Overview of Andon Lights

If you’re looking for an efficient and easy way to improve your manufacturing process, consider using andon lights.

They are signal lights that notify workers of a problem or issue in the production line. Unfortunately, many different types and brands of andon lights are available on the market, so deciding which is right for your business can be challenging.

This blog post will provide an overview of the different types of andon lights available and a list of vendors that sell these products. We’ll also discuss the benefits of using them in your manufacturing process and outline tips for choosing the right product for your needs.

What are andon lights, and what do they do?

Andon lights are a type of signal light that notify workers when there are problems with the production line.

For example, these can indicate when machines need to be stopped or restarted because they’re experiencing issues like quality-related problems and safety hazards in their tasks – which is vital for lean manufacturing strategies, so everything runs smoothly without any hiccups!

The different types of andon lights

The different types of Andon Lights

Standard andon lights

Standard andon lights are the most basic type of signal light. These lights typically contain a red, yellow, and green light controlled by a switch.

The red light indicates a problem or issue that needs to be addressed, the yellow light indicates when the machine needs to be stopped or restarted, and the green light indicates when the machine is running smoothly.

Banner andon lights

These are signal light types that are typically used in assembly lines. These lights consist of a banner that is hung from the ceiling and has a light that is controlled by a switch.

The banner andon lights can indicate when a machine needs to be stopped or restarted, when there is an issue with the quality of the product, or when there is a safety hazard.

In many cases, the banner andon lights will also have an audible alarm that will sound when the light is activated.

That can help notify workers in the area that an issue needs to be addressed. These are an essential part of any assembly line, and they can help improve the line’s efficiency while also ensuring the safety of the workers.

Stack lights andon lights

These are signal light types that are typically used in assembly lines. These lights consist of a stack of three lights controlled by a switch. The switch controls the sequence of the lights, and each light represents a different stage in the assembly process.

Stack lights andon lights are essential to many assembly lines, as they help keep the line moving smoothly and safely.

Sound andon lights

The sound of an alarm can be a jarring experience, especially when accompanied by flashing lights. But for workers in a factory or other industrial setting, these signal lights are essential for their job.

Sound andon lights are designed to attract attention and alert workers to a problem or issue in the production line. Sometimes, the alarm may be sounded by a human operator, but it is often automated. These alarms can be lifesavers, helping to prevent accidents and mistakes.

In a busy factory setting, they can also help keep the work flowing smoothly by drawing attention to potential problems before they cause a stoppage in production.

LED andon lights

One of the key benefits of LED andon lights is their energy efficiency. These lights use less power than traditional incandescent bulbs, which can help to reduce energy costs.

In addition, LED lights have a longer lifespan than traditional bulbs, meaning they need to be replaced less often. As a result, these can provide both financial and environmental benefits.

Remote control andon lights

These offer the same benefits as traditional andon lights, but with the added convenience of being able to be activated from a distance. This can be useful when it is not possible or practical to physically pull the Andon cord, such as when an emergency arises outside of regular working hours.

Remote control andon lights can also be programmed to activate in certain situations, such as when a fire alarm is triggered automatically. So whether you are looking for a way to improve communication in your factory or want to add extra safety to your workplace, these may be the perfect solution.

USB andon lights

These are a type of signal lights that a USB port can power.

These lights are commonly used in manufacturing facilities to indicate the status of a process or machine. For example, a green light may indicate that a machine is running smoothly, while a red light may show an issue that needs to be addressed.

They offer several advantages over traditional signal lights. They are less expensive to operate and maintain and can be easily added to existing machines and equipment. In addition, USB lights are more versatile than traditional signal lights, making them an ideal solution for various applications.

Andon tower light

Tower lights are a type of signal light typically used in assembly lines. These lights consist of a tall tower with a light on top controlled by a switch.

The purpose of the light is to signal when an issue occurs so that it can be resolved quickly. For example, the light will indicate an issue if a part is missing from the assembly line. In this way, tower lights help to ensure that problems are quickly identified and addressed, allowing the assembly line to run smoothly.

Many different types of tower lights are available on the market, each with its own features. However, all tower lights share the same primary function: to help keep the assembly line running smoothly.
