The optoelectronic domain is witnessing an unprecedented paradigm shift from conventional low-voltage (LV) driving configurations to highly efficient High Voltage (HV) LED architectures. Standard LED packages, typically operating at 2.8V to 3.4V, demand massive current loads to achieve high luminous output. This causes severe system-level conduction losses and requires bulky, expensive step-down drivers. In contrast, High Voltage LED chips configure multiple micro-junction structures monolithically on a single substrate, raising the forward voltage threshold ($V_f$) to 12V, 24V, 48V, or even higher (up to 72V or 150V).
From a commercial standpoint, this transition optimizes the entire power conversion loop. High voltage design allows luminaire manufacturers to utilize direct-to-line AC driverless systems or simplified step-down converters. By decreasing operating current, systems minimize ohmic heat dissipation ($I^2R$ losses). This prolongs system lifetime and reduces thermal management overhead. Globally, industrial, commercial, and outdoor public spaces are adopting HV LED chips to fulfill strict energy efficiency mandates, such as the European Union’s Ecodesign Directive (ERP) and the United States’ DLC (DesignLights Consortium) standards.

High Voltage LED Chips are suited for diverse structural layouts where space and efficiency are critical:
HV LED chips pack multiple PN junctions in series within a single die. This configuration increases forward voltage ($V_f$) while lowering current. The reduced current minimizes conduction losses in drive circuitry and trace layouts. It also allows for simplified driver topologies, reducing system bill-of-materials (BOM) costs.
Our factory relies on advanced ERP platforms and strict QA inspections. This quality control spans incoming raw materials, in-process assembly, and final shipping verification. Additionally, our R&D engineers review all custom layout drafts to confirm thermal performance and electrical compatibility.
Yes. We offer fully customizable spectral distributions. We can adjust correlated color temperature (CCT) and deliver high color rendering indices (CRI Ra > 95, R9 > 90) to suit specialized commercial lighting and medical applications.
Standard production runs are completed in 3 to 4 weeks. However, our automated production lines and local supply chain allow us to fast-track urgent requirements in 1 to 2 weeks.
