①Direct lighting
The light is emitted through the lamps, and 90%-100% of the luminous flux reaches the working 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 dominance of the working surface in the entire environment, but due to the high brightness, glare should be prevented. Such as factories, general offices, etc.
②Semi-direct lighting
The semi-direct lighting method is that the lampshade made of translucent material covers the upper part of the light source, more than 60%-90% of the light is concentrated to the working surface, and 10%-40% of the light from the cover is diffused upward by the translucent lampshade. , the light is softer. This luminaire is often used for general lighting in lower rooms. Since the diffused light can illuminate the flat ceiling, the ceiling height of the room is increased, which can produce a higher sense of space.
③Indirect lighting
The indirect lighting method is the lighting method of indirect light generated by shading the light source, in which 90%-100% of the luminous flux is reflected on the working surface through the ceiling or wall, and the light below 10% directly illuminates the working surface. There are usually two treatment methods, one is to install an opaque lampshade on the lower part of the bulb, and the light is reflected on the flat top or other objects as indirect light; the other is to set the light bulb in the lamp slot, and the light is reflected from the flat top to the room into indirect light. When this lighting method is used alone, pay attention to the heavy shadows on the lower part of the opaque lampshade. It is usually used in conjunction with other lighting methods to achieve special artistic effects. Shopping malls, clothing stores, conference rooms and other places are generally used as ambient lighting or to improve scene brightness.
④ Semi-indirect lighting
The semi-indirect lighting method is the opposite of semi-direct lighting. The translucent lampshade is installed at the lower part of the light source, and more than 60% of the light is directed to the flat top to form an indirect light source, and 10%-40% of the light is diffused downward through the lampshade. This method can produce a special lighting effect, which makes the lower room feel taller. It is also suitable for small spaces in the house, such as halls, aisles, clothing stores, etc. This lighting method is usually used in a learning environment, which is most suitable.
⑤Diffuse lighting method
Diffuse lighting is to use the refraction function of lamps to control glare and diffuse the light around. This kind of lighting generally has two forms, one is that the light is emitted from the upper opening 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 seal all the light to produce diffusion. This type of lighting has soft light performance and visual comfort, suitable for bedrooms.
