Description

M22U2D ^ ___ 4. Creation instructions (1) [Technical field to which the new type belongs] This creation is a light guide structure, especially a type installed in an electronic device, which is composed of a block and a post to block And to prevent the light source from emitting light scattering or overflow phenomenon, and clearly transmit the light source to the outside of the electronic device. [Previous technology] According to the light-emitting diode (Light Emitting Diode, abbreviated as: LED) is based on ιι-ν or π-VI group compound semiconductor ((; "3, GaP, AlxGa ^ xAs'ZnSe ...) as the material, so Made of P / N diode with light emitting function (Ught Emitting). The principle of light emission is to combine electrons and holes of N-type and P-type semiconductors under forward bias, because the electron conversion energy P White produces excess energy and emits photons to emit light. The current passing through the power supply continuously supplements electrons and holes, giving N-type and p-type semiconductors, so that "the combination of electrons and holes emits light." From this principle, it can be seen that the principle of LEDs relying on electronic energy level conversion is different from the principle of traditional incandescent light bulbs relying on thermal energy, so LEE) is a cold light emitting element. Compared with incandescent light bulbs relying on thermal energy, the advantages of LEDs There are: low heat generation, long life, low power consumption, monochromatic light emission, fast response speed, "collision resistance, good weather resistance, small size, easy miniaturization and light weight, etc. In the field of visible light, The main application In use, LEDs are used to replace small incandescent bulbs and cut into various application markets (such as home appliances, information products, communication products, indicators, backlights, etc.). Later, high-brightness products have been developed and commercialized, and expanded. Its application areas, such as automotive

Lights, large outdoor Kanban ##, high-brightness inGaN materials are expected to be developed, and the development of high-brightness white LEDs has been promoted. In the future, LEDs will be used in the lighting field, which is regarded as a major life in the lighting market. Thousands of LEDs are used for the instructions of the above-mentioned devices, and are provided on the circuit board, and the surface of the housing of each device is suspended with = female: one or two :: the structure of the guide pillar. The structure is provided with a u body. The base body is provided with at least one outwardly extending green lead pillar connected to the LED at one end. The other end is connected to a panel of an electronic device, so that the light sources emitted by the LEDs can pass through. The guides of these light guide columns are displayed on the panel, and one side of the base body is provided with a first! Two: To set the y-fitting element of the yam melon, through the first fitting element of the first body and the second fitting element of the first body, the two bodies are connected to each other: To display the number of LED light sources, the light guide columns with phase number 4 and number 1 are connected together by their bases. : δ Xuan light guide structure, whether it is a single direction or multi-directional projection of light two right users from different angle positions 'viewing there will be uneven brightness or overflow phenomenon, = method' evening and trouble, because of the message There are many types, often helmets :: le〇T ^ L :, 'Because the distance between LEDs is too close, it often causes the light sources to interfer with each other: :: Ϊ above colors are mixed together, ⑨ two or more colors are displayed at the same time, P㈢Xe becomes The display is unclear, which often causes the user to display the message incorrectly.

M271120 IV. Creative Instructions (3) Judgment. The conventional improvement method is using a light-shielding rib. The improvement effect is not obvious. There is also a transmission of LED distance / source. However, this method requires circuit board and appearance. σ in order to prevent the phenomenon of light transmission when the light source is too bright, a, and when the LED light improvement method has not been able to completely solve the problems of interference and light transmission ^ and [new content] the structure of the beam of light after too long 'The structure is provided with a system in which the block system is closed at one end of the block and is inserted into the casing, so that the light source of the light-emitting element of the electronic device is subjected to the column-shaped housing structure and structure. In view of this, the embodiment is Improve the shortcomings of customary use, research and experiment with authors, and finally develop a g structure of this creation.之一 One of the purposes of this creation is to provide a light-guiding rod tied to a circuit board inside an electronic device, and the circuit g is a light-emitting element. The structure includes a block and a pillar, which are opaque and designed. On the circuit board, the light-emitting element can be inserted into the body, and the pillar system is plugged into the block, and the other end of the pillar body extends to the light emitting device provided in the electronic device. The light source emitted by the component is guided to the outside through the cylinder to display the light source. In this way, the block can block the interference caused by the diffused or penetrating light source and guide the body, The light source is clearly displayed outside the electronic device. In order that the review committee can further understand and understand the purpose, shape features and effects of this creation, with the drawings, the details are as follows:
