The emergence of LED technology spurred a rapid transformation in the lighting industry. At first, preexisting solutions from the fields of device connection and control technology were used in the production and operation of LED lighting. Now, clearly defined interfaces between the light and the light source are a thing of the past. Today’s LED lighting is impressive with its variety of external shapes, versatility, and high proportion of electronic components.
Routing Cables Through the Lamp Housing
In principle, LED lighting consist of two parts: a light source (often called a light engine) and a controller. To support these components, cables with control signals and power supplies must be routed through the bulb housing. In the past, this routing was enabled by cable glands, which allowed engineers to route cables through a screw connection and then firmly connect them to the housing through a thread effect. Engineers then had to make additional connections inside of the light. This process has its own merit and is rarely questioned. However, newly developed alternative procedures can save a great deal of time.
Installation systems for various industrial devices and control technologies have been in use for many years. These systems manage power distribution in widely interconnected machines, systems, and buildings. Some of these product ranges also include panel feedthroughs that are perfectly suited to increasingly complex LED technology. Using these types of installation systems, engineers simply strip the cable, assign the wires, cut them flush with one another, and screw the cables toge
