High-Performance Thermal Management for the Lighting Industry
Precision-engineered heat sinks and thermal solutions designed to eliminate lumen depreciation, ensure color stability, and maximize the lifespan of High-Power LEDs, Stadium Lights, and Automotive Lighting.
The Challenge: Protecting LEDs from Thermal Degradation
High-power LED chips convert a massive portion of energy into heat. Without efficient dissipation, the junction temperature rises rapidly, leading to catastrophic failure.
Lumen Depreciation & Color Shift
Excessive heat permanently damages LED phosphors, reducing brightness and altering the color temperature over time.
Strict Weight Constraints
Suspended fixtures like High Bay lights and Stadium masts require massive cooling capacity but must remain exceptionally lightweight for safe installation.
Harsh Outdoor Environments
Streetlights and architectural lighting demand rugged thermal solutions capable of surviving heavy rain, salt fog, and extreme ambient temperatures (IP65+ requirements).
Automotive LED Reliability
Automotive headlights and LiDAR systems require ultra-compact, vibration-proof cooling that meets zero-defect automotive safety standards.
Jindu’s Advanced Cooling Solutions for High-Power LEDs
By balancing thermal mass, surface area, and airflow dynamics, we manufacture heat sinks that keep junction temperatures strictly within optimal limits.
Cold Forged & Extruded Heat Sinks for Passive Cooling
The industry standard for Commercial, High Bay, and Street Lighting.
Cold Forging (Pin Fin Mastery)
We manufacture pure aluminum (AL1070) pin fin heat sinks via cold forging. This process ensures zero air bubbles, maximum thermal conductivity (up to 230 W/mK), and omnidirectional airflow for superb natural convection.
Custom Extrusions
Cost-effective, high-volume extruded profiles tailored for linear LED fixtures, architectural lighting, and horticultural grow lights.
Lightweight Designs
Our CFD-optimized geometries maximize surface area while stripping away unnecessary weight, making ceiling or mast installations safer and easier.
Skived Fins, Heat Pipes & Liquid Cooling for Extreme Wattages
Engineered for ultra-high-power applications like Stadium Masts and UV Curing.
Phase-Change Integration
For 1000W+ stadium lights, we embed copper heat pipes or vapor chambers into the base to rapidly draw heat away from dense COB (Chip-on-Board) arrays.
Micro-Skiving Technology
We create extremely dense fin structures (down to 0.1mm thickness) to maximize heat dissipation in constrained spaces.
Liquid Cold Plates for UV LED
Providing aggressive, hermetically sealed liquid cooling (100% helium leak tested) for industrial UV LED printing and curing systems where air cooling is insufficient.

Frequently Asked Questions: LED Thermal Solutions
Cold forging uses pure aluminum (like AL1070), which has a higher thermal conductivity (approx. 230 W/mK) than extruded alloys. Furthermore, the pin-fin structure created by cold forging allows for omnidirectional airflow, significantly improving natural convection cooling in round fixtures like High Bays or downlights.
Traditional aluminum heat sinks are too heavy and bulky for 1000W+ fixtures. We utilize high-density skived fins integrated with embedded copper heat pipes or vapor chambers. This rapidly pulls the massive localized heat away from the COB LED array and spreads it across the fins, keeping the fixture lightweight and efficient.
Yes. For outdoor street lights and marine applications, we apply high-quality surface treatments such as severe-environment powder coating, hard anodizing, or electrophoretic deposition (EPD) to ensure the heat sinks pass rigorous salt-spray testing and maintain their integrity for decades.
Absolutely. As an IATF 16949-certified manufacturer, we produce highly precise, zero-defect CNC-machined and die-cast heat sinks tailored for the extreme space constraints, vibration standards, and thermal demands of automotive LED and LiDAR systems.
Poor surface contact traps heat and destroys LEDs. We utilize our 50+ high-precision CNC machines to mill the base of the heat sinks to a flatness tolerance of ±0.005mm. This eliminates air gaps, minimizes the need for thick thermal paste, and maximizes heat transfer from the Metal Core PCB (MCPCB) to the heat sink.
Yes. Our engineering team conducts in-depth CFD (Computational Fluid Dynamics) simulations on your existing design. By analyzing the thermal flow, we can often remove unnecessary material—through advanced fin geometries or skiving—to reduce the weight and cost without sacrificing cooling performance.
