8 to 11 are plan views illustrating a touch film according to various embodiments of the present disclosure, and FIG. 12 is a cross-sectional view illustrating a combination of an illumination lens, a touch film, and a back cover according to an embodiment of the present disclosure.

The touch film 500 is interposed between the back cover 300 and the illumination lens 400. In this case, the touch film 500 is a shape corresponding to the shape of the illumination lens 400, as shown in Figure 8, made of a transparent material that can transmit the light of the light source 610, touch film 500 ), The electrode pattern 510 is formed in a shape corresponding to the shape of the illumination lens 400.

In addition, one side of the electrode pattern 510 is provided with an electrode terminal 513 extending from one side of the touch film 500 and connected to the above-described knob substrate 233.

There is a capacitance between the electrode pattern 510 of the touch film 500 and the conductor around it, and since the human body is also a conductor, the capacitance of the touch film 500 when the user's body approaches the electrode pattern 510. This will change. At this time, the control unit 800 to be described later to detect the change in the capacitance to determine the operation signal and to control the operation of the light source 610.

According to another embodiment of the present invention, as shown in FIG. 9, an electrode pattern 510 including a ground (GND) pattern and a switch pattern 512 may be formed.

At this time, the outermost electrode pattern 510 is a ground (GND) pattern 511 for grounding, and the electrode pattern 510 is formed to be spaced apart from the inside of the ground pattern 511 to access or contact a human body. The switch pattern 512 is configured to sense, and the controller 800 controls the operation of the light source 610 according to the capacitance change of the switch pattern 512 compared to the capacitance of the ground pattern 511.

Here, the user may select the operation mode of the light source 610 according to the shape of the user's finger movement, that is, the touch motion, so that the electrode pattern 510 of the touch film 500 may be detected in parallel to detect the same. Or it may be arranged in various forms as needed, such as a lattice type, various operation modes of the light source 610 according to the touch motion will be described later.

The touch film 500 may be attached to the upper surface of the illumination lens 400 by an attachment means such as a double-sided adhesive tape so that the user's finger can easily detect the approach or contact of the user. It is of course also possible to be attached to the lower side of the cover 300.

As such, since the touch film 500 is attached to the rear surface of the illumination lens 400, that is, the image side surface, the vehicle lamp module 100 according to the exemplary embodiment of the present invention requires a separate switch panel installation space as in the prior art. Therefore, it is possible to increase the size of the illumination lens 400, thereby improving the design freedom.

At this time, in consideration of the degree of expansion and contraction of the touch film 500 according to the temperature change during long time use, it is preferable to leave a slight gap between the edge of the touch film 500 and the side wall of the illumination lens 400.

In addition, in order to prevent thermal deformation or separation of the touch film 500 and to improve sensitivity during long time use, the touch film 500 is preferably in close contact with the upper side of the illumination lens 400. The first coupling protrusion 331 and the second coupling protrusion 312 of the back cover 300 coupled to the illumination lens 400 interposed therebetween, while applying an elastic force in the direction of the illumination lens 400, the back cover 300. The lower side of the serves to support the pressure of the touch film 500.

Pressurized support can be provided.

However, as the touch film 500, the upper side of the illumination lens 400, and the lower side of the back cover closely adhere to each other, heat emitted from the light source 610 accumulates in the gap therebetween, and thus the touch film ( 500) may act as a factor in thermal deformation.

In order to prevent this, as in another embodiment of the present invention shown in FIG. 10, a plurality of pinholes 520 may be formed along the edge of the touch film 500.

In this case, as shown in FIG. 12, the pinholes 520 may communicate with the heat dissipation holes 311 of the back cover 300 described above, and thus the back cover 300, the illumination lens 400, and the touch. The heat accumulated in the gap between the films 500 may be radiated to the outside of the back cover 300.

As another embodiment, as shown in Figure 11, along the edge of the touch film 500, a metal pattern 514 of a material such as platinum or copper having a good thermal conductivity is formed by a coating or deposition method, for example For example, the metal pattern may be connected to a heat radiation fin (not shown) provided at one side of the back cover 300 by a conductive member such as a metal wire.

At this time, the heat accumulated in the touch film 500 is conducted to the heat radiation fin through the metal pattern 514 and then radiated.

On the other hand, such a heat dissipation structure may be provided in the illumination lens 400, as shown in Figure 7, when the illumination lens 400 and the back cover 300, the light source receiving portion 320 of the back cover 300 The heat dissipation hole 412 may be formed on one sidewall of the illumination lens 400 adjacent to the incision.

In addition, although not shown, the heat dissipation opening is formed on one side of the case 210 to dissipate heat inside the case 210 to the outside.

The lamp support part 600 is disposed above the back cover 300, and the lamp support part 600 is coupled to the coupling boss 222 of the cover 220 by a fastener such as a bolt.

In addition, the lamp support unit 600 is provided with a plurality of light sources 610 such as LED, the light source 610 so that the lamp support unit 600 can be accommodated in the light source accommodating part 320 of the back cover 300. Each of which is coupled to the inclined surface 620 protruding from one side of the, each of the light source 610 is coupled to the lamp substrate 630 for operation control. At this time, one side of the lamp substrate 630 is provided with a connector 631 for power supply and operation signal transmission.

The base part 700 is disposed above the lamp support part 600, and the base part 700 includes the coupling boss 222 of the cover 220 and the back cover boss 340 of the back cover 300, And it is coupled to the knob boss 232 of the knob button 230 through a fastener such as a bolt.

The control unit 800 including a PCB substrate is disposed on the upper side of the base portion 700, the control unit 800 is coupled through a fastener such as a coupling boss 222 and the bolt of the cover 220 described above, The knob button 230 and ON / OFF of the light source 610 and the operation mode control of the light source 610 are performed.

The controller 800 detects a change value of the capacitance received from each electrode pattern 510, determines a user's touch motion based on the detected value, and determines a touch motion corresponding to a preset motion. In this case, the operation control set in the corresponding motion is performed. The method of controlling ON / OFF operation, brightness and color adjustment of the light source 610 such as an LED by the controller 800 corresponds to a known technique, and thus a detailed description thereof will be omitted.

At this time, one side of the base portion 700 has a space therein and a wiring connection portion 710 having an opening in up, down, left and right directions is formed to protrude downward, and through this wiring connection portion 710, the knob substrate 233 and the controller ( 800 and the lamp substrate 630 are electrically connected by wiring (not shown).

14 and 15 illustrate various embodiments of electrode patterns that may be formed on the touch film.

As illustrated in FIG. 14, when the plurality of electrode patterns 510 are formed in parallel, a touch motion of a user moving in a direction (up and down in the drawing) crossing each electrode pattern 510 may be sensed. have.

In this case, an operation mode corresponding to each touch motion is previously input to the controller 800, and the controller 800 performs an operation mode corresponding to the detected touch motion.

16 is a flowchart illustrating a method for controlling a vehicle lamp module according to an embodiment of the present invention, and the vehicle lamp module may be controlled as follows.

First, when the user's finger is close to the illumination lens (S10), the THD level is detected and the detected value is compared with the preset THD level (S20).

At this time, when the detected value satisfies the proximity THD level and the detected value is maintained for a predetermined time and returns to the normal state, it is determined as the touch mode (S30) and the power source ON / OFF operation of the light source is started (S40).

Alternatively, when the detection value satisfies the proximity THD level and the detection value is maintained while the detection value is maintained for a predetermined time, it is determined as the motion mode (S50) and the operation of the light source corresponding to the motion such as brightness or color adjustment is performed. It starts (S60).

Looking at this in detail step by step as follows.

Detection step:

The touch film 500 senses a change in capacitance to sense the approach or contact of the illumination lens 400 of the user.

Judgment Steps:

It is determined whether the user's touch motion detected in the detection step matches the preset motion.

Here, the touch motion of the user is, for example, 'touch', 'up and down slide move', 'left and right slide move', 'diagonal slide move', 'circle slide move', 'right slide move', etc. This is possible.

In this case, the 'touch' may be determined by detecting that the capacitance is restored to a normal state after being maintained for a predetermined time in a changed state.

In addition, various types of 'slide movement' may be determined by detecting a change in coordinates in which a change in capacitance is detected while being maintained for a predetermined time with a change in capacitance.

Steps to follow:

As a result of the determination, when it matches the preset motion, the operation mode of the light source 610 according to the motion is performed.

For example, in the case of 'touch' motion, the light source 610 may be turned on and off by performing an ON / OFF mode, and in case of 'up and down slide movement' motion, the luminance of the light source 610 may be performed by performing a brightness control mode. In the case of the 'slide left and right movement' motion, the color of the light source 610 may be adjusted by performing the color adjustment mode.

In addition, in the case of 'diagonal slide movement', 'circumferential slide movement', and 'orthogonal slide movement', various types of light source 610 can be controlled as needed, and sunroof opening and closing, car audio operation, It is also possible to perform a separate device operation such as hands-free function of the mobile phone.
