Technical Field

The present invention generally relates to a light fixture for indicating.

Background

With the continuous acceleration of the urbanization process in China, large public buildings are continuously increased, and building places such as enterprise and public institution office buildings, high-rise residential buildings, commercial buildings, science and education and literature buildings, communication buildings, transportation buildings and the like become very important parts in the culture and economic life of the masses of people. The building structure of the large public building has the characteristics of high space, large span, large area and the like, wherein the building structure comprises underground buildings, doors and windows which are directly opened outwards are not arranged in the places generally, the sealing performance is stronger, and the fire accidents are easy to occur due to the concentrated articles, more combustible materials and larger fire load in the places. People in large public buildings are highly gathered, the crowd characteristic difference is large, the mobility is large, the building structure is often not known enough, and once a fire accident happens in the large public buildings, people are easy to panic.

At present, most of large public buildings adopt a traditional evacuation indicating system, the evacuation indicating direction of the traditional evacuation indicating system is fixed, the principle of 'nearby guiding' is adopted, the actual development of accidents such as fire disasters and emergencies cannot be combined to dynamically change and guide people to evacuate in real time, and people who are originally in a safe area are easily introduced into a dangerous area.

The fire sign evacuation indicating lamp is used for facilitating escape of evacuees from a fire area safely and accurately when a fire occurs. The induction of people to take reasonable and correct actions when an accident occurs can more effectively help people to timely identify evacuation positions and directions under the condition of dense smoke and smoothly evacuate quickly along the indication of the fire-fighting signboard.

The icons, the light sources and the like of the traditional emergency fire-fighting indicating lamp are fixed when leaving a factory, the functions of the traditional emergency fire-fighting indicating lamp are correspondingly fixed, the light sources are unique, and the traditional emergency fire-fighting indicating lamp is basically installed and applied in a distributed mode by using independent products without a wireless communication mode. The flexible application of real-time dynamic fire emergency indication can not be obtained according to the requirements of users, and the light warning and light indication of fire emergency sign patterns can not be adjusted according to actual scenes and requirements. The difficulty of the single indicating lamp in the building in fault elimination and routine maintenance and overhaul is also increased.
