Embodiment 1
As shown in Figs 1-4, a kind of laser plant lamp automatically adjusting laser intensity, is used for plant growth lighting, Neng Gousui
Extraneous intensity of illumination automatically adjusts laser intensity, comprising: for install laser plant lamp (laser plant lamp group 10) bracket L,
Control unit, photosensitive device, lighting module 1, power module 2, power supply fixed plate 3, radiator 4, shell 5, heat dissipation air port 6,
Optical sensor 7, heat release hole 8, conducting wire 9, laser plant lamp group 10, three-legged structure 11, stabilizer blade 12, lock 13, revolving-turret 14,
Screw knob 15 and radiator 16, bracket L are used to support laser plant lamp entirety, and power module 2 is constant current voltage, passes through silica gel
Mode for dispensing glue is mounted in power supply fixed plate 3, and lighting module 1 includes circuit board and laser plant lamp group 10, laser plant lamp
On circuit boards, laser plant lamp group 10 is connect 10 encapsulation of group with power module 2, and radiator 4 is connect with lighting module 1, by
Larger in the power of lighting module 1, so the heat generated is also big, radiator 4 can be discharged in time produced by lighting module 1
Heat, reduce temperature, improve the safety and reliability used, radiator 4 includes radiator 16.The illumination of photosensitive device
Sensor 7 is detachable to be fixed on 5 side of shell, to detect extraneous intensity of illumination and intensity of illumination is converted to voltage value letter
Number, control unit is electrically connected with photosensitive device by conducting wire 9.Because spectral region in 400nm-520nm (blue) and
Photosynthesis is influenced when 610nm-720nm (red) it is maximum, therefore the threshold values that control unit is set be 460nm (blue) and
Two shelves of 660nm (red), then select different threshold values shelves further according to the different stages of growth of plant.When in photosensitive device
When optical sensor 7 detects different intensities of illumination, optical sensor 7 converts voltage value signal simultaneously for intensity of illumination signal
Control unit is transmitted to be handled, control unit receive simultaneously each parameter is checked and is handled, by with set threshold values pair
Than, then respective handling is made to the signal, and re-start data setting, lighting module 1 will be received and be set again by control unit
Surely the data crossed and amendment obtain required laser intensity, act in laser plant lamp group 10, to complete one completely
Feedback regulation.
The laser plant lamp group 10 of the present embodiment uses 4 red laser lamps and 1 blue laser lamp combination irradiation first,
Plant performance is that plant height is short and small after a period of time, leaf development shortcoming.Optical sensor 7 can detect that plant institute is received at this time
Intensity of illumination, through detection spectral region in 320nm-410nm or so, the data are converted voltage value signal by optical sensor 7
And control unit is reached, this signal is made comparisons and is known lower than optimal with threshold values 460nm (blue) and 660nm (red) by control unit
Value, so resetting data in 460nm or 660nm or so, i.e., by changing laser lamp according to the different phase of plant growth
Portfolio ratio change laser intensity.
Embodiment 2
By in embodiment 14 red laser lamps and 1 blue laser lamp combination irradiation be replaced into 6 red laser lamps
With 1 blue laser lamp combination irradiation, connection type and measurement environment are remained unchanged.It, should due to increasing the number of laser lamp
The power of laser plant lamp can become larger, and the heat of generation also will increase, thus in order to reduce temperature, guarantee the reliability that uses with
Sensitivity opens up heat release hole 8, the heat dissipation effect of improving laser plant lamp in each side of shell 5.In the irradiation of the combination
Under, plant growth is slow, and leaf color is obviously dim, measures spectral region at this time between 500nm-620nm, finds the data
Neither between 400nm-520nm (blue), also not between 610nm-720nm (red), optical sensor 7 turns the signal
Control unit is sent to after turning to voltage value signal, and control unit is also (red by the signal and threshold values 460nm (blue) and 660nm
Color) it compares, the received intensity of illumination of plant differs larger with set threshold values as the result is shown, and illustrate this red blue lamp matches analogy
Formula is smaller on the influence of the photosynthesis of plant, therefore control unit can equally be reset newly according to the different phase of plant growth
Data transmission to lighting module 1, change laser intensity.When plant is in seedling or development stage, blue light is conducive to it
Lateral bud and leaf growth, so threshold values at this moment should select 460nm (blue), control unit is further according to the threshold values to the data obtained
It is handled；Red light is conducive to yielding positive results for plant, so the threshold values in flowering of plant result stage control unit should select
It is selected as 660nm (red), is reseted further according to threshold values comparison, obtains optimal intensity of illumination.
Remaining same embodiment 1.
Embodiment 3
Again the mixing ratio for changing red blue laser lamp is 8: 1, and radiator 4 is improved, as shown in Fig. 2, radiating
In addition to being equipped with radiator 16 in device 4, it is also additionally arranged radiator fan, radiator fan is mounted on the end face of shell 5, and wind direction blows to
Radiator 16 and overall fixed plate, can not only take away the heat of radiator 16, can also carry out to the element in overall fixed plate
Cooling guarantees the normal use of laser plant lamp, improves its service life.In the case where red-blue ratio example is 8: 1 irradiation, plant growing way is preferable
Limb and root system are all more strong, yield positive results faster, are mainly shown as red light at this time, i.e., spectral region is in 610nm-
720nm, such case meet the growth and development requirement of plant, especially more significant to the stage effectiveness of yielding positive results of plant,
It is general not have to reset numerical value again to change the laser intensity of laser plant lamp, but still needed to centainly in the plantlet stage of plant
Blue light illumination, then threshold values at this time should select 400nm-520nm (blue).To sum up compare, the red blue lamp of plant lamp group 10 is matched
It is also different on the photosynthetic influence of plant than number difference.The ratio that the chromatography ratio of usual red blue lamp is 6-9: 1, and 8
: 1 or 9: 1 proportion of red blue light is best to plant growth, thus in the present embodiment 3 laser lamp red, blue lamp number
Proportion selection 8: 1.
Embodiment 4
After the proportion of red blue light (8: 1) of laser plant lamp group 10 has been determined, the stabilization for considering laser plant lamp is also needed
Property and direction of illumination, bracket L stainless steel or aluminum alloy materials production whole using bracket L support laser plant lamp.Such as Fig. 3
Shown, the bottom bracket L can be set to three-legged structure 11, increase its stability, 12 middle part of each stabilizer blade of three-legged structure 11 is again
It is provided with lock 13, can control the flexible and angle of each stabilizer blade 12, convenient rationally to irradiate to the plant of different plant heights, bracket
