PL-560C | 568 | （x=0.4416, y=0.5348） | 11~13 |
PL-625（ Nitride ） | 618 | （x=0.6277, y=0.3715） | 9~11 |
Item No. | Color | Luminance value（PL） | Proportion | Granule distribution（D50） | Compatible wavelength（λd） |
PL-540C | Yellow | ≧98* | 1.2 | 7~10um | 450~470±1nm |
PL-625 | Salmon pink | ≧98* | 1.2 | 7um | 450~470±1nm |
*Luminance value (PL) are tested through comparison with the standard sample provided by Taiwan HUNG-TA , one of the agent of NEMOTO & CO., LTD. in Japan.
Meanwhile, we can offer fluorescent tablet used for LED encapsulation. There are three kinds of fluorescent tablet measured in thickness 50μm, 75μm, 100μm.
