Ningbo Jingcheng Technology Co., Ltd. is a professional IC Card Heat Meters manufacturer.
Jingcheng Heat Meters are measuring devices for a precise consumption metering. For measuring the heat which, in a heat-exchange circuit, is absorbed or given up by water called the heat-conveying liquid.From the start, we have developed innovative products based on the technology in dialogue with our customers. The result is a collection of well-engineered measuring instruments proved time and again in practice, because exact consumption values are only possible with precise measuring technology.
Please feel free to contact us if you need any IC Card Heat Meters.

Polaris Power Network News: While the industry is developing rapidly, the market is also expanding rapidly. On the one hand, traditional power supply manufacturers have launched LED power products, on the other hand, many entrepreneurial companies have also been established. However, the power supply technology is not yet mature, the relevant standards have not been introduced, and the market is chaotic. Relevant experts believe that the market will eventually lead to a situation dominated by a few giants, marketing strategy and product quality are the key to success. Market expansion, price wars started in 2010, the industry is mixed, the market is expanding rapidly, but not all participants have made money. Most of the street lights did not make money, and the led tunnel lights earned some living expenses. The enterprises that do commercial lighting have strong foreign trade ability, and chip companies have made money. Many domestic chip companies have been in a loss state before, and there was a turnaround in 2010. Packaging companies make money because they are not married in 2010. It is worth noting that most LED power companies are also making money, but there is no shortage of goods like this, because LED power is technically a traditional electronics industry, and China's electronics industry already has strong manufacturing capabilities. However, the industry has not risen for a long time, and the price war has started, especially in the field of low-power power supplies. It is understood that the price of low-power LED power supply has been very transparent, such as the price of power supply is generally around twenty-four. However, the power supply is still at a high profit margin. One of the reasons is that the technical threshold is relatively high and the capital investment is large. Another reason is that high-power LED power supplies are mainly used in street lights and tunnel lights. Currently, these lamps are mainly used for government demonstration projects. In order to demonstrate good results, the street lamp manufacturers used the best accessories (at least on the sample lamp), which caused the manufacturers to put forward higher requirements for the power plant and increased profits. In order to demonstrate good results, street lamp manufacturers have adopted the best accessories (at least on the sample lamp), resulting in high profits of high-power power. The survey found that the business of LED power plants such as Mingwei, Infineon and Moso has increased several times in 2010. Power technology is not yet mature It is understood that the quality of LED power supply for indoor lighting is very unstable. One or two of the ten will flash after a period of time. Huagui Chao, chairman of Infineon, believes that some small factories now only consider that they can work when designing power supplies. They do not consider the working environment and sometimes need to work in harsh environments. North Huihua Xu Changchun believes that: the threshold of LED power supply is not high, but it is not easy to do well, to do research and development, good materials and good production, sometimes the sample is no problem, but the volume may appear after the bulk problem. Some components in Guangdong are quoted in pounds, and we use the price quoted. He added. Although most of the faults occur on the power supply, they cannot blame the power supply company. LED street light expert Xu Liancheng told reporters that power failure is the result of a multi-factorial combination of effects, many of which are caused by unreasonable design of lighting companies. In order to effectively reduce the power failure, it is also necessary for power companies and lighting companies to strengthen interaction and work together. According to incomplete statistics, the faults generated by LED lighting products today are from the power supply. From the past few years, the product packaging technology has been continuously improved and the heat dissipation technology has been continuously developed. The stability of the light source has reached a relatively good level, even if there is that Light decay and color drift, which is mainly caused by the unreasonable heat dissipation design. The situation of direct necrosis is very small. Relatively speaking, the problem of power supply is much more serious. When a problem occurs, it is usually a direct death or flashing, and the frequency of occurrence is relatively high. Of course, there are still many shortcomings, such as the lack of standards, which leads to increased maintenance costs for manufacturers, which is not conducive to the development of the LED industry.
