R&D underscores high-performance LED drivers/power supplies
Makers of LED drivers or power supplies in China are directing product development efforts toward elevated efficiency, longer life span and smaller size. Low noise and intelligent control are among the objectives as well.
These undertakings are aimed at meeting the varying requirements of a growing application base, which includes panels, displays and lamps for indoor and outdoor use. Suppliers, in particular, are concentrating on large types for road and landscape illumination. These units with about 100W rating are forecast to post solid growth this year because the target lighting has significant cost-performance ratio over traditional counterparts.
Companies are employing technologies such as power factor correction, pulse width modulation, high frequency, zero-voltage and -current softswitching, synchronous rectifier and single switching power supply. So far, many have raised efficiency to more than 90 percent from 80 to 85 percent, and reduced standby energy consumption to less than 1W. These were achieved by using advanced power management ICs and semiconductor components.
Pushing these gains further, makers hope to hurdle technological challenges to expand reach and keep up with foreign competitors.Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs. They will improve the life span of driver circuits with key components such as capacitors that can withstand elevated temperatures.
Achieving greater conversion efficiency, especially in high-power LEDs, is another goal to ensure maximum energy-saving performance of the diode and the application device. Suppliers also strive to increase the dimming ratio and deliver consistent color characteristics in both high- and low-brightness settings. Current R&D efforts,"The current economic environment is putting great pet supply stores strain on veterinarians who are well established in this community," however, are hampered by cost considerations.
Nevertheless, China's LED driver industry continues to progress and is forecast to achieve at least 30 percent growth in sales this year, buoyed by the prevailing trend for environment-friendly lighting.
Domestically, diode-based illumination has become widespread in the past years, with extensive use in the 2008 Beijing Olympic Games accelerating adoption. In the same way, US and EU efforts to replace incandescent bulbs gradually are fueling the switch to the "green" technology,The Scottish company says broken inflatable swimming pools tent poles will be a thing of the past with the introduction of its AirBeam tents, which come with a hand pump to inflate the tent hoops in a claimed three minutes for the smaller models. boosting demand for related components.
At present, the local industry's share of global production is 12 percent based on annual exports of more than 45 million units.
The category represents about 15 percent of China's switching power supplies output. At Ningbo Jiangbei HWZ Electronic Co.t sounds like man and wildlife are on a schedule 40 pvc pipe collision course, but it doesn't have to be that way. Ltd, it accounts for half of yield. The maker churns out up to 800,Camping manufacturer Vango inflatable seat is claiming a first with its innovative pump-up range of tents.000 units monthly. Large-scale operations such as Shenzhen Moso Power Supply Technology Co. Ltd have an annual production exceeding 10 million units.
China has more than 500 makers that mass-produce LED drivers. All come from the SPS segment. About 60 percent of them gather mainly in Shenzhen, Guangdong province. Companies have set up factories there to benefit from a mature supply chain and manufacturing and trading infrastructure, modern transportation system and solid government backing. The city accounts for 25 percent of the aggregate output of the Pearl River Delta region.
