Aluminum 4014 SMD LED PCBA Rigid Bar (144 LEDs): The Backbone of Linear Light
Beautiful light starts with a good board. The Aluminum 4014 SMD LED PCBA Rigid Bar pairs a 0.2–4mm aluminum substrate with a dense array of 144 × 4014 SMD LEDs, turning bare components into a finished, ready-to-install light engine. For buyers building tubes, battens and linear fixtures, this board is the fastest route from concept to shipment.
Why Aluminum? Why 4014?
Aluminum substrates pull heat away from the LEDs far better than standard FR4, so an aluminum bar runs cooler, holds its output longer and tolerates higher drive currents. The compact 4014 package allows 144 emitters to sit on one rigid bar with tight, even spacing — the secret to seamless linear lighting with no dark spots. Boards are available in 1, 2, 4 and 6 layers with copper from 0.5 to 4oz to match the load.
6 Application Scenarios Where This Bar Pays Off
- LED tubes & battens — a drop-in light engine for T8/T5 style linear tubes.
- Commercial & office linear fixtures — continuous, glare-controlled runs for offices, retail and galleries.
- Swimming pool & damp-area lights — aluminum base plus sealed assembly suits wet environments.
- Lightboxes & signage backlight — even, edge-to-edge illumination for displays and sign frames.
- Downlights, spotlights & floor lights — a compact engine for recessed and accent fixtures.
- Smart & industrial modules — medical, intelligent-home and industrial-control boards built on the same platform.
