    • The semiconductor integrated circuit includes: a pair of antenna terminals; a rectifier; a source-voltage terminal; a shunt regulator; a series regulator. When the voltage of the inside source line rises to or above a first set voltage, the shunt regulator passes a pull-down current through a pull-down transistor. When the voltage of the inside source line drops to or below the second set voltage, the series regulator passes a pull-up current through a pull-up transistor. The first set voltage is set to be higher than the second set voltage in voltage level. With the semiconductor integrated circuit, the competition of actions of the two regulators is prevented. The semiconductor integrated circuit is arranged to work in contact and noncontact operation modes, and a stable source voltage can be supplied to an internal circuit thereof.

    • Light which tries to enter a diffuser plate 3 at an angle which exceeds an angle at which a percentage of reflected light increases rapidly (that is, the incidence angle θ=70 degrees) is all reflected by a reflecting surface 21 and then enters the diffuser plate 3. Therefore, a pseudo light source is formed by light which was collected near a connection point between adjacent reflecting surfaces 21 out of the emitted light of the discharge lamps 1. So, the brightness between the adjacent discharge lamps 1 is increased, and it is possible to reduce unevenness in brightness. Furthermore, since the discharge lamp 1 is housed inside the reflecting surface 21 whose cross-sectional shape is a parabola, it is possible to reduce the distance between a reflecting plate 2 and the diffuser plate 3, as compared with the prior art, and to reduce the thickness dimension in the anteroposterior direction.
