计划经济时代

The era of planned economy

自然光占据上风

Natural light takes up the upper wind

照明方式：自然光＋蜡烛

Lighting mode: natural light + candles

调光方式：依靠建筑的门窗、窗帘等方式进行调节控光。

Dimming way: rely on building windows and doors, curtains and other ways to control light.

显然，这个时代的作息时间表就是天黑了就要回家，并不是不想逛街，而是黑灯瞎火的实在没辙；另一个方面，光线对于建筑的稀缺也使得西方商业建筑和国内部分商业用建筑的采光都特别用心计算和设计。九游J9 老生常谈的“用光线做设计”，那时才是真正的起点。

It is clear that the time schedule of the time is to go home in the dark, not to go shopping, but to make the dark and blind. On the other hand, the scarcity of light in architecture has also made the western commercial buildings and some commercial buildings at home particularly careful calculation and design. Our commonplace "design with light" is the real starting point.

改革开放时期

The period of reform and opening to the outside world

白炽灯成绝对主角

Incandescent lamp is an absolute protagonist

照明方式：白炽灯

Lighting mode: incandescent lamp

调光方式：因使用普通白炽灯、简易灯具等方式，几乎无控光可言。

Dimming mode: because of the use of ordinary incandescent lamps, simple lamps and so on, almost no light control.

1980-1990 years

LFL荧光灯兴起

The rise of LFL fluorescent lamps

照明方式： LFL 荧光灯管成为当时主要的照明光源。

Lighting mode: LFL fluorescent lamp became the main lighting source at that time.

控光方式：这个时代刚好是改革开放的试水期，各种商品的种类和样式开始慢慢丰富起来，直管荧光灯开始普及，把商店的灯光从昏黄中解放出来。总算不是黄昏的感觉了，但也只是使用简易灯具和简单支架，虽节能但无控光，效果是眩光＋惨白。

Light control: this time is just the trial period of reform and opening, the variety and style of various commodities began to enrich slowly, the fluorescent lamp began to popularize, and the lighting of the store was liberated from the yellow. It's not the feeling of dusk at last, but it's only using simple lamps and simple stents. Although it saves energy but does not control light, the effect is glare + pale.

1990-1995 years

荧光灯受热捧

The fluorescent lamp is hot

照明方式：大中小各种荧光灯应用爆发，商店越来越亮。

Lighting mode: all kinds of fluorescent lamps in large and medium sized areas are booming, and shops are getting brighter.

控光方式：商品和各种服务进入极大丰富的阶段，人们开始追求视觉上的刺激，最直接简单的方式就是利用大量的灯把店弄得亮堂堂（技术用语叫均匀度和照度一起提高）。

Light control: goods and services have entered a very rich stage. People begin to pursue visual stimuli. The most direct and simple way is to make use of a large number of lights to make the shop bright. (technical terms are called uniformity and illumination).

技术上，荧光灯从直管开始有了螺旋、双U等应用。于是，在商业中大量使用节能管配合筒灯，从此时开始有了控光。但控光效果较差，基本上就是把荧光灯装进倒扣的碗里面。

Technically, fluorescent lamps start with straight tubes and have applications such as helix, double U and so on. As a result, a lot of energy saving tubes were used in business, and the lights were controlled from now on. But the light control effect is poor, basically is to put fluorescent lamp into the inverted bowl.

这是个很亢奋的时代，零售商业的模式进入第一个爆发期。虽然出现了很多“傻”亮的案例，但传统光源所表现出的光色品质还是相当不错的。

This is a very exciting era, and the mode of retail business has entered the first outbreak period. Although there are many "silly" cases, the light quality of traditional light sources is quite good.
