Abstract

An electronic device comprises a conductive device having a first end and a second end, a first element and a second element. The first element disposed on the first end of the conductive device generates a first temperature. The second element disposed around to the second end of the conductive device is switchable between a standby mode and an operation mode. The first temperature conducted from the first end to the second end shortens a warm-up time for the second element transferring from the standby mode to the operation mode.

Claims

1. An electronic device, comprising:

a conductive device comprising a first end and a second end;

a first element disposed on the first end of the conductive device, generating a first temperature; and

a second element disposed around to the second end of the conductive device, being switched from a standby mode to an operation mode, wherein the first temperature is transmitted from the first end of the conductive device to the second end of the conductive device to shorten a period from the standby mode to the operation mode.

2. The electronic device as claimed in claim 1, wherein the first element comprises a chip.

3. The electronic device as claimed in claim 1, wherein the second element comprises a light tube.

4. The electronic device as claimed in claim 1, wherein the second element comprises a cold-cathode fluorescent lamp.

5. The electronic device as claimed in claim 1, wherein the conductive device comprises a thermal conductive material.

6. The electronic device as claimed in claim 1 further comprises an intermediary disposed between the first element and the conductive device.

7. The electronic device as claimed in claim 6, wherein the intermediary comprises a cooling paste.

8. The electronic device as claimed in claim 6, wherein the intermediary comprises a dissipation fin.

9. The electronic device as claimed in claim 1, wherein the second end of the conductive device comprises a plurality of protrusions.

10. The electronic device as claimed in claim 9, wherein the protrusions are formed by sand blasting method.

11. The electronic device as claimed in claim 9, wherein the protrusions are formed by spot formation method.

12. The electronic device as claimed in claim 1 further comprising a circuit unit electronically connected to the first element and the second element.

13. The electronic device as claimed in claim 4, wherein the electronic device is a scanner.

14. The electronic device as claimed in claim 4, wherein the electronic device is a liquid crystal display.

15. The electronic device as claimed in claim 1, wherein the first end of the conductive device comprises a smooth surface.

16. The electronic device as claimed in claim 1, wherein the second element contacts the second end of the conductive device.
