Description

Solar lawn lamp
Technical field
The utility model relates to that a kind of power consumption is little, the outdoor illumination of long-life type; particularly a kind of utilize solar energy glass lamination battery component as energy sources, with parts such as Ni-MH battery, lithium battery or super capacitors as energy-storage travelling wave tube; and be that main control circuit is controlled automatically by IC chip U1 mainly, had the solar lawn lamp of putting defencive function.Be widely used in all kinds of open-air lawns.
Background technology
At present, utilize the market demand of solar lawn lamp of solar energy power generating principle development very big, but general solar lawn lamp generally adopts and drips glue baby battery assembly and produce bubble down in that the sun shines, less than 1 year battery component with regard to premature failure; Control circuit does not possess accumulator super-charge, crosses and to put defencive function, makes the life of storage battery too short, does not often reach itself projected life, just broke down in common about 1 years, and control circuit adopts discrete elements such as resistance, electric capacity, diode more, and efficient is low.Light-operated induced electricity sub-element adopts non-linear photosensitive resistance, actuation time error big, to be subject to the ambient dust influence malfunctioning, causes the misoperation on daytime, reliability reduces.These problems had both increased the replacing maintenance cost of existing solar lawn lamp, had caused the waste of resource again.So existing solar lawn lamp technology is demanded urgently improving.
The utility model content
The purpose of this utility model provides a kind of improved solar lawn lamp, fundamentally solve low, the problems such as maintenance cost big, the wasting of resources of life-span that existing solar lawn lamp exists, its reasonable in design, adopt highly integrated control circuit, has the advantage that power consumption is little, energy-conservation, safeguard simply, save cost, significantly improve the Lawn lamp dependability, increase the service life.
The technical solution of the utility model is: this solar lawn lamp comprises the lamp body that has holder and lower connecting plate, be assembled with the upper junction plate of solar cell, the diffuser of connecting struts and built-in light emitting diode and be encapsulated in control circuit board in the lamp body, its technical essential is: described solar cell adopts the glass laminates assembly as light-operated sensing device, described solar cell in the integrated control circuit that is printed on described control circuit board is with after battery utilizes the counnter attack charging diode in parallel, form control loop by switch and IC chip U1, described IC chip is in parallel with divider resistance, forms control loop with energy storage inductor of connecting and described light emitting diode simultaneously.
Advantage of the present utility model and positive technique effect are: because the glass laminates assembly life-span that solar cell adopted can reach 25 years, solar cell can be realized light control functionality by the photovoltaic effect of IC chip U1 output, so significantly improve the Lawn lamp dependability, increase the service life.Because of the solar cell in the integrated control circuit that is printed on control circuit board with after battery utilizes the counnter attack charging diode in parallel; form control loop by switch and IC chip; so charge a battery in the sun, can realize preventing to accumulator super-charge, cross and put protection.IC chip is in parallel with divider resistance to can be used for being provided with overdischarge pressure value, and the control loop with energy storage inductor L that connects and light emitting diode are formed is used to adjust the output current size.In sum; this apparatus structure is reasonable in design; it adopts highly integrated IC chip U1 is main control circuit; and it is light-operated with glass laminates assembly type solar cell for supplying power and realization; overcharge by having, cross the accumulators store electric energy of putting defencive function, reach the adjustable purpose of output current, thereby simplified the internal circuit configuration of solar lawn lamp; and, improved the reliability of integrated circuit to a great extent because the element that need articulate is less.Therefore, its power consumption is little, energy-conservation, maintenance is simple, and preparation easily, saves cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of circuit theory diagrams of the present utility model.
Sequence number explanation among the figure: 1 solar cell, 2 upper junction plates, 3 ornamental strips, 4 connecting struts, 5 lower connecting plates, 6 lamp bodies, 7 holders, 8 diffusers.
The specific embodiment
According to Fig. 1-2 concrete structure of the present utility model is described in detail.This solar lawn lamp comprises the diffuser 8 of the lamp body 6 that has holder 7 and lower connecting plate 5, the upper junction plate 2 that is assembled with solar cell 1, ornamental strip 3, connecting struts 4 and built-in LED (present embodiment is selected 6 for use) and is encapsulated in control circuit board (not shown) in the lamp body 6.The glass laminates assembly that solar cell 1 adopts as light-operated sensing device, this specification, shape as the glass laminates assembly of light-operated sensing device should be according to actual needs with may determine, fixedly be assembled on the upper junction plate 2, and adopt the degree of protection of IP65 to be connected with control circuit board in the lamp body 6.The diffuser 8 of built-in LED utilizes connecting struts 4 and ornamental strip 3 to be assembled between the upper and lower connecting plate 2,5 as illuminator.
As shown in Figure 2, the electronic component in the integrated control circuit that is printed on control circuit board mainly contains IC chip U1 (present embodiment is selected digital module QX5233DE for use), counnter attack charging diode D1, divider resistance R1, R2, energy storage inductor L1, LED, switch S 1, parts such as solar cell SO, battery BAT.Solar cell SO in the control circuit is with after battery BAT utilizes counnter attack charging diode D1 in parallel, form control loop by switch S 1 with IC chip U1, IC chip U1 is in parallel with divider resistance R1, R2, forms control loop with energy storage inductor L1 that connects and LED 1 simultaneously.Battery BAT links to each other with integrated chip U1, and power supply is provided.Solar cell SO links to each other with 1 pin of IC chip U1 and realizes light-operated effect, about light-operated starting resistor 0.2V.When daytime, solar cell SO voltage was greater than 0.2V, light-operated startup, circuit turn-on.When night, solar cell SO voltage was less than 0.2V, light-operated stopping, circuit disconnects.Energy storage inductor L1 in the control circuit can adjust the output current size, and L1 is more little for energy storage inductor, and the LED electric current is big more.Divider resistance R1, R2 in the control circuit are used to be provided with overdischarge pressure value.When solar cell SO voltage was lower than 550mV* (1+R1/R2), IC chip U1 carried out putting protection to battery BAT automatically, cut off circuit, and LED turn-offs; And when voltage is higher than 650mV* (1+R1/R2), the LED conducting.
