LIGHT EMITTING DIODE
In my last discussion I made use of Light emitting Diode as the Load of our counter I.C to display sequential lights. Light Emitting Diode also known for L.E.D for short has various applications and types. I intend to be straight and brief in this discussion as I wont be going into technical aspect of this for now since I want you to have a background idea of it first then subsequent discussion will contain vast detail of L.E.D
APPLICATIONS AND TYPES OF L.E.D
Light Emitting Diode is use in most electronics display today. Light Emitting Diode is a advance or modern form of display superseding cathode ray display as could be seen in old televisions and other forms of display such in old oscilloscope in laboratories.
- Light Emitting Diode is use in modern days Flat screen televisions. This technology is so unique and appealing such that the view of pictures is so realistic as if you are seeing the scene LIVE as it is been shot from the studio or movie scene. This is a large array of L.E.Ds in micro forms to form the pattern or matrix display needed to form images on screen.
- Light Emitting Diode is also use in Oscilloscope. Present day’s oscilloscope uses arrays of L.E.Ds to form waveforms or arrays of image as would a cathode ray tube.
- Light Emitting Diode is also use in Cars. Have you noticed or observed that present evolution of cars now uses L.E.Ds as Break-Lights, Side-Light and so on! This is so powers saving as L.E.D are not power consuming semiconductors.
- Light Emitting Diodes are also bee employed in Mobile Phones. Large amount of L.E.Ds are sandwiched or incorporated such that they form matrix of displays from top to bottom and can reproduce images as intended. They are so image appealing and unique.
ADVANTAGES OF LIGHT EMITTING DIODE
- They are less expensive (cheap) as compare to other forms of display such as cathode ray tube.
- They occupy less space. In electronics, space is a vital point to put into consideration when designing a device. Cathode ray tube occupies large space, L.E.Ds do not!
- Light Emitting Diode generates less or minute heat. Cathode ray tube generates heat due to its power consumption.
- Light Emitting Diode need less power or consumes less amount of power compared to cathode ray tube that requires start up current and high voltages in Thousands for its Line-Transformer.
- Light Emitting Diode is easily transported in large quantity and cheap in price as compare to cathode ray tube that would be heavy due to its weight and side, cost more to transport thereby making Light Emitting Diode easily accessible in less time and easily produce in large quantity in less time as compare to cathode ray tube. You will agree with me that the advent of technology has brought about comfort and research has further made it more worth living as compare to old days. I encourage us to be idea oriented and creative to contribute t the field of electronics and make impact.
