<P>PROBLEM TO BE SOLVED: To provide a medical illumination unit which comprises a rod-shaped body with a light source at a distant-end region and which can be made with a small-sized rod-shaped body. <P>SOLUTION: An LED chip 15 and a rod-shaped or tubular body 5 having a proximal end 11, a distal end 7, at least one distal hollow section 9 which begins before the distal end 7 and reaches to the distal end 7, and a supply leads section 12 which begins at the proximal end 11 and reaches to the distal hollow section 9. The LED chip 15 is arranged in the distal hollow section of the rod-shaped or tubular body 5 and is supplied with energy through the supply lead section 12. A luminescent converter material is arranged between the LED chip 15 and the distal end 7 of the rod-shaped or tubular body or at the distal end of the rod-shaped or tubular body 5, the converter properties of which in respect of the light emitted by the LED chip 15 are selected so that it may convert the light emitted by the LED chip 15 into light with a desired wavelength distribution. <P>COPYRIGHT: (C)2009,JPO&INPIT |
