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.
