At least one light source module 40 is connected to the power converter 20, and the power converter 20 is connected to the external power supply V-bat. The power converter 20 is powered by the external power supply V-bat and generates a driving current based on the corresponding pulse width modulation control signal to light up the light source module 40 connected thereto. That is, the switch module 30 only needs to control whether the pulse width modulation control signal is transmitted to the corresponding power converter 20, and the switch module 30 is not responsible for the distribution and management of the power supply.

Furthermore, the peripheral circuits of the microcontroller MCU (including the switch module 30) are relatively simple, and the workload and heat generation of the microcontroller MCU are relatively low, so there is no need to set a heat sink on the first circuit board 51, which effectively reduces the cost. In addition, the light source module 40 and the power converter 20 connected thereto are integrated on the second circuit board 52. Since a heat sink is provided in the light source module 40, the power converter 20 can reuse the heat sink for heat dissipation, thereby further reducing the cost.
