Nichia Corp of Tokushima, Japan has expanded its Direct Mountable Chip series by introducing discrete color options, a similar technology to chip-scale packaging (CSP). Along with its previously released white options, the Direct Mountable Chip color lineup - consisting of royal blue, green, amber and red - enables lighting customers to take advantage of Nichia’s unique Direct Mountable Chip technology in a wide range of applications.

Nichia says that, with over 50 years of experience in phosphors and 25 years of experience in LEDs, it has capitalized on its history to launch an innovative color solution that utilizes Nichia’s own phosphor and blue die technology, bringing benefits to fixture manufacturers and designers.

By using the same wavelength die in each color, Nichia has harmonized the forward voltage across the entire Direct Mountable Chip family, simplifying electrical circuit designs. Additionally, unlike other discrete color technologies, the internal structure of each Direct Mountable Chip color is the same. So, the directivity and height are also the same, making optical design much easier to manage. Finally, with the phosphor-converted red Direct Mountable Chip, the thermal droop characteristics are significantly improved from traditional red AlInGaP LEDs, it is claimed. This allows for much better in-situ performance and overall color and stability.

Nichia claims that its Direct Mountable Chip family was the first lighting CSP-type to incorporate unique technology allowing for a single-sided 120° lambertian optical pattern, eliminating cross-talk in lumen dense applications. The firm says that, by developing an innovative color lineup, its now expanded Direct Mountable Chip portfolio provides flexibility to all lighting applications, including color tuning, architectural lighting and other commercial and residential markets.
