Disclosed is a polycarbonate resin composition obtained by blending a specific amount of an acrylic resin (B) having a specific viscosity average molecular weight or a specific amount of a polyorganosiloxane into a polycarbonate resin containing a polycarbonate copolymer (A) having repeating structural units represented by the general formulae (I) and (II) below. This polycarbonate resin composition enables to obtain a molded body having good light conductivity and being free from yellowing due to thermal deterioration, even when it is molded into a large-sized light guide member or light guide plate.

The invention discloses a condensation type light-guide concrete structure unit and a construction method of a light-pervious wall. Condensation type light-guide concrete is formed by making a plurality of condensation type light-guide pipes penetrate through self-compacting concrete. Each condensation type light-guide pipe is composed of a light inlet end, a middle light-guide pipe body and a light outlet end, and the light inlet end is composed of a convex lens and a circular truncated cone-shaped prism. The construction method of the light-pervious wall based on the condensation type light-guide concrete structure unit comprises the following steps that S1, the multiple condensation type light-guide concrete structure units are manufactured; and S2, the condensation type light-guide concrete structure units are spliced in sequence to form the integral light-pervious wall. The condensation type light-guide concrete structure unit has the advantages that the light guide performance is good, the mechanical performance is high, materials are saved, manufacturing is easy and convenient, and the application prospects are wide.

A micro-structure light guide plate and an edge type backlight module, the micro-structure light guide plate comprises: a smooth surface, an inner surface with a roughness surface opposite to the smooth surface, and a light incident surface connecting the smooth surface to one side of the inner surface. The height H of the micro-structure of the smooth surface is 60-150[mu]m, a micro-structure pitch is P, and H / P is 0.25 to 0.5. The inner surface includes a first area having a printing structure on the surface, and a second area not having a printing structure on the surface. Through the roughened inner surface cooperating with appropriate area distributed printing structures, the light guide plate is enabled to have a good reflection effect, and the amount of printing ink is reduced, costs are lowered, and the roughened inner surface may make scratches on the plate looks not obvious with the effect of covering defects, eliminating the use of protective film.

The present invention provides a fabric, a lighting device, a curtain, a staircase lighting device, a bag, a speaker device, a monitor, a collar, shoes, and a portable terminal. By design, in a complex and highly designed fabric that has an area where the optical fiber is located on the surface of the fabric and emits light, and a fixed area that is hardly exposed on the surface and is hidden, the bending and pressure of the optical fiber are reduced as much as possible, and Good light guide. The fabric includes: a fixed area, which holds the optical fiber as the seventh fiber; and a light emitting area, which has the optical fiber as the seventh fiber and emits light. , braided with the 3rd fiber, the 4th fiber and the 5th fiber; and the above-mentioned optical fiber is arranged in the space of the middle layer between the above-mentioned surface layer and the above-mentioned inner layer.

The invention discloses a bent glass light guide plate preparation method. Light guide screen dots can be printed through high-temperature-resistant printing ink before curved surface formation of plate glass. The method is simple in printing process and high in quality, and can enable a light guide plate to keep good light guide performance after formation; and the technical defect caused by a mode that a curved surface is formed first, and then, the light guide screen dots are printed in the prior art is overcome.

The invention discloses a flexible LED strip-shaped lamp with integrated light guiding pieces. The flexible LED strip-shaped lamp with the integrated light guiding pieces comprises a flexible strip-shaped LED light source and a flexible covering layer covering the flexible strip-shaped LED light source. The flexible strip-shaped LED light source is formed in the mode that multiple LEDs are welded to a flexible strip-shaped circuit board. The flexible LED strip-shaped lamp is characterized in that the covering layer is provided with the light guiding pieces protruding from the outer surface of the covering layer, each light guiding piece corresponds to the corresponding LED, the light guiding pieces are independent of one another, and the light guiding pieces and the covering layer are of an integrated structure; The invention further discloses a manufacturing method of the flexible LED strip-shaped lamp. According to the manufacturing method, the light guiding pieces are formed on the covering layer through the cutting technology or the mold-injecting technology or the mold strip technology or the extruding technology. The flexible LED strip-shaped lamp with the integrated light guiding pieces has the advantages of being firm in structure, excellent in light-guiding effect, excellent in light diffusing effect, good in waterproof effect and capable of achieving a good point light source effect.
