There are many classification methods for chandeliers, such as classification according to use, classification according to the distribution ratio of luminous flux recommended by CIE, classification according to dustproof, moisture-proof, electric shock-proof grades, etc. According to the recommendations of the International Commission on Illumination (CIE), chandeliers are divided into five categories according to the proportion of luminous flux in the upper and lower spaces: direct type, semi-direct type, fully diffused type (including direct-indirect type with little light in the horizontal direction), semi-direct type Indirect and indirect.

Direct type lamps and semi-direct type chandeliers
Most of the luminous flux (90-100%) of this type of direct-type lamp is directly projected below, so the utilization rate of the luminous flux of the modern chandelier is the highest.
Most of the luminous flux (60-90%) of this type of semi-direct chandelier shoots into the lower hemisphere space, and a small part shoots upward. The upward component will reduce the hardness of the shadow produced by the lighting environment and improve the brightness of its surfaces.
Diffuse and direct-indirect chandeliers
The luminous flux of the modern chandelier up and down is almost the same (40%-60% each). The most common is the opalescent glass spherical lampshade, and other closed lampshades of various shapes that diffuse light have similar light distribution. This luminaire casts light evenly in all directions, so the utilization of light flux is low. Use the scene selector to work with light sources and low-voltage lighting systems, combining flexible lighting designs and multi-point control with common wiring. It is suitable for conference rooms, museums, and other places, and is convenient, flexible, and has a remarkable control effect.
Semi-indirect lighting luminaire
The downward luminous flux of modern chandeliers accounts for 10%-40%, and its downward component is often only used to generate brightness commensurate with the ceiling. Excessive or improper distribution of this component will also cause some defects such as direct or indirect glare. A translucent cover with the upper opening falls into this category of the modern chandelier. They are mainly used as architectural decorative lighting. Since most of the light is cast to the ceiling and upper walls, the indirect light in the room is increased, and the light is softer and more pleasant.
Indirect lighting luminaire
A small portion of the light flux (below 10%) of the modern chandelier is downward. When the design is good, the entire ceiling becomes a lighting source to achieve a soft and shadow-free lighting effect. Since the modern chandelier has very little downward light flux, as long as the arrangement is reasonable, the direct glare and reflected glare are very small. The luminous flux utilization rate of such lamps is lower than the previous four.
