Technical Specs & Certifications
The LED light heat sink is a critical component in ensuring the performance, efficiency, and longevity of LED lighting systems. At Beauty (STC) Manufacturing Co., Ltd., our heat sinks are engineered to support high-performance LED fixtures that meet stringent technical and quality standards. When paired with our advanced LED modules, these heat sinks enable optimal thermal management, directly influencing key metrics such as lumens per watt, color rendering, and environmental resilience.
Lumens per watt (lm/W) is a measure of luminous efficacy, indicating how efficiently a light source produces visible light. Our LED lighting systems, designed with precision-matched heat sinks, consistently achieve luminous efficacies ranging from 130 to 180 lm/W, depending on the configuration and application. This high efficiency is made possible by the heat sink’s ability to maintain lower LED junction temperatures, minimizing lumen depreciation and ensuring sustained light output over time. The aluminum alloy construction—typically 6063-T5—with optimized fin design and surface anodization maximizes thermal conductivity and dissipation.
Color Rendering Index (CRI) is essential for applications requiring accurate color representation, such as retail, healthcare, and studios. Beauty STC’s LED fixtures, equipped with our high-efficiency heat sinks, support LED chips that deliver a CRI greater than 90. This is maintained over the product’s lifespan due to effective thermal regulation, which prevents color shift caused by overheating. We use high-quality phosphor-coated LEDs from trusted suppliers, ensuring consistency in chromaticity and long-term color stability.
Ingress Protection (IP) ratings indicate the fixture’s resistance to dust and moisture. Our integrated LED luminaire designs—featuring die-cast or extruded heat sinks—support IP ratings up to IP66 and IP67. This is achieved through seamless housing integration, gasket sealing, and corrosion-resistant finishes on the heat sink surface. These ratings make our products suitable for both indoor and outdoor environments, including wet locations, industrial settings, and coastal areas.
Beauty STC is committed to excellence in manufacturing and product reliability. Our heat sinks undergo rigorous quality control, including thermal performance testing, salt spray resistance tests, and material certification. We adhere to international standards such as ISO 9001 and IEC 62717, ensuring consistent performance and safety. Every heat sink is designed in-house using thermal simulation software to optimize airflow and heat transfer, reflecting our dedication to innovation and engineering precision.
In summary, Beauty STC’s LED light heat sinks are integral to delivering high-efficiency lighting solutions with exceptional lumens per watt, CRI above 90, and robust IP-rated protection. Our focus on thermal management and quality manufacturing ensures that our LED systems perform reliably in demanding applications worldwide.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province, represents a significant investment in modern LED lighting production capacity. Strategically located within the Pearl River Delta manufacturing corridor, the Jiangmen factory occupies a purpose-built site of approximately 30,000 square meters. This facility is designed to stringent international manufacturing standards, featuring controlled environment zones for critical processes, comprehensive quality control laboratories, and dedicated areas for raw material storage, component assembly, and finished goods logistics. The layout emphasizes efficiency and traceability throughout the production flow, supporting both high-volume output and specialized project fulfillment.
The Surface Mount Technology (SMT) production lines form the core of our electronics assembly capability at the Jiangmen site. We operate multiple high-speed, high-precision Yamaha YSM20 and YSM10 placement machines, capable of handling components down to the ultra-fine 0201 package size. These machines feature advanced multi-vision systems for precise component recognition and placement, with placement accuracy consistently maintained within ±25 microns.
