In 2021, despite the presence of COVID-19, global economic activity recovered significantly compared to 2020. In Asia, epidemic control has been relatively successful, with various business activities gradually resuming in the second half of 2020. In Europe and the United States, various sporting events and commercial activities will also resume from the beginning of 2021. Overall, the economic impact of COVID-19 is gradually easing, which also allows the LED lighting industry to see a clear recovery in 2021 after a certain period. Fall year.
TrendForce predicts that the global LED lighting market will reach $64.6 billion in 2021, up 9.2% year-over-year. SMD is still the mainstream, but product uniformity is serious. The growth of the lighting terminal market has also contributed to the growth in the production of LED lighting terminals. LED packaging market. At present, LED packaging products in the market are mainly divided into SMD and COB products, and LED lamps have almost disappeared from the lighting market. SMD LED packaging technology has a low threshold and strong market demand. According to TrendForce statistics, over 95% of the LED devices on the market are SMD products. In recent years, SMD product specifications are concentrated in 2835 and 3030, resulting in more serious product uniformity and more intense market competition. COB Characteristics Outstanding technical performance, market positioning for high quality commercial lighting. Another packaging technology is COB (Chip on Board). COB is a chip-on-board packaging technology that uses conductive or non-conductive adhesives to attach the chip to a substrate, and then achieves an electrical connection by connecting wires. It can not only simplify the production process and reduce the cost of the lead frame, but also has the advantages of lower thermal resistance and better heat dissipation effect. Compared with SMD LEDs, COB has the following advantages: 1. Higher packaging efficiency, more economical COB packaging and SMD production processes are not much different, but COB packaging is much more efficient in terms of dosing, separation, easy separation and packaging. Compared with SMD LED devices, COB LED modules can save the cost of packaging, lighting module production and light distribution. 2. Lower thermal resistance The SMD package thermal resistance structure is glue-solder joint-solder paste-copper foil-insulation layer-aluminum chip-matrix bonding, while the COB package structure is adhesive-aluminum chip-matrix bonding. The thermal resistance of the entire COB package is much lower than traditional SMD packages. Therefore, the life cycle of LED lamps using COB packaging technology is longer. 3. When packaging SMD with high-quality lighting, several discrete components are installed on the PCB, forming an LED light source module, which has problems with light spots, glare and numerous shadows. The COB package is based on the integrated package, which is a surface light source with a large viewing angle, easier adjustment, and can reduce the loss of light refraction. 4. Application Advantages The COB transmitter is easy to use. The transmitter can be installed directly into the luminaire without any other procedures. In contrast, traditional SMD transmitters need to be pre-wired and then fixed to the PCB using reflow soldering. In an application, this is not as convenient as COB. COB devices have a light emitting surface, which makes it easier to achieve color uniformity and higher quality spot images. Therefore, COB devices are widely used in high-demand places such as high-end hotels, high-end retail stores, or high-end commercial lighting market scenarios such as museums. In recent years, the smart lighting market has been in a stage of rapid development. Well-known manufacturers such as Signify, Opple, and NVC Lighting continue to release smart lighting products. COB technology is widely used in the smart lighting market. For example, temperature controlled dual color temperature COB emitters can solve many of the technical and structural design problems faced by smart lighting emitters and can be the best choice for smart lighting. In addition, its integrated package structure helps achieve smaller light-emitting surface area, higher brightness, and integration of dual color temperature, which is conducive to maintaining a constant light emission angle, more convenient for the secondary optical design, and makes light spots more uniform. . In the field of health care and education, the concept of healthy lighting has received more and more attention in recent years and is gradually being accepted by the mass market. For example, LED table lamps require a higher quality light source than other lamps due to the need for close viewing. COB illuminators are more suitable for LED table lamps. The COB luminous body table lamp has many advantages, such as no flicker, no electromagnetic radiation, low power consumption, high luminosity and high color rendering index. This is a new generation light source that is as close as possible to natural light and has a significant impact on protecting the eyes and preventing myopia. The international giants are still in the dominant position, and the Chinese players are actively growing. The COB market is not very price sensitive due to technical reasons. Market barriers and high-end applications. Thus, the market for COB products is still dominated by international giants, especially in developed countries such as Europe and North America. However, with the development of technology in recent years, the competitiveness of Chinese manufacturers’ products is rapidly increasing. The upward trend in the number of Chinese players is obvious. What’s more, with the popularization of COB technology, in addition to the commercial lighting market, due to the trend of abandoning the main lamp design in recent years, COB products are gradually being introduced into the home lighting market. More and more families are starting to use lighting products such as spotlights and spotlights, which are the main application of COB products. This is expected to further increase market demand for COB packaging.
From a global perspective, Japanese manufacturer Citizen will continue to hold the number one position in COB packaging in 2021. For many years, Citizen has been a leader in COB packaging both in terms of technology and revenue scale. In 2021, although the market share of mid- and low-end COB has declined, it still holds the absolute leading position in the high-end COB market. Citizen’s COB market share remains relatively high, especially in the European and North American markets. CREE continues to maintain its #2 position in the world. CREE is the only manufacturer in the world that uses SiC as an epitaxial LED substrate. Although in recent years SiC chips have been gradually withdrawn from the market due to high cost, CREE is still targeting the high-end lighting market. Therefore, CREE mainly promotes high power and COB products. High power products are mainly used in street lights, outdoor high power lighting and other products, while COB products are mainly used in commercial lighting scenarios through distribution channels. Lumileds is one of the world’s largest manufacturers of LED packaging. The mobile LED flash market is dominated by Lumileds. It also has an important position in the lighting market and is the main supplier of Signify. While Lumileds’ COB revenue does not make up the bulk of its total revenue, it still ranks third in the world. The top ten other major COB case manufacturers include Ledteen, Bridgelux, Lightning, TongYiFang, Samsung LED, Hongli and Luninus. Among them, Ledteen has shown rapid growth in recent years, entering the supply chain of international giants, with rapid growth in production capacity and rapid increase in production volume. In addition, Bridgelux is also developing rapidly in the COB market. After the Kaixingda merger, Preh has further expanded its COB product portfolio, which can meet the needs of more customers at different levels, and COB revenue has shown significant growth. In addition to the top 10 manufacturers, there are also a number of outstanding manufacturers in the field of COB packaging, such as Shengpu LED, Orlando, etc. (Organized by LEDinside)
