【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The vehicle-mounted lamp (1) is a lighting device such as a fog lamp that is attached to the vehicle afterwards, and is mounted on the front or upper part of the vehicle. The structure of the on-vehicle lamp (1) is general, the lamp (1a) is installed inside, and it is connected to the relay section (2) by wiring through the socket (1b). The lamp (1a) is turned on and off by the relay operation of (2).

The relay section (2) is composed of a relay device (2a) and a relay control circuit (2b), and is installed in the engine room of the vehicle. The relay device (2a) is connected to the battery (10) of the vehicle via the power supply line (10a), and power is supplied from here. The main part of the relay control circuit (2b) is composed of a reception IC (7), which is connected to the relay device (2a) and controls the energization of the coil (8) of the relay device (2a).

The operation switch section (4) is installed in a position near the driver's seat in the vehicle where it is easy to operate. The panel is provided with an ON switch (4a) and an OFF switch (4b) (of course, one switch may be used to perform the ON / OFF operation), and the transmission IC (4f) is used. The pulse train signal corresponding to each switch is output from the transmission IC (4f), and the reception IC (7b) of the relay control circuit (2b) of the relay section (2) is transmitted via the signal transmission section (3). ). (4e) is a power supply (battery in this embodiment) for operating the operation switch section (4).

The signal transmission section (3) is composed of light emitting / receiving elements (3a) (3b) and a control signal line, and connects the relay section (2) and the operation switch section (4). . The light emitting / receiving elements (3a) (3b) are bonded and arranged inside and outside through the window glass (5) of the vehicle, in this embodiment the windshield (5), by an adhesive means such as a double-sided tape. There is.

When the ON switch (4a) of the operation switch section (4) is pressed, a pulse train signal corresponding to this is output from the transmission IC (4f), and the light projecting element (3a) (light emitting diode in this embodiment) Emits light in response to the pulse train signal. An infrared light emitting element is generally used as the light emitting element (3a) so that it does not hinder driving.

The light of the light projecting element (3a) passes through the window glass (5), is detected by the light receiving element (3b), and is converted into an electric signal. This electric signal is input to the reception IC (7) of the relay control circuit (2b). The receiving IC (7) discriminates from the input electric signal that the power-on switch (4a) has been pressed, applies current to the coil (8) of the relay device (2a) to excite it, and relay contact (9) ) To contact. As a result, a current flows from the battery (10) through the relay contact (9) to the lamp (1a) of the vehicle lamp (1), and the lamp (1a) is turned on.

When it is desired to turn off the lamp (1a), when the switch (4b) on the power-off side is pressed, an off pulse train signal is output from the transmission IC (4f), and the light emitting element (3a) outputs the pulse train signal as described above. It emits light corresponding to the number. The light of the light projecting element (3a) passes through the window glass (5), is detected by the light receiving element (3b), is converted into an electric signal, and is then input to the receiving IC (7). The receiving IC (7) discriminates from the input electric signal that the power off switch (4b) has been pressed, shuts off the current flowing through the coil (8) of the relay device (2a), and disconnects the relay contact ( 9) Open. As a result, the current flowing from the battery (10) through the relay contact (9) to the lamp (1a) is cut off and the lamp (1a) is turned off.

It is preferable to use the receiving IC (7) having a state holding function. In this case, once a signal is input, the state (power ON state) is maintained until the next signal is input. Or the power is turned off), the light emitting element (3a) need only emit light at the moment when the switch is pressed, and thus the power consumption on the operation switch (4) side is small and the internal battery length is long. It can be used for a period of time. Further, the space between the light projecting element (3a) and the light receiving element (3b) does not need to be adhered to the window glass (5) as described above, and may be within a range that light can reach. The light of the light projecting element (3a) may be something other than infrared rays, such as visible rays or ultraviolet rays.

3 and 4 are drawings corresponding to “Claim 4”. The lighting / extinguishing device of the vehicle lamp according to claim 1 is used as a lamp (1a) of the vehicle lamp (1). This is an example in which a voltage control circuit (2c) for controlling the applied voltage and applied voltage changing switches (4c), (4d) are added. According to this, when the applied voltage changing switch (4c) or (4d) is pressed according to the circumstances around the vehicle, for example, when the fog is thick or not so much, the pulse train signal corresponding to this is the same as described above. Is output from the transmission IC (4f), the light emitting element (3a) emits light in response to the pulse train signal, and the light receiving element (3b) detects it through the window glass (5) and converts it into an electric signal. Input to the reception IC (7) of the relay control circuit (2b). The receiving IC (7) discriminates from the inputted electric signal that either the applied voltage changing switch (4c) or (4d) is pressed, and controls the voltage control circuit (2c) to control the lamp (1a). Switch the voltage applied to. As a result, the brightness of the lamp (1a) can be adjusted according to the surroundings of the vehicle. The applied voltage changing switches (4c) and (4d) are not limited to the two-step switching, and a large number of switches may be provided to have a multi-step switching, or a stepless switching like a volume may be used. .

Next, regarding the lighting / extinguishing device of the second vehicle lamp (1) shown in “claim 2,” only the difference from “claim 1” will be briefly described. In this case, the transmitting / receiving antennas (3a) (3b) are replaced by the transmitting / receiving antennas (3a) (3b), and the ON signal or OFF signal is transmitted between the transmitting / receiving antennas (3a) (3b). Will be exchanged as. The transmitting and receiving antennas (3a) and (3b) also functionally match the light emitting and receiving elements (3a) and (3b), so the same reference numerals are used in the description. The partition wall (6) may be any portion as long as it separates the inside and the outside of the vehicle, but in this embodiment, it shows the portion separating the engine compartment and the driver's seat.

Further, the lighting / extinguishing device of the third vehicle-mounted lamp (1) shown in “Claim 3” will be briefly described with only the differences from “Claim 1”. High frequency vibration generator (3a) and vibration detector (3b) are used instead of 3a) and (3b) .A piezoelectric element (not shown) is built in the high frequency vibration generator (3a). When an electric signal is output from the transmission IC (4f) by pressing the ON switch (4a), the piezoelectric element generates a specific high frequency vibration in response to this, and the partition wall (6) (iron plate) or window glass (5 Is transmitted to the vibration detector (3b). The high frequency vibration transmitted to the vibration detector (3b) is converted into an electric signal and input to the reception IC (7). Since the high frequency vibration generator (3a) and the vibration detector (3b) also functionally match the light emitting / receiving elements (3a) (3b), the same reference numerals are used in the description.
