Fluorescent grow lamp market
By 2020, the global fluorescent lamp grow lamp market is expected to reach 1 billion U.S. dollars, and such products are very popular with home gardeners. Standard fluorescent lamps are usually used for seed germination, but the efficiency is not high. In order to overcome the shortcomings of standard fluorescent lamps, advanced technology will cooperate to produce high-yield and efficient fluorescent lamps. Compared with standard fluorescent lamps, the newly developed fluorescent lamps have stronger light but lower temperature. Such products are more effective and cost-effective than incandescent lamps.
In addition, the fluorescent lamp bracket will also be lighter and easier to install, making it more convenient for users to use, and the bulb can be replaced at any time.
High pressure sodium lamp growth lamp market
By 2020, the global market value of high pressure sodium lamp growth lamps is expected to reach 157 million U.S. dollars. The orange and red light from high-pressure sodium lamps can make flowers produce, bear fruit, and ripen, and they can provide sufficient lighting for the greenhouse. The advantage of the high-pressure sodium lamp is that the irradiation range is wide, and the high-pressure sodium lamp should not be too close to the plants, because it will generate a lot of heat. But the greenhouse does need more heat in winter. After the high pressure sodium lamp is used for a long time, the irradiation will become weak, and it needs to be replaced. The average life span of such lamps is 18,000 hours.
According to Technavio Agricultural Equipment Analyst Abhay Sinha, “High-pressure sodium lamps have the highest efficiency among all high-intensity gas discharge lamps. The luminous efficiency of high-pressure sodium lamps is 6 times higher than that of incandescent lamps. Conducive to promoting the growth of the indoor cultivation industry."
Incandescent lamp and halogen lamp growth lamp market
The global incandescent lamp and halogen lamp growth lamp market value will reach 79.5 million US dollars by 2020, with a compound annual decline rate of 1.5%.
Incandescent lamps are usually available in grocery stores and hardware stores, but one disadvantage of using incandescent lamps as growth lamps is that they do not save energy. The part of the energy that does not produce light will generate extra heat. Abhay said: "Although I just started buying incandescent lamps The cost is very low, but the operating cost is higher than that of fluorescent lamps. Therefore, it is not suitable to use incandescent lamps as growth lamps, and so are halogen lamps, because their performance is similar to that of incandescent lamps."
The difference between LED plant growth lamps and high-pressure sodium lamps in horticulture production, the difference between LED plant growth lamps and high-pressure sodium lamps in horticultural production, in the future to meet the growing demand for food, a relatively closed production system such as greenhouses will play an important role. In recent years, the lack of sunlight in greenhouses has attracted more and more attention. On the one hand, the light transmittance of the greenhouse is reduced due to the orientation, structure, and covering material characteristics of the greenhouse, and on the other hand, the lack of sunlight in greenhouse crops caused by climate change. , Such as continuous rainy weather in winter and early spring, frequent haze weather, etc. Insufficient sunlight directly adversely affects greenhouse crops, causing serious losses to production.
Plant fill light can effectively alleviate or solve these problems. Incandescent lamps, fluorescent lamps, metal halide lamps, high-pressure sodium lamps and emerging LED plant growth lamps have been or are being used in greenhouse lighting. Among these types of light sources, high-pressure sodium lamps have higher luminous efficiency, longer service life, and higher overall energy efficiency, and occupy a certain market position. However, high-pressure sodium lamps have poor lighting durability and low safety (containing mercury). Problems such as not being able to illuminate at close range are also prominent.
