IdealPhotonics' visible light LED diodes, based on III-V compound semiconductors (such as InGaN/GaN and AlInGaP), achieve luminous efficacy exceeding 200 lm/W in the blue (450nm), green (520nm), and red (620nm) bands through precise wavelength tuning via band engineering. Their innovative "quantum well structure" and "surface roughening technology" further enhance external quantum efficiency to over 80%, making them a core light source solution for lighting, displays, and optical communications.Employing InGaN/GaN and AlInGaP multi-quantum-well structures, it achieves full-spectrum coverage (400-700nm) through precise bandgap tuning (wavelength accuracy ±1nm), achieving record-breaking luminous efficacy of 250lm/W, 220lm/W, and 210lm/W in the blue (450nm), green (530nm), and red (630nm) bands, respectively. Its innovative "micro-nano photonic crystal" technology enhances the external quantum efficiency to 85%, and combined with a "multi-chip integration" solution, it achieves a color rendering index (CRI) exceeding 98, becoming a performance benchmark in three major fields: ultra-high-definition display (95% BT.2020 color gamut), intelligent lighting (human-based circadian rhythm control), and visible light communication (10Gbps Li-Fi).
