Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Referring to fig. 1, the photovoltaic display unit is a unit for displaying a predetermined pattern, which is a realistic pattern such as a character, an image, a letter, a trademark, etc., by lighting using electric energy generated by the photovoltaic module 1, and in the example shown in fig. 1, the predetermined pattern is "SOLIBRO".
The photovoltaic display unit includes a photovoltaic module (e.g., CIGS module) 1 for solar power generation and a lamp strip 2 for light emission. The lamp strip 2 is a strip of lamp (e.g., LED) assembled on a strip-shaped FPC (also called a flexible circuit board) or a PCB (called a strip because of its shape). The photovoltaic module 1 is electrically connected with the lamp strip 2 and is used for supplying power to the lamp strip 2.
The strip 2 is arranged at a lateral outer circumference 1a of the photovoltaic module 1, wherein the lateral outer circumference 1a of the photovoltaic module 1 can also be understood as the circumference of a lateral face of the photovoltaic module 1. The photovoltaic module comprises a glass layer 3 on the outer side and a chip layer 4 on the inner side, which are stacked on each other, and a part of the surface of the glass layer 3 adjacent to the chip layer 4 is formed with a receiving portion for filling with glue, which is conveniently realized on glass, and in fig. 1, the receiving portion is a frosted surface for receiving the glue. For example, the receptacle (i.e., the frosted surface) is in the shape of a predetermined pattern "SOLIBRO". For example, in fig. 1, the lower surface 3a (adjacent to the chip layer 4) of the glass layer 3 is formed with a frosted surface in the shape of "SOLIBRO". The receptacle is filled with a glue, which may be EVA or PVB, for example. Alternatively, the receiving portion may be a groove formed on the glass.
Based on the structure, the lamp strip is powered by solar energy to emit light, and the transmission of the light emitted by the lamp strip in different materials is different, so that the SOLIBRO character is displayed after sand blasting treatment.
The strip of light 2 may be arranged around the entire circumference of the lateral outer periphery of the photovoltaic module to make the light emission in all directions more uniform. In addition, in order to obtain better fixing and available space, the photovoltaic display unit may further include a rib 5, the rib 5 is also arranged around the whole circumference of the lateral outer periphery 1a of the photovoltaic module 1, the rib 5 has a clamping groove 5a, the cross-sectional shape of the clamping groove 5a may be, for example, U-shaped, and the shape of the clamping groove 5a is adapted to the shape of the lateral outer periphery 1a of the photovoltaic module and the shape of the strip 2, so that the lateral outer periphery 1a of the photovoltaic module and the strip 2 are clamped in the clamping groove 5 a. Here, according to an embodiment, can place lamp area 2 in the draw-in groove 5a of flange 5 earlier, then will attach the draw-in groove joint that has flange 5 in lamp area 2 to photovoltaic module's the lateral periphery 1a on, so can conveniently realize the fixed of lamp area 2, save space and fixed cost.
In practice, the photovoltaic module 1 may be electrically connected to the strip 2 via an energy storage element (for example, a storage battery, which is not shown), whereby the energy storage element may be charged in case of bright light and powered by the storage battery in case of dim light.
A method of manufacturing such a photovoltaic display unit is given below, comprising the steps of:
s1, forming a pattern opposite to the predetermined pattern on the sandblasted resist film; here, the sandblast resist film may be understood as a resist film for blocking or placing the remaining portion other than the predetermined pattern without being sandblasted. Generally, the sandblasting protective film is a water-gel composite protective film, and is mainly used for sandblasting and carving artistic glass and protecting the surface layers of other articles.
S2, placing the sandblasting protective film on the outer surface of the glass layer; so that the glass layer is subsequently sandblasted.
S3, performing sand blasting treatment on the outer surface of the glass layer with the sand blasting protective film; due to the existence of the sandblast resist, a sandblasted SOLIBRO font is formed in fig. 1.
S4, removing the sandblasting protection film; so that the SOLIBRO glyph is exposed.
S5, laminating the chip layer and the glass layer in a mode that glue is clamped between the outer surface of the glass layer and the chip layer; that is, after an adhesive is provided between the side on which the SOLIBRO-shaped frosting is formed and the chip layer, the glass layer (the side on which the SOLIBRO-shaped frosting is formed) is laminated with the chip layer. According to one embodiment, EVA, butyl is disposed between the chip layer and the glass layer. Here, the glue receptacle may be filled with EVA or PVB, the butyl being provided at the edge for sealing.
And S6, arranging the lamp strip on the lateral outer periphery of the photovoltaic module. That is to say, after the frosted layer is combined, the lamp strip 2 and the flange 5 are arranged. For example, a rib with a slot is provided, the strip is placed in the slot of the rib, and then the lateral outer periphery of the photovoltaic module is inserted into the slot of the rib.
The following explains the manufacturing steps of the photovoltaic display unit in an alternative description from an application point of view. The cell structure is chip + EVA + butyl rubber + toughened glass, and the manufacturing steps of the CIGS-LED assembly are as follows:
step one, determining a pattern to be displayed, and then engraving a reverse pattern on a sand blasting protective film with the same size as glass: exposing the pattern, adhering a sand blasting protective film on the upper surface of the glass, performing sand blasting treatment on the front toughened glass, removing the sand blasting protective film after the sand blasting treatment, and forming a frosted state on the surface of the toughened glass subjected to the sand blasting treatment.
And step two, laminating (the sand-blasting surface of the front toughened glass plate after sand blasting (namely the upper surface of the toughened glass plate) is inward, laminating through EVA, butyl rubber and the like, and after laminating, melting the EVA to fill the sand-blasting surface.
Placing the LED lamp strip in a PVC (polyvinyl chloride) clamping groove (which is equivalent to the clamping groove in the flange) in the step III; then, four sides of the assembly are embedded into the PVC clamping grooves, and the assembly and the PVC clamping grooves can be connected through structural adhesive.
Since the whole assembly can be divided into two areas (sand blasting and untreated) after the lamination is completed, the transmission difference of the light source of the LED strip between the sand blasting and untreated areas enables the pattern to be displayed. In addition, the display effect of the photovoltaic display unit is softer, and the illumination is more even.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
