High voltage LED lamps for retrofit lighting applications

Everlight Electronics Co., Ltd. has launched a range of high voltage LEDs especially suitable for solid state retrofit LED lamps.

Everlight's new HiVo series comprises a 1W, 2W and 4W solution. The ceramic packaged single chip LED provides a luminous flux of 80 / 100 lm at 48-55VDC in a color temperature of 3000 / 5700 K. The 2W product with two LED chips connected in series achieves 140 lm for 2700 K at 95-111VDC. The 4 chip LED with 275 / 375 lm for 3000 / 5700 K is available for voltages of 95-111V in North America and Asia and 190-220VDC in Europe. All HiVo components are supplied in a ceramic package with dimensions of 3.5x3.5mm for the 1W and 6.0x6.0mm for the 2W and 4W


The closer the HiVo LED's voltage is to mains RMS voltage, the fewer the components needed in the driver solution. Because the HiVo LED's voltage closely matches the mains RMS voltage, the need for a converter in the driver solution is completely negated. When Everlight's new HiVo LEDs are implemented into an LED integral lamp the full driver solution is no longer needed. Only a bridge rectifier, resistor, and capacitor are needed for very basic operation, resulting in higher overall efficiency of and a decrease in bill of material costs for the LED integral lamp.
