Abstract
A LED array flash for cameras includes a LED array and a controller. The LED array consists of at least one LED light source with first order lens. The LED light source may be further covered with a second order lens. Thus an oblong or round distribution pattern with uniform light intensity is emitted. The controller is used to control flash modes such as low brightness continuous lighting or high brightness pulse lighting with lighting time control so as to save power and avoid overheating.
