The outdoor lighting application environment has natural phenomena such as thunderstorm climate, summer high temperature, and winter low temperature, and is inevitable. Compared with the indoor environment, the reliability requirements for power supply drive are more strict. LED lighting technology has developed to today, LED light The overall performance of the module has been quite stable. The key to directly affecting the service life of the LED is the reliability of the power supply. There are data indicating that more than 70% of the LED outdoor lighting faults are caused by power failure or instability.
For outdoor lighting application companies, the quality of power supply on the market is uneven and the price is very different. How to identify the quality of power supply is not easy. In fact, at present, the unilateral price of power supply is no longer the decisive factor for users to choose the power supply. The maintenance cost of outdoor lighting will directly affect the profit margin of lighting projects. Users will also consider the quality and performance of power supply. Reliability, the company's comprehensive service capabilities and other factors.
To this end, in the four-day Guangzhou International Lighting Exhibition last month (June 9-12), Zhongheng Powerway (powered by Hangzhou Zhongheng Electric Co., Ltd., the largest domestic communication power manufacturer), stocks Code: 002364), with more than 20 years of experience in power supply manufacturing, has extensively communicated with customers on how to make a good power supply. From research and development design, process engineering, material selection and warehousing, to refined production, quality control and many other aspects, it is a systematic project to read out the power supply to the lighting customer in detail. This requires both research and development of many years of technical experience and fine manufacturing. System support, the purpose is to help lighting customers have a clear screening for high quality and good power when selecting power.
Good power supply should have a sound ability <br> <br> lightning protection capability. As we all know, the outdoor lightning strike climate is very harmful to the power supply. There are usually several types of direct lightning, conductive lightning, and induced lightning. Inductive lightning is the most common, and the power supply is also the most damaged, often producing 4KV or higher. Good power supply should have better lightning protection capability, and follow the relevant national design standards (GB/T 17626.5, which is equivalent to IEC-61000-4-5, specifies differential mode compression 2KV, common mode compression 4KV). Based on the climate characteristics of lightning strikes, the lightning protection design of Zhongheng Paiwei power supply is usually higher than the national standards. The differential mode compression is 4KV and the common mode compression is 6KV. Of course, in addition to the integrated power supply lightning protection design, some special lightning strike dense areas, lighting users can also refer to IEC61643-1 or EN61643-11 and other related standards, add independent lightning arrester at the front end of the lighting transmission, the effect will be better .
High temperature and cold resistance. In some areas, the outside temperature can be as high as 50 ° C, and the lowest is often as low as minus 30 ° C, which requires the power supply must have a wide range of working ring temperature, Zhongheng dispatch power supply through careful selection and excellent heat dissipation design, at -40 A wide range of work from °C to +70 °C ensures reliable and stable performance.
Waterproof ability. Although the power supply of the market is rainproof and waterproof, the protection capability is very different. The protection level of rain protection only requires IP65, while the protection level of waterproof requires IP67, which means it can be safely used even if the power supply is immersed in water. It can avoid the influence of humid moisture, salt spray, etc. on the internal PCB circuit and components of the power supply. Zhongheng Paiwei Power Supply adopts potting technology and fully achieves IP67 protection level to prevent power failure caused by moisture or salt spray breathing effect. At the same time, the heat conduction performance of special potting material is also very good, which can help power supply heat dissipation and potting process. Although the cost is increased, the use of the product is reliable, and the quality hazard can be eliminated.
In addition, over-temperature protection, over-voltage protection, under-voltage protection, and short-circuit protection of the power supply are also essential.
Good power supply should have the power to support sophisticated manufacturing system <br> <br> appearing on the market, recall, or batch quality problems, for reasons of design defects are in the minority, mostly due to business reasons or manufacturing system is not perfect, the production Inadequate management experience. Fine manufacturing systems generally include six major control platforms, including technology research and development, process engineering, procurement control system, storage system, automatic flow production, and quality control. Often the most prone to problems are procurement, process engineering and quality control.
There are nearly 200 BOM raw materials for outdoor power products. There are a lot of fake materials, defective materials and expired materials on the market. It is often impossible to distinguish in mass production. As long as one device is unstable, it will cause the risk of power failure. How to ensure the quality of raw material procurement Integrity, not only the scientific control of the procurement platform, but also the accumulation of long-term experience with suppliers. In the past 20 years, Zhongheng Paiwei has accumulated a large number of high-quality raw materials for raw materials, and has formed a complete system. The main components are all international first-line brands, such as: INFINEON (Infineon), ST (Italian Semiconductor), ON (Anson ), NCC (Black King Kong), etc., high-quality supply resources will ensure that in the early stages of production introduction, directly eliminate the mixing of fake materials, defective materials, expired materials, to prevent in advance. In addition, the storage of certain components can not be ignored, improper storage environment can easily lead to oxidative deterioration of components, Zhongheng Paiwei specializes in a constant temperature and humidity warehouse to prevent device deterioration.
The product is indispensable in the process engineering process before batch conversion. Its function is to verify the prenatal technology of the product through trial production, and to develop a rigorous product production process through trial production to ensure the effectiveness and accuracy of subsequent mass production. Sex. Process engineering needs to be equipped with corresponding testing equipment. Many power companies often save this cost in order to save costs, which will bury hidden dangers in the quality of subsequent mass production. Each of the power supplies of Zhongheng Paiwei must be technically verified in accordance with the regulations for the various indicators and performance of the R&D design before the mass production. At the same time, the rigorous production operation process is formulated.
Quality control is the core control link of product quality assurance. Generally, power supply companies will have quality control, but the quality control system is sound but different. Zhongheng Paiwei has always checked (IQC) and online inspection (IPQC, LQC). To the factory inspection (OQC) a total of more than a dozen processes, has a professional quality and high quality management team, with reference to the latest international inspection standards, established a set of high standard quality control system, product quality has data traceability.
