Working principle: in use, when from L, the alternating current that N electric wire is come in is through BD1 (bridge heap MB10F) full-wave rectification, C1 filtering (104/400V) just obtains a high voltage VDD+ in the anode of bridge heap.VDD+ voltage powers to entire circuit.By R1, R3, C2 Decompression network is formed, starting voltage is provided to 2 feet (VDD foot) of isolation drive module U1, starts inside isolation drive module U1 Work generates switch concussion, by D8 and R20 to 2 feet (VDD foot) continued power of U1 after concussion.In this way, VDD+ voltage is through T1 (isolating transformer) primary coil enters 5,6 feet (DRAN) of U1, then through U1 on-off action, passes through from 4 feet (CS foot) of U1 The cathode of R4, R5 arrival bridge heap.In this way, by bridge heap (BD1), C1 (CBB capacitor 104/400V), U1 (High Power Factor isolation Module) and peripheral component, TI (EE16 isolating transformer) just constitutes a High Power Factor isolation concussion network.T1 transformation After device concussion, secondary will have induced voltage.Induced voltage is rectified through D5 (ES2J) and the filter network of C5 composition, just obtains one A V+ voltage reaches B+, at B+, electric current after V+ voltage is to general lighting lamp bead plate (2 and 6 2835 lamp bead 0.5W of string) power supply Point both sides are walked, and one side B+ is charged by D3, the charging network of C3 composition to lithium battery (BT).Lithium battery (BT) is in charging shape State.Another side B+ reaches V1+ by D2 (M7), D4 (M7), D8 (M7) again, and V1+ is to give emergency lighting lamp plate (6 and 1 string 2835 0.5W lamp bead) supply voltage, in this way, emergency lighting lamp plate has a glimmer in general lighting；

When from L, when the mains failure that N electric wire is come in, by R9, R7, D6, ZD1, C4, D7, R18, Q3, R17, R19, The emergency conversion circuit of C8, Q2, R16, Q1 composition just will start, and Q1 (metal-oxide-semiconductor 2301) is in the conductive state, lithium battery anode VBAT passes through the DS foot of Q1, then passes through R12, reaches V1+ after the metering function of R13, gives emergency lighting lamp plate (6 and 1 string 2835 0.5W lamp bead) it powers, general lighting lamp plate (2 and 6 2835 0.5W lamp beads of string) does not work.Lithium battery (BT) is in discharge condition.Mould Block U2, U3 play the role of overcharging to lithium battery, Cross prevention；

When from L, the alternating current that N electric wire is come in is sent a telegram here again when, by R9, R7, D6, ZD1, C4, D7, R18, Q3, R17, R19, The emergency conversion circuit of C8, Q2, R16, Q1 composition may turn off, and Q1 (MOS pipe 2301) is in off state.General lighting work Make, lithium battery (BT) is in charged state.

Power factor refers in alternating current circuit, the cosine of the phase difference (Φ) between voltage and electric current be called power because Number, is indicated, numerically, power factor is the ratio of active power and apparent energy, i.e. cos Φ=P/S. with symbol cos Φ Power factor is low power factor 0.5 or so；Power factor is High Power Factor 0.9 or so.

Summary: driving plate has a biggish change, and general lighting is separated, 2 and 6 strings when general lighting with emergency lighting 2835 this group of all lights of lamp bead 0.5W, 16 and 2835 this group of glimmers of lamp bead 0.5W of string.2 and 6 2835 lamp beads of string when emergency lighting This group of 0.5W does not work, 16 and 2835 this group of all lights of lamp bead 0.5W of string, in isolation circuit, the secondary commutation pipe of isolating transformer (ES2J) it tails off, a D5 (ES2J)；It is also exactly adjustment size of current the resistance R4, R5 for connecing isolation drive module CS foot Change in resistance it is very big, CS foot resistance value becomes larger, and illustrates that the electric current exported after secondary commutation becomes smaller, in this way, rectifying tube just uses one D5 (ES2J) is just much of that.And power P=I*U, in the case where requiring the identical situation of power, electric current is reduced, it is necessary to voltage is increased, this Sample just needs to increase the string number of lamp bead, (2 and 6 strings, 2835,0.5W).The secondary of isolating transformer (EE13 is horizontal) after improving in this way The voltage for rectifying the secondary commutation output of the isolating transformer (EE13 is horizontal) than Fig. 1 is high, to reach 18-25V or so, electricity When road works, electric current is small, it consumes the power in isolation drive module with regard to small；It is consumed on isolation drive transformer Power with regard to small；The power consumed on rectifier diode is also small, and the power (line loss) consumed in the circuit board is also small.Therefore Fig. 2 Circuit efficiency can reach 92%, and light transmittance efficiency reaches 100LM/W or more.3): using super simple charging circuit (by D3, C3 group At).In general lighting, by D3, C3 composition charging network charges to lithium battery, by D2 (M7), D4 (M7), D8 (M7) and The circuit of emergency lighting lamp plate (6 and 1 string 2835 lamp bead 0.5W) composition, have pressure stabilizing 5.1V or so (lamp bead is depressured 3.0V, one A M7 is depressured 0.7V, 3 2.1V), there is charge protection effect to lithium battery.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
