At present, agricultural lighting is applied in the cultivation of microalgae in microorganisms, cultivation of edible fungi, poultry farming, aquaculture, maintenance of crustacean pets, and the most widely used plant planting, with an increasing number of application fields. Especially with the introduction of plant factory technology, plant lighting has entered a stage of rapid development.
1、 Types of plant lighting fixtures
At present, the types of plant lighting mainly include incandescent lamps, halogen lamps, fluorescent lamps, high-pressure sodium lamps, and LED lamps. LED, with many advantages such as high light efficiency, low heat generation, small size, and long lifespan, has obvious advantages in the field of plant lighting. Plant lighting fixtures will gradually be dominated by LED lighting fixtures.

2、 Current Status and Development Trends of LED Plant Lighting Market
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. Since 2013, the global LED plant lighting market has entered a period of rapid development. According to LEDinside statistics, the global LED plant lighting market size was $100 million in 2014, $575 million in 2016, and is expected to grow to $1.424 billion by 2020, with an average compound annual growth rate of over 30%.

3、 Application field of plant lighting
The field of plant lighting, as one of the rapidly developing agricultural lighting fields in recent years. Light mainly plays a role in the growth and development of plants from two aspects. Firstly, it participates in photosynthesis as energy, promoting the accumulation of energy in plants. Secondly, it serves as a signal to regulate the growth and development of plants, such as germination, flowering, and stem growth. From this perspective, plant lighting can be divided into growth lighting and signal lighting, while growth lighting can be divided into fully artificial growth lights and supplementary lights based on the use of artificial light; Signal lighting can also be divided into sprouting lights, flowering lights, coloring lights, and so on. From the perspective of application fields, the field of plant lighting currently mainly includes seedling cultivation (including tissue culture and seed cultivation), horticultural landscape, plant factories, greenhouse planting, and so on.
