Timers are an essential component of any exterior sign, as they help to control when the sign is illuminated and can help to reduce energy costs. In this post, we will explore the different types of timers available for exterior signs, including photocells, timer boxes, and phone apps, and discuss the importance of properly illuminating your sign at night.
Photocells:
Photocells, also known as light-dependent resistors (LDRs), are sensors that detect the presence of light and can be used to turn a sign on or off based on the ambient light level. They are often used in exterior signs because they can help to conserve energy by turning the sign off during the day when it is not needed and turning it back on at night when it is more visible.
There are two main types of photocells: passive and active. Passive photocells, also known as photoresistors, are made of semiconductor materials that change resistance when exposed to light. They are relatively simple and inexpensive, but they are also less accurate and may not work as well in low light conditions.
Active photocells, on the other hand, use a small battery or other power source to amplify the signal from the photoresistor, making them more accurate and reliable. They are also less affected by ambient light and can work in a wider range of lighting conditions. However, they are more expensive and require a power source, which can be a drawback for some applications.
Timer boxes:
Timer boxes are a type of external timer that can be used to control the illumination of an exterior sign. They typically consist of a small box with a timer and a relay, which is used to control the power to the sign. Timer boxes can be set to turn the sign on and off at specific times, or they can be programmed to follow a specific schedule.
Timer boxes are a good option for businesses that want to have more control over the lighting of their sign, as they allow you to set specific times for the sign to be illuminated. They are also easy to install and can be programmed with minimal technical expertise. However, they do require a power source and may not be as energy-efficient as other options.
Phone Apps:
In recent years, there have been a number of phone apps developed that allow you to control the lighting of your exterior sign from your smartphone. These apps typically use Bluetooth or Wi-Fi to communicate with a small device that is installed on the sign, allowing you to turn the sign on or off, change the brightness, or set a schedule remotely.
Phone apps can be a convenient option for businesses that want to be able to control their sign remotely, as they allow you to make changes on the fly without having to physically access the sign. They can also be more energy-efficient, as they allow you to turn the sign off when it is not needed and only turn it on when it is needed. However, they do require a smartphone and a reliable internet connection, which may not be practical for all businesses.
The importance of proper illumination:
Proper illumination is important for a number of reasons. First and foremost, it helps to make your sign more visible at night, which can be critical for attracting customers and ensuring that your business stands out. Proper illumination can also help to improve the overall appearance of your business, as a well-lit sign can convey a sense of professionalism and credibility.
In addition to these aesthetic benefits, proper illumination can also have practical benefits. For example, a well-lit sign can help to make your business more visible to customers, which can help to increase foot traffic and sales. It can also make your business more secure, as a well-lit sign can deter potential burglars and vandals.
Limiting electrical cost:
While proper illumination is important, it is also important to consider the electrical cost of operating your sign. Exterior signs can be a significant drain on your energy budget, especially if they are left on for extended periods of time. To help reduce energy costs, it is important to use energy-efficient lighting systems and to turn the sign off when it is not needed.
One way to do this is to use a timer, such as a photocell or timer box, to turn the sign off during the day when it is not needed and to turn it back on at night when it is more visible. This can help to reduce energy costs while still ensuring that your sign is properly illuminated when it is needed.
Another way to reduce energy costs is to use LED lighting, which is more energy-efficient than traditional incandescent bulbs. LED lighting can also last longer, which can help to reduce maintenance costs and downtime.
In conclusion, timers are an essential component of any exterior sign and can help to control when the sign is illuminated and reduce energy costs. There are several different types of timers available, including photocells, timer boxes, and phone apps, each of which has its own unique features and benefits. Proper illumination is important for attracting customers and improving the overall appearance of your business, but it is also important to consider the electrical cost of operating your sign and to use energy-efficient lighting systems and timers to help reduce energy costs.
