Semiconductor Lighting, also known as Light-Emitting Diodes (LEDs), is a solid-state lighting device that uses a semiconductor chip as the light-emitting material. When electric current passes through the semiconductor, electrons and holes recombine, releasing energy in the form of photons. This process allows LEDs to emit various colors, including red, yellow, blue, green, cyan, orange, purple, and white. LED-based lighting products are fixtures that use these diodes as their primary light source. Semiconductor lighting offers significant advantages such as high efficiency, energy savings, environmental friendliness, and ease of maintenance. It has become a key solution for energy conservation and emission reduction, marking a major revolution in the history of lighting, following incandescent and fluorescent lamps.
**Development Status**
**1. International Industry Enters New Growth Phase**
Currently, global semiconductor lighting technology is experiencing rapid development. In 2015, the luminous efficiency of cold white LED devices reached 168 lm/W. LEDs have become the mainstream light source in the lighting industry, accounting for over 30% of the market. With an efficiency of 108 lm/W, the application of LEDs is expanding across various sectors, especially in automotive and agricultural fields. The industrial scale continues to grow, with an annual growth rate exceeding 20%. Market demand is shifting from energy-saving focus to intelligent and diversified applications. Many multinational lighting companies now derive more than half of their revenue from LED products. The widespread adoption of LED lighting has played a crucial role in reducing energy consumption and emissions. The U.S. expects LED penetration to reach 84% by 2030, potentially cutting lighting power usage by 40%. Developed countries are actively promoting energy-saving policies and standardization efforts to maintain control over the global semiconductor lighting market.

**2. China’s Lighting Industry Continues to Rise**
The Chinese government has placed strong emphasis on the innovation and development of semiconductor lighting technology. During the “Twelfth Five-Year Plan†period, China made significant progress, laying a solid foundation for becoming a leading force in the semiconductor lighting industry.
Key technologies have seen breakthroughs. By 2015, the luminous efficiency of power-type white LEDs exceeded 150 lm/W. Independent silicon-based LED chips achieved over 140 lm/W. Deep ultraviolet LEDs with a wavelength of 293 nm and output power up to 4.8 mW were developed. Overall LED lamp efficacy surpassed 85 lm/W. Innovative applications, such as smart lighting, visible light communication, and agricultural lighting, are emerging rapidly. Technologies like Micro LED and QLED are gaining international attention, and cross-disciplinary integration is creating new opportunities.
In terms of industry scale, China's semiconductor lighting sector reached 424.5 billion yuan in 2015, a 21% increase from the previous year. Despite a slowdown in growth, the average annual growth rate during the Twelfth Five-Year Plan was still close to 30%. China is a major player in the global lighting industry, with rapid growth in LED functional lighting. In 2015, total lighting sales reached about 560 billion yuan, with LED functional lighting valued at 155.2 billion yuan, growing by 32.5%. Domestic LED production reached 6 billion units, with domestic sales at around 2.8 billion. The domestic market share of LED lighting was approximately 32%, while exports reached 12 billion USD, up by 15%.
Standardization efforts have also advanced. National and industry standards related to semiconductor lighting have been released, and China has actively participated in international standardization work. Testing capabilities have improved, and energy-saving and quality certifications are being implemented. Two phases of energy efficiency systems have been launched. Standardization pilot projects have also made progress.
The competitive landscape of the industry is gradually taking shape. The number of listed companies focused on LED technology increased from 2 in 2010 to 25 in 2015. Revenue growth has continued, and the issue of "increasing revenue without increasing profits" has eased. Mergers and acquisitions have become a major trend, with leading enterprises forming industry clusters. The industry is moving from coastal regions to central and western areas, showing regional development characteristics.
**Facing the Situation**
Today, addressing global ecological issues and energy shortages has become a top priority for societies worldwide. Green, low-carbon, and sustainable development have become key directions for economic and social progress. The energy-efficient and eco-friendly nature of semiconductor lighting makes it a critical tool in achieving energy-saving and emission-reduction goals. Under the new normal, China’s semiconductor lighting industry has entered a new stage of development, facing both challenges and opportunities.
**1. Global Industry Development Shows a New Pattern**
With the acceleration of global climate governance, technological advancements, and evolving market demands, the global semiconductor lighting industry is entering a new phase of rapid growth. Technological breakthroughs have exceeded expectations, shifting from efficiency improvements to quality enhancements, with changing hotspots. The industry is transitioning from technology-driven to application-driven, with accelerated cross-disciplinary integration and extended industry boundaries. Application areas are broadening, and innovative applications are becoming new growth points after the replacement stage. Semiconductor lighting is moving from simple lighting to on-demand and beyond-living environments. Major resources are concentrating in industry leaders, with integration trends shifting toward cross-border collaboration. Companies are shifting from "big and complete" to "small and beautiful," moving from manufacturers to service integrators, and accelerating innovation. Global industrial structures are adjusting, with traditional leaders like the US, Japan, and Europe being challenged by South Korea and China. China has become the world’s largest producer, user, and exporter of semiconductor lighting products.
**2. China Faces Challenges and Opportunities**
Despite fierce international competition, China’s semiconductor lighting industry still faces several challenges. First, the market-oriented institutional mechanisms and business models need further exploration, and policy systems must be strengthened. Second, original innovation and high-end technological capabilities remain weak, with no fully formed enterprise innovation system or public R&D platform. Third, most companies are small or medium-sized, with low industrial concentration and a tendency toward homogenized competition, leading to overcapacity. Domestic competition is intense, and export products are mainly OEM or ODM, with no internationally recognized brands yet. Fourth, product quality, energy efficiency standards, and application specifications are not systematically established. Product specifications are chaotic, and quality varies. Standards lag behind, and test data consistency needs improvement. Some products are not included in certification systems, and there is a lack of evaluation of standard implementation and lighting effects. Additionally, there is no effective market supervision mechanism, allowing low-quality counterfeit products to flood the market and disrupt fair competition.
However, there are also significant opportunities. First, China’s urgent energy-saving demand makes LED lighting a realistic choice for achieving green development. Second, the industry is highly integrated and labor-intensive, serving as a key entry point for national strategies like the “Belt and Road†and “Made in China 2025.†Third, the growth rate has shifted from “super high speed†to “medium speed,†accelerating enterprise transformation. Fourth, the integration of LED technology with other fields is creating new applications, showcasing the power of cross-disciplinary innovation. Fifth, the global semiconductor lighting industry is reshaping, with China making breakthroughs in core technologies. The massive production capacity will support China’s strategic window in the semiconductor and third-generation semiconductor industries.
During the “Thirteenth Five-Year Plan†period, China’s semiconductor lighting industry is at a critical stage. By seizing opportunities and overcoming challenges, China aims to not only catch up but eventually lead the global semiconductor lighting industry.
