Description

M246604 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to the structure of a light-guiding column, especially a structure of a light-guiding column composed of a cylinder and a block. The cylinder and block system can reflect The received light source, and the visible area of the block can obtain the auxiliary light source by the area where it is projected, so that the visible area can observe a more uniform light source. [Previous technology] Caiwen 'Light Emitting Diode (LED for short) is based on III-V or II-VI compound semiconductors (GaAs'GaP'AlxGal-xAs, ZnSe ...) Made of p / N diode with light emitting function (Light Emitting). The principle of its light emission is to combine the electrons and holes of the N-type and p-type semiconductors under a forward bias. The electrons generate excess energy due to the energy conversion level of the electrons and emit photons to emit light. The current passing through the power source is not k. / f supplements electrons and holes to N-type and p-type semiconductors, so that "the combination of electrons and holes emits light" continues, and the LED continuously 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 heat energy. Therefore, LEDs are a kind of cold light emitting element. Compared with incandescent light bulbs that rely on heat energy, the advantages of Led are: heat generation Less, long life, low power consumption, monochromatic light emission, fast response speed, impact resistance, good weather resistance, small size, easy to compact and lightweight, etc. In the field of visible light, in the initial and current major applications, LEDs are used to replace small incandescent bulbs into various application markets (such as home appliances, negative §fl products, communication products, indicators, backlights, etc.), Highlight later

Between the faces, there is-a light guide column 1 (as shown in Figure i), the light guide table; one end is exposed on the surface of the casing, and the other end faces the LED, so that the LED V = ΪΪ ; Ϊ = inside the light guide 1 ', and after being refracted by _, it was led to ¥ by the light guide! It protrudes from one end of the surface of the case, and projects the light to the outside. However, whether the light guide column 1 projects light in a single direction or in multiple directions, if a user views the light guide column from different angle positions, the projected light may have uneven brightness or overflow light. Many inconveniences and troubles.

M246604 IV. Creation Instructions (4) [Implementation]

This creation is a structure of a light guide column, as shown in FIG. 3, a column 2 is provided, a block 3 is provided at one end of the column 2, and a part of the block 3 is the block 3 Viewable area a, and view the visible area A from any angle on the surface of the block 3, the viewable area a can be projected into the block 3, and the other end of the carcass 2 can receive a light emitting element 4 (Such as a light-emitting diode) project a light source on it. The light source is continuously reflected in the column 2 and can be guided into the block 3 and reflected repeatedly in the block 3 to Guide the light source to the viewable area A, and whether the viewable area a is viewed from any angle, the viewable area A can be projected into the block 3, so that the viewable area a can pass through the area where it is projected ' And the auxiliary light source is obtained, so that a more uniform light source can be observed in the viewing area A. In particular, the two ends of the viewing area A will not cause a shortage of light sources.

In a preferred embodiment of the present invention, a position 'of the block 3 facing the column 2 is provided with a first inclined surface 30. Thus, when the light source guided by the column 2 is directly reflected to the When the block 3 faces the column 2 (that is, the first inclined surface 30), the light source can be reflected to other areas of the block 3, so that the light source can be better within the S block 3 In addition, the pillar 2 faces one side of the light-emitting element 4, and at a position adjacent to the first inclined surface 30, a surface gradually facing away from the block 3 facing the light-emitting element 4 is provided. Close to one of the second inclined planes 20 ', the light source guided by the cylinder 2 will be reflected on the second inclined plane 20 to the block 3, and because there is reflection on the second inclined plane 20 Light source 'when the user goes down vertically from the highest point of the visible area A

Page 8 M246604 IV. Creation instructions (5) Look, the viewable area A can be projected on the first inclined surface 30 and the second inclined surface 20, so that the visible area A can obtain the first inclined surface 30 and the second inclined surface 2 〇The light source of the projected area allows the user to observe a sufficient light source from the viewable area A, and the highest point of the viewable area A will not be insufficient. In this embodiment, the viewable area A is matte or bite-shaped, so that the light source reflected to the viewable area A can emit light uniformly, and the remaining area of the block 3 except the viewable area A is And the pillar 2 needs to be mirror-shaped, so that after the light source received at the other end of the pillar 2 is projected into the pillar 2, the light source can be completely reflected in the pillar 2 and the block 3, and furthermore, In order that the pillar 2 can concentrate the light source projected by the light-emitting element 4, the other end of the pillar 2 is concave lens shape, so the light source projected by the light-emitting element 4 will be used by the pillar. The other end of the body 2 concentrates light. In order for the user to see from the front of the block 3, he can see that the block 3 emits sufficient light sources, so that the lowest point of the visible area a will not have insufficient light sources. In this embodiment, the The pillar 2 faces away from one side of the light-emitting element 4, and at a position adjacent to the block 3, a bump 34 is provided. The bump 34 can provide the light guided by the pillar 2 to reflect to other positions. And, the light source reflected on f can be used as an auxiliary light source to provide the visible area A, so that the light source can be observed at the lowest point of the visible area A. In another preferred embodiment of this creation, please refer to Figures 2 and 3. 4 The structure is also provided with a base 5, and the base 5 is provided with at least one pillar. There is a fitting element 50, so that the base body 5 can be fitted into the housing 6 of an electronic product by coupling the π piece 50. In addition, the base

M246604 IV. Creation Note (6) When the light source reflects to the position where the base 5 and the pillar 2 are connected, the light source is not easily transmitted to the base 5 and the light overflow phenomenon can be avoided. In this embodiment, a limiting block 32 is provided on one side of the block 3 opposite to the viewable area a, and the limiting block 32 cooperates with the casing 6 so that when the structure is installed in the casing 6 At this time, the structure can make the block body 3 not protrude from the outside of the housing 6 by matching the limiting block 32 with the inner wall of the housing 6. With the composition of the above-mentioned components, the visible area A of the structure, regardless of the user's viewing position, the light projected by the visible area A will have a uniform light without uneven brightness or Spill light icon. Also, the base 5 may be provided with at least one post 2, so if the electronic device changes the design of its housing 6 or increases the number of LEDs, as long as the length of the base 5 is extended, and the base 5 It is only necessary to add a column 2 to the body 5, without having to greatly change the structure, which can save manufacturing costs. According to the above, it is only one of the best specific embodiments of this creation, but the structural characteristics of this creation are not limited to this. Any person familiar with the art can easily think of changes or modifications in the field of this creation. Both can be covered by the patent scope of this case.
