WP73EK/GDA

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

LEDs are a type of semiconductor light source that functions as a circuit board indicator （CBI）, array, light bar or bar graph. LED stands for Light Emitting Diode and is a type of semiconductor diode which emits light when a voltage is applied across it. LEDs are typically used to provide visual feedback from a circuit or from a device, such as a smartphone or laptop, and can come in various shapes, sizes and colors.

WP73EK/GDA Application Field and Working Principle

The WP73EK/GDA is a type of LED manufactured by Powerhouse Technologies. It is a dual color LED, meaning it has two colors of light when energized. The WP73EK/GDA has a green and red color that can be used together or separately to provide visual feedback. Its application field includes using it as a circuit board indicator, in arrays, light bars, bar graphs, and more.

The working principle behind the WP73EK/GDA is simple. When a voltage is applied to the LED, the electrons move from the layer of the diode that is connected to the positive voltage to the negative voltage. This process releases energy in the form of light, which is then visible. The intensity of the light depends on the voltage applied to the diode, and the color of the light is determined by the materials used in the semiconductor layers of the LED.

The WP73EK/GDA is capable of operating either in continuous, periodic or pulsed illumination. Continuous illumination is when the LED is continuously illuminated as long as the voltage is applied to the diode. Periodic illumination is when the LED is turned on and off to produce a flashing effect and pulsed illumination is when the LED is periodically pulsed on and off at a certain frequency.

The WP73EK/GDA LED is a great way to provide visual feedback from a circuit or device. It is a versatile LED and can be used in a variety of applications, and is a great choice for a circuit board indicator, an array, a light bar or bar graph.
