1 Solar controller -6601D Solar controller LAWN LANTERNS 6601D (traduction automatique en «anglais BETA» avec l'outil Google à partir du document technique en «chinois simplifié») Profile : products. Solar LAWN LANTERNS mainly use solar energy to work,when too much sunlight in the daytime solar cells, light energy into electrical energy stored in batteries.by battery in the evening for LAWN LANTERNS LED (light emitting diodes) to provide power.the major advantages for their safety, energy-saving, convenient and environmental protection. Solar LAWN LANTERNS controller is developed in accordance with the special characteristics of solar LAWN LANTERNS work using DIP8.SOP8 package to facilitate production.main functions include driving circuit, and pulse width modulation control circuit photosensitive circuit.the controller with high conversion efficiency : 80~85% (typical values).solar power can be reduced version; Low Voltage : 0.9V start (maximum);adjustable output current characteristics. Features : 80~85% : high efficiency (typical values), can take full advantage of solar cells Scope : V voltage (single-rechargeable batteries) Adjustable 10 to 40 ma input current range : Low voltage so that it can ensure adequate lighting lamps in the dark outside when it opened Schmidt performance so that it can control is to ensure the stability of conversion lamps Brightness Overdischarge protection function can choose driven by rechargeable batteries : single rechargeable batteries apply various color LED LED Scope : Input Current conditions Connection scope of application objects LED accept any suitable 10~30mA a single color LED LED series for only two 10~40mA yellow, red Parallel 10~50mA suited to white, blue, green, phototherapy 10~50mA suited to three parallel white LED, blue, green Application Battery : single rechargeable battery-driven Apply various color LED LED Scope : Conditions Connection Input current range Connection Practical application of object ONE LED Single then 10~30mA Parallel suitable for the single color LED TWO LED Series 10~40mA For yellow, red Parallel 10~50mA Suited to white, blue, green, phototherapy Three LED Parallel 10~50mA Suited to white, blue, green

5 Solar controller -6601D LAWN LANTERNS regulating circuit 1, outside lighting brightness control switch regulating circuit (1) solar cells as the photodetector Adjust brightness light of the decision by the ratio R2/R3 fixed : When R2, R3 increase,dark lighting circuits need more open; Instead, R3 reduced, more open-lighting circuit. (2) photosensitive resistance as a photodetector Usually around R3 100 K for the outside world to control the brightness of the light from the photosensitive resistance characteristics of the decision. 2, the battery overdischarge protection Voltage Regulator Battery over-voltage protection up from R4, R5 pressure over the decision, but also with the pressure drop of the transistor.numerical experience as follows : R4=360K, R5=330K voltage : 1.15V R4=330K, R5=330K voltage : 1.05V Trend : R4/R5 greater voltage. Excessive use of the circuit up protected mode, we can fully extend LAWN LANTERNS brightened time.when the battery voltage is reduced voltage protection circuit to reduce current consumption, low voltage current smaller.as circuit reduces the current, batteries discharge at the time have greatly extended.through the use of this character, we can achieve high brightness LAWN LANTERNS previous few hours.medium intensity to maintain the effect after a few hours.the advantage is, first, even reduce the size of solar cells, LAWN LANTERNS brightened still have time to fully guarantee; Secondly,As for the discharge of the battery overdischarge protection, extending the life of electrical energy storage tank.
