Current Limit Modes
The following plots illustrate the LED intensity and light coverage of the Aquorea at various beam angles ranging from 0°-80°.
The intensity plot on the left shows the LED intensity as a percentage of the maximum intensity measured for the Aquorea.
The plot on the right shows the percentage of the total light output of the Aquorea that is contained within each beam angle. For example, the 60° circular beam contains 82.7% of the total light output of the LED, this is the sum of the total light output contained between 0-60°.
The LED’s output light intensity can be doubled if the input current limit is removed. This current was limited to 2A by default, but it can be removed using "~device set current limit:5.0" API command. When limit is removed, LED’s current consumption can reach up to 5A depending on brightness setting. For brightness setting if a number more than 100% is chosen, then the microcontroller calculates the maximum brightness available and apply that. For example, when using “~device set lamp:120“, it returns “WARNING: Argument out of range. Value will be clamped.” ”@devicelamp:117“, and maximum brightness 117% will be set. It should be noted that 2A limit can be set back using "~device set current limit:2.0" API command. The blow graph shows the LED’s brightness in both 2A and 5A modes.

Below graphs shows the LED driver’s Current control (Ictrl) voltage, and Die-LED’s voltage vs. intensity in different modes.
