Light installation refers to the artistic and functional use of lighting in various environments, such as public spaces, galleries, and events. These installations can enhance the atmosphere, create visual interest, and convey specific themes or messages. Artists and designers often use a combination of natural and artificial light sources to achieve their desired effects. Typically, light installations involve the use of materials like LED lights, neon tubes, or projectors to create dynamic displays. They can be temporary or permanent and are often featured in festivals, exhibitions, and urban settings. Notable examples include the Festival of Lights in Berlin and the Luminothérapie event in Montreal.
