It consists of a PRND type dot ink light guide plate 200a and a disc shaped dot ink light guide plate 200b.

The PRND type dot ink light guide plate 200a is "

Figure 112010060428005-pat00002
"Embossed dots are formed on the surface in the vertical direction, and high brightness diffusion ink is printed on the embossed dots to spread the LED light emitted from the first single-type LED lamp in the horizontal direction when viewed from the top. To emit light of the embossed dot of the character shape.

This is the first single type LED lamp 200a-1, the "P" shaped dot ink portion 200a-2, the "R" shaped dot ink portion 200a-3, and the "N" shaped dot ink portion 200a-4. ), "D" shaped dot ink portion 200a-5, "+" shaped dot ink portion 200a-6, and "-" shaped dot ink portion 200a-7.

The PRND type dot ink light guide plate 200a according to the present invention is configured in the LED lamp for automatic transmission PRND.

The first single type LED lamp 200a-1 is formed of any one of a red LED, a green LED, and a blue LED to contact one side of the light guide plate body to emit light of one LED light. Do it.

The “P” dot ink unit 200a-2 is formed by silk printing a letter “P” on the surface of the light guide plate body, and embossing dots are blocked in a matrix shape on the silk printed “P” letter. The dot density of the "P" character embossed dots blocked in a matrix shape is denserly formed at a 5: 1 ratio than the "-" character embossed dots, and the thickness of the high brightness diffused ink printed on the "P" character embossed dots is "-". It is formed by printing at a 5: 1 ratio than character embossing dots.

This serves to receive the LED light through the embossed dot reflection of the "R" dot ink portion and high brightness diffusion ink.

Here, the dot density of the "P" character embossed dot is formed more densely than the "-" character embossed dot because the higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the "P" character embossed dot is "-". This is to form denser than character type embossing dot.

Then, the dot density of the "P" character embossing dot is denserly formed at a 5: 1 ratio than the "-" character embossing dot, and the 5: 1 ratio is from "-" character embossing dot to "P" character embossing dot. -"5" embossing dot, "+" embossing dot, "D" shaped embossing dot, "N" shaped embossing dot, "R" shaped dot Ink part must pass five embossing dots to 5 It is set to 1 ratio.

In addition, the thickness of the high brightness diffusion ink printed on the "P" character embossing dot is printed and formed at a 5: 1 ratio than the "-" character embossing dot. The thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. This is because the high brightness diffusion ink of the "P" character embossed dot is formed higher than the "-" character embossed dot.

Then, the thickness of the high-brightness diffusion ink printed on the "P" character embossing dot is printed at a 5: 1 ratio than the "-" character embossing dot, and the 5: 1 ratio is the "P" character embossing dot at the "-" character embossing dot High brightness diffusion ink of "-" letter embossing dot, High brightness diffusion ink of "+" shape embossing dot, High brightness diffusion ink of "D" shape embossing dot, High brightness diffusion ink of "N" shape embossing dot, "R" shape dot Since the high brightness diffused ink of the ink portion must pass a total of 5 high brightness diffused inks, the ratio is set at a 5: 1 ratio according to the ratio of the high brightness diffused inks.

The dot density ρ max may be calculated by the following Equation 1.

Figure 112010060428005-pat00003

As shown in FIG. 6, the distance of adjacent dot particles in the x-axis direction is set to Px (x-axis pitch), and the distance of adjacent dot particles in the y-axis direction is set to Py (y-axis pitch). Set the distance between neighboring dot particles to minD (minimum diameter), set the tilt angle toward the specific direction from the dot particle center axis to theta (θ), and set the radius of the dot particle to Rmax (maximum radius). ), The dot density ρ max is calculated as shown in Table 1 below.

Dot type Dot Particle 1 Dot Particle 2 Dot Particle 3 Px (x-axis pitch) 1,000 2.000 3.000 Py (y-axis pitch) 0.577 1.155 1.732 theta (θ) 30 ° 30 ° 30 ° minD (minimum diameter) 0.090 0.090 0.090 Rmax (maximum radius) 0.244 0.532 0.821 Dot density (ρ max ) 64.6 77.1 81.5

The " R " -shaped dot ink portion 200a-3 is located in the same line at the bottom of the " P " -shaped dot ink portion, and the letter " R " The embossed dot is formed by blocking the matrix shape, and the dot density of the "R" character embossed dot blocked by the matrix shape is denserly formed at a 4: 1 ratio than the "-" character embossed dot, and is formed on the "R" character embossed dot. The thickness of the high brightness diffused ink to be printed is formed by printing at a 4: 1 ratio than the "-" character embossed dot.

 It receives the light and diffuses it with the reflection to the "P" shaped dot ink part.

Here, the dot density of the "R" character embossed dot is formed more densely than the "-" character embossed dot because the higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the "R" character embossed dot is "-". This is to form denser than character type embossing dot.

In addition, the dot density of the "R" character embossing dot is denserly formed at a 4: 1 ratio than the "-" character embossing dot, so the 4: 1 ratio is from "-" character embossing dot to "R" character embossing dot. -"Charge embossing dot", "+" shape embossing dot, "D" shape embossing dot, "N" shape embossing dot have to pass four embossing dots, so it is set to 4: 1 ratio according to dot reflection ratio.

In addition, the reason why the thickness of the high brightness diffusion ink printed on the "R" character embossing dot is printed and formed at a 4: 1 ratio than the "-" character embossing dot is that the thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. This is because the diffusion of the high luminance diffusion ink of the "R" character embossed dot is higher than that of the "-" character embossed dot.

Then, in the case where the thickness of the high brightness diffusion ink printed on the "R" character embossing dot is printed at a 4: 1 ratio than the "-" character embossing dot, the 4: 1 ratio is the "R" character embossing dot at the "-" character embossing dot High brightness diffusion ink of "-" letter embossing dot, high brightness diffusion ink of "+" shape embossing dot, high brightness diffusion ink of "D" shape embossing dot, high brightness diffusion ink of "N" shape embossing dot, total 4 high brightness Since it must pass through the diffusion ink, the ratio is set to 4: 1 ratio according to the ratio of the high brightness diffusion ink.

The " N " -shaped dot ink portion 200a-4 is positioned at the bottom of the " R " -shaped dot ink portion so that the letter " N " is silk printed on the surface, and the embossed dot is printed on the " N " The dot density of the "N" character embossed dots formed into blocks in a matrix shape and densely formed in a matrix shape is denserly formed at a 3: 1 ratio than the "-" character embossed dots, and printed on the "N" character embossed dots. The thickness of the diffusion ink is formed by printing at a 3: 1 ratio than the "-" character embossed dots.

This receives the LED light through the embossed dot reflection and the high brightness diffusion ink of the "D" dot ink portion, and serves to diffuse and reflect the "R" shaped dot ink portion.

Here, the dot density of the "N" character embossed dot is formed more densely than the "-" character embossed dot because the higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the "N" character embossed dot is "-". This is to form denser than character type embossing dot.

The dot density of the " N " character embossed dot is denserly formed at a 3: 1 ratio than the "-" character embossed dot.

Figure 112010060428005-pat00004
"It consists of a shape, so the LED light must go through three embossing dots:"-"character embossing dot," + "shape embossing dot," D "shape embossing dot, will be.

In addition, the reason why the thickness of the high brightness diffusion ink printed on the "N" character embossing dot is printed and formed at a 3: 1 ratio than the "-" character embossing dot is that the thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. This is because the diffusion of the high brightness diffusion ink of the "N" character embossed dot is higher than that of the "-" character embossed dot.

Then, in the thickness of the high-intensity diffusion ink printed on the "N" character embossing dot is printed at a 3: 1 ratio than the "-" character embossing dot, the 3: 1 ratio is the "N" character embossing dot in the "-" character embossing dot High brightness diffusion ink of "-" character embossing dot, high brightness diffusion ink of "+" shape embossing dot, high brightness diffusion ink of "D" shape embossing dot, and the ratio of high brightness diffusion ink because total 3 high brightness diffusion ink must pass The ratio is set to 3: 1.

The " D " -shaped dot ink portion 200a-5 is located in the same line at the bottom of the " N " -shaped dot ink portion, and the letter " D " The embossed dots are formed by blocking the matrix shape, and the dot density of the "D" character embossed dots blocked by the matrix shape is denserly formed at a 2: 1 ratio than the "-" character embossed dots, and is formed on the "D" character embossed dots. The thickness of the high brightness diffused ink to be printed is formed by printing at a 2: 1 ratio than the "-" character embossed dot.

This receives the LED light through the embossed dot reflection of the "+" shaped dot ink portion and the high brightness diffusion ink, and serves to diffuse the reflection with the "N" shaped dot ink portion.

Here, the dot density of the "D" embossed dot is formed more densely than the "-" character embossed dot because the higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the "N" character embossed dot is "-". This is to form denser than character type embossing dot.

The dot density of the " D " shaped embossed dot is denserly formed at a 2: 1 ratio than the "-"

Figure 112010060428005-pat00005
It is set in a 2: 1 ratio according to the dot reflection ratio because the LED light has to go through two embossing dots up to a "-" character embossing dot and a "+" shape embossing dot.

In addition, the reason why the thickness of the high brightness diffusion ink printed on the "D" shaped embossing dot is printed and formed at a 2: 1 ratio than the "-" character embossing dot is that the thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. Therefore, the high brightness diffusion ink of the "D" shaped embossed dot is to be formed higher than the "-" character embossed dot.

Then, the thickness of the high brightness diffused ink printed on the "D" shaped embossing dot is printed at a 2: 1 ratio than the "-" character embossing dot, and the 2: 1 ratio is the "D" shaped embossing dot at the "-" character embossing dot. The high brightness diffusion ink of the "-" character embossing dot and the high brightness diffusion ink of the "+" shape embossing dot are set at a 2: 1 ratio according to the ratio of the high brightness diffusion ink because a total of two high brightness diffusion inks must pass.

The " + " shaped dot ink portion 200a-6 is located at the lower left side of the " D " shaped dot ink portion so that a letter composed of " + " Is formed by blocking the matrix shape, and the dot density of the "+" character embossing dot blocked into the matrix shape is densely formed at a ratio of 1.5: 1 than the "-" character embossing dot, and is printed on the "+" character embossing dot. The thickness of the high brightness diffused ink is formed by printing at a 1.5: 1 ratio than the "-" character embossed dots.

This receives the LED light through the embossed dot reflection of the "-" shaped dot ink portion and the high brightness diffusion ink, and serves to diffuse the reflection with the "D" shaped dot ink portion.

Here, the dot density of the "+" shaped embossed dot is formed more densely than the "-" character embossed dot because the higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the "+" shaped embossed dot is "-". This is to form denser than character type embossing dot.

In addition, the dot density of the "+" shaped embossing dot is denserly formed at a ratio of 1.5: 1 than the "-" character embossing dot, so that the 1.5: 1 ratio means that the light guide plate body is "

Figure 112010060428005-pat00006
"It's a shape, so the LED light is reflected directly from the"-"character embossed dot, so it's set to a 1.5: 1 ratio, depending on the dot reflection ratio.

In addition, the thickness of the high brightness diffusion ink printed on the "+" shaped embossing dot is printed and formed at a ratio of 1.5: 1 than the "-" character embossing dot. The thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. Therefore, the high brightness diffusion ink of the "+" embossed dot is formed to be higher than the "-" character embossed dot.

Then, the thickness of the high brightness diffusion ink printed on the "+" shaped embossing dot is printed at a 1.5: 1 ratio than the "-" character embossing dot, and the 1.5: 1 ratio is the "+" shaped embossing dot at the "-" character embossing dot. Since it diffuses directly past the high-brightness diffusion ink of the "-" character embossing dot, it is set at a 1.5: 1 ratio according to the ratio of the high-brightness diffusion ink.

The "-" -shaped dot ink portion 200a-7 is located in the same line at the bottom of the " + " -shaped dot ink portion so that the letters "-" The embossed dot is formed by blocking the matrix shape, and the dot density of the "-" character embossed dot blocked into the matrix shape is formed at 300 to 350 dpi, and the thickness of the high-brightness diffusion ink printed on the "-" character embossed dot is 10 µm. It is formed by printing at ˜100 μm.

It receives the LED light from the first single-type LED lamp, and serves to diffuse the LED light with reflection to the "+" shaped dot ink portion through the embossed dot reflection and high brightness diffusion ink.

The reason why the dot density of the "-" character embossed dot is formed at 300 to 350 dpi is lower than 300 dpi, so that the embossed dot density is lowered so that the reflection of the LED light received from the first single type LED lamp is low, and the LED up to the "P" character embossed dot is The reflection of the light is difficult, and when the dot density of the "-" character embossing dot is higher than 350dpi, the "-" character embossing dot density is increased so that the LED light reflection received from the first single type LED lamp is up to the "P" character embossing dot. Since the problem of darkening of the "P" character dot ink portion is not transmitted, it is preferable that the dot density of the "-" character embossing dot is formed at 300 to 350 dpi.

The reason why the thickness of the high brightness diffusion ink printed on the “-” character embossing dot is printed is 10 μm to 100 μm is formed when the high brightness diffusion ink is printed to 10 μm or less. It becomes low, and the spread of LED light is not transmitted to the "P" character embossing dot, so that the "P" character dot ink part becomes dark, and when it prints more than 100 micrometers, the high brightness printed on "P" character embossing dot occurs. Since the thickness of the diffusion ink is formed thick, a space is generated between the PRND type dot ink light guide plate and the upper case to be fastened, so that the LED light is not properly reflected to the upper case, and scattered and darkly expressed. It is preferable to print.

Next, the disk-shaped dot ink light guide plate 200b according to the present invention will be described.

The disk-shaped dot ink light guide plate 200b is formed in a disk shape, and embossed dots in the form of arcs are formed on the surface in the arc direction, and high-brightness diffusion ink is printed on the embossed dots to emit light from the second single-type LED lamp. When viewed from the top, the LED light is diffused from the center of the axis to the outward direction to play the role of emitting the embossed dot of the character shape.

It consists of the 2nd single type LED lamp 200b-1 and the disk type dot ink part 200b-2.

Disc-shaped dot ink light guide plate 200b according to the present invention is a vehicle instrument panel LED lamp, a garnish LED lamp, a vehicle interior mood light, CLEARANCE LAMP, TURN SIGNAL LAMP, BACK UP LAMP And brakes.

The second single-type LED lamp 200b-1 is made of any one of a red LED, a green LED, and a blue LED to be in contact with one side of the light guide plate body to serve to emit one LED light.

The disk character dot ink unit 200b-2 has a disk character on the surface of the disk, such as RPM, driving distance, driving speed, and fuel amount is silk-printed in a disk shape, and the embossed dot is matrix-shaped on the silk-printed disk character. The dot density of the outer-side embossed dots 200b-2b formed into blocks and formed into a matrix is denser than the central-axis embossed dots 200b-2a formed on the central axis at a 5: 1 ratio. The thickness of the high luminance diffused ink printed on the side embossed dots is printed and formed at a 5: 1 ratio than the central axis embossed dots.

This plays a role of diffusing the LED light formed in the central axis through the embossed dot reflection of the disk type dot ink portion and the high brightness diffusion ink in the outward direction from the central axis when viewed in plan view.

Here, the dot density of the outer embossed dot is denser than the central axis embossed dot formed on the central axis. The higher the dot density, the higher the reflection of the embossed dot is, so that the dot density of the outer embossed dot is the central axis embossing. This is to form more densely than dots.

The dot density of the outer embossed dot is denser at a 5: 1 ratio than the central axis embossed dot formed on the central axis. The ratio of 5: 1 is that the light guide plate is formed in a disk shape. Since it is reflected directly from the embossed dot, the ratio is set to 5: 1 according to the dot reflection ratio.

In addition, the reason why the thickness of the high brightness diffusion ink printed on the outer embossed dot is printed at a 5: 1 ratio than the central axis embossing dot is formed because the thicker the thickness of the high brightness diffusion ink is, the higher the diffusion of the high brightness diffusion ink is. The reason is that the diffusion of the high luminance diffusion ink of the side embossing dots is higher than that of the central axis embossing dots.

In addition, since the thickness of the high brightness diffusion ink printed on the outer embossed dot is printed at a 5: 1 ratio than the central axis embossed dot, the 5: 1 ratio is diffused directly from the central axis embossed dot to the outer embossed dot, so that the high brightness It is set at a 5: 1 ratio according to the ratio of the diffusion ink.
