Description
Technical field
The present invention relates to a kind of LED intelligence plant growth lamp; Relate to the light irradiation apparatus in a kind of LED intelligence plant growth cabinet specifically, utilize microcontroller ATmega8 single-chip microcomputer, in conjunction with corresponding circuit; Produce the natural light environment of simulation, thereby the plantation or the vegetables that are used for plant produce.
Background technology
Luminous environment is one of indispensable important environmental factor in the growth and development of plants, and light is regulated growth and development of plant through influencing photosynthesis, photomorphogenesis and photoperiod.Correlative study shows that already the blue light of visible light medium wavelength scope 400～510nm, the ruddiness of wave-length coverage 610～720nm have big efficient to photosynthesis.At present, the lamp that much is used for plant growth is arranged on the market, but these plant growth lamps efficient is very low under many circumstances, also satisfied not the needs of plant growth.Main cause is that present plant growth lamp on the market mostly has only a kind of fixedly ignition mode, just has only a kind of fixing wavelength after this lamp dispatches from the factory, and this does not obviously meet the plant growth rhythm.Given this, the LED intelligence plant growth lamp that needs a kind of simulating nature light adjustable wavelength of design.
Summary of the invention
Technical problem to be solved by this invention is, a kind of light irradiation apparatus that can be applied in the intelligent plant growth cabinet is provided, and can make full use of the efficient of light, and have wavelength-tunable, intensity variable, intelligent plant growth lamp that can the simulating nature luminous environment.
The technical scheme that the present invention adopted is: a kind of LED intelligence plant growth lamp has host computer; Main control module; Communication module; The LED driver module; LED lamp group.
Described host computer is an industrial computer, and main effect is to produce corresponding LED drive signal through predetermined instruction control main control module.
Described main control module adopts the ATmega8 single-chip microcomputer, produces three road pwm control signals according to the control signal of host computer, reaches the purpose that changes ruddiness and blue light ratio through the PWM pulse-width modulation.
Described communication module adopts the MAX485 chip to constitute serial communication circuit, is used for communicating by letter between host computer and the main control module.
Described LED driver module adopts single channel great power LED constant-flow driver DD311, is used for driving LED lamp group and produces corresponding illumination condition.

Embodiment
Below in conjunction with accompanying drawing and instance the present invention is described further.
As shown in Figure 1, LED intelligence plant growth lamp of the present invention has host computer (1); Main control module (2); Communication module (3); LED driver module (4); LED lamp group (5).
Host computer (1) transmits control signal to main control module (2) through communication module (3), and main control module (2) is accomplished different ignition mode according to control signal control LED driver module (4) the driving LED lamp group (5) of host computer (1).
Described host computer is an industrial computer, and main effect is to produce corresponding LED drive signal through predetermined instruction control main control module.
As shown in Figure 2, described main control module adopts low-power consumption microcontroller ATmega8 single-chip microcomputer (U1), and the control signal of sending according to host computer produces three road PWM pulse-width signals, is used for the driving LED driver module, thereby produces needed illumination condition.
As shown in Figure 3, described communication module constitutes serial communication circuit by MAX485 chip (U5), and the completion host computer is communicated by letter with main control module.Serial port communication technology is ripe and convenient, selects serial communication, and is convenient and reliable.
As shown in Figure 4, described LED driver module is made up of single channel great power LED constant-flow driver DD311 (U2, U3, U4).DD311 is the LED constant-flow driver of single channel output, in build current mirror and current switch assembly, be to aim at the driving great power LED and the chip that designs.
As shown in Figure 5, described LED lamp group is made up of 3 groups of LED lamps.The ratio of three groups of lamps is: 7: 1: 1, wherein, one group of red-light LED lamp, one group of blue LED lamp and one group of white LED lamp.Red-light LED lamp and blue LED lamp are used for simulating nature light through LED lamp group control circuit, and white LED lamp is the white light of colour temperature 28000K, mainly are used for killing larva.
