Philips, which was born in the Netherlands in the 1970s, should be officially named rare earth tricolor compact fluorescent lamp. It is called energy-saving lamp because the light source only needs to consume the power consumption of ordinary incandescent lamp 1/5 to 1/4 on the premise of achieving the same light output, thus saving a lot of lighting power and expenses.

development status
Faced with good development opportunities, energy-saving lamps are also facing other troubles. 20 1 1 year, the national rare earth resource tax increased, which led to the soaring price of fluorescent powder for lamps. From March, 20 1 1 year, the phosphor experienced a sharp rise and fall in just half a year: firstly, it rose nine times in four months, from 300 yuan/kg to 3,000 yuan/kg.
The U-turn suddenly started in August, and by mid-September it had dropped to around 1300 yuan/kg. The price increase of fluorescent powder leads to the rising cost pressure of energy-saving lamp enterprises, which affects the operation of enterprises. If the industry can't smoothly transmit the rising costs, it will inevitably bring a new round of industry integration.
