It is amazing what is available for 10 - 20 dollars. Some of the LED drivers have a dimming input on the low voltage side. Not sure of the detailed implementation of a din temperature controller with 4-20 mA output, but it might be as simple as tl431 shunt reference and a resistor network to map 4-20 mA to the 1 - 10 VDC analog input of an LED driver (there are a plethora available "Meanwell led driver" is one that comes to mind).
