    摘要： High density multi-chip LED devices are described. Embodiments of the present invention provide high-density, multi-chip LED devices with relatively high efficiency and light output in a compact size. An LED device includes a plurality of interconnected LED chips and an optical element such as a lens. The LED chips may be arranged in two groups, wherein the LED chips within each group are connected in parallel and the groups are connected in series. In some embodiments, the LED device includes a submount, which may be made of ceramic. The submount may include a connection bus and semicircular areas to which chips are bonded. Wire bonds can be connected to the LED chips so that all the wire bonds are disposed on the outside of a group of LED chips to minimize light absorption.

    摘要： Multi-chip LED devices are described. Embodiments of the present invention provide multi-chip LED devices with relatively high efficiency and good color rendering. The LED device includes a plurality of interconnected LED chips and an optical element such as a lens. The optical element may be molded from silicone. The LED chips may be connected in parallel. In some embodiments, the LED device includes a submount, which may be made of a ceramic material such as alumina or aluminum nitride. Wire bonds can be connected to the LED chips so that all the wire bonds tend the outside of a group of LED chips. Various sizes and types of LED chips may be used, including vertical LED chips and sideview LED chips.
