Problems solved by technology

There is still room for improvement in the amount of light guided by the rolled parts manufactured by these traditional processing technologies, and then the light guide components manufactured
In addition, with these traditional processing techniques, if the corresponding microstructure is formed on the rolled piece is more complicated, the processing process is more complicated and the cost is higher
Moreover, if the corresponding microstructures are only formed on a few positions (non-comprehensive distribution) on the rolled piece, the traditional processing technology is not accurate enough in alignment

Abstract

The invention discloses a rolling piece, a light guide component and a method for manufacturing the light guide component. The rolling piece comprises a cylinder and a metal sheet. At least one hole is formed in a working surface of the metal sheet. An annular protruding platform adjacent to the edge of an opening of the hole is arranged on each hole. The cross section of each annular protruding platform is approximately trapezoid or approximately triangular. A combination surface of the metal sheet is combined on the external circumference surface of the cylinder, so that the working surface faces outwards. The light guide component manufactured from the rolling piece is high in guide light quantity. In addition, the light guide component is manufactured from the rolling piece, so that the advantages of accurate alignment, high precision, high efficiency and low cost are achieved.

Description

technical field [0001] The present invention relates to a rolled piece, a light guide component and a method for manufacturing the light guide component, and in particular to a rolled piece capable of manufacturing a light guide component with a high amount of guided light output, and a light guide made using the rolled piece. Component and method of manufacturing the light guide component. Background technique [0002] The backlight in the luminous keyboard, the backlight in the liquid crystal display, and even the lighting equipment all need to install light guide components, such as brightness enhancement film, diffusion film, or light guide components that guide light to specific positions. [0003] Currently, many light guide components have been manufactured by roll-to-roll process. Because the roll-to-roll forming process has high production efficiency and low production cost, it is gradually used in mass production of light guide components. The roll-to-roll formin...
