There Are Several Ways Of Indoor Lighting

There are several indoor lighting methods commonly used at present. According to the spatial distribution of the luminous flux of the luminaire and the installation method of the luminaire, indoor lighting can be divided into five types:

1. The direct illumination light is emitted through the luminaire, and 90%-100% of the luminous flux reaches the assumption. On the work surface, this lighting method is direct lighting. This lighting method has a strong contrast between light and dark, and can create interesting and vivid light and shadow effects, which can highlight the dominant position of the work surface in the entire environment, but due to the high brightness, the generation of glare should be prevented. Such as factories, general offices, etc.

2. Semi-direct lighting The semi-direct lighting method is that the lampshade made of translucent material covers the upper part of the light source, and more than 60%-90% of the light is concentrated on the working surface, and 10%-40% of the covered light passes through the translucent lampshade. Diffuse and diffuse upward, the light is softer. Such lamps are often used for general lighting in lower rooms. Because the diffused light can illuminate the flat roof, the height of the top of the room is increased, which can produce a higher sense of space.

3. Indirect lighting: indirect lighting is a lighting method of indirect light generated by shielding the light source, in which 90%-100% of the luminous flux acts on the working surface through the ceiling or wall reflection, and the light below 10% directly illuminates the working surface. There are usually two treatment methods. One is to install the opaque lampshade on the lower part of the bulb, and the light is reflected to the flat top or other objects as indirect light; the other is to set the bulb in the lamp trough, and the light is reflected from the flat top to the room. Indirect light. When this lighting method is used alone, pay attention to the heavy shadows at the bottom of the opaque lampshade. It is usually used in conjunction with other lighting methods to achieve special artistic effects. Places such as shopping malls, clothing stores, meeting rooms, etc., are generally used as ambient lighting or to increase the brightness of the scene.

4. Semi-indirect lighting: Semi-indirect lighting is the opposite of semi-direct lighting. The translucent lampshade is installed under the light source, and more than 60% of the light is directed to the flat top to form an indirect light source. 10%-40% of the light is directed by the lampshade. Down diffusion. This way can produce a special lighting effect, so that the lower room has a sense of heightened. It is also suitable for small spaces in residences, such as entrance halls, aisles, clothing stores, etc. This type of lighting is usually used in a learning environment and is most appropriate.

5. Diffuse lighting method: diffuse lighting method uses the refraction function of the lamp to control the glare and diffuse the light around. There are basically two forms of this kind of lighting, one is that the light is emitted from the upper mouth of the lampshade and reflected by the flat top, the two sides are diffused from the translucent lampshade, and the lower part is diffused from the grille. The other is to use a translucent lampshade to completely enclose the light to produce diffusion. This kind of lighting has soft light performance and comfortable vision, which is suitable for bedrooms.
