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 industry. 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. 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. Despite the quality Led Street lamps of the products 80 lm/W luminescence efficiency, whether can pass the end of 2008 announcement CNS15233 standard specification requirements.
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. We believe in the near future, LEDs street lamp luminous efficiency can progress to completely replace the current traditional street light in the form of high pressure sodium lamp. Besides heat processor development, another important role in LED street light structure is power supply.
But in high wattage products research and development, must pay attention to the weight. 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. Because the general it lighting products for dc drive way, and Led street lights manufacturer must be customized for each style LED lights product.
The advantages of this approach for the thermal processor is relatively low cost, especially the mold development costs are more competitive. In 2008, luminous efficiency was 45 lm/W, by the end of 2009 Led street lights manufacturer has published luminous efficiency 80lm/W. 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.. And the aluminum extrusion type thermal processor is mostly processor exposed appearance into lamps and lanterns
