It is altered in LED chip and is connected to constant-current control circuit, the constant-current control circuit can be such that the electric current for flowing through LED chip stabilization is providing
Value, it is ensured that the service life of LED is unaffected.
Further, the monitor and AC voltage regulator, charger, battery, switching switch connection.
Further, the monitor is used to monitor each seed ginseng of AC voltage regulator, charger, battery, switching switch
Number, the monitor can AC voltage regulator, charger, storages to continuous illumination device by communication interface, control centre
Battery, switching switch implement long-range monitoring, to ensure illuminator reliably working.
Further, the battery is equipped with two groups, and one group primary, and another group spare, passes through between two group storage batteries
Automatically switch or the mode of manual switching is replaced.
Compared with prior art, the invention has the benefit that
1, present invention employs the AC led light technologies quickly grown in recent years；AC LED light does not need supply convertor, not only
The volume and weight for reducing LED, improves application space, saves the cost of transformation exchanger package, and the also LED of saving over exists
15~30% power loss, improves the luminous efficiency of integral LED when converting between direct current, alternating current；AC LED light is also
With can both work in AC input, it can also work the characteristics of DC is inputted, have very for simplifying power supply system structure
Important meaning；AC LED light is than incandescent lamp economize on electricity 90%, than the strong light of common fluorescent lamp and high-pressure sodium lamp under Same Efficieney
Spend high by 40% or more, and the service life, up to 100,000 hours, colour rendering index is up to 80 or more, significantly larger than high-pressure sodium lamp.
2, AC LED light of the invention in LED chip by sealing in constant-current control circuit, even if due to external alternating current
Source voltage increases or LED chip forward voltage drop reduces, and the electric current for flowing through LED chip can also be stablized in specified value, it is ensured that the longevity of LED
It orders unaffected, so that AC LED light be allow to work under DC input voitage, therefore is saved in Emergency Lighting Supply system
Expensive high-power inverter has been removed, and has reduced linear transformation, system effectiveness and reliability is made to be greatly improved
While the initial investment of continuous illumination system is also greatly saved.
