As we all know, as a green industry, the LED industry has many advantages such as environmental protection, health, and energy conservation. However, looking ahead, the domestic LED only accounts for about 15% of the lighting market share, and it is very large from 30% to 50% of developed countries. distance. In the future, the LED industry will further increase the degree of industry concentration, and advantageous resources will move closer to dominant companies. How to make LED industry grow stronger? New technologies secretly exert their power to lead the LED industry to a new future.
First, the chip and packaging process is developing rapidly. Light efficiency is improving, and technologies such as flip-chip, high-voltage chip, COB, EMC, and CSP packaging have all developed. Domestic and foreign device products all began to fight light source module products, especially IC integrated products, system integration, modularization and so on. COB devices below 30W are still mainstream products in the market, and there may be significant growth in the future.
Secondly, despite the fact that device manufacturers have thrown up the sound of R&D CSPs and flip-chips without gold wires in the first two years, it has finally become popular this year. Direct-backlight backlights, products for TV displays already have CSP products. For example, the CSP package product is in the form of COB. Multiple small devices are combined in series, and can be assembled indefinitely according to the size of the application. In addition, the performance of the phosphor products related to Gao Xianzhi this year has been outstanding.
Third, high-power mining lamps and floodlights made of EMC devices integrated into the packaging model are increasingly sought after. The development of automotive lighting modularization, market stability needs to be expanded, such as car headlights and turn signals, etc. is a very tempting market cake.
Fourth, smart lighting solutions, smart solutions for homes and business locations have become market trends. Smart lighting is becoming more and more popular. It is a trend and a challenge. The current “App lamp control system” approach is that each product is self-contained from lamp to software and the system has no unified standard or protocol and cannot be interconnected and interoperable. This is a constraint. A major drawback of development.
Fifth, the filament lamp is more mature, many companies rely on leading technology, production and marketing around the world, the market is booming, sapphire substrate filament, etc. have become the main products to replace the old-fashioned silk lamp.
Sixth, there are more and more UV LED applications, plant lighting applications, etc., and the penetration rate is also getting higher and higher. For example, UV LEDs are used in security, disinfection, and curing. The potential market for these LED subdivisions is huge, but they all require large-scale applications to further tap market opportunities.
Nowadays, the advantages of chip packaging technology have emerged. The rapid expansion of industrial equipment, the extension of the display area, and the small lead in backlighting have led to the emergence of smart lighting. The scale of market segments such as plant lighting, medical lighting, and agricultural lighting is also gradually expanding, and has always been the concern of the industry.
