LED Indication – Discrete

Light emitting diodes (LEDs) are solid state lighting devices that convert electrical energy into visible light. They are efficient, small and reliable, making them popular for applications from indicators and displays to area lighting. A discrete LED typically consists of three main components: the LED chip, a housing, and a lens or reflector. The LT T673-Q1R2-25-Z is a typical example of a discrete LED, typically used as an indicator of power and signal states.

The LT T673-Q1R2-25-Z is a 5.6mm square LED formed of an LED chip (or die) in a transparent polycarbonate housing and integrated lens. The LED die is a red chip with a forward voltage of 1.8V to 2.2V and a continuous forward current rating of 25mA. The LED can be driven from any conventional constant current source in the range from 300µA to 25mA providing a light output that is proportional to the current.

The Application Field and Working Principle

The LT T673-Q1R2-25-Z LED is suitable for use in a wide range of applications such as signs, indicators, and consumer and industrial electronics. Its small size and low power consumption make it ideal for many small, low-power lighting applications. The LED is installed in a housing with a lens or reflector that controls the light and directs it in the desired direction. In many consumer electronics, such as mobile phones, the LED will be used as an indicator of power and signal states. The LED is powered by an external constant current source, typically connected in series with the LED chip. When power is applied, the resistor limits the current flowing through the diode, which results in the conversion of electrical energy into visible light. The light emitted by the LED is proportional to the current flowing through the diode.

In circuit applications such as mobile phones, the LED is usually connected to a logic gate, such as a digital IC or microprocessor, as part of a circuit that controls the illumination of the LED. The logic gate is configured in such a way that the LED will turn on or off when a digital signal changes from a low to a high state. This allows the LED to be used as an indicator of power and signal states.

The LT T673-Q1R2-25-Z LED is capable of producing a bright, eye-catching light in a very small package. It is an efficient, reliable, and low-cost solution for a variety of applications, from indicator lights to lighting for signs and displays.
