LED Plant Lighting Market Status And Development Trend

- Jul 18, 2019-

  At present, agricultural lighting is applied in microalgae cultivation of microorganisms, cultivation of edible fungi, poultry breeding, aquaculture, conservation of crustacean pets, and plant cultivation, which is the most widely used. More and more fields are applied. Especially plant lighting, after the introduction of plant plant technology, has entered a stage of rapid development.

1. Types of plant lights

  At present, plant lighting types mainly incandescent lamp, halogen lamp, fluorescent lamp, high pressure sodium lamp, LED lamp. LED has obvious advantages in the field of plant lighting due to its high light efficiency, low heating, small size, long life and many other advantages, and the plant lighting will gradually give priority to LED lighting. According to a report released by smart research consulting, it is estimated that LED growth lights will account for 61% of the plant lamp market by 2020.

Ii. LED plant lighting market status and development trend

  At present, the plant lighting market is mainly concentrated in the Middle East, the United States, Japan, China, Canada, the Netherlands, Vietnam, Russia, South Korea and other regions.

Iii. Application field of plant lighting

  The field of plant lighting is one of the fields of agricultural lighting which has developed rapidly in recent years. Light plays an important role in the growth and development of plants from two aspects. One is to participate in the photosynthesis of plants as energy to promote the accumulation of plant energy; the other is to regulate the growth and development of plants as signals, such as the growth of germination, flowering and stem. From this perspective, plant lighting can be divided into growth lighting and signal lighting, while growth lighting can be divided into full artificial light growth lamp and supplementary light lamp. Signal lighting can also be divided into accelerating lamp, flowering lamp, colored lamp and so on. To distinguish from the field of application, the field of plant lighting mainly includes seedling (including tissue culture seedling and seed seedling), horticulture landscape, plant factory, greenhouse planting and so on.

Technical requirements of plant lighting users

  Plant lighting is a comprehensive and cross-domain industry, and the growth of plants is the result of multiple factors. The technical requirements of plant lighting users are not only concerned with lighting, but also include other factors. The technical requirements of plant lighting users will be analyzed from two perspectives below. They are :(1) technical requirements from the perspective of patent layout. To some extent, the patent layout reflects the judgment of enterprises, scientific research institutes and experts on technology development, so as to reflect the technical demand and demand trend of plant lighting users to some extent. (2) technical requirements from the perspective of users.

2. Technical requirements from the user's perspective

  The acceptance of plant lighting users to the industry has greatly affected the development of the industry. For the users of plant lighting, the investment cost and use cost are the key issues.

2. 1. Technical requirements from the cost of LED plant lamps

  The cost of LED lamps is directly related to the investment cost of users. Although LED lamps have obvious energy saving advantages and spectral advantages, compared with other plant lighting lamps, the price of LED lamps is relatively high. In the cost of lamps and lanterns, in addition to the shell of the lamp, driving cost, the cost of lamp beads compared with the ordinary lamp beads, the price is expensive.

2. 2. Technical requirements from the use cost of LED plant lights

  Electric power cost and electric power performance are basically concerns of every plant lamp user. Electric power performance refers to the ratio of electric power input and output per unit of consumption. The output here refers to both output and quality.

2. 2. 1 light

  As one of the main factors affecting plant growth and development, light spectrum, light intensity and photoperiod affect plant growth and development. Light efficiency is closely related to electricity performance.

(1) spectrum

  Wavelength range of 300 ~ 800 nm radiation called plant physiological active radiation (physiologically active radiation), but UVB (280-320 nm) and UVc (220-280 nm) band for plant growth and development of the secondary metabolites (produce).

(3) light effect

  Light efficiency is the ability to convert electrical energy into light energy. The higher the light efficiency, the higher the electric performance and the lower the electric cost. Plant lighting users are concerned about the overall lighting effect.

(4) the use of light

  Plant lighting, instead of sunlight, is completely controllable. The light duration, intensity and spectral variation of a day are all controllable. How to improve power performance by controlling how light is used is a concern of most plant lighting users. Total photosynthetic radiation (DLI) refers to the amount of light a plant accumulates over a 24-hour period per unit area (per square meter). Plant lighting users, especially plant factory users, pay more attention to the "saturation value" of the total amount of photosynthetic radiation of plants, so as to avoid the waste of light energy and electrical energy.

2. 2. 2 system scheme

  The characteristics of high input and high production cost require plant plants to produce crops efficiently. Different from the traditional planting environment, the environmental factors of plant factories are completely controllable, which is the basis for the efficient production of plant factories. At present, the industry mainly from intelligent management system, expert planting technology, automatic operation platform to achieve efficient production plant.

2. 2. 3 other.

  In addition, plant lighting users also have corresponding technical requirements on the use of waterproof grade, luminous Angle, heat dissipation system, lamp life, spectral effective life and light decay.
