In recent years, the development of various types of LED street light products has flourished in the three places of the two sides. Especially in 2008, Taiwan and the mainland have planned many engineering projects for LED demonstration roads, which injected the driving force for technology to continue to grow in the LED industry.
From the luminous efficiency of LED street lamps 45Lm/W in 2008, the manufacturers have publicly announced the lighting level with 80Lm/W luminous efficiency at the end of 2009. Regardless of the quality of this 80lm/W luminous efficiency product, can it be announced at the end of 2008? The standard requirements of CNS15233, but also because the governments of the government to expand the timely support of domestic demand, let the LED lighting products' luminous efficiency in all walks of life advanced, enter the LED street lamp industry, which makes the research and development energy greatly improved, I believe in In the near future, the luminous efficiency of LED street lamps can be improved to replace traditional street lamps in the form of current high-pressure sodium lamps.
LED street light heat treatment
At present, all LED street lamp products can be roughly classified into an aluminum extrusion heat dissipating processor, a fin type heat dissipating processor and a heat pipe combined heat dissipating processor in the design of the heat dissipating processor, and among them, the aluminum extruded heat dissipating processor is mostly The processor is exposed to the appearance of the luminaire. The advantage of this method is that the cost of the heat dissipating processor can be relatively low, especially the development cost of the mold is more competitive, but in the development of high wattage products, the weight is a must pay attention to The factor, because the public light pole has a certain limit on the stress, so in the high wattage products, it is generally used finned heat sink treatment, or the application of heat pipe design Heat treatment device.
Ceramic capacitor (ceramic capacitor);Ceramic condenser) is also known as porcelain capacitor or monolithic capacitors.As the name implies, ceramic dielectric vessel is a ceramic capacitor with dielectric material.According to different ceramic materials, this kind of capacitor can be divided into low-frequency porcelain dielectric vessel with capacity of 1-300 pF and high-frequency porcelain dielectric vessel with capacity of 300-22 000 pF.According to the structure type classification, can be divided into picture capacitor, tubular capacitor, rectangular capacitor, chip capacitor, piercing capacitor and so on.
