Abstract: A flame-proof portable power supply includes a battery pack, an electrical assembly, a metal housing and an aerosol fire extinguishing device. A holding cavity for installing the battery pack or the electrical assembly are formed in the metal housing, the battery pack is electrically connected to the electrical assembly, and the battery pack is directly connected to the metal housing. The aerosol fire extinguishing device is disposed in a holding cavity, and the aerosol fire extinguishing device is configured to release aerosol in the holding cavity when temperature in the holding cavity reaches a specified temperature value.

Abstract: A flame retardant lamp includes a lamp body, a printed circuit board (PCB), a power supply, a light-emitting plate, a controller, a driving circuit, and a first temperature sensor. The PCB, the power supply, and the light-emitting plate are disposed inside the lamp body, the controller and the driving circuit are disposed on the PCB, and the first temperature sensor is disposed on the light-emitting plate. The controller is electrically connected to the light-emitting plate through the driving circuit, the first temperature sensor is electrically connected to an input end of the controller, and the power supply is electrically connected to a power supply end of the PCB.
