Description

Half Mirror Image type Variable patterns Lamp and Vehicles Thereof}

The present invention relates to a hidden light lamp, and more particularly, to a vehicle to which a half-mirror image type variable pattern lamp is applied, which overcomes the limitations of first-generation aluminum (AL) deposition with NiCr deposition and depth-adjustable half mirror image.

In general, a hidden light of a vehicle has a characteristic of implementing a lamp image (ie, a lamp or lighting image) when a light source is turned on and converting to a deposition image (ie, an exterior design image) when not turned on.

For example, the hidden light is composed of a lamp housing, a lamp light source, and an AL deposition lens, and the AL deposition lens reflects external light while transmitting light from a light source inside the lamp through the AL deposition layer. In this case, the lamp light source uses a Light Emitting Diode (LED) (or Bulb), and the AL deposition layer is made of AL (Aluminum) material.

Therefore, in the hidden light, when the lamp is turned on, the external lens transmits light from the light source to realize a lamp image together with the lamp, while when the lamp is not turned on, the external lens reflects external light such as sunlight or light from an ambient light source, thereby depositing the hidden light. It can be converted into a deposition image using the visual texture of the layer.

In this way, the hidden light implements the vehicle lamp as a design element, thereby greatly contributing to improving vehicle marketability by increasing various and luxurious lamp images and sophisticated and advanced image effects in vehicles, especially electric vehicles.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying exemplary drawings, and since these embodiments can be implemented in various different forms by those skilled in the art as an example, the description herein It is not limited to the embodiment of

Referring to FIG. 1 , a vehicle 1 applies a variable pattern lamp 10 .

In particular, the variable pattern lamp 10 realizes an image differentiation concept by forming a lamp lighting image recognized from the outside as a half mirror image 10-1 in which the conventional AL deposition limitation is overcome by metal (eg, NiCr) deposition, , By combining the surface treatment pattern of laser cutting, the sense of depth is adjusted on the half mirror image (10-1), thereby realizing a new marketability effect with a low-cost communication lamp that is cost-saving compared to the existing communication type lamp.

Therefore, the variable pattern lamp 10 is characterized as a half mirror image type variable pattern lamp.

Furthermore, the variable pattern lamp 10 is formed by applying the half mirror module 20 to the front lamp 2-1 (ie, the headlight) or the rear lamp 2-2 (ie, the tail lamp) so that the front lamp 2 -1) or the rear lamp 2-2 is implemented as a variable pattern lamp 10. In this case, the front lamp 2-1 or the rear lamp 2-2 is a fog lamp, a turn signal lamp, a side repeater, an emergency light, a brake light ( Brake Lamp) and Back Up Lamp.

Specifically, the variable pattern lamp 10 includes a half mirror module 20, a lamp housing 30, a Garnish Vessel 60, and a leveling device 70, and is controlled by a lamp controller 90 do. In this case, the half mirror module 20 is combined with the lens bracket 40 and the reflector bracket 50 (see FIG. 2).

For example, the half mirror module 20 generates the half mirror image 10-1 as a lamp lighting image recognized from the outside. The lamp housing 30 is coupled to the rear portion of the half mirror module 20, and the variable pattern lamp 10 is connected to the front lamp 2-1 (ie, headlight) or the rear lamp 2-2 (ie, headlight). , tail lamp) is assembled using a body structure (eg, a front bumper part or a rear bumper part) to function as. The garnish bezel 60 has a black frame structure and is coupled to the front portion of the half mirror module 20 . The leveling device 70 controls the variable position distance A (see FIG. 4 ) together with the lighting angle of the half mirror module 20 .

In particular, the lamp housing 30 forms an inner space in which the half mirror module 20 is accommodated, and has a connector to which power lines and signal lines are connected to form an electric circuit with the lamp controller 90. The garnish bezel 60 has a structure that divides the lighting zone of the half mirror module 20 into multiple sections so that the half mirror module 20 has a shape exposed to the outside of the latest trend.

For example, the lamp controller 90 mutually communicates (eg, CAN (Controller Area Network)) with an ECU (Electronic Control Unit) 3 mounted in the vehicle 1, and vehicle information (a) of the ECU 3 ), signals such as vehicle speed, inter-vehicle distance, and object recognition are read and output as lamp control signals for the light source 21 (see FIG. 2) of the half mirror module 20 and the leveling device 70.

In particular, the ramp control signal is divided into a front communication mode (c) and a back communication mode (d) together with the auto level mode (b) of the leveling device 70 . In this case, the front communication mode (c) is divided into city, general, and highway modes (see FIG. 8), and the rear communication mode (c) is divided into warning, proximity, and safety modes (see FIG. 9).

Therefore, the lamp controller 90 operates as a central processing unit associated with a memory in which logic for checking vehicle information and outputting a lamp control signal is programmed and stored. In this case, the lamp controller 90 and the ECU 3 may be replaced with an engine controller that controls the engine of the vehicle 1 .

Meanwhile, FIGS. 2 and 3 illustrate detailed configurations of the variable pattern lamp 10 .

As shown, the lamp housing 30 is positioned toward the rear of the lamp and coupled to the rear portion of the half mirror module 20, and the garnish bezel 60 has a black color and is positioned toward the front of the lamp to form a half mirror module 20, and the leveling device 70 is coupled to the lamp housing 30 and leads from the rear side of the lamp to the half mirror module 20.

In addition, the half mirror module 20 and the garnish bezel 60 are coupled through the lens bracket 40 to maintain assembly robustness, and the half mirror module 20 and the lamp housing 30 are It is combined through the reflector bracket 50 to maintain the robustness of the assembly.

In particular, referring to FIG. 3 , the garnish bezel 60 covers the outer lens 27 of the half mirror module 20 and directs the light emitted from the outer lens 27 to the opening 60-1. By forming, the black color bezel portion other than the opening 60-1 covers the light. In this case, the lens bracket 40 also has an opening having the same shape as the opening 60-1 of the garnish bezel 60.

In addition, in the variable pattern lamp 10, the pattern lens 25 of the half mirror module 20 is a reflector ( 23) and the outer lens 27, the variable position distance (A) is changed, and the half mirror image 10-1 is maximized/intermediate/closed/minimum due to the change in interval due to the variable position variable distance (A). It changes to half mirror images 10-1a, 10-1b, 10-1c, and 10-1d (see FIG. 6). In this case, the leveling device 70 is described in detail with reference to FIGS. 5 to 7 .

Specifically, the half mirror module 20 is composed of a light source 21 and a reflector 23 forming a linear arrangement, a pattern lens 25 and an outer lens 27. In this case, in the linear arrangement, the outer lens 27 is positioned in the forward direction of the reflector 23 (ie, in front of the lamp) based on the reflector 23, and the outer lens 27 is positioned in front of the pattern lens 25. It is formed by being positioned in the direction (ie, in front of the lamp). Also, the light source 21 may be a surface light emitting source.

For example, the light source 21 forms a light irradiation path from above to below the lamp toward the reflector 23 in the inner space of the lamp housing 30 . In this case, the light source 21 is a light emitting diode (LED) or a LED chip, but a bulb may be used. Further, the light sources 21 are composed of a plurality of light sources arranged side by side at predetermined intervals, and the quantity depends on whether the variable pattern lamps 10 are used as the front lamps 2-1 or the rear lamps 2-2. It varies.

For example, the reflector 23 totally reflects the light from the light source 21 to form vertical light that goes down under the reflector, and then forms horizontal light perpendicular to the vertical light through multifocal reflection, and the horizontal light is patterned through a lens ( 25) to create a parallel light pattern (23-1).

Therefore, the reflector 23 is characterized as a multi-facet reflector (MFR) capable of irradiating beams at various angles to generate the parallel light patterns 10-1.

For example, the pattern lens 25 is made of a transparent PC (Polycarbonates) material (eg, Clear_PC), and divides both sides into a pattern surface 25a and a transmission surface 25b (see FIG. 3), and the transmission surface ( 25b), horizontal light among the parallel light patterns 10-1 reflected by the reflector 23 is incident, and the pattern surface 25a transmits the horizontal light toward the outer lens 27.

In particular, the pattern surface 25a is formed with a reflectance of about 85% by metal deposition (eg, AL deposition), and a surface treatment pattern is formed on the AL deposition portion by laser cutting after AL deposition. In this case, the reflectance of about 85% is a value applied as a reference value at which the horizontal light of the parallel light pattern 10-1 has straightness and can come out of the pattern lens 25.

For example, the outer lens 27 is made of a transparent PC (Polycarbonates) material (eg, Clear_PC) and divides both sides into an external recognition surface 27a and a deposition surface 27b (see FIG. 3), and the deposition surface In (27b), the half mirror pattern shape from the pattern surface 25a (see FIG. 3) of the pattern lens 25 is incident, and the external recognition surface 27a transmits through the half mirror pattern shape, and the lamp lighting image from the outside. It is created as a half mirror image 10-1 recognized as .

In particular, the deposition surface 27b is a NiCr black color matching the black color of the garnish bezel 60 by NiCr deposition, differentiated from the existing AL color, and a half mirror image (10-1) in which a sense of depth is formed in the half mirror pattern shape ) can be implemented.

Meanwhile, FIG. 4 illustrates a transparency optimization setting state of the half mirror module 20 using NiCr transmittance.

As shown, the half mirror module 20 has a difference in external visibility of the half mirror image 10-1 as a "VE (Virtual Environment) image" according to the transmittance of the deposition surface 27b of the outer lens 27. have

For example, the half mirror module 20 is "internally identifiable" even when about 50% transmittance is applied to the NiCr-applied deposition surface 27b of the outer lens 27 even in an unlit state (ie, the light source 21 is OFF). state, it forms a state of “internal fine discrimination possible” even when about 40% transmittance is applied, but forms a state of “internal discrimination not possible” when about 20% transmittance is applied.

In this way, NiCr deposition has a transmittance of less than about 10%, which makes it difficult to satisfy position light distribution regulations due to an excessively low transmittance, and a transmittance of about 30% or more makes it easy to observe the internal structure even when the lamp is not turned on, so internal parts must not be visible when the lamp is not turned on. The deterioration of the hidden light effect is experimentally proven.

Therefore, NiCr deposition on the deposition surface 27b of the outer lens 27 of the half mirror module 20 is set to a transmittance range of about 10 to 30%.

5 to 7, the half mirror module 20 adjusts the variable position distance A with the leveling device 70 so that the half mirror image 10-1 is changed into various half mirror images having different depths. exemplify the state of being

Referring to FIG. 5 , the half mirror module 20 forms a layout in which an outer lens 27, a pattern lens 25, and a reflector 23 are arranged in a straight line with respect to the observer 100.

From this, in terms of the layout of the half mirror module 20, the observer 100 and the outer lens 27 form an image visibility distance X, and the outer lens 27 and the pattern lens 25 forms a variable position distance A, and the pattern lens 25 and the reflector 23 form an image brightness distance Y.

In particular, the pattern lens 25 is moved in forward/rearward directions by the aiming moving rod 75 of the leveling device 70, so that the variable position distance A with respect to the outer lens 27 is changed and at the same time the reflector 23 The image brightness distance (Y) for ) is also changed.

To this end, the leveling device 70 is composed of an actuator 71, a gear 73, an aiming moving rod 75 and a moving bracket 77, and is located in the lower part of the lamp housing 30 to operate as a lamp controller. (90). In this case, the leveling device 70 is an electric auto leveling device.

For example, the actuator 71 is a motor equipped with a worm gear, forms an electric circuit with the lamp controller 90, and is driven by a signal of the auto level mode (b) to rotate forward or reverse. The gear 73 meshes with the worm gear of the motor (that is, the actuator 71) and rotates, increasing the torque with the gear ratio of the gear pair.

For example, the aiming moving rod 75 receives the output torque of the gear 73 and linearly moves forward/backward of the ramp, thereby forming a leveling distance B with a linear moving stroke. The movable bracket 77 is connected to or brought into contact with the pattern lens 25 of the half mirror module 20, so that the position change distance (A) between the pattern lens 25 and the pattern lens 25 within the leveling distance (B) of the aiming movable rod 75 ) to adjust.

In particular, the gear 73 is composed of a gear pair of gear A and gear B, and the gear ratio of gear A and gear B is set to 1.5:10.7. Due to this, the leveling device 70 moves 10.7 turns of gear B against 1.5 turns of gear A compared to the conventional 1: 1.5 gear ratio applied to gear A and gear B of gear 73, and the aiming movement rod ( 75) is formed by 10.7 times.

As a result, by matching the length of the aiming moving rod 75 to the gear ratio of 1.5:10.7, the leveling distance B is set to about 60 mm compared to about 5.6 mm in the conventional case. To this end, the lamp housing 30 is formed in a structure matching the rear housing space to a leveling distance B of about 60 mm to enable the package configuration of the leveling device 70.

Referring to the signal line (SIGNAL DIAGRAM) of FIG. 6, the signal line (SIGNAL DIAGRAM) is the voltage signal (SIGNAL VOLTAGE) of the actuator 71 versus the stroke (STROKE) of the aiming moving rod 75 (ie, the leveling distance As a relationship diagram for (B)), the range of the voltage signal SIGNAL VOLTAGE for the auto level mode (b) of the lamp controller 90 is illustrated.

Referring to the half mirror image 10-1 of FIG. 6, the half mirror image 10-1 has a leveling distance of about 60 mm (B) as the stroke of the aiming moving rod 75, and its depth is changed. becomes In this case, the position variable distance (A) is the maximum position variable distance (Aa), the upper position variable distance (Ab), the lower limit position variable distance (Ac) and the minimum position for a change of about 0 to 60 mm of the leveling distance (B). It is applied as a variable distance (Ad).

Specifically, the maximum position variable distance Aa is the maximum half mirror image 10-1a generating the half mirror image 10-1 with the maximum depth Da, and the upper position variable distance Ab is the half mirror image 10-1. The middle half mirror image 10-1b for generating the image 10-1 with an intermediate depth sense Db, and the lower limit position variable distance Ac is the half mirror image 10-1 with a close depth sense Dc The closest half mirror image 10-1c generated by , the minimum position variable distance Ad is the minimum half mirror image 10-1d that generates the half mirror image 10-1 with a minimum sense of depth Dd. implement

For example, the maximum sense of depth Da is set to about 10 mm, the middle sense of depth Db to about 6 mm, the proximity depth Dc to about 4 mm, and the minimum sense of depth Dd to about 2 mm. . Therefore, the sense of depth is changed to a discontinuous step, and the discontinuous step divides the variable position distance A into 4 sections, but if necessary, it can be applied by dividing into 3 sections excluding the middle sense of depth Db.

From this, the half mirror module 20 sets the initial state of the variable position distance (A) to 0 mm among the leveling distance (B) of about 60 mm of the leveling device 70, and the auto level mode (b) of the lamp controller 90 ), the half mirror image 10-1 is converted to the maximum half mirror image 10-1a <-> middle half It can be adjusted to the mirror image 10-1b <-> close half mirror image 10-1c <-> minimum half mirror image 10-1d. In this case, “<->” means mutual conversion state.

Referring to FIG. 7 , the leveling device 70 includes a plurality of first, second, and third leveling devices having different mounting positions with respect to the lamp housing 30 so that the lamp center of gravity W of the variable pattern lamp 10 is aligned. It consists of devices 70A, 70B and 70C.

For example, with respect to the center of gravity (W) of the lamp of the variable pattern lamp 10, the first leveling device 70A is positioned at the top left of the lamp housing 30, and the second leveling device 70B is positioned at the upper left corner of the lamp housing 30. The upper right position of the third leveling device 70C is arranged at the lower left position of the lamp housing 30, so that the center coordinates of the three-point leveling positions of the first, second, and third leveling devices 70A, 70B, and 70C are lamps. Corresponds to the center of gravity (W).

Therefore, each of the aiming moving rods 75 constituting the first, second, and third leveling devices 70A, 70B, and 70C forms a vertical plane with the moving bracket 77 connected to the pattern lens 25 and all have the same distance. In this layout characteristic, each of the aiming moving rods 75 is moved at the same time by the same distance, so that the forward/backward movement of the pattern lens 25 can accurately move by a distance that meets the leveling condition.

In this way, the variable pattern lamp 10 adjusts the variable position distance A with respect to the half mirror module 20 by the same movement of the first, second, and third leveling devices 70A, 70B, and 70C to form the pattern lens 25 ) can be implemented as a balanced movement.

Meanwhile, FIGS. 8 and 9 show a state in which the variable pattern lamp 10 is applied to the vehicle 1 and operated. In this case, the leveling device 70 is composed of the first, second, and third leveling devices 70A, 70B, and 70C, but driving under the control of the lamp controller 90 is described as the leveling device 70.

8 shows a case in which the variable pattern lamp 10 is applied to the front lamp 2-1 of the vehicle 1, and the front lamp 2-1 corresponds to the auto level mode (b) of the lamp controller 90. It operates in the same way as the variable pattern lamp 10 controlled in the forward communication mode (c).

First, the lamp controller 90 communicates with the ECU 3 to read the vehicle speed signal, inter-vehicle distance signal, object recognition signal, etc. of the currently running vehicle 1 as vehicle information (a), and among the vehicle information (a) Check the vehicle speed signal or vehicle speed signal and object recognition signal.

Subsequently, the lamp controller 90 selects the front communication mode (c) as one of city mode, general mode, and highway mode according to vehicle speed or vehicle speed and object recognition, and outputs auto level mode (b) according to the selected mode. do. In this case, the vehicle speed is classified into a low speed of 60 km/h or less for city mode, a medium speed in the range of 60 to 100 km/h for general mode, and a high speed of 100 km/h or more for highway mode.

As a result, the front lamp 2-1 is driven by the actuator 71 to move the position variable distance A of the pattern lens 25 according to the leveling distance B moved in the range of about 0 to 60 mm, so that the maximum / The half mirror image 10-1 is generated by setting one of the middle/close/minimum half mirror images 10-1a, 10-1b, 10-1c, and 10-1d as a selection mode.

For example, the city center mode generates the half mirror image 10-1 as the minimum half mirror image 10-1d with the minimum depth Dd, and the normal mode generates the half mirror image 10-1 as the normal mode. generates a close half mirror image 10-1c with a close depth Dc, and the highway mode converts the half mirror image 10-1 to a maximum half mirror image 10-1a with a maximum depth Da. create with

Therefore, the urban mode moves the filter lens 25 forward as much as possible (ie, toward the outer lens 27) when the vehicle speed is 60 km/h or less to match the city moving at a slower speed than usual, and moves the filter lens 25 to the minimum position relative to the outer lens 27. A 10 mm gap with a minimum sense of depth (Dd) is created at a variable distance (Ad), and the front lamp (2-1) illuminates the road ahead with a minimum half mirror image (10-1d).

As a result, the depth of the minimum half mirror image 10-1d is shallow in the front lighting of the vehicle 1 and the light is maximized, so that the oncoming vehicle or pedestrian can recognize the vehicle in motion and increase safety. .

On the other hand, the highway mode moves the filter lens 25 backward as much as possible (ie, in the direction toward the reflector 23) when the vehicle speed is 100 km/h or more to match the highway running at a very high speed, so that the maximum position variable distance with respect to the outer lens 27 A 60mm gap of maximum depth Da is created with (Aa), and the front lamp 2-1 illuminates the road ahead with a maximum half mirror image 10-1a. In this case, the maximum position variable distance Aa is the same as the position variable distance A, which is the initial set position of the filter lens 25.

As a result, the maximum half mirror image 10-1a takes the depth of light as deep as possible from the front lighting of the vehicle 1 and spreads the light, which is a problem caused by glare generated from oncoming vehicles during high-speed driving, that is, on the highway. Since the vehicle travels at a high speed, reducing the depth of the front lamp 2-1 and consolidating the light does not cause a dangerous situation due to glare to the driver of the oncoming vehicle.

In addition, the maximum half-mirror image 10-1a passes by quickly at once without being recognized by the other party if the light interval is small, but by using the characteristic that the time required to be recognized by the eye becomes longer when the light interval is small, even when driving fast, the light interval is wide. As a result, surrounding vehicles can easily recognize the driving pattern of the vehicle 1.

In addition, in the normal mode, the filter lens 25 is moved near and backward (ie, in the direction toward the reflector 23) when the vehicle speed is in the range of 60 to 100 km per hour according to the road running at normal driving speed, so that the lower limit position with respect to the outer lens 27 A 20mm gap of proximity depth Dc is created with the variable distance Ac, and the front lamp 2-1 illuminates the road ahead with the proximity half mirror image 10-1c. In this case, the 20mm gap of the lower limit position variable distance Ac is applied as a default value of the position variable distance A.

Therefore, the normal mode provides the most normal perception in a normal driving state of the vehicle 1 in the city mode and the highway mode.

9 shows a case in which the variable pattern lamp 10 is applied to the rear lamp 2-2 of the vehicle 1, and the rear lamp 2-2 corresponds to the auto level mode (b) of the lamp controller 90. It operates in the same way as the variable pattern lamp 10 controlled in the back communication mode (d).

First, the lamp controller 90 communicates with the ECU 3 to read the vehicle speed signal, inter-vehicle distance signal, object recognition signal, etc. of the currently running vehicle 1 as vehicle information (a), and among the vehicle information (a) Check the following distance signal.

Subsequently, the lamp controller 90 selects the rear communication mode (d) as one of warning mode, proximity mode, and safety mode according to the degree of the inter-vehicle distance, and outputs the auto level mode (b) according to the selected mode. In this case, the inter-vehicle distance is divided into a collision distance (S1) of 10 m or less for warning mode, a contact distance (S2) in the range of 10 to 50 m for proximity mode, and a non-collision distance (S3) of 50 m or more for safe mode, but these are narrower vehicle speeds. It can be further subdivided into sections and applied.

As a result, the rear lamp (2-2) is driven by the actuator 71 to move the position variable distance (A) of the pattern lens 25 according to the leveling distance (B) moved in the range of about 0 to 60 mm, so that the maximum / The half mirror image 10-1 is generated by setting one of the middle/close/minimum half mirror images 10-1a, 10-1b, 10-1c, and 10-1d as a selection mode.

For example, the warning mode generates the half mirror image 10-1 as the minimum half mirror image 10-1d with the minimum depth Dd, and the proximity mode converts the half mirror image 10-1 to the normal mode. generates a close half mirror image 10-1c with a close depth Dc, and the safe mode converts the half mirror image 10-1 to a maximum half mirror image 10-1a with a maximum depth Da. create with

Therefore, the warning mode moves the filter lens 25 forward as much as possible (ie, toward the outer lens 27) at an inter-vehicle distance of 10 m or less, where the risk of collision between the vehicle 1 and the rear vehicle 200 is high, so that the outer lens A gap of 10 mm with a minimum sense of depth (Dd) is created as a minimum position variable distance (Ad) for (27), and the rear lamp (2-1) creates a minimum half mirror image (10-1d) in the rear vehicle (200) recognize in

As a result, the minimum half mirror image 10-1d has a shallow depth in the rear lighting of the vehicle 1 and allows the light to be concentrated as much as possible, so that the distance between the front vehicle and the vehicle is close in the rear vehicle 20 with the narrowed half mirror image interval as much as possible. intuitively recognizable.

On the other hand, in the safety mode, the filter lens 25 is moved backward as much as possible (ie, toward the reflector 23) when there is no risk of collision between the vehicle 1 and the rear vehicle 200, and the outer lens ( 27) creates a gap of 60 mm with a maximum sense of depth (Da) with a maximum position change distance (Aa), and the rear lamp (2-2) illuminates the front road with a maximum half mirror image (10-1a).

As a result, the maximum half mirror image 10-1a takes the depth of light as deep as possible from the rear lighting of the vehicle 1 and spreads the light, so that the rear vehicle 20 has a maximum distance between the half mirror image and the front vehicle. It can be intuitively recognized that the distance is maintained at a relatively long safety distance.

And, in the proximity mode, there is no risk of collision between the own vehicle 1 and the rear vehicle 200, but the filter lens 25 is moved to the near rear (that is, in the direction toward the reflector 23) at an inter-vehicle distance of 10 to 50 m, which is a safety distance. ) to make a 20mm gap of close-up depth (Dc) as the lower limit position variable distance (Ac) for the outer lens 27, and the rear lamp 2-1 is a close-up half mirror image 10-1c. illuminates the road

As a result, the close half mirror image 10 - 1c collects light by taking a little deeper the sense of depth of light from the rear lighting of the vehicle 1, so that the rear vehicle 20 has a relatively narrow half-mirror image interval and distance from the front vehicle. You can intuitively recognize that is getting closer.

As described above, in the half-mirror image type variable pattern lamp 10 applied to the vehicle 1 according to the present embodiment, the collimated light 23-1 of the reflector 23 that totally reflects the light of the light source 21 is AL A half mirror module 20 formed as a laser pattern in the deposited pattern lens 25 and generating lamp illumination as a half mirror image 10-1 by passing through the NiCr deposited outer lens 27, and the pattern lens By including a leveling device 70 that moves the variable position distance A formed with the outer lens 27 in the forward/backward direction by changing the position of the outer lens 25, it is possible to achieve AL (Aluminum) deposition through NiCr deposition. By solving the limitations of 1st generation hidden lighting, it is possible to implement 2nd generation hidden lights that reflect consumer trends. In particular, by adjusting the depth of the half mirror image using NiCr deposition, the lamp implements a communication function, making it a vehicle product as a low-cost communication lamp. You can elevate your sanity.
