With the continuous development of modern agriculture, the demand and energy consumption of plant lighting is expanding, which poses new challenges to traditional plant lighting technology.
As a new generation of light source, in addition to the characteristics of environmental protection and energy conservation, compared with artificial light sources such as fluorescent lamps or high-pressure sodium lamps commonly used in traditional agricultural fields, LED has the characteristics of adjustable light quantity, adjustable light quality, low cooling load, and allowed to increase the cultivation amount per unit area.
It is a suitable closed agricultural production environment, such as a plant tissue culture room.
Under the influence of the objective environment with fierce competition in the general lighting market and increasingly prominent environmental and health issues, the application of plant lighting has gradually become one of the development directions of LED. Lighting giants have already begun to lay out the LED plant lighting business.
Following the establishment of plant lighting plants by Philips LED OSRAM, Yiguang and other enterprises also took action in this field.
In addition, many domestic enterprises are also involved. Recently, Lavi, a subsidiary of Guangmingyuan, opened the largest plant factory in South China to research, develop and produce plant growth lights with different needs; Qinshang Optoelectronics also launched new intelligent products with plant lighting functions. The development of LED plant lighting has broad market prospects.

Recently, Lavi, a subsidiary of Guangmingyuan, opened the largest plant factory in South China to research, develop and produce plant growth lights with different needs; Qinshang Optoelectronics also launched new intelligent products with plant lighting functions. The development of LED plant lighting has broad market prospects.
As a particular type of semiconductor material, LED can emit light in a wide range from ultraviolet C (~250nm) to infrared (~1000nm), and the wavelength range of light emitted by LED in each wide range can be very narrow.
Therefore, it is a very effective plant lighting source with real spectrum control capability.
Unlike metal halide light sources, fluorescent lamps, and high-pressure sodium lamps, LED solid-state lighting systems have some unique advantages.
They are not only light in weight, but small in size, and long in service life. But also have the advantages of controllable wavelength and spectral composition, narrow bandwidth, low luminous temperature, low heating, high brightness, low radiation, and high efficiency.
It also has spectral adjustability.
With the continuous progress of technology and the continuous improvement of process level, LED spectrum control will be more flexible in the future, its manufacturing and use costs will be lower and lower, and its advantages will be more fully reflected.
These advantages also enable LED to gradually replace the position of traditional lighting sources in plant lighting. LED can match the appropriate light wave range with the light receiver of plants, affecting the shape and composition of plants.
In a controlled environment for plants grown, LED’s advantages also make it the first choice for light sources.
It is understood that the output value of applied plant lighting has been growing rapidly since 2013.
According to preliminary statistics, it reached US $100 million in 2014 and US $500 million in 2017.
With the increase in the penetration rate of agricultural lighting, the Chinese market is also slowly rising, and the future market prospects are broad.
LED After Philips, the new blue sea of plant lighting has also attracted the development of copious international giants.
After LED Osram and Mitsubishi plant lighting plants establish, GE, Siemens, and other international giants have taken action in this field.
Taiwan factories have been involved for a long time.
With the rise of Taiwan’s agricultural gold trend, it is reported that Taiwan’s technology giants Honghai, Taida Power, Jinrenbao Group, Xinxing Electronics, and Laodatong Group also grow vegetables across the industry.
For mainland manufacturers, Diligent Optoelectronics, Hongli Optoelectronics, and Guangmingyuan are also developing related products.
When it comes to planting lighting, most words are associated with prospect, money, and future.
However, what problems exist in the current development of plant lighting?
China’s plant lighting is developing slowly, and the market development space is still limited. China’s LED plant lighting is also facing problems such as a shortage of comprehensive talents, high-cost investment, shortage of patents, and low enterprise output rate.
Whether the development of Chinese plant lighting will enter the fast lane is still a question.
As an emerging market, the market penetration rate of plant lighting is low. Compared with the output value of hundreds of billions of ordinary lighting, it can only be described as a hut.
The sales market of LED plant lights in China is mainly concentrated in Japan, South Korea, China, the United States, Europe, and other countries and regions with fewer agricultural personnel.
Plant lighting is mainly used in three fields: plant factory, landscape, and breeding lighting.
At present, the chief market for plant lighting is plant factories.
American scientists plan to build skyscrapers for plant factories.
It is said that only five buildings can meet the needs of millions of people.
Although the aquaculture lighting market has great potential, the market has not yet developed. Farming lighting is mainly used for LED, but the biggest difficulty in promotion is the change of cognition.
In addition to Philips, Osram, Mitsubishi, Evian, and other international lighting factories are still paying attention to this market.
Most domestic small and medium-sized lighting companies seldom participate.
At the same time, the input and output of plant lighting at the current stage are not in direct proportion, which also makes a large number of enterprises coveting this market segment stop quickly.
Mitsubishi’s investment in LED plant lighting is about ten times that of ordinary plant lighting. The price of such vegetables in the market is four times that of general vegetables.
