Fuhua Electronics Institute of Electronics and Optoelectronics has obtained the authorization transfer of AC LED packaging technology, and cooperated with ITRI to AC LED packaging and testing technology, becoming the world's first AC LED packaging component to pass the UL Subject 8750 for Lighting certification in the North American market. Fuhua Electronics is full of confidence in the future development of the LED lighting market.
LED has the advantages of power saving, environmental protection (excluding mercury), long life, fast response, small size, etc., and LED lighting design can be combined with light source characteristics, such as light source directivity, cold light source and color change, etc., LED lighting will become the lighting market Mainstream. In addition to replacing traditional lighting, the future can open up new market application opportunities. The luminous efficiency of LEDs grows at a rate of 20% per year. It is estimated that by 2010, LED light efficiency will surpass all traditional light sources. The investment of LED panel manufacturers in the world has increased rapidly, which has led to a surge in demand for white LEDs. It is estimated that by 2012, the shortage of supply will continue.
LEDs are divided into AC LEDs and DC LEDs. The difference between the two is that the latter must be equipped with a power converter, which can be used after converting AC power to DC power. Because AC LED has many advantages over DC LED, including system product design. Higher degrees of freedom, smaller size, lower system cost and avoid the impact of power converter reliability. In terms of efficiency, the current DC LED is higher than the AC LED, but after being packaged into a system product, the DC LED needs to pass through the power converter, and the actual energy consumption is 15~25%, and the light efficiency is only 50-65lm/W, AC The LED is about 50 lm/W, which is actually quite similar. In addition, although the DC LED has a life of more than 30,000 hours, the maximum life of the system luminaire is actually subject to the electronic components in the power converter, and the life span is about 5,000~10,000 hours. Once the converter has problems, the whole set of system lamps also Will not be available. Therefore, the AC LED system lamps developed by the power converter are not really energy-saving and environmentally friendly, but have a new generation of light sources with a long life.
In response to the energy conservation and environmental protection policies of the global government, countries began to release phase-out plans for energy-contaminated lamps such as incandescent lamps. Most countries will completely ban incandescent bulbs from 2012 and switch to LED lights. In addition to the large-scale development plans of China's ten cities and millions of LED street lights, LED lighting will be particularly dazzling from 2012, and it will last for at least 10 years.
