Description

Technical Field [0001] The present invention relates to a light guiding plate module for a side light emitting type light guide plate,

In particular, the present invention relates to an apparatus and a method for manufacturing a pattern pattern of a side light emitting type light guiding plate. More particularly, the present invention relates to an apparatus and method for producing pattern patterns of a side light emitting type light guiding plate, The light guide plate is formed such that the embossed and engraved patterns are easily engraved on the light guide plate according to a desired image.

A variety of lighting fixtures are used to provide light at night or in dark rooms or to illuminate objects. Especially, the lighting lamp that uses the light emitting diode (light emitting diode) as the light source has a lower power consumption than the incandescent lamp or the fluorescent lamp and saves the energy. In addition to the conventional light sources, the solid type point light source is robust, has a long life, In terms of characteristics, it is advantageous in terms of maintenance and the like.

However, since the illumination light with a simple combination of light emitting diodes emits optically clear monochromatic light to cause uncomfortable glare and eye fatigue to the user, it can be used for indirect lighting for direct lighting or indoors It is important that an appropriate lens or light guide plate is coupled.

Recently, a distance between a light emitting diode and a light guide plate for diffusing light is appropriately maintained, so that light from a point light source generated from a light emitting diode is converted into light of a planar light source (a light source having a light- Flat-plate lighting fixtures have been developed and widely used in various forms.

In general, the flat panel luminaire is classified into so-called edge-lighting type and direct-lighting type depending on the manner in which the light emitting diode is disposed, and in particular, the side luminescent type is slim and tired due to the relatively thin thickness. It is popular as a required light source.

For example, Korean Patent Publication No. 10-1221196, Korean Patent Laid-Open Publication No. 10-2011-0035354, Korean Patent Laid-Open Publication No. 10-2011-0066014, Korean Patent Laid-open Publication No. 10-2011-0113701, Type flat panel luminaire has been proposed.

As shown in FIG. 1 of Korean Patent Registration No. 10-1047754, a conventional side illumination type backlight device has a structure in which a plurality of LEDs 10, which are light sources, are disposed on one side or both sides of a light guide plate 20 Although not shown, optical sheets such as a diffusion sheet and a prism sheet are disposed on the upper side of the light guide plate, and a reflective sheet is disposed on the lower side.

The light emitted from the point light source 10 emitted from the LED light source 10 is scattered and totally scattered in the light guide plate 20 to be converted into a planar light source and light of the planar light source is emitted to the upper side of the light guide plate 20, .

In addition, Korean Patent Registration No. 10-0814008 discloses a light guide plate processing apparatus using a laser. As shown in FIG. 1, the laser generating apparatus 100 is arranged such that a laser beam is emitted to the outside, And is movable in the X-axis direction.

The laser head 200 has a focus lens (not shown) therein and irradiates the laser beam emitted from the laser generator 100 to the back surface of the light guide plate P. [

The bracket 300 is configured to fixly support the laser head 200.

In this conventional light guide plate processing apparatus, since the laser head 200 is supported by the bracket 300, the optical path of the laser beam in the Z-axis direction, that is, the vertical direction is always kept constant.

However, the conventional side-emission type flat panel illumination device does not show the embossing and engraving work of the light guide plate through laser processing, and in particular, there is no device concept for verifying whether the embossing and engraving are made according to a desired image.

The LED illumination device using the light guide plate according to the present invention is a surface light source structure in which the LED 11 is incident on one side of the light guide plate 20 and spread and scattered over the entire area of the light guide plate 20, An LED assembly 10 mounted on the printed circuit board 12, a light guide plate 20 for converting the light emitted from the LED assembly 10 into planar light by being incident on the light guide plate 20, And a reflective sheet 30 attached to the back surface of the light guide plate 20 and reflecting the incident light.

The LED assembly 10 is mounted on the printed circuit board 12 having a length corresponding to one side length of the light guide plate 20 along the longitudinal direction. Here, the LED assembly 10 may include a mold layer (not shown) for protecting the LED 11 mounted on the printed circuit board 12, and the mold layer may be formed of acrylic or silicon .

The light guide plate 20 is made of a plastic material such as polymethylmethacrylate (PMMA) or polycarbonate (PC), which is one of acrylic transparent resin, which is one of transparent materials capable of transmitting light emitted from the LED 11, Injection molding in a flat form by the series. Such a light guide plate 20 is excellent in transparency, weatherability, and colorability, and induces light diffusion when light is transmitted.

The light guide plate 20 is installed such that the light emitted from the LED 11 is incident on one side of the light guide plate 20 as shown in the drawing. At this time, the light guide plate 20 is thermally expanded by the heat emitted from the LED 11 So that the light guide plate 20 and the LED 11 are spaced apart from each other by a predetermined distance.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light guide plate for displaying an image by scattering light incident from a side surface by an engraved engraved pattern on an upper surface.

The intaglio pattern struck by the light guide plate can be determined in shape or size according to the brightness of the image to be generated by scattering the light incident from the light source positioned on the side of the light guide plate, Length, and depth determined by the width, length, and depth of the engraved pattern, and at least one of the width, length, and depth of the engraved pattern tends to increase as the degree of accuracy increases.

The length of each engraved pattern tangled on the light guide plate may range from 10 to 500 μm. The width of each engraved pattern can range from 10 to 300 μm, and the depth of each engraved pattern can range from 10 to 150 μm based on the deepest depth in each engraved pattern. The width, length, and depth of the pattern have a tendency to be proportional to the machining time tapped by driving the laser on. In addition, the width, length, and depth of the pattern can be adjusted by controlling the focal length of the laser, the laser power, and the laser aperture. The shape of the laser pattern tilted on the light guide plate is tilted in a negative shape, and the pattern shape in the longitudinal direction is the shallowest portion and the deepest portion of the pattern, and the central portion of the pattern is deepest . The deeper the depth, the greater the amount of light that is scattered, and it is brightly recognized. The wider the area, the wider the range of scattered light. The longer the length, the larger the amount of scattered light. However, if the light exceeds a certain range, the amount of light scattered by one pattern is large, so that light can not reach the opposite side of the light guide plate. Machining changes the length of the pattern and adjusts the depth and width by adjusting the focal length and machining speed. The image of the bright part can be processed with a small number of deep and wide patterns to facilitate the workability and can be realized by using a plurality of short and deep patterns.

The worker computer 100 includes a worker computer 100 and a laser processing device 200. The worker computer 100 analyzes an image file to determine a pattern to be tapped on the light guide plate, and transmits determination information to the laser processing device.

Then, the laser processing apparatus 200 processes the light guide plate according to the data transmitted from the worker computer to generate a light guide plate patterned in a predetermined pattern.

In addition, the present invention further includes a camera device 300 to photograph the processed light guide plate. When the photographing information is transmitted to the worker computer, the controller 400 compares the photographing information with the image information, And if it is determined that it is not normally performed, an alarm signal is outputted through the automatic alarm signal output unit 1000.

It can be broken down according to the work order as follows.

(A) storing images to be expressed by the operator computer 100 in a memory and defining brightness for each pixel; (b) determining the width, length, and depth of the engraved pattern to be stitched on the light guide plate according to the prescribed brightness using the worker computer 100; (c) depressing the engraved pattern on the light guide plate with the laser processing device 200 according to the width, length, and depth of the engraved pattern determined by the worker computer 100; (d) photographing the engraved pattern with the camera (300) and checking whether the original image is stored in the control unit (400) of the computer; (e) outputting an alarm signal through the alarm signal automatic output unit 1000 under the control of the control unit 400 when the result of the photographing by the camera 300 does not match the result of the inspection of the memory initial image.

In the step (a), the image to be expressed is stored in a memory of a computer and the brightness of each pixel is defined. For example, the original image file is subjected to a brightness correction operation using graphic editing software such as Photoshop Brightness can be defined for each pixel.

The step (b) may include the step of determining the width, length and depth of the engraved pattern to be drawn on the light guide plate according to the lightness defined in step (a), wherein the engraved pattern has a width, a length and a depth Can be determined. Also, the brightness may be proportional to the density of the pattern. The density of a pattern is the product of the width and the number of the pattern within a certain range. The width of the pattern is a * b * π when the length and width are assumed to be a and b, respectively, assuming that the shape of the pattern to be processed is an ellipse. The density of the pattern can be N * a * b * In this case, N represents the number of patterns within a certain range.

The step (c) may include grinding the engraved pattern on the light guide plate according to the determined width, length, and depth of the engraved pattern, for example, using a laser. The laser moves on two axes perpendicular to the plane and drives the laser on / off when each pattern is struck. In particular, by engraving an engraved pattern having the width, length and depth as determined in step (b) Continuous processing is possible.

Further, in order to facilitate laser processing, it is possible to convert an image divided into pixel units into a larger unit image and then perform laser processing. For example, an image file such as jpg is converted into a CAD file After that, laser processing can be performed.

The light guide plate according to the present invention is excellent in workability and can realize various images. The light guide plate is not limited to the material of the light guide plate, and the light guide plate may be made of polymethyl methacrylate, polycarbonate, polystyrene, styrene-methyl methacrylate copolymer Resin.

The light guide plate having the engraved pattern determined according to the brightness of the image can be utilized not only for various lighting applications having excellent visibility but also as a means for conveying visual information such as letters, photographs, logos, and symbols have.

If the spacing agent is not present, the body of the first self-holding means and the body of the second self-holding means are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, further spacers are provided so that the first magnetic holding means and the second magnetic holding means can be easily separated.

The reason why the spacing agent is provided only around the N pole of the second magnetic holding means is that the first magnetic holding means and the second magnetic holding means must be separated from each other when the relay switch is not operated, Pole and the S-pole of the second magnetic holding means are opposed to each other and the separated state can be easily maintained. If the spacing agent is wrapped to the S-pole of the second magnetic holding means, the strength of the S-poles of the first magnetic holding means and the second magnetic holding means is weakened by the interference of the spacers when the third relay switch is not operated The maintenance of the separation state may become unstable.

Accordingly, in the present invention, the spacers are provided only on the N pole of the second magnetic holding means to facilitate the separation of the first magnetic holding means and the second magnetic holding means, and when magnetic coupling is performed, So that the magnetically coupled state can be easily maintained. In practice, when the first magnetic holding means and the second magnetic holding means are coupled to each other, the N pole of the first magnetic holding means and the S pole of the second magnetic holding means come close to each other and are strongly magnetically coupled Even if the relay switch is turned off, the falling state of the circuit breaker 1131 is maintained, so that the ON state of the first circuit connecting switch sw1 can be maintained.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connecting an alarm signal output control unit to the power supply. When the user operates the automatic operation switch 1135 to stop the operation of the alarm signal in a state that the alarm signal output unit is turned off, The signal output control unit turns off the iron wire for power connection so that the operation of the alarm signal display unit is stopped so that the alarm signal is no longer outputted.

Hereinafter, the operation of the alarm signal automatic output unit 1000 will be described.

First, a control relation for outputting an alarm signal will be described. In the control unit, the controller applies power to the second relay switch to operate the third relay switch. Accordingly, the first circuit connection switch sw1 and the alarm signal output power switch sw2 are turned on by the operation of the third relay switch, and the alarm signal output control unit 1140 is powered on and the alarm signal is displayed.

When the first circuit connection switch (sw1) is activated, the control unit interrupts the operation of the second relay switch to cut off the operation of the third relay switch, and simultaneously operates the first relay switch.

On the other hand, if the operator turns off the first circuit connecting switch and the alarm signal output power switch in the middle of the output of the alarm signal, the control unit recognizes the first circuit connecting switch and the alarm signal output power switch. Then, the second relay switch is operated to operate the third relay switch, The alarm signal display unit 1150 can be operated continuously by returning the power to the alarm signal control unit 1140 while maintaining the closed circuit while moving the alarm signal display unit 1140.

That is, if the alarm factor is not solved, the present invention continuously outputs a warning sound to guide the user to solve the alarm factor.

In other words, if the control unit applies the switching signal to the second relay switch and the first relay switch, the power supply is returned again and the alarm signal is automatically output. Accordingly, even if the alarm signal is cut off It is possible to induce the operator to reliably solve the cause of the alarm signal.

If it is determined that the output of the alarm signal is no longer needed by the control unit, the power supply signal is no longer applied to the first relay switch and the second relay switch. In this case, the user manually operates the manual switch 1135 to turn off the alarm signal .

In addition, since the manager can not hear the alarm signal according to the ambient noise when the manager outputs the alarm signal, the noise measurement sensor 410 is installed in the computer to operate the malodor pumping means 420 By providing a malodor, it is possible to quickly identify the cause of the alarm and take measures.

In addition, the color pumping means 430 is electrically connected to the control unit 400 so as to visually recognize the alarm signal so that the red color is emitted, so that the server manager can grasp the alarm factor at a high speed.

12 is a diagram illustrating a pattern according to an exemplary embodiment of the present invention. Referring to FIG. 12, it is a general light guide pattern that a pattern is formed at a certain angle as shown in the figure. When the density of the pattern increases, scattering of light increases, If it is not formed, an engraved pattern is formed which is expressed in dark color while light is bypassed.

In addition, the present invention can be manufactured by forming a relief pattern around the relief pattern based on a relief pattern, or by embossing the relief pattern around the relief pattern.

Of course, the method of forming the relief pattern and the relief pattern at this time is as described above. In forming the relief pattern, the pattern is increased in density to increase the scattered light. In forming the relief pattern, Prevent spawning and induce it to look black.
