🔬 Modern Chandelier Re-Engineering

🔬 Modern Chandelier Re-Engineering From Failed Integrated LEDs to a Robust 24V Constant-Voltage System 💡⚡ Modern chandeliers often use integrated low-quality LED boards powered by undersized or poorly regulated drivers. Over time, heat accumulation and unstable current cause premature LED degradation, flickering, or total failure. This project documents a full electrical and thermal redesign to eliminate those weaknesses. ________________________________________ 🛠️ Engineering & Technical Breakdown 1️⃣ Failure Analysis 🔥 • Original LED modules showed thermal discoloration and open circuits • Factory wiring insulation had signs of heat stress • The OEM driver lacked sufficient current headroom and thermal protection • LED boards were wired in a non-serviceable series configuration, making repair impractical ________________________________________ 2️⃣ Complete Electrical Decommissioning 🗑️ • All original LED PCBs, wiring harnesses, and connectors were removed • Old solder joints were eliminated to prevent high-resistance hot spots • Chassis was cleaned to remove carbon residue and improve thermal performance ________________________________________ 3️⃣ System Redesign – 24V Constant Voltage Architecture 📐 • Replaced the integrated LED boards with a 24V constant-voltage LED strip system • Installed a 5-meter high-density LED strip, cut and segmented as required • Parallel wiring topology ensures voltage stability and prevents total blackout if one segment fails ________________________________________ 4️⃣ Power Supply Engineering ⚡ • Installed a 24V / 4.3A regulated switching power supply • Provides adequate current margin to avoid overloading • Built-in protections: o Over-current protection (OCP) o Over-voltage protection (OVP) o Thermal shutdown • Eliminates flicker caused by ripple and unstable output ________________________________________ 5️⃣ Electrical Assembly & Craftsmanship 👨🏭 • Low-resistance solder joints using appropriate flux and temperature control • Wire gauge selected to minimize voltage drop across LED segments • Heat-shrink insulation and mechanical strain relief applied at all joints • Proper polarity control to prevent reverse-voltage damage ________________________________________ 6️⃣ Thermal Management Improvements 🌡️ • LED strips mounted to metal surfaces to act as passive heat sinks • Reduced junction temperature significantly increases LED lifespan • Even heat distribution prevents localized LED burnout ________________________________________ ✅ Final Performance Evaluation • Uniform luminous output with no hotspots or dark zones • Stable operation under continuous duty • Improved power efficiency and reduced thermal stress • Fully serviceable and modular system design • Significantly more reliable than the original factory LED implementation ________________________________________ 🧠 Engineering Conclusion By converting the chandelier from a sealed, failure-prone LED system to a serviceable 24V constant-voltage architecture, this upgrade dramatically improves reliability, safety, and maintainability—extending the fixture’s usable life by many years. #DIY #LightingUpgrade #LEDRepair #ChandelierRepair #ModernLighting #LEDStrip #ElectricalWork #HomeLighting #ReEngineering #FixDontReplace #TechDIY #BeforeAndAfter #Restoration #CreativeRepair #WorkshopLife
