Taiwan LED Street Lamp Manufactures 2009


2009-04-09 Optical Semiconductors editor

The year 2009 has been expected to be the year of the rapid expanding of
LED street light market. At present, the LED street light plans have
been launched in batches in many cities in China. In Taiwan, because
of the increased budget in domestic demand, such plans have also been
released. The U.S. and Europe have also begun to adopt LED street
lights in large scales. All these are efforts to replace the
traditional street lights and to use solar energy, wind force and
other recyclable energy types to aid the street illumination in areas
of short electricity supply.


Considering the increasing focus upon LED street light market, LEDinside had visited several LED manufacturers recently to get some knowledge about the standards and developing state of their LED street light products. To discuss this subject, LEDinside has organized the information about the situations of these major LED manufactures for reference of LED industry in future development.

Because the LED street light illumination standards in Taiwan (CNS15233) were officially passed in the later half of 2008, the current released data provided by manufactures are mostly the original value measured by Industrial Technology Research Institute. LEDinside estimates that after the 2nd quarter of 2009, the list of LED street lamps officially certificated by the CNS15233 will be publicized. At that time, there will be a more mature market and more completed policies and actions by local governments. .

View from LEDinside

For the existing LED street lamp manufactures, most of their luminous efficiency original value can reach the Class-3 level of the CNS15233(the original value of 45Lm/W), and some can even reach the Class-3 level(the original value of 45Lm/W). However, only those with the luminous source adopting the LED components produced by the major foreign manufactures(like Osram, Cree, Nichia) can reach the current standard.

However, considering the possible revival of trade protectionism, it is predictable that the LED street lamp components and parts could be restricted to be homemade in many government bidding documents, which could be a tough challenge for the existing manufacturers. Besides, given the fierce competition, the bidders may have to offer rather low price to win the bid. On the other hand, to meet the standard, these manufactures could have to purchase import LED components whose price is 40-50% of the overall cost of the LED lamp socket. In such case, the manufactures could barely benefit. Therefore, unless the import LED component price is decreased by a large proportion, in order to meet the LED street lamp standard, the domestic manufactures would have to improve the specification of their products.

Although China mainland and Taiwan have both been supporting the LED industry through public projects, which has given the street lamp market a promising outlook, it’s still not an effective solution inducing the manufacturers to loss money from low-price bidding. At the same time as the governments release lamp orders, it should also be considered how to help the domestic LED manufacturers to improve their product specification and develop their own technology, and finally to achieve the sound progress of the industry.

 

Delta: the up-and-coming star depending upon power supply device integration

The power supply device manufacturer Delta has newly released a whole series of LED luminous products, displaying its achievements after stepping into the energy saving field. Among the products released, there are two models of LED street lamps which have shown excellent performance in luminous efficiency.

The SLDT series adopts modularity design. The LEDs of its LED luminous source are from foreign manufacturers. After 1000 hours of lighting test, the luminous efficiency of the lamp can still reach as high as 65Lm/W, and the power factor 0.97. The products have reached Class-2 level in street light standard of Taiwan, and have already been applied in practice in Taoyuan, Yilan and other areas.

Another 120W LED lamp product of the SLDN series is totally homemade. It is co-developed by Delta, Lustrous and NENG TYI Precision. The 10W COB packaged LED components of Lustrous and the separate-designed heat dissipating passage of NENG TYI is adopted. And the appearance of the lamp is specially designed by relevant expert to combine the aesthetics and heat dissipating requirement together.
