In all domestic exhibitions related to lighting, outdoor lighting lamps are generally in a relatively prominent position. Through the changes in the types and quantities of lamps exhibited, we can see the trend change of the whole outdoor lighting market. Taking the enterprises participating in the high-tech LED exhibition in 2013 as an example, the outdoor lighting products and technologies displayed by Sanma electric, Huaquan lighting, Ruiwei optoelectronics and other enterprises are selling with good heat dissipation effect, the price is based on high cost performance. The selling points of the products displayed by the enterprises all convey such information. In the current outdoor lighting market, the heat dissipation technology has become mature and the price of the products is gradually declining. In fact, with the increasing expenditure of urban public lighting year by year, coupled with the call for energy conservation and emission reduction, city managers are more willing to invest less, low maintenance costs save financial expenditure to build a livable urban environment. After pilot installation in many cities in the early stage, the advantages of energy saving, environmental protection and long service life of LED lighting lamps have been fully verified. Coupled with the maturity of LED lamp solutions, the price of LED lamps has also dropped to a level closer to that of traditional lamps. In this context, LED outdoor functional lighting enters the eyes of managers. In general, outdoor functional lighting includes street lamps, tunnel lamps and other functional lighting fixtures. Judging from the current quantity of outdoor functional lighting in mainland China, the quantity of street lamps and courtyard lamps is large, followed by high-pole lamps and high-power projection lamps, followed by tunnel lamps. Since street lamps and tunnel lamps are mostly affiliated to the public lighting field, they have developed earlier and faster. According to the high-tech LED Industry Research Institute (GLII) Statistics show that the market size of LED outdoor functional lighting in mainland China reached 8. 2 billion yuan in 2012, up 61 year on year. Among them, the market size of LED street lamps was 4. 2 billion yuan, up 43 year on year. Although the huge market demand has given the company a certain degree of money, it has also expanded the competitive pressure among peers. At present, the price competition in this industry is too fierce. In the bidding process, enterprises have been constantly pushing down prices. Even if enterprises win the bid, their profits will be much lower than in previous years. Zhao Yan, chief engineer of Sanma Electric, told Gao Gong LED that with the maturity of heat dissipation technology and the stimulation of rapid growth in market demand, the number of enterprises that share the cake of outdoor lighting among industries has gradually increased. In this phenomenon, Zhao Yan is worried about how to ensure the company's continued income, but also has his own ideas for the entire outdoor lighting industry. At the high-tech LED exhibition in 2013, Zhao Yan confidently told reporters about the company's development opportunities and goals in 2014. The increase in China's LED street lamp market is in high agreement with the government's fiscal expansion cycle. 2014 is the node of the government's new round of stimulus policy update, which should have a certain positive impact on the street lamp market in the second half of this year. Zhao Yan said.
