V. INSTRUCTIONS (2) The existing LED light guide columns are mostly made of polycarbonate (pc) material, and the LED light source is guided to the plastic panel by utilizing the characteristics of good transparency of the PC. However, the disadvantages of this method are as follows: U) The longer the distance between the LED and the plastic lamp housing, the more severe the attenuation of the light source, and the brightness is difficult to control. (2) The longer the distance between the LED and the plastic lamp housing, the larger the space occupied by the LED light guide column, so the thickness of the plastic panel is thickened, which increases the difficulty of the I D design.

(3) Based on the physical characteristics of light, the angle of the corner of the LED light guide of % material should not be too small (ex· can't be less than 90). Otherwise, there will be light scattering problem, so it will increase the difficulty of wiring the LED light guide column. degree. Therefore, since the angle of the light guide column should not be too small, if the LED position of the server casing is perpendicular to the vertical distance of the plastic lamp housing on the panel, the light guide column will be very large, so that the design must make the panel The increase in thickness can obscure the volume of the light guide column. As the distance is farther away, the brightness of the LED is attenuated, i increases the thickness of the panel and increases the cost, which is the biggest problem in the industry.

Therefore, how to solve the above problems and propose a novel light guiding structure for the LED of the server panel, not only can improve the shortcoming of the traditional LED light source attenuation, but also reduce the thickness of the panel and reduce the manufacturing cost and increase the aesthetics, 'for a long time It has always been the user's eagerness and hope that the inventor is here, and this person is based on years of experience in research, development, and sales of related products, thinking and improving ideas, and his personal expertise. After multi-party research design and topic discussion, I finally developed a server for server.
