The document describes the features and characteristics of LR W5AM, LA W5AM, LY W5AM Golden DRAGON Plus Enhanced thin film LED products, including their high-efficiency light source, small size, high brightness, and RoHS compliance.
The Golden Dragon Plus series from OSRAM offers high‑efficiency thin‑film LEDs in three colour variants (red, amber, yellow) with a compact SMD package and clear silicone lens. Typical luminous flux at 400 mA reaches 60 Im (red), 74 Im (amber) and 55 Im (yellow) while the viewing angle is 170°.
The devices are designed for SMT assembly, support reflow soldering and meet RoHS requirements. Electrical ratings include a forward voltage of about 2.2 V (red) at 400 mA, a maximum forward current of 1 A, surge current up to 2.5 A and operation from –40 °C to 125 °C. Detailed wavelength groups and brightness classes are listed for each colour variant.
| Typical Luminous Flux (400 mA) | 60 Im (red), 74 Im (amber), 55 Im (yellow) |
|---|---|
| Peak Wavelength | 625 nm (red), 617 nm (amber), 590 nm (yellow) |
| Viewing Angle | 170° |
| Optical Efficiency (100 mA) | 79 Im/W (red), 95 Im/W (amber), 68 Im/W (yellow) |
At 400 mA the LEDs produce 60 Im (red), 74 Im (amber) and 55 Im (yellow).
The LEDs have a viewing angle of 170°.
