Fixed solar lawn lamp
The utility model belongs to civilian light fixture category.
A kind of the irradiation of sunlight energy directly is converted to electric quantity of power supply, it is luminous to utilize this power supply to light bulb, thereby beautifies, illuminates the park, the fixed solar lawn lamp that greenery patches and flower garden etc. is located.
Along with the development of society, environmental greening, beautify and in urban construction, be in more and more important position, known be used to illuminate beautify the Lawn lamp that greenery patches, flower garden etc. are located, be to emit light with the bright bright lamp bubble of common mains lighting supply to beautify the flower garden.The shortcoming of this flower garden Lawn lamp is when planning construction, must excavate trench, wiring.The preliminary engineering amount is bigger, the cost of whole Lawn lamp in the mounting arrangements process is big, and need consume the electrical network electric weight during normal operation after installing, operating cost is also high, the purpose of this utility model is: invent and a kind of the irradiation of sunlight energy directly is converted to electric quantity of power supply, it is luminous to utilize this power supply to light bulb, beautifies to illuminate the fixed solar lawn lamp that park, greenery patches and flower garden etc. are located.The advantage of this solar lawn lamp is that it in whole planning installation process, does not need to excavate trench, does not need to bury underground pipeline, does not need to consume grid power during work.Can be installed in any place of need installing arbitrarily, very simple and convenient, install the back when using without any operating cost, do not need special messenger's maintenance management, be a kind of safe, energy-conservation, range of application green product very widely.
The technical solution of the utility model is such: fixedly in the lamp bracket storage battery is being installed, the output of storage battery is connected with special LED cluster bulb by switch, storage battery is connected with solar panel with back panel wiring by controller simultaneously, solar panel is installed in the top of going up most of Lawn lamp, be on the reflective top cover of Lawn lamp, after fixed solar lawn lamp installs to the position that needs arbitrarily, sunlight direct projection on daytime is on its reflective top cover, solar panel on the top cover is just intensified, produce opto-electronic conversion, by controller constantly to charge in batteries, controller can control solar panel to storage battery overcharge and storage battery to the under-voltage discharge of the excess of cluster bulb, and controller can be controlled automatically when extraneous light luminance is lower than design brightness, automatically open the battery discharging circuit, storage battery is discharged to the cluster bulb, light bulb and send illumination, when extraneous light luminance is higher than design brightness, controller can also cut out the battery discharging circuit automatically, and open the charging circuit of solar panel automatically to storage battery, solar panel is constantly to charge in batteries, the periodic duty that keeps this Lawn lamp not stop.
As Fig. 1, be structural representation of the present utility model:
Wherein: (1) mains switch, (2) battery bracket, (3) controller, (4) reflection shield, (5) transparent panel, (6) LED cluster bulb, (7) bearing support, (8) reflective top cover, (9) solar panel, (10) lamp holder, (11) back panel wiring, (12) storage battery, (13) are lamp bracket fixedly
Be embodiment of the present utility model below
In the bottom of fixing lamp bracket (13) by battery bracket (2), stationary stroage battery (12), the output of storage battery (12) is connected with LED cluster bulb (6) by back panel wiring (11), and be connected with the output of controller (3) simultaneously, on back panel wiring (11), be connected to mains switch (1), mains switch (1) is installed in the fixedly bottom of lamp bracket (13), LED cluster bulb (6) is installed on the lamp holder (10), lamp holder (10) is installed in the centre of reflection shield (4), reflection shield (4) is fixed on the fixedly top of lamp bracket (13), transparent panel (5) is equipped with on its surface, controller (3) is installed in the below of reflection shield (4), the line of its input is connected on the solar panel (9) by bearing support (7), solar panel (9) is installed in the surface of reflective top cover (8), and bearing support (7) is fixedly lamp bracket (13) and reflective top cover (8) connect into an integral body.
During work fixedly lamp bracket (13) be installed in the place that needs, sunlight direct projection on daytime is on solar panel (9), the electric current of the intensified generation of solar panel (9) is through controller (3), be input to the output of storage battery (12), storage battery (12) is charged, storage battery (12) constantly is recharged, be in saturation condition, when the degree of illuminating in the external world is lower than the illumination of determining when designing, to the circuit the LED cluster bulb (6), lighted by LED cluster bulb (6) from storage battery (12) for the automatic connection of controller (3), and light is by the reflective surface of transparent panel (5) and reflective top cover (8), around being scattered in, illuminated the flower garden, the lawn.When the degree of illuminating in the external world is higher than the illumination of determining when designing, controller (3) cuts off the discharge circuit of storage battery (12) to cluster bulb (6) automatically, and connected the charging circuit of solar panel (1) simultaneously to storage battery (12), solar panel (1) produces electric current under the irradiation of the sun continues storage battery (12) is charged, the cluster bulb is lighted again automatically after the darkness, go round and begin again, solar energy flower garden lamp always operate as normal under the state that does not need any electric network source.Cut off battery feed usefulness when fixedly the mains switch of lamp bracket bottom is convenient to the utility model packed and transported, inoperative when operate as normal.
Its profile of fixedly lamp bracket (13) of the utility model indication can be the moulding of wide range of forms, but its internal structure all is identical.
The utility model does not need to excavate trench when work, do not need to bury underground pipeline, do not need to consume grid power, can be installed in any place that needs installation arbitrarily, install simple and convenient, without any operating cost, not needing special messenger's maintenance management when the back use is installed, is a kind of energy-conservation green product.
