Desktop LED Light Circuit:
You can create AN ultra-simple desktop emergency light-weight exploitation ‘discharged’ batteries. you recognize that battery cells still have goodly energy left in them even once these become ‘weak’ for many powered devices. Here may be a thanks to extract their leftover power to be used in such applications as emergency light-weight.
The crystal rectifier light-weight delineated here will be supercharged off any one.5V or perhaps a drained one.2V battery cell. Fig. one shows author’s model and Fig. two shows the 1W white crystal rectifier used.
Circuit and dealing
Fig. three shows the circuit diagram of desktop crystal rectifier emergency light-weight that contains a mix of a joule felon circuit, a 1W white crystal rectifier chip and a blackout detector section.

Construction and testing:
An actual-size, single-side PCB for the emergency lightweight is shown in Fig. four and its part layout in Fig. 5. once aggregation the circuit on PCB, enclose it in a very appropriate plastic box. once 230V AC mains provide is offered, white LED is off irrespective of the position of switch S1. once AC mains provide is off, switch S1 ought to be closed to create white LED glow and opened to change it off.
For the winding on solid core, take alittle solid core (for example, one with 10mm outer Defense Intelligence Agency and 5mm height). Wrap a 36SWG enamelled copper wire round the solid core to create ten turns. Repeat the winding with the second piece of 36SWG enamelled copper wire. the 2 windings (L1 and L2) ought to be in opposite directions. The polarities of the windings square measure shown by the dots within the circuit. currently be a part of nearest ends of the coils along, as shown in Fig. 6. This forms the centre pole that is connected to positive terminal of the battery. Before victimization the circuit, verify the voltages square measure as per table.
