The embodiment of the invention provides an early warning lighting device and an early warning lighting device group, collapse early warning can be carried out on rock mass in real time, the early warning lighting device comprises at least one early warning group and a visible light conversion part, the at least one early warning group comprises at least one early warning subgroup, the at least one early warning subgroup comprises a base, and the visible light conversion part is arranged on the base. The at least one pressure-sensitive semiconductor light-emitting device is arranged on the substrate, the pressure-sensitive semiconductor light-emitting device is used for changing the color of emitted light when sensing the pressure change, and the visible light conversion part is used for converting the light emitted by the pressure-sensitive semiconductor light-emitting device into visible light. According to the early warning lighting device, tunnel or mine collapse can be monitored in real time, and after the early warning lighting device is driven into the rock mass, when the stress of the rock mass changes, the early warning lighting device changes the light emitting color to achieve real-time early warning.
Description
technical field [0001] The embodiments of the present disclosure relate to, but are not limited to, an early warning technology, and more particularly, to an early warning lighting device and an early warning lighting device group. Background technique [0002] At present, the real-time early warning of tunnel and mine collapse has always been a big problem. The mining industry of our country and even the world will cause heavy casualties and economic losses due to landslides every year. However, due to the extremely sudden and unpredictable nature of landslides, it is currently impossible to provide real-time warnings for landslides. SUMMARY OF THE INVENTION [0003] The following is an overview of the topics detailed in this article. This summary is not intended to limit the scope of protection of the claims. [0004] The embodiments of the present disclosure provide an early warning lighting device and an early warning lighting device group, which can perform cave-in...
