Abstract
A lighting apparatus includes a lens, a cup housing, a light source and a top cover. The cup housing has a surrounding wall and a light source holder. The cup housing is installed on a fixed platform. The light source is placed on the light source holder. The cup housing and the top cover form a container space for storing the lens and the light source. A top end of the lens is attached to the top cover. A second end of the lens faces to the light source. A relative distance between the lens and the light source is adjustable to change a light pattern of a output light of the light source. The output light is a light of the light source passing through the lens.
