The specific embodiment

See Fig. 1 garden lamp of the present utility model, the primary module 2 that forms by transparent upper cover 1, by the encapsulation of solar cell and control circuit, chassis 3, shell 4, light conducting cylinder 5, Transparent lamp shade 6, support bar 7 etc. are formed, wherein solar cell and automatic control circuit module 2 are cores of solar energy garden lamp, and it is that mode by the groove bayonet socket is connected with garden lamp chassis 3.Transparent upper cover 1 is used for preventing that rainwater from entering in the garden lamp.

See Fig. 2, the Copper Foil 26 on solar cell 22 and the battery plus-negative plate.Among Fig. 3, resin 21 is encapsulated in solar cell 22 and control circuit 24 on the single face copper clad plate 23, constitute primary module, one end of the copper clad plate 23 in this module has two through holes 27, the Copper Foil 26 of drawing from Fig. 4 solar cell 22 both positive and negative polarities passes through the voltage input end 28 that two through hole 27 directly are welded on automatic control circuit 24, primary module 2 outwards has on two elongated ends 29 deposited copper is all arranged, as the accumulator anode and cathode link.At solar cell 22 upper surface apposition one deck resins 21, light emitting diode 25 is installed in single face copper clad plate control circuit 24 middle parts.The circular hole that light emitting diode 25 will pass shell 4 bottom centre is deep in the light conducting cylinder 5.The battery link is positioned at primary module two elongated ends 29, and the conductive metal sheet contact in the deposited copper on the elongated end 29 and the chassis groove has realized being connected of battery and control circuit when going up.

As Fig. 5,6,7, be respectively chassis 3 vertical views, side view, upward view.Chassis 3 is supporting bodies that garden lamp holds battery, primary module 2, its architectural feature is that upper surface has and forms the corresponding groove 31 of primary module bayonet sockets with solar cell 22 and control circuit 24 and match, in the groove 31 on chassis 3 conductive metal sheet 32 is arranged, an end of conductive metal sheet 32 extends to chassis 3 reverse side and welds together with battery 33 both positive and negative polarities respectively.When primary module 2 is loaded onto chassis 3, and after rotating to an angle, the copper-foil conducting electricity on the elongated end 29 of primary module 2 closely contacts with chassis 3 upper grooves 31.Solar cell, automatic control circuit, battery just connect to get up integrated circuit of formation at this moment.

See Fig. 8, automatic control circuit with solar battery sheet as energy source and photo-sensitive cell.Wherein the pin 3 of element solar cell S1, resistance R 1, resistance R 2, triode Q1 and U1 has constituted simple control section.Their annexation is: the positive pole of solar cell S1 links to each other with the base stage of triode Q1 by resistance R 2 backs, and Q1 is 9014.Battery BATT is anodal to link to each other with the colelctor electrode of triode Q1 by resistance R 1 back.The pin 3 of U1 also is connected with the colelctor electrode of Q1, the grounded emitter of Q1.When daytime, solar cell S1 output voltage electric current makes triode Q1 conducting work, thus the current collection that makes Q1 low level very, so also input low level of the pin 3 of U1; During evening, solar cell S1 does not have electric current and voltage output, and triode Q1 ends, and the Q1 current collection is high level very, makes pin 3 input high levels of U1.The chip model of boosting ZXSC310.Solar cell S1 positive pole links together with the positive pole of battery BATT after through a Schottky diode Z1; The positive pole of battery is connected with the voltage input end pin 1 of U1 ZXSC310 again.Pin 1 connects H inductance L 1 back and links to each other with the colelctor electrode of triode Q2, and the pin 2 of U1 is an earth terminal.Pin 3 is a control end, and when pin 3 was input as high level, pin 5 voltage drive ends output high level made Q2 conducting work to the base stage of Q2, and light emitting diode is bright; Otherwise when pin 3 was input as low level, pin 5 also output low level ended Q2, and light emitting diode goes out.

Pin 4 is connected the other end ground connection of R3 for detecting current input terminal with resistance R 3 with the emitter stage of Q2.Light emitting diode is anodal to be connected minus earth with the colelctor electrode of Q2.
