The present invention relates to a lens optical system for the control of light distribution and an LED group lighting device including the same. The lens optical system is a lens structure, formed of a transparent material, but including a light diffusion lens, designed in a particular outer shape to form a line type band structure. Multiple LED light sources are integrated into one single lens system in order to tune light distribution, still have advantageous parts of the existing COB type LED package and the existing POB type LED package, and improve weak parts of each part. Moreover, the entire brightness is reduced in order to remove a dazzling phenomenon, produce the system at a low cost, and show an excellent radiation property. |
