Abstract
A device for emitting electromagnetic radiation, in particular UV radiation, including at least one radiating unit that only emits radiation at visible wavelengths. The device further includes a unit for detecting a functional error of the radiating unit. In practice, the radiating unit is provided for emitting only UV radiation and/or IR radiation and is formed by a light diode. The detection unit is designed to continuously monitor the radiating unit for functional errors, and the device includes an open-loop and/or closed-loop control unit which is provided to automatically switch off the radiating unit and/or display the functional error, upon detection of the functional error by the detection unit.
Claims14
A lamp configured for an inspection of workpiece surfaces, comprising:
- at least one light-emitting diode configured to emit radiation only at invisible wavelengths and arranged to illuminate the workpiece surfaces with radiation only at invisible wavelengths;
- an emitter configured to emit visible light and arranged to illuminate the workpiece surfaces with visible light;
- and a detection unit for detecting a malfunction of the light-emitting diode, wherein the lamp is configured to automatically switch off the lamp or at least the light-emitting diode upon detection of the malfunction by the detection unit, wherein the light emitting diode and the emitter are arranged to emit radiation and light in a common direction.
A method for operating a lamp configured for an inspection of workpiece surfaces, which comprises at least one light-emitting diode configured to emit radiation only at invisible wavelengths and arranged to illuminate the workpiece surfaces only at invisible wavelengths and an emitter configured to emit visible light and arranged to illuminate the workpiece surfaces with visible light, the method comprising the steps of:
- directing the radiation from the light-emitting diode and the visible light from the emitter in a common direction at the workpiece surface;
- detecting malfunctions of the light-emitting diode using a detection unit;
- and automatically switching off the lamp or at least the light-emitting diode upon detection of a malfunction by the detection unit.
