Description
Technical field
The utility model relates to a kind of new plant growth lamp, especially a kind of industrialized agriculture LED plant growth lamp that can the simulating nature luminous environment.
Background technology
The plant indispensable energy source of growing only, some high-tech agricultural places now, plant growth lamp has begun a large amount of uses.But present plant growth lamp has also satisfied not the needs of plant growth under many circumstances.Main cause is that present plant growth lamp on the market mostly has only a kind of fixedly ignition mode and a kind of fixing light of emission; Can not simulating nature light; Can not change light in the physiological characteristic of different growing stage according to different plants, satisfy not the demand of plant growth.
The utility model content
The utility model technical problem to be solved provides a kind of particular structural and controlling schemes, to satisfy different plants in the demand of different growth phases to light, reaches the industrialized agriculture LED plant growth lamp of the control purpose of simulating nature light.Be mainly used in places such as traditional agriculture, industrialized agriculture environment.
The utility model technical problem to be solved realizes through following technical scheme:
A kind of industrialized agriculture LED plant growth lamp comprises control module, MCU and LED lamp group, and said control module establishes a communications link through data protocol bus and MCU, and said MCU connects said LED lamp group through constant-flow driver.
Further, said LED lamp group comprises three groups of LED lamps, and one group is the red-light LED lamp, and one group is blue LED lamp, and one group is white LED lamp.
Further, the ratio of said red-light LED lamp, blue LED lamp and white LED lamp is 7: 1: 1.
Further, the wave-length coverage of said red-light LED lamp is 620-630nm and 640-780nm, and the wave-length coverage of said blue LED lamp is 420-460nm and 460-470nm, and the colour temperature of said white LED lamp is 28000K.
Advantage of the utility model and beneficial effect are:
The novel industrialized agriculture LED plant growth lamp of the utility model is made up of ruddiness and blue light, can cover the required wave-length coverage of photosynthesis.Effective simulating nature light, and can satisfy each kind of plant in the demand of different growth periods at the proportion of red blue light of the rational coordinate plant growth lamp of the different growth phases of different plants to light.Insecticidal function being arranged again, have higher science, is Development Trend.
This LED plant growth lamp type of wavelength is enriched, is become with plant photosynthesis and the spectral region of photomorphogenesis is coincide; Frequency spectrum wave width half-breadth is narrow, can make up as required to obtain pure monochromatic light and complex spectrum; The light that can concentrate specific wavelength is irradiate crops balancedly.

Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, how the industrialized agriculture LED plant growth lamp that further specifies the utility model is realized.
As shown in Figure 1, the utility model comprises control module, MCU and LED lamp group, and said control module establishes a communications link through data protocol bus and MCU, and said MCU connects said LED lamp group through constant-flow driver.
Said control module comprises industrial computer and communication module, is used for through predetermined instruction control MCU.
Said LED lamp group comprises three groups of LED lamps, and one group is the red-light LED lamp, and one group is blue LED lamp, and one group is white LED lamp.The ratio of said red-light LED lamp, blue LED lamp and white LED lamp is 7: 1: 1.
Red-light LED lamp and blue LED lamp are used for simulating nature light, and white LED lamp is used for kill pests.
The wave-length coverage of said red-light LED lamp is 620-630nm and 640-780nm; The wave-length coverage of said blue LED lamp is 420-460nm and 460-470nm; Adopt above-mentioned wavelength combination; Add that red, blue monochromatic light according to the illumination mode that cooperates, has significantly reduced plant seed germination time and growth time, the colour temperature of said white LED lamp is 28000K.
Industrial computer transmits control signal to MCU through communication module, and MCU accomplishes different ignition mode according to the control signal control constant-flow driver driving LED lamp group of industrial computer, can adopt to mix and light, or monochromatic light is lighted.
Like Fig. 2, shown in Figure 3; Described MCU produces 3 road PWM output control constant-flow driver DD311 by mega8 seat main control chip according to the control signal of industrial computer to light and control LED lamp group, reaches the purpose that changes ruddiness and blue light ratio through the PWM pulse-width modulation.
As shown in Figure 3, described constant-flow driver is to be made up of DD311 (U2, U3, U4).DD311 is a single channel great power LED constant-flow driver; DD311 is the LED constant-flow driver of single channel output; In build current mirror and current switch assembly, be to aim at the chip that drives great power LED and design, DD311 can drive the input current up to 1 ampere; And can see through adjustment sets arbitrarily output current with reference to input current (IREF) size; Output current value is about 100 times IREF, and IREF can be set by adjustment plug-in resistance or bias voltage (bias) voltage, finely tunes or enables brightness between bias voltage recoverable LED and differ or realize that overall brightness is adjusted simultaneously between plurality of LEDs; The output of chip can bear the voltage up to 36V, supports the serial connection of many great power LEDs to use.In build output enable end (Enable), can realize easily that the high gray of great power LED is used characteristic.
As shown in Figure 4, described communication module is the serial communication modular that is made up of MAX485 (U5), and the completion industrial computer is communicated by letter with MCU's, and serial port communication technology is ripe and convenient, selects serial communication, and is convenient and reliable.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
