The future of led light bulbs

LED bulbs are made of semiconductors. Therefore, this light-emitting device can be made very small, only a few millimeters. It can be mounted on the wall or ceiling. If the lights are not turned on, their presence is almost imperceptible and can therefore be avoided. Ordinary incandescent lamps need to be equipped with a lampshade to prevent the trouble of light glare. In addition, these bulbs last a long time and hardly need to be replaced after installation. In the future, people may forget how to change the bulbs. He called on the UK government to invest more to ensure that the UK is at the forefront of this technology. In addition to being durable, these bulbs have great potential for energy savings. It has been calculated that if half of the light bulbs in the United States use light-emitting diode bulbs, 24 power stations could be shut down, billions of dollars would be saved, and carbon dioxide emissions would be drastically reduced. Therefore, the United States plans to use light-emitting diode bulbs for all traffic lights by 2006, so that each intersection can save $ 750 per year. Although this bulb has a lot of benefits, but to really enter the ordinary family is still facing two major obstacles. First, the price is too high, each bulb is priced at 30 pounds, while the ordinary incandescent bulb is only 35 pence, the gap is too large. Secondly, it is difficult to produce white bulbs suitable for home use.
