Led flash module, leds + PCB PB102673
Led flash module. Inside the opening for the Mitutoyo 10X lens. The 12 power leds are not solderd but connected via 24 x M2 brass screws which press on the led contacts. I can even modify LED types with the same module.
The 12 LEDs are divided into 6 groups. Each time there are two LEDs connected together on the PCB. LEDs shine through the 12 holes of 8mm diameter each. Each group can be controlled separately. The direction and amount of light may be a result set.
The base plate is made of aluminum for cooling. The back of the LEDs have an additional thin special thermal film of 0.2mm in order to have good thermal conductivity. The LEDs can operate continuously at full power.
