Ip65 Waterproof Subway Tunnel Cable Passage Belt Corridor Lighting Aluminum 50w Led Explosion Proof Light
the craftsmanship focuses on thermal management and electrical safety. The SMD2835 LED chips, known for their reliability and efficiency, are mounted on an MCPCB (Metal Core Printed Circuit Board). The MCPCB's aluminum substrate acts as a primary heat sink, drawing thermal energy away from the LEDs. This board is then 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 acts as a passive heat sink. This sophisticated thermal pathway is crucial for maintaining the LEDs at an optimal junction temperature, thereby guaranteeing the high light efficiency of 100-110 lm/W, stable color temperature (5500-6500K), and long service life.
The driver compartment is a masterclass in safe, reliable electronics packaging. The driver, supporting a universal AC100-265V input, is potted or encapsulated within a sealed chamber using thermal conductive potting compound. This potting material serves multiple purposes: it immobilizes components against vibration (critical in mines or belt corridors), provides an additional layer of moisture and corrosion protection, and further aids in heat dissipation from critical driver components. All electrical connections are made via robust, corrosion-resistant terminals within certified explosion-proof enclosures, preventing any spark generation.
Product advantages:
- It complies with ATEX explosion-proof standards and is suitable for use in flammable and explosive environments.
