Description
Technical field
The present invention relates to a kind of seven color LED fresh lights, it is fresh-keeping for refrigerator inside vegetables.
Background technology
Refrigerator is the indispensable electrical equipment of the modern life, vegetables or fruit etc. is put into refrigerator and can extend its shelf-life.But because vegetables and fruit can not proceed photosynthesis, it is rotten, rotten that the consumption that respiration constantly produces can make vegetables or fruit accelerate; And in refrigerator, plant is entered to implement illumination, vegetables can be made to continue photosynthesis, to offset the consumption that respiration produces, effectively delay the speed of vegetable spoilage, reach fresh-keeping effect.Although there is the fresh light in refrigerator in prior art, its fresh-keeping effect is not ideal.
Summary of the invention
The invention provides a kind of seven color LED fresh lights, object is the illumination ensureing vegetables in refrigerator, and this seven color LED both can meet the illumination needs of variety classes vegetables, can imitate again the lighting effect of outdoors sunlight, effectively can delay the rotten speed of vegetables, reach desirable fresh-keeping effect.
Seven color LED fresh lights of the present invention comprise circuit substrate, circuit substrate is provided with red LED lamp pearl, orange LED lamp bead, yellow LED lamp pearl, green LED lamp pearl, blue led lamp pearl, cyan LED lamp bead, purple LED lamp bead, described circuit substrate is connected with a power supply and a single-chip microcomputer, this single-chip microcomputer controllable power is supplied to the power of each LED lamp bead, thus needs according to difference the brightness regulating each LED lamp bead.
Further, the emission wavelength of described red LED lamp pearl is 650nm, the emission wavelength of described orange LED lamp bead is 605nm, the emission wavelength of described yellow LED lamp pearl is 585nm, the emission wavelength of described green LED lamp pearl is 520nm, the emission wavelength of described blue led lamp pearl is 440nm, the emission wavelength of described cyan LED lamp bead is 478nm, the emission wavelength of described purple LED lamp bead is 410nm, by the composite light source arranged above, the fruits and vegetables in refrigerator can be made to carry out normal photosynthesis, thus delay the rotten speed of fruits and vegetables, the fresh-keeping effect of fruits and vegetables is made to reach best.
Further, can arrange ultraviolet source on described circuit substrate, to play extra bactericidal effect, described ultraviolet source can adopt ultraviolet LED, also can adopt ultraviolet light pipe.
As preferred scheme, can be placed in a lamp box by the circuit substrate comprising each LED, lamp box exiting surface is provided with optical diaphragm group, and this optical diaphragm group can ensure the light uniform of assorted LED.
Accompanying drawing explanation
Fig. 1 is circuit substrate of the present invention;
Fig. 2 is a kind of lamp box structure.
Detailed description of the invention
As shown in Figure 1, seven color LED fresh lights of the present invention comprise circuit substrate, circuit substrate is provided with red LED lamp pearl, orange LED lamp bead, yellow LED lamp pearl, green LED lamp pearl, blue led lamp pearl, cyan LED lamp bead, purple LED lamp bead, described circuit substrate is connected with a power supply and a single-chip microcomputer, this single-chip microcomputer controllable power is supplied to the power of each LED lamp bead, thus needs according to difference the brightness regulating each LED lamp bead.In addition, as required the ultraviolet source (not shown) being used for sterilization can be set at circuit substrate.
In addition, the emission wavelength of red LED lamp pearl is 650nm, the emission wavelength of described orange LED lamp bead is 605nm, the emission wavelength of described yellow LED lamp pearl is 585nm, the emission wavelength of described green LED lamp pearl is 520nm, the emission wavelength of described blue led lamp pearl is 440nm, and the emission wavelength of described cyan LED lamp bead is 478nm, and the emission wavelength of described purple LED lamp bead is 410nm
Be illustrated in figure 2 a lamp box structure, circuit substrate can be arranged in this lamp box, the exiting surface of lamp box arranges optical diaphragm group.
Use seven color LED fresh lights of the present invention, its fresh-keeping effect is as follows:
Wherein, moisture content uses following formulae discovery:
Moisture content=
