The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The specific embodiment
The present invention relates generally to two parts: the structure division of device and the circuit part of device, below described respectively.
One, the structure of contrive equipment
In apparatus of the present invention, transparent cover 1 can adopt colourless transparent resin glass to make, and also can adopt colourless transparent plastic to make.Transparent cover 1, one can prevent dust, anti-gray etc.; The 2nd, can allow sunlight see through cover cap, be radiated on the solar cell E1.On the two side bending parts at transparent cover 1 rear portion, a columniform projection is arranged respectively, shown in the dashed circle among Fig. 1, columniform projection snaps in the circular hole of pedestal 2, just can realize being rotationally connected between transparent cover 1 and the pedestal 2.Light emitting diode D2, promptly illuminating lamp adopts the LED light emitting diode.Positive plate 3 and negative plate 6 are realized rechargeable battery E2 to be connected with other circuit by line.Solar cell E1, just usually said solar monocrystalline silicon, its function and effect are that the solar energy that receives is converted to electric energy.
In the present invention, printed substrate 4 is meant single plank, does not comprise any components and parts.Can arrange, weld electronic element, circuit, line on the printed substrate 4.
Be smooth, smooth near the middle position of pedestal 2 bottoms, use viscose glue that solar cell E1 and pedestal 2 are achieved a fixed connection.
On a sidewall of pedestal 2, have the rectangle installing hole, because installing hole is dimensioned to close-fitting cause and K switch has the cause (as shown in Figure 1) of automatic expansion structure, after K switch is firmly advanced in the installing hole, K switch fixed-site not only, and be difficult to take out again.Because before switch is pushed into installing hole, the plastic sheet of switch two sides is open, is pushed in the process of installing hole at switch, plastic sheet is extruded and closes up, and after switch was pushed into installing hole, plastic sheet lost the compressing of sidewall, can automatically spring open again, be difficult on the sidewall take out thereby switch is stuck in.
Outlet structure place at pedestal 2 sidewalls firmly inserts negative plate 6, owing to calculate through accurate in advance, the tight size of outlet structure can guarantee: the negative plate 6 that firmly inserts, can be firm be in the outlet structure.Outlet structure and pedestal 2 main bodys connect together, and in injection moulding was produced, outlet structure and pedestal 2 main bodys were carried out injection moulding in the lump and finished.Same reason at another sidewall of pedestal 2, is inserted fixedly positive plate 3.
In the accompanying drawing of this specification, Fig. 1 and Fig. 2 be as illustrative nature, 3 the light emitting diode D2 that only draw, and in the actual product, light emitting diode D2 can be a plurality of, such as being 5, is 10 for another example; Can also be many rows, such as 6 of every rows, 12 of 2 rows.
K switch is connected, can be charged or light a lamp.The transparent cover 1 that can close charges, and also can open transparent cover 1 and charge.If do not consider factors such as rainproof, purely from the performance of opto-electronic conversion, opening the transparent cover charging effect can be better.
In the time of charging, shine sunlight on the solar cell E1, produce electric energy,, electric energy is delivered to rechargeable battery E2 carry out energy storage by circuit and line.In illumination time,, rechargeable battery E2 discharges electric energy, by line etc., lights light emitting diode D2.
In the front portion of pedestal 2, screw passes front panel 5, printed substrate 4, is screwed into pedestal 2, and front panel 5, printed substrate 4, pedestal 2 threes fixedly are spirally connected successively.
Light emitting diode D2 is welded on the printed circuit board (PCB) 4.The round end position of light emitting diode D2 places in the middle of the circular hole of front panel 5.
Two, the circuit of contrive equipment
The electric principle of apparatus of the present invention, as shown in Figure 3.
In Fig. 3, can learn no matter charge or light a lamp, all need K switch is connected.
In the time of charging, shine sunlight on the solar cell E1, produce electric energy, charge to rechargeable battery E2 by current-limiting resistance R1 and diode D1.Meanwhile, the electric energy that solar cell produced, by current-limiting resistance R1 and divider resistance R2, base stage to triode VT1 is carried saturation current, triode VT1 saturation conduction, colelctor electrode flows to the base stage of next stage triode VT2 with low-voltage, causes triode VT2 to be in and to extinguish state by, light emitting diode.
When apparatus of the present invention were in the state of no bright light exposure, last no-voltage of solar cell E1 or voltage were very low; Though rechargeable battery E2 has gone up sufficient electric energy, but because the effect of the unidirectional conducting of diode D1, basic no current passes through on the base stage of triode VT1, so triode VT1 ends, in the base stage of its colelctor electrode output high level signal, make triode VT2 conducting and light light emitting diode D2 to triode VT2.
Apparatus of the present invention can be used as lighting device uses such as street lamp, turn off the light automatically daytime, charge; Stop charging night, light automatically.When using as lighting devices such as street lamps, this device can be placed on eminence, and K switch is in on-state all the time, does not need to change.
In addition, apparatus of the present invention can also be used as flashlight.Behind the daytime sufficient electrical energy, cut off K switch, and be carried at body.Can take out when needing in the dark evening, and after the connection K switch, light emitting diode D2 is just lighted.
Fig. 3 is as illustrative nature, 1 the light emitting diode D2 that only draws, and in the actual product, light emitting diode D2 can be a plurality of, as 5,10,15,20 or the like.
