[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 A green building with a light energy utilization device includes a steel structure main body and a roof. The steel structure main body can be composed of supporting beams, columns, and trusses, and the outer side of the supporting body is fitted with color steel plates, door panels, and other structures to form the steel structure building body. The traditional roof part also adopts a similar structure to the main body and is installed and fixed on top of the main body. However, in this application, the roof part can adopt a modular design and is composed of a top surface unit 10, a perforated panel 20, a sound absorber 30, a flexible photovoltaic panel 40, two sets of lighting units 50, multiple reinforcement units 60, and two sets of roof skin steel plates 70.

[0023] In this embodiment, the top unit 10 is composed of multiple frame arrays. The frames can be made by bending and welding steel plates or by casting. The inner cavity of each frame structure is through-holes, giving it a mounting groove 11. When the top unit 10 is assembled, each pair of adjacent frames can be connected and fixed to their adjacent sidewalls by fasteners such as bolts and rivets.

[0024] In this embodiment, a porous panel 20, fixedly connected to the top surface unit 10, can be provided in each of the multiple mounting slots 11 formed on the top surface unit 10. The porous panel 20 can be made by bending an aluminum alloy plate with multiple small holes on its surface, and has an opening at the bottom of the porous panel 20 so that the sound absorber 30 can be inserted into it. In addition, the top wall of the porous panel 20 covers the inner cavity of the mounting slot 11, and the sound absorber 30 fills the gap between the porous panel 20 and the bottom inner wall of the mounting slot 11. The sound absorber 30 can be made of porous foam as a pad. The numerous tiny pores distributed on the surface of the porous panel 20 have a pore diameter of 0.1-1 mm. High-frequency sound waves (>1000Hz) are directly absorbed by the pores and converted into heat energy through viscous resistance (sound wave vibration friction against the pore wall). Mid- and low-frequency sound waves (<1000Hz) penetrate the pores and form reflection-interference behind the plate, reducing sound energy through phase cancellation. The sound absorber 30 has an open-cell structure with continuous channels, and the elastic foam pad (such as polyurethane foam pad) has high damping characteristics, which can effectively absorb vibration energy. After the sound wave enters the foam, it gradually attenuates through multiple reflections and refractions (the tortuous path of the pores), and is eventually converted into heat energy. The porous aluminum alloy plate mainly absorbs high-frequency sound waves and reflects mid- and low-frequency sound waves. The porous foam pad absorbs the residual sound waves that penetrate the aluminum alloy plate, especially in the mid- and low-frequency range.

[0025] In this embodiment, a flexible photovoltaic panel 40 is bonded and fixed to the top of the porous panel 20. This flexible photovoltaic panel uses polymer materials such as polyimide (PI) and polyethylene terephthalate (PET) to replace the traditional glass substrate, achieving bendable and foldable characteristics. Furthermore, the flexible photovoltaic panel uses low-temperature co-sintering technology to laminate the battery layer, conductive layer, and substrate material. The flexible photovoltaic panel is more suitable for installation on irregularly shaped buildings such as wave-shaped and dome-shaped structures. The structure of the flexible photovoltaic panel 40 is existing technology and will not be described in detail here.

[0026] In this embodiment, two sets of lighting units 50 are fixedly connected to opposite sides of the bottom of the top unit 10, and each set of lighting units 50 consists of an outer frame 51, multiple partition plates 52, and multiple glass plates 53. The outer frame 51 is fixedly connected to the bottom of the top unit 10, and multiple partition plates 52 are formed at intervals on the inner side of the outer frame 51. Between every two adjacent partition plates 52, two glass plates 53 are provided that are fixedly connected to the outer frame 51 and the partition plates 52. The multiple partition plates 52 and multiple glass plates 53 divide the inner cavity of the outer frame 51 into several light-transmitting and closed cavities. Light can shine into the building through the glass plates 53. In addition, the multiple partition plates 52 and multiple glass plates 53 divide the inner cavity of the outer frame 51 into cavities, so that when sound waves are transmitted to the cavities, the vibration and friction of air molecules in the cavities are converted into heat energy, which can also reduce noise transmission.

[0027] In this embodiment, multiple reinforcing units 60 are spaced apart below the top surface unit 10, and each reinforcing unit 60 is fixedly connected to the top surface unit 10. The multiple reinforcing units 60 are used to assist in supporting the top surface unit 10. The bottom of the reinforcing unit 60 can be connected and fixed to the supporting beams, columns, or other structures in the main building structure using fasteners.

[0028] In this embodiment, both sets of roof skin steel plates 70 are connected and fixed to the top surface unit 10 and the lighting unit 50 by fasteners, and the two sets of roof skin steel plates 70, together with the top surface unit 10 and the two sets of lighting units 50, form a roof with an opening at the bottom.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
