A Light Bar – Rectangle Series, also known as a Rectangular LED Light Bar or Rectangle LED Indicator, is an LED display component used for simple visual indication in electronic products, control panels and industrial equipment.
Unlike numeric displays, dot matrix displays or bar graph displays, a rectangular light bar is mainly used to provide a clear illuminated area for status, signal, mode or equipment condition indication. Its rectangular shape makes it suitable for panel designs where a wider or slimmer illuminated indicator is required.
Alfa Electronic Components supplies Rectangle Series LED Light Bars for industrial electronics, embedded systems, machine panels, electronic instruments, control panels and custom LED display assemblies. The range includes multiple rectangular body sizes for different PCB layouts, panel spaces and visibility requirements.
Rectangular LED Indicator Format
The rectangular format provides a clean and practical visual appearance on front panels and electronic equipment. It is useful where the design needs an illuminated strip-style indicator instead of a square indicator, numeric digit, arrow or text display.
This format can be used to indicate:
- Power status
- Machine status
- Signal condition
- Operating mode
- Warning indication
- Active/inactive function
- Equipment condition
- Control panel status
- Process status
- User interface indication
The final indication style depends on the selected model, LED color, circuit design and panel arrangement.
Available Rectangle Light Bar Sizes
The range includes seven body sizes:
- 5 × 10 × 8 mm
- 6 × 10 × 8 mm
- 7.5 × 14 × 8 mm
- 7 × 20 × 6.5 mm
- 10 × 20 × 6.5 mm
- 12 × 40 × 8 mm
- 20 × 40 × 9.5 mm
The smaller sizes such as 5 × 10 mm and 6 × 10 mm are suitable for compact PCB-mounted indicators and small equipment panels.
The medium sizes such as 7.5 × 14 mm, 7 × 20 mm and 10 × 20 mm are suitable for control panels, electronic instruments and embedded product interfaces.
The larger sizes such as 12 × 40 mm and 20 × 40 mm are useful where the indicator must be more visible or where a longer rectangular illuminated area is preferred.
Suitable for Status and Signal Indication
Rectangle LED Light Bars are commonly used where a simple visual indication is required without displaying numbers, letters or graphics. They are suitable for equipment status, signal condition, process indication, warning display and operator interface applications.
Their rectangular shape makes them useful for creating clear panel indicators, function indicators and compact signal lights in industrial and electronic products.
PCB Mount Indicator Component
These light bars are suitable for PCB-mounted applications. The selected model should be checked against the PCB layout, enclosure design, front-panel opening and required visible area.
Because light bars are often used in front-panel indication, buyers should confirm the body size, visible display area, pinout, electrical connection, LED color and latest approved technical drawing before PCB design or production.
Suitable for Industrial and Electronic Indication
Rectangle LED Light Bars are useful in industrial equipment, control panels, electronic instruments, power systems, machine interfaces, embedded products and custom LED indication panels.
They provide a simple, compact and effective visual indication method for applications where users need to identify status, signal or function quickly.
