Light art or luminism is a visual art form in which light is the main medium of expression. It is an art form in which either a sculpture produces light, or light is used to create a "sculpture" through the manipulation of light, colours, and shadows. These sculptures can be temporary or permanent, and can exist in two distinctive spaces: indoor galleries, such as museum exhibits, or outdoors at events like festivals. Light art can be an interaction of light within an architectural space. Light artists are those that devote all their creative experimentation to light art, some artists experiment with light and neon signage and use light in their practice.

Lumino Kinetic art is a subset and an art historical term in the context of the more established kinetic art, which in turn is a subset of new media art. The historian of art Frank Popper views the evolution of this type of art as evidence of "aesthetic preoccupations linked with technological advancement" and a starting-point in the context of high-technology art. László Moholy-Nagy (1895–1946), a member of the Bauhaus, and influenced by constructivism can be regarded as one of the fathers of Lumino kinetic art. Light sculpture and moving sculpture are the components of his Light-Space Modulator (1922–30), One of the first Light art pieces which also combines kinetic art.
