Description

Technical Field

[0001] The present invention relates to the technical field of plant cultivation equipment, and in particular to an intelligent and efficient plant growth lamp and a use method thereof. Background Art

[0002] With the development of science and technology, LED plant growth lights are increasingly widely used in various plant plantings, but they are still in the primary stage. The combination of red, blue, green, infrared, ultraviolet, and infrared light is not mature enough for thousands of different plants, especially crops, and the so-called "light formula" is not yet mature. Moreover, it cannot be flexibly changed for different plants and different growth periods. The existing lighting equipment corresponds to one lighting equipment for different growth periods. The entire light source must be replaced for the change, which increases the planting cost of growers. How to reduce energy consumption and production costs during plant growth so that the cost performance is better than that of traditional agricultural production crops is another technical bottleneck that needs to be solved urgently. Therefore, it is necessary for us to develop a new generation of intelligent and efficient plant growth lights that can meet the requirements of flexible lighting changes and reduce energy consumption. Summary of the invention

[0003] The present invention provides an intelligent and efficient plant growth lamp and a use method thereof, which can flexibly change lighting requirements and reduce energy consumption.

[0004] The present invention adopts the following technical solutions:

[0005] An intelligent and efficient plant growth lamp, characterized in that it includes: a bridge rectifier circuit, a four-channel PWM / PFM pulse-controlled constant current drive power chip, a microwave wireless communication module, a dimming and color-adjusting digital toggle switch group, and four groups of LED light sources with different light wavelengths; the output end of the bridge rectifier circuit is connected to the first input end of the four-channel PWM / PFM pulse-controlled constant current drive power chip, the output end of the microwave wireless communication module is connected to the second input end of the four-channel PWM / PFM pulse-controlled constant current drive power chip, the output end of the dimming and color-adjusting digital toggle switch group is connected to the third input end of the four-channel PWM / PFM pulse-controlled constant current drive power chip, and the output end of the four-channel PWM / PFM pulse-controlled constant current drive power chip is connected to the four groups of LED light sources with different light wavelengths;

[0006] The dimming and color adjustment digital toggle switch group adjusts and controls the four-channel PWM / PFM pulse control constant current driver power chip to output four groups of LED light sources with different wavelengths of infrared, red, blue and green light; the microwave wireless communication module adjusts and controls the four-channel PWM / PFM pulse control constant current driver power chip to output four groups of LED light sources with different wavelengths of various light colors.

[0007] In this solution, by using a dimming and color adjustment digital toggle switch group, each group corresponds to a different light ratio mode, so as to adjust and control the four-channel PWM / PFM pulse control constant current driver power supply chip to output four groups of infrared, red, blue and green light of LED light sources with different light wavelengths, thereby achieving flexible changes in lighting requirements for different growth stages of plants and reducing the planting costs of growers. It should be noted that the four-channel PWM / PFM pulse control constant current driver power supply chip uses PWM, PFM, PWM and PFM to work simultaneously, and works in one of the three working modes.

[0008] Preferably, the four groups of different light wavelengths of the LED light source are 380nm, 440nm, 660nm and 730nm respectively. This solution is to select the light source wavelengths required by plants at different growth stages to promote plant growth, and to prepare the light ratios required by plants at different growth stages.

[0009] As a further improvement of the scheme, the radiation energy value ratio of the light wavelengths of 380nm, 440nm, 660nm and 730nm is 1:1:5:1 or 1:1:7:1 or 1:1:9:1 or 1:1:11:2. This scheme can correspond to the primary stage, intermediate stage, pre-flowering stage and post-flowering stage of plant growth, ensuring that the most appropriate light allows the plant to grow efficiently, thereby avoiding unnecessary waste of light source irradiation.

[0010] As a further improvement of the solution, the LED light source is a high-radiation energy LED lamp bead with a single lamp bead ≥3.0 micromoles / second.

[0011] Preferably, the four-channel PWM / PFM pulse-controlled constant current drive power chip is an MPU chip of model SW-LPLCON0193.

[0012] The present invention also provides a method for using the intelligent and efficient plant growth lamp, using the LED light source as a single lamp bead with a high radiation energy of ≥3.0 micromoles / second, and reducing the power of the lamp bead by 25%. This solution can obtain higher efficiency and stable photosynthetic light flux (PPF). BRIEF DESCRIPTION OF THE DRAWINGS

[0017] When in use, the dimming and color-adjusting digital toggle switch group adjusts and controls the four-channel PWM / PFM pulse control constant current drive power supply chip to output four groups of infrared, red, blue and green light ratios of LED light sources with different light wavelengths of 380nm, 440nm, 660nm and 730nm. By toggling the four toggle switches 1 / 2 / 3 / 4, the combinations can be: 0000, 0001, 0011, 0111, 1111, 1000, 1100, 1010,...1111, etc. Each group can correspond to a different light ratio of infrared, red, blue and green light, thereby realizing flexible changes in the light requirements for plants in different growth stages and reducing the planting costs of growers. The radiation energy value ratio of 380nm, 440nm, 660nm, and 730nm light wavelengths is 1:1:5:1 or 1:1:7:1 or 1:1:9:1 or 1:1:11:2, corresponding to the primary stage, intermediate stage, pre-flowering stage, and post-flowering stage of plant growth, ensuring that the most appropriate light allows efficient growth of plants, thereby avoiding unnecessary waste of light source irradiation and further reducing energy consumption. The microwave wireless communication module adjusts and controls the four-channel PWM / PFM pulse control constant current drive power supply chip to output the brightness of four groups of LDE light sources with different light wavelengths and various light colors. In the microwave communication module, there are fixed scene modes with brightness and light ratio from 1 to several light colors. The microwave remote control is used to start different fixed scene modes to control the circuit to achieve the brightness requirements of different light colors.

The function of channel MOS1-MOS4 is to turn on or off under the control of SW-LPLCON0193IC chip 8. When SW-LPLCON0193IC chip 8 outputs a high level, the MOS tube is turned on and the LED on the corresponding channel lights up.

The combinations can be: 0000, 0001, 0011, 0111, 1111, 1000, 1100, 1010, ... 1111, etc. Each group can correspond to a different light ratio of infrared, red, blue and green light, thereby realizing flexible changes in the light requirements for plants at different growth stages and reducing the planting costs of growers. The radiation energy value ratio of light wavelengths of 380nm, 440nm, 660nm and 730nm is 1:1:5:1 or 1:1:7:1 or 1:1:9:1 or 1:1:11:2, corresponding to the primary stage, intermediate stage, pre-flowering stage and post-flowering stage of plant growth, ensuring the most appropriate light for efficient growth of plants, thereby avoiding unnecessary waste of light source irradiation and further reducing energy consumption.
