Of 350 mA. Table 2 shows the light output flux and light output flux efficiency of PiS WLEDs and PiG WLEDs. The light output flux of the PiS WLED and the PiG WLED was 142.4 and 133.2 lm, respectively. Meanwhile, the light output flux efficiencies were 118 (PiS WLED) and 110 (PiG WLED) lm/W.Figure 3 shows the light-emitting path of the PiS WLED and the PiG WLED. We observed that in the yellow light emitted by the phosphor of the PiS WLED, blue light was emitted in all directions, and a small part of the light was refracted back to the interior and then reflected through the cavity of the lead-frame. The white light emitted by the PiG WLED blue excitation phosphor was also emitted in all directions. However, a part of the light was completely reflected or refracted back to the interior owing to the interface between the phosphor and the encapsulant, and it was reflected again through the light-receiving cavity of the lead-frame. Another part of the light was refracted back to the phosphor glass, and the light loss of repeated reflections resulted in the lower light output of the PiG WLED than that of the PiS WLED. 3.2. Dynamic Aging at Room TemperatureDynamic aging was performed at room temperature at the operating current of 350 mA for 1008 h to the capture light output flux, CCT, and color rendering index (CRI). Figure 4 shows that the normalized light output flux drift of the PiG WLED and the PiS WLED for 1008 h reached 110% and 111% of the initial value, respectively. Figure 5 shows the CCT drifts of the PiG WLED (+0.5%) and the PiS WLED (+0.2%). Figure 6 shows the CRI drifts of the PiG WLED and the PiS WLED at 0.8% and 0.7%, respectively.

From the lead-frame was observed. Two samples of 25 pieces each did not show the phenomenon of non-brightness, and no infiltration of red ink was recorded after dipping. Figure 8 shows the external photo of the PiG WLED after the impact duration of saturated vapor-pressure test and the completion of red ink immersion. 4. ConclusionsThe CIE 1931 (x,y) distribution of PiG WLEDs was more concentrated than that of PiS WLEDs. The CIE 1931 x and y coordinate deviations for the PiG WLED were 0.4% and 0.7%, respectively. Meanwhile, the values for the PiS WLED reached 1.4% (x) and 2.7% (y). The PiG WLED exhibited a more concentrated distribution of CIE 1931 (x,y) and CCT. The drift range of the PiG WLED CCT was from −44 to +21 K, which indicates a better concentration compared with that of the PiS WLED CCT at −69 to +113 K. No significant difference was observed in the light output, CCT, and CRI drift between the PiG WLED and the PiS WLED at an operating current of 350 mA during 1008 h of aging at room temperature. As for the thermal properties, the PiG WLED Tj decreased from 88.4 to 81.3 °C, and the Rth decreased from 37.4 to 35.6 °C/W compared with those of the PiS WLED. In the saturated vapor pressure test, the PiG WLED showed the same excellent material bonding strength as the PiS WLED, and no unlit or red ink infiltration samples were found. Therefore, PiG WLEDs had better color temperature and concentration of color coordinates, but a slightly lower light output flux than PiS WLEDs. Compared with PiS WLEDs, the PiG WLEDs showed a better performance in terms of the thermal properties (Tj and Rth). PiG WLEDs can also attain similar results to PiS WLEDs under normal-temperature aging and saturated35 Best Pi Day Jokes 2025 - Funny Math Jokes and Pi Day Puns

2025-04-06Measure the junction temperature (Tj) and convert the thermal resistance (Rth) [23,24]. The surface temperature (Ts) of the second layer of silicone encapsulant was measured with an infrared thermal imaging camera (TiR125, Fluke Co., Everett, Washington,, USA). We used a multi-channel temperature inspection recorder (GL-840M, GRAPHTEC Co., Yokohama, Japan) to record the LED case temperature (Tc) in real time. The light output of WLEDs was measured by an integrating sphere system (ISP-500, Optimum Optoelectronics Co., Hsinchu County, Taiwan). 3. Results and Discussion 3.1. Light PropertiesWith the PiG WLED CCT of 5564 K as the standard, the PiS WLED was produced. As shown in Figure 2, the YAG phosphors were doped with the encapsulant at concentrations of 8.5 and 9 wt.%, and the CCTs were 5649 and 5311 K. The CCT of YAG phosphor doped at 8.5 wt.% concentration was close to that of the PiG WLED. Therefore, the YAG doping concentration ratio of 8.5 wt.% in the encapsulant was used for PiS WLEDs in this study.Figure 2 shows the distribution of PiG WLED and PiS WLED samples in the CIE 1931 coordinate graph. PiG WLEDs had a lower CIE chromaticity coordinate shifting ratio and smaller CCT differences than the PiS WLEDs. Table 1 summarizes the deviations of CIE 1931 x and y coordinates and CCT for the PiS WLED (8.5 wt.%), the PiS WLED (9.0 wt.%), and PiG. The proportion of deviations of CIE1931 x and y coordinates on the same axis was discussed. The deviation values of CIE1931 x and y coordinates were 0.4% and 0.7% for the PiS WLED (8.5 wt.%), respectively, and the values were 1.4% (x) and 2.7% (y) for the PiG WLED. The light output flux of PiS WLEDs and PiG WLEDs were measured and compared by using an integrating sphere at an operating current
