Description
Technical field
The present invention relates to the special-purpose growth lamp of a kind of controllable LED plant, relate to the light irradiation apparatus in a kind of LED-based intelligent plant growing cabinet specifically, utilize microcontroller ATmega128 single-chip microcomputer, in conjunction with corresponding circuit, simulate the optimum environment of plant growing, thereby be applied to plantation of plant or the production of vegetables.
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 by influencing photosynthesis, photomorphogenesis and photoperiod.Correlative study shows that already the blue light of visible light medium wavelength scope 450nm and the ruddiness of wave-length coverage 660nm have big efficient to photosynthesis of plant.At present, the different plant growth lamp of a lot of patterns is arranged on the market, but these plant growth lamps efficient is very low under many circumstances, and do not satisfy the needs of plant growing.Main cause is that present plant growth lamp on the market mostly is incandescent lamp or a kind of fixedly ignition mode is only arranged, and unadjustable, this does not obviously meet the plant growing rule.Given this, the needs design is a kind of can regulate the LED intelligence plant growth lamp of brightness and red blue lamp proportioning by simulating nature light.
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 growing cabinet is provided, can makes full use of the efficient of light, and have intensity variable, red blue lamp proportioning is variable, the special-purpose growth lamp of controllable LED plant that can the simulating nature luminous environment.
The technical solution adopted in the present invention is: the special-purpose growth lamp of a kind of controllable LED plant 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 by predetermined instruction control main control module to drive signal.
Described main control module adopts the ATmega128 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 by the PWM pulsewidth 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
The invention will be further described below in conjunction with accompanying drawing and example.
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) by communication module (3), and main control module (2) is finished 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 by predetermined instruction control main control module to drive signal.
As shown in Figure 2, described main control module adopts low-power consumption microcontroller ATmega128 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), finishes communicating by letter of host computer and 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 of single channel great power LED constant-flow driver DD311 (U2, U3, U4).DD311 is the LED constant-flow driver of single channel output, and built-in current mirror and current switch assembly are to aim at the chip that drives great power LED and design.
As shown in Figure 5, described LED lamp group is made of 3 groups of LED lamps.Wherein, one group of red-light LED lamp, one group of blue LED lamp and one group of white LED lamp, totally 168, red light is 7: 1 with the quantity ratio of blue lamp.Red-light LED lamp and blue LED lamp are used for simulating nature light by LED lamp group control circuit, and white LED lamp is the white light of colour temperature 28000K, is mainly used to kill larva.
