Embodiment
As shown in Figure 1, it is a circuit diagram of the present invention.The magnitude of voltage of circuit for testing voltage 2 sampling solar cells 1, be entered into then in the mobile phone CPU 5, the voltage of 5 pairs of detected magnitudes of voltage of mobile phone CPU and setting compares, if the former is higher than the latter, send signal by mobile phone CPU 5 so, electronic switch 3 is opened, this moment solar cell 1 can to mobile phone power supply or and to battery of mobile phone 4 chargings, wherein mobile phone CPU 5 comprises mobile phone CPU and mobile phone circuit.
Because operating handset voltage is generally 3.3-4.0V, therefore the about 3mA of standby current can selection work voltage be 4.0V, and size is at 600mm
2About the solar cell 1 of model.And the layout of solar cell 1 can be embedded in mobile phone to be easy on the position of daylighting, around the exterior display screen that is embedded in clamshell phone, as shown in Figure 2, solar cell 1 inlay exterior display screen 7 on the protecgulum 6 of clamshell phone around.
As shown in Figure 3, it is a control flow schematic diagram of the present invention.The magnitude of voltage of circuit for testing voltage 2 sampling solar cells 1 at first, the voltage to detected test voltage and setting compares in the mobile phone CPU 5 then, described setting voltage can be the voltage of battery of mobile phone 4, when test voltage is higher than setting voltage, send signal by mobile phone CPU 5, electronic switch 3 is opened, this moment, solar cell 1 provided most of operating current to mobile phone circuit, if illumination is too strong, when the open circuit voltage of solar cell 1 is higher than battery of mobile phone 4 voltages at this moment, solar cell 1 can carry out low current charge to it simultaneously with unnecessary current direction battery of mobile phone 4; When if test voltage is lower than setting voltage, then send signal by mobile phone CPU 5, electronic switch 3 cuts out, this moment, solar cell 1 was no longer to the mobile phone power supply or to battery of mobile phone 4 chargings.
The comparison of the open circuit voltage of above-mentioned solar cell 1 and the voltage of battery of mobile phone 4, can pass through circuit or program control, such as comparing the open circuit voltage of solar cell 1 and the voltage of battery of mobile phone 4, perhaps compare realization by the real-time voltage of CPU sampling battery of mobile phone 4 and the sampled voltage of solar cell 1 by two diodes.
Another big characteristics of the present invention are under the situation of illumination deficiency, utilize solar cell 1 to carry out ambient light intensity and detect, thereby realization is to the health care of human eye.
Solar cell 1 is because the different phenomenons of photon collision generation after N type and P type semiconductor cause the voltage difference generation.Therefore, the battery two ends will produce voltage difference under the situation of light having.Under the not enough unsaturated situation of illumination, especially under the situation that electronic switch 3 cuts out, this moment, voltage became certain direct ratio functional relation with intensity of illumination.Utilize this proportionate relationship, utilize above-mentioned detected test voltage again, can calculate current intensity of illumination.
Because also amateur photometer device is low to voltage-illuminance function required precision, can adopt look-up table conversion, as subordinate list 1, concrete numerical value can be recorded by test.According under the situation, solar cell 1 still can be kept certain voltage value, so photometric range of the present invention is wider at indoor weak light.
Subordinate list 1
| Open circuit voltage (V) | 5.00 | 4.90 | 4.80 | …… |
| Illuminance (Lux) | 150000 | 135000 | …… | …… |
Mobile phone CPU 5 is according to obtaining prevailing circumstances illuminance numerical value after voltage-illuminance transfer function conversion, then with described numerical value or be converted into literal and be input on the display screen of mobile phone, and the illuminance numerical value of above-mentioned numerical value and setting can be compared, if be lower than set point then mobile phone sends alarm signal, alarm signal can be sound or vibrations or flash of light, sound can be realized by the loud speaker of mobile phone itself, vibrations can realize that flash of light then can realize by the color lamp of mobile phone itself by the electromagnetic shaker of mobile phone itself.
As shown in Figure 4, it is electronic switch a kind of among the present invention, it is the MOS switching circuit, input IN connects solar cell 1, output OUT links to each other with battery of mobile phone 4 circuit with mobile phone circuit, and signal end S_EN links to each other with mobile phone CPU, when signal end S_EN input high level, conducting between input IN and the output OUT, on the contrary end between the two.This MOS switching circuit has unidirectional conduction, and electric current can only flow to output OUT from input IN, so can prevent that battery of mobile phone or outer handset alternating current circuit are to the reverse charging of described solar cell.
