Shenzhen HSY LED Technology Co., Ltd.

The Founder

15 Years in LED Manufacturing · 9+ Years in Red Light Therapy · Trusted by 50+ Global Brands

In offshore manufacturing, important details are often lost between buyers, sales representatives, engineers, and factory decision-makers. Annie removes this gap.

As the founder of HSY, Annie brings 15 years of experience in LED manufacturing and over 9 years in the red light therapy supply chain. With a bilingual background and a strong understanding of Western business culture, she acts as both the key decision-maker and technical leader at HSY.

Instead of working through layers of middlemen, customers connect directly with the source. Annie quickly aligns customer requirements with HSY’s engineering, SMT, production, and QC teams, helping decisions on pricing, customization, feasibility, and logistics move forward faster and more clearly.

To support long-term partnerships, Annie also leads HSY’s core engineering team on annual visits to key global clients, keeping product development aligned with local market needs.

"I've been in this industry long enough to know what keeps buyers up at night. My job is to make sure you sleep well."
— Annie, Founder of HSY

The R&D Team

Focused on Wavelength Precision, High Irradiance, Thermal Control, and Safety

Spectrum Customization:
Precise tuning of LED wavelengths, such as 660nm and 850nm, to match different therapy goals.

Safety Engineering:
Flicker-free and Zero-EMF circuit designs for safer and more comfortable use.

Thermal Management:
Advanced heat dissipation to support LED lifespan, stable performance, and user safety.

Structural & Functional Upgrades:
Custom housing, smart control panels, and brand-exclusive tooling based on target market needs.

The Sales & Project Management Team

Focused on Commercial Success, Project Control, Compliance Support, and Margin Protection

HSY’s Sales & Project Management team helps customers turn product ideas into successful OEM/ODM projects.

The team does not simply take orders or push catalogs. It works as a strategic manufacturing partner, helping brands, distributors, wholesalers, and online sellers launch products on time, on budget, and on brand.

For OEM/ODM partnerships, HSY’s Sales & Project Management team provides:

Product & Market Fit:
Support in selecting the right specifications, features, packaging, and positioning for markets such as human wellness, sports recovery, pet care, and equine therapy.

Compliance Support:
Assistance with FDA, CE, RoHS, and other compliance-related materials for smoother market entry.

Clear updates from prototyping and packaging to production, quality inspection, final assembly, and shipment preparation.

Supply Chain & Margin Control:
Coordination of material sourcing, production schedules, and delivery planning to help control costs, shorten lead times, and protect customer margins.

HSY handles the factory-side complexity, so customers can focus on marketing, sales growth, and brand building.

The Production & QC Team

Focused on Consistent Manufacturing, Quality Control, On-Time Delivery, and Bulk Order Stability

For B2B customers, a good sample is only the beginning. What matters most is whether bulk orders can maintain the same quality, performance, structure, and packaging standards.

HSY’s Production & QC team ensures that every approved design is manufactured consistently and delivered reliably.

For mass production and quality control, HSY’s Production & QC team provides:

Standardized Production:
Controlled assembly processes from material preparation and component installation to wiring, product assembly, and packaging.

Functional Testing:
Key performance checks for power function, light output, control systems, connection stability, and basic safety.

Aging Test & Reliability Check:
Continuous working tests to identify potential issues before shipment and improve long-term reliability.

Appearance & Packaging Inspection:
Checks on product appearance, accessories, labels, manuals, packaging details, and order accuracy.

Final Quality Control:
Final inspection based on customer requirements and internal QC standards to ensure consistency between approved samples and bulk orders.

HSY’s Production & QC team helps customers reduce bulk order risks, maintain stable quality, and build confidence in long-term cooperation.
