| LED market analysis data shows, 2011, the global LED market output value reached 16600000000 U.S. dollars, the whole industry scale is still expanding. In the whole system of product, more than 60% production fault as well as more than 70% of the market is due to the failure of repair devices, but most companies are not using the systematic reliability engineering methods to solve, leading to product quality is not high, the service life is not long. China electronic lighting industry by price and other factors, to prolong the service life of the product 's design has obviously insufficient. In view of this, LED Tube can be predicted, in the LED industry development process, how to evaluate and improve LED product service life will become a new topic. Life becomes an important index Using appropriate reliability engineering technology to test, evaluate and improve product reliability, can be improved more than 10 times. LED the use life of the products mainly include the quality and reliability of products and other factors, including product reliability is the influence of the service life of the product key elements. Reliability refers to the products under stipulated conditions and within the stipulated time 's ability to perform its specified functions. The product quality and reliability are among the main causes of low level hardware design, lack of experience, lack of reliability system engineering methods and other factors. Practice has proved that, using appropriate reliability engineering technology to product test, evaluation and improvement, the product reliability is improved by more than 10 times, thereby prolonging the service life of the product. At present, many enterprises in the face of domestic intense competition at the same time, also continue to expand foreign markets, increase to European countries and the United States exports. The European Union and the United States for the LED lighting also published a lot of instruction and standard. For example, the United States Department of energy and the Environmental Protection Agency jointly issued the" Energy Star" law, integral LED bulb life requirement is in use after 25000 hours can be maintained for at least 70% of the initial luminous flux. North American Lighting Association issued LM-80-08 LED product standard, testing method of standardizing, on how to test" rated lumen maintenance of life" to be defined. In Europe, many specialized LED product appraisal standards are being developed, specific standards are as follows: lamps Performance requirements of the standard are IEC 62722-1 and IEC 62722-2-1, LED module performance requirements of the standard is IEC 62717, self-ballasted LED bulb performance requirements of the standard are IEC 62612, LED drive performance requirements of the standard is IEC / EN 62384 of these standards promulgated, LED products will receive a comprehensive assessment. In addition to the current requirements for safety, efficiency, coverage performance requirements, the service life of the product will become the important assessment index. Optimized design effect to get instant results In order to improve the reliability, prolonging the service life of the product, in line with domestic and overseas related standard, the LED product to do some improvements. LED Cabinet/Kitchen light For the enterprises, in order to improve the reliability, prolonging the service life of the product, in line with domestic and overseas related standard, the LED product to do some improvements. For example, to reduce the use of products in temperature, to improve product reliability, prolong the service life of the product, can play the effect to get instant results. In the heat, the traditional way is to add heat sink. But in optimized design of LED product is have the aid of conical shape design. First, because the cone can be formed in a variety of" ventilation", thus helping to transfer the heat radiating effect of bulb, implementation. Secondly, the device reasonable choice, through testing and rejecting unqualified or early failure products also contribute to improve product reliability. In addition, the reasonable process improvement to improve the service life of the product to provide help. In simple terms, is through the standard reasonable process reducing device by the stress, thereby strengthening the performance of products, improve the durability of LED products. In general, improve the reliability of products can effectively improve product quality, and produce more cost-effective, create more economic benefits for the enterprise. At the same time, these products are fair, credible certification will increase the credibility of enterprises, help enterprises more smoothly into the European market.  | |||
