[Text / high-tech LED reporter Luo Shenghua] Heat has always been a big problem that plagues LED. The main thermal conductive materials on the market today include aluminum, plastics and ceramics.
"Aluminum is a metal material, although it is thermally conductive but also conductive. As a material for lamps, it is difficult to pass the safety regulations, and the manufacturing cost is high. The environmental pollution is also large." Dongguan Puwan Optoelectronics Cooling Technology Co., Ltd. (hereinafter referred to as "Puwan Optoelectronics") The project leader Jian Yu told Gao Gong LED reporter.
Founded in 2009, Puwan Optoelectronics is the first company in China to develop and apply thermal plastics to LED bulb lamps. The company has conducted a two-year research and development of materials and products before the product is officially launched into the market.
Jian Yu said that compared with aluminum, the advantages of plastic materials are obvious. The plastic has excellent antistatic properties, high insulation, high plasticity, high thermal conductivity and low pollution performance, and the heat dissipation coefficient is 10 times higher than that of metal copper and aluminum.
In addition, the plastic's directional heat dissipation performance can effectively shield electromagnetic radiation. Moreover, the stability of its own performance, there is no problem of changing the electrical resistivity of the metal for a long time, and there is no problem of acid resistance, alkali resistance, oil resistance, wear resistance and corrosion resistance encountered by the metal radiator in the safety test. LED lighting products.
"At present, there are no more than 10 enterprises producing independent thermal plastic products in China, and the quality level of everyone is uneven." Jian Yu said that Puwan Optoelectronics has excellent antistatic properties, high insulation, high heat dissipation and easy Processing and other properties, insulation up to 5000 volts, can replace traditional aluminum.
At the Hong Kong Autumn Lighting Fair in October this year, more than 30 Puwan Optoelectronics customers brought their lamps using Puwan Optoelectronics' thermal conductive plastics to the overseas market.
At the 2013 Hi-Tech LED Lighting Exhibition, which will be held at the Guangzhou Poly Exhibition Hall on November 25th, Puwan Optoelectronics will bring the company's newly developed high-power LED PAR lights and a variety of stylish bulbs.
Among them, PAR64 (70W) and PAR38 (18W) will be the main products of Puwan Optoelectronics in this exhibition, which has the advantages of beautiful and light, insulation and good heat dissipation effect. At the same time, the use of thermal plastics as the main material of the shell, the light transmittance of the lampshade is as high as 90%, which is the first in the country.
In terms of bulbs, Puwan Optoelectronics has focused on launching several ultra-low-cost explosive products. One of the bulb lamp kits only costs 3.98 yuan, including the lampshade, heat sink, lamp holder and silk, and the color can be selected. In addition, the product adopts single and double vertical fins, and the heat dissipation design is light and insulated, and the effect is good, and the transmittance of the lampshade is as high as 90%.

Led Flood Light is a point can be uniform in all directions of the point light source, its range of illumination can be adjusted. It features with aluminum heatsink , energy saving, water proof, high CRI, environmental and easy install. It is common to use many different colors of floodlights in the scene. These floodlights can be darkly projected and mixed on the model. As the floodlight range is relatively large, the floodlight effect is very easy to predict, and this light there are many auxiliary purposes, for example, the floodlight placed near the surface of the object, it will be in the surface of the object To produce bright light.
