Solar lawn lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of solar lawn lamp.

Background technology

At present, solar lawn lamp is applicable to mainly that as a kind of emerging green energy resource dwelling house community green grassland beautifies illumination and intersperses; The lawn, park is beautified and is interspersed; Its light source control cost is low, can also control photochromicly easily, changes the classification of light; Produce dynamic illusion, applied rapidly with its incomparable advantage.

Existing solar lawn lamp mainly is made up of lamp box, protective cover, circuit board, solar battery sheet and transparent Lamp cup; The base plate of the lamp box indent that makes progress forms alcove; During installation, elder generation turns over the lamp box, circuit board is flattened in the alcove and with glue be fixed; Then lamp box upset is lain in solar battery sheet on the lamp box top again, and solar battery sheet should be electrically connected with electrode pair on the circuit board, will protect cover cap and on solar battery sheet and with the lamp box, be interlocked; Again the lamp box and the protective cover that assemble are installed on the Lamp cup at last, and make the corresponding electrical connection of mounted LEDs lamp in circuit board and the lamp box; Like this, utilize solar battery sheet and circuit board to make the LED lamp luminous, the light that the LED lamp emits sees through the lighting function that transparent Lamp cup can be realized solar lawn lamp.

But this solar lawn lamp when assembling, needs the lamp box is overturn back and forth, and circuit board and solar battery sheet are installed in lamp box inside and outside respectively, and its electrical connection that installs and fixes mode and counter electrode is all more loaded down with trivial details.

The utility model content

In view of this, the purpose of the utility model is the solar lawn lamp that provides a kind of circuit board and solar battery sheet to be easier to assemble.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of solar lawn lamp comprises the protective cover, lamp box and the Lamp cup that fasten successively up and down, wherein; The bottom surface of said protective cover is provided with alignment pin; Said lamp box has recessed alcove, is provided with corresponding solar battery sheet and the circuit board that is electrically connected in this alcove, outside this alcove, is equipped with groove; The bottom surface of this groove is provided with the osculum of perforation to this lamp box, and said lamp box is positioned at the outer end face of this alcove and is provided with the locating hole suitable with this alignment pin.

The bottom surface of said alcove is provided with installing hole.

Convex with slot respectively on relative two interior sidewall surface of said alcove, said board side vertical cutting is located in this slot, and said solar battery sheet keeps flat and is erected on this slot.

Said circuit board comprises substrate and is laid in the integrated circuit on this substrate, a side surface of this substrate be provided with contact conductor and with the perpendicular cathode lead of this substrate, this contact conductor and corresponding with this integrated circuit respectively electrical connection of this cathode lead.

The side that said cathode lead parallels near said substrate and said cathode lead.

After adopting said structure, the utility model solar lamp for lawn has following beneficial effect:

One, compares with the structure inside and outside existing circuit board and solar battery sheet are divided in the lamp box; Because the utility model is installed in solar battery sheet and circuit board in the recessed alcove of lamp box together; Its counter electrode is easier to connect; Assemble and be easier to operation, improved packaging efficiency effectively; When using in the open, rainwater is pooled in the groove along the slit at protective cover and lamp box place, and then the osculum on the groove floor discharges, so the utility model also has good waterproof effect;

Two, lie in the lamp box of solar lawn lamp and with circuit board in the past and compare with the loaded down with trivial details mounting structure that glue is fixed; Because the circuit board in the utility model makes substrate and cathode lead vertical setting each other; Like this; In the slot of substrate-side vertical cutting in the lamp box, need not to carry out gluing grade and can realize the fixing of circuit board during installation; In addition, because circuit board is edge-on being inserted in the lamp box, saving takes up room, and is more convenient on the one hand in the lamp box, laying more components and parts, improves the space that utilizes of lamp box; On the other hand,, also help structural design, for example, can solar lawn lamp be made into the exquisite small and exquisite moulding that has more sight solar lawn lamp because the mounting means of circuit board is compacter.

The specific embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

Shown in Fig. 1-5, the utility model solar lawn lamp comprises protective cover 1, lamp box 2, Lamp cup 3, circuit board 4 and solar battery sheet 5.

Protective cover 1 is discoid, and its outer edge forms flanging downwards, in order to lamp box 2 on annular recess 24 suitable; The bottom surface of protective cover 1 is provided with two alignment pins 11.

Lamp box 2 has recessed alcove 21, and the bottom surface of alcove 21 is provided with installing hole 23, the installing LED lamp at installing hole 23 places, this LED lamp and circuit board 4 corresponding electrical connections; Outside alcove 21, be equipped with groove 24, the bottom surface of groove 24 is provided with the osculum 25 that connects to lamp box 2, and lamp box 2 is positioned at the outer end faces of alcove 21 and is provided with the locating hole 26 suitable with alignment pin 11.On relative two interior sidewall surface of alcove 21, convex with slot 22 respectively, circuit board 4 edge-on being inserted in the slot 22, solar battery sheet 5 keeps flat and is erected on the slot 22 that is convexly equipped with.In the alcove 21 group slot 22 can also be set, as required in order to plug another piece circuit board 4.
