Analysis on the development prospects of China's led growth lamps and the difficulties they face
At present, in Japan and Taiwan, the planting of LED plant lights has become very common. A friend in Taiwan introduced that the current cultivation of vegetables in the LED city is already a normal project in Taiwan. And because of a whole set of hydroponic experience, the benefits have been higher than traditional planting. Although the mainland China is not an LED plant lamp and hydroponics is the starting point. However, relying on its own manufacturing advantages, most of the current LED plant lights are exported from China.
Led growth lights business opportunities unlimited
As a special type of semiconductor material, the wavelength of light emitted by the LED can range from ultraviolet C (~250 nm) to infrared (~1000 nm), and the wavelength range of light emitted by each LED can be narrow. Thus, it is a very efficient plant illumination source with true spectrum control capabilities.
Unlike metal halide light sources, fluorescent lamps, and high pressure sodium lamps, the solid state lighting systems used in LEDs have some unique advantages. They are not only light in weight, small in size, long in service life, but also have the advantages of controllable wavelength and spectral composition, narrow bandwidth, low luminous surface temperature, low heat generation, high brightness, low radiation and high efficiency. In addition, LEDs also have the characteristics of spectral control. With the continuous advancement of technology and the continuous improvement of the technological level, the spectral control of LEDs will be more flexible in the future, and the manufacturing and use costs will be lower and lower, and its superiority will be more fully reflected.
These advantages also make LEDs gradually replace the status of traditional lighting sources. In plant lighting, LEDs can match the appropriate range of light waves to the plant's light receiver and affect the shape and composition of the plant. For plants grown in a controlled environment, the superiority of LEDs also makes them the preferred source of light.
It is understood that the global LED application plant lighting output value has started to show rapid growth since 2013. The preliminary statistics reached US$100 million in 2014 and is expected to reach US$500 million in 2017. With the increase in the penetration rate of global LED application agricultural lighting, the Chinese market is slowly emerging, and the future market prospect is broad.
The new blue sea of led growth lights has also attracted the development of a large number of international giants. After the establishment of plant lighting factory by Philips LED, international giants such as OSRAM, Mitsubishi, GE and Siemens have also made some moves in this field; Taiwan factory Yiguang is also early There is involvement, and with the rise of Taiwan’s agricultural gold boom, there are reports that “Taiwan’s technology giants Hon Hai, Delta, Jinrenbao Group, Xinxing Electronics and the old Datong Group have also started to grow vegetables across the line”; In terms of manufacturers, Qinshang Optoelectronics, Hongli Optoelectronics, and Guangmingyuan have been conducting research and development of related products.
When it comes to plant lighting, most of the accompanying words are “foreground”, “money scene” and “future”. However, what problems exist in the current development of plant lighting?
Plant lighting invention faces many problems to be solved
At present, the development of domestic plant lighting is slow, and the market development space is still limited. The domestic LED growth lamps are also faced with the problems of lack of comprehensive talents, high cost investment, lack of patents, and low output rate of enterprises. When the development of plant lighting in China enters the fast lane is still a problem.
Low input-output ratio
As an emerging market, plant lighting has a low market penetration rate. Compared with the output value of hundreds of billions of ordinary lighting, it can only be described as “a small house”. At present, the sales market of LED plant lights in China is mainly concentrated in countries and regions with less agricultural personnel such as Japan, South Korea, Central America and Europe.
