In the 600-square-meter store of Jinluda Crystal Lighting, a partner of Longmeiya Optoelectronics Technology Co., Ltd., even in the off-season, there is still a constant flow of passengers. And this is the first store in the traditional crystal lamp brand of Dengdu Ancient Town to apply LED main light source. It is true that the "LED light engine" is not a new word in the industry, but it can be fully applied to the replacement of crystal light source, and the company that has experienced more than one year of production and sales "inspection", currently only Longmeiya Optoelectronics Technology.
So what is the beauty of the “LED Light Engine†that has been patented for practicality, appearance, etc., and can stand firm in the competition of international brands including Philips Lighting, Osram, Panasonic, Toshiba, etc.? To this end, our reporter interviewed Mr. Lai Di, the technical director of Longmeiya Optoelectronics.
Gaogong LED Reporter : How many companies are currently developing and mass producing LED light engine products at home and abroad? What is the level of similar products and brands (including key indicators such as heat dissipation, life, light efficiency, and light decay)?
Rydy : "LED Light Engine" is defined as a combination of LED modules and drivers. At present, there are many domestic and foreign R&D and mass production of LED light engine products, including Philips Lighting, Osram, Panasonic, Toshiba and General Electric of the United States, all of which belong to the Zhaga Consortium organization, in order to easily design LED lighting products. It is planned to standardize an optical engine (a module composed of LEDs, drivers, and optical components) embedded in an LED lighting fixture, and submit it to the International Electrotechnical Commission (IEC) as an international standard.
The NUMIA TECHNOLOGY LED light engine is in line with the principles of composition and structure and the standardization required by Zhaga's LED light engine. Longmeiya LED light engine is a heat-dissipating LED light engine, which is divided into independent light source type LED light engine module and integrated light source type LED light engine module.
Longmeiya heat-dissipating LED light engine adopts organic deposition method to produce Longmeiya heat-dissipating graphite material (patented) with excellent heat dissipation performance. Its excellent heat dissipation performance exceeds metal materials such as copper and aluminum, and it has excellent chemical and physical stability. Excellent conductivity and directional heat dissipation performance can also effectively shield electromagnetic radiation and absorb nuclear radiation. Furthermore, it has successfully developed and produced a variety of LED application products (patent pending): crystal lamp (decoration + lighting + energy saving), candle lamp, bulb lamp, MR16, module modular lamp (high bay lamp, street lamp...) Wait.
Gaogong LED Reporter : What is the working principle of your company's cooling system? What are the main advantages of ultra-high thermal conductivity graphite compared to other thermal materials in the industry?
Lai Di : With the rapid development of LED technology, many products on the market are becoming more and more miniaturized, especially the miniaturization of high-power LED products. Taking high-power LED lamps as an example, as the power used per unit area is getting larger and larger, the heat generated is also increased. To ensure that high-power LED lamps can operate reliably, it is possible to select products in a timely manner. It is important to remove heat to prevent heat-dissipating materials that affect the actual life of the product due to the accumulation of heat.
The structure of Longmeiya heat-dissipating LED light engine is as follows: high-power LED light source component, metal heat-conducting column (referred to as "thermal-conductive column"), ultra-high-conductivity heat-dissipating graphite body.
Longmeiya graphite plasticizing heat-dissipating material works: heat sinking speed is fast and high efficiency; directly and indirectly improve the temperature exchange between heat source and environment, autonomous heat exchange, heat deposition of heat source and reasonable transfer and exchange, so that the heat source The internal thermal deposition temperature is controlled within a safe range. That is to have a higher heat dissipation performance.
In fact, the heat-dissipating graphite material does not affect the performance of other components in the product during the process of removing the heat of the heating element in time, and is suitable for making various heat-dissipating parts, especially the heat generated by high-speed movement of electrons. The heat-dissipating graphite material developed by Longmeyer Optoelectronics has excellent chemical and physical stability, excellent electrical conductivity, directional heat dissipation performance, and can effectively shield electromagnetic radiation and absorb nuclear radiation.
Gaogong LED Reporter : What are the core advantages of your company in terms of heat dissipation and PC light-transmissive materials? What are the main heat dissipation materials on the light engine that are different from other LED products in the industry?
Lai Di: Longmeya Optical PC material has high light transmission PC and high diffusion PC, high optical transmittance, high diffusion optical performance, UV resistance, yellowing resistance, high temperature resistance. Advantages: high light transmission PC transmittance ≥95%; high diffusion PC light transmittance ≥85%.
Advantages of other heat-dissipating materials in the industry: light weight, small size, fast heat dissipation, etc. In particular, many specific spatial environments and limitations of many factors in real life make it possible to make minor changes in the original structure, thereby achieving energy conservation and environmental protection requirements.
Gaogong LED reporter: When did the Longmeiya LED light engine project start to be established, what is the research and development process, and what is the annual investment in research and development? At the beginning of the project, what kind of development stage is the light engine in the LED industry?
Lai Di: The research and development of Longmeiya thermal LED light engine was officially established in 2008. The original intention of the project research and development is to solve the technical bottleneck of the emerging energy-saving and environmentally friendly LED lamps - heat dissipation. It is well known that conventional metal materials have good thermal conductivity, but have poor heat dissipation properties. The inherent physicochemical properties of graphite make it extremely heat-dissipating. However, due to the high requirements of the preparation process, low efficiency and low cost performance, it has always become a bottleneck hindering the development of graphite heat dissipation materials. The graphite plastic heat-dissipating material developed by Longmeiya Optoelectronics has superior heat dissipation performance, high production efficiency and consistency, and mass production, thus providing a high cost performance advantage. In the LED heat dissipation industry, it has the advantages of light weight, small size, fast heat dissipation and free combination.

The off-grid inverter is an inverter used in off-grid solar power generation systems. Its main function is to convert the direct current generated by solar panels into alternating current to meet the power demand in off-grid environments, such as in remote areas, In camping, boats, or moving vehicles.
Main effect:
Converts the direct current generated by solar panels into alternating current to supply the power needs of homes, mobile devices, or other electrical appliances.
Off-grid inverters are usually equipped with battery energy storage systems, which store excess power so that they can continue to supply power when the solar panels cannot generate enough power.
Differences from On-Grid Inverter:
Connection method: Off-grid inverter is an inverter used in the off-grid system and does not need to be connected to the grid. They are often used in places where there is no access to the grid, such as remote areas, wild camping, or outlying islands.
Grid requirements: Unlike on-grid inverters, off-grid inverters do not need to meet grid requirements and standards because they are not connected to the grid. They can operate independently and can be adapted to different off-grid environments.
Self-sufficiency: The off-grid inverter is equipped with a battery energy storage system, which can store excess electricity so that it can continue to supply electricity when the solar panels are unable to generate electricity. This makes the off-grid system self-sufficient and not dependent on an external grid for power.
Application scenarios: Off-grid inverters are widely used in remote areas, camping, ships, mobile vehicles, and some special-purpose scenarios. On the other hand, grid-connected inverters are mainly used in home, commercial, and industrial photovoltaic power generation systems connected to the grid.
In general, the main function of the off-grid inverter is to convert the direct current generated by the solar panels into alternating current to meet the power demand in the off-grid environment and achieve self-sufficiency by being equipped with a battery energy storage system. In contrast, on-grid inverters connected to the grid are mainly used to integrate solar power into the grid, realize the interaction between solar power and the grid, and comply with the requirements and standards of the grid.
