The 1W package has the CRI of 90 and efficacy up to 110lm/W for lower voltage (15V) operation while the 3W package has the CRI of 90 and efficacy up to 105lm/W for higher voltage (50V) operation. Both these packages have the CCT of around 3000K. The 1W lamp combined several Epistar’s blue and red LED chips in the same package, coated with yellow/green phosphor. The power consumption and total lumens can be adjusted by modifying the combinations of the LED chips.
The 3W lamp used one high-voltage monolithically integrated DC multiple-chip array combined with several Epistar’s red LED chips. Yellow-green phosphors were used in both 1W and 3W packages. A bridge structure can be used with the 3W lamp to achieve the AC drive. These packages can be used in the E12/E14 candle light, E26/E27/GU10 light bulbs, PAR light and other applications for high efficacy warm white.
a provider of digital power IC systems products and technology, today announced the release of the iW3620 Digital Controller for led high bay light applications. It is the industry’s first LED driver IC for 5-40W luminaires with primary side regulation that eliminates the need for an opto-coupler and related components thereby reducing bill-of-material cost and improving reliability.
The iW3620 is designed for both the residential and commercial lighting markets for retrofit incandescent and halogen lamp replacement with solid-state lighting. The device’s high frequency operation enables the LED driver module to fit directly inside space-constrained T5, T8, T10 or T12-size fluorescent tubes or MR16 and PAR30 retro-fit incandescent and halogen lamp replacement housing.
