Technical Field

Background
Color temperature is one unit of measure representing the inclusion of a color component in a light ray. Theoretically, blackbody temperature refers to the color that an absolute blackbody assumes after heating from absolute zero (-273 ℃). After being heated, the black body gradually turns from black to red, turns yellow and turns white, and finally emits blue light. When heated to a certain temperature, the spectral components contained in the light emitted by the black body are called the color temperature at this temperature, and the measurement unit is "K" (kelvin). If a light source emits light having the same spectral composition as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. If the color of the light emitted by the 100W bulb is the same as that of the absolute blackbody at 2527 ℃, the color temperature of the light emitted by the bulb is: (2527+273) k=2800k.
At present, more and more lamps on the market have a color temperature adjusting function, so that the color temperature of a user can be flexibly adjusted under different use scenes, and the damage to human eyes caused by wrong lamplight is reduced or even eliminated, for example, people usually need higher color temperature in daytime working and learning, the color temperature of the lamps is generally in the range of 5000-6000K, but the color temperature of the lamps is required not to exceed 4000K when working and learning at night. The mode that lamps and lanterns on the market carry out colour temperature adjustment is for adopting a set of high colour temperature and a set of luminous body combination of low colour temperature to adjust according to the mode of duty cycle, but the mixed light that this kind of mode adjusted back lamps and lanterns sent can't accomplish the colour temperature value the same or regional unanimity with the blackbody curve, can't realize the accurate regulation and control to the colour temperature, is difficult to satisfy the demand of user's healthy illumination.
