Lighting industry lightning protection misunderstanding: LED lighting lightning protection = power lightning protection

I once heard a sentence in a very good Shenzhen company: "Whether wave soldering is relatively simple compared to reflow soldering, our company needs to have full-time expertise to do this, what our company needs. Yes: someone specializes in doing things." I only use this sentence as a starting point, special person to do special things, personal expertise! The same as the company.

In the LED lighting industry, I have published four articles, each of which is half of the explanation for what is reasonable lightning protection technology, and half is why the LED lighting industry is not doing well in the field of outdoor lighting. Today, let's take a look at how the lighting, lights, electrical equipment, platforms and garages of the former Ministry of Railways do "lightning protection".

In view of the fact that the entire LED lighting industry has to deal with lightning protection related matters to the power company, then let's see what happens to the lightning surge.

1 The cause of lightning surge

Just Baidu, everyone will find that the cause of the lightning surge is divided into two parts: external reasons and internal reasons.

External causes: direct lightning strikes or lightning between clouds, extremely unstable changes in electromagnetic fields, etc.;

Internal reasons: operation overvoltage, ground potential counterattack, space electromagnetic coupling and other reasons.

2 lightning strikes

Power line crosstalk, space electromagnetic coupling into sensitive devices, PE potential is too high or unstable, resulting in PE breakdown to N, antenna effect, etc.

3 lightning strikes the energy of the surge

The energy of a single direct lightning strike is about 55 kilojoules of energy, which is 55 degrees of electricity. The problem is that the 55-degree power passes through a fixed physical point in less than a nanosecond. Therefore, we say that the lightning surge is very energetic, but there is a way to solve this problem.

There is a joke in our lightning protection industry: the heroes of Marvel will always absorb the thunder and lightning energy, and then they will become very powerful and powerful. Then the question is coming. How long does it take for the hero of this sad reminder to be filled with the energy of Superman?

4 general solutions for lightning surges

Following the EMC theory, in the lightning protection industry, we also use the same method: partition multi-level protection, the specific method I have already detailed in the previously published article, this "partition multi-level protection" method on Baidu It can also be easily queried.

So, let's take a look at the LED lighting industry. Since my article has been seen by many people, I am saying whether I can participate in the outdoor high-power power solution. Then I can say very responsibly here: Thank you for your trust in me. But I don't think lightning protection is a main function of the power supply. I don't agree that the responsibility of lightning protection needs to be borne by the power company. I don't agree that the system protection project is just something that the power company can afford.

Fingerprint Lock Motor

Fingerprint Lock Motor introduction:

Basic security work, lock body responsible for the security door lock body responsible for opening and closing lock, the lock body Lock Motor is of crucial importance.

Functions: it is widely used in various intelligent locks, such as Shared bicycle lock, fingerprint lock, glass lock, safe lock, hotel lock, family lock, inductive smart lock, etc

Features:Fingerprint Lock Motoris based on micro precision reducer development, small intelligent micro precision reducer can do 10 mm in diameter, is widely used in safe, locks, smart locks, sensor intelligent lock;

This kind of motor has the characteristics of low noise, low energy consumption, small volume, light quality, high precision, large torque and durability

Method of use: the best stable in horizontal plane, installed on the Fingerprint Lock Motoroutput shaft parts, cannot use a hammer to knock, knock prone to press into the dc Fingerprint Lock Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.

Operating temperature range:

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:

Fingerprint 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:

●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.
