This case is about a lighting device, especially a handheld lighting device.

In some situations, such as: night ecological tour, overnight camping, night patrol, night fishing small tube or cave mining, etc., the flashlight is used to provide lighting at night or in a dark environment.

Common flashlights use a lens (such as a convex lens or a concave lens, etc.) to allow the light emitted by the light source to be refracted and irradiated to the dark place, so as to achieve the function of clear illumination in a specific direction. However, a lighting device that only has a light source projected in a specific direction is not suitable for a situation where a light source is desired to be visible from multiple angles.

For example, in guiding traffic at night, it is hoped that the light source emitted by the lighting device can be clearly seen from all angles, so as to prevent the user from being unable to play a better warning and guide function and fall into a higher risk.
