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

Color temperature gets warmer as lights dim

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

The color temperature changes while the brightness remains unchanged

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.
