As one of the country's five major semiconductor lighting engineering industrialization bases, Shanghai has initially formed a relatively complete LED industry chain, which constitutes a green lighting industry cluster with Zhangjiang Hi-Tech Park as the core and Radiation Jiading, Songjiang and Yangpu. As of the end of last year, Shanghai has 105 LED-related patents, and has established more than 100 national, industry and internal standards for the optical industry.
From the Bund to the Donghai Bridge, a “future light source†called LED is also the “energy pioneer†of the city while playing the night in Shanghai. The reporter learned from the "4th China International Semiconductor Lighting (LED) Forum and Exhibition" that was opened yesterday that by 2010, Shanghai's landscape and public lighting will be sung by LED "Protagonist", when Shencheng is expected to save 1 billion a year. The kilowatt-hour electricity is equivalent to the total amount of electricity used for lighting in a small and medium-sized city.
The LED light is not the "old face" of the filament plus the bulb, but a solid-state light source made of a semiconductor chip. It uses electronic movement to illuminate and directly converts electrical energy into light energy. The conversion efficiency is as high as 68%, which is more than 5 times that of incandescent lamps. Therefore, the power consumption of LEDs is only 1/10 of that of conventional bulbs, and its service life is 100 times. It is estimated that if one-third of the country's traditional lighting is replaced by LEDs, a Three Gorges hydropower station will be saved each year.
The night and the more beautiful night Shanghai and LED can be described as "sentimental." Under the LED embellishment, Shanghai's iconic landscape "Oriental Pearl" consumes only 70 watts per spot, which is nearly 75% less than the original incandescent lamp. Wujiaochang's new landmark "Eggs" is embedded with a strip of LEDs 5 cm wide. It disappears during the day and shines into the night, winning the praise of the public. Incredibly, the 1.42 million light-emitting points distributed on the steel frame of more than 10,000 square meters add up to 80 kilowatts of electricity per hour.
Recently, there are two large-scale events and LEDs. The closing ceremony of the Special Olympics will be supported by LEDs. The outer membrane structure of the 2008 Beijing Olympic Games swimming pool "Water Cube" will be multicolored under the LED background. through. At present, the project is being openly tendered nationwide, and Shencheng enterprises have joined the competition.
Behind the hustle and bustle of the city's night scene is the inexhaustible driving force of technological innovation. As one of the country's five major semiconductor lighting engineering industrialization bases, Shanghai has initially formed a relatively complete LED industry chain, which constitutes a green lighting industry cluster with Zhangjiang Hi-Tech Park as the core and Radiation Jiading, Songjiang and Yangpu. As of the end of last year, Shanghai has 105 LED-related patents, and has established more than 100 national, industry and internal standards for the optical industry.
It is reported that in the next few years, Shanghai enterprises will focus on the key technologies of high-power white LED industrialization, reduce production costs, improve luminous efficiency, and let LEDs truly enter the homes of ordinary people. As one of the 12 strategic products developed by Shanghai's “Eleventh Five-Year†science and technology plan, LED will surely become one of the highlights of the 2010 World Expo.

Features: 12v Dc geared 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.
12V 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.
Method of use: the best stable in horizontal plane, installed on the 12v dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the 12v dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
12v Dc 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:
12v Dc 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 12v Dc geared motor 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
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry. Welcome to our factory.
