Lighting works include road lighting, urban night scene lighting, indoor lighting, building lighting and other works.

The contents of lighting engineering include research and manufacture of light sources, lamps and control systems, measurement of luminosity and chromaticity, visual evaluation, etc. Especially the basic theory of modern lighting, the measurement of light, electric light sources, lighting fixtures, lighting regulations and standards, as well as the qualitative analysis and basic quantitative calculation of various light sources and lighting technologies.

The working procedure of lighting engineering is generally as follows: lighting engineering designers carry out lighting engineering installation, commissioning, acceptance and other activities through lighting design and technicians.
