However, due to the total reflection effect of the existing LED in the thick-walled light guide, the light will not leak from the side wall of the light guide, and finally most of it will be emitted on the light-emitting surface. The light emitted from the LED cannot be seen, and the entire thick-walled light guide is a slightly luminous transparent crystal when viewed from above. The thick-walled light guide of the lamp only constitutes a luminous pattern as a whole, and does not have details to strengthen its own characteristics. Single, for this reason, we propose a component and method for displaying patterns or characters on thick-walled light guides

The invention relates to an assembly and method for representing patterns or characters on a thick-wall light guide. The assembly comprises an LED light source and a thick-wall light guide,. Light guide optical patterns are arranged on the side wall of the thick-wall light guide. The light incident surface of the thick-wall light guide is in a smooth curved surface shape. Light guide optical patterns are arranged on the side face of the thick-wall light guide and have a total reflection function; and then the light rays are propagated in the thick-wall light guide in a vertical and small-amplitude peripheral diffusion mode, so that the characteristics of light guide optical patterns and the like are displayed. The light rays pass through the thick-wall light guide optical patterns to collimate the light rays in the vertical direction, and the collimated light rays are propagated in the thick-wall light guide. According to the invention, the thick-wall light guide is collimated on the use curved surface and then is comprehensively reflected, so that light rays can be reflected to the optical patterns, the optical patterns can be better and fully displayed, and thus the light sourcecan be utilized to the greatest extent for comprehensive reflection. The purposes of enhancing self details and beautifying the appearance can be achieved.
Description
technical field [0001] The invention relates to the technical field of thick-walled light guides, in particular to a component and method for displaying patterns or characters on thick-walled light guides. Background technique [0002] At present, thick-walled light guides are a representation method that is often used in various lamps, and with the rapid development of the field of thick-walled light guides, more and more demands are met. However, due to the total reflection effect of the existing LED in the thick-walled light guide, the light will not leak from the side wall of the light guide, and finally most of it will be emitted on the light-emitting surface. The light emitted from the LED cannot be seen, and the entire thick-walled light guide is a slightly luminous transparent crystal when viewed from above. The thick-walled light guide of the lamp only constitutes a luminous pattern as a whole, and does not have details to strengthen its own characteristics. Single...
