The preset color temperature of the white light emitted by the fourth light source is 2700K, and the preset color temperature of the white light emitted by the fifth light source is 7000K.
When the required color temperature is less than 2700K, the fourth light source and the first light source are conducted, and the luminous flux is correspondingly adjusted;
when the required color temperature is 2700K, only the fourth light source is conducted, and the luminous flux is correspondingly adjusted;
when the required color temperature is between 2700K and 7000K, the main control circuit 103 simultaneously switches on the fourth light source and the fifth light source, and correspondingly adjusts the luminous flux of the fourth light source and the fifth light source according to the required value of the color temperature;
when the required color temperature is 7000K, only the fifth light source is turned on, and the luminous flux is adjusted accordingly.
