Abstract

A power tool is arranged to operate in at least a first operating mode and a second operating mode. The power tool is operative to provide a first type of light signal from a light emitting device arranged to light up an object to be processed when the power tool is set in the first operating mode and to provide a second type of light signal when the power tool is set in the second operating mode.

First claim

The invention claimed is:

1. A power tool configured to operate in at least a first operating mode and a second operating mode, the power tool comprising:
a housing;
a detachable tool piece holder which is detachably attached to the housing;
a light emitting device arranged to emit light to an object to be processed; and
a processor which is configured to control the light emitting device to provide a first type of light signal when the power tool is set in the first operating mode and to provide a second type of light signal when the power tool is set in the second operating mode,
wherein the detachable tool piece holder comprises at least a first type of marking or second type of marking associated with the first type of light signal or second type of light signal.

2. The power tool according to claim 1 , wherein the power tool includes a handle, and the light emitting device is arranged in a lower part of the handle.

3. The power tool according to claim 1 , wherein the first type of light signal is a first color and the second type of light signal is a second color.

4. The power tool according to claim 3 , wherein the light emitting device is a light emitting diode (LED) configured to emit both the first color and the second color.

5. The power tool according to claim 1 , wherein the power tool is a cordless drill.

6. The power tool according to claim 1 , wherein the first operating mode is a first revolutions per minute (RPM) and the second operating mode is a second RPM.

7. A method in a power tool that is configured to operate in at least a first operating mode and a second operating mode, the power tool including a light emitting device that is arranged emit light to an object to be processed, the method comprising:
providing a first type of light signal from the light emitting device in the first operating mode of the power tool, and providing a second type of light signal from the light emitting device in the second operating mode of the power tool,
wherein the power tool comprises a detachable tool piece holder, and
wherein the detachable tool piece holder comprises at least a first type of marking or second type of marking associated with the first type of light signal or second type of light signal.

8. The method according to claim 7 , wherein the power tool includes a handle, and the light emitting device is arranged in a lower part of the handle.

9. The method according to claim 7 , wherein the first type of light signal is a first color and the second type of light signal is a second color.

10. The method according to claim 9 , wherein the light emitting device is a light emitting diode (LED) configured to emit both the first color and the second color.

11. The method according to claim 7 , wherein the power tool is a cordless drill.

12. The method according to claim 7 , wherein the first operating mode is a first revolutions per minute (RPM) and the second operating mode is a second RPM.

13. A non-transitory recording medium storing a computer program that is executable by a processor of a power tool that is configured to operate in at least a first operating mode and a second operating mode, the power tool including a light emitting device that is arranged emit light to an object to be processed, the power tool including the power tool a detachable tool piece holder, and the program being executable by the processor to control the power tool to perform functions comprising:
providing a first type of light signal from the light emitting device when the power tool is set in the first operating mode; and
providing a second type of light signal from the light emitting device when the power tool is set in the second operating mode,
wherein the detachable tool piece holder comprises at least a first type of marking or second type of marking associated with the first type of light signal or second type of light signal.

14. The non-transitory recording medium according to claim 13 , wherein the power tool includes a handle, and the light emitting device is arranged in a lower part of the handle.

15. The non-transitory recording medium according to claim 13 , wherein the first type of light signal is a first color and the second type of light signal is a second color.

16. The non-transitory recording medium according to claim 15 , wherein the light emitting device is a light emitting diode (LED) configured to emit both the first color and the second color.

17. The non-transitory recording medium according to claim 13 , wherein the power tool is a cordless drill.

18. The non-transitory recording medium according to claim 13 , wherein the first operating mode is a first revolutions per minute (RPM) and the second operating mode is a second RPM.
