What is the price/performance ratio of LED lighting? What is the source of investment funds and the benefits of the transformation? This is the market's biggest concern about whether LED can be promoted on a large scale.
Take the LED street light of Qinshang Optoelectronics as an example. The cost of purchasing LED street lamps a year ago was 2,5003,000 yuan. At present, the price of street lamps has dropped to 1,500 yuan and 1,800 yuan. The return period for replacing 800,1200 yuan high-pressure sodium lamps has been reduced to 23 years. The LED street lamp saves 50 energy and has a life span of 9 years. During the period, the lamps do not need to be replaced. The cost performance of using new LEDs for streetlights is already very obvious.
Regarding the funds for the renovation and replacement of LED street lamps, Guangdong proposed in the “Implementation Plan for Promoting the Use of LED Lighting Products†that local finance will solve the funding sources for LED lighting renovation projects from the additional revenues of urban public utilities collected with electricity tariffs.
According to the data of the LED demonstration project in the past two years, the Guangdong Provincial Department of Science and Technology has calculated the economic benefits and energy saving and emission reduction effects of the LED street lamp renovation project.
According to the calculation of 2 million LED street lights, before the renovation, the annual electricity cost of street lamps reached 2 billion yuan, and the annual lamp replacement fee reached 500 million yuan, so that the total annual cost reached 2.5 billion yuan. After the renovation, the total annual savings will be 1.5 billion yuan, including a 50-saving electricity bill and a 500 million yuan replacement fee.
The total investment for the renovation of 2 million LED street lights is 4.89 billion yuan, plus a total loan interest rate of 6.1 billion yuan. During the 9-year life of LED street lights, a total of 13.5 billion yuan will be saved, and the local government will receive 7.4 billion yuan in energy-saving benefits.
In addition, it will save 10.8 billion kWh of electricity, equivalent to saving 3.79 million tons of standard coal, reducing sulfur dioxide emissions by 70,000 tons, reducing carbon dioxide emissions by 2.68 million tons, and reducing smoke and dust emissions by 70,000 tons.
It can be seen that the energy-saving benefits are extracted from the additional income of urban public utilities collected with electricity tariffs, which can fully pay for the investment of LED transformation, and can produce obvious economic benefits and energy-saving and emission reduction effects. Li Xinghua, director of the Science and Technology Department of Guangdong Province, said.
In the process of machining titanium alloy, the titanium alloy material itself has low modulus of elasticity, large elastic deformation, high cutting temperature, low thermal conductivity and high chemical activity at high temperature, which makes the sticky knife phenomenon serious, easily aggravating the tool wear and even breakage, which leads to the poor machinability of the titanium alloy. Therefore, machining titanium alloy requires proper cutting tools and good machining technology.
