The power interface 102 is used for connecting an external power supply, the external power supply provides voltage and current for the whole lamp system, and the power interface 102 is connected with the first wiring terminal 103 through wiring inside the circuit board. The LED interface 101 is used for connecting an LED lamp, and the LED interface 101 is connected with the second wiring terminal 104 through the internal wiring of the circuit board. The LED interface 101 and the power interface 102 are both high-frequency and fragile elements, and are uniformly arranged on the first circuit board 10, so that the LED driving module 201 is convenient to maintain and replace, and the fragile LED driving module 201 is arranged on the second circuit board 20, so that the second circuit board 20 does not need to be detached when the elements on the first circuit board 10 are overhauled.
The second circuit board 20 includes an LED driving module 201, a third connection terminal 202, and a fourth connection terminal 203. The LED driving module 201 has a function of driving the LED lamp to turn on or off, in this embodiment, the LED driving module 201 is connected to the third connection terminal 202 and the fourth connection terminal 203 through the internal wiring of the circuit board, the third connection terminal 202 is connected to the first connection terminal 103, and the fourth connection terminal 203 is connected to the second connection terminal 104. Because the first connection terminal 103 is connected to the power interface 102, and the third connection terminal 202 is connected to the LED driving module 201, the connection between the power supply and the LED driving module 201 is realized by the connection between the first connection terminal 103 and the third connection terminal 202, so that the LED driving module 201 is supplied with power by the power supply. In addition, the LED driving module 201 is further connected to the fourth connection terminal 203, the fourth connection terminal 203 is connected to the second connection terminal 104, and the second connection terminal 104 is connected to the LED interface 101, that is, the connection between the LED driving module 201 and the LED lamp is realized through the connection between the second connection terminal 104 and the fourth connection terminal 203, and the LED driving module 201 can drive the LED lamp to light or extinguish.
The overall working principle of the replaceable lamp system provided by the embodiment is as follows: the power is connected to the power interface 102, the current is conducted to the third connection terminal 202 on the second circuit board 20 through the first connection terminal 103 on the first circuit board 10 and then conducted to the LED driving module 201, the LED driving module 201 is conducted to the second connection terminal 104 on the first circuit board 10 through the fourth connection terminal 203 and then conducted to the LED interface 101 on the first circuit board 10, and the LED lamp is connected to the LED interface 101, so that the LED lamp can be driven to light and extinguish.

When the worker needs to repair the first circuit board 10, the worker only needs to remove the first circuit board from the second circuit board 20, and the repair is simple and quick.
The replaceable lamp system adopts a double-layer circuit board structure, so that the occupied area is greatly reduced and the whole volume is smaller compared with the traditional single-layer circuit board structure. Because the LED interface 101 and the power interface 102 which are high in use frequency, frequently inserted and pulled out and easy to fail are arranged on the first circuit board 10, when the lamp is checked for faults or maintained, only the first circuit board 10 needs to be pulled out of the second circuit board 20, the second circuit board 20 does not need to be removed, the checking and maintaining efficiency is improved, and the influence of frequently removing the second circuit board 20 on the performance of the second circuit board 20 is avoided. In addition, because the first circuit board 10 and the second circuit board 20 are separately arranged, once the first circuit board 10 fails, the elements of the second circuit board 20 are not affected, and only the first circuit board 10 needs to be replaced, so that the maintenance cost is reduced, and the service life of the elements on the second circuit board 20 is prolonged.

That is, the voltage on the first circuit board 10 is stepped down and stabilized and then provided to the LED driving module 201, so as to provide a safe voltage for the LED driving module 201.
The voltage reduction and stabilization module 204 is disposed on the second circuit board 20 because of its stable performance, less damage and low maintenance frequency.
