Research on the strategic layout of Taiwan key LED street lamps in 09 years

2009 is LED street market to accelerate the expansion of the year, with the exception of China, LED of the city street lighting case batch started, Taiwan area because of the expansion of domestic demand has also released many budget LED lamp case, including the United States, Europe, also to compare the scale of the way to start the pilot LED lamps, these actions are in order to replace the traditional lamp, and try to collocation such as solar energy and wind energy renewable energy in power shortage area to produce regional road lighting applications.

Due to Taiwan's LED street lighting standard (CNS15233) is in the second half of 2008 formally adopted, so the standard LED data released by the current manufacturers mostly Taiwan ITRI (ITRI) initial measured value. Estimated in 2009 after Q2, the official adoption of the CNS15233 road standard LED street lamp list will be announced, when the market maturity, as well as the willingness and progress of local governments will improve.

viewpoint

Observation of LED lamp manufacturers now, the initial luminous efficiency at present value through the CNS15233 road standard Class-3 level (initial value = 45Lm/W), some manufacturers and even better luminous efficiency can reach Class-2 (initial value = 60Lm/W). However, the use of the light source (lightsource) mostly for foreign manufacturers (such as OSRAM, CREE, Nichia, etc.) LED components to achieve the current standards.

While trade protectionism likely recovery worries, can foresee the future in many government contracts, if the LED lamp assembly and components are in need of domestic made limited conditions, will produce a major test for the existing street vendors. In addition, the current competition is fierce street signs, if you need to stand out in the case, most of the need to grab cheap bid. However, the need to meet the specifications and the use of foreign LED components of the street lamp manufacturers, its LED components accounted for LED of the total cost of the lamp, the 40-50% is difficult to profit. Therefore, unless the price of foreign LED components fell sharply, otherwise it can only rely on domestic manufacturers to improve product specifications have the opportunity to meet the standard LED street lamp.

Although the LED industry at the present stage Chinese in mainland China and Taiwan are in public works to support local, the street market has great imagination, but lose money to lure manufacturers price bidding is not a permanent solution. Government blindly release orders, but also to think about how to support the domestic LED related industry to improve product specifications and technical autonomy, is the healthy development of the industry.

Delta power: by the power supply device to integrate the advantages of hard work LED rising star

Power supply manufacturers delta days before the launch of LED lighting products series, to show the achievements in environmental protection and energy saving industry. Delta power which published two LED street lamp, luminous efficiency in the excellent performance.

The modular design of the SLDT series, LED light source adopts foreign manufacturers of LED lamps, the luminous efficiency after 1000 hours of aging after the lighting test is still as high as 65Lm/W, powerfactor 0.97, LED lighting standards in Taiwan, up to the standard of Class-2, is now in Taoyuan, Yilan and other devices.

Another SLDN series of 120WLED street lamp, it is a completely homemade LED street lights. By delta electric and Qi photoelectric, can be jointly developed by precision. COB package LED components of this paragraph by Qi Han photoelectric 10W lamp, nengti is using heat pipe separation design for heat dissipation, and in appearance also invited experts design, successful integration of aesthetics and other cooling demand.

Xinyuan Sheng: a number of thermal patented technology known LED street lamp manufacturers

Located in the five shares of the Xinyuan Sheng as its English name Thermoking, with a unique heat dissipation technology for the company's core competitiveness, in the LED street lamp market also received considerable acclaim. Xinyuansheng temperature by thermal conduction technology speeding will generate the LED heat evenly, so that each LED chip temperature of plus or minus 1 DEG C. The lamps with dust fall protection design unique, the radiating structure towards the ground, to prevent dust accumulation in the light caused by poor cooling, can avoid LED decay and burning condition, now this design has been applied for the national patent.

In addition, Xinyuan Sheng LED street lights and OSRAM cooperation, the use of OSRAM GoldenDRAGONPlusLED chip, chip efficiency of more than 90lm/w, applied to the luminous efficiency of more than 50Lm/W.

ZhongMeng photoelectric: street lamp manufacturers LED luminous efficiency of the top class

Investment cooperation by UMC and China appliances have launched streetlight ZhongMeng photoelectric the full range of LED products, specifications from the collocation of solar and wind power generation lighting products can be 24W to 140W device in general on the road. In a few months ago in the city of Taipei LED street lamp demonstration project, showing the 101W LED street as an example, the total output lumens of 7156.2lm, the luminous efficiency of the initial value of up to 71lm/w as measured in the top class international manufacturers; part LED using 96 Nichia083 (BT), Powerfactor 0.98.

In the two part of the optical design, is to use the lens to enhance the light distribution curve and enhance the intensity of illumination. According to the demand of lighting lanes and sidewalks, with large angle optical configuration in the bat wing running direction, unilateral vertical maximum angle of 62.5 degrees, wide irradiation is four times the height of the lamp rod; the road inside to the outside direction using a unique asymmetric optical design, the effective allocation of road inside and outside light weight. In the traditional lamp configuration conditions, without changing the pitch and angle, can meet the various specifications of CNS.
