Abstract
A light apparatus for providing a light beam contains a driver circuit, a LED plate, a central lens, a surrounding lens. The LED plate has a luminous area to emit light. The central lens has a bottom surface and a top surface. The bottom surface of the central lens faces to the luminous area. The top surface has multiple lens. The surrounding lens has a surrounding surface connecting to and surrounding the top surface of the central lens. The surrounding lens has a lateral part gradually climbing upwardly away from the luminous area. There are multiple refraction lens disposed on the lateral part.
