Earth is a planet on which there have always been periods of light and dark and our circadian rhythms are largely controlled by the sun. We have evolved to not only love light, but to need light: we see best in the light and have limited sight in the darkness;and since time began, light has allowed us to live productive lives, has kept the darkness away, and has met practical needs.

As the seasons change, we have access to more or less natural light, particularly in the Northern Hemisphere. Too little light leaves some of us depressed, suffering from seasonal affective disorder (SAD). Most people prefer to feel buoyant, not depressed, and getting enough light – even artificial light – means that it’s possible to keep sad and depressed moods at bay.

节能灯的工作原理是基于荧

# data[].attributes.body
节能灯的工作原理是基于荧光原理。荧光灯使用电子激发气体来产生紫外线，然后荧光粉将紫外线转换成人眼可⻅的可⻅光。在荧光灯的两端，有电极和气体注入口。电极产生一个电场，在气
体注入口将电子注入气体，使气体变成等离子体，产生紫外线并成为紫外线成像的目标。
The working principle of energy-saving lamps is based on the principle of fluorescence. Fluorescent lamps use electronic excitation of gases to produce ultraviolet rays, which are then converted into visible light visible to the human eye byfluorescent substances. At both ends of the fluorescent lamp, there are electrodes and gas injection ports. The electrode generates an electric field that injects electrons into the gas at the injection port, turning the gas into a plasma to produce ultraviolet becoming the target of ultraviolet imaging.

# data[].attributes.body
LED结构是发光二极管的核心部分是由p型半导体和n型半导体组成的晶片，在p型半导体和n型半导体之间有一个过渡层，称为p-n结。在某些半导体材料的PN结中，注入的少数载流子与多数载流子复合时会把多余的能量以光的形式释放出来。

The core part of the light-emitting diode is a wafer composed of a p-type semiconductor and an n-type semiconductor,  there is a transition layer between the p-type semiconductor and the n-type semiconductor, called the p-n junction. PN junction in some semiconductor materials, the injection of a few carriers and the majority of carriers compound will release excess energy in the form of light.

白炽灯广泛被人使用的一种

# data[].attributes.body
白炽灯广泛被人使用的一种光源，它能散发出温暖晕黄的光线，是我们大多数人所认为的灯泡。它的价格便宜，开灯即亮、可连续调光、结构简单。因此，钨丝灯泡也具有多变的式样以搭配不同的灯具。然而，钨丝灯泡的寿命并不长久，光效低，也不省电，它还会发出不低的温度，所以不可以距离纸张、纺织品或朔胶制品太近。Widely used as a light source, it emits a warm, yellowish light, and is what most of us think of as a light bulb. It is cheap, has good color rendering ,lights on, can be continuously dimmed, and has a simple structure. Therefore, tungsten bulbs also have a variety of styles to match different lamps. However, tungsten bulbs do not have a long life, low luminous efficacy, and are not energy efficient. They also emit a high temperature, so they should not be used too close to paper, textiles, or plastic products.

蜡烛熔化后形成液态燃料会被芯质吸收，芯质中的连续燃烧，进一步消耗蜡的固体部分，这种动态平衡维持了蜡烛持续燃烧的特性。芯质可以是棉花，麻绳或其他有机纤维，而蜡则通常是蜂蜡、芒硝蜡或苦橙蜡。The working principle of the candle is to use fire to burn short columnar wax. When burning, the heat source melts the wax, the liquid wax is led to the core, the heating pressure evaporates, the steam is mixed with the air to produce combustion, and at the same time, the other solid wax is continuously melted and burned, thus constantly providing the heat and fuel needed for Keep burning. At the same time, the liquid fuel formed after the candle is melted will be absorbed by the core, and the continuous combustion in the core will further consume the solid part of the wax. This dynamic balance maintains the characteristics of the continuous burning of the candle. The core can be cotton, hemp rope or other organic fibers, while wax is usually beeswax, awn wax or bitter orange wax.
