Current status of LED lighting SSL product supply chain

1. LED chip and package

The vast majority of LED chip and package manufacturers, such as: Lumileds and Cree in the United States, Osram Osram Opto Semiconductors in Europe, Seoul Semiconductor and Samsung in South Korea, Nichia Semiconductor in Japan. In North America, LED package makers Lumileds and Cree are in the top 10 worldwide by revenue. Still tied for first place with Nichia, OSRAM Opto and Seoul Semiconductor in LED packaging for general lighting applications. Commercialization of LED chips and packages in Asia, especially in China, with companies such as Sanan Optoelectronics and Mulinsen. According to Strategies Unlimited, it is expected to grow at a CAGR of 2.3% between 2019 and 2024.

2. LED lamps

The production of LED lamps is distributed around the world, but concentrated in Asia for common lighting such as downlights and flat panel lighting. Because LED luminaires can be bulky, resulting in high shipping costs and long lead times, luminaires may be designed based on regional building types and lighting design preferences. Many large American lighting companies such as Acuity Brands, mean, Hubbell lighting and GE Current have production sites in Mexico and the United States to serve the North American market.

3. OLED panel lighting manufacturing

OLED light source technology and LED technology were developed in the same period. OLED light sources can be very efficient, but cannot match the cost and longevity of LED technology. OLEDs provide a soft diffuse light source that can provide low-glare lighting and are located close to the lighting task. OLED technology has gained a considerable share in the high-end mobile phone market and is also increasing in the large TV market. It is currently used for lighting The output of OLED panels is very low.
