Embodiment
Lighting circuit principle in extra exit of the present invention is as shown in figure 1, including power circuit, battery management circuit, LED drivings
Circuit, light Acquisition Circuit and timing controller circuit, power circuit connection battery management circuit, battery management circuit connection
LED drive circuit, LED drive circuit connection LED lamp panel, light Acquisition Circuit connects LED by timing controller circuit and driven
Circuit.The luminous plate of extra exit sign is made of luminescent powder, in the case of light, luminescent powder is at 1 hour or so storage
After the luminous energy release deposited, energy is filled to luminescent powder with LED backlight plate, the work(of duration time length after energy-conservation and power-off is realized
Energy.
Inverse-excitation type switch power-supply circuit is as shown in Figure 2.
Battery management circuit is as shown in figure 3, TP5410 is the special single-unit charger for lithium ion battery of a portable power source
With constant 5V boost pressure controllers, charging part diversity high-accuracy voltage and battery regulator, preliminary filling, charged state are indicated and filled
The functions such as electricity cut-off can export maximum 1A charging currents in one.And booster circuit uses the zero load that CMOS techniques are manufactured
The extremely low VFM switching mode DC/DC boost converters of electric current.It has extremely low no-load power consumption（Less than 10uA）, and it is defeated to boost
1A can be reached by going out current drive capability., can be with plug and play without external key.Live part is linear voltage decreasing mode, built-in
PMOSFET, adds anti-back flow circuit, so not needing external sense resistor and isolating diode.Thermal feedback can be to charging electricity
Stream automatically adjusts, to be any limitation as under the conditions of high-power operation or high environment temperature to chip temperature, full of voltage
It is fixed on 4.2V.Charging current can carry out outside setting by a resistor.After battery reaches 4.2V, charging current
Setting electric current value 1/5 is gradually decreased down, TP5410 will terminate charging automatically.The same built-in power NMOSFET in boosting part,
Less internal resistance can provide driving force and reach 5V/1A.Higher integrated level causes TP5410 only to need a small amount of peripheral components
Can normal work.TP5410 is also integrated with charging temperature protection, and boost input power current limliting loop, can be according to loading condition
Dynamic regulation electric current, and with quick response and overcurrent turn-off function function.Boost converter is therefore more domestic by the way of frequency conversion
Outer like product has extremely low no-load power consumption, ripple, stronger driving force, and higher efficiency.
As shown in Figure 4 and Figure 5, PT4110 is a efficient boost conversion chip to LED drive circuit, and it uses single-unit
Lithium battery power supply can drive multichannel white light LEDs, and single channel series connection is up to 8.And can maintain system high efficiency it can modulate
White light LEDs operating current, reaches the effect of regulation LED brightness.Its main modulatory pathway has two kinds, is PWM respectively
With the HVDC Modulation method for changing feedback resistance value.The chip uses 300mv feedback voltage, can be substantially reduced power consumption, carry
High efficiency.PT4110 possesses many self-protection functions, such as open-circuit-protection, the overcurrent protection of Cycle by Cycle.Overtemperature protection, input
Under-voltage protection, and soft start function.
Intensity collection circuit is as shown in fig. 6, intensity collection uses photo resistance NTC, when intensity of illumination change is that NTC is electric by force
Resistance resistance drastically declines, and can obtain intensity signal by measuring the cloudy value of NTC resistance.
