LED Bulbs
LED bulbs can be defined as semiconductor diodes which emit light in the particular directions. LED bulbs find frequent usage as indicator lights in various electronic devices, traffic lights, dashboards of cars and other domestic equipments. The composition of the semiconductor used determines the color of the light emitted by the LED bulbs. The nature of the produced light can be varied – infrared, visible or ultraviolet. However, the most difficult of all processes is generating a visible blue light is the most difficult process. The LED light bulbs are constructed by an identical alignment of the light emitting diodes in the shape of a light bulb. Thus the compact structure of the Led bulbs produces visible light that resembles daylight closely. Led bulbs are capable enough to replace the conventional light bulbs providing a better alternative to the compact fluorescent lamps and incandescent bulbs.
Lifespan of the LED bulbs depend directly on the ambient temperature of the LEDs. The durability of these bulbs can get reduced largely owing to the amount of heat produced by the LEDs. In such cases, after a couple of years the bulbs may show signs of age and provide only 50% of their original light output. However, undergoing researched designing and superior manufacturing processes the modern LED bulbs have far better lifespan than the earlier counterparts. And LED bulbs have always been a runaway winner against the traditional lighting methods. The lifespan of a LED light bulb is ten times that of a compact fluorescent lamp and hundred times of an incandescent bulb on average.
Most of the modern LED bulbs can operate within the range of 2-4 volts. The power consumption varies between 350mA and 1500mA depending on the purpose and design of the LEDs. Initially, as the LEDs could not be dimmed the effect on the power consumption was more. But now, with the latest LED manufacturing technology higher intensity of light can be achieved with less consumption of power. The incandescent bulbs waste a great deal of energy by generating heat. On the contrary, emission of heat by the LED bulbs being minimal, more energy is conserved. More energy efficient, LED bulbs consume 10% of the power consumed by standard light bulbs. These bulbs can withstand certain degrees of vibrations, shocks and temperature fluctuations. Unlike the incandescent bulbs, the light from LED bulbs does not flicker and can be availed in rich and vibrant colors.
