THORLABS M365LP1 Manual

Description

Thorlabs' M365LP1 Mounted LED has a nominal wavelength of 365 nm, outputs more than 1350 mW
of power, and is mounted to the end of a large Ø57.0 mm heat sink for efficient heat dissipation.
This LED needs to be supplied with a constant current that must not exceed 1700 mA. The current
source must be able to deliver this current at a forward voltage of 4.0 V.

Operating Instructions

Be sure to provide air ventilation in order to avoid overheating, drops in optical power, and
reduced lifetime. Each LED has a characteristic switch-on behavior, which depends on the LED
properties and environment conditions. An important criterion is the heat dissipation. The M365LP1
has a unique thermal and heat sink design that reduces the power decay to a minimum.
The image to the bottom right shows the M365LP1's male connector, which is a standard M8x1
sensor circular connector. Pins 1 and 2 connect to the LED. Pins 3 and 4 are used for the internal
EEPROM. Only use these connections when using a Thorlabs LED driver.
After an LED is switched on, it will warm up which can cause a decay in optical power. The heat
sink of the M365LP1 provides good thermal management, reducing the loss of power as the LED
reaches its equilibrium temperature.
