What is the principle of light-emitting gyro?

The light-emitting gyro can emit light when it rotates, which is very popular with children. The light-emitting gyro can emit light because it has a battery and a centrifugal switch. When the gyro rotates, the centrifugal switch is turned on, and the internal flash circuit starts to work, directly driving the LED to emit light. If the light-emitting gyro does not emit light when it rotates, it may be caused by dead battery, poor contact of centrifugal switch or failure of internal circuit board, which can be repaired or returned to the merchant. Let's look at the principle of light-emitting gyro. 1. What is the principle of light-emitting gyro?

Light-emitting gyro is a new type of toy gyro which combines traditional gyro with modern technology. It not only retains the primitive connotation of gyro, but also embodies the attractive charm of modern electronic technology. It glows when it turns, which is very beautiful. So why does the light-emitting gyro shine?

The working principle of light-emitting gyro is to install battery and centrifugal switch inside the light-emitting gyro. When the gyro rotates, the centrifugal switch is turned on. Due to inertia, a lamp needle will touch one end of the battery to conduct light, and the internal flash circuit will start to work, directly driving the light-emitting diodes to flash in turn. The duration and sequence of each LED are irregular and random, so it is very beautiful.

Second, how to repair the broken light-emitting gyro?

When playing with a light-emitting gyro, sometimes the gyro is spinning, but it doesn't light up. So what's wrong with the light-emitting gyro? The reasons why the light-emitting gyro is not bright may be:

1. The battery is dead. Just get a new battery. The location of battery replacement may be different. Just look for it yourself or read the instructions.

2. Poor contact of centrifugal switch contact due to vibration, falling and other problems can be repaired by adjusting contact friction.

3. When rotating, the wire can't touch the battery, and a loop is not formed. Try to fold the wire tighter.

4. There is something wrong with the internal circuit board, which is a product failure. If you don't know the circuit, you can't fix it. Even if you know how to fix it, it will be more troublesome. It is recommended to contact the merchant to return the goods.
