What protective capabilities should the road lighting have?

LED lighting technology has developed to the present day, the overall performance of LED optical modules has been quite stable, the key to directly affect the life of lighting is the reliability of power supply drive. There are data indicating that more than 70% of LED outdoor lighting faults are caused by power failure or instability. cause. At the same time, outdoor lighting is also the focus of many LED lighting companies in the field of competition and competition, but the outdoor lighting application environment due to thunderstorms, summer high temperatures, winter cold and other natural phenomena are inevitable, more complex than the indoor environment, so the power supply The reliability requirements of the drive are also more stringent. What kind of protection can the outdoor lighting products have for the outdoor environment that is more harsh than the indoor environment?

Zhongheng Paiwei Power Supply, invested by Hangzhou Zhongheng Electric Co., Ltd. (stock code: 002364), the largest communication power supply manufacturer in China, has more than 20 years of experience in power supply manufacturing, and has more protection and design for outdoor power supply. Leading, the reporter learned that a good outdoor lighting driver power supply should have the following protection capabilities:

1. 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 .

2, resistance to 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.

3, 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, short-circuit protection, and even over-power protection of the power supply are also essential.

Door Lock Motor

Door Lock Motor Characteristics 1. No direction: don't need to distinguish the door direction, left and right sides, both inside and outside the door, can be universal. (convenient purchase locks and reduce inventory).

Door Lock Motor Dc Gear Motor

2. Power: the power consumption is only equivalent to one 5 of the electric control lock, electric lock, 3 A magnetic lock power to open the door, often consumes 0.27 A. And spiritual lock unlock instantaneous current is less than 0.5 A, reduced the entrance guard, talkback host power consumption.

3. No collision: close the door without collision, reduces the choice of door closers requirements (not necessarily with 65 kg of door closers, door closers are free to choose to suit the door), to solve the building door because the door closers clash of the hydrodynamic force is too high, it is not easy to make the door more deformation, prolong the service life of the body.

4. The voice is light: close the door automatically locked, no noise, solves the noise due to electric control lock itself.

5. Life is long, life is up to 350000 times


Operating temperature range:

Mini Door Lock Motor 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 lock 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:

lock motor 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 Door Lock 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.


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.
