An adjustable light fixture including a base and a mounting member configured to movably connect a light source to the base. The mounting member is configured to rotate about a rotational axis that moves relative to the base. The adjustably light fixture can be implemented as an overhead light fixture by connecting the base to a ceiling. Also provided is a method adjusting an overhead light fixture including rotating a mounting member and translating the mounting member relative to a base.

A medical device assembly including a support member, a first arm rotatably connected to the support member at a first rotary axis, a second arm rotatably connected to the first arm at a second rotary axis, and a medical unit connected to an end of the second arm opposite the first arm. The first arm is prevented from rotating about the first rotary axis when the first arm and the second arm are substantially aligned. The first arm and/or the second arm can also be prevented from rotating to prevent the medical device assembly from abutting against an obstacle.

The present invention discloses a displayer screen hanging lamp, comprising a lamp body and a fixed bracket, wherein the lamp body comprises a lamp housing, a lens and a light source; the fixed bracket comprises an regulating frame, a support clamping mechanism and two clamping legs; the lamp body is connected and fixed with the regulating frame which is installed onto the support clamping mechanism, the forepart of the bottom of the support clamping mechanism is equipped with two clamping feet extending downward; the whole fixed bracket is clamped onto the displayer via the clamping feet and the clamping legs; the clamping feet clamp the front surface of the top of displayer and the clamping legs are rotated to change the clamping angle to clamp the back of displayer. The present invention can stably and conveniently install the whole lamping lamp onto any displayer of any specification and thickness through two clamping legs, two clamping pieces, two supporting arms and a regulating frame designed for interaction and it does not cover over the displayed content; the regulating frame is set with a clamping leg on its left and right sides respectively, not only solving the problem that the clamping legs interfere with the displayer bracket but also making the lamplight irradiate in front of the displayer. The lamp body is designed with a light-polarizing lens so that the lamplight does not irradiate towards the displayer to prevent the displayer from being not seen clearly due to lamplight reflection.
