Abstract

An optical indicating device unit includes at least one first housing, a mechanical interface, and a data interface. The at least one first housing includes at least one illumination device and/or at least one optical device, wherein the at least one illumination device and/or the at least one optical indicating device is configured to visually indicate information. The mechanical interface is configured to connect the at least one first housing to a second housing. The data interface is configured to transmit information to the at least one illumination device and/or the at least one optical indicating device.

First claim

The invention claimed is:

1. An optical indicating device unit, comprising:
a first housing including:
an illumination device configured to emit visible light; and
an optical device configured to digitally indicate information;

a mechanical interface configured to removably attach the first housing to a power tool housing of a first power tool; and
a data interface configured to receive information to be digitally indicated by the optical device, the information received from an external electronic unit of the first power tool,
wherein, when the at least one first housing is connected to the power tool housing by the mechanical interface, the illumination device is configured to illuminate a work region of the first power tool.

2. The optical indicating device unit as claimed in claim 1 , wherein the mechanical interface is configured to removably attach the first housing to the power tool housing of a plurality of different types of power tools.

3. The optical indicating device unit as claimed in claim 1 , wherein the illumination device includes at least one of a light source and a light conductor.

4. The optical indicating device unit as claimed in claim 3 , wherein the illumination device includes the light conductor, and wherein the light conductor is configured as a bar.

5. The optical indicating device unit as claimed in claim 3 , wherein the illumination device includes the light source, and wherein the light source includes at least one LED.

6. The optical indicating device unit as claimed in claim 1 , further comprising at least one second electronic unit located within the first housing and configured to perform at least one function.

7. A hand-held power tool, comprising:
a power tool housing;
an external electronic unit configured to provide an optical parameter; and
an optical indicating device unit including:
a first housing having:
an illumination device configured to emit visible light; and
an optical device configured to visually display information;

a mechanical interface configured to removably attach the first housing to the power tool housing; and
a data interface configured to receive the optical parameter from the external electronic unit and to supply the optical parameter to the optical device,
wherein, when the at least one first housing is connected to the power tool housing by the mechanical interface, the illumination device is configured to illuminate a work region of the hand-held power tool.

8. The hand-held power tool as claimed in claim 7 , wherein the hand-held power tool is configured as a random-orbit sander, an angle grinder, an orbital or delta sander, an oscillating multitool, or a router.
