink due to the action of the clamping groove 6, thereby playing a supporting role. In addition, the structures on both sides of the clamping groove 6 can effectively isolate the light from the inner cavity 4 on both sides to avoid light leakage.

[0034] Preferably, the clip 5 is made of an integrally formed light-proof metal material, such as stainless steel or iron.

[0035] As an implementation manner, the clip 5 is provided with a clamping groove 6 , and each partition 41 is correspondingly clamped with a clip 5 , and the clip 5 of a corresponding length is designed according to the length of the partition 41 .

[0036] Combination Figure 3 As an implementation mode, in order to adapt to the two partitions 41 arranged at an angle of 90°, the clip 5 is provided with two clamping grooves 6 at an angle of 90°. The two partitions 41 are clamped at the same time by one clip 5 to achieve shading of the two partitions 41. Moreover, since the layout of the inner cavity 4 in the silicone button 3 is relatively regular, the inner cavities 4 of the same size are arranged in one row or more, and the structural dimensions of the partitions 41 between the inner cavities 4 are regular, so the versatility is improved by universal design of the clip 5.

[0037] Furthermore, a first baffle 7 and a second baffle 8 are constructed on both sides of the clamping groove 6. The height of the first baffle 7 is higher than that of the second baffle 8, and the top of the first baffle 7 abuts against the inner wall of the silicone button 3; the upper part of the second baffle 8 is close to the direction of the first baffle 7, and the top of the second baffle 8 is provided with an outward-bending guiding slope.

[0038] It should be noted that the heights of the baffles on both sides of the clamping groove 6 are different. The first baffle 7 is higher and perpendicular to the bottom surface of the clamping groove 6. It mainly plays a role of shading and supporting. The first baffle 7 needs to support the height of the entire partition 41 to prevent the partition 41 from deforming; in addition, the second baffle 8 is inclined to the bottom surface of the clamping groove 6 and moves closer to the first baffle 7. Through the change in the distance between the first baffle 7 and the second baffle 8, a clamping elastic preload force is provided to ensure the fixation between the clip 5 and the partition 41, and the guiding slope can guide the clip 5 to be smoothly pushed along the partition 41 from its bottom to the top.

[0039] In the present embodiment, the light-emitting substrate 1 is a circuit board, the light-emitting point 2 is an LED lamp, the LED lamps are distributed in an array on the circuit board, and the LED lamps are a certain distance apart; further, it also includes a surface shell 9, the surface shell 9 and the circuit board are fixed by screws 10, and the outer edge of the silicone button 3 is pressed against the circuit board.

[0040] In summary, compared with the prior art, the above embodiment provides a light-emitting component with an anti-light-channeling function, which is clamped on the partition 41 between the two inner cavities 4 by the clamping groove 6 in the clip 5. When the light point 2 emits light, it can only emit light in the corresponding inner cavity 4. The structures on both sides of the clamping groove 6 are used to block the light of the corresponding inner cavities 4 on both sides to achieve the anti-light-channeling function. It is universally designed according to the structural dimensions of the partition 41 and has strong versatility.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
