Abstract
A light-guiding cover structure includes a top cover unit and a light-guiding unit. The top cover unit has a plurality of receiving spaces formed therein. The light-guiding unit includes a plurality of light-guiding groups, wherein each light-guiding group includes a plurality of optical fiber cables received in the corresponding receiving space, and each optical fiber cable has two opposite ends exposed from the bottom surface of the top cover unit and respectively facing at least one light-emitting device and at least one light-sensing device that have been disposed under the top cover unit. Therefore, the optical fiber cables received in the corresponding receiving space, thus when the light-guiding cover structure is applied to the LED package chip classification system, the aspect of the LED package chip classification system can be enhanced.
