The LEDs in the Corona II modules are selected for color coordinates.
The following chromaticity coordinate groups are used:
cool white | 6E | up to serial number 01149 |
7E | ||
8E | ||
6F | ||
7F | ||
8F | ||
5F | up to serial number 03460 | |
6F | ||
7F | ||
5G | ||
6G | ||
7G | ||
32 | ||
warm white | A636 |
It is not possible to order a Corona II module with LEDs of a specific subgroup. But each Corona II module contains LEDs of the same subgroup, e.g. 7E.
Typical relative spectral emission
θrel = f(λ); TS = 25 °C; IF = 700 mA
Relative luminous flux
Cool white up to SN 01149
In relation to LED current | In relation to junction temperature |
|---|---|
ΦV/ΦV(350 mA) = f(IF); TJ = 25°C | ΦV/ΦV(25 °C) = f(TJ); IF = 350 mA |
 |  |
Cool white up to SN 03460
In relation to LED current | In relation to junction temperature |
|---|---|
ΦV/ΦV(350 mA) = f(IF); TJ = 25°C | ΦV/ΦV(25 °C) = f(TJ); IF = 350 mA |
