[0045] A solar LED light panel, comprising:

[0046] substrate,

[0047] LED lamps are arranged on one side of the substrate, and there are gaps between the plurality of LED lamps;

[0048] A solar film is provided on a side of the substrate close to the LED; a direction perpendicular to the substrate is recorded as a first direction, and when viewed along the first direction, the solar film covers the gap;

[0049] A storage battery is arranged on a side of the substrate away from the LED lamp; the storage battery is electrically connected to the LED lamp and the solar film respectively.

[0050] By setting the LED lights and the solar film on the same side of the substrate and covering the gaps between multiple LED lights with the solar film, the gaps between the LED lights are fully utilized for solar power generation, and the LED lights and the solar film are highly integrated. During the day, sunlight shines on the solar film to generate electricity, which is stored in the battery; at night, the battery supplies power to the LED lights, and because the solar film covers the gaps between multiple LED lights, the light emitted by the LED lights can also be used for solar power generation, realizing energy recycling and reuse.

[0051] Please refer to Figure 1 - Figure 5 In one embodiment of the present invention, a solar LED light panel 100 is provided. The solar LED light panel 100 includes: a substrate 10, a solar film 30, a driver chip 40, and a battery 50.

[0052] The LED lamps 20 are disposed on one side of the substrate 10, and there are gaps between the plurality of LED lamps 20. The solar film 30 is disposed on a side of the substrate 10 close to the LEDs.

[0053] In order to make full use of the gaps between the LED lamps 20, the direction perpendicular to the substrate 10 is recorded as the first direction F1. When observed along the first direction F1, the solar film 30 covers the gaps to increase the coverage area of ​​the solar film 30 on the substrate 10 and increase the total power generation.

[0054] The battery 50 is disposed on a side of the substrate 10 away from the LED lamp 20 ; the battery 50 is electrically connected to the LED lamp 20 and the solar film 30 , respectively.

[0055] Among them, the substrate 10 is provided with a wire loop, the LED lamp 20 is arranged on the front side 11 of the substrate 10 and connected to the wire loop; the solar film 30 is arranged on the front side 11 of the substrate 10 and connected to the wire loop, and the battery 50 is arranged on the back side 12 of the substrate 10 and connected to the wire loop.

[0056] In one embodiment, see Figure 1 and Figure 2 The solar film 30 has a lamp hole 31 formed through it, and the LED lamp 20 is disposed within the lamp hole 31. Both the solar film 30 and the LED lamp 31 are connected to a wiring circuit through the front surface 11 of the substrate 10. When light shines on the solar film 30, the generated current is stored in the battery 50 through the wiring circuit. When the LED lamp 20 is in operation, the battery 50 supplies energy to the LED lamp 20 through the wiring circuit.

[0057] In another embodiment, see Figure 3 and Figure 4 The LED lamp 20 is located on the side of the solar film 30 facing away from the substrate 10. The solar film is connected to the electrical circuit through the front surface 11 of the substrate 10. The LED lamp 20 is connected to the side wiring, bypassing the solar film 30 and connecting to the electrical circuit. When light shines on the solar film 30, the generated current is stored in the battery 50 through the electrical circuit. When the LED lamp 20 is in operation, the battery 50 supplies power to the LED lamp 20 through the electrical circuit.

[0058] The substrate 10 is used to mount the LED lights 20 and the solar film 30. Electrical wiring is routed between the front 11 and back 12 of the substrate 10, forming a circuit between the electrical components on the front 11 and the back 12. In this embodiment, the LED lights 20 and solar film 30 are mounted on the front 11 of the substrate 10, while the driver chip 40 is mounted on the back 12.

[0059] Specifically, a plurality of first electrical contacts 111 and a plurality of second electrical contacts 112 are provided on the front surface 11 of the substrate 10 , and the first electrical contacts 111 and the second electrical contacts 112 are connected to a circuit.

[0060] The LED lamp 20 is disposed on the front surface 11 and connected to the electrical wiring loop. The LED lamp 20 is electrically connected to the first electrical contact 111, thereby connecting to the electrical wiring loop. Each LED lamp 20 may correspond to one first electrical contact 111, or each LED lamp 20 may correspond to multiple electrical contacts. In this embodiment, each LED lamp 20 is connected to the wiring loop through one first electrical contact 111.

[0061] The solar film 30 is positioned on the front surface 11 of the substrate 10 and connected to the electrical circuit. It is also electrically connected to the second electrical contact 112. A lamp hole 31 is formed through the solar film 30, and the LED lamp 20 is positioned within the lamp hole 31. When sunlight shines on the solar film 30, the generated current enters the electrical circuit and is supplied to the LED lamp 20. This integrates the LED lamp 20 and the solar film 30 on the same surface of the substrate 10. This eliminates the need for users to set up a separate solar panel when using the solar panel, improving the integration of the solar panel.

[0062] Furthermore, to connect the LED lamp 20 and the solar film 30 to the electrical wiring circuit, a first electrical contact 111 and a second electrical contact 112 are provided on the front surface 11 of the substrate 10. The first electrical contact 111 is used to connect to the LED lamp 20, and the second electrical contact 112 is used to connect to the solar film 30. The first electrical contact 111 is located within the lamp hole 31. The LED lamp 20 passes through the lamp hole 31 and connects to the first electrical contact 111. The solar film 30 covers the second electrical contact 112. The second electrical contact 112 is directly electrically connected to the surface of the solar film 30 where it contacts the LED lamp 20, thereby connecting the LED lamp 20 and the solar film 30 to the electrical wiring circuit. When sunlight shines on the solar film 30, the generated current enters the circuit through the first electrical contact 111 and is supplied to the LED lamp 20 through the second electrical contact 112.

[0063] Furthermore, the solar LED light panel 100 also includes a driver chip 40 and a battery 50. Both the driver chip 40 and the battery 50 are located on the back side 12 of the substrate 10, thereby allowing the front side 11 of the substrate 10 to face the sun. The back side 12 of the substrate 10 is used to mount other electronic components. The driver chip 40 is located on the back side 12 of the substrate 10 and connected to a wiring loop, thereby electrically connecting to the first electrical contact 111 and the second electrical contact 112, respectively. The battery 50 is located on the back side 12 of the substrate 10 and connected to a wiring loop, thereby electrically connecting to the driver chip 40.

[0064] Specifically, see Figure 3 The solar film 30 is connected in parallel with the LED lamp 20 and the battery 50 in the wire loop. The current generated by the solar film 30 can be used directly to power the LED lamp 20, and can also be used to charge the battery 50. When the power of the LED lamp 20 is not high and there is sufficient light, the current generated by the solar film 30 can be used to power the LED lamp 20 and charge the battery 50 at the same time. When it is rainy or at night, the power of the battery 50 can be used to power the LED lamp 20.

[0065] Furthermore, since the solar film 30 and the LED lamp 20 are integrated on the same surface of the substrate 10, the solar film 30 can not only absorb sunlight to generate electricity, but also absorb the light of the LED lamp 20 and convert it into electricity. In this embodiment, the wavelength of the light wave absorbed by the solar film 30 is recorded as L, and the wavelength of the light wave emitted by the LED lamp 20 is recorded as W, satisfying the relationship:

[0066] 460nm<W<636nm;

[0067] 400nm<L<800nm.

[0068] The solar film 30 uses a material with an absorption wavelength range of 400nm < L < 800nm, such as copper indium gallium selenide. The LED lamp 20 uses an LED with an emission wavelength range of 460nm < W < 636nm. For example, blue, green, yellow-green, yellow, yellow-orange, and red LEDs fall within this range. Thus, while the light panel absorbs sunlight to generate electricity, it also recycles the light energy from the LED lamp 20 into electrical energy for use by the LED lamp 20.

[0069] Furthermore, the material of the solar film 30 is one of cadmium telluride, copper indium gallium selenide, amorphous silicon, and gallium arsenide.

[0070] Furthermore, the LED lamps 20 are disposed within the lamp holes 31. A direction perpendicular to the front surface 11 is designated as a first direction F1. Adjacent LED lamps 20 are spaced apart along the first direction F1. This is equivalent to surrounding each LED lamp 20 with a solar film 30. This fully utilizes the planar area between the LED lamps 20, maximizing the coverage of the solar film 30 and increasing the total amount of solar power generated. Furthermore, the light emitted by each LED lamp 20 is absorbed by the surrounding solar film 30, allowing the solar film 30 to fully absorb the light energy of the LED lamps 20.

[0071] Furthermore, in order to ensure that the light from the LED lamp 20 can fully illuminate the solar film 30 and enable the solar film 30 to fully recycle and utilize the light energy released by the LED lamp 20, the solar film 30 includes: a first surface 32 and a second surface 33. The first surface 32 is in contact with the front surface 11. The second surface 33 faces away from the front surface 11, and the second surface 33 is directly opposite to the first surface 32. The LED lamp 20 includes: a bottom surface 21 and a top surface 22. The bottom surface 21 is in contact with the front surface 11. The top surface 22 faces away from the front surface 11, and the top surface 22 is directly opposite to the bottom surface 21. The first surface 32 is connected to the second electrical contact 112, and the bottom surface 21 is connected to the first electrical contact 111.

[0072] The height from the second surface 33 to the front surface 11 is denoted as H, and the height from the top surface 22 to the front surface 11 is denoted as T, satisfying the relationship:

[0073] H<T.

[0074] The top surface 22 of the LED lamp 20 is higher than the thickness of the film, so that the light emitted by the LED lamp 20 can be irradiated from a high position to the solar film 30 at a low position.

[0075] Furthermore, in order to prevent the LED lamp 20 from blocking the sunlight when the sunlight illuminates the front surface 11 of the substrate 10 , a slope 23 is provided on the LED lamp 20 in this embodiment.

[0076] One end of the inclined surface 23 is connected to the second surface 33, and the other end is connected to the top surface 22. When viewed along the first direction F1, the width of the top surface 22 of each LED lamp 20 is denoted as a, and the width of the bottom surface 21 of each LED lamp 20 is denoted as b, satisfying the relationship:

[0077] a<b.

[0078] Therefore, the solar light can be directly irradiated onto the surface of the solar film 30 along the inclined surface 23 , thereby improving the efficiency of the solar film 30 in absorbing solar light.

[0079] In this way, by arranging the LED lamps 20 and the solar film 30 on the same side of the substrate 10, and covering the gaps between the multiple LED lamps 20 with the solar film 30, the gaps between the LED lamps 20 are fully utilized for solar power generation, and the LED lamps 20 and the solar film 30 are highly integrated. During the day, sunlight shines on the solar film 30 to generate electricity, which is stored in the battery 50; at night, the battery 50 supplies energy to the LED lamps 20, and since the solar film 30 covers the gaps between the multiple LED lamps 20, the light emitted by the LED lamps 20 can also be used for solar power generation, realizing energy recycling and reuse.

[0080] The above-described embodiments merely represent several embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
