Description

535385 V. Description of the invention (1) [Technical field] The present invention is a kind of very few point light sources used in electronic products. [Previous technology, traditional 1 (please refer to section 9 4 is provided with a light guide plate 9 as a light at the bottom. 2 decreases to The light guide plate's lack of exemption plate 9 2 bis. The side light guide plate 9 2 overcomes the problem of single light, that is, someone is shown in FIG. 6. However, most of the electronic products that must be often charged are illuminated by 9 5. In the case of the keyboard and the largest source set in the above guide, the light guide plate source 9 3 shown in the figure 5 has a light source 9 9 2 and the middle two side guide source 9 3 is provided on the liquid crystal mobile light source 9. The light plate of 5 is 9 and the light is displayed on the day) with 9 2,, but 3 is directly on the front edge, which can be seen, if it is drawn, it is used as the module 9 phone) 3 It is often important to use the product to enter the function. There are 2 on the bottom. Phase source 9 3 relates to a light guide plate with a keyboard light emitting function, especially a light guide plate with a light guide structure at the periphery of the screen and the keyboard for the purpose of displaying the lighting effect. For the sake of degree, (the light source is the brightest light source with the highest degree of brightness. 9 The light structure is uniform. The degree and the average number of degrees and the average amount are over a lot of hemp, especially to overcome 3, and the electronic products they manufacture are: It is bright enough and the brightness of the part raised by LEDLED is often to the periphery. In addition, it will not be clear without good conduction brightness, often the periphery of bright 4 is set to supplement the brightness and generate power consumption, the keyboard 9 5 is generated Therefore, most light sources 9 also have more power consumption, so that the display 9 is a point light source such as a liquid crystal module diode), so it is strong and gradually approaches zero. For the lack of uniformity of the light source 9 3 (the problem of uniformity, annoyance; of course, the problem of key lighting in the dark and other light sources 9 3)
