Device for correcting brightness roll-off at an end of a lamp

An apparatus comprising:

• an imaging camera including a frame part;
• a tubular lamp for providing light for said camera;
• and
• a device including (i) a first portion connected to an end of said lamp to reflect light from said lamp, and (ii) a second portion connected to said frame part of said camera to ground out electrostatic charge on an outer surface of said lamp, dissipate heat generated by said lamp, and gradually correct brightness roll-off at the end of said lamp to produce a uniform illumination of an imaging field of said camera.

A device for use with a lamp, said device comprising:

• a reflector portion for reflecting light from the lamp;
• and
• a connection portion extending from said reflector portion and for (i) connecting to an end of the lamp to enable said reflector portion to reflect light from the lamp, and (ii) connecting to a frame part to locate said reflector portion relative to the lamp such that electrostatic charge on an outer surface of the lamp is grounded out, heat generated by the lamp is dissipated, and light reflected from said reflector portion cooperates with light from the lamp to gradually correct brightness roll-off at the end of the lamp to produce a uniform brightness output at the end of the lamp;
• said connection portion including (i) a clip portion extending from said reflector portion and for connecting to the end of the lamp to enable said reflector portion to reflect light from the lamp, and (ii) a hook portion extending from said clip portion and for connecting to the frame part to locate said reflector portion relative to the lamp such that light reflected from said reflector portion cooperates with light from the lamp to produce the uniform brightness output at the end of the lamp.

An apparatus comprising:

• an imaging camera including a frame part, said camera being a contact image sensor type image camera;
• a tubular lamp for providing light for said camera;
• and
• a device including (i) a first portion connected to an end of said lamp to reflect light from said lamp, and (ii) a second portion connected to said frame part of said camera to ground out electrostatic charge on an outer surface of said lamp, dissipate heat generated by said lamp, and gradually correct brightness roll-off at the end of said lamp to produce a uniform illumination of an imaging field of said camera.
