High-power LED star is rising
Talking about high-power lighting, the high-power lighting fixtures currently used in the market are mainly high-pressure sodium lamps and metal halide lamps, but these lamps have high energy consumption, serious light decay, poor reliability and pollution to the environment (the lamps contain mercury); these lamps and lanterns It is also a thermal light source. Thermal light source refers to a light source excited by thermal energy. Most of its electrical energy is converted into thermal energy, with high thermal energy loss and low luminous efficiency. Another point is high-pressure sodium lamps and metal halide lamps. Alternating current light, stroboscopic serious.
High-power LEDs have huge advantages in energy saving, environmental protection, intelligent control and lifespan. They are an important promoter of achieving the national goal of "carbon peaking and carbon neutrality", and the market demand is also extremely urgent. In the past public perception, 100 watts is the maximum wattage of LED lamps. In the industry, traditional fluorescent glue LED packaging technology can only achieve 200W COB light sources. Traditional lamp bead array high-power LED lamps have large volume and weight. Heavy, difficult optical design, high cost, can not well meet the needs of the high-power lighting market, limiting its promotion and application in the market. Therefore, single light source high-power LED lamps are considered to be the best choice to truly replace traditional high-power lamps.
In 2015, Japan's Citizen Electronics exhibited the world's largest power 500W LED lighting products at the Hong Kong International Lighting Exhibition. There are still fluorescent powder glue packaging. The heat generated by high power cannot be dissipated efficiently. Practical problems.
On July 12, 2022, the Haixi Research Institute of the Chinese Academy of Sciences released two data, which are the comparison of Zhongke Xinyuan high-power LED lamps and high-power traditional lighting in terms of energy-saving life and investment.
According to the data released by the Chinese Academy of Sciences, taking a 6-meter-high industrial plant as an example, with an area of 3,600m2, 100 lights, 10 hours of electricity per day, 365 days in a year, 1.0 yuan per kilowatt-hour of electricity, 5 years it can save about 600,000 yuan in electricity, 150,000 yuan in maintenance costs, and reduce investment by 750,000 yuan in total.
According to the data released by the Chinese Academy of Sciences, taking a medium-sized offshore fishing boat with a length of 45 meters and a power of 400 kilowatts as an example, it requires 350pcs 2000W single-ended metal halide lamps to lure fish (700pcs 300W high-power LED floodlights), and uses diesel to generate electricity, the cost of electricity generation per kilowatt-hour is 1.60 yuan, and 30,000 hours can save 2.1 million yuan in hardware investment, 25.62 million yuan in electricity, and a total reduction in investment of 27.72 million yuan.
It can be seen from the above data that the initial investment of high-power LED lamps is relatively large, which is 3-5 times that of traditional lamps, but fortunately, the electricity consumed by them only accounts for 30% of traditional lamps, and hardware investment and maintenance costs are also more advantageous. In the long run, high-power LED lamps have more advantages than traditional high-power lighting.
