Member of Chinese academy of sciences, the famous optical and laser scientist professor LiuSongHao said on the 8th in the pearl river science lecture hall, the LED will soon replace incandescent lamp, lighting market. LiuSongHao think, the key technology on restriction may hinder the development of Chinese LED industry.
The LED will be popular
Compared with the commonly used incandescent lighting, LED has many advantages: first, it is a solid device, it has no filament and glass bulb, not afraid of vibration, not easily broken. Service life of up to fifty thousand hours. Secondly, LED lamp power consumption is only 60% of incandescent lamp, lamp, also do not contain mercury, lead and other hazardous substances, conducive to recycling. Third, the LED is dc drive, unlike incandescent lamp of ac drive there will be a high frequency of flashing, is conducive to protect his eyes. In addition, the LED need to voltage and current are smaller, suitable for mine and field use such a power shortage occasion.
According to LiuSongHao, now all countries in the increase of investment in the LED industry development, the U.S. department of energy in 2012 issued a “solid state lighting plan”, predicts that by 2030 55% of incandescent lamp and fluorescent lamp will be LED to replace, while South Korea’s goal is to become Asia’s biggest photoelectron producer, in 2015, 30% of the lighting instead replaced by LED lighting dimmable.
No.1 Lighting’s products have examples：3W e14 led candle bulb can repplace 25W incandescent bulb, 100 watt equivalent led 13w bulb and so on.
