Abstract

The invention discloses a color temperature control method and system for an LED desk lamp. The method includes obtaining a face image of a user; identifying the mood of the user according to the faceimage; determining the mood index of the user through a mood-mood index comparison table according to the mood of the user; determining color temperature information through a mood index-color temperature library according to the mood index of the user; and controlling the color temperature of an LED desk lamp according to the color temperature. The system and method can perform camera shooting on the face of the user, identify the facial expression of the user and judge the mood of the user, so that the LED desk lamp can be controlled to generate white light with a color temperature matchingthe mood of the user.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a method and system for controlling the color temperature of an LED desk lamp. Background technique [0002] Color temperature is a physical quantity used to define the color of a light source in lighting optics, and is the most general indicator of the spectral quality of a light source. When the color temperature is less than 3300K (Kelvin), the light color is warm white (reddish white), giving users a warm and stable feeling; when the color temperature is between 3300-5000K, the light color is neutral white, giving users a refreshing feeling Feeling; when the color temperature is greater than 5000K, the light color is cool (white with bluish), giving users a cold feeling. Ordinary LED desk lamps have a fixed color temperature. There are also some LED desk lamps with several levels of color temperature, which can be manually adjusted by users. However, these LED desk lamps all have o...
