  • Patent number: 7802910
    Abstract: The invention provides a light guide exposure device comprising light emitting diodes arranged in a single array defining an array width and a flexible light guide having a proximal end and a distal end; the proximal end defining a proximal end diameter. The array is positioned in substantial alignment with the light guide proximal end to direct substantially all of the light from the array to the proximal end. There is no optical element between the light emitting diodes and the proximal end which optical element would decrease the intensity of light directed from the light emitting diodes to the proximal end. The array width is substantially equal to the proximal end diameter.
    Type: Grant

  • Patent number: 7671543
    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.
