Projection lamp is a lamp that designates the illumination on the illuminated surface to be higher than the surrounding environment. It is capable of aiming in any direction and has a structure that is not affected by weather conditions. The angle of the projected beam of a floodlight varies widely from 0° to 180°, and those with a particularly narrow beam are called searchlights. Floodlights, when projected from a height, provide a significant increase in the spatial brightness of the environment, with a large light coverage that gives a daytime-like appearance, and therefore a high quality of illumination and visual effect.

Projection lamp is through the optical principle of the image or light projected onto the wall, ceiling or other flat surface of a lamp. Compared with traditional lighting equipment, the biggest feature of the projection lamp is that it can create a rich variety of visual effects, from simple patterns to complex dynamic scenes, and even interactive light and shadow experience, all show its unique charm as a “light and shadow magician”.
