The 50-year secret history of LED technology has gone from zero to the whole world

Foreign media reported that when he showed his inventions to GE executives more than 50 years ago, Nick Holonyak, the inventor of LEDs (Light Emitting Diodes), firmly believed that LEDs would replace incandescent bulbs. Although incandescent bulbs are still the mainstream product in home lighting, LED has changed lighting applications in many ways. LEDs have been accepted all over the world, from switch indicators that emit faint red light to high-brightness street lamps used in the streets of major cities.

Red LED everywhere

The first LED light is red. This is not out of aesthetic considerations. LEDs are made by building multiple semiconductor wafers on silicon wafers. As more and more semiconductor wafer layers are added, people begin to use various additives to determine the color of LED lights. Immerse the thin silicon wafer in the molten liquid, and then add metal contacts and wires. The gallium phosphide arsenide solution used in the first LED lamp will produce a natural red light. Therefore, the default color of the LED light used as an indicator light is red.

The LED lamp made by the new process can also emit light of other colors, thereby greatly expanding the application range of the LED lamp. But in the first 10 years after the advent of LED lamps, the light emitted by such lamps has been red.

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.

Lock motor

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:

The longevity of Fingerprint 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
