(1) Embedded light bar can not be installed directly on combustible objects Some families use three plywood lined with paint behind the ceiling lamp for aesthetic purposes, which is actually very dangerous and must be insulated; if the high-temperature parts of the lamp surface are close to combustible objects, insulation or heat dissipation measures should also be taken.

Isolation power supply/communication module

Papua New Guinea Isolation power supply/communication module

The power isolation circuit, including a protection capacitor, a DC to DC power supply chip, a freewheeling circuit, a first resistor, a second resistor and a DC power isolation module, the protection capacitor is connected in parallel between the positive and negative poles of the input end of the DC to DC power supply chip, a series freewheeling circuit is connected between the drive end and the switch end of the DC to DC power supply chip, the output termination of the freewheeling circuit is connected to the first end of the first resistor, and the second end of the first resistance is grounded by the second resistor, The voltage feedback terminal of the DC to DC power supply chip is connected to the connection of the first resistance and the second resistance, the positive terminal of the input end of the DC power isolation module is connected to the first end of the first resistor, the negative terminal of the input end of the DC power isolation module is grounded, and the output end of the DC power isolation module provides an output voltage. It can play an isolation role and eliminate potential safety hazards.
