The LED device under test conditions of Ts=25∘C and relative humidity (RH) = 30% at a forward current of 1A, the electro-optical and absolute maximum rating parameters are comprehensively outlined as follows. In Table 1, the electro-optical characteristics reveal that the device exhibits a peak wavelength (λp) of 385 nm, a radiant flux (Φe) of 1.65 W, a forward voltage (VF) of 3.6 V, a spectrum half width (Δλ) of 11 nm, and a radiation angle (θ) of 115 degrees. These values collectively define the core optical and electrical performance of the component under the specified operating current.
Moving to Table 2, the absolute maximum ratings establish the safe operational and storage boundaries for the device. The forward current (IF) has a minimum rating of 0.2 A, a typical value of 1.0 A, and a maximum limit of 1.4 A, ensuring the device operates within a controlled current range. The junction temperature (Tj) is capped at 125°C, while both the operating temperature (Topr) and storage temperature (Tstg) span from -40°C to 100°C, highlighting the device’s robustness across extreme environmental conditions. Additionally, the thermal resistance from the junction to the solder point (RθJ−S) is specified at 3.8 °C/W, a critical parameter that governs the device’s thermal management capabilities and overall reliability. Together, these specifications provide a complete framework for evaluating the device’s performance, operational limits, and thermal behavior in practical applications.
The LED device under a forward current IF=1A, as presented in Tables 3 and 4. Table 4 first clarifies the meaning of the binning codes: Z1Z2 corresponds to Peak Wavelength (measured in nm), Z3Z4Z5 represents Radiant Flux (in W), and Z6Z7 denotes Forward Voltage (in V), establishing a clear framework for categorizing device performance across three critical parameters.
Table 3 then elaborates on the specific binning ranges for each parameter. For peak wavelength (under Z1Z2), there are two primary bins: m1 spans from 380 nm to 385 nm, while m2 covers 385 nm to 390 nm, ensuring precise wavelength grouping for applications requiring consistent spectral output. In terms of radiant flux (under Z3Z4Z5), two flux bins are defined: Q60 ranges from 1.60 W to 1.76 W, and Q76 extends from 1.76 W to 1.94 W, allowing for classification based on optical power output. For forward voltage (under Z6Z7), three voltage bins are specified: Z4 (3.3 V to 3.4 V), Z5 (3.4 V to 3.5 V), and Z6 (3.5 V to 3.6 V), which enable sorting devices by their electrical operating voltage characteristics. Together, this binning structure provides a systematic method to classify individual LED devices according to their peak wavelength, radiant flux, and forward voltage, ensuring consistency and compatibility in end-use applications by grouping components with tightly controlled performance parameters.
