BRIEF

[Neptune]is a bionic joint magnetic suction tool lamp. A 3-UU bionic joint is set between the LED lamp head and the body, so that the lamp head can be twisted to different directions to achieve more accurate focused lighting. It is named after Neptune, the God of the Sea from roman mythology, because the 3-UU structure consists of three twisting and rotating rocker arms, similar to the trident of the Sea God, winding upward. The shape of water ripples is also used in the multisection of the lamp cover to echo.

PURPOSE

The original intention of this project is that the main lighting of the room is usually a top light source when I’m doing the assembly or welding of small parts in manual work. In this way, the close head and hands will produce shadows and make the operation difficult to see clearly. Therefore, a high brightness, focusing light source that can be adjusted flexibly is really needed. A gimbal structure was added to the tool light to adjust the lighting direction. And a magnetic suction module will be added at the bottom, so that it can move flexibly on the metal surfaces.

PC-PROTOTYPING

Here are some details of the modeling process. The first is the 3-UU joint, one single rocker arm needs to have two angles, to avoid collision interference, and in one of the rocker arms I notched the word NEPTUNE. LED uses a 7W COB lamp board, which has a large heat output, so it is provided with aluminum radiator fin below, and plenty of heat dissipation holes are opened on the lamp body. The whole structure is telescopic, and the bottom is equipped with NdFeB magnet ring, which can be attached to the metal surfaces. After pulling out the lamp cap, it can be used as a multi-pointing tool lamp. And after pushing back the lamp cap, there is NdFeB magnet pairs inside to fix it. The telescopic structure is also an original design. The sliding structure consists of a 3D-printed base and a screw-assembled slider attached to the base with a 3-UU joint and lamp holder. Each of the sliders consists of a cylindrical-thin-head-flat screw and a cylindrical-nut attached to it. The smooth cylindrical-nut and the 3D-printed shell form a sliding group together. The switch is selected as a micro-switch, which is set at the bottom of the lamp body. When the lamp cap is withdrawn, the base will trigger the switch to close, and the LED can be lit by pulling out.
