Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is installed on the fender section of the car body to clearly indicate the width of the vehicle in front of the car body, and also to detect the presence of detected lamps such as head lamps and clearance lamps. This invention relates to a lighting circuit disconnection detection fender marker that detects and notifies a lighting state.

[Conventional technology]

Conventionally, in order to clearly indicate the width of the vehicle in front of the vehicle by lighting up the fender marker installed on the fender part of the car body at night, the fender marker has a built-in light emitting element such as a light emitting diode, and the light emitting element is attached to the driver's seat. A fender marker is used that is connected by wiring to a switch circuit provided on the side so that it can be turned on as desired.

However, this type of fender marker has a power circuit that is independent of the other lamps installed on the car, so it is only designed to clearly indicate the width of the vehicle in front of the car at night. Even if other lamps such as head lamps and clearance lamps are turned off due to breakage or the like, the fender marker remains lit.

[The problem that the idea aims to solve]

Generally, it is not possible to check the lighting status of headlights, clearance lamps, etc. from the driver's seat of a car, and there are problems such as having to get out of the car and check each time, especially in the case of a breakage accident while driving. It was extremely dangerous for vehicular traffic.

The present invention was devised in view of the above-mentioned problem, and is a lighting circuit disconnection detection system that can notify the failure of detected lamps such as head lamps and clearance lamps by switching and changing the lighting emission color of the fender marker. The purpose is to provide fender markers.

[Means to solve the problem]

In order to achieve the above object, the lighting circuit disconnection detection fender marker according to the present invention includes a disconnection detection circuit in the power supply circuit of the lamp that detects whether the lamp is lit or not, and uses a signal from the disconnection detection circuit to detect whether the lamp is lit or not. , the gist is to switch and change the lighting color of the fender marker.For example, change the lighted state to the lighted state, change the lighted state to the lighted state, and change the light emitted color. Detects and announces non-lighting of non-detection lamps.

Therefore, the lighting circuit disconnection detection fender marker according to the present invention has one or more light-emitting elements that switch to emit light in different colors inside a translucent machine case that is mounted on the fender body of an automobile. ,
A fender marker in which at least one light emitting element lights up in a predetermined color in conjunction with the ON/OFF of a lamp to be detected such as a headlamp or clearance lamp, and a switch circuit for the lamp to be detected which blinks when the switch is turned on or off. The main feature of the present invention is to include a core breakage detection circuit configured as shown in FIG.

Therefore, it is possible to change the normal lighting color of the fender marker to an abnormal lighting color based on the signal from the core breakage detection circuit, and to notify the user by changing the color of the fender marker to an abnormal lighting color. The lamp to be detected is equipped with two light emitting elements such as LEDs or bulbs that emit light of different colors, or a multicolor light emitting element that can light up and shine by switching between multiple different light emitting colors.
A breakage detection circuit consists of a fender marker that lights up one light emitting element or a predetermined color of a multicolor light emitting element in conjunction with ON and OFF, and a switch circuit of a detected lamp that blinks when the switch is turned ON and OFF. and a lighting switching circuit that converts the lighting side and non-lighting side of the light emitting element or switches the luminescent color to another different color based on the detection signal of the core breakage detection circuit.

[Effect]

According to the above configuration, when the detected lighting circuit, for example, the clearance lamp, is turned on, one of the pair of light emitting elements of the fender marker is turned on. When the clearance lamp is broken in this state and the switch circuit of the clearance lamp is opened, the lighting switching circuit is driven via the breakage detection circuit, and the lit side of the light-emitting elements of the fender marker is turned off, and the unlit side is turned on.

However, since the above two light-emitting elements emit different colors, when the light-emitting element is switched on by the above-mentioned lighting switching circuit, the emission color of the fender marker changes, and the clearance lamp is not lit. announce something. Therefore, specifically, for example, by configuring the light emitting element on the lighting side to be colored green during normal times and the light emitting element on the lighting side to be colored red when not lit, it is possible to alert the driver that the clearance lamp is in the non-lit state. At the same time, it keeps the fender marker lit to clearly indicate the width of the vehicle in front of the vehicle.

In addition, in the case where one light emitting element or a multicolor light emitting element is linked with a core breakage detection circuit, the core breakage of the lamp to be detected can be detected by turning off the light emitting element or changing the lighting of the multicolor light emitting element to another color. will be notified.

A lens member 3 made of a translucent material such as acrylic resin is provided in an opening 2b formed in a, thereby forming a hollow portion 4. The marker main body 2 has a bulging part 5a formed on the front side of a hollow rectangular tube-shaped insertion tube part 5 protruding from the lower surface, and a tongue-like elastic protrusion 5b bored on the rear side.
Due to the elastic return of the tongue-like elastic protrusion 5b, the vehicle body a
When the insertion tube part 5 is inserted into the mounting hole drilled in the fender part of the fender part, it is locked and fixed to the back surface of the fender part. Reference numeral 6 denotes a printed circuit board installed in the hollow part 4, in which two light emitting elements 7 and 8 made of LEDs are arranged at a position where the lens member 3 is desired, and other circuit elements are arranged. The light emitting elements 7 and 8 are selected to emit light of different colors, such as green and red.

The lighting switching circuit 12 consists of:

In the lighting circuit with the above configuration, when the switch S is turned on, a current flows to the lamp L through the resistor R1, and the lamp L is lit. At the same time, the transistor Tr1 connected to the green LED light emitting element L1 is turned on, so the green LED light emitting element L1 is lit. do. At this time, the transistor Tr2 to which the red LED light emitting element L2 is connected maintains an OFF state because a base voltage is applied by the collector current of the transistor Tr1, and the red LED light emitting element L2 is in a non-lighting state. Therefore, the fender marker 1 shines green.

Here, when the lamp L is disconnected, the base voltage of the transistor Tr1 increases and turns off, so the green LED light emitting element L1 is turned off and the red light emitting element L1 is turned off.
Transistor Tr2 connected to LED light emitting element L2
Since the base voltage is eliminated, it is converted to ON, and the red LED light emitting element L2 is turned on to change the luminescent color of the fender marker 1 to red.

That is, as shown in FIG. 3, if the lighting circuit disconnection detection fender marker is installed in the lighting circuit of the clearance light 9 of vehicle a, and the switch S is installed near the driver's seat, it is possible to turn on the clearance light 9. When the switch S is turned on, the green LED light emitting element L1 of the fender marker 1 lights up and shines green, and the clearance light 9

The resistor R1 is used as the disconnection detection circuit 11.
The light emitting element L1 is driven to light up by the potential difference generated between both ends of the light emitting element L1. The light emitting element L1 is connected in series with a resistor R2 of a predetermined capacity, and is connected in parallel with the resistor R1 to form a lighting circuit 10, and the polarity of the light emitting element L1 is parallel to that of the LED. A diode D1 is provided to form a surge current bypass circuit to prevent the LED from being destroyed.

The lighting circuit 10 having the above configuration turns on the switch S.
Then, the detected lamp L is turned on via the resistor R1, and the light emitting element L1 is turned on due to the potential difference generated between the two poles due to the current flowing through the resistor R1. Therefore, when the current in the resistor R1 decreases due to disconnection of the lamp L to be detected, the light emitting element L1
The voltage applied to the lamp becomes zero, the lamp goes out, and the non-lighting of the detected lamp L is notified.

Furthermore, FIG. 5 shows a third embodiment of the present invention, in which when a break in the lamp L to be detected is detected, a part of the light emitting element provided in the fender marker 1 is turned off to notify a break in the lighting circuit. It is.

Also, one more light emitting element L2 is configured in parallel with the lamp L to be detected, and two light emitting elements L1, L
2 is configured to project light from two windows arranged in the fender marker 1.

Therefore, when switch S is turned on, detection lamp L lights up and at the same time fender marker 1
The light emitting element L2 also lights up, and the relay switch Rs is also turned on by the relay Rc, and the light emitting element L2 turns on.

The light emitting element L1 is turned off to set it to the OFF state, and it is reported that the lamp L to be detected is not lit. However, the one light emitting element L2 remains lit and ensures the vehicle width display function of the fender marker 1.

In each of the above embodiments, one multicolor light emitting element is used instead of the two light emitting elements 7 and 8 emitting light of different colors, and the light emitting color is different depending on the output difference of the core breakage detection circuit 11, for example, red. Alternatively, it is possible to display the detection of a core break by lighting it up in green.
