看到这篇文章时，你是否也沐浴在人工光线下？对于多数人而言，人工照明是我们最熟悉的“朋友”。然而，经常处在人工照明下，尤其是夜幕降临而光线依旧明亮时，我们的昼夜节律容易受到干扰，进而影响情绪与行为。

Are you also bathed in artificial light when you read this article? For most people, artificial lighting is our most familiar "friend". However, if we are often exposed to artificial lighting, especially when the light is still bright at night, our circadian rhythm is easily disturbed, which in turn affects our emotions and behaviors.

This discovery has sounded the alarm for us, reminding us to be more cautious about the light environment and avoid letting light become an invisible "killer" of emotions. In order to create a healthier lighting environment and help people balance their circadian rhythms, a series of innovative technologies have emerged, among which Warm-dim and Tunable White dimming technologies are particularly eye-catching.

Warm-dim（调光暖化）

灯光变暗时色温会变暖

Color temperature gets warmer as lights dim

Warm-dim通过调节电流的方式改变LED灯珠的亮度和颜色温度。当电流较大时，LED灯珠发出的光线亮度较高，颜色温度较冷；而当电流较小时，LED灯珠发出的光线亮度较低，颜色温度较暖。

Warm-dim changes the brightness and color temperature of LED lamp beads by adjusting the current. When the current is large, the light emitted by the LED lamp beads is brighter and the color temperature is cooler; when the current is small, the light emitted by the LED lamp beads is lower and the color temperature is warmer.

Tunable White（可调白光）

色温变化的同时亮度不变

The color temperature changes while the brightness remains unchanged

Tunable White是一种让灯具能够灵活发出从暖白光到冷白光范围内光线的调光技术。它依赖于灯具内部配置的两类LED光源：一类是具有较低色温（2650K-3000K）的灯珠，呈现出较为温暖的色调；另一类则是具有较高色温（5000K-6000K）的灯珠，呈现出更为冷峻的色调。Tunable White通过调控各组灯珠中的电流流动，既改变灯具的亮度，又调整其色温，实现可调白光。

Tunable White is a dimming technology that allows lamps to flexibly emit light ranging from warm white to cool white. It relies on two types of LED light sources configured inside the lamp: one type is lamp beads with a lower color temperature (2650K-3000K), which presents a warmer tone; the other type is lamp beads with a higher color temperature (5000K-6000K), which presents a cooler tone. Tunable White changes the brightness of the lamp and adjusts its color temperature by regulating the flow of current in each group of lamp beads, achieving tunable white light.
