LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

LED (Light Emitting Diode) is a semiconductor device that emits visible light when an electrical current passes through it. LEDs are among the most energy-efficient types of lighting available today; they produce less heat than traditional lighting and have a much longer life span. The R25-4.0-WHT (White) type of LED is a wide angle indicator type, and is typically used for circuit board indicators, arrays, light bars, and bar graphs.

The power supply required for the R25-4.0-WHT LED is typically between 4-12 volts dc, depending on the application. It is designed to emit a broad beam angle of 140 degrees, and it is capable of operating from -30 to +80 degrees Celsius. The rated output forward current for the R25-4.0-WHT LED is 40mA, and it has a typical luminous intensity of 1100mcd.

The working principle for the R25-4.0-WHT LED is very simple. When a sufficient voltage is applied to the LED, electrons in the semiconductor material become excited and start recombining with electron holes in the material, which generates energy in the form of light that is visible to the human eye. As the voltage is gradually increased, the light output of the LED will increase until the luminous intensity reaches its peak value.

The R25-4.0-WHT LED can be used in a variety of applications. It is ideal for circuit board indicator lights and light bars, and is also used in array-type displays, where multiple LEDs are arranged in a line or column to display information. With its wide beam angle, the R25-4.0-WHT LED is also well-suited for bar graph applications, where a single LED is used to produce a visual representation of a numerical value. It can also be used to produce visual cues in aircraft cockpits, dashboards, and other vehicle interface designs.

Overall, the R25-4.0-WHT LED is a versatile and economical choice for a wide variety of LED-based lighting applications. Its wide beam angle, luminous output, and operation temperature range make it an ideal choice for use in circuit board indicators, arrays, light bars, and bar graphs. This type of LED is also energy-efficient and has a long life span, making it a great choice when selecting LED lighting products.
