Sichuan Chengdu University students self-made Dengfeng LED lights, won the 2012 London Olympics orders

Chengdu University student Wang Bohao made LED lights and obtained LED invention patents. Recently, his Dengfeng LED lights received orders for the 2012 London Olympics.

Wang Bohao was awarded the invention patent for LED at the age of 18 and founded the company as a university student. In the second half of 2008, a large-scale venue contractor in Lianyungang ordered 100,000 LED lights from him. This business allowed his Dengfeng LED energy-saving lamps to be used in the pavilion of the 2010 Shanghai World Expo.

In early 2009, Wang Bohao participated in the bidding for lighting equipment suppliers in the London Olympics. The samples sent after 15,000 hours and 300 lighting tests, no problem with one of the bulbs, so that the London Olympic Organizing Committee established confidence in his products that "normal work 50,000 hours, light decay is not less than 30%". Recently, the London Olympic Committee issued a formal order to him.

Dc Gear Motor can be defined as an extension of Dc Motor which already had its Insight details demystified here. A dc Gear Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a dc gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.

Features: dc 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:

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:

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 dc gear 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.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●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.
