An urban white-collar worker came home from work, lit a light on the window, the light was shining on the pot, and the vegetables began to grow rapidly. The mystery is not the nutrition in the water, but the light in the window.
In July 2012, at the 2012 Japan Facility Horticulture and Plant Factory Exhibition, exhibitors launched LED lighting modules for greenhouse multi-layer cultivation and plant factories. For a time, LED plant lighting has become a hot spot in the industry.
At present, plant lighting is mainly used in agricultural breeding, including plant production, aquaculture, microalgae cultivation, and edible fungus production. "In addition to agricultural breeding, in fact, the current viewing of plant LED lighting is gradually entering the market." According to the prediction of Yang Deli, chairman of Shenzhen West Deli Technology Co., Ltd. (hereinafter referred to as "West Germany"), domestic breeding lighting in the next few years The LED replacement market will reach 30 billion yuan.
Despite such a good market prospect, it needs to be realized in the future for a long time.
"At present, the field of plant lighting applications is commercial, and plants enter the home and decoration field, at least five years." Yang Deli said that there are many factors limiting the domestic LED plant lighting.
According to statistics from the High-tech LED Industry Research Institute (GLII), the output value of LED plant lighting in China in 2011 was about 300 million yuan, of which more than 90% were exported. The LED plant lighting factory is currently in the Chinese market and is still in the cognitive and running-in period, and the next two to three years will be the rapid rise of the LED plant lighting market.
New entrants have a low chance of success
In 2010, the State Council issued Document No. 1 "Several Opinions of the CPC Central Committee and the State Council on Strengthening the Overall Planning of Urban and Rural Development to Further Consolidate the Basis of Agricultural and Rural Development", which clearly stated that it is necessary to actively support the transformation of agricultural development methods and improve the capacity of agricultural science and technology innovation and promotion. This paper document has also been interpreted by the major agricultural research institutes as a policy leader for the development of China's LED plant lighting industry. Many companies are targeting this market.
According to GLII statistics, as of the end of June 2012, there were about 40 LED plant lighting companies in China with a certain scale. As early as 2009, there were only two or three companies engaged in LED plant lighting in China. “China is the fourth largest plant factory in the world, and the future of LED plant lighting is promising.†An industry source said that, based on optimistic judgments on future market scenarios, the number of companies engaged in LED plant lighting has increased year by year since 2009. .
"These new entrants only see the high gross profit of LED plant lighting." In Yang Deli's view, although the current LED plant lighting gross margin exceeds 100%, there are not many successful cases. "The success rate is only a single digit."
The reason is that the current domestic market model of plant lighting is based on the cooperation between enterprises and the Academy of Agricultural Sciences, that is, the research institutes are looking for some professional LED plant lighting companies, and we jointly develop some standards for product development.
“If you do not have certain channels and resources, it is difficult for new entrants to participate in market competition. LED plant lighting involves multidisciplinary fields, including semiconductors, spectroscopy, biology, etc., and these fields are completely different industries, LED lighting companies There must be some shortcomings.†Yang Deli said that it takes at least three to five years for LED lighting companies to successfully enter the field of plant lighting.
In fact, in overseas markets, many foreign LED manufacturers have already laid out agricultural lighting, and market competition is quietly taking place. On the one hand, with the development of LED technology, governments of various countries have taken LED agricultural lighting applications as an important development direction and actively deployed. On the other hand, the strong support of the resource-scarce countries represented by Japan to the plant lighting industry is also rapidly promoting the development of the local market.
"With the improvement of agricultural environmental protection requirements, technological progress, and price decline, the plant lighting market will soon usher in a new round of growth." Taiwan's plant lighting representative company Li Lai Deng general manager You Liantian predicted that next year's plant lighting market will There is an outbreak period.
Take Li Lai Deng as an example. In 2011, the company's revenue at the plant lighting factory was NT$100 million. In the first half of this year, the company received a foreign government order of nearly NT$100 million.
When you travel or go to some remote areas, you may be annoyed by poor reception. Is there any way to get a strong WiFi router signal outdoors in a 4G LTE network? Very good, outdoor 4G CPE router would be a good choice!
What is an outdoor 4G CPE router?
An outdoor 4G CPE router differs from a Wifi-only router in that it needs to be connected to a fiber optic network. The 4G CPE WiFi router can pick up the carrier's 4G LTE network signal and convert it into broadband and Wi-Fi. Just plug in your SIM card with your data plan and enjoy a stable and reliable WiFi signal with family and friends. This Outdoor CPE can be used in harsh environments.

Second, what are the characteristics of outdoor 4G CPE router?
1. Better network for ODU and IDU
4G CPE outdoor routers include an outdoor unit (ODU) and an indoor unit (IDU). Help your device receive the best outdoor cellular signal through the ODU, and connect to the indoor WiFi router through the network cable to experience better network speed. As shown in the figure below, an outdoor LTE CPE (ODU) is installed outdoors and connected to an indoor Wi-Fi router (IDU) via a network cable. The entire 4G device is powered by POE. This data will be transmitted over the same Ethernet cable, eliminating the need to connect the ODU to a power outlet.
2. High-speed multi-user available
The outdoor 4G CPE features a built-in 4G LTE modem and a 5dBi high-gain antenna. LTE CAT4, download speeds up to 150Mbps, WiFi speeds up to 300Mbps, can connect 32 users at the same time. The high-gain antenna of the outdoor 4G CPE router enables it to have higher power and stronger signal transmission and reception capabilities than mobile phones. Therefore, the CPE router can receive the signal. If your phone can't receive a signal in some areas. Sometimes you also use your phone as a hotspot to share Internet access with your friends, right? Similarly, this 4G LTE CPE router allows 32 users to connect to WiFi at the same time, allowing more users to connect and receive a better signal than a phone sharing hotspot. In addition, the IDU has four Lan ports and can be connected to the device through network cables, which is also a backup mode of the Internet.
3. Excellent outdoor performance and design
