Patent ID: 8884530

Claim:
An intelligent illuminating device comprising: at least one lamp which is installable onto an object, the lamp having at least one light emitting unit and at least one light collecting unit defined therein; a light beam of the light emitting unit being projected out from the lamp toward a direction so as to form an illuminated region when the lamp is turned on, the light collecting unit corresponding to a targeted region outside the lamp; and each light collecting unit having a MCU and a PWM unit; wherein when the light collecting unit acquires the brightness value of the targeted region firstly, the brightness value is transformed into a signal and is transmitted to the MCU for calculation; thereby, the MCU compares the signal with a predetermined brightness value saved in the MCU, so that a difference brightness value between the signal and the predetermined brightness value is obtained; thereafter, the difference brightness value is further transmitted to the PWM unit via a command format, such that the light emitting unit is controlled by the PWM unit so as to project a light beam with a designated intensity which corresponds to said difference value; as a result, the brightness of the targeted region is optimized according to the brightness value of the targeted region; and wherein the light collecting unit further has a differential amplifying unit and an A/D converter unit; the differential amplifying unit acquires the brightness value of the targeted region so as to generate a signal, wherein the signal is amplified by the differential amplifying unit so as to be transmitted to the A/D converter unit; the format of the signal is converted by the A/D converter unit from an analog format to a digital format so as to be transmitted to the MCU for calculation.
