    • 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.
    • 本发明的太阳能电池单元(100)包括:(i)含有用于吸收不可见光并随后发射不可见光的荧光材料(6)的荧光会聚板(2),和(ii)设置在 荧光会聚板(2)的端面(2a),以具有面向端面(2a)的受光面。 当荧光收敛板(2)被外部光照射时,荧光材料(6)发射不可见光,然后在荧光会聚板(2)中反射,然后会聚到端面(2a)上。 太阳能电池(4)通过会聚在荧光会聚板(2)的端面(2a)上的荧光进行发电。 相反,荧光收敛板(2)照射的可见光透过荧光会聚板(2)而不被荧光材料(6)吸收。 从荧光材料(6)发出的不可见光是紫外光或红外光,因此对于人眼是不可见的。 这样,在从与照射光的主面相反的一侧观察荧光收敛板(2)的情况下,荧光收敛板(2)被感知为具有接近透明的颜色。

    • An emitting direction control apparatus for a lamp is provided with: a driver for deflecting an emitting direction for a lamp; and a controller that control the driver to perform a deflection. The controller includes an initialization function, for setting, at an initial position, a stepping motor that serves as a driving source for the driver. The initialization function detects a first current positional angle for the stepping motor; when the first current positional angle is greater than a reference angle, rotates the stepping motor in a bumping direction at a high speed until the reference angle is reached; after the reference angle has been reached, rotates the stepping motor to a bumped position an initial number of steps at a low speed; and after the bumped position has been reached, rotates the stepping motor in the reverse direction a predetermined number of steps and sets the stepping motor in the initial position.
