    HC Semitek Launches the “Yi” Serial High-voltage Chips
    2014-04-02

    HC Semitek is committed to the R&D, production, and sales of high-quality LED epitaxial materials and chips. As a chip leader in China, HC Semitek has launched the “Yi” serial high-voltage chips for white light use, including 9V, 12V, 24V, etc. chip products. 12V high-voltage chips have a luminous efficiency of ≥140lm/W under the drive current of 20mA.

    High-voltage chip is connected in series at the chip end for better reliability. High-voltage chips feature the technological innovations of grooves, insulation layers, and interconnecting wires between chips. Thanks to these technical improvements, high-voltage chips require far lower drive current than ordinary chips under the same output power, and can also significantly slash the AC-DC conversion efficiency loss.

    At the packaging side, high-voltage chip eliminates part of the die-bonding and routing processes, saves the cost of gold wires, and boosts the efficiency of equipment use at packaging plants. For application lamps, RC voltage reduction method can cut power supply costs and save costs of materials. The high-voltage chip becomes a low-cost, efficient solution for bulb lamps and fluorescent lamps.

    HC Semitek believes that the high-voltage chip market has promising prospects. As LED becomes more popular in the lighting market and the costs of alternative products in the lighting market, high-voltage chips will see more application innovations. HC Semitek will continue to develop “Yi” serial high-voltage chips according to market segments.
