Abstract
A lighting apparatus includes a light source plate, a light passing cover and a surface rim. The light source plate is mounted with LED modules and a driver circuit. The light passing cover has a circular curved surface. The circular curved surface has a first diameter. A curvature of the circular curved surface is a first radius of a corresponding osculating circle. A ratio between the first diameter to the first radius multiplied with two is between 0.25 to 0.75. The surface rim has a central concave platform for disposing the light source plate. The driver circuit converts an external power source to a driving current supplied to the LED modules to emit a light passing through the light passing cover.
