Abstract

A soldering tool may include a tip portion and a tool body. The tool body may include a handle and the tip portion may be operably coupled to the tool body at a flange that separates the handle from the tip portion. The tip portion may include a tip that is heated to melt solder. The flange may include an end face and a light ring disposed at the end face. The light ring may be configured to direct light toward the tip.

First claim

That which is claimed:

1. A soldering tool comprising:
a tool body including a handle and a flange, wherein the flange comprises an end face and a light ring disposed at a portion of the end face;
a tip portion operably coupled to the tool body at the flange, wherein the flange separates the handle from the tip portion, the tip portion including a tip that is able to be heated to melt solder, wherein the light ring is configured to direct light toward the tip; and
processing circuitry configured to control a temperature of the tip and control an intensity of light output by the light ring based on the temperature of the tip to provide visual feedback information to a user regarding the temperature of the tip for melting solder.

2. The soldering tool of claim 1 , wherein the tip portion comprises a sleeve extending from the flange to the tip,
wherein the sleeve and the handle are coaxially aligned along a longitudinal axis of the tool body, and
wherein the light ring is coaxial with the longitudinal axis of the tool body.

3. The soldering tool of claim 2 , wherein the light ring extends around the sleeve and is spaced apart from the sleeve.

4. The soldering tool of claim 3 , wherein the sleeve comprises a collet configured to retain the tip without the use of tools.

5. The soldering tool of claim 1 , wherein the light ring comprises an annular lens and a plurality of light emitting diodes (LEDs), the plurality of LEDs being disposed at a circuit board provided proximate to the flange.

6. The soldering tool of claim 5 , wherein the annular lens comprises glass, polycarbonate or translucent material having a first diameter.

7. The soldering tool of claim 6 , wherein each LED of the plurality of LEDs is disposed to be equally spaced apart from each other and spaced apart from the longitudinal axis by a distance substantially equal to the first diameter.

8. The soldering tool of claim 7 , wherein the processing circuitry is further configured to control the intensity of the light output by the light ring by selectively powering some of the LEDs.

9. The soldering tool of claim 1 , wherein the processing circuitry comprises fault detection circuity;
wherein the circuitry is further configured to control the light output by the light ring based on a detection of a fault condition of the soldering tool by the fault detection circuitry.

10. The soldering tool of claim 1 , wherein the processing circuitry is further configured to control the light output by the light ring to changes colors to indicate changes in operational status of the soldering tool.

11. The soldering tool of claim 1 , wherein the processing circuitry is further configured to control the light output by the light ring to blink to indicate an operational status of the soldering tool.
