Description

technical field

[0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to an LED device and a method for controlling light emission of the LED device. Background technique

[0002] Color temperature is a physical quantity used to define the color of a light source in lighting optics, that is, when a black body is heated to a temperature and the color of the light emitted by it is the same as the color of the light emitted by a light source, the heating temperature of the black body is called. It is the color temperature of the light source, referred to as color temperature, and its unit is expressed in "K" (Kelvin temperature unit).

[0003] In the prior art, the environment in which it is located is mainly provided with light with the color temperature of the environment through dual-color temperature LEDs. For example, the dual-color temperature LED is used to provide the image that needs to be collected with flashes wi...
