DETAILED DESCRIPTION OF THE INVENTION



[0035] FIG. 1 depicts a first embodiment of a luminous disk device of the present invention. The luminous disk device comprises a luminous disk 10 which could be a shaped disk and a bracing apparatus 71. Users can design patterns on the surface of the luminous disk 10 at their will, such as the dolphins' pattern in this embodiment, with a disk pattern generation device and then print them on a provided light-transmissive sticker sheet with predetermined shapes on it, as shown in FIG. 2, by using a picture output device, such as a regular printer. The printed pattern is then detached from the sticker sheet and stuck on the luminous side of the luminous disk. By this procedure, a personal and unique portable device is formed. The disk pattern generation device can be a personal computer and a printer, or any pattern output device.

[0036] FIG. 3 is an enlarged partial section view of the luminous disk according to the first embodiment of this invention. It should be noticed that the ratio of the sizes of the components in the drawing are not identical with the ratio of the components of the life-size product. The luminous disk 10 disclosed in this embodiment comprises a disk lamination 11 and a light emitting lamination 13, which are combined together by glue. A hole 12 is formed in the center of the disk 10 to be clamped for playing. The disk lamination 11 comprises a flat substrate 113, and a metallic reflecting layer 111 formed on the top of the substrate 113. The substrate 113 is generally made of a transparent plastic material. A pattern which represents digital data can be formed on the substrate 113 for storing digital data. Under this conformation, the disk lamination 11 serves as a CD-ROM. The light emitting lamination 13 comprises an electroluminescence section and a biasing section. The electroluminescence section comprises a dielectric layer 134 and a fluorescent layer 135, the upper surface and the bottom surface of the electroluminescence section are able to receive an external electrical signal applied via the biasing section. The biasing section comprises a distribution layer 132, a bottom electrode layer 133 located between the bottom surface of the electroluminescence section and the distribution layer 132, and a transparent electrode layer 136 located above the upper surface of the electroluminescence section. The light emitting lamination 13 in FIG. 3 further comprises a bottom protection layer 131 located below the distribution layer 132 and an upper protection layer 137 located above the transparent electrode layer 136. Each of the distribution layer 132 and the transparent electrode layer 136 has an exposed area on its upper surface for forming a first conductive terminal 151 and a second conductive terminal 152.

[0037] The upper and lower protection layers 131 and 137 are used for protecting the light emitting lamination and can be constructed by any proper transparent protective material, such as polymer hardened by ultraviolet. The distribution layer 132 is a metallic layer formed by electroplating or any other proper method. An exposed area on the upper surface of the distribution layer 132 and adjacent to the hole 12 is formed for forming the second conductive terminal 152 as an interface to the external electrical signal. The part of the upper surface of the distribution layer 132 other than the exposed area contacts with the bottom electrode layer 133, a metallic layer formed by printing or sputtering, for transmitting the electrical signal received from the second conductive terminal 152 to the bottom electrode layer 133, and the bottom electrode layer 133 then further transmits the signal to the bottom surface of the electroluminescence section. The transparent electrode layer 136, disposed above the electroluminescence section, is a light-transmissive layer made of indium tin oxide (ITO) or indium zinc oxide (IZO) by printing or sputtering. The transparent electrode layer 136 has an exposed area that stretched vertically to cover the other layers of the light emitting lamination 13 at the side of hole 12 for forming the first conductive terminal 151 as an interface to the external electrical signal. It is preferable to have a vertical insulating layer (not labeled) to isolate the first conductive terminal 151 from the other layers of the light emitting lamination 13.

[0038] By means of the bottom electrode layer 133 and the transparent electrode layer 136, the external electrical signal received by the first and the second conductive terminals 151 and 152 can be applied to the upper and the bottom surfaces of the electroluminescence section.

[0039] The fluorescent layer 135 luminesces when it is biased by an electrical signal It may be made of any proper fluorescence material or electroluminescence material; no matter the material itself is organic or inorganic, by printing or sputtering according to the material used. The dielectric layer 134 of the electroluminescence section serves as an insulation layer in case the electroluminescence section is made of inorganic material.

[0040] According to the aforementioned structure, the electroluminescence section will luminesce when an external electrical signal is applied thereon via the first and the second conductive terminals 151 and 152, the distribution layer 132, the bottom electrode layer 133, and the transparent electrode layer 136. Moreover, the luminous disk 10 itself can store digital data by means of its disk lamination 11 and thus can also be taken as a data storage medium. Furthermore, when the disk lamination 11 of the luminous disk 10 is being played, the light emitting lamination 13 can be biased simultaneously by an external electrical signal and thus emit light.

[0041] FIG. 4 is an enlarged partial section view of the disk according to the second embodiment of this invention. As shown in FIG. 4, the luminous disk 20 comprises a disk lamination 11 and a light emitting lamination 13. The disk lamination 11 comprises a substrate 113, a metallic reflecting layer 111, and a dye layer 114 superposed between the substrate 113 and the metallic reflecting layer 111 for forming a pattern representative of encoded digital data under illumination of a laser beam. In this case, the pattern corresponding to the digital data to be stored will be burned onto the dye layer 114 by a laser beam after the luminous disk 20 is finished. In other words, the disk lamination 11 serves as a CD-R. The light emitting lamination 13 includes an electroluminescence section and a biasing section. The electroluminescence section of the light emitting lamination 13 of the luminous disk 20 is consisted of a fluorescence layer 135 and a dielectric layer 134. The biasing section of the light emitting lamination 13 of the luminous disk 20 comprises a distribution layer 132 and a transparent electrode layer 136 located above the upper surface of the electroluminescence section. The light emitting lamination 13 in FIG. 4 further comprises an upper protection layer 137 located above the transparent electrode layer 136.

[0042] In the structure shown in FIG 4, the metallic reflecting layer 111 of the disk lamination 11 serves not only as a reflecting layer but also as a biasing electrode of the fluorescence layer 135, thus the bottom electrode layer 133 and the bottom protection layer 131 in the structure of FIG. 3 are omitted. Moreover, the transparent electrode layer 136 has an exposed area on its upper surface adjacent to the hole 12 for forming a first conductive terminal 151 as an interface to the external electrical signal, while a second conductive terminal 152 is formed by an exposed part of the distribution layer 132.

[0043] According to the aforementioned structure, when an external electrical signal is applied thereon to the first and the second conductive terminals 151 and 152, it will be delivered through the distribution layer 132, the metallic reflecting layer 111, and the transparent electrode layer 136. Then the transparent electrode layer 136 and the metallic reflecting layer 111 transfer the external electrical signal to the upper surface and the bottom surface of the electroluminescence section, thus it will luminesce.

[0044] FIG. 5 is an enlarged partial section view of the luminous disk according to the third embodiment of this invention. The luminous disk 30 comprises a disk lamination 11 and a light emitting lamination 13. The light emitting lamination 13 further comprises a biasing section and an electroluminescence section However, the distribution layer 132 and the dielectric layer 134 in the structure of the luminous disk 10 are removed. Thus, the light emitting lamination comprises a bottom protection layer 131, a bottom electrode layer 133, a fluorescence layer 135, a transparent electrode layer 136, and a top protection layer 137. This structure is especially for a light emitting lamination whose electroluminescence section is made of organic electroluminescence material.

[0045] The first conductive terminal 151 is formed as a circle surrounding the central hole 32 on the upper surface of the transparent electrode layer 136 without being covered by the top protection layer 137. The second conductive terminal 152 is formed also as a circle surrounding the central hole 32 on the upper surface of the bottom electrode layer 133 without being covered by any other layer.

[0046] According to the structure of the luminous disk 30, when an external electrical signal is applied thereon to the first and the second conductive terminals 151 and 152, it would be delivered by the transparent electrode layer 136 and the bottom electrode layer 133, and then the transparent electrode layer 136 and the bottom electrode layer 133 further transfer the external electrical signal to the upper surface and the bottom surface of the electroluminescence section, thus make it luminesce.

[0047] FIG. 6 is an enlarged partial section view of the luminous disk according to the fourth embodiment of this invention. As shown in FIG. 6, the luminous disk 4 also comprises a disk laminatioin 11 and a light emitting lamination 13. The difference between the structure of the luminous disk 30 and the present structure lies in that the structure of the luminous disk 40 does not contain a bottom protection layer 131, a bottom electrode layer 133, and a top protection layer 137; this structure is the simplest one of the luminous disk in the present invention and is good for the light emitting lamination whose electroluminescence section is made of organic electroluminescence material. As in the structure of the luminous disk 30, a first and a second conductive terminal is formed as a circle surrounding the central hole of the disk. The first conductive terminal 151 is formed on the upper surface of the transparent electrode layer 136, and the second conductive terminal 152 is an exposed area formed directly on the metallic reflecting layer 111 which is taken as a bottom electrode here.

[0048] In this simplest structure of the luminous disk 40, when an external electrical signal is applied thereon to the first and the second conductive terminals 151 and 152, it will be delivered by the transparent electrode layer 136 and the metallic reflecting layer 133 to the upper surface and the bottom surface of the fluorescence layer 135 and make it luminesce.

[0049] The first and the second conductive terminals 151 and 152 could be placed on the surface of the disk lamination 11 or on the surface of the light emitting lamination 13 by through holes. The central portion of the luminous disk 4 could serve as a positioning mechanism for combining to an external luminous disk device.

[0050] FIG. 7(a) and 7(b) are the backside view and the front view of the luminous disk device of the first embodiment of this invention, respectively. The device 70 comprises a bracing apparatus 71 and a luminous disk 10. The bracing apparatus 71 includes a bracing portion 73, a stretching portion 72, and a contact portion 74. The bracing portion 73 contains a battery container which can accommodate at least one battery as a power supply of the luminous disk 70, the stretching portion 72 extends from the bracing portion 73 and is designed so as to be held by users; the contact portion 74 in the present embodiment is a pair of separable metallic pieces, its function is to combine the luminous disk 70 and the bracing apparatus 71 together, and conduct the battery power to the plural of conductive terminals of the luminous disk.

[0051] FIG. 8(a) and 8(b) are operational diagrams of the bracing portion and the contact portion of the first embodiment of the present invention. As shown in FIG. 8(a), when two buttons 76 each of which possesses spring thereon located at the opposing side positions of the bracing portion 73 are pressed, the two springs have the metallic pieces of the contact portion 74 drawn close to each other and thus become able to pass through the central hole of the luminous disk 10. After user passes the contact portion 74 through the central hole of the luminous disk 10 and let go the bottoms 76, the contact portion 74 recovers to the original separate state as shown in FIG. 8(b), thus the combination of the bracing apparatus 71 and the luminous disk 10 of the present invention is done. Moreover, because the metallic pieces of the contact portion 74 tightly contact with the plurality of conductive terminals of the luminous disk 10 when they recover to the original separate state, thus the power can be conducted to the luminous disk 10.

[0052] FIG. 9 is an exploded diagram of the bracing portion 73 of the present invention. The bottoms 36 control the movement of the contact portion 74 by elasticity of the springs 37. The battery container 75 can house at least one battery as the power supply of the luminous disk 10 of the present invention. The operation voltage of the present invention is between 60V to 150V, and the operation frequency is between 100Hz to 5KHz. Moreover, the power supply further connects to an inverter for transforming DC power to AC power, so it can provides a stable voltage and frequency to control luminescent variation of the electroluminescence layer of the luminous disk.

[0053] FIG. 10(a) and 10(b) depict a second embodiment of a luminous disk device of the present invention. The bracing apparatus 81 of the present embodiment is in an upright formation, which comprises a bracing portion 82, a contact portion 84, and a base 83. The combination of the bracing apparatus 81 and the luminous disk 10 can be used as an ornament on a table. The luminous disk device 80 does not use battery power, instead, it uses ordinary outlet as the power supply, and thus needs a rectifier for transforming DC power from the outlet to a particular AC voltage and current to replace the battery power.

[0054] Moreover, an aperture 86 provided on top of the bracing portion 82 so that a string can be passed through, and the luminous disk device becomes a necklace as shown in FIG. 10(c). Combined with the design on the surface of the luminous disk, the device can yet be regarded as a unique and stylish personal ornament.

[0055] FIG. 11(a) and 11(b) depict a front view and a back view of a third embodiment of a luminous disk device of the present invention, respectively. The luminous disk device 90 of the present embodiment comprises a luminous disk 10, a bracing apparatus 91, a plasticity mechanism 92 connected to the luminous disk 10, and a plug 93. The bracing apparatus 91 includes a bracing portion 94 and a contact portion 95 for holding the luminous disk 10. The plasticity of the mechanism 92, which is connected one end to the bracing portion 94 and the other end to the plug 93, allows users to create any shape they like from the device. Moreover, with the plasticity mechanism 92, the luminous disk device 90 can serve as a distant lighting device if the mechanism 92 is totally stretched out, this fact enables users to use the device 90 as a changeable lighting and decorating facility, and if necessary, stretching out for a distant use.

[0056] FIG. 12(a) depicts a fourth embodiment of a luminous disk device of the present invention. The luminous disk device 100 of the present embodiment is the same with (he one in the third embodiment except for the plug part. The plug 101 in the present embodiment is modified so as to fit into the socket in a car, as shown in FIG. 12(b). The design makes the passenger at the passenger seat, or even at the back seat able to read at nighttime without turning on the dome light, thus prevent the lightening dome light from interfering the vision of the driver.

The luminous disk device 110 comprises a luminous disk 10 and a bracing apparatus 112, and the bracing apparatus further comprises a stretching portion 114, a bracing portion 115, and a contact portion. The stretching portion 114 has a detachable case for housing at least one battery to be the power supply of the device 110, a switch 116 is also provided thereon. The bracing portion 115 extending horizontally from the stretching portion 114 is able to pass through the central hole of the luminous disk 10 for fixing the bracing apparatus and the luminous disk 10 together to be a luminous disk device 110 of the present invention. In FIG. 13(a), the contact portion is displaced on the top of the bracing portion 115 and has a talon 117 having metallic feet positioned corresponding to the conductive terminals on the luminous disk 10. The function of which is to conduct power to the plurality of conductive terminals. The feet of the talon 117 are elastic, so the feet of the talon 117 can contract inwardly when being squeezed for passing through the central whole of the luminous disk 10, and then recover to the original state; if the positions of the feet are correct, they are directly contact with the conductive terminals of the luminous disk 10 and able to conduct electricity.

[0058] Moreover, the formation of the contact portion can also be the one as shown in FIG. 13(b), a collar 118 that can be separate from the bracing portion 115; one side of the collar 118 has a plurality of contact points 119 corresponded to the amount of the conductive terminals of the luminous disk 10, and on the center of the same side is provided with an indentation thereon with the same diameter as the bracing portion 115. After the bracing portion 115 passes through the central hole of the luminous disk 10, the collar 118 and the bracing portion 115 can be fabricated by the tenon inside the indentation.

[0059] FIG. 14(a) and 14(b) are exploded diagrams of a sixth embodiment of a luminous disk device of the present invention. The bracing portion 121 and the stretching portion 122 of the luminous disk device 120 of the present embodiment are made coaxial, that means the bracing portion 122 extends coaxially from the bracing portion 121. The design makes the whole device smaller and thus more convenient for user to carry.

[0060] FIG. 15(a) and 15(b) are exploded diagrams of a seventh embodiment of a luminous disk device of the present invention. The device 140 of the present embodiment has a detachable disc base 141 on the bottom of the stretching portion 114, thus the device can be either hold by hand or put on a table.
