A downlight is often referred to as a spotlight. The downlight is a lamp that specifies that an illuminated surface has an illuminance greater than that of the surrounding environment. It can be aimed in any direction and is not affected by weather conditions. The downlight is commonly used in places such as mines, building outlines, stadiums and ball fields where a relatively large light coverage is required. This lamp has a particularly narrow beam, and is also referred to as a searchlight.
A floodlight is a point source of light. The floodlight can illuminate evenly in all directions, and has an illumination range that can be arbitrarily adjusted. The floodlight appears as an octahedral icon in the scene and is often used in renderings or as a light source during photography. The light of the floodlight is highly diffuse and has no direction. A light emitted by the floodlight fades much more slowly than a light emitted by the spotlight, and some floodlights fade very slowly, acting like a light source that does not cast shadows. The light projected by the spotlight is directional and well-defined, and can illuminate a specific area.
The downlight and the floodlight are both commonly used lamps in lighting engineering; however, they have certain differences. First, the illumination pattern of the floodlight is diffuse. The downlight has a light-gathering function and can be directed to a specified direction.
In order to adapt to various use environments, a lamp integrating a spotlight and a floodlight by using a double-lens combination mode appears, for example, spotlighting or floodlighting can be implemented by replacing a lens, or spotlighting or floodlighting can also be implemented by focusing and emitting a cover plate through a distance between a cover plate light source and a convex lens. However, there is a movable stroke in the middle when the distance between the light source and the convex lens is changed, and a larger stroke is needed to obtain a wide range of spotlighting and floodlighting; consequently, the size of the lamp becomes very large, and this method cannot achieve control of a precise reflection angle, making it difficult to obtain a satisfactory spotlight effect.
