Energy-saving high-supportability LED long-afterglow device luminescent system and regulation and control method thereof

Abstract

The invention provides an energy-saving high-supportability LED long-afterglow device luminescent system, comprising a direct power supply (1), an energy storage power supply (2), a switching power supply controller (3), a driving control circuit (4), a control module (5), an LED long-afterglow luminescent device (6) and a charge-discharge control circuit (7) which are connected together through circuits according to needs. The system not only has a luminescent function of a conventional LED but also has a luminescent function of a long-afterglow material. An aim of saving energy is achieved by virtue of intermittent power supply for the LED long-afterglow luminescent device (6); and by performing grading detection on the capacity of the energy storage power supply (2) and adopting a corresponding period and duty ratio or power to supply power to the LED long-afterglow luminescent device (6), the luminescent time delay of the luminescent system and the afterglow brightness of the long-afterglow material are improved to the utmost extent, so that the luminescent supportability can be improved, and specifically, the luminescent system has unique advantages especially in military application.

Description

[0001] Technical field: [0002] The invention relates to the technical field of special lighting, in particular to an energy-saving and high-guarantee LED long-afterglow device lighting system and a control method thereof. [0003] technical background: [0004] With the needs of China's economic growth and social development, the country pays more and more attention to and continuously strengthens the investment and construction of public and national defense undertakings, including high-speed rail, aircraft, surface ships, submarines and other equipment. The number of public facilities such as tunnels and culverts, high-speed rail stations, airports, military bases, emergency shelters, and underground civil air defense projects is increasing, and their volume is also increasing. In these equipment or places, in consideration of safety and security, in addition to conventional means, the lighting in between must meet the rigid requirements of uninterrupted lighting and the ri...

AI Technical Summary

Problems solved by technology

[0006] 1) Due to the aging or damage of the energy storage power supply, or sometimes the energy storage power supply is not enough, it is often impossible to ensure the normal operation of the emergency lighting system

[0007] 2) Partial damage to the above-mentioned equipment or places, such as fire, flood, war damage, etc. will easily lead to paralysis of the lighting system

[0008] 3) As the lighting fixtures are turned on all night and accumulated over time, not only a huge amount of energy is consumed, but also due to the high working temperature caused by long-term operation, the actual service life of the lighting fixtures is much less than the expected life

Traditional military lighting equipment simply relies on electricity to emit light, but it is still fully exposed in front of the enemy's infrared thermal imager, and can only be reduced to the enemy's target
