239-3EVGW/D90(ES)

LED Indication -- Discrete is a family of LEDs that are visually recognizable as a discrete symbol by humans. They are typically used in industrial and commercial applications, such as traffic lights and components of devices. One example of a discrete LED is model number 239-3EVGW/D90(ES).

Application Field

The 239-3EVGW/D90(ES) LED is used in applications requiring a highly visible LED indicator. It can be used in a variety of industrial, transit, transportation and architecture based applications. The 239-3EVGW/D90(ES) has a wide viewing angle, low current consumption and is able to operate in temperatures between -40°C and +85°C. The LEDs can be combined to create a multi-colored indicators.

Working Principle

The 239-3EVGW/D90(ES) LED is powered by electricity. The electricity is converted into light energy by the LED itself. When no electricity is present, the LED is inactive and emits no light. When electricity is applied, the LED performs two functions: it emits light and provides electrical feedback. The emitted light, which can be green, red or amber, is visible to a person or machine. The electrical feedback, which is usually a voltage or current, is the indicator that indicates whether the LED is on or off. The current and voltage feedback is necessary for proper operation of the LED.

Conclusion

The 239-3EVGW/D90(ES) LED is a discrete LED designed for applications requiring an visible indicator to users. The LED is relatively energy efficient and can be used in a variety of industrial, architecture and transportation applications. The LED has a wide viewing angle and consumes a low amount of current. The 239-3EVGW/D90(ES) LED is made to both emit light and provide electrical feedback that indicates whether or not the LED is on.
