Lighting device

A lighting device characterized in that it has a light irradiation portion comprised of light-emitting elements;

• a flexible shaft having a tip, and that is freely turnable and supports said light irradiation portion at the tip;
• extendible portions that support said flexible shaft, and provide a nested housing for each on of the extendible portions;
• a drive portion that drives the light irradiation portion;
• a power supply portion that supplies electric power to the drive portion;
• a case covering said drive portion at least;
• and
• a spring mechanism that allows said extendible portions and said flexible shaft to extend;
• and
• further characterized in that said spring mechanism allows said extendible portions to extend as said flexible shaft extends.

A lighting device, comprising:

• a light emitting diode;
• a flexible shaft having a tip and a base portion, said flexible shaft connected to the light emitting diode at the tip for supporting the light emitting diode;
• extendible portions connected to said base portion of said flexible shaft, said extendible portions being nested and linked to each other so as to be slidable in and out of each other and to support said flexible shaft when the flexible shaft is pulled out from the extendible portions, and said flexible shaft being freely turnable with respect to the extendible portions;
• a drive portion for driving said light emitting diode;
• a power supply portion for supplying electric power to the drive portion;
• and
• a case covering at least said drive portion.
