A cyclonic separator and a vacuum cleaner which efficiently separates dust, collect the dust without re-scattering it and make low noise are provided. In a primary cyclone portion 10, a primary swirl chamber 12 swirls air containing dust sucked from a primary inlet 11, and thereby, separates a first dust and a second dust from the air containing dust to collect them respectively in a zero-order dust case 114 which is provided at a side of the primary swirl chamber 12 and communicates with a zero-order opening portion 113 provided at a side wall, and a primary dust case 14 provided at a lower side of the primary swirl chamber 12. In a secondary cyclone portion 20, a secondary inlet 21 with an opening area smaller than that of a primary outlet body 15 sucks air exhausted from the primary outlet body 15, a secondary swirl chamber 22 swirls the first air to separate the second dust which is finer than the first dust from the first air to collect the second dust in a secondary dust case 24 provided at a lower side of the secondary swirl chamber 12. With regard to the cyclonic separator with such a configuration, the zero-order dust case 114 is formed to cover at least a part of the secondary cyclone portion 20.

The present invention provides a solar cell module which has high design freedom and can be easily manufactured at low cost. A solar cell module (10) includes (i) a light guide plate (1), (ii) a fluorescence-dispersed film (2) in each of which a fluorescent substance is dispersed and which is adhered to respective at least one surface of the light guide plate (1), and (iii) a solar cell element (3) which is provided on another surface of the light guide plate (1) which another surface being perpendicular to the at least one surface. Therefore, it is not necessary to prepare a light guide plate in which a fluorescent substance is dispersed. Moreover, it is possible to arbitrarily pattern the fluorescence-dispersed film (2) or to stack the fluorescence-dispersed films (2).

A light-controlling element includes an illumination unit capable of controlling an amount of emitted light, and a light guide body on which the light emitted from the illumination unit is incident. The light guide body has a function of propagating the light while totally reflecting the light inside the light guide body, and the light guide body has a function of propagating the light emitted from the illumination unit at a plurality of different propagation angles inside the light guide body. The light guide body includes a plurality of light extraction regions having a function of extracting the light to the outside. At least two of the plurality of light extraction regions have different incidence angle ranges in which the light is capable of being extracted to the outside.

A solar cell unit (100) of the present invention includes (i) a fluorescence converging plate (2) that contains fluorescent materials (6) for absorbing invisible light and then emitting invisible light and (ii) a solar cell (4) provided on an end surface (2a) of the fluorescence converging plate (2) so as to have a light receiving surface which faces the ends surface (2a). When the fluorescence converging plate (2) is irradiated with external light, the fluorescent materials (6) emit invisible light which is then reflected in the fluorescence converging plate (2) and thereafter converged onto the end surface (2a). The solar cell (4) carries out electric power generation by use of fluorescence converged onto the end surface (2a) of the fluorescence converging plate (2). Conversely, visible light, with which the fluorescence converging plate (2) is irradiated, is transmitted through the fluorescence converging plate (2) without being absorbed by the fluorescent materials (6). The invisible light emitted from the fluorescent materials (6) is ultraviolet light or infrared light, and is therefore invisible to human eyes. This causes the fluorescence converging plate (2) to be perceived as having color close to transparent in a case where the fluorescence converging plate (2) is observed from a side opposite from a main surface irradiated with the light.

A solar cell module (1) disclosed herein includes a solar cell (2), a fluorescence condensing plate (3), and a reflecting plate (4). The solar cell (2) is provided on at least a portion of at least one of end surfaces (that is, intersecting surfaces each intersecting with a light-obtaining surface) of the fluorescence condensing plate (3). At least one of two mutually opposite portions on each of which the solar cell (2) is absent has a bent surface. The reflecting plate (4) is provided on a surface of a portion on which the solar cell (2) is absent. With this arrangement, light that is guided toward any flat section or zigzag section on which the solar cell (2) is not placed is reflected by the reflecting plate (4) to ultimately reach the solar cell (2).

A solar cell module (10) includes: a low refractive index material layer (1) provided on an object (4); a high refractive index material layer (2), provided on the low refractive index material layer (1), which has a higher refractive index than the low refractive index material layer (1); and a solar cell element (3) provided on that surface of the high refractive index material layer (2) which intersects that surface (counter surface facing the low refractive index material layer (1)) of the high refractive index material layer (2) which is in contact with the low refractive index material layer (1). Further, the high refractive index material layer (2) contains a fluorescent material dispersed therein. Thus, light guided through the high refractive index material layer (2) is reflected at the interface between the high refractive index material layer (2) and the low refractive index material layer (1) and the interface between the low refractive index material layer (1) and an air layer, and is efficiently focused onto the solar cell element (3). This makes it possible to inexpensively and easily produce a solar cell module that has a high degree of freedom in design and that can be installed on a curved surface etc. without limitations of installation locations.
