Description of the invention: [Technical field to which the invention pertains] 'The present invention provides a circuit board structure capable of self-illumination, especially a circuit board structure available for production - illuminating to externally, by means of a circuit board The inner side is provided with a light-emitting portion, which can be concentrated and laterally projected into the circuit board to improve the performance of the circuit board. [Prior Art] ^ At present, in this era of technological advancement, electronic products have brought people a convenient environment. However, most of the inductive electronic products have to be pressed to enter text, numbers or ages. Such as the mouse, health or the rocker and light grab for the game, but as the product changes with each passing day, the buttons need to be changed according to different needs, for example, from the keys used in the keyboard of the early desktop brain to The difference between the keys used in the notebook computer is quite large. The ® notebook computer emphasizes that it is light, thin, short, and small, so the press of the key is not like the keyboard of a desktop computer. In accordance with the characteristics of the above notebook computer to change, such as the phone button can not be illuminated, but people will use the mobile phone in the dim light, but can not accurately press the desired button, so there is Weishang proposed an improvement for this problem, so that the button can emit a light source for people to use. Please refer to the thirteenth figure, the illuminated keyboard is a keyboard part a, a backlight device b The keyboard portion a has a circuit board A2 ′ above the bottom plate a 1 and a light emitting 201029525 component A21 with a downward emitting light source on the circuit board a 2 , and a plastic material with an elastic component A31 above the circuit board a2 . The film A3 is connected to the bottom plate A1 via the connecting mechanism A4. The button A 5 ' is further disposed under the bottom plate A 1 of the keyboard portion A, and the light guide plate B1 is disposed under the light guide plate b1. Reflector b 2 . The light-emitting element A21 of the circuit board A2 is a downward-emitting light source. The light source passes through the bottom plate A1 and is irradiated to the light guide plate B1 of the backlight device b. The light guide plate B1 projects the light source to the reflection plate B2, and uses the reflection plate B2. After the reflection light source Φ, the light guide plate B1 and the keyboard portion A are sequentially passed through, so that the button A 5 at the top of the keyboard portion A has a bright light appearing, but the keyboard component a and the backlight device b have a plurality of components. The thickness of A combined with the backlight device B increases, and there are still many defects in actual use, such as: (1) The light-emitting element A21 of the circuit board A2 undergoes multiple reflections and refractions after being emitted downwardly, and finally The light is projected to the button A 5 'after the light source has been reflected many times', which will cause the light to be mixed, and reduce the brightness of the light source, resulting in loss of light. The light at the button A 5 is also less effective. (2) The thickness of the keyboard unit A plus the backlight device b increases, which is unsuitable and conforms to the design requirements of light, thin, short and small electronic devices, which will lead to an increase in the thickness of the keyboard of the electronic device. The thicker 〇(3) keyboard A is provided with a plurality of axle bases on the bottom plate A 1 , and each axle seat needs to pass through the circuit board A 2 to be assembled by the connecting mechanism A 4 , resulting in 4 201029525 circuit board A2 Through the provision of a plurality of perforations, the spatial position of the line layout can be greatly reduced, and it is difficult, time-consuming and labor-intensive to design and manufacture. - (4) If a plurality of films are provided on the circuit board A 2 of the keyboard portion A, and a power supply circuit and a signal transmission circuit are respectively disposed on different surfaces of the film, although it can be used to solve the lack of space shortage, Multiple processing is performed to set up a variety of circuits, resulting in a significant increase in manufacturing costs. The above-mentioned circuit boards used in the illuminated keyboards have many problems and deficiencies, which is the object of the inventors and those in the industry who want to improve. SUMMARY OF THE INVENTION Therefore, in view of the above-mentioned deficiencies, the inventors have collected relevant information, and through multi-party evaluation and consideration, through continuous trial and modification, the design of such a permeable® lateral projection light source is designed in the circuit board to effectively improve The birth of the invention patent for the circuit board structure of the self-illuminating circuit board. The main purpose of the present invention is that the circuit board is made of two substrates of light transmissive material, and one or more light guiding portions for uniformly transmitting light are disposed on the circuit board, and one or more light emitting portions are erected. The circuit layer is fixed on the circuit board for lateral projection of the light in the circuit board and then projecting outward through the light guiding portion, and the light emitting portion is disposed between the circuit boards and electrically connected to the circuit layer. Within the circuit board, the light-emitting portion is laterally illuminated to concentrate the bright light 5 201029525 and then projected outward by the light guiding portion, thereby reducing the optical loss phenomenon and gaining the brightness of the circuit board. The secondary object of the present invention is that the circuit board is made of a light-transmissive material and the opposite thickness of the two substrates are different, and the thickness of the upper substrate can be thinner than the lower substrate (the upper substrate can also be slightly thicker) In the lower substrate), one or more light guiding portions for uniformly transmitting light are disposed in the lower thick substrate, and more than one light emitting portion may be erected, and the light emitting portion may be a surface-adhesive β-type light emitting diode The polar body (LED) is disposed in an upright substrate in an upright manner.

The connecting portion 21 extending to the outside of the circuit layer 2 (see the ninth, eleventh, and eleventh views), and the power line of the light emitting portion 121 may also extend out of the outer side of the circuit board 1 and be connected to the circuit layer 2. When the side of the portion 21 is directly electrically connected to the external power source, the light-emitting portion 121 can be transmitted through the circuit layer 2, and the light can be emitted in the lower substrate 12, and the light guide can be projected onto the light guides in the human substrate 1 2 . The portion 12 is located at 2, and the light source is uniformly projected outward through the light guiding portion 12 2 and the light emitting portion 121 is present The lateral illumination enters the substrate 12, so that the light can be scattered toward the periphery of the towel, and the light source is uniformly projected by the light guiding portion 12 2 through the upper substrate 11 to be outwardly projected, which can be 7 201029525 The light-emitting efficiency of the circuit board 1 has a good light-emitting luminance and constitutes the structure of the circuit board 1 of the present invention. The two oppositely stacked substrates 1 丄 and i 2 of the circuit board 1 may have thicknesses different in thickness, and the thickness of the upper substrate ii is thinner than the thickness of the lower substrate 12 (the upper substrate may also be used).
