Description

A kind of LED solar module

Technical field

The utility model relates to a kind of LED solar module, and promptly a kind of LED and the integrated assembly of solar cell belong to the photovoltaic generation applied technical field.

Background technology

In recent years, solar energy has received increasing concern as a kind of renewable new forms of energy of cleaning, and it is used also more and more widely, and one of them most important applications is exactly a photovoltaic generation.The elementary cell of solar energy power generating is a solar cell, in concrete application, normally a plurality of solar battery sheets is constituted solar modules, and then each solar module is coupled together integrant electric current output.

Present widely used solar module is mainly conventional monocrystalline silicon, polysilicon and film assembly, because the particularity of photovoltaic generation, solar components only possesses the single function of generating by day, and can not bring into play any function owing to there is the irradiation of sunlight assembly at night.LED uses very extensive in night Landscape Lighting and outdoor advertising shows owing to have that energy consumption is low, luminous efficiency is high and advantage such as long service life.Solar module and LED are combined, just can make its generating on daytime, the function of performance illumination in evening not only can reduce cost, and can reduce occupation space, has very high benefit.

But in existing technology, major part is separated use with solar components and LED, with the example of assembly and the direct integrated application of LED seldom.Application number is that 200710170914.2 Chinese patent specification discloses a kind of novel solar component, this assembly is made up of solar cell, led chip and nano cell, although it can realize the lighting function of assembly, but, make this component process complexity because nano cell is encapsulated in assembly the inside; And the stored energy capacitance of nano cell is limited, can't guarantee that LED is luminous for a long time; If nano cell breaks down, also be difficult to keep in repair.Application number is that 200810018900.3 Chinese patent specifications disclose a kind of laminating integral crystalline silicon solar energy photovoltaic device and production method thereof, led light source is welded on the two-sided copper-plated electronic circuit board in this kind assembly, and be stained with funnelform reflection shield around the led light source to improve light efficiency and luminous intensity, though reached that solar energy photovoltaic device and led light source is integrated, but it is complicated that this kind process still shows, and only be fit to the small-power subassembly product.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of LED solar module, be the integrated generating of a kind of solar cell and LED, illuminator, can realize that solar module generates electricity by day, can pass through the built-in long-time uniformly light-emitting of LED again, realize the function of night illumination.

In order to address the above problem, the utility model provides a kind of LED solar module, comprise and somely be cascaded and be arranged on solar battery sheet between an EVA layer and the 2nd EVA layer, the gap of described solar battery sheet is provided with some paster LEDs, described paster LED links together with lead, the outside of the one EVA layer is provided with glass, the outside of the 2nd EVA layer is provided with transparent back panel, the outside of described transparent back panel is provided with the LED light guide plate, and this solar module outside also is provided with controller and the storage battery that is connected with lead with paster LED.

Further improving is also to be provided with the 3rd EVA layer between described transparent back panel and the LED light guide plate.

Further, described glass can be preferably low iron ultrawhite toughened glass.

Further, described transparent back panel material is TPT, PET or glass.

Further again, described LED light guide plate is that transparent material is made.

The operation principle of above-mentioned solar module is: assembly produces electric energy by absorbing sunlight by day, and the part of this electric energy charges a battery by the controller in the external circuit control structure, and another part then flows to other load; Adopted transparent backboard and transparent light guide plate owing to assembly in addition, so assembly also has the function of printing opacity by day.At night, storage battery is powered to LED by controller, and the light transmission transparent back panel that LED sends evenly derives light by the LED light guide plate under the backboard again, the effect of seeing from the outside is the back side light guide plate uniformly light-emitting of solar module, thereby assembly plays the effect of night illumination and decoration.

A kind of LED solar module of the present utility model has been realized the integrated of solar cell and LED effectively, and than prior art, its beneficial effect is:

(1) this modular construction is simple, and is easy to make, utilizes existing assembly production equipment can realize the LED solar module;

(2) integrated by solar cell and LED expanded assembly function, both had the function of generating, can also be used for luminous lighting simultaneously, saved occupation space;

(3) introducing of light guide plate makes the assembly more even light emission, and light efficiency is higher, thereby this assembly is very suitable for the night illumination and the decoration in fields such as daylighting ceiling, bicycle shed, curtain wall.
