Application Guidelines General Procedures 1. Phosphor: Fultor Phosphor 2. Silicone: GE, Dow Corning, Nusil and others 3. Phosphor Selection: Dependant upon LED chip wavelength and Target CIE, select the suitable phosphors and ( corresponding concentration ratio (provided in concentration ratio table) 4. Weight: Weigh phosphor and silicone in correct ratios provided in concentration ratio table in concentration ratio table 5. Mixing: Mix phosphor and silicone well and place under vacuum in vacuum chamber to eliminate air bubbles 6 Testing: Package 10~20 LEDs for test and validation 7. Heating: Place packaged LEDs in oven at 150C for 60 minutes 8. Measurement and Adjustment: Measure the CIE and adjust the phosphor concentration ratio (or phosphor type) as needed Repeat Step 5~8 until desired CIE is achieved Packaging | Chip wavelength(nm) | Phosphor Type Model | Weight Ratio (Phosphor : Epoxy or Silicone) | Top View | 455-460 455~460 455~460 455~460 | FL-4255 FL-4751 FL-4850 FL-5049 | 8~12:100 10~15:100 20~28:100 25~35:100 | Side View | 455-460 455~460 455~460 455~460 | FL-4255 FL-4751 FL-4850 FL-5049 | 10~15:100 15~25:100 25~30:100 25~35:100 |
