Description of drawings
Fig. 1 is that said plant growth lamp substrate of the utility model and basic onboard led lamp pearl are arranged the enforcement illustration;
Fig. 2 is that sketch map is used in said plant growth lamp combination;
Fig. 3 is said control circuit sketch map;
Fig. 4 is a voltage supply circuit sketch map in the said control circuit.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
The said LED plant growth lamp of the utility model; Comprise led light source and control circuit thereof; Its light source is that the LED lamp pearl of different colours is arranged by ad hoc fashion; Make on its substrate that evenly distributes, and regulate and control promotion and the adjusting of the realizations such as luminous intensity of versicolor lamp pearl the plant growth state and the speed of growth through control circuit.Because the ruddiness blue spectrum is photosynthesis of plant and the main action spectrum that grows; Therefore fixedly install the lamp pearl of red blue two kinds of colors on the substrate; In addition according to the needs of the different growth phases of different plants or same kind of plant, arrange in pairs or groups other one or more have a lamp pearl of the fixed wave length that is fit to this plant or this growth period effect.For example wavelength is 320-380nm (ultraviolet system), 630nm (pink colour system), 730nm (infrared system).
The inherent colour that owing to human eyes under the above-mentioned illumination visual effect of plant obviously is different from plant under the natural environment in addition; Consider from visual effect and hommization; Can on substrate, increase 540-560nm (green system), colour temperature less than the lamp pearl that 5000k (white color system) etc. can improve the human eyes visual effect, increase the sight under the specific environment.
Like Fig. 1 is the arrangement enforcement illustration of said plant growth lamp substrate and basic onboard led lamp pearl.The substrate structure that is rectangle among the embodiment, a substrate is provided with 50 lamp pearls.The particular arrangement mode of said lamp pearl is: red colored lamp pearl and blue lamp pearl are spaced; The blue lamp pearl is spaced with the fixed wave length lamp pearl with coordinate plant growth effect; The red colored lamp pearl is spaced with the lamp pearl with fixed wave length of coordinate plant growth effect, and the red colored lamp pearl can adjacently be arranged.The said LED lamp of the utility model can be regarded a plant growth lamp module as, when needs light filling intensity or space are big, can said plant growth lamp permutation and combination be used together, and adjusting function is constant.The rectangular substrate structure of rule is convenient to single LED plant growth lamp is made up along its length or width in the present embodiment, and is as shown in Figure 2.Certain said substrate in combination also can be other shape, as long as each substrate is convenient to mutual combination and is used, the value volume and range of product of lamp pearl also can increase and decrease as required on the substrate.The arrangement mode of the pearl of lamp described in the utility model is a preferred arrangement.
