| description | The invention discloses a light guide plate used for an LED module and a manufacturing method thereof. The light guide plate has a rectangular structure, and one side surface or two side surfaces of the light guide plate are provided with LED light sources; screen dots are printed on the bottom surface; and a light path is changed by arranging an inclined surface on the side opposite to a light source of the light guide plate or forming a V-shaped groove on at least one of an upper side surface and a lower side surface and matching the screen dots arranged on the bottom surface of the light guide plate so that light utilization ratio is improved, the number of LEDs under the same conditions is reduced, and the aim of saving energy is fulfilled. The method is suitable for large batch production, ensures the consistency of products, and is easy to popularize. |
