Claims17
A searchlight device comprising:
- a housing including a first end;
- a window in the first end of said housing;
- a lamp disposed within said housing so as to emit light through said window;
- a shaft;
- a positioning assembly secured within said housing, said positioning assembly including:
- a first motor operable to rotate said housing in a first plane with respect to said shaft, and a second motor operable to pivot said housing in a second plane with respect to said shaft;
- a first gear secured with respect to said shaft, and a second gear rotatable by said first motor, wherein operation of said first motor causes said first and second gears to engage and rotate said assembly about said shaft in said first plane;
- and
- a washer including a plurality of tabs positioned so as to limit said rotation of said assembly by said first motor to a predetermined rotational angle.
