If you're looking closely, you'll find them in everything from industrial control panels to rail train doors to aircraft instrument panels. Indicator lights are used, as the name suggests, to indicate the statuses of different components. An indicator might turn on when a machine is operating, for example, or flash if it's encountering a technical problem. The indicator lights on an elevator turn on to show what floor the car is on and when it's safe to exit. These are just two of the many applications of LED indicators. They are present in a wide variety of industries and are particularly important in those where safety is vital, such as industrial machinery and defense and aerospace applications. LED indicators are incredibly versatile.
Types of LED Indicators
Speaking of versatility, the number of LED indicator types is quite high. Here are some of the LED indicator lights that we offer at LEDtronics.
- Miniature base:
are straightforward, tiny lights that have a wide range of connection options. Base types include screws, wedges, slides, tubes, grooves, bayonets and more. They have a variety of color, shape and input voltage options, as well.
- Telephone slide base: LED
Telephone slide-base bulbs
have a wedge-shaped plastic tip that links up to the socket. Above it are two bars of metal that hold a relatively flat piece of glass that contains the wiring in place. Designs are differentiated based on how far the metal encases the glass. Telephone slide-base bulbs are primarily used in industrial applications.
- Relampable panel indicators:
Relampable indicators use lamp holders than can accept several various miniature lamps as needed. Changing colors or replacing lamps is possible with this kind of panel indicator. The configurations are vast and can include spade and screw terminals and cylindrical or domed lenses. They come in several color options and are even available as watertight fixtures.
- Snap/bolt panel indicators: A panel indicator with a snap or bolt configuration is more permanent and has a built-in lamp. These bulbs come in flat, top hat and dome lenses, as well as in a variety of colors. As the name would suggest, they either snap in or bolt on to the board.
- Machine status lamps: Machine indicators are omnidirectional with shock and vibration resistance. With substantial energy savings, low heat generation and a long lifespan, these indicators are excellent indicators for manufacturing and other industrial operations, relaying the status of a machine to anyone in the vicinity.
- SMD and discrete LEDs: In a surface-mounted device (SMD) LED, the LED chip is permanently fused to a printed circuit board (PCB). SMD LEDs use metallic contacts that solder onto the board instead of connecting it through wiring. Discrete LEDs are thin individual lights that leave configuration, installation and other options up to the user while emitting high power and offering a wide variety of colors.
- Intermediate base: Intermediate-based LED bulbs are a little closer to what you might see in a residential household. They are general-purpose and can be omnidirectional, dimmable or right-angled. Their uses are quite versatile, and you can find them in everything from cars and elevators to amusement park rides. The shape of an intermediate-based LED bulb can also vary widely as flame, chandelier, euro-candelabra, bent, bayonet and tube tips are all available.
- PCB LEDs: PCBs use LEDs in many different ways, and the lights need to be flexible to match this versatility. PCB LEDs come in right-angled arrays, vertical arrays, multi-level designs and more. Shapes include domes, cylinders, rectangles and modular lights for bar graph applications. They can be bi-colored or tri-colored.
- Appliance bulbs: Many appliances need specific bulbs to function appropriately. LED appliancebulbs are available in many shapes and power levels. You'll need to match the bulb appropriately to the specifications of the appliance.
- Exit sign and appliance: Exit sign bulbs are tube-shaped and usually T6 or T7 styles. They are used to illuminate signage, particularly bright red exit signs that are required around doorways.
- Beacon lamps: Beacon lamps offer full 360-degree illumination across an area. They contain multiple tiers that add height and power to the lights. They often provide light in a radial pattern, as in a lighthouse or the lights on a police vehicle.
- E12 candelabra: Candelabra bulbs fit a screw slightly smaller than a standard household bulb. They often have small bases and provide softer light. Cluster and tube designs are popular applications for candelabra bulbs, along with decorative lights.
Common Uses of LED Indicator Lights
LED indicator lights are increasingly common in a variety of industries where they are used to indicate the status of equipment and enhance safety. Whether an industrial facility needs reliable indicators, a military-grade vehicle requires long-lasting indicator lights or an elevator has to have responsive lighting on its panel, LEDs can hit the mark.
Just take a look at our list of markets to see how widespread these lights are. LED indicator lights are used in:
- Industrial controls
- Defense and aerospace
- Powerplants and utilities
- Transportation and railroad
- Elevators and vertical transportation
Benefits of LED Indicators
LED indicator bulbs offer several advantages over incandescent indicators. They are long-lasting and extremely durable due to their solid-state design and able to withstand a wide temperature range. They also come in multiple colors, shapes, sizes and input voltages, and you can even order custom LED indicators to meet your unique needs.
One of the primary reasons that businesses switch to LEDs is to save energy. LED lights are much more energy-efficient than incandescent bulbs. With the longer lifespan of LEDs, you can also enjoy minimal maintenance. Taking machines out of service to change a bulb is a time-consuming process that can be significantly reduced with the use of LEDs. Their energy efficiency and long life mean LEDs are environmentally friendly and can save you both money and time.
