A method is described for adjusting the brightness of at least one LED according to a changing supply voltage provided to the at least one LED includes acquiring a parameter which indicates the changing supply voltage; and providing, on the basis of the acquired parameter, a control voltage of the at least one LED for adjusting an LED current such that the at least one LED has a predefined relative brightness change over the predefined voltage range. A control unit and an LED lamp which implement the method described here are also discloses. Furthermore, an LED lighting apparatus and a medical diagnostic device having the LED lamp disclosed here are described.

Technique for adjusting the brightness of LED lamps

A power source device for diagnostic instruments is adapted for a connection of different types of illuminating devices and includes an active control unit for controlling an operating state of a power source in dependence on a type of a connected one of the illuminating devices.

Battery charging apparatus

A chargeable battery for medical diagnostic instruments includes a battery having an outer sheathing () in which an Li-ion cell () and a protective circuit are accommodated along with a charge/discharge module ().

Chargeable battery for medical diagnostic instruments

A handgrip for an electro-optical diagnostic-device set comprises a tubularly-shaped battery housing (10) for receiving variously-shaped energy sources (31, 33, 36, 38) therein to energize a lamp of an instrument head at a second end of the tubularly-shaped battery housing. There is a set of releasable end covers 40 for an opposite, first, end of the tubularly-shaped battery housing, with each of the end covers having a substantially identical cover attaching element (42) as that of the other end covers for mating with an opposite housing attaching element of the housing, but with each end cover being shaped differently from the other end covers, so as to accommodate an energy source different from energy sources accommodated by the other end covers.

Handgrip for an electro-optical diagnostic apparatus set

A camera apparatus for macrophotography is provided, having an attachment with a fixed lens, a translucent cap removably attached to the subject-side end of the attachment, and a contact disk or spacer ring attached to the subject-side of the cap and which defines a plane which includes the lens focus. The cap preferably is translucent, permitting flashtube light to be directed from the attachment to the target to be photographed.
