1. A lighting apparatus, comprising:
a lens;
a cup housing having a surrounding wall and a light source holder, wherein the cup housing is installed on a fixed platform;
a light source placed on the light source holder; and
a top cover, wherein the cup housing and the top cover form a container space for storing the lens and the light source, wherein a top end of the lens is attached to the top cover, wherein a second end of the lens faces to the light source, wherein 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, wherein the output light is a light of the light source passing through the lens, wherein the lens is rotated with respect to the top cover to change the relative distance to the light source, wherein the lens has a handle to be held for rotating the lens with respect to the top cover, wherein a connector couples the top cover and the lens for selecting the relative distance from multiple discrete values, wherein the connector has several segment points for the lens to stay unless an external force larger than a predetermined value is applied on the lens.
