09 Taiwan's key LED street lighting enterprise strategic layout research

In 2009, it can be said that the LED streetlight market has accelerated its expansion. At present, in addition to the start of the LED streetlights in various cities in mainland China, Taiwan has released many LED streetlights in addition to the domestic budget, including the United States and Europe. LED street lights have also been tried in a relatively large-scale way. These actions are intended to replace traditional street lights and to try to produce regional road lighting applications with renewable energy such as solar energy and wind power in areas where electricity is scarce.
Since the LED street lighting standard (CNS15233) in Taiwan was officially adopted in the second half of 2008, most of the LED specification data published by the current manufacturers are the initial values ​​measured by the Taiwan Industrial Technology Research Institute (IT RI). It is estimated that after Q2 2009, the list of LED street lights that have officially passed the CNS15233 road standard will be announced one after another. The maturity of the market and the willingness and progress of local governments will increase.
Viewpoints of current LED street lamp manufacturers, the initial value of luminous efficiency can pass the Class-3 level of the CNS15233 road standard (initial value ↑45Lm/W), and some manufacturers with better luminous efficiency can even reach Class-2 (initial) The value is L60Lm/W). However, most of the light sources used are LED components of foreign manufacturers (such as Osram, Cree, Nichia, etc.) to meet current standards.
Under the circumstance that trade protectionism is likely to recover, it can be foreseen that in many government engineering projects, if the conditions limit LED streetlight components and components need domestic self-made, it will have a major test for existing street lamp manufacturers. In addition, the current street lamp bidding competition is fierce. If it needs to stand out in the bidding case, most of them need low price bidding. However, street lamp manufacturers that need to comply with specifications and adopt foreign LED components, LED components account for 40-50% of the total cost of LED Lamp heads, manufacturers are difficult to profit. Therefore, unless the price of foreign LED components drops significantly, it is only possible to meet the LED streetlight standards by relying on domestic manufacturers to improve product specifications.
Although China and Taiwan both use public works to support local LED-related businesses at this stage, the street lamp market has a lot of imagination, but it is not a long-term solution to induce manufacturers to lose money to bid for low prices. While the government has released orders, it should also consider how to foster domestic LED-related operators to improve product specifications and technological autonomy, which is the benign development of the industry.
