Abstract

A focusable lighting system is provided, comprising a base body, a first light source light source, a cover body, second light sources, convex lenses, and focus controllers. The first light source is disposed on the front surface portion of the base body. The cover body has a front opening portion connected to an inside of the cover body, a rear cover portion, top and bottom edge portions provided between the front opening portion and the rear cover portion, and two side portions. Each focus controller is installed on each convex lens in the inner space portion of the cover body and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light.
