Abstract: The electric light source with reflector comprises a reflector (10) having a first and a second mirroring wall portion (12 resp. 22), which in axial sections are curved according to an arc (13 resp. 23) of a circle the centre of which lies before the plane  P  of the largest diameter ( d ), in an area extending predominantly at the other side of the axis, and behind plane  P  at the other side of the axis, resp. The reflector has a light emanating window (30) opposite to a lamp base (1). An electric light source (3) is disposed within the reflector (10) near plane  P  and the axis (11). The reflector (10) may be integrated with a lamp vessel (5) to give a reflector lamp.

Abstract: To determine glucose or other constituents of the human or animal body, a stabilized near-infrared radiation beam (D) containing two alternating wavelengths that have approximately equal extinction coefficients in the tissue, is directed onto the sample area (18), the transmitted signal (E) alternating component is zeroed by tuning one of the wavelengths, the extracellular-to-intracellular fluid ratio of the tissue is changed by exerting varying mechanical pressure on the tissue, or the ratio is allowed to change as a result of the natural pulsation. The alternating component of the transmitted beam power is measured in the changed fluid ratio state. The amplitude of the alternating-current (AC) signal given by the detector (19), is taken to represent glucose concentration or the difference from a preset reference concentration.
