Powered by control circuit (9) to LED illuminator by some cycles interval and (or, give LED by control circuit (9)
Illuminator is powered by some cycles interval and carries out periodicity power supply and SECO to LED illuminator).As Fig. 2 and Fig. 3 is set
A length of T1 (powered-on mode) during LED electrified light emittings within each cycle, in the case of system hardware condition is fixed, T1 is necessary
The time needed for saturation is excited more than or equal to long-afterglow material (i.e. long-persistence luminous layer).Now corresponding luminescence unit luminance
It is to be formed by stacking by LED is luminous with long-persistence luminous brightness to spend for maximum luminousing brightness value B1, the brightness value.We can basis
Need to select the LED luminescence units of different size power to determine maximum luminousing brightness value B1.LED stops a length of during electrified light emitting
T2 (power-down mode), T2 refer to that long-afterglow material stops being energized into brightness decay to minimum brightness value B2's after being excited by saturation
Time.This period remains luminous by long-persistence luminous layer twilight sunset itself, in next cycle LED energization eves, it is long more than
The luminosity of brightness illuminator is minimum brightness value B2, and setting minimum brightness value B2 is more than or equal to long afterglow LED luminescent systems
The minimum brightness value of required maintenance, the stopping of long afterglow LED luminescent systems are energized to its luminosity and decay to minimum brightness value B2
Time be die-away time (or power-off time) T2, so move in circles.Based on principles above, we can be in certain limit
It is interior to be needed according to actual conditions to control the minimum brightness value B2 of LED component.
LED conduction times are T1, and power-off time T2, T1+T2=T are a cycle, so circulation, therefore the present invention is long
The electric energy of twilight sunset LED component is T2/T.T2 is power-off time in a cycle, and T1/T is dutycycle, by the length for adjusting T
It is short to determine to distribute relatively strong light and dim light time interval and electric energy with dutycycle.Therefore, meet in minimum brightness value B2
On the premise of it is required that, we can improve electric energy by adjusting dutycycle.There is energy-conservation to imitate based on this principle present invention
Fruit, the also miniaturization for supporting power-supply system provide premise.
Such as Fig. 4, long afterglow LED component (10) can select to be grouped on demand, and group number is not less than 2, per group selection one or one
Individual above luminescence unit.Every group is powered according to certain sequential, and every group of power-on time staggers, thus whole LED
Device instantaneous power consumption just have dropped.The largest packet number that LED is grouped sequence circuit in theory is (1+T2/T1) and round numbers, when
Sequence power supply group number is more, then whole LED component instantaneous power consumption accounts for the ratio of total rated power with regard to smaller.If a total of L groups,
Then instantaneous power consumption is the 1/L of the total rated power of LED illuminator.That is instantaneous power section effect is (L-1)/L.Based on this principle by
In the reduction of instantaneous power, therefore the miniaturization for the supporting connecting wire of LED and accessory provides premise.
In summary：
1st, can be set within the specific limits most by regulating cycle length and dutycycle using the control method of the present invention
Low brightness values B2.Brightness and electric energy so can be flexibly adjusted as needed.
2nd, using the luminous LED device of control method of the invention on the premise of it can meet appropriateness illumination, with conventional work

Write.
3rd, due to having used control method of the invention, the instantaneous power of LED component is greatly reduced, and the LED component exists
Actual power during use is far smaller than the rated power of whole LED component；Such as needed in the vcehicular tunnel away from civil power
The place of low illumination is wanted, is powered using solar energy photovoltaic system, then the capacity of photovoltaic system and battery can be greatly lowered
It is required that buying and the installation cost of equipment can so be greatly lowered.
