How Many Colors of LED Indicator Light are Available?
LED indicator is one of the most widely used small electronic devices, it belongs to a small light-emitting device, used in life for various household appliances, mechanical equipment, testing instruments and so on.
Mainly through the mature LED technology to convert electrical energy into visible light, so as to produce a bright and clear indication of light.
The role of LED indicators is irreplaceable, especially in terms of information interaction to convey information and equipment status indication. Whether it is in daily life in home appliances, computers, children’s toys or in industrial equipment, traffic signals, electronic instruments, LED indicators play a vital role.
How Many Colors of LED Indicator Lights Will be Available in 2023:
By 2023, the color variety of LED beads in the indicator industry is so rich that it can cover almost the entire visible spectrum.
The following are the common color types of LED beads:
| Color | Description |
|---|---|
| Red | One of the most common and frequently used LED colors, typically used for indications, warnings, and displays. |
| Green | Another common LED color, commonly used for indication, display, and lighting applications. |
| Blue | Used for a variety of applications such as lighting, decoration, indication, and display; a key component of RGB LEDs. |
| Yellow | Used for indication, warning, and signal light applications, known for its good visibility. |
| White | Available in various color temperatures (cool white, warm white) and widely used for lighting and display purposes. |
| Purple | A mixture of red and blue LEDs, commonly used for decorative, stage lighting, and special lighting effects. |
| Orange | A color between red and yellow, often used for indication, display, and decoration. |
| Cyan | A mixture of blue and green LEDs, commonly used for lighting, display, and decorative applications. |
| Pink | A mix of red and white LEDs, often used for decorative and stage lighting effects. |
It is already known that LED beads are particularly colorful, so based on FILN’s experience in the industry, we are able to produce bi-color and tri-color LED indicators, in addition to offering all types of single-color LED indicators in different colors.
Single-color LED indicator lights:
Single-color LED indicator lights come in a variety of common colors, including red, green, yellow, blue, white and purple. When LED indicator lights were not completely popular, FILN initially used neon lamps, but neon lamps have certain shortcomings, such as unstable life, resulting in the gradual elimination of the industry.
FILN monochrome LED signal light is not divided into positive and negative, so you only need to confirm that the line voltage and indicator voltage match, you can directly connect with the line to use.
Two-color indicator lights:
FILN provides two-color LED indicators usually have two types: common negative and common positive.
These dual-color LED indicator lights are usually wired at the end, regardless of whether it is common negative or common positive.
Of the three wires, one of them, the black wire, is the common wire, the red wire indicates a red light, and the green wire indicates a green light. For the common anode type, you can connect the positive to the black wire, the positive to the red wire if you need a red indicator, and the green to the green wire if you need a green indicator. Two-color LED indicator lights are commonly used in areas such as energy storage batteries and automation equipment.
Three-color LED indicator light:
Tri-color LED indicators are usually red-green-blue and red-green-yellow based.
For example, the Common Sun red, green and blue LED indicator usually has four wires, where the black wire is the common wire, the red wire indicates the red light, the green wire indicates the green light and the blue wire indicates the blue light. The color of the different wires is what represents the color of the LED light beads.
List the differences between the three types of indicator lights in the form of a table:
| LED Indicator light Types | Description |
|---|---|
|
Single-color |
– Available in common colors such as red, green, yellow, blue, white, and purple. |
| – FILN shifted from neon lamps to single-color LED indicators due to better stability and longer lifespan. | |
| – No polarity distinction; simply match the line voltage with the indicator voltage for direct connection. | |
|
Bi-color |
– FILN offers common negative and common positive types. |
| – Commonly used in energy storage batteries and automation equipment. | |
| – Common negative: Three wires, with black as the common wire, red for red light, and green for green light. | |
| – Common positive: Three wires, with black as the common wire, positive for red light, and green for green light. | |
| Tri-color Indicator Lights |
– Tri-color indicators are typically red-green-blue or red-green-yellow. |
| – Four wires for common types, with black as the common wire, and red, green, and blue/yellow representing the colors. |
Specific Functions of LED Indicator Lights:
LED indicators play a vital role in various applications, mainly by communicating different information and status through different colors, providing quick information interaction, easy observation and safety.
Understanding the colors and types of LED indicator lights can help us better understand and use these devices.
Among them, color plays a key role in LED indicator lights. Different colors of LED indicators are used to convey different information and status.
| Color | Meaning |
|---|---|
| Red | Warning, fault indication |
| Green | Normal operation, completion |
| Blue | Connection, activity |
| Yellow | Caution, attention needed |
| White | General illumination |
| Purple | Decorative, special lighting effects |
| Orange | Indication, display, decoration |
| Cyan | Lighting, display, decorative applications |
| Pink | Decorative, stage lighting effects |
LED indicator lights have become an indispensable element in modern life due to their widespread application in electronic devices and systems. These lights are crucial for conveying information and indicating various states. Understanding the background and uses of LED indicator lights, as well as the importance of color selection and usage, can greatly enhance user experience and work efficiency. Moreover, it drives continuous innovation and development in LED technology.
