Description

Technical Field

[0001] This utility model relates to the field of explosion-proof sign light technology, and in particular to a fire emergency light fixture with centralized power collection and control. Background Technology

[0002] In numerous locations and complex environments, sign lights play a vital role, providing crucial guidance functions such as road signage, emergency evacuation during power outages, and directional lighting. Common examples include safety exit signs, fire safety signs, school bus signs, tunnel signs, and traffic lights. Explosion-proof sign lights are widely used in hazardous environments or locations such as oil extraction, chemical industry, military industry, and ships, undertaking the tasks of indicating safety exits and guiding safe evacuation during power outages. They need to possess certain explosion-proof properties to meet the requirements for use in hazardous environments.

[0003] However, traditional lighting equipment is significantly inadequate in addressing the safety needs of special environments, often neglecting safety requirements in these conditions, making it prone to malfunctions, and potentially even causing safety accidents. With the continuous advancement of intelligent technology, market demand for lighting equipment has expanded beyond basic lighting functions; people expect lighting equipment to possess intelligent control and emergency alarm capabilities to better handle various situations.

[0004] Currently, although explosion-proof lighting fixtures can provide a certain level of safety, many problems still need to be addressed. Structurally, many explosion-proof lighting fixtures are overly complex, making installation and maintenance difficult, thus increasing operating and time costs. Regarding lighting efficiency, the focusing design of some explosion-proof lighting fixtures is inadequate, leading to diffused light, which not only affects the lighting effect and reduces lighting quality but also wastes energy. In terms of intelligent control, most traditional explosion-proof lighting fixtures lack intelligent control systems and cannot automatically adjust brightness or issue alarm signals according to changes in the surrounding environment, significantly reducing their responsiveness in emergencies. Furthermore, existing explosion-proof lighting fixtures are often designed for specific environments, lacking flexibility and adaptability, making it difficult to meet the diverse lighting needs of different occasions and limiting their widespread application and promotion.
