Abstract
本發明係一種燈板裝置，其包含有第一簇發光單元、第二簇發光單元及燈板控制單元。燈板控制單元依序產生並輸出第一簇控制訊號及第二簇控制訊號至第一簇發光單元及第二簇發光單元，以控制第一簇發光單元於第一時間段發光，且控制第二簇發光單元於第二時間段發光。燈板裝置通過分時發光的方式，讓第一簇發光單元及第二簇發光單元在眼睛視覺暫留期間交替發光。如此一來，人眼視覺無論何時都可感受到第一簇發光單元及第二簇發光單元所發出的共同照明效果而不會減少光亮，且可降低第一簇發光單元及第二簇發光單元同時發光造成的散熱問題。The present invention is a light panel device, which includes a first cluster of light-emitting units, a second cluster of light-emitting units, and a light panel control unit. The light panel control unit sequentially generates and outputs a first cluster of control signals and a second cluster of control signals to the first cluster of light-emitting units and the second cluster of light-emitting units to control the first cluster of light-emitting units to emit light in a first time period and to control the second cluster of light-emitting units to emit light in a second time period. The light panel device uses a time-sharing lighting method to allow the first cluster of light-emitting units and the second cluster of light-emitting units to alternately emit light during the period of temporary visual retention of the eyes. In this way, the human eye can always feel the common lighting effect emitted by the first cluster of light-emitting units and the second cluster of light-emitting units without reducing the brightness, and can reduce the heat dissipation problem caused by the simultaneous lighting of the first cluster of light-emitting units and the second cluster of light-emitting units.
Description
一種燈板裝置，尤指一種能夠減少發熱的燈板裝置。 A light panel assembly, especially one that reduces heat generation.
一般燈板裝置上會設置一發光單元陣列，例如發光二極體(LED)陣列，LED陣列係將複數LED呈矩陣形式設置於一燈板的一發光面上。而該燈板之一被光面會設有一散熱裝置。由於該LED陣列中的LED數量已達數萬顆之多，因此，該些LED發光時所產生的熱量也相當驚人。而通常會通過設置於該燈板之該背光面的該散熱裝置進行散熱，避免溫度過高造成該燈板裝置的損毀。 A typical light panel device is equipped with an array of light-emitting units, such as a light-emitting diode (LED) array. An LED array consists of multiple LEDs arranged in a matrix on a light-emitting surface of a light panel. A heat sink is installed on one of the illuminated surfaces of the light panel. Because the number of LEDs in an LED array can reach tens of thousands, the amount of heat generated by these LEDs when emitting light is considerable. This heat is typically dissipated through a heat sink located on the backlight surface of the light panel to prevent damage to the light panel device caused by excessive temperatures.
但現有通過該散熱裝置進行散熱的方式，仍有其限制。例如當該些LED產生的熱量過多，或是發光時間較長的時候，仍會有來不及散熱造成過熱的情況。因此，目前另有通過脈波寬度調變(Pulse-width modulation，PWM)調光的方式對該些LED進行控制，使其依次發光，避免該些LED同時發光，進而減少該些LED產生的熱量，藉此降低溫度，避免溫度過高。舉例來說，當控制該些LED發光的工作週期為50%時，代表在一個時間周期內，該些LED僅有50%的時間會發光。且通過視覺暫留原理，當該時間周期控制小於一預設值時，即便該些LED會有50%的時間不發光，人眼也無法察覺，藉此提供照明功能，且同時能減少熱量的產生。 However, existing heat dissipation methods using heat sinks still have limitations. For example, when the LEDs generate too much heat or their lighting time is long, they may not be able to dissipate the heat quickly enough, causing overheating. Therefore, there is currently an alternative method of controlling the LEDs through pulse-width modulation (PWM) dimming, which prevents them from lighting up simultaneously. This reduces the heat generated by the LEDs, thereby lowering the temperature and preventing them from overheating. For example, when the duty cycle of controlling the LEDs to light up is 50%, it means that within a time period, the LEDs will only light up 50% of the time. Furthermore, through the principle of visual retention, when the time period is controlled to be less than a preset value, even if the LEDs are not emitting light 50% of the time, the human eye will not be able to detect it, thereby providing lighting function and reducing heat generation.
然而，現有技術通過調光對該些LED進行控制，用以降低溫度的方式，仍會有閃爍情況產生，導致照明效果被影響，故仍需進一步之改良。 However, existing technologies that control these LEDs through dimming to reduce temperature still cause flickering, affecting the lighting effect, and therefore require further improvement.
有鑑於現有的燈板裝置通過調光控制，用以降低溫度的方式，仍可能因為閃爍，導致照明效果受到影響的缺點，本發明提供一種新式的燈板裝置。該燈板裝置包含有複數第一簇發光單元、複數第二簇發光單元及一燈板控制單元。 In view of the drawback that existing light panel devices, which use dimming control to reduce temperature, may still suffer from flickering, which may affect the lighting effect, the present invention provides a novel light panel device. The light panel device includes a plurality of first clusters of light-emitting units, a plurality of second clusters of light-emitting units, and a light panel control unit.
該燈板控制單元電連接該些第一簇發光單元及該些第二簇發光單元。該燈板控制單元依序產生並輸出一第一簇控制訊號及一第二簇控制訊號至該些第一簇發光單元及該些第二簇發光單元，以控制該些第一簇發光單元於一第一時間段發光，且控制該些第二簇發光單元於一第二時間段發光。 The light panel control unit is electrically connected to the first cluster of light-emitting units and the second cluster of light-emitting units. The light panel control unit sequentially generates and outputs a first cluster control signal and a second cluster control signal to the first cluster of light-emitting units and the second cluster of light-emitting units to control the first cluster of light-emitting units to emit light during a first time period and the second cluster of light-emitting units to emit light during a second time period.
由於本發明的該燈板裝置具有該些第一簇發光單元及該些第二簇發光單元，且該些第一簇發光單元係於該第一時間段發光，於該第二時間段不發光，而該些第二簇發光單元係於該第二時間段發光，於該第一時間段不發光，該燈板裝置即可通過分時發光的方式，讓該些第一簇發光單元及該些第二簇發光單元交替發光。如此一來，無論何時都會有發光單元發光，不會有全暗的時刻。因此使用者無法察覺到該燈板裝置發出的光線有閃爍的狀態，藉此讓照明效果不會受到影響，提供良好的照明效果。 Because the light panel device of the present invention comprises the first and second clusters of light-emitting units, and the first clusters of light-emitting units illuminate during the first time period and remain off during the second time period, while the second clusters of light-emitting units illuminate during the second time period and remain off during the first time period, the light panel device can alternately illuminate the first and second clusters of light-emitting units using a time-sharing lighting system. This ensures that a light-emitting unit is always illuminated, preventing periods of complete darkness. Therefore, users cannot detect flickering light from the light panel device, maintaining optimal lighting performance.

請參閱圖1及圖2所示，本發明的燈板裝置10包含有複數第一簇發光單元101、複數第二簇發光單元102及一燈板控制單元11。 1 and 2 , the light panel device 10 of the present invention includes a plurality of first light-emitting units 101, a plurality of second light-emitting units 102, and a light panel control unit 11.
該燈板控制單元11電連接該些第一簇發光單元101及該些第二簇發光單元102。該燈板控制單元11依序產生並輸出一第一簇控制訊號及一第二簇控制訊號至該些第一簇發光單元101及該些第二簇發光單元102，以控制該些第一簇發光單元101於一第一時間段發光，且控制該些第二簇發光單元102於一第二時間段發光。 The light panel control unit 11 is electrically connected to the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102. The light panel control unit 11 sequentially generates and outputs a first cluster control signal and a second cluster control signal to the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102 to control the first cluster of light-emitting units 101 to emit light during a first time period and the second cluster of light-emitting units 102 to emit light during a second time period.
由於本發明的該燈板裝置10具有該些第一簇發光單元101及該些第二簇發光單元102，且該些第一簇發光單元101係於該第一時間段發光，於該第二時間段不發光，而該些第二簇發光單元102係於該第二時間段發光，於該第一時間段不發光，該燈板裝置10即可通過分時發光的方式，讓該些第一簇發光單元101及該些第二簇發光單元102交替發光。如此一來，無論何時都會有發光單元發光，不會有全暗的時刻。因此，使用者無法察覺到該燈板裝置發出的光線有閃爍的狀態，藉此讓照明效果不會受到影響，提供良好的照明效果。 Because the light panel device 10 of the present invention comprises the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102, and the first cluster of light-emitting units 101 illuminates during the first time period and not during the second time period, while the second cluster of light-emitting units 102 illuminates during the second time period and not during the first time period, the light panel device 10 can alternately illuminate the first and second clusters of light-emitting units 101 and 102 through time-sharing. This ensures that a light-emitting unit is always illuminated, preventing periods of complete darkness. Consequently, users cannot detect flickering light from the light panel device, maintaining a good lighting effect.
在本實施例中，該燈板控制單元11係通過一積體匯流排電路(I 2 C Bus)、一控制器區域網路(CAN Bus)或一乙太網路(Ethernet)電連接該些第一簇發光單元101及該些第二簇發光單元102。 In this embodiment, the light panel control unit 11 is electrically connected to the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102 via an integrated circuit bus ( I 2 C Bus), a controller area network (CAN Bus) or an Ethernet.
而該燈板裝置10還包含有一燈板12、一散熱單元13及一電源單元14。該燈板12具有相對的一發光表面121及一背光表面122。如圖1所示，該 散熱單元13係設置於該燈板12的該背光表面122。較佳的，該散熱單元13係一散熱鰭片或是一金屬散熱塊。該電源單元14電連接並供電給該燈板控制單元11、該些第一簇發光單元101及該些第二簇發光單元102。 The light panel device 10 further includes a light panel 12, a heat sink 13, and a power supply unit 14. The light panel 12 has a light-emitting surface 121 and a backlight surface 122 facing each other. As shown in Figure 1, the heat sink 13 is disposed on the backlight surface 122 of the light panel 12. Preferably, the heat sink 13 is a heat sink fin or a metal heat sink. The power supply unit 14 is electrically connected to and supplies power to the light panel control unit 11, the first cluster of light-emitting units 101, and the second cluster of light-emitting units 102.
請參閱圖3所示，在本實施例中，該些第一簇發光單元101及該些第二簇發光單元102係呈矩陣形式設置於該燈板12之該發光表面121，且該些第一簇發光單元101及該些第二簇發光單元102相互交錯設置。 Referring to FIG. 3 , in this embodiment, the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102 are arranged in a matrix on the light-emitting surface 121 of the light panel 12 , and the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102 are arranged in an interlaced manner.
請參閱圖4A、圖4B及圖5A、圖5B所示，舉例來說，如圖4A所示，當該燈板控制單元11產生並輸出該第一簇控制訊號至該些第一簇發光單元101時，該些第一簇發光單元101係於該第一時間段發光。如圖5A所示，圖5A為該第一簇控制訊號的波形圖，該第一簇控制訊號係於該些第一時間段產生，並且輸出至該些第一簇發光單元101，使該些第一簇發光單元101於該些第一時間段發光。而該第一時間段例如是一初始時間t0至一第一時間t1，或是一第二時間t2至一第三時間t3。 Please refer to Figures 4A, 4B, and 5A, 5B. For example, as shown in Figure 4A, when the light panel control unit 11 generates and outputs the first cluster control signal to the first cluster light-emitting units 101, the first cluster light-emitting units 101 emit light during the first time period. Figure 5A shows a waveform diagram of the first cluster control signal. The first cluster control signal is generated during the first time periods and output to the first cluster light-emitting units 101, causing the first cluster light-emitting units 101 to emit light during the first time periods. The first time period may be, for example, from an initial time t0 to a first time t1, or from a second time t2 to a third time t3.
進一步而言，如圖4B所示，當該燈板控制單元11產生並輸出該第二簇控制訊號至該些第二簇發光單元102時，該些第二簇發光單元102係於該第二時間段發光。如圖5B所示，圖5B為該第二簇控制訊號的波形圖，該第二簇控制訊號係於該些第二時間段產生，並且輸出至該些第二簇發光單元102，使該些第二簇發光單元102於該些第二時間段發光。而該第二時間段例如是該第一時間t1至該第二時間t2，或是該第三時間t3至一第四時間t4。 Furthermore, as shown in Figure 4B , when the light panel control unit 11 generates and outputs the second cluster control signal to the second cluster light-emitting units 102 , the second cluster light-emitting units 102 emit light during the second time period. As shown in Figure 5B , which is a waveform diagram of the second cluster control signal, the second cluster control signal is generated during the second time periods and output to the second cluster light-emitting units 102 , causing the second cluster light-emitting units 102 to emit light during the second time periods. The second time period may be, for example, from the first time t1 to the second time t2, or from the third time t3 to a fourth time t4.
此外，如圖5A及圖5B所示，該些第一時間段與該些該第二時間段相互接續。也就是說，當該些第一簇發光單元101結束發光的瞬間，該些第二簇發光單元102馬上接續發光，之間不會有空窗期。如此一來，該燈板裝置10無論何時都會有發光單元發光，不會有全暗的時刻。 Furthermore, as shown in Figures 5A and 5B, the first time periods and the second time periods are continuous. That is, the moment the first cluster of light-emitting units 101 cease emitting light, the second cluster of light-emitting units 102 immediately resume emitting light, with no intermittent period. This ensures that the light panel device 10 always has light-emitting units emitting light, ensuring there is no period of complete darkness.
此外，該些第一時間段及該些第二時間段互不重疊。該些第一簇發光單元101發光時，該些第二簇發光單元102不發光。而該些第二簇發光單元102發光時，該些第一簇發光單元101不發光。也就是說，該些第一簇發光單元101及該些第二簇發光單元102不會有同時發光的時候。如此一來，通過該些第一簇發光單元101及該些第二簇發光單元102的總電流就能有所限制。例如，同一時間點，只會有通過該些第一簇發光單元101的電流，或是只會有通過該些第二簇發光單元102的電流，不會有同時通過該些第一簇發光單元101及該些第二簇發光單元102的大電流。 Furthermore, the first time periods and the second time periods do not overlap. When the first cluster of light-emitting cells 101 emit light, the second cluster of light-emitting cells 102 do not. Conversely, when the second cluster of light-emitting cells 102 emit light, the first cluster of light-emitting cells 101 do not emit light. In other words, the first cluster of light-emitting cells 101 and the second cluster of light-emitting cells 102 never emit light at the same time. This limits the total current flowing through the first cluster of light-emitting cells 101 and the second cluster of light-emitting cells 102. For example, at any given time, only current will flow through the first cluster of light-emitting cells 101 or only through the second cluster of light-emitting cells 102; a large current will not flow through both the first cluster of light-emitting cells 101 and the second cluster of light-emitting cells 102 simultaneously.
舉例來說，若總電流的限流條件為10安培(A)，該些第一簇發光單元101及該些第二簇發光單元102的數量各為1000顆。若是在同一時間點，該些第一簇發光單元101及該些第二簇發光單元102需要一起發光時，則單一顆發光單元的限流為5毫安培(mA)。但若是同一時間點只有該些第一簇發光單元101需要發光，或是只有該些第二簇發光單元102需要發光時，則單一顆發光單元的限流為10毫安培(mA)。如此一來，單一顆發光單元的限流便可大幅提高，而通過發光單元的電流值又與其發光亮度呈正相關，也就是說，通過發光單元的電流值越大，發光單元的亮度越高。 For example, if the total current limit condition is 10 amperes (A), and the number of the first cluster of light-emitting units 101 and the number of the second cluster of light-emitting units 102 are each 1000, if at the same time, the first cluster of light-emitting units 101 and the second cluster of light-emitting units 102 need to emit light together, the current limit of a single light-emitting unit is 5 milliamperes (mA). However, if at the same time, only the first cluster of light-emitting units 101 or only the second cluster of light-emitting units 102 need to emit light, the current limit of a single light-emitting unit is 10 milliamperes (mA). This significantly increases the current limit of a single light-emitting unit. The current flowing through a light-emitting unit is positively correlated with its brightness. In other words, the greater the current flowing through the unit, the brighter the unit.
因此，在相同的限流條件下，通過該些第一簇發光單元101及該些第二簇發光單元102的電流便可增加，藉此提高該些第一簇發光單元101及該些第二簇發光單元102的發光亮度，進而達到提高該燈板裝置10的發光亮度的效果。在本實施例中，各該第一簇發光單元101於發光時的一第一發光電流I1係大於或等於1.4毫安培(mA)，且各該第二簇發光單元102於發光時的一第二發光電流I2係大於或等於1.4毫安培。 Therefore, under the same current limiting conditions, the current passing through the first and second clusters of light-emitting units 101, 102 can be increased, thereby improving the brightness of the first and second clusters of light-emitting units 101, 102, and thus achieving the effect of improving the brightness of the light panel device 10. In this embodiment, a first luminous current I1 of each first cluster of light-emitting units 101 when emitting light is greater than or equal to 1.4 milliamperes (mA), and a second luminous current I2 of each second cluster of light-emitting units 102 when emitting light is greater than or equal to 1.4 mA.
此外，在本實施例中，該第一時間段係小於或等於30毫秒(ms)，且該第二時間段係小於或等於30毫秒。如此一來，通過視覺暫留原理， 即便該些第一簇發光單元101或該些第二簇發光單元102會閃爍，人眼也無法察覺，藉此提供更佳的照明效果。 Furthermore, in this embodiment, the first time period is less than or equal to 30 milliseconds (ms), and the second time period is less than or equal to 30 milliseconds. Thus, through the principle of visual retention, even if the first cluster of light-emitting units 101 or the second cluster of light-emitting units 102 flickers, the human eye will not be able to detect it, thereby providing a better lighting effect.
進一步而言，該燈板控制單元11產生的該些第一簇控制訊號分別具有一第一位址資訊，且該些第一簇發光單元101具有該第一位址資訊。當該些第一簇發光單元101接收到一控制訊號時，該些第一簇發光單元101判斷該控制訊號中是否具有該第一位址資訊。當該控制訊號中具有該第一位址資訊時，該些第一簇發光單元101響應該控制訊號當該控制訊號中不具有該第一位址資訊時，該些第一簇發光單元101不響應該控制訊號。 Specifically, the first cluster control signals generated by the light panel control unit 11 each include a first address, and the first cluster light-emitting units 101 each include the first address. When the first cluster light-emitting units 101 receive a control signal, they determine whether the control signal includes the first address. If the control signal includes the first address, the first cluster light-emitting units 101 respond to the control signal. If the control signal does not include the first address, the first cluster light-emitting units 101 do not respond to the control signal.
此外，該燈板控制單元11產生的該些第二簇控制訊號分別具有一第二位址資訊，且該些第二簇發光單元102具有該第二位址資訊。當該些第二簇發光單元102接收到該控制訊號時，該些第二簇發光單元102判斷該控制訊號中是否具有該第二位址資訊。當該控制訊號中具有該第二位址資訊時，該些第二簇發光單元102響應該控制訊號。當該控制訊號中不具有該第二位址資訊時，該些第二簇發光單元102不響應該控制訊號。 Furthermore, the second cluster control signals generated by the light panel control unit 11 each include a second address, and the second cluster light-emitting units 102 each include the second address. Upon receiving the control signal, the second cluster light-emitting units 102 determine whether the control signal includes the second address. If the control signal includes the second address, the second cluster light-emitting units 102 respond to the control signal. If the control signal does not include the second address, the second cluster light-emitting units 102 do not respond to the control signal.
請參閱圖2及圖3所示，該燈板裝置10還包含有複數第三簇發光單元103。該燈板控制單元11進一步電連接該些第三簇發光單元103。該燈板控制單元11依序產生並輸出該第一簇控制訊號、該第二簇控制訊號及一第三簇控制訊號至該些第一簇發光單元101、該些第二簇發光單元102及該些第三簇發光單元103，以控制該些第一簇發光單元101於該第一時間段發光，且控制該些第二簇發光單元102於該第二時間段發光，並控制該些第三簇發光單元103於一第三時間段發光。 As shown in Figures 2 and 3, the light panel device 10 further includes a plurality of third-cluster light-emitting units 103. The light panel control unit 11 is further electrically connected to the third-cluster light-emitting units 103. The light panel control unit 11 sequentially generates and outputs the first-cluster control signal, the second-cluster control signal, and a third-cluster control signal to the first-cluster light-emitting units 101, the second-cluster light-emitting units 102, and the third-cluster light-emitting units 103, thereby controlling the first-cluster light-emitting units 101 to emit light during the first time period, the second-cluster light-emitting units 102 to emit light during the second time period, and the third-cluster light-emitting units 103 to emit light during a third time period.
請參閱圖6A至圖6C及圖7A至圖7C所示，舉例來說，如圖6A所示，當該燈板控制單元11產生並輸出該第一簇控制訊號至該些第一簇發光單元101時，該些第一簇發光單元101係於該第一時間段發光。如圖7A所示，圖7A 為該第一簇控制訊號的波形圖，該第一簇控制訊號係於該些第一時間段產生，並且輸出至該些第一簇發光單元101，使該些第一簇發光單元101於該些第一時間段發光。而該第一時間段例如是該初始時間t0至該第一時間t1，或是該第三時間t3至該第四時間t4。 Please refer to Figures 6A to 6C and 7A to 7C. For example, as shown in Figure 6A, when the light panel control unit 11 generates and outputs the first cluster control signal to the first cluster light-emitting units 101, the first cluster light-emitting units 101 emit light during the first time period. Figure 7A shows a waveform diagram of the first cluster control signal. The first cluster control signal is generated during the first time periods and output to the first cluster light-emitting units 101, causing the first cluster light-emitting units 101 to emit light during the first time periods. The first time period may be, for example, from the initial time t0 to the first time t1, or from the third time t3 to the fourth time t4.
進一步而言，如圖6B所示，當該燈板控制單元11產生並輸出該第二簇控制訊號至該些第二簇發光單元102時，該些第二簇發光單元102係於該第二時間段發光。如圖7B所示，圖7B為該第二簇控制訊號的波形圖，該第二簇控制訊號係於該些第二時間段產生，並且輸出至該些第二簇發光單元102，使該些第二簇發光單元102於該些第二時間段發光。而該第二時間段例如是該第一時間t1至該第二時間t2，或是該第四時間t4至一第五時間t5。 Furthermore, as shown in Figure 6B , when the light panel control unit 11 generates and outputs the second cluster control signal to the second cluster light-emitting units 102 , the second cluster light-emitting units 102 emit light during the second time period. As shown in Figure 7B , which is a waveform diagram of the second cluster control signal, the second cluster control signal is generated during the second time periods and output to the second cluster light-emitting units 102 , causing the second cluster light-emitting units 102 to emit light during the second time periods. The second time period may be, for example, from the first time t1 to the second time t2, or from the fourth time t4 to the fifth time t5.
再者，如圖6C所示，當該燈板控制單元11產生並輸出該第三簇控制訊號至該些第三簇發光單元103時，該些第三簇發光單元103係於該第三時間段發光。如圖7C所示，圖7C為該第三簇控制訊號的波形圖，該第三簇控制訊號係於該些第三時間段產生，並且輸出至該些第三簇發光單元103，使該些第三簇發光單元103於該些第三時間段發光。而該第三時間段例如是該第二時間t2至該第三時間t3，或是該第五時間t5至一第六時間t6。 Furthermore, as shown in Figure 6C , when the light panel control unit 11 generates and outputs the third cluster control signal to the third cluster light-emitting units 103, the third cluster light-emitting units 103 emit light during the third time period. As shown in Figure 7C , which is a waveform diagram of the third cluster control signal, the third cluster control signal is generated during the third time periods and output to the third cluster light-emitting units 103, causing the third cluster light-emitting units 103 to emit light during the third time periods. The third time period may be, for example, from the second time t2 to the third time t3, or from the fifth time t5 to the sixth time t6.
此外，如圖7A至圖7C所示，該些第一時間段、該些該第二時間段及該些第三時間段依序相互接續。也就是說，當該些第一簇發光單元101結束發光的瞬間，該些第二簇發光單元102馬上接續發光，且當該些第二簇發光單元102結束發光的瞬間，該些第三簇發光單元103馬上接續發光，之間不會有空窗期。如此一來，該燈板裝置10無論何時都會有發光單元發光，不會有全暗的時刻。 Furthermore, as shown in Figures 7A to 7C , the first time periods, the second time periods, and the third time periods follow one another sequentially. That is, the moment the first cluster of light-emitting units 101 cease emitting, the second cluster of light-emitting units 102 immediately resume emitting, and the moment the second cluster of light-emitting units 102 cease emitting, the third cluster of light-emitting units 103 immediately resume emitting, with no intermittent period. This ensures that the light panel device 10 always has light-emitting units emitting, preventing any periods of complete darkness.
此外，該些第一時間段、該些第二時間段及該些第三時間段互不重疊。也就是說，當該些第一簇發光單元101發光時，該些第二簇發光單元 102及該些第三簇發光單元103皆不發光。而當該些第二簇發光單元102發光時，該些第一簇發光單元101及該些第三簇發光單元103皆不發光。且當該些第三簇發光單元103發光時，該些第一簇發光單元101及該些第二簇發光單元102皆不發光。如此一來，該些第一簇發光單元101、該些第二簇發光單元102及該些第三簇發光單元103不會有同時發光的時候。 Furthermore, the first, second, and third time periods do not overlap. That is, when the first cluster of light-emitting cells 101 emit light, the second cluster of light-emitting cells 102 and the third cluster of light-emitting cells 103 do not emit light. Furthermore, when the second cluster of light-emitting cells 102 emit light, the first cluster of light-emitting cells 101 and the third cluster of light-emitting cells 103 do not emit light. Furthermore, when the third cluster of light-emitting cells 103 emit light, the first cluster of light-emitting cells 101 and the second cluster of light-emitting cells 102 do not emit light. In this way, the first cluster of light-emitting cells 101, the second cluster of light-emitting cells 102, and the third cluster of light-emitting cells 103 never emit light simultaneously.
在本實施例中，各該第三簇發光單元103於發光時的一第三發光電流I3係大於或等於1.4毫安培(mA)。該第三時間段係小於或等於30毫秒。 In this embodiment, a third luminous current I3 of each of the third cluster light-emitting units 103 when emitting light is greater than or equal to 1.4 milliamperes (mA). The third time period is less than or equal to 30 milliseconds.
進一步而言，該燈板控制單元11產生的該些第三簇控制訊號分別具有一第三位址資訊，且該些第三簇發光單元103具有該第三位址資訊。當該些第三簇發光單元103接收到該控制訊號時，該些第三簇發光單元103判斷該控制訊號中是否具有該第三位址資訊。當該控制訊號中具有該第三位址資訊時，該些第三簇發光單元103響應該控制訊號。當該控制訊號中不具有該第三位址資訊時，該些第三簇發光單元103不響應該控制訊號。 Furthermore, the third cluster control signals generated by the light panel control unit 11 each contain a third address, and the third cluster light-emitting units 103 contain the third address. When the third cluster light-emitting units 103 receive the control signals, they determine whether the control signals contain the third address. If the control signals contain the third address, the third cluster light-emitting units 103 respond to the control signals. If the control signals do not contain the third address, the third cluster light-emitting units 103 do not respond to the control signals.
