Title: Projecting system with color temperature adjusting function

Abstract: A projecting system includes a light source for emitting light, a color temperature detecting device for detecting a color temperature value of the light emitted from the light source, a control device for storing a plurality of selectable pre-determined color temperature values therein for a user to select a pre-determined color temperature value, an adjusting device, and a light-modulating device. The adjusting device is disposed in a light path associated with the light source. The control device is configured for controlling the adjusting device to adjust transmittance of the light transmitted therethrough so as to adjust the color temperature value of the light to the selected pre-determined color temperature value. The light-modulating device modulates the light to create an image.
