Light reuse sheet, solar battery module, and light source module |
摘要 |
A light reuse sheet includes a reflective surface having an uneven configuration, the reflective surface in order to reflect light in a specific direction so as to cause light to be incident to a solar battery cell, the light being incident to a solar battery module, or in order to exit light in a specific direction by reflecting the light, the light being emitted from a light emitting element of a light source module. The reflective surface satisfies the following formula where a length in a horizontal direction of a solar battery cell or a light emitting element is represented by Lx; a length in a vertical direction of a solar battery cell or a light emitting element is represented by Ly; an angle formed between a direction of an uneven configuration of the reflective surface and an edge in a horizontal direction of the solar battery cell or the light emitting element is represented byφ; and maximum width of light which passes between adjacent solar battery cells and which is reflected by a light reuse sheet and is incident to a light receiving face of a solar battery cell or maximum width of light which is not emitted from a light emitting element in a specific direction and which exits in a specific direction by reflecting the light at a light reuse sheet is represented by A. f φ= 0 = Ly · cos φ- Lx · sin φ- A ( cos 2 φ- sin 2 φ) ( Formula 1 )
