Analysis of the technical needs of plant lighting manufacturers

Plant lighting fixtures are a type of lamps based on application objects. Its irradiation objects are plants, and they are expected to have an expected physiological response effect.

Light is both energy source and signal source for plants. As an energy source, light provides energy for the photosynthesis of the plant, and provides heat to plants; as a signal source, light affects the optical, light formation, physiological cycle, secondary metabolites, and influence of air pores. Through artificial light supplementation or all artificial light, the plant can make plants grow faster, make seedlings shorter, can control the flowering period of the plant, can make plants more flowers, more beautiful colors, more fruits, can enhance the plant’s effective use of ingredients can reduce the occurrence of pests and insect pests, and other goals we expect to achieve.

The goal -oriented -oriented creates the appropriate plant light environment, and the parameters include: light quality, photon density, light direction and light cycle. Light, which is spectrum. The spectrum required by plants is composed of a spectrum emitted by one or more LED components. LED components are divided into two categories, one is fluorescent powder conversion LED. It is obtained by stimulating one or more fluorescent powder by blue light or purple -light chip, and the other is the LED chip directly transmits a narrow wavelength spectrum directly. At present, most plant LED packaging companies can provide fluorescent spectrum customization services for plant lamp companies, and can also provide narrow spectrum LEDs from 365nm to 740nm. Lantern manufacturers obtain the required plant lighting light quality by combining a variety of LEDs. The figure below is the optical customization service provided by plant lighting manufacturers to customers.

For photon density and light direction, the lamps can be designed as “points, lines, and faces” as elements, and the space is discharged, and an optical reflex or lens that is designed with professional design can be added. The direction of light required. For example, the “dot” light source method of the dragon fruit flowering period is suspended on the dragon fruit stem branch of the dragon fruit stem. Light vegetable plant factory is placed on the top of each layer with a “surface” method of light source panel.

The light cycle (including frequency, timing, and strength -free adjustment) is mainly implemented through power design and software and hardware system control.

Plant lighting lamps generally need to be used continuously for a long time. Due to the diverse application environment of the lamps, the characteristics of the characteristics of the application occasion should be combined with the characteristics of comprehensive design and protection. At least the following factors need to be considered:
A. Daily use daily;
B. Environmental UV intensity;
c. Environmental temperature;
D. Environmental humidity and potential liquid distribution;
E. Electricity environment;
F. Temperature change rate;
G. Biological environment;
H. Air salt and fog;
I. Environmental vibration;

It should be noted that in terms of gradient failure standards, the standard of life -to -life calculation should be greater than 90 % in order to ensure the stable use of the planting system.

Research on plant lighting enterprises, products and customer distribution

LISUN interviewed 20 international and domestic mainstream LED packaging companies and main plant lighting packaging companies to learn about their current business situation in the plant lighting market and their views on plant lighting. After the preliminary interview, LISUN preferably 10 of the representative light source packaging companies conducted again and again. These 10 companies are: OSRAM, Lumileds, Samsung, Luminus, Edision, SHINEON, HONGLI, REFOND, SUNPU, SUNPU, Lide SUNPU, SUNPU, LEDSTAR. And some of these company already purchased LISUN LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters.

(1) The market participation of LED plant lighting beads packaging enterprises
Most international and domestic mainstream packaging manufacturers know and are closely concerned about the progress of the plant lighting market. After interviewing 20 packaging companies, the author learned that because the current volume of plant lighting markets is still small, there are three strategies for the plant lighting market: there are three types of strategies:

1. Continue to wait and see, the plant lighting bead products have not yet been released;
2. Although plant lighting products have been released, it has not actually promoted the energy;
3. Not only have plant lighting products, but also strive to strive for greater market share.

In addition to the mainstream packaging companies, the current participation in plant lamp beads also includes a number of small and medium -sized packaging factories or professional plant lighting lamp manufacturers. These companies are mainly distributed in Shenzhen, Dongguan and Zhongshan in Guangdong.

The author has statistics on the time of the 10 plant lamp packaging companies in key interviews entering the market. Osram is the earliest company to supply special lamps for plant lighting. In 2014 and before, 4 of these 10 packaging companies have released plant lighting beads in the plant lighting market. Lighting, and more people recognize that Japan and the United States’ artificial light plant factories, especially the United States, are legalized through marijuana planting in many states. In 2016, more leading packaging companies have released the lamp beads of plant lighting one after another packaging products.

(2) The technical situation of the product technology of LED plant lighting beads
A. Spectral analysis
LED plant lighting light source spectral spectrals are divided into two categories. One is the narrow spectrum emitted by the chip itself, and the other is the fluorescent conversion spectrum of fluorescent powder with blue -purple light chips. The following are the chip narrow spectrum provided by the packaging company, and the statistics of the number of LED spectrals developed by the packaging manufacturer for customers.

It can be seen that in terms of narrow wavelength LED products, most packaging suppliers can provide customers with various wavelength products from 365nm -740nm. In terms of fluorescent powder transformation, most packaging manufacturers have a variety of spectrals for customers to choose from. Although there are many types of fluorescent transformation spectras for customers to choose from, the actual spectral styles of the actual shipment are very concentrated.

B. Power analysis
The encapsulation form of LED plant lighting light sources follows the form of traditional lighting. The packaging form can be divided into four categories:
1. 0.2-0.9W 2835 and 5730 packaging;
2. 1-3W high -power EMC bracket packaging, imitation packing packaging or ceramic lining lens package;
3. 3-10W COB packaging or large ceramic SMD packaging;
4. ＞ 10W COB packaging.

The following is the statistics of the LED light source power that can be supplied by each packaging company.
As can be seen from the figure above, all packaging companies can provide universal packaging products of 0.2-0.9W and 1-3W. These light sources give lamp manufacturers very good flexibility during lamp design. In addition, some manufacturers also provide higher power integrated packaging products. At present, more than 80 % of the 10 manufacturers are 0.2-0.9W or 1-3W. Among them, the international leading packaging companies are concentrated in 1-3W, while the shipments of small and medium -sized packaging companies are concentrated in 0.2-0.9W.

(3) Plant lighting lamps and corporate regional distribution, lamp application regional distribution:
From 10 interviewed plant lighting packaging companies, it is learned that the current global plant lighting lamp production customers are mainly distributed in China (including Hong Kong, Macao and Taiwan), North America, Europe, Japan, and other regions. It is Europe or North America, and a few packaging companies are mainly Europe or North America.

The application areas of plant lamps include China (including Hong Kong, Macao and Taiwan), North America, Europe, Japan, Middle East, South America, Australia, Singapore. The customer groups of various packaging manufacturers are very different. The proportion of applications is very different. In summary, lamps used in North America, mainland China and Europe account for about 20-40 %, respectively.

(4) Field of plant lighting lamps
From the perspective of application, plant lighting fixtures are mainly used in artificial light marijuana planting, sunlight greenhouse supplement, all -artificial light plant, plant tissue cultivation, dragon fruit supplementation, family vegetables and flower planting, and laboratory research. The proportion of packaging manufacturer’s client for application fields is shown in the figure below.

Among them, artificial light marijuana planting applications account for about 20 %, solar greenhouse applications account for 20-40 %, and the application of all artificial optical plant factories accounts for about 20-30 % of Plant factory. We also confirm the market application from plant packaging light sources.

(5) Market and future prediction of plant lighting
From the 10 plant lamp packaging companies, it is learned that whether the 660nm LED light source or the fluorescent powder conversion plant LED light source, their 2017 sales growth rate in 2016 recorded a significant increase, of which the growth rate of 660NMLED light sources concentrated on the growth rate of light sources. In 20-50 %, the sales growth rate of fluorescent powder conversion plant LED light sources reached 50 % -200 %, and the sales of fluorescent powder conversion plant LED light sources increased faster.

Packaging companies generally hold an optimistic attitude towards the development of plant lighting beads in the future. The expectations of growth rates in the next three years are concentrated at 20-50 %. Therefore, in order to better serve the market, 9 of the 10 from the 10companies were launched new plant lighting products in 2018.
