__ £ ^ __ B7U9l600. 5. Description of the invention (1) [Scope of the invention] The present invention provides a method for manufacturing a light-storing button, especially it can integrate a light-storing agent into the silicon button or its surface so that it can absorb light at any time. The light is stored, and it can emit light spontaneously in the battlefield or in a place with insufficient light to facilitate the use of buttons. [Background of the Invention] In order to use the buttons on sfl products (such as mobile phones, fax machines,.. _, Etc.), the numbers, characters or patterns on the buttons can be clearly distinguished at night or in a low-light environment so that For operation, a light emitting diode (hereinafter referred to as LED) is traditionally provided inside or next to the key, so that when the LED is powered on, the LED can emit bright light to illuminate the numbers or characters on the key. At present, some are made of transparent thin rubber material, and the keys are combined with the bottom of the cover to enable the light preset in the keyboard to illuminate the text or pattern symbols through the keys and the cover, thereby providing night or lack of light. It is also easy to use under the environment. As shown in Figure 2, the conventional silicone button is formed by a light-transmissive silicone material into a button 1 with an inner space at the lower end, and a conductive member made of a conductive material is combined with the lower end of the button 1 outside the inner space. Part 12, and i 3 is printed on the top surface of the button 1 with printed characters such as characters, numbers or patterns; in addition, the position where the button 1 is to be installed on the circuit board 2 is provided with 1Ed for conductive contacts 21 in advance, so that the button When 1 is provided on the circuit board 2, the conductive part 12 is made to correspond to the conductive contact 2 and the LED 3 is accommodated in the space below the key 1. When the key 1 is pressed, the conductive part i 2 can be made. Contact the conductive contact 21 and energize it to transmit signals. After releasing the button i to return it to its original state, the conductive part 12 is disconnected from the conductive contact 21 and the power is cut off. The circuit board,

Description of the Invention (2) The circuit provided additionally provides the power required by the LED3, which can be set to automatically provide LED3 power when the communication product is in use. It emits bright light and passes light through the light-transmissive button 1 so that the characters, numbers or symbols on its surface can be clearly seen. Another conventional button with a lighting function is shown in FIG. 3, except that a conductive portion 1 2 ′ corresponding to the conductive contact 21 on the circuit board 2 is provided at the lower end of the button 1 and a printing is printed on the upper surface thereof. In addition to the target 13, an LED 3 is directly arranged on the circuit board 2 outside the button 1, so that the LED emits light after the current passes through and directly illuminates the upper surface of the button 1 to achieve identification. However, 'the above two traditional keys with light-emitting functions all use the bright light emitted by the LED to achieve the lighting function, but the installation of ED on the circuit board increases the complexity of the manufacturing process and the manufacturing cost is high; The power consumed by the LED is not much, but it is still a burden when it is used for a long time and in large quantities. Therefore, the present invention is to improve the lack of the traditional button described above. [Summary of the invention] The main purpose of the present invention is to provide a method for manufacturing a light-storage button, which directly combines the light-storage agent with the silicone button itself so that it can absorb light in an environment with sufficient light. To save energy consumers. Yet another object of the present invention is to provide a method for manufacturing a light-storing key, by directly combining a light-storing agent on the surface of the key so that it can absorb light in an environment with sufficient light, and then release bright light when the light is insufficient, And have to reduce manufacturing costs accordingly. Based on this ’the method of manufacturing the light-storage button provided by Ben Mengming is

Description of the invention (3) The light storage agent is added to the solid and soft state of the silicone material and mixed, and then injection molding, so that the entire key has a The light-storing effect is to add a light-storage agent to the liquid Shixijiao, and then print the silicon rubber on the surface of the key by printing to form a light-storing key. Other objects and functions of the present invention will be further understood after further explanation in conjunction with the following drawings. [Explanation of the embodiment] The manufacturing method of the light-storage button provided by the present invention is mainly to directly combine the light-storage agent with the silicone button so that it can absorb light in an environment with sufficient light. When the light is insufficient or in a dark environment, Release the absorbed light | 'for easy identification during use. There are two ways to bind the light-storage agent :: = button: 纟 中-the system is to add the light-storage agent (through Πi to the solid state soft rubber material, and glue it by the roller to make the light-storage agent combine). Then the fragmentation has a light-storing effect, and then other === characters are bluffed on the key. In this way, the key itself can be used to generate the ==, which can easily identify the text, numbers on the key, or the key below the key. The conductive part is used on the circuit board, and the conductive contact of the button is used, so that after the button is pressed, the conductor 2 should be connected to the conductive part contact to create a path. In one embodiment, the stored silicone material can be ordered and mixed with a stirrer. The liquid light-storing ink is added first, and then the mixed light-storing ink is changed from printable to printing. — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — ————————————————————————————— One embodiment, is an example, which is to store the silicone material and mix it with a stirrer, first add the liquid light-storage ink, and then change the mixed light-storage ink from printable —-______ by stencil printing

Description of the Invention (4) Print it on the surface of the general key 1 (or silicone key), and bake it 'on the light storage ink 丨丨 It is printed with fonts or symbols such as numbers and characters. The light-storage button is formed by the light-storage effect of the light-storage ink 1 1, which also achieves the purpose of facilitating identification in a battlefield or in a low-light environment. Below the button 1 is provided The conductive part 12 and the conductive contact 21 of the part 12 cause the key that is generated by pressing the contact to the conductive contact 21 to pass through the path 'using the light storage agent to absorb light in the ground' and press the key when the light is insufficient The surface is conducive to operation and use; and the power consumed by the LED and the cost-effectiveness are in line with the requirements of the invention patent. The foregoing are only used to explain the attempt to make any form of the invention in accordance with the spirit of the invention. The hair should include the conductive part 12 after the fan button 1 intended to be protected by the present invention. By using the method of the present invention, the light is released naturally and naturally in an environment with sufficient light to supplement the lighting. With this design, the vehicle can be serviced. Therefore, the present invention is a preferred embodiment of the present invention. Therefore, any modification or change that is not clear is = phase domain. ‘All still
