    摘要: A projector and a light source controlling method thereof are provided. The light source controlling method includes the following steps. The light source module is controlled to adjust a luminance of a projection light generated by a light source module starting from a low luminance. A power source voltage from an electronic device is detected to be equal to a threshold voltage or not. A power of the power source voltage is detected to be equal to a threshold power or not. When the power source voltage is equal to the threshold voltage and the power of the power source voltage is less than or equal to the threshold power, or when the power source voltage is greater than or equal to the threshold voltage and the power of the power source voltage is equal to the threshold power, the adjustment of the luminance of the projection light is stopped.
