Abstract
A solar lamp drive circuit is arranged todelay start-up while a current is supplied to the lamp filament to warm up the filament. During operation, the back emf induced in the lamp is sampled, and if operating conditions deteriorate the current to the filament is reapplied automatically and the power supply to the lamp increased.
