Abstract
Official abstract text for this publication.
An LED flash module includes: a module substrate; an energy device disposed on the module substrate; an LED module arranged on the module substrate includes a plurality of LED blocks arranged in a first direction, each LED block including a plurality of LED elements which is arranged in a second direction perpendicular to the first direction and emits light with power supplied from the energy device; a charger circuit arranged on the module substrate to charge the energy device; and a control circuit arranged on the module substrate to control emission of LED elements. A wiring length from one of the LED elements to a plus terminal of a power supply portion supplying power to each of the LED elements and a wiring length from the one of the LED elements to a minus terminal of the power supply portion is substantially the same for all of the LED elements.
First claim
