Concentrated light source: The light of the centralized light source is a direct light, which focuses the direct light on a limited area so that you can clearly see the ongoing actions, especially when working, reading, cooking, and dining. Need a centralized light source. Since the shape of the lamp shade and the position of the lamp determine the size of the beam, the direct lamp is usually equipped with a cover or a cooling air hole, and the lamp cover is an opaque lamp such as a spotlight, a track lamp, and a work lamp.
Auxiliary light source: Centralized light source has a large illumination intensity. Eyes are prone to fatigue for a long time in this environment. At this time, you need an auxiliary light source, such as a stand light, a book light, etc., to reconcile the indoor light difference. The eyes feel comfortable. The light of the auxiliary light source is diffuse light, and the light that it spreads to all corners of the house is the same. In general, lamps with scattered light should be used with a direct light.
Primarily light source: Ceiling light is a light source, usually it is the main light in the house, also known as the background light, it can enhance the indoor light source to a certain brightness, the same room to provide the same light, so it will not produce significant There is no serious contrast between the shadows of light and the places where they are not photographed. However, since it must be used with other lights, it should not be very bright. Compared with other light sources in the home, it has the lowest brightness.
In short, this “golden rule of 5:3:1 lampâ€, the so-called “5†refers to the concentrated light with the highest brightness, such as a projector lamp; “3†refers to the auxiliary type that gives a soft feeling Light source; "1" is the light source that provides the most basic lighting of the entire room.
