The rear end of the reflector is penetrated by a second bolt adapted to the third screw hole.

[0006] Adopting the above technical solution, the lighting component emits light, and the light is reflected by the reflector to achieve directional spotlighting. With the help of components such as the outer protective shell, the battery pack and the circuit board, reliable lighting is provided for the emergency evacuation tunnel to meet the lighting requirements in case of emergency.

[0007] Preferably, the lighting component includes a plurality of LED lamp beads annularly distributed outside the circuit board, and the reflector is sleeved outside the lighting component.

[0008] With the above technical solution, the lighting component is composed of a plurality of LED lamp beads distributed in a ring shape on the outer side of the circuit board. The LED lamp beads emit light when powered on. The reflector is sleeved on the outer side of the lighting component, and the light emitted by the LED lamp beads is converged and directed by using its reflection principle, providing concentrated and bright lighting for tunnel emergency evacuation and guiding personnel to evacuate.
