Since the second half of 2016, despite an overall recovery in the LED industry, it has continued to face intense market competition. The sector has undergone significant restructuring, with a clear division among companies in terms of size, technology, and capital. As a result, LED packaging firms that possess scale, technological, and financial advantages are better positioned for future growth.
Zhaochi Energy-Saving Lighting has been deeply involved in the LED packaging field since its establishment. After nearly seven years of focused development, it has become a medium-sized supplier in the LED backlight segment for TV applications, known for high-quality products and excellent customer service. It is also one of the major suppliers in the LED lighting market, highly recognized by top international brand clients.
The company primarily engages in the research, development, production, and sales of LED devices and components. Positioned within the midstream of the LED supply chain, Zhaochi focuses on two core application areas: LED lighting and LED backlighting. Its LED lighting products are mainly used for indoor illumination, while its backlight products are applied in LCD TVs, computers, smartphones, and tablets.
Thanks to its clear positioning, Zhaochi Energy-Saving has experienced rapid growth in recent years. With the surge in market demand, the company is expanding its production capacity significantly. In June of this year, the Nanchang High-tech Zone-based investment in LED epitaxial chip production completed its industrial and commercial registration in August 2017. This investment will add 1,000 new LED packaging lines at Jiangxi Zhaochi.
Currently, Zhaochi operates 500 packaging lines, with a monthly output of approximately 4,000 to 5,000 K. The company plans to add another 100 lines by the end of the year.
While scaling up is one key strategy, Zhaochi has always prioritized high-end product lines, avoiding low-end, homogenized competition. It closely follows trends in LED packaging technology, continuously improving both technological and industrial innovation. By increasing technical content and product value, Zhaochi expands its product range horizontally and differentiates itself from competitors.
Notably, at this year’s Hong Kong Autumn Lighting Fair, Zhaochi showcased COB, CSP, AC LED modules, and filaments as key products, successfully attracting numerous domestic and international buyers.
**Increased Market Acceptance, Promising Future for AC LED Modules**
According to Tang Liang, Zhaochi’s energy-saving product manager, “Our AC LED module is an export-oriented product designed for the mid-to-high-end market. It currently sells tens of thousands per month and continues to grow.†Indeed, in 2017, AC LED linear modules emerged as a new profit driver for the industry. These modules integrate the light source, power, wiring, and heat sink, making luminaire designs more space-efficient and gradually gaining market acceptance.
However, some industry experts remain skeptical about AC LED modules, questioning their maturity and suitability for the mid-to-high-end market. Tang explained, “There are two main ways to promote AC LED modules: partnering with well-known brands to leverage their popularity, or targeting mid-to-high-end customers who prioritize design and quality. Foreign markets, in particular, don’t just focus on price but demand higher quality. With clear positioning, there's a great opportunity.â€
Zhaochi’s AC LED modules are primarily targeted at foreign markets, with limited presence in the domestic market. According to Tang, this is due to Shenzhen’s lack of labor cost advantage, the intense domestic price war, and the higher risk of quality issues with AC modules. Additionally, the company avoids product conflicts with certain clients.
**Continue to Expand COB Product R&D Investment**
In the past two years, the demand for COB (Chip-on-Board) has grown rapidly, especially in high-end commercial lighting, where its penetration rate is steadily increasing. Outdoor lighting is also seeing a rise in COB adoption, prompting more manufacturers to enter the market.
Zhaochi continues to invest heavily in new COB products. With improved packaging processes, COB’s high-temperature resistance and brightness have seen significant improvements. Orders for COB products have surged in the first half of the year.
Tang said, “We’ve upgraded our COB products, adding high-quality models for specific lighting segments such as aquatic, clothing, home, fruits, and vegetables.†For high-end products, Zhaochi is focusing on optimizing light-emitting types and reducing the emitting area to improve light distribution. They also use precipitation processes to enhance quality, heat resistance, and reliability.
In terms of cost-effectiveness, Zhaochi emphasizes large-scale production, aligning product parameters with real market needs. Their COB lamps achieve around 80lm/W, balancing quality and cost performance. Monthly sales of these COB products now reach between 3 million and 5 million units.
**Improve Product Performance, Comprehensive Layout for CSP**
After last year’s debate over CSP (Chip Scale Package) marketization, the first half of this year saw renewed interest following the transfer of CSP fluorescent film technology from a Japanese firm. Despite initial misunderstandings about CSP performance and usability, more companies are now designing products tailored to its characteristics.
Zhaochi has adjusted its strategy to meet market demands. Currently, CSP energy-saving modules are widely used in backlighting and are expanding into general lighting applications. The performance of CSP products has been continuously improved.
In the first half of this year, Zhaochi completed the development of new lighting products with various specifications, including CSP1111, CSP1313, CSP1515, and CSP1919. They also developed high-pressure CSP lighting products based on the CSP1313 specification.
With continuous innovation and strategic expansion, Zhaochi Energy-Saving Lighting remains well-positioned to capitalize on the evolving LED market.
Off-Grid Solar Inverter
The Off-Grid Solar Inverter is compact, efficient, and reliable, with built-in MPPT charge controller and pure sine wave output.Off-grid solar inverters are essential components of off-grid solar power systems, which are designed to provide electricity in remote areas where grid power is unavailable.
Materials used in off-grid solar inverters typically include:
1. Printed circuit boards (PCBs) – These are used to mount and interconnect electronic components such as resistors, capacitors, transistors, and integrated circuits.
2. Power semiconductors – These components, such as MOSFETs and IGBTs, are used to switch the DC input from the solar panels into AC output for use in household appliances.
3. Transformers – These are used to step up or step down the voltage levels of the AC electricity produced by the inverter.
4. Cooling fans – These are used to dissipate heat generated by the inverter during operation.
The production process of off-grid solar inverters typically involves the following steps:
1. Design and prototyping – Engineers design the circuitry and layout of the inverter using computer-aided design (CAD) software. Prototypes are then built and tested to ensure functionality and efficiency.
2. Sourcing components – Manufacturers source the necessary electronic components, PCBs, transformers, and cooling fans from suppliers.
3. Assembly – Workers assemble the components onto the PCBs using automated pick-and-place machines or manual soldering techniques.
4. Testing – Each inverter is subjected to rigorous testing to ensure that it meets safety and performance standards. This includes testing for efficiency, voltage regulation, overload protection, and temperature control.
5. Packaging – Once the inverters have passed testing, they are packaged and prepared for shipment to customers.
