LED Street prospects also look at customer satisfaction

With the rapid development of LED technology, domestic high-power LED light efficiency has reached 80lm/W, LED lighting into urban road lighting become a reality. Since entering in 2009, LED street lighting has become the focus of the semiconductor lighting industry, more and more local governments recognize the energy saving characteristics of LED, local roads in the installation, use of the enthusiasm of LED street lights are rising.

As street management, LED street has made a breakthrough of the traditional street lamp, LED's long life, less maintenance, energy saving and other advantages to reduce the number of high-altitude operations, reducing the risk, from the color of light source on the road lighting effect, economy, life and other comprehensive look at the LED Street lamp has great advantages.

From the effect of color of light source on the road lighting, temperature of high pressure sodium (Tcp) is about 2100K, is a warm color, the color index (Ra) is only 23~25, color is low; and now use the color of the LED lamp has more than 5000K, the temperature is cool, good products, the Ra can reach 70~80. Good color. As the motor vehicle road, main road, yellow light lamp, to see about 90~160m distance to road conditions, slightly better effect than white light, especially for the fog, dusty air condition, sodium lamp has more advantages. For sidewalks, commercial pedestrian street, residential areas and other roads, the color rendering of LED is better than sodium lamp, the situation is clearer, more advantages.

From the economic analysis, comparison of high pressure sodium lamps, each about 1200~1500 yuan; the current LED street lights, according to the power of different sizes, the price difference is large, about 4000~8000 yuan. As far as the current situation is concerned, LED street lamp is obviously on the high side, but with the passage of time, the progress of technology, LED prices will gradually decline, energy efficiency will be further improved.

From the analysis and comparison of service life. LED lamp life should be based on the whole lamp life evaluation. High pressure sodium lamp, including light source, electrical accessories (mainly ballasts, triggers) and lamps, sodium lamp used for the average life expectancy of 6000 hours. LED street lamp life of up to 30 thousand hours, is the traditional street lamp 5 times.

Urban street lamp management as the representative of the user, more concerned about the maintenance of street lamps. The long life of LED street lamp makes the number of street lamp replacement will be greatly reduced. With the continuous improvement of the performance of the LED street lamp, it is very competitive in the trunk road and tunnel in the future.

As a new type of light source, LED street lamp needs to be improved in many aspects. In the process of using and popularizing, it is necessary to insist on serving the users and be responsible for the users. While the domestic LED enterprises in the new technology, new product promotion and strengthen efforts to dispel market potential customers for LED lamp products use concerns, will be the main stage LED enterprises under the government how to combine the demonstration project to promote the application of.

Ministry of science and technology to start the ten city ten million semiconductor lighting application engineering pilot, demonstration of LED street lamp market is also brewing for many years the development of positive. LED lamp cannot do without the prospect of market operation, "started ten city lights" semiconductor lighting project, the key technology breakthroughs in industrial transformation and upgrading, promote energy-saving emission reduction, the rapid development of China's semiconductor lighting applications to effectively guide the healthy expansion of semiconductor lighting market, stimulating consumer demand, promote industrial the development of core technology and innovation ability, quickly enhance the overall competitiveness of China's semiconductor lighting industry has a self-evident significance. Technical progress and market application are complementary and mutually reinforcing. Semiconductor lighting is bound to be adopted in the industry, transportation, municipal and other special lighting industry should be used to drive the first.
