Abstract: Long remaining illuminant source transforming wavelength including illuminant absorption color powder and InGaN ultraviolet emission chip. The invention is presented in form of container modeling, which is made from plastic colophonium (for example epoxy resin, acrylic resin and silica gel.) and illuminant absorption color powder. The container is fitted with an InGaN ultraviolet emission chip that contains DC power source connection. The illuminant absorption container made of illuminant absorption color powder and transparent or semitransparent colophonium is with the build-in InGaN ultraviolet emission chip connecting to the power source enables the material color powder to absorb and liberate the illuminant constantly. Hence to deliver a brighter, clearer and long lasting lame illuminant. In addition, lame illuminant is delivered in flat form hence enhance the conduct and glowing of illuminant.

Abstract: A method is used to produce thermally shrinkable and electromagnetic wave proof tube and the product thereof which is internally or externally covered with a metallic net-like sleeve woven by soft zinc coated copper wires so as to make the electric cords arrangement in the tube neat, signal transmissions in a higher quality, appealing to eyes and durable against abrasion in use. The net-like sleeve can be woven by means of a weaving machine with different number of soft zinc-coated wires, such as 16, 24, 32 and 48 wires to obtain net-like sleeves of various densities and sizes. A so woven net-like sleeve is expandedly supported by a hollow metallic rod into shape and it can be adhered to the outer or inner surface of a thermally shrinkable tube. The metallic net-like sleeve can shrink along with the plastic tube when heated. It not only can neatly bind electric cords in a tube but also makes the tube appealing to eyes, durable against abrasion and anti-electromagnetic wave in practical operation.
