Abstract
A state‐of‐the‐art solid‐state lighting (SSL) device comprises a blue light‐emitting device covered with a yellow‐emitting phosphor. In a high‐power SSL device, thermal stability is an essential requirement for the phosphor because the phosphor is constantly irradiated with high‐power blue light, which causes thermal degradation. In this work, a thermally robust phosphor–aluminum composite (PAC) fused with low‐melting glass is introduced. The PAC exhibits a high thermal conductivity of 31.6 W m −1 K −1 and the PAC combined with a 4 W blue laser diode (LD) exhibits excellent thermal stability in luminous flux and chromaticity. Furthermore, energy is recycled in the PAC during lighting by coupling to a thermoelectric (TE) module. In the PAC‐TE system, the output voltage and current reveal 289 mV and 77 mA, respectively, at an output of 430 lumens under a 4 W blue LD. The results provide a starting point for further research in the composite‐material design for energy recycling with high‐power white lighting.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
