In some embodiments, a lighting apparatus includes a back cover, a first light source, a second light source, a back cover, a first separator and a driver. The first light source is mounted on the back cover. For example, the first light source includes multiple LED modules mounted on a circular ring structure. The circular ring structure is fixed to the back cover. Each LED module may have a LED chip covered by a lens module for guiding an output light of the LED chip to desired directions, e.g. to form a condensed light beam or to diffuse evenly on a projected surface. |
