20 Watt EdiPower LEDs

aber — Thu, 07 Aug 2008 06:23:59 +0000

Edison Opto, a Taiwan based high power LED packaging manufacture, has introduced its popular product, 20Watt EdiPower. The device is measured at 14.5mm x 14.5mm x 0.7mm, with luminous flux of 1,000 lumens for cool white LED (CCT:5,000~10,000K), and 780 lumens for neutral white LED (CCT:3,800~5,000K), and 620 lumens for warm white LED (CCT:2,670~3,800K) at a drive current of 1,400mA.
The circuit design is a 4 parallel 4 series connection, and the operating voltage is approximately 12.0~15.6V. The thermal resistance of EdiPower is 2 °C/Watt; with applicable heat dissipation, the lifespan is expected to exceed 20,000 hours (Tj=105℃). EdiPower are available in cool white, neutral white, warm white, blue, green, amber, red color, and high CRI(color rendering index) series.

The multi-chip ultra high power EdiPower Series deliver never before seen luminous flux output from a single emitter. The superficial illuminating nature of EdiPower makes them the preference in task lighting, high specification down lighting, street lighting, PAR20~38 LED Lamp Series , projector, spot lighting ,and high profile architectural lighting.

Assembly & Soldering
We suggested using EdiPower with Star (ALPCB) will be easier to apply in lighting applications. The EdiPower with Star can use M3 screws to fix on the heatsink or other metal utilities. It’s strongly recommended using thermal grease between Star and heatsinks.

An effective thermal design relies on heat conduction and dissipation. The conduction path which heat travels is dependant on material properties while dissipation depends heavily on the surface area of the heatsink.

Therefore, it is important to provide a fast heat conduction path for the LEDs by reducing the contact resistance between the interfaces. One common method is applying thermal grease. Thermal grease is also known as gap filler; its main purpose is to provide a direct thermal path from heat source to heatsink device.

Bright LED and Unity Opto see improvement in July revenues

Taiwan LED packaging company Unity Opto's July revenues were NT$236 million (US$7.7 million), up 23.7% from NT$191 million in June. Meanwhile, Bright LED has posted July revenues of NT$329.8 million, a 2.3% growth sequentially and 2.5% growth on year, according to data available from the Taiwan Stock Exchange (TSE).

New Ligitek facility to triple company's LED capacity and double its solar module capacity by 2009

Emma — Thu, 08 May 2008 07:37:10 +0000

LED packaging company Ligitek Electronics is building a new facility at Shulin Datong Technology Park with a total investment of over NT$1 billion (US$32.5 million), and the company expects the new facility to help increase its monthly capacity of SMD LEDs by three times, while doubling its solar module capacity.

Ligitek CEO Jackson Torng indicated that the company aims to increase its monthly SMD LED capacity from 20-30 million chips to 60-70 million chips by 2009, with production mainly targeting plat panel display applications and general lighting. The company has already started shipping small volumes of high-power LEDs to the China and Europe markets, Torng pointed out.

Ligitek's solar module production is done through its subsidiary, Ligitek Photovoltaic, in which Ligitiek recently increased its investment capital to NT$210 million. Ligitek is also hoping to bring in investment from Japan-based Marubeni, with the goal being that Marubeni take a 3-5% stake in Ligitek Photovoltaic.

Torng indicated that Ligitek Photovoltaic's annual capacity will expanded from 35MWp to 60~70 MWp by 2009.

The subsidiary will contribute more than NT$100 million to Ligitek's revenues in May, with the contribution even having a chance to surpass NT$200 million, amid strong current order visibility, Torng stated. Ligitek's total revenues for April were NT$151 million, up 60.7% from the same period last year, but down slightly from March 2008 revenues of NT$160 million. Torng indicated April revenues were affected by a shortage of material for its solar module business, though he added the company has secured sufficient supply for May.

LED market slow in 2Q08

Emma — Wed, 07 May 2008 05:18:46 +0000

The LED sector in Taiwan generally had weaker-than-expected sales in April despite players' optimism that orders would be picking up in the second quarter.

LED packagers Unity Opto Technology and Harvatek saw their April sales drop sequentially.

Unity said shipments of applications for LED backlighting dipped in April amid clients' inventory adjustments. The company's April revenues declined 4.6% sequentially to NT$292 million (US$9.58 million), which nevertheless represents a 24% on-year increase.

Unity said shipments to the LED backlighting segment will return to normal in May.

Harvatek's revenues for April dropped 6% sequentially to NT$282 million, with the company predicting limited revenue growth for the first half of 2008. With an order visibility of one to two months, Harvatek said the high season will not come until the third quarter.

While sales performance for the second quarter may not be weak, margins for the quarter will be able to stay at similar levels to those for the first quarter, the company said.

But LED chipmaker Formosa Epitaxy managed to see a 2.51% sequential growth in April revenues to NT$162 million, a company sales record. But the company pointed out that while the LED market saw better-than-expected demand in the first quarter, growth in the second quarter has been slow.
