Portable device for cervical inspection comprising groups of light-emitting diodes

A portable device for inspection of a portion of a body comprising:

• an elongated housing having a first end, a second end, and an optical axis that extends from the first end to the second end that allows viewing through the elongated housing;
• a magnification element that lies in the optical axis, wherein said magnification element is configured to provide a magnified view of a portion of a body to an observer observing the portion of the body with the portable device;
• a plurality of light-emitting diodes located at the second end and configured to illuminate the portion of the body, the plurality of light-emitting diodes comprising a first light-emitting diode group and a second light-emitting diode group, wherein
• the first light-emitting diode group emits light within a first wavelength range upon operation, wherein the light is continuous at least within 425-625 nm, and the second light-emitting diode group emits light within a second wavelength range upon operation, wherein
• the first wavelength range comprises a sub-range of wavelengths shorter than the second wavelength range,
• the second wavelength range comprises a second sub-range of wavelengths longer than the first wavelength range, and
• the first light-emitting diode group comprises three light-emitting diodes and the second light-emitting diode group comprises one light-emitting diode,
• wherein the three light-emitting diodes of the first light-emitting diode group have peak wavelengths of about 470 nm, 510 nm and 555 nm, respectively, and
• wherein the light-emitting diode of the second light-emitting diode group has a peak wavelength of about 660 nm;
• and
• a controller provided configured to control a luminous intensity of the second light-emitting diode group from a first intensity to a second intensity that is lower than the first intensity, to provide a preferred color rendering for visual examination of the portion of the body.
