According to the US Energy Information Administration, electricity generation (mostly for lighting applications) produces 37% of greenhouse gases. In China, the electricity consumption of lighting electricity is about 200 billion kWh, accounting for about 12% of the annual power generation. Implementing green lighting will reduce electricity consumption and thus reduce carbon emissions. Therefore, achieving green lighting is in line with the development of a low-carbon economy.
But in real life, LED lighting is obviously not enough. Due to high cost and high price, LED lighting is not good.
According to market conditions, 3W LED energy-saving lamps are priced at around 80 yuan. This price is equivalent to five or six times that of ordinary energy-saving lamps, and more than 10 times higher than incandescent lamps. Such prices are difficult to be accepted by ordinary families. At present, LED lighting is mainly used for public facilities, and the cost is not low. The price of a street lamp is 6,000-7,000 yuan, so it is generally supported by the state.
Sun Hua, an analyst at Huatai Securities, pointed out that the lighting market is the vision for the future development of LED applications. With the continuous improvement of technology, LEDs can achieve low-cost applications, but it takes three to five years.
