In modern agricultural production, plant growth lamps are widely used in greenhouse planting, vertical farms, indoor gardening and other scenarios. Its cost mainly includes initial investment cost and long-term operating cost. The initial investment cost includes the purchase cost of lamps and installation costs, etc.; the long-term operating cost mainly includes electricity costs, maintenance costs, etc.

1. Comparison of initial investment cost and long-term operating cost

Initial investment cost

Lamp purchase cost: The price of LED plant growth lamps varies depending on factors such as brand, model, and power. Generally speaking, high-quality LED plant growth lamps are relatively expensive, but their performance and service life are more guaranteed. For example, some medium-power LED plant growth lamps range from a few hundred yuan to thousands of yuan, while high-power commercial-grade LED plant growth lamps may cost thousands or even tens of thousands of yuan.

Installation cost: The installation cost varies depending on the installation method and location. If it is installed in an existing greenhouse or indoor planting space, and the lamp has a convenient installation design such as plug-and-play, the installation cost is relatively low, and may only require simple tools and a small amount of labor costs. However, if complex wiring, bracket installation, etc. are required, the installation cost will increase accordingly.

Long-term operating costs

Electricity costs: The power consumption of LED plant growth lights is a key factor affecting the electricity cost. Its power consumption is proportional to the power and usage time of the lamp. For example, an 800W LED plant growth lamp consumes 0.8 kWh per hour. Assuming that the electricity cost is 0.6 yuan/kWh and it is used for 12 hours a day, the daily electricity cost is 0.8×12×0.6=5.76 yuan. In addition, the electricity fee standards in different regions are different, and there are also differences in the electricity prices for commercial and residential electricity, which will lead to changes in electricity costs.

Maintenance costs: The service life of LED plant growth lights is generally long, usually up to 50,000 hours or more. Under normal use, the maintenance cost is relatively low, mainly including occasional lamp cleaning, parts replacement, etc. However, if the lamp quality is poor or the use environment is harsh, the maintenance cost may increase.

2. Cost structure optimization method

Choose high-quality lamps

Although the initial investment cost of high-quality LED plant growth lamps is high, they have higher light efficiency, longer service life and more stable performance. In the long run, it can reduce electricity bills and maintenance costs and improve economic benefits. For example, some energy-efficient LED plant growth lamps can achieve a light efficiency of 2.8μmol/J or even higher, which can save more electricity than ordinary lamps under the same lighting effect.

Reasonable design of lighting system

According to the size and shape of the planting space and the growth needs of the plants, the layout of the lighting system and the number of lamps should be reasonably designed to avoid insufficient or excessive lighting. At the same time, choose lamps with a suitable spectrum to improve the utilization rate of light energy. For example, for most plants, red light and blue light are the main spectra of photosynthesis. Choosing LED plant growth lamps with a suitable ratio of red and blue light can better promote plant growth and reduce energy waste.

Use intelligent control system

The intelligent control system can automatically adjust the light intensity and spectrum according to the growth stage and environmental conditions of the plants. This can not only meet the lighting needs of plants in different growth periods, but also avoid unnecessary energy consumption. For example, through the intelligent dimming function, an appropriate proportion of blue light is provided during the vegetative growth stage of the plant to promote leaf growth, and the proportion of red light is increased during the flowering period to promote flower bud differentiation and flowering, thereby increasing yield and quality while reducing operating costs.

Optimize the planting environment

A good planting environment can improve the efficiency of plant utilization of light and reduce energy waste. For example, keep the planting space clean and ventilated to avoid dust covering the lamps and plant leaves to affect the lighting effect; reasonably control the temperature and humidity to avoid excessively high or low temperature and humidity from adversely affecting plant growth and lamp performance, thereby reducing energy consumption and maintenance costs.

Utilize preferential policies and energy-saving technologies

Pay attention to the preferential policies of local governments and relevant departments, such as subsidies for energy-saving products and agricultural support policies, to reduce initial investment costs. At the same time, the use of energy-saving technologies, such as using off-peak electricity for lighting and installing solar photovoltaic power generation systems, can further reduce electricity costs.

In short, there is a certain relationship between the initial investment cost and long-term operating cost of plant growth lamps. When choosing plant growth lamps, you should not only consider the initial investment cost, but also comprehensively consider the long-term operating cost and cost structure optimization methods. By rationally selecting lamps, designing lighting systems, using intelligent control systems, optimizing the planting environment, and taking advantage of preferential policies and energy-saving technologies, the cost of plant growth lamps can be effectively reduced, economic benefits can be improved, and sustainable development can be achieved.
