The development of the LED lighting industry has achieved excellent results and has attracted great attention from all walks of life. Under the impetus of the ten cities, LED street lights have developed rapidly. According to the statistics of high-tech LEDs, a total of 222,000 LED street lights were installed nationwide in 2009. In 2010, the work of the ten cities and towns entered an important implementation stage. Local governments outside the 21 pilot cities are still actively applying for joining, and the first pilot has become a flowering place. In 2009, LED street lights were over-hyped and over-invested, and they have become high-risk industries. It is understood that most of the LED street light companies in 2009 were losing money. This was caused by blindly following the trend, and secondly because the cost of street lamps was too high. The quality of the products is mixed, the light-off rate after installation is too high, and the subsequent maintenance costs make the company profitable or even lose money.
Nowadays, the most popular mode of LED street lamp enterprises is contract energy management. In the renovation of LED street lamps, several cities have begun to adopt them. Among them, the first phase of the 5000-inch LED streetlight renovation in Chancheng will be introduced into the EMC model for the first time. By the end of 2009, Chancheng adopts users. + Enterprise + bank contract energy management mode installed a total of 11,000 LED street lights, Deqing County introduced a new contract energy management model in the LED street lamp energy-saving transformation, Guangzhou City also decided to adopt EMC mode, with 23 years, about 18 in the city Wanhao LED street lamps are energy-saving retrofits, and it is foreseeable that they will generate huge economic and social benefits. However, EMC requires streetlight companies to pay for the entire project cost, and to pay for the construction cost with the later savings of electricity, the length of the cycle varies, the short-term is 3 years, and some can be more than 10 years. This directly tests the company's funds and brings a lot of risks.
Opportunities often coexist with risks. On March 19th, at the 5th LED Industry Theme Summit Forum jointly hosted by Gaogong LED and Tianjin Dongli District Government, Sunshine Optoelectronics Sun Jianhua gave a wonderful speech on EMC's opportunities and risks.
Sun Jianhua pointed out that EMC has a huge opportunity to promote in China: LED is a strategic emerging industry with huge potential. The government will mainly explore EMC and make private capital have the opportunity to make profits. Secondly, the EMC model can break through the LED street lamp demonstration project. The risk bottleneck of high risk guarantees the maximization of benefits, risk and minimization of production, consumption and finance; EMC customers do not need to bear the funds, technology and risks of energy conservation implementation, and the new model of domestic and foreign fund EMC profit; China The LED market is getting hotter and hotter, and energy-saving products are being marketed.
At the same time, Deshida Sun Jianhua also stressed that EMC risk can not be ignored: the imperfections and lack of LED street lamp standards and application standards, as well as the problems in the current application, can not ignore the avoidance; at the same time, EMC is not a perfect model, and needs further exploration. Perfect; the most important thing is that the quality and reliability of LED street light products directly determine success or failure.
LED street light companies believe that their products can be, traditional lighting believes that there is a certain gap, the complaints of ordinary people, the dilemma of government departments and the bottleneck of local protection, and the introduction of contract energy management mode has brought troubles and confusion to some LED street lighting companies. . Recently, a new version of contract energy management users + banks + companies has emerged. Although the new version reduces the risk of the enterprise, it is not a relatively complete model, and the relationship between the company and the parties needs to be further explored.
LED road lighting has been hailed by the industry as a lonely long-distance running, and some people have dubbed it as a delicious chicken rib. Faced with the opportunities and risks in front of you, Gaogong LED recommends that LED streetlight companies should pay attention to assist in researching the operation mode. Want to clearly understand the large-scale sale of LED street lights to the government, is it realistic? How much do companies know about EMC's operating model, funding sources, etc. Who will act as an EMC organization? EMC institutions are willing to act as a wishful thinking? EMC institutions and enterprises What is the relationship? How many years is it right to operate? Don’t blindly follow the wind before seeing the immediate interests, and finally lose more than gain.
China's EMC is currently facing a good development opportunity, but due to the technology of LED street lamps, product reliability, localized business models, especially financing models, and the corresponding policies of the government from the introduction to the improvement, there is still a process of gradual development. Gaogong LED believes that we can temporarily hope that the energy-saving service companies affiliated with the utility companies will appear and develop as soon as possible.
Dc Gear Motor, namely Gear Reduction Motor, is based on ordinary Dc Motor , coupled with gear reduction gearbox.
The gear reducer is used to provide low speed and large torque.
At the same time, the gearbox with different deceleration ratio can provide different speed and torque.
Generally different industries, using different power dc motor, generally adopt custom parameter design pattern.
What are the four ratings of the Dc Gear Motor? The DC gear motor is often seen in our industrial production. Here Shunchang Motor gives you the knowledge of its four ratings. To talk about
1. Rated Current: The rated current is the maximum current allowed to flow through the armature winding of the DC deceleration motor in accordance with the specified operating mode, in A.
2. Rated Voltage: The rated voltage is the maximum additional voltage that the armature winding of the motor can work safely, unit V. It
3. Rated Speed: Rated speed refers to the rotational speed of the Gear Reducer Motor in the rated voltage, rated current and output rated power under the circumstances of operation, the unit is r/min. Such
4, rated power: rated power refers to the motor in accordance with the specified mode of operation can provide output power. For motor, rated power is the output of mechanical power on the shaft.

Features: gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
