Abstract
Lighting devices are taught for machine tools. The lighting devices may include one or more light emitters controlled by an electric circuit, which can be connected via one or more conductors to the inner circuit of an electric machine tool. The electric circuit may comprise at least one photometer and a controller that automatically controls the illumination level of the light emitters in response to the ambient light intensity detected by the photometer. The present invention also relates to machine tools comprising such lighting devices.
Claims35
A power tool comprising:
- a housing;
- a motor disposed within-the housing,
- a tool operably coupled to the motor,
- at least one light emitter adapted to light a work area around the tool,
- at least one light detector, wherein the at least one light emitter and the at least one light detector are disposed on the housing, and
- a controller adapted to receive signals from the at least one light detector and control the operation of the at least one light emitter in accordance with ambient light intensity detected by the at least one light detector.
A power tool comprising:
- a housing,
- a motor disposed within the housing,
- a tool operably connected to the motor,
- at least one light emitter adapted to light a work area around the tool,
- at least one light detector, wherein the at least one light emitter and the at least one light detector are disposed on the housing, and
- a controller adapted to receive signals from the at least one light detector and adjust light output of the at least one light emitter in inverse proportion to ambient light intensity detected by the light detector.
A power tool comprising:
- a housing having an outer casing,
- a motor disposed within the outer casing,
- a tool operably coupled to the motor,
- a light disposed on the outer casing in a position to light a work area around the tool,
- an ambient light detector disposed on the outer casing in a position to detect ambient light intensity, and
- a controller adapted to receive signals from the ambient light detector and adjust light output of the light in inverse proportion to the detected ambient light intensity.
A power tool comprising:
- a housing,
- a motor disposed within the housing,
- a tool operably driven by the motor and extending from the housing,
- a light mounted so as to illuminate a work area around the tool,
- an ambient light sensor mounted in optical communication with a source of ambient light, and
- a controller adjusting the illumination level of the light in response to signals received from the ambient light sensor.
A power tool comprising:
- a housing,
- a motor disposed within the housing,
- a motor operably driven by the rod and extending from the housing,
- a light mounted so as to illuminate a work area around the tool, and
- means for detecting ambient light around the work area and adjusting the illumination level of the light in response to the detected ambient light.
