商业照明灯具分两大类：商店内环境中的一般照明和陈列商品的照明（也称局部照明）。

There are two main categories of commercial lighting fixtures: general lighting and display lighting (also known as local lighting) in the store.

一般照明灯具的作用是提供商店内的环境照明需要的照度，达到店内通亮而且均匀的效果，也是顾客放松，精神舒缓，保证行走和购物环境需要的基本环境得到满足。这类灯具有筒灯、吊灯和嵌入/吸顶式灯具等。

The function of the general lighting is to provide the illuminance required by the environment in the store, to achieve a bright and uniform effect in the store, and to relax the customers, relax the spirit, and ensure the basic environment needed for the walking and shopping environment to meet the basic conditions. This kind of lamp lamp, chandelier and ceiling lamps / embedded.

吊灯和嵌入吸顶式灯具商业场所灯具陈列商品照明灯具的作用是采用在重要的或要让顾客关注的商品上提高照度形成更高亮度的效果，达到吸引顾客眼球或表现该对象纹理目的，常称为重点/加强照明。根据对象的体量或要求，采用不同功率和光束角的射灯，灯具安装在被照物的前上方的一个位置上。

The function of the lamps and lanterns on the display of lamps and lanterns in the commercial place of the ceiling lamps and lanterns is to improve the luminance of the illuminance on the goods which are important or to let the customers concerned, to attract the customers' eyeballs or to express the texture of the object, which is often called the focus / Qiang Zhaoming. According to the volume or requirement of the object, a spotlight with different power and beam angle is installed, and the lamp is installed at a position above the top of the object.

总结一下，灯具有以下共同要求：

To sum up, the lamps and lanterns have the following common requirements:

1）防眩光结构。

1) anti glare structure.

商业场所内的观察活动是非常随意的，眼睛会搜索到场所空间内的任何可能会引起兴趣的物品上。因此，选择灯具时，要注意通过灯具的亮度限制曲线了解它们的眩光水平，还应查看灯具的保护角。根据灯具的安装位置，在满足照度均匀度要求和节能要求的前提下，尽可能选择保护角大的灯具，将眩光降低至最低程度。

Observation activities in commercial establishments are very casual. Eyes will search for any objects that may arouse interest in the space. Therefore, when choosing lamps and lanterns, we should pay attention to understand their glare level through the luminance restriction curve of lamps and lanterns, and also check the protection angle of lamps and lanterns. According to the installation position of the lamps and lanterns, on the premise of satisfying the requirement of uniformity and energy saving, the lamps and lanterns with large protection angle are chosen as much as possible to reduce the glare to the lowest level.

2）显色性要求较高。

2) the coloration requirement is higher.

在商业场所照明下，商品呈现的颜色需真实，显色指数不应低于80。

In the lighting of commercial premises, the color of commodities should be real, and the color rendering index should not be less than 80.

3）紫外防护。

3) UV protection.

在商业场所内会使用高强度金属卤化灯的灯具作为一般照明灯具和局部重点照明，因此，需要了解灯具的关于紫外辐射的安全照度值，应用在低于安全照度值以下不会产生紫外伤害。选用带有透明玻璃或塑料罩的灯具可以有效地避免紫外的辐射。

The lamps and lanterns which use high strength metal halide lamps in commercial places are used as general lighting fixtures and local key lighting. Therefore, it is necessary to understand the safety illuminance value of ultraviolet radiation, which will not produce UV damage under the value below the safety illumination. The choice of luminaire with transparent glass or plastic cover can effectively avoid ultraviolet radiation.

4）射灯的光斑。

4) the light spot of the lamp.

射灯的光斑大小（光束扩散角）和中心光强是十分重要的两个指标，必须适合照明对象的要求。光斑中的均匀性也是十分重要的，选择能产生一个均匀光斑的灯具是十分重要的。

Spot size (beam diffusion angle) and center light intensity are two important indicators for spotlight, which must be suitable for lighting objects. Uniformity in the spot is also very important. Choosing lamps that produce a uniform spot is very important.
