Abstract:

The invention provides a light exposure apparatus containing a light exposure control device for curing light sensitive adhesives. The light exposure apparatus includes a) a light source; b) a light transmitter for transmitting light from the light source; and c) a light intensity controlling component between the light source and the light transmitter. The light intensity controlling component includes a light regulator having a planar face between the light source and the light transmitter. The light regulator has opaque members having a continuously tapered width, on the face of the light regulator. Each planar member is spaced from adjacent planar members by a light transparent segment having a tapered width, on the face of the light regulator. The light regulator is mounted such that a portion of the opaque members and portion of the substantially light transparent segments are adjustably positioned between the light source and the light transmitter.
