Abstract EN
We demonstrated a technique requiring little phosphor that used white light-emitting diodes (WLEDs) containing composite silica colloidal photonic crystals (c-SCPhCs) for developing the warm-WLEDs (w-WLEDs).
WLEDs containing c-SCPhCs enhanced luminous efficacy 5.6% more than commercial w-WLEDs did.
We used a UV adhesive curing method to improve the adhesion properties of the c-SCPhCs.
A reliability analysis (RA) test was performed on the WLEDs containing c-SCPhCs, applying a high temperature and high relative humidity (85°C/85 RH) during WLEDs operation at 120 mA.
During a RA test of 2500 h, no visible degradation in optical performance was observed.
We implemented a novel, inexpensive technique for producing high luminous flux w-WLEDs that can be used in residential light.
