Ip65 Waterproof Subway Tunnel Cable Passage Belt Corridor Lighting Aluminum 50w Led Explosion Proof Light

This industrial-grade lighting solution features advanced thermal management and electrical safety engineering. The SMD2835 LED chips, renowned for their reliability and efficiency, are mounted on a Metal Core Printed Circuit Board (MCPCB). The aluminum substrate of the MCPCB functions as a primary heat sink, effectively drawing thermal energy away from the LEDs. This board is securely attached to the interior chassis of the aluminum housing using thermally conductive epoxy or mechanical fasteners, ensuring optimal heat transfer from the LEDs directly to the massive external housing, which serves as a passive heat sink. This sophisticated thermal pathway is essential for maintaining optimal LED junction temperature, thereby guaranteeing high light efficiency of 100-110 lm/W, stable color temperature (5500-6500K), and extended service life.

The driver compartment exemplifies safe, reliable electronics packaging. The driver, supporting universal AC100-265V input, is potted or encapsulated within a sealed chamber using thermal conductive potting compound. This material serves multiple critical functions: it immobilizes components against vibration (essential in mining and belt corridor applications), provides additional moisture and corrosion protection, and aids in heat dissipation from vital driver components. All electrical connections utilize robust, corrosion-resistant terminals within certified explosion-proof enclosures, preventing any potential spark generation.
