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

As the name suggests, 5894S5;5;5;5 (LEDs) are small bead-like devices that emit intense, colored light when energized. In essence, LEDs are a type of semiconductor, possessing a unilateral conductive characteristic and have a very low forward voltage requirement. This makes them very attractive as indicators, displays and other types of illumination.

To better understand the working of LEDs and their vast application field, an understanding of their structural composition is required. An LED consists of a semiconductor chip, a metal base for electrical connections and a plastic shell for protection. This chip is a mix of an Anode and a Cathode, with the anode being the positive charge and the cathode being the negative charge.

When current passes through the LED, the electrons released by the anode jump to the cathode and release the energy stored on the semiconductor chip. This energy is then released in the form of radiation and light, which gives the LED its characteristic color. The amount of energy released also defines the intensity or brightness of the light emitted.

LEDs are extensively used as indicators for various electronic circuits files, as displays for control systems, as indicators for audio and video devices, as well as for general lighting purposes. They are available in multiple colors such as red, yellow, green, and blue. In addition to their low current requirements, their power efficiency, durability, and long lifespan make them the most preferred source of illumination.

LEDs are often found embedded in circuit boards, fixed on arrays, or in the form of light bars and bar graphs. In circuit boards, LEDs provide essential signals in addition to being used as indicators, status lamps and decorative displays. Array type LEDs are found as indicators in industrial and other heavy duty applications while light bars and bar graphs provide visual displays and outputs in control systems.

Apart from the practical application ranging from automotive to medical fields, LEDs have also become popular in art projects. Their low cost, wide array of colors and ease of assembly have made them the medium of choice for creative expression in the world of mixed media sculpture, light installations and kinetic art. As technology advances, LEDs offer more promise in the fields of customized lighting, digital displays and wireless control systems.

It is believed that the future of lighting will be pioneered by LED technology as it has proven to be reliable, efficient and cost-effective. Their widespread application show no sign of waning, with LED products continuing to populate the market in many ways. From this, it is evident that LEDs are here to stay and will continue to play an important role in lighting for many years to come.
