Abstract: The disclosure provides a laser lighting system. The laser lighting system includes a microcontroller, a motor, a fluorescent color wheel and a detection circuit. The motor drives the fluorescent color wheel to rotate. The detection circuit is configured to detect a detected signal from the fluorescent color wheel. When a synchronous signal changes, the microcontroller compares the detected signal to the synchronous signal, in order to control the output current signal for driving the motor, and to decrease the phase variation between the detected signal and the synchronous signal until the phase difference between the detected signal and the synchronous signal maintain at a constant value.

Abstract: A projector comprises an environment detecting module and a processing module. The environment detecting module detects a predetermined environmental information at a first time and a real-time environmental information at a second time. The processing module is coupled to the environment detecting module, receives the predetermined environmental information and the real-time environmental information and executes a boot up method. The boot up method includes the steps of: storing and defining the predetermined environmental information as a comparison reference; and comparing the predetermined environmental information with the real-time environmental information, wherein when the predetermined environmental information and the real-time environmental information are substantially the same, a boot up program is executed, and when the predetermined environmental information and the real-time environmental information are substantially different, an authorization command request is outputted. A boot up method of a projector is also disclosed.
