Abstract

An illumination system comprises an illumination assembly, a human body'"'"'s signal detecting unit, a processing unit and an illumination direction adjustment unit. The illumination assembly projects an illumination light beam along an illumination direction; the human body'"'"'s signal detecting unit detects at least one human body'"'"'s signal released from at least one user to accordingly generate an intensity signal; the processing unit receives the intensity signal and transmits an illumination direction adjustment signal according to the intensity signal; and the illumination direction adjustment unit receives the illumination direction adjustment signal to automatically adjust the illumination direction.

Claims

1. An illumination system, comprising:

an illumination assembly projecting an illumination light beam along an illumination direction;

a human body'"'"'s signal detecting unit for detecting at least one human body'"'"'s signal released from at least one user to accordingly generate an intensity signal;

a processing unit electrically connected with the human body'"'"'s signal detecting unit, receiving the intensity signal, and transmitting an illumination direction adjustment signal according to the intensity signal; and

an illumination direction adjustment unit connected with the illumination assembly, electrically connected with the processing unit, and receiving the illumination direction adjustment signal to automatically adjust the illumination direction.

2. The illumination system as claimed in claim 1, wherein the human body'"'"'s signal is an infrared signal released from the user.

3. The illumination system as claimed in claim 2, wherein the human body'"'"'s signal detecting unit further comprises an infrared signal detecting member.

4. The illumination system as claimed in claim 1, wherein the human body'"'"'s signal is a sound signal released from the user.

5. The illumination system as claimed in claim 4, wherein the human body'"'"'s signal detecting unit further comprises a sound signal detecting member.

6. The illumination system as claimed in claim 1, wherein the illumination direction adjustment unit further comprises a driving motor connected to the illumination assembly, so as to turn the illumination assembly in accordance with the illumination direction adjustment signal to adjust the illumination direction.

7. The illumination system as claimed in claim 6, wherein the illumination direction adjustment unit further comprises a driving circuit electrically connected with the processing unit and the driving motor, so as to drive the driving motor.

8. The illumination system as claimed in claim 1, further comprising an illumination direction sensing unit electrically connected with the illumination assembly and the processing unit, so as to sense the illumination direction.

9. The illumination system as claimed in claim 8, wherein the illumination direction sensing unit further comprises a gyroscope, so as to sense an azimuth angle of the illumination direction.

10. The illumination system as claimed in claim 8, wherein the illumination direction sensing unit further comprises a gravity sensing member, so as to sense an elevation angle of the illumination direction.

11. The illumination system as claimed in claim 1, further comprising a memory unit electrically connected with the processing unit.

12. The illumination system as claimed in claim 11, wherein the memory unit further comprises an illumination direction calculation program, so as to calculate a angular coordinate that the illumination direction needs to be adjusted in accordance with the intensity signal.

13. The illumination system as claimed in claim 11, wherein the memory unit further comprises a sensitivity memory region for storing a detecting sensitivity of the human body'"'"'s signal detecting unit.

14. The illumination system as claimed in claim 11, wherein the memory unit further comprises an illumination direction memory region for storing the angular coordinate of the illumination direction.
