1. A lighting equipment comprising:
- a plurality of light-emitting units, each of the light-emitting units comprising;
a light source, anda bulk-shaped lens body identified by a top surface, a bottom surface and a contour surface, implementing a well-shaped concavity in the inside of the lens body, the concavity being aligned to the top surface from the bottom surface along an optical axis of the lens body so as to install the light source, a distance between a ceiling surface of the concavity and the top surface along the optical axis is larger than a radius of curvature of the top surface; and
a power supply unit connected respectively to the light-emitting units, configured to supply electric power to each of the light source.

Abstract
The lens embraces a bulk-shaped lens body identified by a top surface, a bottom surface and a contour surface, and a well-shaped concavity is implemented in the inside of the lens body, aligned from the bottom surface toward the top surface. The lens body has geometry such as bullet-shape or egg-shape. A ceiling surface of concavity implemented in the lens body serves as a first lens surface, the top surface of the lens body serves as the second lens surface, and inside of the concavity serves as a storing cavity of a light source or a photodetector.
