In recent years, the development of all kinds of LED lights products in Taiwan has flourished, especially in Taiwan and the mainland 2008, all are planning many L-E-D demonstration road projects, which provide a motive power for the continued growth of led urban lamp industry.

In 2008, luminous efficiency was 45 lm/W, by the end of 2009 Led street lights manufacturer has published luminous efficiency 80lm/W. Despite the quality of the products 80 lm/W luminescence efficiency, whether can pass the end of 2008 announcement CNS15233 standard specification requirements. Because timely support from governments' expansion of domestic demand, luminous efficiency for it street light products advanced in all walks of life, rise again into the L-E-D street lamp industry, making it significantly progress in energy research and development. We believe in the near future, led street lamp luminous efficiency can progress to completely replace the current traditional street light in the form of high pressure sodium lamp.

Of all LEDs lights products currently, can be roughly summed up as extruded aluminum heat sink processor, fin type radiator processor, and combined with heat pipe type heat sink processor, which according to the design of the heat sink processor. And the aluminum extrusion type thermal processor is mostly processor exposed appearance into lamps and lanterns. The advantages of this approach for the thermal processor is relatively low cost, especially the mold development costs are more competitive. But in high wattage products research and development, must pay attention to the weight. Because male gauge light pole in the stress of the bear will have certain limitations, and therefore in high wattage products, generally all is the use of fin type radiator, or adopt the way of application of heat pipe in heat treatment plant design.

Besides heat processor development, another important role in LED street light structure is power supply. Because the general it lighting products for dc drive way, and Led street lights manufacturer must be customized for each style LED lights product. But according to the national product safety specification has differences, so we need to adjust circuit, in order to comply with the safety standards of product sales to all over the world. From our LED street light project experience, the phenomenon of the death of the LED street light lamp, most of the proportion, is caused by the unstable power supple. So the product stability of the power supply, also affect the LED street light for outdoor use, whether it can maintain good droop control in three years.
