SMD LEDs from mainland China suppliers are in top- and sideview configurations.
Top- and sideview types continue to form the mainstream SMD LED range in mainland China.
Based on package sizes, the first type includes 3528, 5050, 2835, 3014, 3020, 5630 and 5730 variants and the latter kind 010, 020, 335 and 215. Diodes in 3528, 5050 and 2835 lead supply.
In terms of emitted color, pure, warm and cool white, and RGB are the choices.
For chips, makers remain dependent on foreign providers such as Genesis Photonics and Chimei, although some also obtain the component from local companies, one of which is San'an.
The rest of the components and materials, including lenses, PCBs, wires and adhesives, come from domestic enterprises.
The cost of manufacturing inputs rose by 5 to 10 percent in the past year, but some suppliers chose to maintain prices for competitiveness.
In the months ahead, outlay for materials and components are expected to stabilize and keep quotes at current levels.
The products in this gallery have been handpicked by our market analyst for representing current trends in SMD LEDs from mainland China and Taiwan.
