Abstract
A medical handle device having an illumination apparatus with at least one optical semiconductor component and a method for manufacturing such a hand-held device are displayed. It is proposed that in order to adapt the hand-held device to the specific requirements of a medical application such as uniformly high light emission, high mechanical resistance, sterilizability and electric safety, the illumination apparatus is provided with a base body, at least one blind hole arranged in the base body, a light-emitting window which is formed by the part of the base body extending from the bottom of the blind hole to the first end of the base body and is connected to a cover device which is connected to the base body and with which the blind hole forms a hermetically sealed interior, whereby the at least one optical semiconductor component is arranged in the hermetically sealed interior and the base body and the cover device are made of an electrically non-conducting material that can withstand sterilization. In some embodiments, at least one optical semiconductor component is encased in a transparent thermoplastic material.
