摘要

A novel combination of blue LED chips, transparent glass substrates and phosphors with PDMS thin film is demonstrated. The flipchip bonding technology is applied to facilitate this design. The ZrO₂ nanoparticles are also doped into the PDMS film to increase light scattering. The resultant luminous efficiency shows an 11% enhancement when compared to the regular COG device. The variation of correlated color temperature of such devices is also reduced to 132K. In addition to these changes, the surface temperature is reduced from 121°C to 104°C due to good thermal dissipation brought by ZrO₂ nanoparticles.
