1. An LED lamp module (1), configured for arrangement in a device (100) for carrying out a photochemical reaction, comprising:
a plurality of LEDs (3); and
a carrier body (6) to which the LEDs (3) are fastened,
wherein the carrier body (6) with the LEDs (3) is arranged in an interior space (11) of the LED lamp module (1),
wherein the interior space (11) is delimited by a transparent wall (10, 10a) and by a housing (12, 15),
wherein the transparent wall (10, 10a) is arranged in a corresponding manner to the LEDs (3),
wherein at least one electrical supply line (7) for electrically connecting the LEDs (3) extends through the housing (12, 15),
wherein the plurality of LEDs (3) is divided into LED groups (2),
wherein each of the LED groups (2) has a predetermined number of LEDs (3),
wherein the LEDs (3) of each LED group (2) are connected in series, and
wherein each LED group (2) is connected to a respective driver device (4) as a constant current source (Iconst) for operating the LEDs (3) of the respective LED group (2),
wherein each driver device (4) is arranged on the carrier body (6) in the interior space (11) of the LED lamp module (1) adjacent to the LED group (2) to which is connected,
wherein each driver device (4) is connected in series to the respective LED group (2) and forms an LED current branch, and
wherein the LED current branches are connected in parallel to a constant voltage source (Uconst) via the electrical supply line (7).
