Automation lies at the core of much of our modern lives. However, it evolves at radical speeds. The simple concept, to build a machine to perform a task without human intervention, was the engine of the industrial revolution. Now that concept is the driving force behind robotics, self-driving vehicles, and a wide range of advanced technologies.

Most automated tasks are part of a closed-loop system. This system is designed so that the outputs are monitored and fed back to the controller. The controller changes its operation as needed. An example of a closed-loop system is a home thermostat, which monitors the air temperature. When the low set-point is reached, a contact closes in the thermostat, beginning a furnace lighting cycle. As the furnace runs, the room air temperature increases until the high set-point is reached. The contact opens and ends the furnace burn cycle. This is automation.

With electrical relays, it is possible to achieve a variety of automatic functions. A motor starter uses a relay to close a contact that sends electrical power to a motor. In addition, it closes a set of auxiliary contacts that keep the main relay closed. A control mechanism, such as a temperature input or a stop button, can be wired in series with the auxiliary contact. This allows for control of the motor. An expansion of relay logic is the programmable logic controller or PLC. Instead of mechanical relays, a PLC uses a set of input and output contacts connected to a computer controller. Software in the controller then dictates how the inputs and outputs interact. They additionally execute specific patterns of operations, based on programmed ladder logic.

The best lighting jobs are the ones that aren’t noticeable. Have you ever walked into a room and just felt warm, comfortable and at home? It was probably the light placement and selection in the room that gave you that unforgettable feeling. With the right tools and tips in mind, you can also have that within each room of your home.

In order to effectively use your lighting to enhance your home’s décor, you must first consider the function of your room, the natural light source and the mood you are looking to achieve in your room. With this in mind, you can transform the look and feel of your home!

Knowing the function of your room will allow you to select the appropriate type of lights and placement in the room. For instance, a reading room will have soft lights with intentionally placed reading lamps whereas a kitchen will be a lot brighter and will be equipped with a number of task lights – each room can have very different functions therefore using different light sources and equipment.

Once you have determined the function for each room, you should then discover the natural or ambient light provided throughout the day. In the morning, afternoon and evening, take the time to turn off all your lights and see where the natural light source may come from and how it can be appropriately supported. You may have a street lamp right outside your living room that still provides a considerable amount of light, meaning you may not need to add as much light as you would have assumed for the evenings.

Lastly, you should determine the specific mood you are looking to achieve for your room. Romantic, bright, warm, calm, energetic – there is a number of different effects you could be searching for based on your room and décor. In a living room, we generally recommend a central light to add to the ambient light in the room and then use small accent lights to highlight main decorative objects in your room like a painting, mirror or even a plant.

With the function, natural light source and mood of your room in mind, you can transform your home with simple adjustments to your lighting. For more tips on how to improve the lighting of your home or to have a professional help with the installation, contact Expert Electric at 604-681-8338.
