5x5 Compact High Power UV-C LED Array M5x5-S35-H-350-C
5x5 Compact High Power UV-C LED Array M5x5-S35-H-350-C
This document provides technical specifications and guidelines for the 5x5 Compact High Power UV-C LED Array, model M5x5-S35-H-350-C, featuring S3535-H SMD LEDs by BOLB Inc.
- Output: 3.5W optical at 350mA/LED and 2.5W optical at 250mA/LED.
- Active cooling is required, with a recommended heat pipe rated at 100W dissipated power or above.
- Power supply: 36-40V DC, 3A with voltage stabilization.
- PCB includes a Molex 1.25 mm 6-pin connector and optional Kyocera connectors for power supply connections.
- No additional soldering is required.
The drive current options are 250mA/LED (2.5Wopt) or 350mA/LED (3.5Wopt), with on-board LED drivers selected based on these power selections.
- The I-V curve shows voltage variations per SMD at different currents.
- Irradiance data is provided for various distances, showing significant irradiance at close range when driven at 350mA/LED.
- Examples of thermal management solutions include extruded aluminum heatsinks and heat pipes, with specific temperature measurements provided for different configurations.
- Recommended thermal paste: Gennel G108, 4.63 W/m-K.
- UVC LEDs emit high-intensity ultraviolet radiation, necessitating strict safety precautions.
- Eye and skin protection is mandatory during assembly, testing, and use.
- Direct exposure to UVC light is prohibited, and materials that absorb UVC light should not contact the LED components.
Multiple language warnings emphasize avoiding eye and skin exposure to unshielded UVC products.
