Abstract
A laser level disposable on a reference surface includes a housing, a pendulum pivotably connected to the housing, a first laser diode disposed on the pendulum for emitting a first laser beam along a first path, and a lens disposed on the pendulum in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a line on the reference surface.
Claims (12)
1. A laser level disposable on a reference surface comprising:
a housing;
a first laser diode disposed in the housing for emitting a first laser beam along a first path;
a first lens disposed in the housing in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a first line on the reference surface; and a hanging assembly connected to the housing for mounting the laser level to the reference surface.
a housing;
a first laser diode disposed in the housing for emitting a first laser beam along a first path;
a first lens disposed in the housing in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a first line on the reference surface; and a hanging assembly connected to the housing for mounting the laser level to the reference surface.
2. The laser level of Claim 1, further comprising a second laser diode disposed in the housing for emitting a second laser beam along a second path, and a second lens disposed in the housing in the second path for converting the second laser beam into a second planar beam, the second planar beam forming a second line on the reference surface.
3. The laser level of Claim 2, wherein the first and second lines are substantially perpendicular.
4. The laser level of Claim 2, wherein the first and second lines are substantially parallel.
5. The laser level of Claim 1, further comprising a detector circuit disposed in the housing for detecting a feature behind or underneath the reference surface.
6. The laser level of Claim 5, wherein the detector circuit detects at least one of the group consisting of studs, wire and pipes.
7. The laser level of Claim 5, wherein the detector circuit controls the first laser diode so that, upon detecting the feature, the first laser diode lights up.
8. The laser level of Claim 5, wherein the detector circuit does not control the firs laser diode.
9. The laser level of Claim 1, wherein the first line is substantially horizontal and the reference surface is a substantially vertical wall.
10. The laser level of Claim 1, wherein the hanger assembly comprises a reference surface assembly that contacts the reference surface.
11. The laser level of Claim 10, further comprising a magnet disposed on one of the reference surface assembly and the housing, and a metal plate disposed on the other of the reference surface assembly and the housing.
12. The laser level of Claim 10, wherein the reference surface assembly comprises at least one of the group consisting of a pin and a mandrel.
