LED Indication - Discrete

LED Indication - Discrete denotes the use of LED lights to indicate various states or levels of an operation. LED stands for "Light Emitting Diode" and these tiny diodes can be used to indicate states or presence of an energy source, such as electricity or gas pressure. LED indicators are small, low powered, and can be operated for long periods of time with minimal power consumption.LED lamps vary in size, shape and color, and different numbers of LEDs may be used to create the desired indication. Discrete LEDs may be used to indicate different states or levels, including on/off indication, indication of multiple levels, or warning states. Discrete LED indication is often used in system control panels, HVAC (heating, ventilation, and air conditioning) units, household appliances, and other applications.Discrete LED indication is usually extremely simple to implement, as the circuit needed to drive the LED is usually very straightforward. LEDs can often be powered by a single DC voltage supply, such as 3 volts or 12 volts. Low current limiting resistors can be used, and all LEDs will require a power supply of some kind. When multiple LEDs are used, all LEDs must be provided with the same voltage and current level, or some will appear dimmer than others.LED indicators may also be mounted on specialized connectors that include a plastic base, which can be snapped into place on the circuit board. This type of connector allows the LEDs to be easily replaced if they burn out or if they need to be upgraded. Many types of discrete LED connectors are available from various manufacturers, making them easy to find and relatively inexpensive.LEDs can also be used to indicate temperature. Thermochromic LEDs are designed to change color depending on the temperature of the environment. These LEDs can be used in industrial applications such as temperature monitoring, or in consumer electronics such as coffee makers and air conditioners. Thermochromic LEDs can also be used in medical applications, and are becoming increasingly common in home medical diagnostic equipment.Discrete LED indication is used in automotive applications as well. Many cars have a dashboard display that includes LED warning lights to indicate when something has gone wrong. For example, some General Motors vehicles have a low fuel indicator light, which will come on when the fuel tank is low and needs to be refilled.Discrete LED indication is a reliable, cost effective and easy to implement way to indicate states or levels of an operation. LEDs can be used for a wide range of applications, from simple on/off indication to sophisticated thermochromic devices. By combining LEDs with specialized connectors and computer-controlled digital circuits, designers can build powerful and versatile control panels and system displays.
