Abstract: A photovoltaic module is provided. The photovoltaic module includes a solar panel, a reflective insulating element, and a plate. The reflective insulation element reflects the sunlight, and the reflected sunlight passes through the solar panel, which results in an enhancement of photovoltaic effects occurred in the solar panel. A gap is disposed between the plate and the reflective insulation element, forming a hollow layer to obstruct heat conduction between the reflective insulation element and the plate effectively. The power generating efficiency and thermal-insulating ability of the photovoltaic module provided in the invention are improved.

Abstract: The present invention discloses an improved LED structure and comprises: a LED chip; a wire; a packing mask; and a photocatalytic agent. The volume of an LED is smaller so as to be convenient for installation. Compared to a conventional LED with same power, the present invention increases the total contact surface area that contacts air, so that the functions of disinfection, deodorization, and mildewproofing can be effectively achieved.

Abstract: The present invention discloses an improved LED structure and comprises: a circuit brace, a bowl member; a light chip; a welding line; a packing mask; and a photocatalystic agent. The volume of an LED is smaller so as to be convenient for installment. Compared the present invention to a light tube with same power, the present invention can be added several LEDs in order to increase the curve surface area to contact air, so that the functions of disinfection, deodorization, and mildewproof can be effectively achieved.

Abstract: A window structure is provided, comprising a frame, a solar energy board, a plate and a heat isolation film. The solar energy board is disposed in the frame. The plate is disposed in the frame corresponding to the solar energy board, wherein an isolation chamber is formed between the plate and the solar energy board. The heat isolation film is disposed between the solar energy board and the plate, and divides the isolation chamber.
