The system for implementing a two-dimensional image of the LED lighting image according to an embodiment of the present invention configured as described above is to set and implement in advance the LED lighting image of the LED lighting means mounted on the object by a two-dimensional simulation through a computer, 3 Several effects can be obtained that can be expressed in dimensions.

Hereinafter, by using a program for implementing a two-dimensional image of the LED lighting image in a system to which the method for implementing the two-dimensional image of the LED lighting image according to the present invention having such a configuration, the LED lighting image on the object such as a bridge A method of simulating a two-dimensional image implementation of an image, and applying an LED illumination image to be implemented as a two-dimensional image to a target object will be described with reference to FIGS. 2 to 7.

First, when a user executes a program for implementing a 2D image of the LED lighting image by using the computer 100 in which the program for implementing the 2D image of the LED lighting image is stored according to an embodiment of the present invention, FIG. A screen window as shown is displayed on the monitor (S201).

Here, the program for realizing the image of the 2D LED illumination image may be, for example, a program based on a Microsoft foundation class (MFC) and a direct-x, which may be compatible in a window system environment.

The screen shown in FIG. 3 is displayed, but the displayed screen is open (1), run (2), loop run (3), modify (4), option (5). ) Items are displayed.

Open (1) item is to retrieve and display the image file of the object for implementing the two-dimensional LED illumination image, or information about the two-dimensional LED illumination image previously stored in the object set, for example shown in FIG. This function is used to load and display chart file information such as the following.

The operation (2) item is the LED illumination image stored in the image of the displayed object called up by the open (1) item and stored, for example, the sixth LED illumination image 6 to the eighth LED illumination image shown in FIG. This item executes the simulation of 8) once.

The loop operation (3) item is the LED lighting image stored in the image of the object displayed and displayed by the open (1) item, for example, the sixth LED lighting image (6) to the eighth LED lighting image shown in FIG. This item repeatedly executes the simulation in (8).

The change (4) item is an item that can stop execution of the loop operation (3) item and set and implement a plurality of LED light images in the object image, for example, the sixth LED light image 6 shown in FIG. A plurality of LED lighting images such as the eighth LED lighting image 8 may be set and implemented on a target object.

Specifically, the change (4) item is used to stop execution of the loop operation (3) item, and the right mouse button is pressed at an arbitrary position with respect to the object of the bridge shown in FIG. Any one of the LED lighting image, for example, the LED lighting image of ID number 7 of the plurality of LED lighting images, such as the sixth LED lighting image (6) to the eighth LED lighting image (8). 7) and its size and rotation angle can be specified.

The option (5) item is an item that can store or initialize information regarding the LED light image implemented as described above, or download various LED light images shown in FIG. 4.

In the state in which such items are displayed, a background image including an object such as a bridge is loaded and displayed on the screen through the open (1) item (S202).

That is, as shown in FIG. 3, the open (1) item is clicked to load an image file including an object such as a bridge and display the image file on the screen of the computer 100.

After loading a background image including an object such as a bridge shown in FIG. 3 and displaying it on the screen, a list of a plurality of illumination images to be set on a background image including an object such as a bridge through a change (4) item, that is, shown in FIG. The list of the illuminated image is loaded (S203).

Here, the lighting image list shown in FIG. 4 is a lighting image list corresponding to each ID number, for example, a columnar light source corresponding to the image 6 of the circular light source corresponding to the ID number 6 and the ID number 7. It is possible to load and display a list of multiple illumination images, including images 7 of. Many of these lighting images can be changed from existing lighting images or user-modified (4) items to newly stored text images, numeric images, sign-shaped lighting images, reflected light images on the water, and smog. Laser light may be an image or the like.

In addition, the illumination image list shown in FIG. 4 may include a moving image that is stored by the user and can be simulated by the LEDs provided in the plurality of LED luminaires 300.

After loading and displaying a list of illumination images, a desired illumination image is displayed on a background image including an object such as a bridge shown in FIG.

For example, the image 7 of the columnar light source corresponding to the ID number 7 in the list of FIG. 4 is assigned to the pillars of the bridge shown in FIG. 3 using a mouse, for example, and the size is set. Each of the images 7 can be resized to fit the image size of the bridge column. Of course, in addition to the image 7 of the columnar light source corresponding to the ID number 7, the image 6 of the circular light source corresponding to the ID number 6 may be set as a street lamp image.

In this case, a reflective lighting effect or a smog effect reflected in the river may be additionally set for the set image.

Alternatively, the moving image image stored by the user in the list of FIG. 4 may be positioned by using a mouse and an area may be set.

After setting and setting the lighting image to the background image including the object, the lighting direction is set for each of the lighting images set as described above (S205).

Specifically, in order to set respective color renditions for the image 6 of the circular light source and the image 7 of the columnar light source corresponding to ID No. 6 set by assigning each to the pillar of the bridge shown in FIG. 3, As shown in FIG. 5, the red (R), green (G), and blue colors of the button items (53-1) corresponding to the respective images (6, 7) set after the display screen (53) for color rendering are called up. Set the colors of red (R), green (G) and blue (B) using the color button 53-2 that designates (B), and red (R), green (G), and blue (B). The degree of dimming may be set using the dimming bar 53-3 for each of the images 6 and 7 that set the color of.

Accordingly, the rendering of the 2D background image and the illumination image can be easily performed by selecting the type of the illumination image set for the background image and specifying information such as the type, size, and rotation of the illumination light by using a mouse. .

After setting the color rendering for each lighting image, the preview is performed by simulation according to the color rendering of the set lighting image for the background image of the target object including the set lighting image (S206).

Here, the method of processing the illumination image for the lighting effect in performing the preview is as follows. In the case of the lighting production, the lighting is gradually brightened or darkened, that is, the dimming effect of the lighting light being turned on or off smoothly. The brightness is gradually displayed with the difference.

For example, as shown in FIG. 6A, the central "C" portion of the circular illumination image is colored according to an action program written by the user, and the brightness gradually decreases as the distance to the edge increases. The edges have no color and brightness, making the background look natural.

Or, it gives the light of the deepest chromaticity set in the center and realizes the illumination image that becomes thinner to the edge. When the generated lighting image is implemented on the background image, the edge portion is transparent and the color is mapped to the center portion with a gradual difference in chromaticity, so that the light naturally fades toward the edge.

In addition to the above-described simple form of illumination image, the actual light is produced by varying the influence range of the light according to the illumination of the surrounding situation.

According to the illuminance of the surrounding environment, two methods are used to express the directing of the lighting image. The first method is to reduce and enlarge the light image itself according to the ambient light. The second method is to set the transparency of the light image itself according to the ambient light.

Specifically, the first method may be implemented by reducing an illumination image for a background image having a high peripheral illumination and enlarging the illumination image for a background image having a low peripheral illumination. In addition, the second method may implement an effect that disappears by treating the illumination image with high transparency for the background image having high ambient illumination.

It is desirable to use these methods together to express the rendering of the illumination image according to the illumination of the surrounding situation.

The production of an illumination image using these methods together will be described with reference to FIGS. 6B and 6C.

First, the rendering of the lighting image is to set the color of the red (R), green (G), blue (B) for the light image using the color button 53-2, red (R), green (G) , The influence range is set based on the maximum value of chromaticity among blue (B).

For example, suppose you load a circular light image with a radius of 255 cm that fades from the center outwards. If the red (R), green (G), and blue (B) values are 0,0,0, respectively, The lighting image is not visible.

At this time, the transparency is maximized, even though the lighting gradually drawn, the portion drawn at the maximum brightness is also transparent and removed.

On the other hand, when the red (R), green (G), and blue (B) values are 127, 0, 0, respectively, as shown in FIG. 6B, red (R) having a maximum chromaticity of 255 is 127. It is implemented by affecting the middle of the lighting image.

Accordingly, in the case of the edge of "E" whose chromaticity is 127 or less, the background appears due to transparency, and the center portion of "F" also decreases the brightness by the transparency setting proportionally, as if the same shape was reduced. It is produced by a small light image. At this time, the setting of the transparency is applied proportionally according to the brightness.

Next, as shown in FIG. 6C, when the red (R), green (G), and blue (B) values are 255, 127, 0, respectively, the red (R) has a maximum chromaticity of 255, so that the mixed color is illuminated. It is implemented by affecting the whole image. Only the blend color is applied as is in the shape of the illuminated image with transparency set to zero.

In conclusion, it can be seen that the illumination image is proportionally reduced by the chromaticity of the light having the maximum value among the components of the illumination image. The user loads a round light of 255 cm and the illumination image is reduced to 50% when one of red (R), green (G), and blue (B) is the maximum chromaticity of 127.

In addition, the same effect as the reduction and magnification is achieved by setting the transparency in inverse proportion to the brightness in the entire illumination image as well as creating the influence range of the illumination due to the reduction and implementation of the image.

The following describes the implementation of the illumination image according to the change in the size of the brightness set in the illumination image.

In the simulation of the 2D image, simply rendering the 2D light image on the background image may cause error production depending on the surroundings. For example, a problem may occur in which the illumination image 7 ′, which is to be directed only to a portion of the strut of the bridge shown in FIG. 7, affects the surrounding background such as a back mountain far away on the same plane due to the constraint of the plane image.

To solve this problem, the lighting image itself is generated and loaded into the background image including the background so that the rendering effect is expressed in the background image.

That is, as shown in FIG. 8, as the leaves around the illumination are indirectly illuminated by the illumination image 70, as shown in FIG. 8, the state of the leaves may be generated as an image and placed in the background image. .

In the present invention, the brightness of the leaf indirect lighting is generated at a level lower than that of the main lighting. In addition, in the generation of the main lighting, the brightness is lowered toward the edge of the background image of "B" in the peripheral region of the illumination image of "A" according to the influence range. The generation of lighting images using these brightness differences makes it easy to simulate the actual motion of lighting like 3D.

After performing the preview by the simulation according to the lighting output using such methods, the computer 100 determines whether to determine the lighting output information according to the preview performed according to the user's command (S207). .

In this case, if the lighting output information according to the preview is not determined according to the user's command, the computer 100 returns to step S203 of loading the lighting image list to reset the plurality of lighting images in the background image.

On the other hand, if the lighting output information according to the preview is determined according to the user's command, the computer 100 transmits the determined lighting output information to the LED controller 200 and stores it in the storage unit at step S208.

After receiving the determined lighting output information from the computer 100, the LED controller 200 converts and transmits a signal suitable for the LED module 310 connected to the LED lighting means 300 corresponding to each of the plurality of lighting images. have.

Accordingly, the LED controller 200 sets the determined illumination output information as the direction information for the plurality of LED lighting means 300 and operates the plurality of LED lighting means 300 (S209).

The method for image realization of a two-dimensional LED lighting image according to the present invention can easily produce a variety of lighting images having a complex shape, such as a letter-shaped lighting that has not been produced in the conventional 3D modeling on the background image of 2D.

In particular, the method for realizing the image of the two-dimensional LED lighting image according to the present invention overcomes the limitations of the simulation method on the 2D image, including a sign-shaped lighting of the letter, reflection light reflected on the water, laser light on the smog, background image By using various lighting images such as lighting images as objects and loading them on the background image, a wide variety of effects can be simulated.

In addition, the method for realizing the image of the two-dimensional LED lighting image according to the present invention is to simulate the method to be installed in the computer or to confirm after installation in order to implement the production according to the user's requirements before the LED lighting installation Suggest. For this simulation, the conventional 3D modeling and lighting rendering techniques, which require complicated and specialized knowledge, are excluded, and the application range can be remarkably generalized by using 2D plane images.

In addition, the method for realizing the image of the two-dimensional LED lighting image according to the present invention expresses the various effects that can be seen in three dimensions while realizing the two-dimensional lighting image on the background image, and the brightness and color influence range of the actual lighting, etc. By directing the same as the actual lighting, it has the effect of previewing the excellent performance of lighting while reducing costs.

Although the technical idea of the present invention has been specifically described according to the above preferred embodiments, it is to be noted that the above-described embodiments are intended to be illustrative and not restrictive.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention.
