Abstract

A LED illumination apparatus (100) comprises at least one LED module (11) and a driving module (12). The LED module (11) includes a substrate (111) and a plurality of LED lighting sources (112) arranged on the substrate. The LED lighting sources (112) are electrically connected to the substrate (111). The driving module (12) includes a driver (121) and a shaft (122) connected to the driver. The shaft (122) is positioned in one side surface of the substrate (111). The substrate (111) can be rotated by the driver (121), adjusting the illumination angle of the LED module (11) and change the luminous distribution of the LED illumination apparatus (100).
