201241801 凊參考圖3 ’圖3為可程式光源控制器之驅動電路之示意 圖。光源21之每一發光區之LED皆由一個獨立LED驅動器 根據個別的控制訊號所驅動’例如’發光區A1到C5之LED DA1到DA5分別由LE：D驅動器GA1到GA5根據控制訊號 SA1到SA5所驅動。LED驅動器之定電流(c〇nstant current)為 LED額定電流iso的K倍，即驅動電流為k*IS0，LED驅動 器利用工作比(duty ratio)為1/K的脈衝寬度調變(PWM)控制訊 號來控制LED的發光，因此驅動電流的平均電流等於led的 額定電流。一般來說，印刷影像23中的正常區仍會保持一定 的冗度，所以突顯區之亮度必須高於正常區，也就是突顯區之 LED要產生更高的亮度，才能有足夠的對比。一般燈箱的亮 度約1500至2000 lux，如此突顯區的亮度需要6000至8〇〇〇 lux 才能達^四倍對比以上。由於LED具有高速反應速度，且LED 的發光το度與驅動電流大約成正比，例如，Led正常的驅動 電ml為20mA’若在短時間内將驅動電流提高到8〇mA，則led 的焭度也約為原來的4倍亮度。然而，當以大電流驅動LED 的時間太長時，大電流的熱效應將造成溫度上升，使得LED 的亮度將下降。另外，如果各發光區之LED皆可產生6〇〇〇至 8000 lux的亮度，所需的成本太高。因此，本發明之廣告燈箱 2>0利用_PWM控制訊號將突顯區的亮度調整為正常區的數倍 亮度，每一發光區只需產生1500至2〇〇〇 lux的亮度 減少整體材料費價格。 立請參考圖4及圖5,圖4為正常區之光源之控制訊號之示 忍圖，圖5為突顯區之光源之控制訊號之示意圖。在本實施例 中’ LED之PWM控制訊號之工作比設定為1/K，但是PWM 控制訊號之週期分為兩種，第一種週期Ts用於控制正常區之 ^ed，週期Ts可設定在16ms以内，第二種週期Td用於控制 突顯區之LED，週期Td可設定為1/4秒、2/4秒、3/4秒或1 201241801 秒，視突顯區之LED所需而有不同的值。由於人眼的視覺暫 留現象’當LED發光的閃爍頻率大於每秒3〇次以上時，人眼 無法察覺LED的閃爍’而是看見LED連續發亮，此時人眼所 見之亮度大小為LED閃爍發光的平均值。因此，當以相同的 驅動電流驅動LED時，藉由調整控制訊號之週期可控制LED 的亮度。如圖4所示，PWM控制訊號之週期Ts為16ms，工 作比為25%’則LED導通的時間為4ms，關閉的時間為l2ms， LED的閃爍頻率為每秒62次’此時人眼所看見的LED為連續 發亮，亮度大小約為最高亮度的25%。如圖5所示，以相同的 驅動電流驅動LED，但PWM控制訊號之週期Td為l〇〇〇ms， 工作比為25%，則LED導通的時間為250ms ’關閉的時間為 750ms ’ LED的閃爍頻率為每秒1次，此時人眼已無視覺暫留 現象，所看見的LED為明、暗、明、暗的閃爍發光，而亮度 大小為最高亮度。因此，在LED的驅動電流相同的情況下， 藉由調整控制訊號之週期，即可使廣告燈箱中突顯區的亮度呈 現正常區的4倍亮度。 請參考圖6，圖6為正常區之光源之控制訊號之時序圖。 一般電源供應器（Power Supply)除了規範額定功率(rati power)外，也規範了瞬間最大功率(transit maximum 常瞬間最大功率約為額定功率的135~15G%左右。假設圖3中 每一 LED驅動器之電流為80mA，LED電壓為4V，丘有】〇〇〇 顆LED ’當每-LED驅動H開啟之控制訊號都落在同一時 ^置時，對電源供應器而言，最大功率將為所有驅動器的功率 I和’則電源供應ϋ之額定功率必須設計為8QmAx 1000=3肩，然而實際上lED的平均消耗功率只有1/4 ，。因此，在本實施例中，將LED驅動器開啟之#制‘ 作時序安排’使正常區賴應之發光科會全部：時間門 啟，如此就可以使職低額定功率之魏供絲 寺= 不，以光源之正常區為例，第一列發光區 圖戶】 201241801

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an advertising light box, and more particularly to an advertising light box of an effect. In the J red-type dynamic [previous technology] advertising light box is mostly used for advertising or a small amount of living space, increase the variation of indoor dressing, but because the wide brush image is a fixed pattern or texture, can not be changed, on Often, monotonous, and less attractive to those who watched. The other 2 flat images are clearly visible during the day, but at night they lose their propaganda and wide brush. The advertising light box is equipped with a light source, and the light source is projected on the printing box. The light source is only used to illuminate the printed image. The pattern is wide and wide = , the change 'advertising effect is slightly unsatisfactory. This kind of advertising light box is fixed on the 5th. Signboards, live-turn advertising signs, roof ads, wall-mounted billboards, etc. Yin: Need ίίΐί: ΐ ΐ 日光 日光 ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ === IIV^ μι The purpose of ΐ is to replace 曰t currently with LED as the light source, the overall bright 咐. Therefore, the function of the coffee and [invention content] 201241801 supply and material reduction dynamic effect light box with green. The illumination of the advertisement Ci--#1 image includes a plurality of illumination zones within a plurality of illumination zones, and the control method comprises 11° according to the illumination zone of the printed image. Corresponding to the complex number of degrees of comparison; and the programmable light source controller generates different brightness according to the complex number of the plurality of signals. A kind of advertising light box for providing - the light source of the printed image, the comparison information of the plurality of pens, and the programmable light. The source is disposed behind the printed image, and the light source includes a plurality of colors. The comparison information is determined according to the content of the printed image. The information system corresponds to a brightness-to-program light source control 11 generated by the plurality of light-emitting areas, and is used to drive the plurality of brightness comparisons generated by the plurality of times. [Embodiment] Fig. 1 shows a light source 20 and a programmable light source controller 22 according to a first embodiment of the advertising light box of the present invention. After the print image 23 is placed, the programmable light source controller 22 uses the μ* light source 21 to provide illumination of the printed image 23. The user can edit the pair nf!* to control the brightness change of the light source 21 and then enter the comparison information into the programmable circuit =: controller 22. The light source 21 is an array of light-emitting diodes (LEDs), and each LED=light brightness can be side (four), so the advertising light box of the present invention can reach one, and the outside of the wide J light box: (1) can (4) open the arbitrary area Or off 1 = to the effect of the screen secret; (2) can be arbitrary area _ light source brightness, that is, save energy; (3) can improve the brightness contrast for the content of the printed image, to attract 201241801 to attract the attention of the viewer. Please refer to FIG. 2, which is a schematic diagram of the control system of the light source of the advertising light box. The light source 21 includes a plurality of light-emitting areas A1 to C5, and each of the contrast information is compared with the brightness of the light-emitting areas A1 to C5. In this way, the programmable source controller 22 can drive the light source according to the plurality of comparison information % to different brightness and touch. The duplicate record comparison information 24 is stored in the external record, and the second "external" 5 is a portable memory or a memory card. The programmable light can directly read the plurality of pen contrast information 24 from the external memory 25, and the pen pair 24 is copied and stored in the inner body of the programmable light source controller 22, and then the external clock 25 can be removed. Each of the light sources 21 emits two or less i, LEDs or a plurality of LEDs ’ which may be composed of white* LEDs or red, two and w-light LEDs. Each of the light-emitting areas can be independently controlled, and the source 22 can individually adjust the brightness and color order of each light-emitting area to 8 or 4 steps. In the present embodiment, the two S, the contents of the image 23, set the light-emitting area A1 to. 』 pen = and: 'two one map gas pair: information wide record ^ t ί P brush image 23 mainly contains the pattern P Bu]) 2, 'So the map (four), P2, P3 corresponding to the light area B4 Shibei The control of the dynamics from the bottom up can be controlled by three comparisons of information % t H ^ Μ to control the illumination area B4 to illuminate, and the remaining illuminations ^^^ control the illumination area B3 to illuminate, and the remaining hair is worn Factory comparison _ Bellow 24 system lighting, please light up, the rest of the hair first = bright m information control memory 25 re-" number after the 201241801 凊 reference to Figure 3 'Figure 3 is a schematic diagram of the drive circuit of the programmable light source controller. The LEDs of each of the illumination areas of 21 are driven by an independent LED driver according to individual control signals. For example, LEDs DA1 to DA5 of the illumination areas A1 to C5 are respectively controlled by LE:D drivers GA1 to GA5 according to control signals SA1 to SA5. The driving current of the LED driver (c〇nstant current) is K times the rated current iso of the LED, that is, the driving current is k*IS0, and the LED driver uses a pulse width modulation (PWM) with a duty ratio of 1/K (PWM). Control signal to control the LED's illumination, so the average current of the drive current is equal to the LED's rating In general, the normal area in the printed image 23 will still maintain a certain degree of redundancy, so the brightness of the highlighted area must be higher than the normal area, that is, the LED of the highlighted area should produce higher brightness to have sufficient contrast. The brightness of the general light box is about 1500 to 2000 lux, so the brightness of the highlighted area needs 6000 to 8 lux to reach four times the comparison. Because the LED has a high speed response speed, and the LED illuminance and drive current are about In proportion, for example, Led's normal drive power ml is 20 mA'. If the drive current is increased to 8 mA in a short time, the brightness of the LED is about 4 times that of the original. However, when driving the LED with a large current. When the time is too long, the thermal effect of high current will cause the temperature to rise, so that the brightness of the LED will decrease. In addition, if the LEDs of each light-emitting area can produce brightness of 6〇〇〇 to 8000 lux, the cost is too high. The advertising light box 2>0 of the present invention adjusts the brightness of the highlighted area to a multiple of the brightness of the normal area by using the _PWM control signal, and each light-emitting area only needs to generate a brightness reduction overall material of 1500 to 2 lux. Please refer to Figure 4 and Figure 5, Figure 4 is the control signal of the light source in the normal area, and Figure 5 is the schematic diagram of the control signal of the light source in the highlighted area. In this embodiment, the LED control signal of the LED The working ratio is set to 1/K, but the period of the PWM control signal is divided into two types. The first period Ts is used to control the normal area, the period Ts can be set within 16ms, and the second period Td is used for control. The LED of the highlighted area, the period Td can be set to 1/4 second, 2/4 second, 3/4 second or 1 201241801 seconds, which has different values depending on the LEDs required for the highlighted area. Due to the visual persistence phenomenon of the human eye, when the blinking frequency of the LED illumination is greater than 3 times per second, the human eye cannot detect the flashing of the LED, but the LED is continuously illuminated, and the brightness seen by the human eye is LED. The average of the flashing luminescence. Therefore, when the LED is driven with the same drive current, the brightness of the LED can be controlled by adjusting the period of the control signal. As shown in Figure 4, the period Ts of the PWM control signal is 16ms, the working ratio is 25%', the LED is turned on for 4ms, the off time is l2ms, and the LED blinking frequency is 62 times per second. The LEDs seen are continuously lit and the brightness is about 25% of the maximum brightness. As shown in Figure 5, the LED is driven with the same driving current, but the period Td of the PWM control signal is l〇〇〇ms, the working ratio is 25%, the LED is turned on for 250ms, and the off time is 750ms. The blinking frequency is 1 time per second. At this time, the human eye has no persistence of vision. The LEDs seen are bright, dark, bright and dark, and the brightness is the highest brightness. Therefore, in the case where the driving currents of the LEDs are the same, by adjusting the period of the control signal, the brightness of the highlighted area in the advertising light box can be rendered 4 times the brightness of the normal area. Please refer to FIG. 6. FIG. 6 is a timing diagram of the control signals of the light source in the normal zone. In addition to the standard rated power (Rati power), the general power supply also regulates the instantaneous maximum power (transit maximum instantaneous maximum power is about 135~15G% of the rated power. Assume that each LED driver in Figure 3 The current is 80mA, the LED voltage is 4V, the hill has a 〇〇〇 LED LED 'When the control signal for each LED drive H is on the same time, the maximum power will be all for the power supply. The power I of the driver and the power rating of the power supply must be designed to be 8QmAx 1000=3 shoulders. However, the average power consumption of the lED is only 1/4. Therefore, in this embodiment, the LED driver is turned on # The system's 'scheduled arrangement' makes all the lighting departments of the normal area rely on: the time gate, so that Wei Weisi Temple can be used for low rated power = no, taking the normal area of the light source as an example, the first column of light-emitting areas Figure 4: 201241801 The conduction clocks do not overlap each other, that is, the timing is arranged every four columns ,jit time, so the fifth column of the illuminating area and the first column send ^ ίίΐ her smoke, such as the silk source 21 supplement - only 1 /4 LED ^, the device The rated power only needs to be designed as 1/4 of the above example, about 80W. The total number of LEDs in the highlighted area is not much, and the impact on the power of the electric 15 is not great, so the LED 3-way clock of the ship can be The arrangement of the second embodiment of the advertisement of the present invention includes a light source 7 and a programmable light source controller 72 and: ^. Although the user finishes editing the comparison information, the cable can be utilized. The signal is transmitted to the programmable wire controller. The wired transmission can be connected to the host computer by the cable or the transmission line. The benefit line blue or wireless network transmits the comparison information to the programmable code. The wireless module 'group 75 can be electrically connected to the programmable light receiving comparison information 74 and the comparison information 74 can be input to the first type of the hybrid service 72 by means of no _ road to compare the i, the field line f group 75. Cheng U Chi _ 72 Kegen Beixing 74 driving light source 71 produces different brightness contrasts at different times. 'Please refer to item 8, which is the intent of the advertising light box of the present invention. The wide wire box 80 includes a light source 81 and a programmable In the light ^ _, the user can = record more information. The code reader 85 is electrically connected to the light source: H82, which is used to read the barcode 86 to obtain the comparison information 84, and input the ratio/capacity 84 into the programmable light source controller 82. Thus, After that, the programmable light source controller 82 can read the bar code 86 on the back of the image, and the 201241801 moving light source 81 produces different brightness contrasts at different times. Please refer to FIG. 9 is a schematic view of a fourth embodiment of the advertising light box of the present invention. The advertising light box 90 includes a light source 9 and a programmable light source controller % and a sensor 95. The sensor % senses the transmittance of the printed image 93 and generates a plurality of contrast information 94 based on the transmittance of the printed image 93. In this embodiment, the user does not need to edit the comparison information 84, and the programmable light source controller 82 can generate the reshaping information 84 by the transmittance of the printed image 83 by the sensor 95. According to the comparison information 84, the driving light source 81 generates different brightness contrasts at different times. Please refer to FIG. 10'. FIG. 10 is a flow chart of the light source of the (4) advertising light box of the present invention. The advertising light box comprises a light source, a plurality of noise-like and programmable light source controllers, and the method for controlling the light source of the advertising light box comprises the following steps: Step 101: Install the printed image in the advertising light box. Step 102: Compare the information according to the content of the printed image. The user can edit the multiple comparison information on the computer host, or use the barcode to record the comparison information on the back of the printed image. In addition, the programmable light source controller can generate contrast information by sensing the transmittance of the printed image by the sensor. Step H will compare the information input to the programmable light source. The user can store the comparison information in the external memory and then electrically connect to the programmable light source controller, or transmit the contrast information through the wired or wireless transmission to the private light source controller. In addition, the programmable light source controller can obtain the ratio information according to the bar code on the back side of the printed image by the barcode reader. Step 104: The y program control unit generates different brightness contrasts according to different periods of time. For example, the programmable light source controller drives the light source with the same driving current, and uses the control signals of different periods to generate a high-brightness flashing backlight in the highlighted area, and generates a low-brightness continuous backlight in the normal production 201241801. f, ίίΓρΐ ‘The present invention provides a stylized dynamic effect advertising light j The brightness can be individually controlled to achieve the purpose of emphasizing light and power saving.
