LED power supply, as the core component of LED lighting system, undertakes the key task of converting utility power (AC power) into low voltage DC power required by LEDs, and at the same time stabilizes the output current through constant-current driving technology to prevent LEDs from accelerated aging due to current overload. Its technical characteristics directly determine the energy efficiency, life and safety of LED lamps. According to the latest research report, the global LED power supply market reached $6.461 billion in 2024 and is expected to increase to $11.08 billion in 2031, with a compound growth rate (CAGR) of 4.5% from 2025-2031. This growth is driven by global energy saving and emission reduction policies (e.g. EU ERP Directive, China’s “dual carbon” target) and emerging application scenarios such as smart lighting and plant lighting.
II. Supply Chain Structure: Localization and Globalization Game
- Upstream: accelerated domestic substitution of key components
IC chip: domestic enterprises have achieved 60% localization rate in the field of driver IC, but high-end chips (such as intelligent control chips supporting IoT integration) still rely on international manufacturers.
Capacitors and inductors: local companies reduce costs through large-scale production, driving capacitor prices down 18% from 2020, but high-end film capacitors still need to be imported.
Raw material volatility: copper prices rose 22% year-on-year in 2024, leading to a 5%-8% increase in power supply costs, which companies mitigated through strategic stockpiling.
- Midstream: manufacturing shift to Southeast Asia
Affected by the U.S. tariff policy, Chinese LED power supply enterprises accelerate the layout of Vietnam, Malaysia and other southeast Asia base. For example, a Hangzhou enterprise in Vietnam set up an annual capacity of 5 million units of the factory, avoid tariff costs at the same time close to the american market.
- Downstream: Diversification of application scenarios drives demand
Industrial lighting: accounting for 32%, the demand is focused on high power (> 400W) explosion-proof power supply, such as a power supply company for the petrochemical industry customized IP67 protection level products.
Plant lighting: 2024 market size of 35% year-on-year growth, LED power supply needs to support 0-10V dimming to match the plant growth cycle, a Shenzhen enterprise related products accounted for 25%.
Smart home: the proportion of IoT-integrated power supplies increased from 8% in 2020 to 19% in 2024, and smart power supplies supporting Wi-Fi/Bluetooth dual-mode became mainstream.
Third, the market competition pattern: technical barriers and brand premium differentiation
- Global Top 5 vendors accounted for 45% of the share
TOP1: Leading with 18% market share, relying on brand advantages to focus on high-end commercial lighting market, the average price of products is 30% higher than the industry average.
TOP2: Focusing on the industrial power supply segment, its revenue will grow 22% year-on-year in 2024, and its market share of 400-800W products will reach 28%.
TOP3: The technology leader among Chinese manufacturers, with an R&D investment of 8%, its digital power technology has improved energy efficiency to 96%, close to the international first-tier level.
- Cost-Technology Drive for Chinese Manufacturers
Price competition: the average price of Chinese manufacturers’ products is 25%-40% lower than that of European and American brands, and costs are compressed through large-scale production.
Technology breakthrough: a Hangzhou enterprise launched an intelligent power supply that supports DALI 2.0 protocol, breaking the monopoly of international manufacturers in protocol compatibility.
IV. Policy environment: Compliance pressure and green opportunities coexist
- Escalation of international trade barriers
U.S. 301 tariffs: China’s LED power supply export tax rate from 10% to 25%, resulting in the compression of corporate profit margins by 5-8 percentage points.
EU ERP Directive: Require power supply energy efficiency ≥ 94%, forcing enterprises to eliminate backward production capacity (e.g. eliminating 0-25W products with energy efficiency below 90%).
- Domestic policy support
“Dual-carbon” goal: Promote LED retrofit in public buildings, with government procurement of $1.2 billion by 2024, requiring power supply life of ≥50,000 hours.
Special subsidies: 15% tax breaks for companies developing high power density power supplies, e.g., an electrical company’s R&D investment increased by 20% after receiving the subsidy.
V. Market trends and future outlook
- Market Size Forecast 2025-2031
Optimistic scenario (CAGR 5.2%): $11.5 billion market in 2031 if global energy efficiency policies ramp up, with drivers including plant lighting penetration increasing to 40% and smart power supply accounting for over 35%.
Conservative scenario (CAGR 3.8%): If geopolitical conflict intensifies, the market size could be $10.5 billion, reflecting the risk of supply chain disruption.
- Direction of technology evolution
High power density: the third generation of semiconductor applications to reduce the size of the power supply by 40%, an electronics company launched a GaN power supply power density of 30W/in³, leading the industry average.
Intelligent: the share of power supplies embedded with AI O&M modules will increase from 12% in 2024 to 30% in 2030, enabling fault prediction and energy efficiency optimization.
Photovoltaic energy storage integration: demand for power supplies compatible with solar charging is surging, and Guangdong Dongling Power related products’ revenue will increase by 50% year-on-year in 2024.
- Regional market opportunities
Southeast Asia: CAGR of 7% is expected from 2025-2031, benefiting from industrial lighting demand due to manufacturing shift.
Middle East: Saudi Arabia’s “2030 Vision” to promote the construction of smart cities, LED power supply market size of 15% annual growth in the design of dust and sand outstanding demand.
VI. Strategic recommendations
- Supply Chain Optimization
Diversified purchasing: establish cooperative relationships with domestic second suppliers to reduce dependence on a single supplier.
Localized production: Setting up assembly plants in Mexico and India to avoid tariffs while staying close to the market.
- Technology Upgrade Path
Intelligent power supply R&D: Invest resources in developing products that support the Matter protocol to seize the first opportunity in the smart home market.
Material innovation: the use of nanocrystalline magnetic core to reduce iron loss, so that the power supply efficiency increased by 2-3 percentage points.
- Branding and Channel Building
DTC model: through Amazon, Lazada and other platforms to reach consumers directly, a power supply company online channel share has increased from 5% in 2020 to 18% in 2024.
Industry solutions: for agricultural customers to launch “light source + power supply + control system” integration package, enhance the unit price by 30%.
Conclusion: Driven by global energy-saving policy and digitalization wave, LED power supply industry is shifting from “cost competition” to “technology-ecology-compliance” comprehensive competition. Enterprises with intelligent delivery capability and localized compliance system are expected to increase their market share by 3-4 times in the next five years. Investors should focus on high power density power supply, photovoltaic energy storage integration and other segments of the track, as well as in Southeast Asia, the Middle East and other emerging markets with a first-mover advantage of the manufacturers.
