An illumination device with a toning function in which possibility of moisture and dust intruding into the case is reduced with a simple mechanism is realized. The illumination device includes a light emitting element light source () mounted on a substrate inside the case unit (), an external gear-shaped fluorescent-substance plate () having a configuration in which a light emitting color of an applied fluorescent substance differs according to position and being arranged above the light emitting element light source () inside the case unit (), and an internal gear-shaped adjustment ring () arranged so as to mesh with the external teeth of the fluorescent-substance plate (), wherein the adjustment ring () is arranged to be positioned on the outer periphery of the main body under a lens dome (), and when the adjustment ring () is rotated, a relative positional relationship between a color distribution applied on the fluorescent-substance plate () and the light emitting element light source () is changed.

In an LED light bulb, an LED module and a lens are disposed on a fixing stage provided to a housing. The lens has a concave portion at its top end. The concave portion forms a reflecting surface which reflects part of outgoing light from the LED module to (i) first directions perpendicular to a front emission direction of the outgoing light or (ii) second directions leaning to a cap beyond the first directions. Due to diffusion effect of an optical cover, part of the light reflected by the lens is emitted backward (toward the cap). This realizes an LED light bulb that distributes light over an entire circumference and has high output as well as high light output ratio.

A receiver apparatushas a digital circuit portionthat converts a compressed digital signal outputted from a digital demodulating portioninto digital video and audio signals and a video/audio output circuitthat converts the digital video and audio signals outputted from the digital circuit portioninto analog video and audio signals. With this configuration, a video/audio processing IC for digital signal processing no longer needs to be mounted on the circuit board of a video display apparatus, and thus a receiver system can be realized with a video display apparatus having a simple configuration.

There is provided a switching circuit of a BS converter capable of assuring a high sensitivity. A BS tuner superimposes a band switching pulse signal on a power voltage when selecting a high band, and supplies the resulting signal to a BS converter. The BS converter amplifies a pulse signal selected by a filter circuit of a switching circuit by ten times in a differential amplifier, rectifies the resulting signal in a rectifying circuit, and compares the resulting signal with a reference voltage in a comparator circuit, thereby detecting the presence or absence of the band switching pulse signal. When the band switching pulse signal is detected, a high-band local oscillator is turned on by a drive circuit. When the signal is not detected, a low-band local oscillator is turned on. Thus, by amplifying by about ten times the band switching pulse signal having a voltage of about 0.6 V, a reception frequency band is switchedly selected with high accuracy.
