The solar panel 2, the control circuit board and the polymer lithium battery 4 form the solar panel subsystem. Due to the variability of natural climate, the solar panel 2 is preferably a polycrystalline silicon panel. In rainy days with weak sunlight, the power generation efficiency of the polycrystalline silicon solar cell is better than that of monocrystalline silicon and amorphous silicon.

The rechargeable battery is preferably a polymer lithium battery 4, and the lithium battery can resist high temperature and low temperature according to the climatic characteristics of the delivery area.

Lithium batteries currently use polymer lithium batteries. The lithium polymer battery using the solid polymer electrolyte has the characteristic of ultra-thinness in shape, the theoretical minimum thickness can reach 0.5mm, and the characteristics of arbitrary shape, arbitrary area and the like. The battery has the characteristic of greatly improving the flexibility of the battery shape, so that the battery can be made into any shape and capacity better.

Compare with current product, its advantage lies in:

small volume and light weight. Structurally, the design that the transparent acrylic panel covers the solar cell panel is adopted, peripheral parts of a product are simplified, and the thickness of the product is reduced. Most of the whole product is made of organic materials, so that the overall weight is reduced.

Energy saving, easy to assemble, the maintenance is simple. Because the solar cell is adopted, the service life is long. At present, the service life of the solar battery can reach 8-10 years, the service life of the rechargeable battery is close to 10 years, and the service life of the LED light source is also close to 10 years, so that matched electric facilities are not needed. Due to the fact that the modular design is adopted in the structure, all parts are relatively independent, and therefore the workload and difficulty of maintenance operation are reduced, and maintenance cost is reduced.

The environmental adaptability is strong. Aiming at the defects of several types of indicating boards commonly seen in the current market, a novel character silk-screen printing process is invented, and three high-display effects of reflection, noctilucence and self-luminescence are combined. Firstly, silk-screen printing transparent finish paint of the reflective paint in the groove on the front side of the noctilucent and reflective panel, and pouring long afterglow highlight noctilucent paint in the groove on the back side. Under the irradiation of the car lamp at a distance, the reflective paint and the luminous paint are combined to play a role, so that characters on the panel are highly displayed, and the effect of improving the brightness is achieved. The luminous paint is treated by adopting a pouring method, so that the thickness of the paint film is increased, the larger the thickness of the luminous paint film is, the more light energy is absorbed, the higher the brightness is, and the longer the afterglow time is. The two painting process technologies are adopted to make up for the defect that the solar cell system is insufficient in power storage in continuous rainy days.

And (4) modular design. Due to the adoption of the modular design, the product has a high-grade, a medium-grade and a low-grade series product.

The component can be used in the fields of families (house plates), businesses (signboards), traffic (guideboards), public facilities (indication plates) and the like due to the dual functions of the reflective plate and the luminous plate.

2. The method includes the steps of manufacturing a small-sized closed light box by using the existing lighting technology, self-illuminating at night and illuminating without the aid of vehicle light, wherein the small-sized closed light box has the disadvantages of large early investment, high construction cost, large later maintenance workload and the like.

3. And (5) product combination. Another advantage of the modular design is the finished assembled combination. On a bottom plate, a plurality of personalized effects can be combined by arranging and combining the single finished products (solar digital cards, character cards, pattern cards and lamp cards).

And (5) upgrading the space. According to different market demands, the product can upgrade control circuit components, and has the functions of flow monitoring, wireless communication and remote maintenance alarm. With the technological progress, solar photovoltaic modules with higher conversion efficiency, graphene rechargeable batteries with higher storage density, longer afterglow luminous materials with higher brightness, miniaturization of intelligent products and miniaturization of electronic devices, various components can be upgraded continuously.

The pattern can cover a small amount of partial solar chips, but through testing, the noctilucent paint film is in a semitransparent state under sunlight, and sunlight can partially penetrate through the noctilucent paint film, so that the covered solar chips can still work. While most of the uncovered solar chips are sufficient to power the rechargeable battery. Because the solar chip with a special formula is adopted, the hot spot effect is not generated.

2. The special ultra-bright flat-end concave large chip side light lamp bead is selected and placed in an organic glass drill hole, the high-bright side light is emitted into an organic glass body and reflected out from the bottom of a rough luminous paint groove to penetrate through a glass bead reflective surface paint film, and the high-display effect is achieved.
