Abstract
An apparatus and method for measuring the aim of vehicle headlamps including measuring the light intensity of a light beam emitted by a vehicle headlamp to check the aim of the vehicle headlamp. The apparatus includes a linear photosensitive array having a plurality of individual photo sensors positioned between a plurality of baffles. The array is movably mounted to a frame whereby it can be positioned at predetermined locations to measure light beam intensity and correspondingly determine the beam pattern and aim point of a headlamp.

8. An apparatus for measuring the aim location of a vehicle headlamp comprising:
-
a frame, said frame including a cross member supported on opposite ends thereof by leg members;
a photosensitive array movably supported on said cross member, said array including a plurality of photo sensors disposed between a plurality of baffles arranged in a linear fashion and oriented in a direction generally transverse to said cross member;
a drive mechanism connected to said array, said drive mechanism operative to move said array on said cross member; and
a control unit, said control unit connected to said drive mechanism and to said array whereby said control unit positions said array and receives input from said photo sensors. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for measuring the aim location of a vehicle headlamp comprising the steps of:
-
providing a photosensitive array including a plurality of photo sensors and baffles arranged in a linear fashion, the photosensitive array movably supported on a frame;
positioning a vehicle at a predetermined position whereby the vehicle headlamps are a predetermined distance from the photosensitive array;
energizing said vehicle headlamps whereby said headlamps shine a light beam towards said photosensitive array;
using said photo sensors of said array to sense the light intensity of at least a portion of the light beam and generating a signal corresponding to the light intensity; and
using a control unit to record and display an output corresponding to the intensity. - View Dependent Claims (15, 16, 17)
