YAHAM is a fast-growing global manufacturer of LEDs

YAHAM is a fast-growing global manufacturer of LEDs, displays, infrared and optocoupler components serving various applications in the lighting, consumer, computing, automotive, telecommunication and industrial market segments. Everlight’s annual growth over the past ten years is the combined result of its well-engineered products, highly efficient in-house manufacturing facilities and extensive global supply chain. Founded in 1983,led high bay light today is a $300 million company headquartered in Taipei, Taiwan, with over 4,000 employees and operations in China.

LED lighting fixtures have accounted for fully half of all Underwriters Laboratories (UL) approvals in Taiwan, reports the Taiwan branch of the safety certification organization, comparing with the average 30% ratio worldwide, according to a report on Taiwan Economic News.As a major player in the global LED industry, Taiwan supplies 26% of the worldwide demand for LED devices, second only to Japan, according to a local industry research institute. The island’s LED revenues are expected to reach NT$74 billion (US$2.1 billion at NT$34; US$1) this year, up about 20% from 2008. Worldwide, the annual growth rate is 15.7%.

UL Taiwan recently worked with the government-supported Industrial Technology Research Institute (ITRI) to certify ITRI’s alternating current (AC) LED light source modules and components under UL’s Subject 8750, completing the world’s first North American UL verification of semi-finished and finished AC LED light sources. UL worked out its safety-verification standard specifically for LED devices as light source, dubbed Subject 8750, in 2005.Insulation is usually the main issue that UL addresses for high-voltage electrical appliances, says Peter Lee, director of UL Taiwan’s conformity assessment service department. "With AC LED products," he notes, "the distance between anode and cathode needs to be widened, and this is the main consideration of 8750."
