Classified by type and method, direct LED lighting refers to the phenomenon where 90% -100% of the light flux reaches the assumed working surface after being emitted through a lamp, creating a strong contrast between light and dark and a vivid light and shadow effect. It can highlight the dominant position of the working surface in the entire environment and is mainly used in the workplace. Semi direct LED lighting: Semi direct lighting refers to using a semi transparent material lampshade to cover the upper part of the light source, so that more than 60% -90% of the light is concentrated on the working surface. In addition, 10% -40% of the covered light will diffuse upwards through the semi transparent lampshade. This lighting method produces relatively soft light, and the upward diffuse light can increase the spatial sense of the building, mainly suitable for rooms with lower heights.

Indirect LED lighting: Indirect lighting refers to the lighting method that produces indirect light by blocking the light source. 90% -100% of the light flux is reflected on the working surface through the ceiling or wall, and less than 10% of the remaining light is directly directed onto the working surface. Generally speaking, this lighting method can only achieve special artistic effects when used in conjunction with other lighting methods, mainly used in shopping malls, clothing stores, conference rooms, etc. Semi indirect LED lighting: Compared to semi direct lighting, semi indirect lighting is a completely opposite lighting method. Specifically, a semi transparent lampshade is installed below the light source, allowing more than 60% of the light to shine towards the flat top, forming an indirect light source, while the remaining 10% -40% of the light diffuses downwards through the lampshade. This method can produce a more noticeable lighting effect, creating a certain sense of elevation in lower rooms. Mainly suitable for smaller spaces in residential areas, such as foyers, corridors, etc.
