The LED UV lamps of the DROLED L7x, manufactured by Photo Electronics, series are offered in a wide range of different sizes and powers, making these lamps suitable for many applications, such as: screen printing, pad printing, offset printing, flexo and digital printing.
Our catalog ranges from small lamps from 0.1 W / cm2 for manual use up to lamps up to 16W / cm2 for high productivity industrial use. Our UV LED lamps emit UV-A / UV-V rays exploiting the emission of single diodes, assembled in an array; the LEDs are current-controlled by a microprocessor electronics, integrated in the lamp.
DROLED UV LED lamps emit a different spectrum than traditional UV lamps, since the emission peak is much more selective and centered on specific wavelengths ; this is why it is necessary to use products (paints, inks, etc.) specifically designed to react to UV LED light.
|Lamp power supply
||48V DC ± 0.2 V|
|Maximum power consuption
||from 20 to 3000 W (per singola lampada)|
|Single lamp size
|Distance between LED module and working surface||from 1 to 15 mm|
All the lamps of the DROLED L7x series have built-in electronics and drivers and are air-cooled by fans integrated in the body. Moreover the L70 and L74 models have a serial port with VGA connector (RS485 protocol), which allows cascade connection up to 8 lamps and to use a single system to control them.

Each UV LED lamp model is available in different sizes and can support one or more types of optical systems to improve performance or adapt to specific needs.
|FLAT WINDOW (FW)
Allows complete polymerization a few millimeters from the radiation window
|FOCUSED LENS (FL)
Allows complete polymerization far from the radiation window
|ROD LENS (RL)
It allows the gelification and pinning of inks through direct beam
|ANGLED ROD LENS (ARL)
It allows the gelification and pinning of inks through angled beam
