Abstract
A light detector which includes a housing having front and rear walls, a light receiving section disposed on the front wall, and displays disposed on the front and rear walls for showing the location of received light relative on the light receiving section. Also disclosed is a laser level including a motor, a shaft driven by the motor, a housing fixedly disposed on the shaft, the housing having a bore therein, a barrel pivotally connected to the housing, a laser diode module disposed within the barrel, and a screw disposed on the housing and contacting the barrel for adjusting the pivotal position of the barrel.
Claims17
A laser level comprising:
- a main housing;
- a laser housing pivotally attached to the main housing, the laser housing being pivotable about 90° relative to the main housing;
- a motor disposed in the laser housing;
- a shaft driven by the motor, the shaft having a longitudinal axis;
- and
- at least one diode disposed on the shaft for projecting a laser beam, wherein the laser beam is substantially perpendicular to the shaft.
A laser level comprising:
- a housing;
- a motor disposed in the housing;
- a shaft driven by the motor, the shaft having a longitudinal axis;
- at least one diode disposed on the shaft for projecting a laser beam, wherein the laser beam is substantially perpendicular to the shaft;
- and
- a first power tool battery pack electrically connected to the motor and removably attached to the housing.
A laser level comprising:
- a main housing;
- a motor disposed in the main housing;
- a shaft driven by the motor, the shaft having a longitudinal axis;
- a diode housing disposed on the shaft;
- and
- at least one diode disposed in the diode housing for projecting a laser beam, wherein the laser beam is substantially perpendicular to the shaft;
- wherein the main housing comprises an upper portion covering the diode housing.
A laser level comprising:
- a main housing;
- at least one diode disposed in the housing for projecting a laser beam, said beam being rotatable to denote a reference plane;
- and
- a protective bar flexibly connected to the main housing.
A laser level comprising:
- a main housing;
- at least one diode disposed in the housing for projecting a laser beam, said beam being rotatable to denote a reference plane;
- and
- a clamp assembly slidably attached to the main housing for clamping the laser level to an architectural feature.
A method for constructing a laser level comprising the steps of:
- providing a housing, a motor disposed in the housing, a shaft driven by the motor, the shaft having a longitudinal axis, at least one diode disposed on the shaft for projecting an elliptical laser beam with major and minor axes, wherein the laser beam is substantially perpendicular to the shaft;
- and
- aligning the at least one diode so that the major axis of the elliptical laser beam is substantially horizontal.
