The present invention provides an LED capable of emitting light on a conductive element of a planar heating element which is mounted on the rear of the rearview mirror glass to generate heat by application of electricity in order to effectively remove frost and rain water formed on the outside rearview mirror glass surface of the vehicle. By forming a PCB, the LED is made to emit light by electricity applied for heating the planar heating element during the heating operation of the planar heating element, so that the driver can identify whether the planar heating element is heated.

The technology that removes frost or water droplets that block the rear view by attaching a heating element that generates heat inside the vehicle's outside rearview mirror has been introduced into various functions so far.

The operation of the heating element is equipped with an ON / OFF switch inside the vehicle to enable the driver to control the ON / OFF as needed, or in a more advanced form by the signal output from the moisture sensor mounted on the rearview mirror surface, etc. The heat generation of the heating element has been developed to automatically operate.

However, the above-described various heating element types have a problem in that the driver cannot determine whether the heating element generates heat. Therefore, when the light emitting function indicating whether the heating element mounted inside the outside rearview mirror is generated, It has been found that the driver can easily check whether the heating operation is completed and completed the present invention.

The application of such a developmental form also solves the following problems.

In other words, if the driver wants to change lanes or turn left or right while driving, the driver rotates the vehicle while observing the rear view through the outside rearview mirror after driving the installed turn signal. Since some blind spots are invisible, there is a possibility that they may collide with other vehicles located behind the side if they are inadvertently injured. There is a case to be done.

Therefore, if the outside rearview mirror is provided with an indication function for informing the driver that the other vehicle is approaching too close to the child vehicle, or an indication function for informing the driver of the other vehicle in a more identifiable form to inform the driver of the other vehicle's lane change. The risk factor during operation can be sufficiently reduced.

Accordingly, the present invention is to solve the above problems, the present invention allows the driver to easily check whether the heating element of the heating element mounted inside the outside rearview mirror, while simplifying the structure of the display function An object of the present invention is to provide an exterior rearview mirror for a vehicle having a light emitting display function that enables replacement and mounting at low cost even in a vehicle equipped with a heating element having no function.

In addition, the present invention provides a vehicle outside rearview mirror having a light emitting function for notifying the driver of the lane change of the own vehicle in an easy-to-identify form or for indicating to the driver that another vehicle is approaching too close to the own vehicle. There is another purpose to provide.

This object is achieved by adding a light emitting display function to the planar invention structure of the outside rearview mirror which the applicant has previously devised.

That is, the present applicant has proposed a planar heating element which can reduce the manufacturing cost and reduce the temperature deviation by shortening the manufacturing process in connection with the heating element technology of the vehicle exterior rearview mirror in the past, and that is the Republic of Korea Patent Publication No. 2000-0028608 No. 10, May, 25, 2000, was registered as a patent (Registration No. 10-0411401) and is still maintained.

By directly mounting or applying the light emitting display element to the conductor of the planar heating element, the object of the present invention can be achieved with a simple structure and low cost.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The planar heating element 1 with reference to FIG. 1 is mounted inside the housing 6 of the outside rearview mirror attached to the side of the vehicle, as shown in FIGS. Therefore, if frost, rain water, dew, etc. form on the surface of the mirror 7, the electricity is conducted and is configured to generate heat.

In the planar heating element 1, a first conductive body 2 formed in a predetermined pattern is printed on the insulating sheet 8, and a layer of carbon paste 3 is coated thereon. The first conductor 2 has a pair of first electrode terminals 11 having positive (+) (-) poles for conducting electricity, and a PCB (4) to which the first LEDs 10 which emit light through electrical conduction are attached. ) Is connected.

Method for manufacturing the planar heating element 1 is, as described in the published document of the Patent Registration No. 10-0411401 proposed by the applicant,

An etching resistor is printed in a predetermined pattern on the first conductor 2 laminated on the insulating sheet 8, and an etchant is sprayed to corrode the first conductors other than the printed portion of the etching resistor, and an aqueous alkali solution or the like. After the etching resist and the etchant are washed, the process is performed by printing using the carbon paste 3 and connecting the first electrode terminal 11 to the first conductor 2 in parallel. The planar heating element 1 of the present invention can be easily manufactured by simply adding a step of connecting the PCB 4 with 10 to a predetermined portion of the first conductor 2.

When the planar heating element 1 manufactured by the above process is attached to the rear surface of the mirror 7 installed in the housing 6 of the outside rearview mirror as shown in FIGS. 2 and 3, frost or rain water may be applied to the surface of the mirror 7. When the rear view is difficult through the outside rearview mirror due to a back light, the first electrode terminal 11 may be controlled by the driver's switch or as an output signal by a moisture sensor (not shown) attached to the mirror 7 surface. Since electricity is applied through the first conductor 2 and electricity is conducted to the first conductor 2, the layer of carbon paste 3 generates heat and the first LED 10 emits light. Thus, the driver may determine whether the surface heating element 1 generates heat. You can check it with the naked eye.

4 is a conceptual diagram illustrating a circuit configuration of a planar heating element according to an exemplary embodiment of the present invention. In order to enable the first LED 10 to emit light, the first conductor 2, the carbon paste 3, and the first conductor 10 may emit light. 1 briefly illustrates the configuration of the connection terminal 5 and the first LED 10 connecting the conductors 2 and the PCB 4, and are shown in FIGS. 5 and 6 according to the concept diagram of FIG. 4. Other embodiments of the invention disclosed will be described.

On the other hand, since the first LED 10 is configured to emit light using electricity for generating heat of the carbon paste 3 by being connected to the first conductor 2 of the commercially available planar heating element 1, Even a vehicle equipped with a conventional planar heating element can be easily replaced and replaced without addition of other electrical components just by replacing the planar heating element 1 of the present invention.

5 is a conceptual diagram illustrating a circuit configuration of a planar heating element according to another embodiment of the present invention. In addition to the circuit configuration of the planar heating element 1 described above, a second electrode terminal 21 is installed and the second electrode terminal 21 is installed. The second LED 22 is connected to the second conductor 22 and electrically connected to the second conductor 22 to emit light.

As illustrated, the second LED 20 is provided separately from the first LED 10, and the second conductor 22 and the second electrode terminals 21 for emitting the second LED 20 are firstly formed. The circuit is configured so as not to interfere with the conductor 2 and the first electrode terminals 11 so as to emit light regardless of the heat generation operation of the carbon paste 3.

The light emitting display function of the second LED 20 causes the driver to blink at the same time as a direction indicator (not shown) normally mounted on the vehicle when the direction indicator for changing lanes is operated. Can be used as a direction indicator to predict lane changes.

In addition, the second LED 20 emits light by an output signal of the object detection sensor when an object detection sensor (not shown) mounted on the outside of the vehicle detects another vehicle approaching the dangerous side of the vehicle. As a result, the driver can be used as an approach alarm display function for notifying the driver that another vehicle is approaching the vehicle, in which case the driver can appropriately drive defensive driving.

6 is a conceptual diagram illustrating a circuit configuration of a planar heating element according to still another embodiment of the present invention. In addition to the circuit of the first conductor 2 of a commercially available heating element having no light emitting display function on the planar heating element, a third electrode terminal ( 31) and a third conductor 32 connected to the third electrode terminal 31 and a third LED 30 electrically connected to the third conductor and capable of emitting light.

The third LED 30 may also perform a light emitting display function separately from the first electrode terminal 11 and the first conductor 2 for heat generation of the carbon paste 3, and the third LED 30. As described above, may be used as a direction indicating function or may be used as an approach alarm function.

By installing a light emitting LED that displays heat generation function, direction indication function and approach alarm function of the heating element on the mirror surface of the car, it is possible to easily detect the state and danger level of the vehicle, so that it is possible to promote defensive driving or safe driving. Will be.

In addition, since only the surface heating element needs to be replaced even in a vehicle equipped with a heating element that does not have a useful light emitting display function as described above, replacement and mounting can be performed at a low cost, thereby allowing a driver to use it freely.
