Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of LED plant growth lamp, comprise LED light source 1, power supply 2 and single-chip microcomputer 3, single-chip microcomputer 3 comprises time block 4 and PWM module 5, time block 4 connects timer 6, PWM module 5 connects power supply chip 7, PWM module 5 is for the timing signal output pwm signal according to time block 4, power supply chip 7 adjusts the output current of power supply 2 for the pwm signal exported according to PWM module 5, LED light source 1 connects power supply 2 and single-chip microcomputer 3 forms loop, be packaged with red in LED power 1, green, blue three kinds of LED chips, three kinds of LED chips are connected to three output pins of single-chip microcomputer 3, three kinds of LED chips are used for the LED luminescence controlling the respective color that it drives according to the output signal of single-chip microcomputer 4.
According to the input of timer 6, the time block 4 in single-chip microcomputer 3 is to PWM module 5 and the output pin transmission timing signal that connects with three kinds of LED chips, and three kinds of LED chips drive the LED of respective color luminous according to timing signal, realize the control of LED light source color; PWM module 5 is then according to timing signal output pwm signal, and power supply chip 7 changes the output current of power supply 2 according to pwm signal, namely changes the size of current flowing through LED light source 1, thus realizes the control of LED light source 1 brightness.Timer 6 embedded software control module, can set timing parameters according to plant growing cycle.
In order to ensure that the illumination that plant obtains is penetrated evenly, in an embodiment of the present utility model, LED light source 1 comprises red-light LED 8, green light LED 9 and blue-ray LED 10, and the LED cross arrangement of three kinds of colors.Light distribation when so not only can ensure monochromatic light exposure is even, and even light mixing when can ensure that the light of multiple color irradiates simultaneously.
In order to realize the Long-distance Control of LED light source 1, in an embodiment of the present utility model, wireless network module 11 is provided with in timer 6, wireless network module 11 communicates with mobile terminal 12, only have corresponding control software design in mobile terminal 12, the timing parameters that wireless network module 11 sends for mobile terminal receive 12 also writes timer 6.User, when obtaining on-the-spot plant growth state by approach such as monitoring remote videos, can write timing parameters as required, make control more flexible in timer 6.
In order to the light color realized when mixed light irradiates controls, in an embodiment of the present utility model, the input of three kinds of LED chips connects the different output pins that a power supply chip 7, three power supply chips 7 are connected to PWM module 5 respectively.Control the brightness of the LED of three kinds of colors like this by single-chip microcomputer 3 programming realization respectively, thus various photochromic proportioning can be controlled when mixed light.
Wherein, single-chip microcomputer 3 itself does not have pwm pin, and need by programming simulation pwm signal, in the square wave of certain frequency, adjustment high level and low level duty ratio, can realize output pwm signal.First, cycle T and the duty ratio D of PWM is determined, after determining these, a time reference t can be produced with timer, such as timer overflows the time that the time of n time is the high level of PWM, then D*T=n*t, similar PWM low level time of can obtaining needs how many time reference n '.During coding, only need define n and n ' of timer according to time reference t.Such as, define a flag bit flag, high flat or low level is exported according to the Determines of flag, high level is exported when supposing definition flag=1, with the number of times that a variable goes recording timer to interrupt, each interruption just allow record interruption times variable+1, inside interrupt routine, judge whether the value of this variable has arrived n, illustrate that the time of high level is much of that if arrived, so just changing flag is 0, output low level, record interrupts the value clearing of variable simultaneously, + 1 is remained unchanged when each interruption, jumping according to the situation of flag=0 goes the value judging record variable whether to arrive n ' if arrived, illustrate that the low level time of PWM is much of that, so just change flag=1, output changes high level, record degree variables to reset simultaneously, restart, circulation like this just can obtain the PWM waveform wanted.
In order to reduce the waste caused due to light scattering in irradiation process, in an embodiment of the present utility model, LED light source 1 is installed on reflector, and its front is coated with snoot.Reflector is by the light reflection of plant dorsad to towards plant, and snoot avoids the diffuse reflection of LED light source, increases LED light source range of exposures.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
