Novel 3D special-shaped light guide device and manufacturing method

Abstract

The invention discloses a novel 3D special-shaped light guide device and a manufacturing method. The novel 3D special-shaped light guide device comprises an arc-shaped transparent substrate and LED light sources arranged on one end or both ends of the transparent substrate, wherein the end surfaces of the transparent substrate are arranged in a manner of directly facing the LED light sources, the end surfaces are light incident surfaces, the upper surface of the transparent substrate is a light emergent surface, the lower surface of the light emergent surface is a light guide surface, a plurality of light guide points of optical nano microstructures are arranged on the light guide surface, the light guide points are formed by heating and extruding the transparent substrate via a mold provided with concave optical nano microstructures, other non-light-emergent surfaces can be screen-printed with exquisite patterns, more exquisite graphic textures can be exhibited with the cooperation of luminous decorations, a protecting film layer is arranged between the upper part of the light guide surface and the lower part of the light emergent surface, the light guide surface can cooperate with planar printed graphics, and other edges, except the light incident surfaces, of the transparent substrate are adhered with reflective films. The novel 3D special-shaped light guide device can enhance the brightness of lamps under the requirement of same power, can achieve the pattern luminous decorative effect, can be designed freely according to requirements of the designer, and is rich in effects, high in processing speed and low in cost.

Description

technical field [0001] The invention relates to the technical field of light guide devices, in particular to a 3D special-shaped light guide device and a manufacturing method. Background technique [0002] The light guide plate is a component used in the backlight module to guide light. It transmits the light provided by the light source to the remote side of the light guide plate through the principle of total reflection, and uses several optical structures arranged on it to destroy the total reflection of light. , to guide the light to the light-emitting surface to form a uniform surface light source. [0003] The traditional method used to form the optical structure of the light guide plate is to directly form dots on the light guide plate through the designed optical structure pattern through screen printing or laser engraving. The ink viscosity is not easy to control and the size of the optical structure is limited due to the characteristics of the ink, which in turn a...
