Key points of design: If the light source is not treated, the efficiency of the light source can not be fully exerted, nor can it meet the needs of indoor lighting environment, and sometimes it will cause the harm of glare. Direct light, reflected light, diffused light and transmitted light have different uses in indoor lighting. If there are too many bright spots in a room, it will not only interfere with each other, but also waste energy; If there is too much diffused light, the indoor atmosphere will be dull because of the lack of contrast, and even people's misjudgment of space will be affected because they can't strengthen the space volume of objects.
Therefore, using the optical characteristics of different materials, using the transparency, opacity, translucency and different surface textures of materials to make various lighting equipment and devices, redistributing illumination and brightness, and changing the direction and performance of light emission according to different needs are the main problems that indoor lighting should study. For example, bright silver-plated reflectors are used for directional lighting, or as spotlights for sculptures, paintings, etc. Frosted glass or plastic lampshade made of acid etching or sandblasting can form diffuse light and increase the soft light in the room.
Lighting mode:
If the bare light source is not treated, it will not give full play to the efficiency of the light source, nor can it meet the needs of indoor lighting environment, and sometimes it will cause the harm of glare. Direct light, reflected light, diffused light and transmitted light have different uses in indoor lighting. If there are too many bright spots in a room, it will not only interfere with each other, but also waste energy; If there is too much diffused light, the indoor atmosphere will be dull because of the lack of contrast, and even people's misjudgment of space will be affected because they can't strengthen the space volume of objects.

Before indoor lighting design, we should first consider the overall lighting situation of the whole space. If the indoor lighting itself is better during the day, there is no need to design too many lamps for the day. However, if the indoor lighting is poor and it is dark in a relatively closed space, it is necessary to design more lighting under the lighting conditions. When designing indoor lighting, we should not only consider the brightness of the whole space, but also consider the utilization rate of resources to ensure environmental protection and energy saving.
