The parallel Linear LED driver channel structure associated with the power conversion stage covers mainstream applications for many LED Lighting dimming and color tuning applications. Given the maximum operating input voltage at 60V, it is possible to drive more than 16 RGB emitters by splitting LED Emitter string voltage and VIN, as long as it is below 60V.The AL1783 is a three PWM current sink regulator. In order to meet channel current accuracy and short protection requirements, the recommended maximum current of each channel is 250mA and the recommended minimum channel current is 30mA. Each channel can be individually and digitally controlled by the PWM dimming the signal down to less than 1%@1kHz.As in the case of three-channel Tunable Color LED lighting, the AL1783 drives three emitter strings. Using R REF1, R REF2, and R REF3of 24KΩ, the maximum output current for Channel 1, Channel 2, and Channel 3 will be 250mA when each PWM signal is turned on. The associated micro-controller unit (MCU) shall program and generate the suitable PWM duty cycle to meet the required and targeted Tuning Color output. R REF1,R REF2, and R REF3 can also be set dynamically for different peak values to achieve the desired channel peak current if another dimension adjustment is needed.The LED Driving Element detects fault conditions and reports its status on the FAULTB pin. It features LED open detection, LED short detection, Over Temperature Protection (OTP), and Under Voltage Lockout (UVLO). The AL1783 provides supreme current matching between channels and devices. Along with bus-mode fault reporting, multiple devices can be employed together to increase current driving capabilities or channel count versatility.Interface with Emitter StringsThe Power Conversion stage provides necessary constant output voltages (CVs) to power the micro-controller unit (MCU), LED Strings, and LED Drivers. A typical application requires 3.3V for the MCU and 12V/24V/48V anodes of LED emitter strings. The cathodes of the bottom LED emitter strings are connected to the LED1,2,3 pins of the AL1783.Interface with MCUThe physical layer interfaces between the micro-controller unit (MCU) and the AL1783 are the PWM1,2,3 pins and FAULTB. The MCU activates the PWM1,2,3 (asserted high) to turn on AL1783 during normal LED lighting operation applications. When the PWM1,2,3 pins are asserted low and greater than > 4ms, the device enters into Standby Mode with minimum power consumption. For typical light dimming or mixing operations, the MCU generates proper dimming control output signals to the PWM1,2,3 pins. If any general fault occurs in the AL1783, the FAULTB pin is asserted LOW to interrupt and request the MCU to take proper actions.Application Information (cont.)Current SettingThe AL1783 is designed to have individual LED channel currents set by its corresponding current setting from the R SET1,2,3resistor. The LED channel current level is expressed as below:ILED1,2,3=4000∗VREFRSET1,2,3wℎere VREF=1.5V nominally for all cℎannelsFor example, when an R REF of 24KΩ is used, each channel of the AL1783 provides the same output current of 250mA.The maximum LED current for each channel can be adjusted up to 250mA via the R REF resistor for AL1783. Any two or more channels can be tied together to drive one LED string with aggregated current. So when the current needed for any channel is greater than the maximum value the device can provide, two or more channels or devices can be connected and paralleled together to provide the higher drive current necessary. Support Higher CurrentWhile the recommended maximum operating current is at 250mA for each channel, and total 750mA for the AL1783, by setting R REF1, R REF2, and R REF3 at 24KΩ; the system design can drive an LED string with higher current by connecting the cathodes of the LED emitter string to two or more LED channel outputs (LED1,2,3) and tie the associated PWM pins (PWM1,2,3) to the same PWM signal from the MCU. The total current through the LED emitter string is the sum of the current through each individual channel.Similarly, it is also possible to further increase the current for a specific LED string by connecting two or more AL1783 IC chips in parallel and drive all associated PWM pins with a common PWM signal.PWM Dimming ControlA PWM frequency greater than 500HZ is recommended. A high level of PWM signals will turn the current sink on to flow through the LED pin, and a low level will turn it off. Consequently, each LED channel and LED brightness of the corresponding channel can be adjusted cycle-by-cycle accordingly.The pulse width of the PWM signal should be no less than 10μs, supporting down to 1% @ 1 kHz deep dimming capability. PWM signals can be driven static high/low to turn on/off the corresponding channels.Enable and Soft-Start LED Drivers (EN Pin)The PWM of the AL1783 is enabled when the voltage at any PWM1,2,3 pin is greater than the typical voltage of 2.5V, and disabled when all PWM1,2,3 are lower than 0.4V. When PWM1,2,3 pin is asserted and the VIN pin is ramped up beyond minimum operation voltage, a soft start will be performed with a slew-rate controlled current ramp over 200μS at the LED1,2,3 output pins. For optimal system reliability, this minimizes the current overshooting through the LED strings. When all PWM1,2,3 are asserted low for > 4ms, the LED Driver will enter into Standby Mode with ultra-low standby power < 200μA.Standby ModeWhen in this Standby Mode, the power consumption saved is I vin_standby (Standby Power Supply Current) * VIN (VIN for LED driver circuit). Refer to the case of the R REF at 24KΩ (fo r 250mA channel current in the AL1783, I standby is typical at 0.2mA) and VIN is 50V, or 10mW for the LED driver portion.When any PWM signal driving AL1783 is detected, the AL1783 will automatically exit the standby mode and perform the designated functions properly.Application Information (cont.)Fault Reporting (FAULTB Pin)The AL1783 detects and reports the FAULTB status upon the occurrence of Thermal Shutdown in OTP, LED Short, LED Open, and UVLO. The FAULTB pin is an open-drain output design. Multiple devices can share a single FAULTB signal by connecting all FAULTB pins together with an external pull-up resistor.Under Voltage Lockout (Hysteresis Mode)Under-voltage lockout function (UVLO) guarantees that the device is initially off during start-up. The AL1783 is not turned ON until the power supply has reached 6V. Whenever the input voltage falls below approximately 5.7V, the device is turned off and the FAULTB status will be reported. The UVLO detection-trigger circuitry has a hysteresis of 300mV.LED Open Protection (Hiccup Mode)The AL1783 detects the LED status by monitoring the current of the LED pin. When LED opens and lasts for a period of time period, the AL1783 enters protection mode and shuts down all channels. The time period is 7 cycles of the input PWM signal or 3ms timer when the PWM duty is 100%. The abnormal channel will be retested afterward to check if the abnormal condition is cleared. The AL1783 periodically checks every 128ms if the abnormal condition is removed. The LED driver will re-activate once the abnormal condition is cleared. The LED open protection is effective when the input PWM1,2,3 signal on time is higher than 10μs, or 1% @ 1 kHz. The FAULTB pin will be asserted low when the LED pin detects that the LED string is open, and will resume high once the LED open condition is removed.LED Short Protection (Hiccup Mode)The AL1783 detects the LED status by monitoring voltage at the LED1,2,3 pins. When the LED string anode is short to cathode, V LED1,2,3 will be pulled up. When V LED1,2,3 voltage exceeds 15V and lasts for a short time period, the AL1783 enters protection mode and shuts down all channels. The time period is 7 cycles of the input PWM signal or 3ms timer when the PWM duty is 100%. The abnormal channel will be periodicallyrechecked every 128ms afterward to detect if the abnormal condition is cleared. The LED driver will re-activate once the abnormal condition iscleared. The LED short protection is effective when the input voltage is higher than 15V and the input PWM1,2,3 signal on time is higher than 10μs, or 1% @ 1 kHz. The FAULTB pin will be asserted low when the LED shorts, and will resume high once the LED short condition is removed.Thermal Foldback and Over Temperature Protection (Hysteresis Mode)Temperature is a concern when driving the LEDs at high currents. Take care at high temperatures so as to not exceed the LED operating temperature requirements. In order to cool down the LEDs before they are damaged, the current going through the LEDs must be decreased when the LED temperature begins to increase.When the chip temperature is higher than the threshold temperature (130°C), the AL1783 starts to reduce the V REFX voltage and the LED current starts to fall from the nominal current. As illustrated in Figure 3, the LED current decreases as the temperature increases.L E D C u r r e n t P e r c e n t a g e (%)Temperature (ºC)Figure 3. Thermal Fold-back DiagramThermal protection prevents the IC from being damaged when the temperature exceeds safe margins. When the junction temperature reaches 160ºC, the device will enter thermal shut down, and all currents will sink and while no current flows to the LED strings. The normal current level can be automatically restored to its set current from OTP by triggering a Soft Start once the temperature cools down below 140ºC. The LED Driver’s Thermal Shut Mode will also be reported at the FAULTB pin.Ordering InformationAL1783 T16E - XPackageT16E: TSSOP-16EP13: Tape & ReelProduct NamePackingPart Number Package CodePackaging 13” Tape and ReelQuantityPart Number SuffixAL1783T16E-13T16ETSSOP-16EP (Type DX)(Note 8)2500/Tape & Reel-13Note:8.

赛米控CAT3647 3通道超高效率LED驱动器 32级调光说明书
CAT36473-Channel Ultra High Efficiency LED Driver with 32 Dimming LevelsDescriptionThe CAT3647 is a high efficiencye fractional charge pump that can drive up to three LEDs programmable by a one wire digital interface. The inclusion of a 1.33x fractional charge pump mode increases device efficiency by up to 10% over traditional 1.5x charge pumps with no added external capacitors.Low noise input ripple is achieved by operating at a constant switching frequency which allows the use of small external ceramic capacitors. The multi−fractional charge pump supports a wide range of input voltages from 2.4 V to 5.5 V.The EN/DIM logic input functions as a chip enable and a digital dimming interface for setting the current in all the LED channels. The 1−wire pulse−dimming interface supports 32 linear steps from full−scale down to zero current.The device is available in the tiny 16−pad TQFN 3mm x 3mm package with a max height of 0.8mm.ON Semiconductor’s 1.33x, charge pump switching architecture is patented.Features•High Efficiency 1.33x Charge Pump•Charge Pump: 1x, 1.33x, 1.5x, 2x•Drives up to 3 LEDs at 30 mA Each•1−wire EZDim 32 Linear Steps•Power Efficiency up to 92%•Low Noise Input Ripple in All Modes•“Zero” Current Shutdown Mode•Soft Start and Current Limiting•Short Circuit Protection•Thermal Shutdown Protection•16−pad TQFN Package•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS CompliantApplications•LCD Display Backlight•Cellular Phones•Digital Still Cameras•Handheld DevicesTQFN−16HV3 SUFFIXCASE 510ADPIN CONNECTIONSMARKING DIAGRAMDevice Package Shipping†ORDERING INFORMATIONCAT3647HV3−GT2(Note 1)TQFN−16(Pb−Free)2,000/Tape & Reel 1.NiPdAu Plated Finish (RoHS−compliant).LED1GNDNCNCC2−C2+C1−C1+LED2LED3NCRSETEN/DIMVOUTNCVIN1(Top View)JAAPAXXXYWWJAAP = CAT3647HV3−GT2A = Assembly LocationXXX = Last Three Digits of Assembly Lot Number Y = Production Year (Last Digit)WW = Production Week (Two Digits)†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our T ape and Reel Packaging Specifications Brochure, BRD8011/D.Figure 1.

A small 1m F ceramic bypass capacitor is required between the VIN pin and ground near the device. The operating input voltage range is from 2.5V to 5.5V. Whenever the input supply falls below the under-voltage threshold (1.8V), all the LED channels are disabled and the device enters shutdown mode. EN/DIM is the enable and one wire dimming input for all LED channels. Levels of logic high and logic low are set at 1.3V and 0.4V respectively. When EN/DIM is initially taken high, the device becomes enabled and all LED currents are set to the full scale according to the resistor R SET. To place the device into “zero current” shutdown mode, the EN/DIM pin must be held low for at least 1.5ms. VOUT is the charge pump output that is connected to the LED anodes. A small 1 m F ceramic bypass capacitor is required between the VOUT pin and ground near the device. GND is the ground reference for the charge pump. The pin must be connected to the ground plane on the PCB.C1+, C1- are connected to each side of the ceramic bucket capacitor C1.C2+, C2- are connected to each side of the ceramic bucket capacitor C2.LED1, LED2, LED3 provide the internal regulated current sources for each of the LED cathodes. These pins enter high-impedance zero current state whenever the device is placed in shutdown mode.TAB is the exposed pad underneath the package. For best thermal performance, the tab should be soldered to the PCB and connected to the ground plane.RSET is connected to the resistor (R SET) to set the full scale current for the LEDs. The voltage at this pin regulated to 0.6V. The ground side of the external resistor should be star connected back to the GND of the PCB. In shutdown mode, RSET becomes high impedance.Block DiagramFigure 24. CAT3647 Functional Block DiagramBasic OperationAt power-up, the CAT3647 starts operating in 1x mode where the output will be approximately equal to the input supply voltage (less any internal voltage losses). If the output voltage is sufficient to regulate all LED currents, the device remains in 1x operating mode.If the input voltage is insufficient or falls to a level where the regulated currents cannot be maintained, the device automatically switches into 1.33x mode (after a fixed delay time of about 120 m s). In 1.33x mode, the output voltage is approximately equal to 1.33 times the input supply voltage (less any internal voltage losses).This sequence repeats in the 1.33x and 1.5x mode until the driver enters the 2x mode. In 1.5x mode, the output voltage is approximately equal to 1.5 times the input supply voltage. While in 2x mode, the output is approximately equal to 2 times the input supply voltage.If the device detects a sufficient input voltage is present to drive all LED currents in 1x mode, it will change automatically back to 1x mode. This only applies for changing back to the 1x mode. The difference between the input voltage when exiting 1x mode and returning to 1x mode is called the 1x mode transition hysteresis (V HYS) and is about 400 mV.LED Current SelectionAfter power-up, the LED current is set by the external resistor (R SET ) value and the number of pulses (n) on the EN/DIM input as follows:LED current +125 0.6VR SETǒ31*n31ǓThe full scale current is calculated from the above formulawith n equal to zero.The EN/DIM pin has two primary functions. One function enables and disables the device. The other function is LED current dimming with 32 different levels by pulsing the input signal, as shown on Figure 25. On each consecutive pulse rising edge, the LED current is decreased by about 3.2%(1/31th of the full scale value). After 30 pulses, the LED current is 3.2% of the full scale current. On the 31st pulse, the current drops to zero, and then goes back to full scale on the following pulse.Each pulse width should be between 200ns and 100m s.Pulses faster than the minimum T LO may be ignored and filtered by the device. Pulses longer than the maximum T LO may shutdown the device. By pulsing the EN/DIM signal at high frequency, the LED current can quickly be set to zero.The LED driver enters a “zero current” shutdown mode if EN/DIM is held low for 1.5ms or more.The dimming level is set by the number of pulses on the EN/DIM after the power-up, as shown in Table 7.Table 7. DIMMING LEVELSFull Scale Current in %Dimming Pulses [n]1000971942903874845816777748719681065116112581355145215481645174218391935203221292226232324192516261327102862933003110032Figure 25. EN/DIM Digital Dimming Timing DiagramLEDUnused LED ChannelsFor applications not requiring all the channels, it is recommended the unused LED pins be tied directly to VOUT (see Figure 26).Figure 26. Application with 2 LEDsProtection ModeIf an LED is disconnected, the driver senses that and automatically ignores that channel. When all LEDs are disconnected, the driver goes to 1x mode where the output is equal to the input voltage.As soon as the output exceeds about 6V , the driver resets itself and re-evaluates the mode.If the die temperature exceeds +150°C, the driver will enter a thermal protection shutdown mode. When the device temperature drops by about 20°C, the device will resume normal operation.LED SelectionLEDs with forward voltages (V F ) ranging from 1.3V to 4.3V may be used. Selecting LEDs with lower V F is recommended in order to improve the efficiency by keeping the driver in 1x mode longer as the battery voltage decreases.For example, if a white LED with a V F of 3.3 V is selected over one with V F of 3.5 V , the driver will stay in 1x mode for lower supply voltage of 0.2 V . This helps improve the efficiency and extends battery life.External ComponentsThe driver requires four external 1 m F ceramic capacitors for decoupling input, output, and for the charge pump. Both capacitors type X5R and X7R are recommended for the LED driver application. In all charge pump modes, the input current ripple is kept very low by design and an input bypass capacitor of 1 m F is sufficient.In 1x mode, the device operates in linear mode and does not introduce switching noise back onto the supply.Recommended LayoutIn charge pump mode, the driver switches internally at a high frequency. It is recommended to minimize trace length to all four capacitors. A ground plane should cover the area under the driver IC as well as the bypass capacitors. Short connection to ground on capacitors C IN and C OUT can be implemented with the use of multiple via. A copper area matching the TQFN exposed pad (TAB) must be connected to the ground plane underneath. The use of multiple via improves the package heat dissipation.Figure 27.

3LED的DLP投影有哪些优势？
3LED的DLP投影有哪些优势？目前来讲，LED一般与（TI）DLP技术的投影技术搭配。
最早的DLP 投影使用的是色轮显色，难免有彩虹效应亮度不高等缺点；后来出现了LED，使用3原色Led灯泡直接发光就解决了这个问题。
不过，led灯在目前看来亮度没有高压汞灯那么高，但普通民众对于使用LED灯的投影还是所有抗拒。
那么，使用LED灯的投影有什么优势呢？一、使家用投影更加“随身化”和“自由化”LED光源的应用，在投影机方面，未来的发展方向是移动商务应用以及家用。
其可交直流两用，短焦，投影距离3米左右画面最大可达120英寸，屏幕亮度350-700流明，随着技术的发展，显示效果还在不断提升。
其最主要的意义在于为机身小型化开辟了新的道路。
由于LED 光源体积小，且具有很多显示技术优点，所以更适于研发小巧的投影机甚至原件，使用户的投影更加“随身化”和“自由化”。
例：（上图）一个巴掌就可以轻松托起来的投影仪，极客投GT-1。
二、方便各个角度投影。
目前，LED光源主要应用于集成化小型投影原件和袖珍式小型机两种投影产品，集成化小型投影原件不做成独立机型，其主要是与微型显示设备如手机、数码相机、笔记本电脑集成在一起，电池供电，可以投影约A4纸或标准信纸大小的图像，方便与他人共享画面。
袖珍式掌上投影机则是完整独立机型：体积小巧轻便，一只手也可以轻易的拿起，携带方便，可放于文件包内，同时由于有梯形纠正功能，也方便各个角度投影，效果不错。
极客投GT-1投在墙上的效果极客投GT-1投到天花板上的效果极客投GT-1在强光下配合全息投影幕布进行背投的效果。
三、寿命增加，性能更好LED用于投影照明，不仅寿命增加（长达30000小时），而且改变了投影机结构。
由于减少了散热需求，并缩短了光路系统，所以散热量和噪声都有更好的表现。
例：上图投影仪极客投GT-1侧边的金属围边都布满了散热孔，使机器能够充分散热。
四、显色优秀最早的DLP投影使用的是色轮显色。
一台电脑控制多个LED显示屏
一台电脑控制多个显示屏一、说明现场有三块不同大小，不同规格的显示屏LED1、LED2、LED3（三个显示屏面积分别为LED1：16扫的双色屏256*128像素点，LED2：8扫的全彩显示屏128*256像素点，LED3： 静态的全彩显示屏256*256像素点。
）三个显示屏上分别显示不同的节目内容。
所需要的硬件设备有：电脑—千兆网卡—卡莱特的控制器—转接板—显示屏（卡莱特的T9、A8、5A都可以作为这里的控制器）效果图（01图）二、软件设置1、配置屏幕参数分别单独对每一块LED 显示屏进行参数设置，保存参数文件LED1.DAT；LED2.DAT；LED3.DAT。
（具体参数设置步骤请参照《LEDSHOWT9调试步骤》）2、设置屏幕数量打开“控制屏幕”→“屏幕管理”，进入屏幕管理界面，设置屏幕数为“3”。
此时，软件自动生成三个LED屏幕，根据实际LED显示屏的规格分别设置LED屏幕的大小256*128，128*256，256*256.设置界面（02图）注：设置好后，图02中的LED1，LED2，LED3与实际显示屏之间是一一对应的，关系不会再改变。
3、加载屏幕参数将电脑与第一块LED显示屏用网线进行直连，在软件的“屏幕管理”中选择LED1（选中的底色为蓝色）如图02，点击“配置选中屏参数…”，输入密码“168”，进入“接收卡参数设置LED1”界面，点击“从文件加载…”加载第一步获得的“LED1.DAT”，并“发送到接收卡”。
断开网线，重复上一步骤发送LED2，LED3显示屏的参数。
12加载参数（03图）注意: A. 加载屏幕参数的过程中，电脑必须与要加载参数的一个LED 显示屏直连，其它LED显示屏的网线必须断开。
B. 在设置LED2，LED3时要在控制区域处选择正确LED屏号，再发参数。
（如图2）三、硬件连接卡莱特的控制系统在软件设置好后，硬件连接就相当灵活，客户可以根据施工现场的实际环境进行硬件连接，总结后主要有以下三种方案。
第三代非隔离高恒流精度高功率密度LED驱动技术
用于世界范围内不同电网的恒流。图 9 的线性调整率接近 0， 这是因为芯片逐周期闭环控制，立刻响应，不会引起输出电 流变化。在实现如此理想的线性调整率的同时，还省却了第 二代控制芯片因为线性补偿的许多外围元器件，同时提升的 是电路的可靠性。 高负载调整率的实际意义，是多套灯负载可以用一套电 源。例如 12 串输出是 36V 左右，24 串输出是 72V 左右，如 果设计电流值相同，可以使用同一套电源，对于电源厂，在 生产中对于备料、库存管理有显著价值。值得一提的是，如 图 10，此系统在短路的时候依然实现了恒流，这就意味着： ① 短路保护通过最安全的方式实现；② 这是真正意义的全负 载恒流。

要：文章详细介绍了基于 TRUEC2（True Constant Current 的缩写）技术非隔离 BUCK 拓扑，来实现极高精度 LED 恒流控制。
试验证明，全闭环 TRUEC2 技术实时检测真实输出电流，免受输入电压、外部电感影响，突破性地提高了 LED 输出电流的精度。 集成 MOSFET，简化外围线路；控制方式免受电感影响，可选择更低价的工字型电感，提高可靠性的同时降低了成本，受到市 场广泛欢迎。 关键词：TRUEC2 LED 恒流控制 全闭环电流控制 DU8623 DU8633 Abstract: This paper presents the principle of a non-isolated BUCK topology based on TRUEC2 constant current control, using integrated MOSFET PWM control IC: Duty Cycle Company’s DU8623 and DU8633. The experiment demonstrates that this control method can effectively increase the accuracy of the output current, which is not subject to the line voltage and external inductor. The Robustness is also increased compare with open loop control solution. The integration of MOFET results in the decreasing of external components, which in turn decreases total cost.

三色发光二极管原理图 LED三色调光的概念
三色发光二极管原理图 LED三色调光的概念三色LED的概念三色LED由两个不同颜色的管芯组成，有共阳、共阴接法，故为散引脚。
当两个管芯各自亮时呈现两色，当两个管芯一起亮时则为混色，所以称为三色LED。
三色发光二极管是将3种不同颜色的LTC4151CMS%23PBF管芯封装在一起，也分为共阴极和共阳极两种。
三色发光二极管接线图共阴极4个引脚的三色发光二极管内部结构如图4-52所示，3种发光颜色（如红、蓝、绿三色）的管芯负极连接在一起。
4个引脚中，1脚为绿色发光二极管的正极，2脚为蓝色发光二极管的正极，3脚为公共负极，4脚为红色发光二极管的正极。
使用时，公共负极3脚接地，其余引脚按需要接入工作电压即可。
带阻发光二极管带阻发光二极管又称电压型发光二极管，其电路结构如图4-54所示。
带阻发光二极管已将限流电阻做到了发光二极管内，只要接入规定的直流电压即可发光。
浅谈led三色调光led三色调光就是RBG 三种颜色的反光粉，当调整LED的驱动电流时，LED 的颜色会随变化。
配合控制器后可以调整任意颜色，并且支持编程的，这个一般用在LED 洗墙灯和LED 灯条上。
作为一种光源，调光是很重要的。
不仅是为了在家居中得到一个更舒适的环境，在今天来说，减少不必要的电光线，以进一步实现节能减排的目的是更加重要的一件事。
而且对于LED光源来说，调光也是比其他荧光灯、节能灯、高压钠灯等更容易实现，所以更应该在各种类型的LED灯具中加上调光的功能。
一、用调正向电流的方法来调亮度 要改变LED的亮度，是很容易实现的。
首先想到的是改变它的驱动电流，因为LED的亮度是几乎和它的驱动电流直接成正比关系。
图1中显示了Cree公司的XLamp XP-G 的输出相对光强和正向电流的关系。
由图中可知，假如以350mA时的光输出作为100%，那么200mA时的光输出就大约是60%，100mA时大约是25%.所以调电流可以很容易实现亮度的调节。
