Latest Patents

Among her latest patents is a groundbreaking device that involves bonding an optical element to a light-emitting device (LED). This invention features at least one LED die mounted on a submount, with an optical element thermally bonded to the LED die. The design ensures that the LED die is electrically coupled to the submount through contact bumps that have a higher temperature melting point than that used for the thermal bonding. In one implementation, a single optical element is bonded to multiple LED dice, which are mounted on the submount, ensuring that both the submount and the optical element have similar coefficients of thermal expansion. Additionally, the optical element or LED die may be coated with a wavelength converting material, allowing for precise testing and adjustment of the wavelengths produced.

Another notable patent involves a common optical element for an array of phosphor-converted light-emitting devices. This device shares similar features with her previous invention, emphasizing the importance of thermal bonding and the use of wavelength converting materials to achieve desired light outputs.
