LED Light’s Origin

In the 1960s, scientists developed LED based on the principle of semiconductor pn junction luminescence. The LED developed at that time was made of GaAsP, and its luminous color was red.

After nearly 30 years of development, the familiar LED has been able to emit red, orange, yellow, green, blue and other colors. However, the white LED used for lighting was developed only after 2000.

Tennie Chen is responsible for sourcing and supplier evaluation, with a focus on balancing product quality, cost efficiency, and supply chain reliability. My role involves identifying trustworthy manufacturers, comparing quotations, analyzing total landed costs, and ensuring compliance with international standards. I always prioritize long-term partnerships over one-time deals, aiming to work with suppliers who can provide consistent quality, competitive pricing, and flexible solutions. When making purchasing decisions, I evaluate not only the product itself but also the supplier’s production capacity, lead time, and after-sales support, ensuring that every cooperation contributes to sustainable business growth.
