What is the primary function of lighting equipment?
Category:
【概要内容】Lighting equipment consists of a light source, a lampshade, and accessories.
Lighting equipment consists of a light source, a lampshade, and accessories.
A. Lighting equipment is classified into two categories based on the functions of decorative lights and functional lights.
1. Decorative lighting, through the combination of decorative components and light sources, is primarily intended to meet the aesthetic requirements of architectural art in terms of pleasing form, while also appropriately addressing such considerations as lighting efficiency and glare prevention.
2. The function of luminaires is to redistribute the luminous flux of the light source, enhance lighting efficiency, and prevent glare, thereby creating an appropriate lighting environment. In special lighting environments characterized by humidity, corrosiveness, explosiveness, or flammability, the lampshade also serves to provide isolation and protection.
Secondly, lighting equipment is classified into two categories based on its application: indoor lighting and outdoor lighting.
1. Indoor lighting fixtures are typically classified according to the proportion of total luminous flux distributed in the upper and lower hemispheres of the space. Accordingly, the International Commission on Illumination recommends that lighting fixtures be categorized into five types: direct, semi-direct, uniform diffused, semi-indirect, and indirect. The following table shows the light distribution and lighting characteristics of different types of luminaires.
2. Outdoor lighting primarily consists of floodlights. Floodlights, also known as spotlights, are high-intensity light sources that use reflectors, lenses, and grilles to confine the light beam within a narrow three-dimensional angle; they are commonly employed for nighttime illumination of large buildings.
