[0037] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0038] See also Figures 1 to 3 , Figure 1 is a schematic diagram of a luminous keyboard according to an embodiment of the present invention, Figure 2 for Figure 1 A partial exploded diagram of the luminous keyboard in the video. Figure 3 for Figure 1 A partial cross-sectional schematic diagram of the luminous keyboard 1 in FIG.

[0039] like Figures 1 to 3 As shown, the luminous keyboard 1 includes a base plate 10, a frame 12, a plurality of keys 14, a light guide plate 16, a shielding sheet 18, a light source 20, a circuit board 22 and a reflective sheet 24. The frame 12, the keys 14 and the circuit board 22 are located above the base plate 10, and the light guide plate 16, the shielding sheet 18, the light source 20 and the reflective sheet 24 are located below the base plate 10. The circuit board 22 is located between the base plate 10 and the frame 12, the shielding sheet 18 is located between the base plate 10 and the light guide plate 16, the light source 20 is located on one side of the light guide plate 16, and the reflective sheet 24 is located below the light guide plate 16. The light source 20 can be a white light emitting diode or a combination of red, green and blue light emitting diodes, depending on the actual application.

[0040] The frame 12 has a plurality of light-transmitting ribs 120, and the plurality of light-transmitting ribs 120 are located between adjacent keys 14. The plurality of light-transmitting ribs 120 define a plurality of frame holes 122. The plurality of keys 14 are correspondingly located in the plurality of frame holes 122. The keys 14 are exposed from the frame holes 122 and can move up and down in the frame holes 122. The plurality of keys 14 can respectively have a keycap 140, a supporting device 142, and a reset member 144. The keycap 140 is disposed relative to the base plate 10. The keycap 140 can have a light-transmitting area 1400, wherein the light-transmitting area 1400 is surrounded by an opaque area. The supporting device 142 is disposed between the keycap 140 and the base plate 10. When the keycap 140 is pressed, the keycap 140 will move vertically toward the base plate 10 along with the supporting device 142. The reset member 144 is disposed between the key cap 140 and the bottom plate 10 , wherein the reset member 144 may be a rubber dome, but is not limited thereto. The circuit board 22 has a switch corresponding to the key 14 , such as a membrane switch or other trigger switch.

[0041] The bottom plate 10 has a plurality of plate slots 100 and a plurality of plate holes 102, wherein the positions of the plate slots 100 correspond to the positions of the light-transmitting ribs 120 of the frame 12, and the positions of the plate holes 102 correspond to the positions of the light-transmitting areas 1400 of the keycaps 140. Since the light-transmitting ribs 120 of the frame 12 surround the keys 14, the plurality of plate slots 100 also correspondingly surround the plurality of plate holes 102. It should be noted that the number and positions of the plate slots 100 and the plate holes 102 can be determined according to actual applications and are not limited to the embodiments shown in the drawings.

[0042] The light guide plate 16 has a first microstructure area 160 and a second microstructure area 162, wherein the pattern of the first microstructure area 160 may correspond to the shape of the plurality of plate grooves 100 of the bottom plate 10, and the pattern of the second microstructure area 162 may correspond to the shape of the plurality of plate holes 102 of the bottom plate 10, such as Figure 2 In addition, the position of the first microstructure area 160 corresponds to the position of the light-transmitting rib 120 of the frame 12, so as to guide the light transmitted in the light guide plate 16 to be emitted upward. Similarly, the position of the second microstructure area 162 corresponds to the position of the light-transmitting area 1400 of the keycap 140, so as to guide the light transmitted in the light guide plate 16 to be emitted upward.

[0043] The plurality of light-transmitting ribs 120, the plurality of plate grooves 100 and the first microstructure area 160 are arranged in an overlapping manner, so that the light emitted by the light source 20 can be projected from the light-transmitting ribs 120 of the frame 12 through the light guide plate 16, the shielding sheet 18 and the plate grooves 100. By overlapping the light-transmitting ribs 120, the plate grooves 100 and the first microstructure area 160, the amount of light projected from the light-transmitting ribs 120 of the frame 12 can be effectively increased, and the consistency of the overall light emission can be improved.

[0044] In addition, the light-transmitting area 1400, the plurality of plate holes 102, and the second microstructure area 162 are arranged to overlap with each other, so that the light emitted by the light source 20 can be projected from the light-transmitting area 1400 of the keycap 140 through the light guide plate 16, the shielding sheet 18, and the plate holes 102. By overlapping the light-transmitting area 1400, the plate holes 102, and the second microstructure area 162, the amount of light projected from the light-transmitting area 1400 of the keycap 140 can be effectively increased, and the consistency of the overall light emission can be improved.

[0045] In this embodiment, the reflective sheet 24 can be used to recycle light or assist light emission. Specifically, the reflective sheet 24 can help guide the light escaping from the light guide plate 16 into the light guide plate 16 for recycling, which helps the subsequent light emission effect of the outer or even adjacent key 14.

[0046] The shielding sheet 18 includes a shielding layer 180, a reflective layer 182 and a protective layer 184, wherein the shielding layer 180, the reflective layer 182 and the protective layer 184 can be stacked on each other in various ways. For example, any one of the shielding layer 180, the reflective layer 182 and the protective layer 184 can be stacked on the top, the middle or the bottom to form the shielding sheet 18. The shielding layer 180 is made of an opaque material. The reflective layer 182 can have both reflective and translucent properties, that is, the reflective layer 182 can reflect part of the light and allow part of the light to pass through. The shielding layer 180 can be a black material, and the reflective layer 182 can be a white material, but it is not limited thereto. In the present embodiment, the shielding layer 180 is overlapped with the gap G between the keycap 140 and the light-transmitting rib 120, such as Figure 3 The shielding layer 180 can block light to prevent light from leaking from the gap G between the key cap 140 and the light-transmitting rib 120. In this way, the overall light output can be more uniform.

[0047] See also Figure 4 , Figure 4 FIG. 4 is a partial schematic diagram of a luminous keyboard 1 according to another embodiment of the present invention.

[0048] like Figure 4 As shown, the light guide plate 16 may have a light color conversion layer 164, wherein the light color conversion layer 164 is overlapped with the light-transmitting rib 120. Therefore, the first color light (e.g., white light) emitted by the light source 20 may be guided to the light color conversion layer 164 via the light guide plate 16, and then the first color light is converted into a second color light (e.g., red light) via the light color conversion layer 164 and emitted from the light-transmitting rib 120. The first color light is different from the second color light. In this way, the key 14 and the frame 12 may emit different color lights, thereby providing the user with a richer visual effect. In practical applications, a color coating may be printed or sprayed on the top surface of the light guide plate 16 to form the light color conversion layer 164.

[0049] See also Figure 5 , Figure 5 FIG. 2 is a partial schematic diagram of an illuminated keyboard according to another embodiment of the present invention. Figure 5 As shown, the circuit board 22 may have a light color conversion layer 220, wherein the light color conversion layer 220 is overlapped with the light-transmitting rib 120. Therefore, the first color light (e.g., white light) emitted by the light source 20 may be guided to the light color conversion layer 220 via the light guide plate 16, and then the first color light is converted into a second color light (e.g., red light) via the light color conversion layer 220 and emitted from the light-transmitting rib 120. The first color light is different from the second color light. In this way, the button 14 and the frame 12 can emit different colors of light, thereby providing the user with a richer visual effect. In practical applications, a color coating may be printed or sprayed on the top or bottom surface of the circuit board 22 to form the light color conversion layer 220.

[0050] See also Figure 6 , Figure 6 FIG. 2 is a partial schematic diagram of light-transmitting ribs according to some other embodiments of the present invention. Figure 6 In each of the illustrated embodiments, at least one side of the light-transmitting rib 120 may have a light color conversion layer 124. Therefore, the first color light (e.g., white light) emitted by the light source 20 may be guided to the light-transmitting rib 120 via the light guide plate 16, and then the first color light is converted into a second color light (e.g., red light) via the light color conversion layer 124 and emitted from the light-transmitting rib 120. The first color light is different from the second color light. In this way, the key 14 and the frame 12 may emit different colors of light, thereby providing the user with a richer visual effect. In practical applications, the frame 12 may be injection molded with materials of different colors, and the light color conversion layer 124 may be formed on the light-transmitting rib 120, or the light color conversion layer 124 may be formed by spraying paint on the light-transmitting rib 120.

[0051] See also Figure 7 , Figure 7 FIG. 1 is a partial schematic diagram of an luminous keyboard according to some other embodiments of the present invention. Figure 7 In each of the illustrated embodiments, the light-transmitting rib 120 may have a protrusion 126, and the protrusion 126 extends toward the light guide plate 16. In one embodiment, the protrusion 126 may not pass through the circuit board 22 and the bottom plate 10. In another embodiment, the protrusion 126 may pass through the circuit board 22 but not through the bottom plate 10. In another embodiment, the protrusion 126 may pass through the circuit board 22 and the bottom plate 10. The light emitted by the light source 20 may be guided to the protrusion 126 via the light guide plate 16, and then emitted from the light-transmitting rib 120. Since the protrusion 126 is closer to the light guide plate 16, the amount of light projected from the light-transmitting rib 120 may be effectively increased.

[0052] See also Figure 8 and Fig. 9 , Figure 8 is a partial exploded schematic diagram of a luminous keyboard according to another embodiment of the present invention, Fig. 9 for Figure 8 The main difference between the luminous keyboard 1' and the above-mentioned luminous keyboard 1 is that the luminous keyboard 1' comprises a first light guide plate 16a, a second light guide plate 16b, a first shielding sheet 18a, a second shielding sheet 18b, a first light source 20a and a second light source 20b.

The first light source 20a and the second light source 20b can be white light emitting diodes or a combination of red, green and blue light emitting diodes, depending on the actual application. In addition, the first light source 20a and the second light source 20b can be located on the same light bar or on different light bars, depending on the actual application. It should be noted that, Figures 8 to 9 Zhongyu Figures 2 to 3 The elements with the same reference numerals shown in the figure have substantially the same working principles and structural configurations, which will not be described in detail here.

[0053] The first light guide plate 16a has a first microstructure area 160, and the second light guide plate 16b has a second microstructure area 162, wherein the pattern of the first microstructure area 160 may correspond to the shape of the plurality of plate grooves 100 of the bottom plate 10, and the pattern of the second microstructure area 162 may correspond to the shape of the plurality of plate holes 102 of the bottom plate 10, such as Figure 8 In addition, the position of the first microstructure area 160 corresponds to the position of the light-transmitting rib 120 of the frame 12, so as to guide the light transmitted in the light guide plate 16 to be emitted upward. Similarly, the position of the second microstructure area 162 corresponds to the position of the light-transmitting area 1400 of the keycap 140, so as to guide the light transmitted in the light guide plate 16 to be emitted upward.

[0054] The plurality of light-transmitting ribs 120, the plurality of plate grooves 100 and the first microstructure area 160 are arranged in an overlapping manner, so that the light emitted by the first light source 20a can be projected from the light-transmitting ribs 120 of the frame 12 through the first light guide plate 16a, the first shielding sheet 18a and the plate grooves 100. By overlapping the light-transmitting ribs 120, the plate grooves 100 and the first microstructure area 160, the amount of light projected from the light-transmitting ribs 120 of the frame 12 can be effectively increased, and the consistency of the overall light emission can be improved.

[0055] In addition, the light-transmitting area 1400, the plurality of plate holes 102, and the second microstructure area 162 are arranged to overlap with each other, so that the light emitted by the second light source 20b can be projected from the light-transmitting area 1400 of the keycap 140 through the second light guide plate 16b, the second shielding sheet 18b, the first light guide plate 16a, the first shielding sheet 18a, and the plate holes 102. By overlapping the light-transmitting area 1400, the plate holes 102, and the second microstructure area 162, the amount of light projected from the light-transmitting area 1400 of the keycap 140 can be effectively increased, and the consistency of the overall light emission can be improved.

[0056] In this embodiment, the first light source 20a can emit a first color light (e.g., white light), and the second light source 20b can emit a second color light (e.g., red light). The first color light is different from the second color light. In this way, the button 14 and the frame 12 can emit different colors of light, thereby providing the user with a richer visual effect.

[0057] The first shielding sheet 18a may include a first shielding layer 180a. Figure 8 As shown, the first shielding layer 180a overlaps with the first microstructure area 160 of the first light guide plate 16a, and the first shielding layer 180a does not overlap with the second microstructure area 162 of the second light guide plate 16b. The first shielding layer 180a can help guide the light escaping from the first light guide plate 16a and / or the second light guide plate 16b into the first light guide plate 16a and / or the second light guide plate 16b for recycling, which helps the subsequent light emission effect of the outer side or even another adjacent key 14.

[0058] The second shielding sheet 18b may include a second shielding layer 180b. The second shielding layer 180b is opaque. The second shielding layer 180b may be black paint, but is not limited thereto. In this embodiment, the second shielding layer 180b is overlapped with the gap G between the key cap 140 and the light-transmitting rib 120, such as Fig. 9 The second shielding layer 180b can block the light to prevent the light from leaking from the gap G between the key cap 140 and the light-transmitting rib 120. In this way, the overall light output can be more uniform.

[0059] See also Fig.10 , Fig.10 FIG. 1 is a partial exploded schematic diagram of a luminous keyboard 1 ″ according to another embodiment of the present invention.

[0060] The main difference between the luminous keyboard 1' and the above-mentioned luminous keyboard 1' is that the plurality of light-transmitting ribs 120, the plurality of plate grooves 100 and the second microstructure area 162 of the luminous keyboard 1' are arranged overlappingly, and the light-transmitting area 1400, the plurality of plate holes 102 and the first microstructure area 160 of the luminous keyboard 1' are arranged overlappingly, such as Fig.10 It should be noted that the working principle of the luminous keyboard 1 ″ is substantially the same as that of the luminous keyboard 1 ′ described above, and will not be described in detail here.

[0061] In one embodiment, the bottom plate 10 may be a transparent bottom plate, but is not limited thereto.

[0062] See also Fig.11 , Fig.11 Schematic diagram of some parts of light-transmitting ribs according to other embodiments of the present invention. Fig.11 In each of the embodiments shown, the light-transmitting ribs 120 are Figures 8 to 10The keycap 140 shown may have a light shielding layer 128 on the opposite side. The light shielding layer 128 can absorb the light leaking from the side of the keycap 140 to prevent the light-transmitting rib 120 from producing a color mixing effect. In addition, in some embodiments, the bottom of the light-transmitting rib 120 may have a groove 130. The groove 130 can further reduce the light leaking from the side of the keycap 140 from entering the bottom of the light-transmitting rib 120. In practical applications, the frame 12 can be injection-molded with materials of different colors, and the light shielding layer 128 can be formed on the light-transmitting rib 120, or the light-transmitting rib 120 can be sprayed with paint to form the light shielding layer 128.

[0063] In summary, the frame of the luminous keyboard of the present invention has light-transmitting ribs. The light emitted by the light source can be guided by the light guide plate to the light-transmitting ribs. In this way, the frame of the luminous keyboard can emit light, thereby bringing users richer visual effects.

[0064] Of course, the present invention may have many other embodiments.
