DROLED L7x UV LED lamp by Photo Electronics

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.

Technical data

Lamp power supply	48V DC ± 0.2 V
Maximum power consuption	from 20 to 3000 W (per singola lampada)
Single lamp size	for manual use: 49.5 mm – h 126.5 mm for industrial use: da 43 x 136 x h 289 mm a 403 x 136 x h 266 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.
