Description

Technical Field

[0001] This invention relates to a light-emitting card, and more particularly to a light-emitting card that can present a transparent and three-dimensional light-emitting effect when it emits light. Prior Technology

[0002] Since traditional transaction cards do not have any function of emitting light after a transaction, some companies have developed a transaction card that emits light after a transaction. Summary of the Invention

[0003] However, typical illuminated cards only use a light source in conjunction with a light-transmitting part to emit light, which makes the light source prone to dissipation. This not only results in a weak light source but also leads to an inconspicuous luminous effect due to the planar light emission.

[0004] Therefore, the purpose of this invention is to actively reveal how to invent a light-emitting card that can present a transparent and three-dimensional light-emitting effect when it emits light, thereby effectively improving the shortcomings of conventional cards.

[0005] In view of the shortcomings of the aforementioned conventional technology, the inventor felt that it was not perfect, so he devoted his mind to researching and overcoming them, and then developed a light-emitting card in order to present a transparent and three-dimensional light-emitting effect.

[0006] To achieve the above and other objectives, the present invention provides a light-emitting card, comprising: a refractive plate, a light-emitting unit, an electronically controlled transaction unit, a front panel, and a back panel. The refractive plate includes at least one pattern cutout portion, which has a first refractive surface, a second refractive surface, a third refractive surface, a first included angle, a second included angle, and a light channel. The second refractive surface is inclined to one side of the first refractive surface, and the third refractive surface is inclined to the other side of the first refractive surface. The first included angle is located between one end of the first refractive surface and one end of the second refractive surface, and the second included angle is located between the other end of the first refractive surface and one end of the third refractive surface. The channel is located inside the first refractive surface, the second refractive surface, and the third refractive surface; the light-emitting unit is disposed on the refractive plate and corresponds to one side of the pattern cutout; the electronically controlled transaction unit is disposed on the refractive plate and electrically connected to the light-emitting unit; the panel is stacked on the top surface of the refractive plate, the panel includes a panel light-shielding part and a light-transmitting part, the panel light-shielding part is located around the light-transmitting part, and the light-transmitting part corresponds to the pattern cutout; the back plate is stacked on the bottom surface of the refractive plate, and the back plate is provided with a back plate light-shielding part.

[0007] In one embodiment of the present invention, the refractive plate is made of a light-transmitting material.

[0008] In one embodiment of the present invention, the cross section of the optical channel is made into an inverted trapezoid by means of the first refractive surface, the second refractive surface, the third refractive surface, the first included angle and the second included angle.

[0009] In one embodiment of the present invention, the angle between the first included angle and the second included angle is greater than 90 degrees.

[0010] In one embodiment of the present invention, a support frame is further included, which is disposed between the panel and the back plate and located at the outer edge of the refractive plate.

[0011] In one embodiment of the present invention, the support frame is made of a non-transparent material.

[0012] In one embodiment of the present invention, the light-emitting unit includes at least one lateral light-emitting diode, the lateral light-emitting diode corresponding to the second refractive surface or the third refractive surface of the pattern cut portion.

[0013] In one embodiment of the present invention, the electronically controlled transaction unit includes at least a sensing transmission module and a transaction processing control module, wherein the transaction processing control module is electrically connected to the sensing transmission module and the light-emitting unit.

[0015] In one embodiment of the present invention, the light-shielding portion of the panel and the light-shielding portion of the back panel are made of colored material or printed with patterns.

[0016] Therefore, the light-emitting card of the present invention can guide the light source to the pattern cut section of the refractive plate by the light-emitting unit, and through the cooperation of the first refractive surface, the second refractive surface and the third refractive surface, the light source is refracted multiple times and then guided to the panel through the light channel to present a transparent and three-dimensional light-emitting effect.

[0023] To fully understand the purpose, features, and effects of this invention, the invention will be described in detail below with reference to the specific embodiments and accompanying drawings, as follows:

[0024] Please refer to Figures 1 to 5. As shown in the figures, the present invention provides a light-emitting card 1, which includes at least a refractive plate 11, a light-emitting unit 12, an electronically controlled transaction unit 13, a front panel 14, and a back panel 15.

[0025] The refractive plate 11 includes at least one pattern cut portion 110. The pattern cut portion 110 is provided with a first refractive surface 111, a second refractive surface 112, a third refractive surface 113, a first included angle 114, a second included angle 115, and a light channel 116. The second refractive surface 112 is inclinedly disposed on one side of the first refractive surface 111, and the third refractive surface 113 is inclinedly disposed on the other side of the first refractive surface 111. The first included angle 114 is located between one end of the first refractive surface 111 and one end of the second refractive surface 112. The second included angle 115 is located between the other end of the first refractive surface 111 and one end of the third refractive surface 113. The light channel 116 is located inside the first refractive surface 111, the second refractive surface 112, and the third refractive surface 113 respectively.

[0026] The light-emitting unit 12 is disposed on the refractive plate 11 and corresponds to one side of the pattern cut-out portion 110. For example, it can correspond to the outer side of the second refractive surface 112 or the outer side of the third refractive surface 113 as required. In this invention, the outer side of the second refractive surface 112 is used as an embodiment.

[0027] The electronically controlled transaction unit 13 is disposed on the refractive plate 11 and electrically connected to the light-emitting unit 12. The electronically controlled transaction unit 13 includes at least a sensing transmission module 131 and a transaction processing control module 132. The transaction processing control module 132 is electrically connected to the light-emitting unit 12 and the sensing transmission module 131. The sensing transmission module may be an inductive coil, a contact chip, or a combination thereof. The sensing transmission module 131 senses at least one payment device (e.g., an inductive reader) to obtain power. The transaction processing control module 132 may be a microcontroller, a central processing unit, an integrated circuit chip, or a logic circuit that stores personal identity data, account data, and transaction data.

[0028] The panel 14 is stacked on the top surface of the refractive plate 11. The panel 14 includes a panel light-blocking portion 141 and a light-transmitting portion 142. The panel light-blocking portion 141 is located around the light-transmitting portion 142. The light-transmitting portion 142 corresponds to the pattern cutout portion 110. The panel light-blocking portion 141 may be a colored material or printed with a pattern.

[0029] The back plate 15 is stacked on the bottom surface of the refractive plate 11. The back plate 15 is provided with a back plate light-shielding part 151, wherein the back plate light-shielding part 151 may be a colored material or printed with a pattern.

[0030] When in use, the luminous card 1 can be brought close to the payment device, allowing the sensing transmission module 131 to sense the payment device and obtain power. This power is then supplied to the transaction processing control module 132 and the luminous unit 12. The transaction processing control module 132 performs integrated calculations and generates a transaction signal based on the transaction details. Simultaneously, the transaction processing control module 132 transmits this transaction signal to the luminous unit 12. Upon receiving the transaction signal from the transaction processing control module 132, the luminous unit 12 is driven by the transaction signal to illuminate. The light source is guided to the pattern cut section 110 by the refractive plate 11 itself. When the light source enters through the second refractive surface 112 of the pattern cut section 110, the first refractive surface 111 in a planar state, the second refractive surface 112 in an inclined state, and the third refractive surface 113 in an inclined state cooperate with each other to allow the light source to undergo multiple refractions in the light channel 116 by the first refractive surface 111, the second refractive surface 112, and the third refractive surface 113. After multiple refractions, the light source passes through the light channel 116 and is emitted from the light-transmitting part 142 to present a transparent and three-dimensional light-emitting effect.

[0031] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that the angle between the first included angle 114 and the second included angle 115 is greater than 90 degrees. The cross-section of the light channel 116 is made into an inverted trapezoid by the first refractive surface 111, the second refractive surface 112, the third refractive surface 113, the first included angle 114, and the second included angle 115. Thus, the angle between the first included angle 114 and the second included angle 115 allows the second refractive surface 112 and the third refractive surface 113 to form the desired tilt angle. Through the cooperation of the first refractive surface 111, the second refractive surface 112, and the third refractive surface 113, the light source undergoes multiple refractions in the light channel 116, and the refracted light source passes through the light channel 116 and is emitted from the light-transmitting part 142, presenting a transparent and three-dimensional light-emitting effect.

[0032] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that the thickness variation of the pattern in the pattern cut portion 110 can be controlled by the first included angle 114 and the second included angle 115 at different angles. For example, the larger the angle between the first included angle 114 and the second included angle 115, the thicker the lines of the pattern cut portion 110 can be, and conversely, the smaller the angle, the thinner the lines of the pattern cut portion 110 can be.

[0033] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that the three-dimensional changes of the pattern in the pattern cut-out portion 110 can be controlled by the light channel 116 of different depths. For example, part a of Figure 5 shows a shallower light channel 116 and its corresponding pattern cut-out portion 110 that refracts the light source, while part b of Figure 5 shows a deeper light channel 116 and its corresponding pattern cut-out portion 110 that refracts the light source. The deeper the light channel 116, the more obvious the three-dimensional effect of the pattern cut-out portion 110 can be.

[0034] Furthermore, the refractive plate 11 can be made of light-transmitting materials such as PVC, PET, PC, and transparent plastic sheets, depending on the requirements. The pattern cutout 110 can be processed using chemical etching, CNC machining, cutting, waterjet cutting, or other cutting techniques to form the desired luminescent pattern or text. This allows the invention to better meet the needs of practical applications.

[0035] In addition to the above embodiments, one embodiment of the present invention differs from the above embodiments in that it further includes a support frame 16. The support frame 16 is disposed between the panel 14 and the back plate 15 and is located at the outer edge of the refractive plate 11, that is, at the central layer of the light-emitting card 1. In this way, the support frame 16 can be used as a support for the combination of the refractive plate 11, the light-emitting unit 12, the electronic control transaction unit 13, the panel 14 and the back plate 15, to prevent damage caused by heavy pressure, or warping or deformation, so that the light-emitting card 1 has better structural stability, and allows the refractive plate 11, the light-emitting unit 12 and the electronic control transaction unit 13 to achieve good electrical characteristics and light guiding effect when in operation, so as to maintain stable operation during use.

[0036] In addition to the above embodiments, in one embodiment of the present invention, the difference is that the support frame 16 may be made of a non-transparent material. Thus, the support frame 16 can achieve a good light-shielding effect, effectively preventing scattering of light from the light-emitting unit 12 when the light source is transmitted to the pattern cutout 110 of the refractive plate 11, thereby effectively maintaining the stability of the light source transmission.

[0037] In addition to the embodiments described above, in one embodiment of the present invention, the difference lies in that the light-emitting unit 12 includes at least one lateral light-emitting diode 121, which corresponds to the second refractive surface 112 or the third refractive surface 113 of the pattern cut-out portion 110. Thus, the lateral light-emitting diode 121 allows the light source to be directly transmitted from the refractive plate 11 to the second refractive surface 112 or the third refractive surface 113 of the pattern cut-out portion 110, thereby avoiding light source loss due to an excessively long transmission path and effectively maintaining the stability of light source transmission.

[0038] The present invention has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that these embodiments are merely illustrative of the invention and should not be construed as limiting its scope. It should be noted that all variations and substitutions equivalent to these embodiments should be considered within the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
