Indoor LED lighting classification guide
The classification of LED lighting have many ways, for example, by usage and by type of illumination. Different lighting fields have different LED model, their usage is not the same. LED lighting in the field of appropriate lighting applications can play their greatest advantages, the following detailed is to analyze the classification of LED indoor lighting.
Classify by type
Direct LED lighting: direct lighting is light through the lamp after the injection, 90% -100% of the luminous flux to the assumed working surface, resulting in a strong light contrast and vivid light and shadow effects, can highlight the face in the whole environment in the lead status, mainly in the workplaces.
Semi-direct LED lighting: semi-direct lighting refers to the use of translucent material made of the lamp cover the upper part of the light source, so that 60% -90% of the light focused on the work surface, in addition, the cover will be 10%-40% proportion of the translucent shade after the spread of diffuse up. The light generated by the lighting method is relatively soft, upward diffuse light can increase the sense of space, mainly for the lower level of the room.
Indirect LED lighting: Indirect lighting refers to the light source of the indirect light generated by the lighting, where 90% -100% of the luminous flux through the ceiling or wall reflection on the face. The remaining less than 10% of the light directly expose to the work surface. In general, this way of lighting only in conjunction with other lighting methods to obtain a special artistic effect, mainly for shopping malls, clothing stores, conference rooms and so on.
Semi-indirect LED lighting: semi-direct lighting compared to semi-direct way, semi-indirect lighting is a completely opposite way of lighting, specifically the translucent shade is installed in the lower part of the light source, making more than 60% of the light shot flat, Thus forming an indirect light source, and the remaining 10% -40% of the light is diffused down through the lampshade. This way can produce more obvious lighting effects, so that lower the room to produce a certain sense of rising. It’s mainly applicable to the smaller part of the residential space, such as foyer, aisle and so on.
Diffuse LED lighting: diffuse lighting refers to the use of lighting refraction function to control the glare, which will spread to the surrounding diffuse. This kind of lighting is generally in two forms, one is the light from the shade of the shell by the flat-top reflection, both sides from the translucent shade spread, and the lower part of the spread from the grille. The other is to use a translucent shade to cover all the light and produce diffuse. The light produced by such lighting is visually comfortable and suitable for use in bedrooms, rooms and so on.
