With the LED display used in the rental market, HDR market applications, retail department stores, conference room market demand increases, its market size is growing.
China's LED display market will reach 52 billion yuan in 2018, up 15 percent, according to OFweek industry research institute.
From the perspective of industrial structure, LED display has also gradually changed. Manufacturers, market channel sellers, engineering installation and after-sales service operators and other specialized enterprises focusing on display production have emerged. The professional division of labor in the industry is taking shape, and a situation of clear division of labor, close cooperation and win-win development will emerge.
Under the situation of continuous technological innovation, falling price and huge potential market, LED display screen will be more widely used. Not only in public life and commercial activities, but also with the development of smart home, smart display and other demands, it will permeate into all aspects of people's life.
Driven by this, LED display industry will get more opportunities to maintain a good momentum of vigorous development.
However, when the surface of the industry is booming, many enterprises also feel a hidden "cold current" is surging under.
As we all know, the LED display industry from the lowly, is relatively "barbaric" growth way, the LED display industry develop very fast, but in the industrial market scale growth at the same time, low brand share, structural overcapacity, industry products, such as after-sales difficult also became the outstanding problem of restricting its development, at the same time, "heavy light products, service" of the traditional thought is deeply rooted.
However, how can LED display enterprises solve these problems and achieve further development?
LED landscape lighting
With the rapid development of urban economy and the improvement of people's aesthetic consciousness, urban landscape lighting has become an indispensable part of urban planning.
To a certain extent, urban nightview lighting has become a window to show the image of the city and a symbol to measure the overall development level of the city.
As an important part of urban planning and construction, it not only reflects the economic prosperity of a city, but also reflects the cultural temperament and civilization of the city.
With the continuous excavation of the value of urban landscape lighting in China, the scale of landscape lighting project has been gradually expanded, and the industry has ushered in a rare opportunity for development.
China's LED landscape lighting market will reach 75 billion yuan in 2018, up 20.7 percent, according to OFweek industry research institute.
In recent years, the high gross profit market segment is favored, one of the areas is landscape lighting, because of its huge development potential, many enterprises in the industry have rushed to attack.
Dou linping, secretary-general of the China lighting society, said the demand for lighting design in key cities has already entered the fast lane.
With the deepening integration and common development of "smart city" construction and "beautiful China", and the implementation of a series of national policies on energy conservation and ecological and environmental protection, the demand for landscape lighting continues to increase, and the lighting market is more segmented.
A large number of large-scale urban landscape lighting demonstration projects have emerged nationwide, and local governments have increased their investment in landscape lighting, which will usher in new opportunities for urban landscape lighting.
Because the landscape lighting industry has certain restrictions in talent, capital and technology, lighting enterprises need to provide customers with the service of the complete industrial chain of landscape lighting, and at the same time actively promote the technological innovation of the industrial chain, promote the integration and development of each link, so that enterprises can win the opportunity in the landscape lighting market.
According to OFweek industry research institute, the global UV LED market is worth $300 million in 2018, with a growth rate of 30.4%.
Between 2008 and 2018, the number of UV LED enterprises increased from 10 to 65.
Since 2010, several visible LED companies have turned to ultraviolet leds in search of new growth drivers and higher profits.
The UVA segment of the UV spectrum was the first market segment to see significant price cuts as companies expanded production and more companies entered the market.
The dramatic drop in UVA LED prices further accelerated the adoption of the technology.
Now, following LG Innotek's price cut, Epileds Technologies, a Taiwanese maker of LED epitaxial chips and chips, is making similar moves.
As a result, the price of uv-aled chips has decreased by 15-20% in the first half of 2018. In the future, only companies that can innovate in UVA LED and uv-curing will be able to sustain profitability.
The UVB and UVC parts of the UV spectrum are more difficult to develop in terms of performance.
Compared with visible LED, UV LED research and development has three major problems, namely epitaxial growth equipment, chip materials, LED packaging.
UV leds have higher requirements for MOCVD uniformity and temperature tolerance, and the epitaxial growth conditions of visible leds are not applicable.
Previous blue leds used gallium nitride or indium gallium nitrogen as the substrate, while UV leds used aluminum gallium nitrogen as the substrate, the lattice defects and adaptation of the two are not the same, need to be re-studied.
And the packaging system is also very different from the traditional packaging, also need to re - research and development.
As a result, UVB and UVC leds require more expensive and time-consuming development, leading to a much higher threshold for new UVB and UVC LED manufacturers.
For this reason, the UVB/UVC market is growing much more slowly.
UV LED manufacturers have a different strategy, depending on the wavelength of their target product.
While some manufacturers continue to focus on device manufacturing, others are beginning to vertically integrate module and system production.
In addition to UV LED manufacturers, a number of new entrants, mainly at module and system levels, are also trying to enter the industry.
The IR leds
IRLED, namely infrared LED, is a near-infrared light-emitting device that converts electric energy into light energy. It has a series of advantages such as small size, low power consumption and good directivity.
According to the characteristics of IRLED chip, infrared LED products with different wavelengths can be applied to different fields, such as remote control, medical instruments, space optical communication, infrared lighting, pump source of solid laser, automatic card swipe system of highway, camera, monitoring, building interphone, burglar alarm, etc.
With the rise of modern Internet of things, biometrics and wearable devices, various sensors and image identification technologies are becoming more and more important.
IRLED application characteristics, become an important auxiliary light source.
And by combining the sensing device with the recognition technology, it can be applied to iris recognition, face recognition and other special applications.
Or it could be applied to biosensors in wearable devices, which can quantify the physiological state of the human body and become a new tool for health management.
The asia-pacific region will become the world's largest market segment for infrared leds, given the surge in penetration of smartphones, cars, surveillance systems and other infrared LED applications.
The global UV LED market is worth $910 million in 2018, up 51.7 percent, according to OFweek industry research institute.
More than 40 applications have been integrated with infrared solid-state light sources.
Some of these applications are expected to fuel the IR LED market in the next five years!
LED plant lighting
With the continuous development of modern agriculture, the demand and energy consumption of plant lighting are constantly expanding, posing new challenges to the traditional plant lighting technology.
As a new generation of light source, LED besides the characteristics of energy saving and environmental protection, compared with the traditional agricultural field commonly used fluorescent lamp or high pressure sodium lamp light source, with the spectrum can be freely combined, high purity color, rich color and other advantages.
According to meyer-brenken, osram's plant lighting business development specialist, LED technology has lower power consumption than traditional plant lighting technology and can save a lot of energy costs.
LED based plant lighting solutions can help growers achieve both yield demand and sustainability goals by helping growers increase yields by 25% and reduce energy costs by 50%.
Special lighting configuration can not only optimize yield and growth time, but also improve the nutrients contained in crops and improve their taste and flavor.
It can be seen that LED plant lighting can be designed into various types of light sources according to different plant species, purposes and needs, and the required spectrum can be precisely controlled. It is suitable for plant factories with various modes and types of irradiation, which cannot be achieved by traditional light sources.
With the continuous improvement of LED plant lighting technology, its application field will be more and more extensive, including the top floor of skyscrapers, vertical farms, greenhouses, homes, shopping malls, and even abandoned containers, etc., can develop plant lighting.
According to OFweek industry research institute, the global LED plant lighting market is worth $190 million in 2018, with a growth rate of 26.7 percent.
According to the estimation of the scale of China's existing agricultural industry, in the next five years, the demand for agricultural LED lighting and its control equipment will reach several billion yuan. The plant plant and greenhouse lighting supplement will be the fastest developing LED lighting field with high technology content and strong intelligent and systematic equipment, which is the focus of the development of agricultural semiconductor lighting industry.
It can be seen that with the improvement of global LED application agricultural lighting penetration rate, the future market prospect is broad.
