Abstract

PURPOSE:To improve external appearance and to facilitate mounting work performance by integrating a room lamp housing, an antenna part and its circuit and mounting the antenna on a hole made in a room of a vehicle with the radio wave radiating face of the antenna directed outward. CONSTITUTION:A lamp 30 and a lens 32 are mounted on a housing 3, a hole is made in an outer plate 1 of a vehicle and the housing 3 is fitted therethrough. The housing 3 is fitted with a circuit part 6 and an antenna part 5 integratedly. Since the antenna part 5 is required to be coupled externally electromagnetically, the antenna is covered by a radome 4 made of a material offering excellent electromagnetic wave transmittivity. Since a power wire 9 and a signal wire 8 are wired between the outer plate 1 and the inner member, it offers excellent external appearance Moreover, since the power supply 9 is used in common for the room lamp and the circuit part 6, the quantity of wiring is less.

The housing 3 includes a lamp 30. A lens 32 is installed, and is fitted into a hole made in the outer panel 1 of the vehicle. A circuit section 6 and an antenna section 5 are further integrated and attached to the housing 3. The antenna section 5 is covered with a radome 4 made of a material with good electromagnetic wave permeability in order to electromagnetically couple with the outside. The power supply m9 and signal line 8 are wired between the outer panel 1 and the interior material, which is convenient for aesthetics, and since the power supply 9 is shared between the room lamp and the circuit section 6, there is less wiring. I'll try it.

Power is supplied to the loop lamp 30 from a battery, and a switch 31 controls the grounding of the vehicle body. Power is constantly supplied to the circuit section 6. Normally, when dealing with minute signals, the power supply current is small, so there is no problem even if the power is always turned on like this. If the power supply current cannot be ignored, the power supply and signal can be multiplexed and passed through the same cable 8 as shown in FIG. 10 is a choke coil for blocking high frequencies, and 11 is a capacitor for direct current blocking or high frequency bypass. By using this circuit, the power supply of the circuit section 6 can be controlled in conjunction with the power supply of the main body to which the antenna device is connected, and wasteful power consumption can be avoided.
