Six technological trends in the LED lighting industry

While the real economy continues to decline, the LED industry has experienced a jaw-dropping development. The entire industry has doubled its growth in the past few years and has become the world's most beautiful "potential stock" in one fell swoop.

Aside from the terminal siege wars of many manufacturers, the development momentum in various fields such as deep ultraviolet, small pitch, backlight, flip-chip, strong packaging, large heat dissipation, small drive, intelligent control, phosphor, silica gel, etc. is also encouraged. The more capital is added to the "LED Industry Army".

In the future, the LED industry will further increase the degree of industry concentration, and advantageous resources will move closer to advantageous led lighting companies. At the same time of the feast, we also have to think deeply about the dazzling array of LED products with serious homogeneity, uneven product prices and fierce competition. How can companies find new outlets?

The new technology is secretly exerting force, the LED market competition is increasingly fierce, the prospects for LED innovation and application are attractive, the LED intelligent lighting is emerging, and the LED industry is on the way.

First, the chip and packaging links are developing rapidly. Light efficiency is improving, and technologies such as flip chip, high-voltage chip, COB, EMC, and CSP packaging are all developing. All domestic and foreign device products have begun to combine light source module component products, especially IC integration products, system integration, and modularization. COB devices below 30W are still the mainstream products in the market, and there may be substantial growth in the future.

Secondly, although device manufacturers have made the sound of researching and developing CSP and flip-chip non-gold wire packaging in the past two years, they have finally become popular this year. There are already CSP products for direct-lit backlights and TV display products. For example, CSP packaging products imitate the COB form, multiple small devices are combined in series, and can be assembled infinitely according to the size of the application. In addition, the market for phosphor products related to high CRI is outstanding this year.

Third, high-power high bay lights and floodlights made of EMC device products imitating integrated packaging modes are gradually gaining popularity. With the development of modularized automotive lighting, the market is stable and needs to be expanded. For example, automotive headlights and turn signals are the most attractive market cake.

Fourth, intelligent lighting solutions for lamps, intelligent solutions for homes and commercial places, etc. have become the market. Intelligent lighting is becoming more and more popular, which is a trend and a challenge. The current "App+lights+control system" approach, each product is self-contained from lights to software, and systems. There is no unified standard or protocol, and interconnection is impossible. This is A major drawback that restricts development.

Fifth, filament lamps are more mature. Many companies rely on technology to produce and sell in various countries around the world. The market is booming. Sapphire substrate filaments have become the main products to replace old-fashioned filament lamps.

Sixth, there are more and more UV LED light applications, plant lighting applications, etc., and the penetration rate is getting higher and higher. For example, UV LEDs are used in security, disinfection, curing and other fields. The potential market for these LED segments is huge, but they all need large-scale applications to further tap market opportunities.

Today, the advantages of chip packaging technology are emerging, industrial equipment is rapidly expanding, the display field is extended, and smart lighting is gradually becoming the trend. The scale of market segments such as plant lighting, medical lighting, and agricultural lighting is also gradually expanding, and has been paid attention to by the industry.

In short, all kinds of new products for this feast of LED lighting have swarmed, and the new lighting ecosystem is quietly reshaping.
