### COURSE DESCRIPTION

Fluorescent dimming extends the range of light levels provided by the lighting system with smooth, gradual transitions between levels.

Dimming provides flexibility for users to select light levels suitable for different visual needs, such as A/V presentations, meetings and individual preference.

Dimming also saves energy by reducing light levels in response to inputs such as daylight sensing, occupancy sensors, manual controls, time schedules and other devices—particularly in spaces in which people would find switching to be intrusive.

Fluorescent Dimming Ballasts is a two-part series that educates participants about dimmable fluorescent lighting. Part 1 describes how dimming ballasts work, the various types of dimmable ballasts and lamps, and dimming range and methods. By the end of the course, participants will have general knowledge enabling them to evaluate and select an appropriate dimming ballast for a given project.

### 课程简介

荧光灯调光延伸了照明系统提供的光线范围，光线在各级之间平滑、渐变。

调光为用户选择适合不同视觉需求的亮度提供了灵活性，例如 A/V 演示文稿、会议和个人偏好。

调光还可以通过降低光线水平来应对诸如日光感应、占用率传感器、手动控制、时间表和其他设备等输入，从而节省能源，尤其是在人们会觉得切换光线是一种干扰的空间。

荧光调光镇流器是一个两部分系列，教育参与者关于可调光荧光照明。第1部分介绍了调光镇流器的工作原理，各种类型的调光镇流器和灯具，以及调光范围和方法。课程结束时，学员将掌握一般知识，使他们能够评估和选择一个给定项目的适当的调光镇流器。

### LEARNING OBJECTIVES

At the end of the course, participants will be able to:

* have a working knowledge about how fluorescent lighting systems are dimmed, including the importance of a dimmable electronic ballast, and evaluate and select an appropriate dimming ballast for a given project.

* select ballasts that are dimmable as well as lamps they are rated to operate and sockets those lamps are compatible with.

* understand how dimming range is typically expressed, how this range is used to generally classify ballasts as architectural or energy management dimming ballasts, and how long a range is available for different ballast types.

* select fluorescent dimming ballasts based on dimming output, including step or continuous dimming, according to construction, including analog or digital, and based on dimming method, including two-wire, three-wire and four-wire.

### 学习目标

课程结束时，学员将能够:

* 了解荧光照明系统如何调光，包括可调光电子镇流器的重要性，并评估和选择一个特定项目的适当调光镇流器。

* 选择可调光的镇流器，以及额定可操作的灯具和插座，这些灯具兼容。

* 了解调光范围是如何通常表示，这一范围是如何使用一般分类镇流器的建筑或能源管理调光镇流器，以及有多长的范围是可用于不同类型的镇流器。

* 选择荧光调光镇流器的基础上调光输出，包括步进或连续调光，根据结构，包括模拟或数字，并根据调光方法，包括二线、三线和四线。

### THEORY OF OPERATION

Fluorescent ballasts provide starting voltage and subsequently regulate the current flowing through the lamp. Dimmable ballasts are designed to respond to control signals by changing the current flowing through the lamp, which reduces both light output and watts.

### 操作理论

荧光镇流器提供起动电压，随后调节流过灯的电流。可调光镇流器通过改变流过灯的电流来响应控制信号，从而减少了灯的输出功率和功率。

### STEP DIMMING

Step dimming provides a limited choice of light levels, with two or more preset increments between OFF and full  output. Typically, there is no fade between lighting states, so while technically the approach is dimming, the visual effect is the lights are being switched to a lower state. This approach is typically implemented for fluorescent systems using a special ballast that enables luminaires to be uniformly dimmed in spaces circuited for bilevel switching—as opposed to typical bilevel switching, where alternate lamps or luminaires are turned OFF to achieve the lower state.

Most products are programmed-start T8 ballasts, which may experience a loss of efficacy during light level reduction; dimming to 50%, for example, may reduce wattage by 40%. Instant-start step-dimming ballasts are available that offer proportional reductions in light output and input watts, although instant-start operation is not recommended by some manufacturers for applications with five or more ON/OFF cycles per day. These ballasts can operate without low-voltage wiring. Other hi/lo switching opportunities include corridors that receive a lot of daylight (with a photosensor) and stairwells (with an occupancy sensor).

### 第一步: 调光

步骤调光提供了有限的光级选择，在 OFF 和全输出之间有两个或更多的预置增量。通常情况下，照明状态之间没有淡出，因此，虽然技术上的做法是调暗，视觉效果是灯被切换到一个较低的状态。这种方法通常用于使用特殊镇流器的荧光系统，这种镇流器能够在双层开关的电路中均匀调暗灯具ーー而不是典型的双层开关，即将交替的灯具或灯具关闭以达到较低的状态。

大多数产品是程序启动 T8镇流器，这可能会经历一个失效期间轻水平降低，调光至50% ，例如，可以减少功率40% 。即时启动分步调光镇流器可以提供比例减少光输出和输入瓦，虽然即时启动操作不被一些制造商推荐用于每天有五个或五个以上开/关周期的应用。这些镇流器不需要低压配线就可以工作。其他 hi/lo 转换机会包括接收大量日光的走廊(带有光电传感器)和楼梯间(带有占用传感器)。

### CONTINUOUS DIMMING

Continuous dimming enables users to raise and lower light levels over a specified range, with smooth transitions between levels. This provides a higher degree of flexibility for manual dimming control driven by application needs such as A/V presentation, mood setting and so on. It also enables light output to be automatically reduced to save energy without irritating occupants, and is therefore the control method of choice for automatic control strategies in spaces occupied by people performing stationary tasks.

The rest of this course will focus on continuous dimming.

### 连续调光

连续调光使用户能够在指定范围内提高和降低光线水平，水平之间的平滑过渡。这为手动调光控制提供了更高程度的灵活性，这是由应用需求驱动的，如 A/V 显示、情绪设置等。它也使光输出自动减少，以节省能源，而不会刺激占用者，因此是控制方法的选择，自动控制策略的空间，人们占用执行固定任务。

本课程的其余部分将集中于连续调光。

### LAMPS AND BALLASTS

Most dimmable ballasts are electronic programmed-start ballasts with models available for control of up to 4 linear T8 lamps (including energy-saving lamps), 1 or 2 linear and twin-tube T5 and T5HO lamps, and 1 or 2 four-pin compact fluorescent lamps. T8 lamp types covered by dimmable ballasts include 2-ft. 17W, 3-ft. 25W, 4-ft. 32W (and 23W, 25W, 28W and 30W) and 5-ft. 40W.

Note that some amalgam lamps are dimmable but do not respond instantly to dimming commands.

### 灯具和镇流器

大多数可调光镇流器是电子程控启动镇流器，可控制多达4个线性 T8灯(包括节能灯) ，1或2个线性和双管 T5和 T5HO 灯，以及1或2个四针紧凑型荧光灯。可调光镇流器覆盖的 T8灯种包括2英尺。17W，3英尺。25W，4英尺。32W (及23W、25W、28W 及30W)及5呎。40W.

请注意，有些混合灯是可调光的，但不会立即响应调光指令。

### LAMPS AND BALLASTS

Programmed-start ballasts maintain cathode heating throughout the dimming range while extending service life in frequently switched applications such as occupancy sensor installation. The most efficient dimmable ballasts, identifiable via the NEMA Premium Ballast mark, provide similar wattage as comparable fixed-output instant-start ballasts.

### 灯具和镇流器

程序启动镇流器在整个调光范围内保持阴极加热，同时在频繁切换的应用(如占用传感器安装)中延长使用寿命。最有效的可调光镇流器，可通过 NEMA 高级镇流器标志识别，提供类似的功率作为可比固定输出即时启动镇流器。

### DIMMING RANGE

Dimming is often expressed as a percent. While this may be the fraction of rated power, usually it is an expression of relative light output. For example, a lighting system at 25% dimming range produces 25% of its full light output.

### 调光范围

调光常用百分数来表示。虽然这可能是额定功率的一部分，通常是一个相对光输出的表达式。例如，调光范围为25% 的照明系统产生的光量占其全光输出的25% 。

### DIMMING RANGE

The dimming range expresses how low the ballast can dim the lamps. A lamp with a dimming range of 100% to 5%, for example, can dim from full light output to 5% of full light output. Dimmable T8 ballasts can dim down to as low as 3%, T5HO ballasts as low as 1%, and dimmable CFLs to as low as <3%. A number of factors may affect actual dimming range in a field installation, such as voltage to the ballast, ambient temperature, lamp life used/remaining and lamp seasoning.

### 调光范围

光范围表达如何低镇流器可以调暗灯。例如，调光范围为100% 到5% 的灯，可以从全光输出调暗到全光输出的5% 。可调光 T8镇流器可调光至3% ，T5HO 镇流器可调光至1% ，可调光紧凑型荧光灯可调光至 < 3% 。在现场安装过程中，许多因素会影响实际调光范围，例如镇流器电压、环境温度、灯泡使用/剩余寿命和灯泡调光等。

### DIMMING RANGE

Dimming range is a factor in whether the ballast is categorized as an architectural dimming ballast, which typically dim down to <1%, or energy management dimming ballast, which typically dim down to around 5-10%. Architectural dimming applications are driven by visual needs, such as conference rooms. Energy management applications include daylight harvesting and demand response. An application that intersects these categories is giving office users the ability to dim their overhead lighting.

### 调光范围

调光范围是一个因素，决定了这种镇流器是属于建筑调光镇流器，一般调光到 < 1% ，还是属于能量管理调光镇流器，一般调光到5-10% 左右。架构调光应用程序是由视觉需求驱动的，例如会议室。能源管理应用程序包括日光采集和需求响应。一个与这些类别相交的应用程序可以让办公室用户调暗他们的头顶照明。

### DIMMING METHODS

Dimmable ballasts operate according to a dimming method, which may be analog ("step dimming," 0-10VDC, phase control and wireless infrared) or digital (DALI, proprietary). The three major methods are two-wire (below, left), three-wire (below, middle) and four-wire (below, right). Selection of dimming method is typically based on the use of the space, desired dimming range, wiring, lamp type, physical size and /or budget.

### 调光方法

可调光镇流器按照调光方法运行，可以是模拟(“逐次调光”、0-10VDC、相位控制和无线红外)或数字(DALI，专利)。三种主要的方法是二线制(左下)、三线制(中下)和四线制(右下)。调光方法的选择通常基于空间的使用、所需的调光范围、布线、灯的类型、物理尺寸和/或预算。

### 调光方法:模拟0-10伏直流电

The 0-10VDC ballast features four wires, with two line-voltage leads to power the ballast and two low-voltage control leads to change the light level.

0-10伏直流镇流器的特点是四根电线，两根线电压引线为镇流器供电，两根低压控制引线改变亮度。

The ballast responds to low-voltage control signals transmitted along the communication wires from a compatible control device. When the voltage level is near or above 10V, the ballast responds with full light output. As voltage decreases, the ballast reduces output. These ballasts can dim as low as 3% for T8 lamps and CFLs, and 1% for T5HO lamps.

镇流器响应从兼容的控制设备沿通信线路传输的低压控制信号。当电压水平接近或高于10V时，镇流器以全光输出响应。随着电压降低，镇流器降低输出。对于T8灯和节能灯，这些镇流器的调光率低至3%，对于T5HO灯，调光率低至1%。

### 调光方法:模拟0-10伏直流电

0-10VDC is the most popular type of dimming method for energy management applications. The wiring scheme adds labor and material costs to the installed system cost, but enables the ballast to connect to other ballasts and devices, and multiple lighting circuits can be controlled from a single control location. This type of ballast is compatible with a broad range of control products and manufacturers. Manufacturers of 0-10VDC ballasts include Lutron Electronics (TVE), OSRAM SYLVANIA (Quicktronic Helios and PHO-DIM), Philips Lighting Electronics (Mark 7 0-10), Universal

Lighting Technologies (Ballastar, SuperDim) and others.

0-10VDC是能源管理应用中最流行的调光方法。布线方案增加了安装系统成本中的人工和材料成本，但是使得镇流器能够连接到其他镇流器和设备，并且可以从单个控制位置控制多个照明电路。这种类型的镇流器兼容广泛的控制产品和制造商。0-10VDC镇流器的制造商包括Lutron Electronics (TVE)、OSRAM SYLVANIA(Quicktronic Helios和PHO-DIM)、飞利浦照明电子(Mark 7 0-10)、通用照明技术(镇流、SuperDim)等。

### 调光方法；模拟双线相位控制

Analog two-wire phase control—also called AC dimming, forward phase control, triac dimming, phase-chop dimming and two-wire dimming—uses existing power wiring for control signal communication. The ballast features two line-voltage leads for both power and ballast control, wiring the same way as a conventional fixed-output ballast. These ballasts can dim as low as 5% for T8 lamps and  CFLs, and 1% for T5HO lamps.

模拟双线相位控制——也称为交流调光、正向相位控制、三端双向可控硅开关使用现有的电源线进行控制信号通信。该镇流器具有两个线路电压引脚，用于电源和镇流器控制，布线方式与传统的固定输出镇流器相同。对于T8灯和节能灯，这些镇流器的调光率低至5%，对于T5HO灯，调光率低至1%。

The ballast reads the AC power supply signal's starting (or zero crossing) point and then activates the current after a preset waiting time, cutting out part of the cycle and producing a dimming effect. The waiting time—0 to 8.3 milliseconds or one-half the waveform—is related to the dimming.

镇流器读取交流电源信号的起点(或过零点)，然后在预设的等待时间后激活电流，切断部分周期并产生调光效果。等待时间0至8.3毫秒或波形的一半与变暗有关。

### 调光方法；模拟双线相位控制

Two-wire phase-control ballasts have the advantage of not needing additional wiring between the ballast and control device, making this method particularly suited to retrofits, standalone applications and cost-sensitive projects. Most (if not all) dimming control manufacturers include a way to adjust the dimming curve for their dimming panels to enable control of two-wire ballasts. Additionally, the control signals are less sensitive to interference than low-voltage analog signals. Manufacturers of two-wire phase-control dimmable ballasts include Lu tron (Tu-Wire), OSRAM

SYLVANIA (Power Sense, which is compatible with both two-wire and 0-10VDC dimming controls) and Philips Lighting Electronics (Mark 10Powerline).

双线相位控制镇流器的优点是在镇流器和控制设备之间不需要额外的布线，使得这种方法特别适合于改造、独立应用和成本敏感的项目。大多数(如果不是全部的话)调光控制制造商包括一种方法干扰比低压模拟信号大。双线相位控制可调光镇流器的制造商包括Lutron (Tu-Wire)、OSRAM SYLVANIA (PowerSense，兼容双线和O-10VDC调光控制)和飞利浦照明电子(Mark 10 Powerline)。

### 调光方法；模拟三线相位控制

Three-wire phase control uses a third wire (in addition to hot and neutral) to carry the (typically) phase-control signal to the ballast. All three wires arerated Class 1 and can be run within the same conduit. These ballasts can dim lamps as low as 1%.

三线相位控制使用第三条线(除了火线和零线)将(典型的)相位控制信号传送到镇流器。所有三根电线的等级均为1级，可在同一导管内运行。这些镇流器可以调暗灯低至1%。

### 调光方法；模拟三线相位控制

Typical applications include architectural dimming applications such as conference rooms, boardrooms, patient/exam/treatment rooms, houses of worship, theaters, convention spaces, restaurants, air traffic control centers, partitioned meeting rooms, CAD/CAM workstations, private offices and others. Manufacturers of three-wire phase-control dimming ballasts include Lutron Electronics (Hi-lume, Hi-lume 3D, Compact SE, EcoSystem andECO-10) and Lightolier Controls (PowerSpec HDF).

典型应用包括建筑设计应用，如会议室、会议室、病人/检查/治疗室、礼拜堂、剧院、会议场所、餐厅、空中交通控制中心、分区会议室、计算机辅助设计/计算机辅助制造工作站、私人办公室等。三线相位控制调光镇流器的制造商包括卢特龙电子公司(高亮度、高亮度3D、紧凑型se、生态系统和ECO-10)和照明控制公司(HDF电力公司)。

### 调光方法；模拟无线红外

Wireless infrared dimming utilizes an IR transmitter to perform the control function and does not require additional wires. The dimmer is included either in the ballast or as an additional device in the light fixture. These ballasts can dim lamps as low as 1%.无线红外调光利用红外发射器来执行控制功能，而不需要额外的电线。调光器或者包含在镇流器中，或者作为灯具中的附加设备。这些镇流器可以调暗灯低至1%。

### 调光方法；模拟无线红外

Wireless infrared is highly suitable to spaces where individual fixture control is desired without additional wiring, such as conference rooms, board rooms and open and private offices. This can be a good retrofit solution, and allows for occupant control of their local lighting. Individual fixtures or groups of fixtures can be controlled via a handheld remote control or PDA with a line of sight.

无病毒红外线非常适合需要独立固定装置控制而不需要额外控制的空间布线，如会议室、会议室、办公室和私人办公室。这可能是一个很好的翻新解决方案，并允许居住者控制他们的局部照明。单个固定装置或固定装置组可通过手持遥控器或PDA视线控制。

Wireless infrared is highly suitable to spaces where individual fixture control is desired without additional wiring, such as conference rooms, board rooms and open and private offices. This can be a good retrofit solution, and allows for occupant control of their local lighting. Individual fixtures or groups of fixtures can be controlled via a handheld remote control or PDA with a line of sight. Digital dimming ballasts are 120/277V programmed-start four-wire fluorescent electronic ballasts currently available for control of up to 4 T8 lamps and 1 or 2 CFL or T5/T5HO lamps. The ballast can dim the lamps down to 1%. What sets this type of ballast apart is embedded intelligence and potential for two-way communication.

### 数字调光镇流器

The ballast functions as the controller, potentially eliminating the need for dimming modules and control panels for switching and dimming. The ballast is addressable, making each ballast potentially a separate control zone. Digital communication architectures use soft configuration schemes such as programming, enabling ballasts to be grouped and zoned and rezoned using software, not wiring. The ballast can provide status information that can be used for energy analysis and ongoing maintenance.On the left is a conventional controls wiring scheme. Five separate lead runs from the wall controller are required here, creating complexity. If the system must be changed in the future, wiring is required. On the right is a digital network wiring scheme. All ballasts are connected to the same lead run, simplifying the wiring required. Rezoning and adding controllers is also simplified.

镇流器起到控制器的作用，潜在地消除了对用于开关和调光的调光模块和控制面板的需要。镇流器是可寻址的，使得每个镇流器潜在地成为一个单独的控制区域。数字通信架构使用软件配置方案，例如编程，使得镇流器能够使用软件而不是线路进行分组、分区和重新分区。镇流器可以提供可用于能量分析和持续维护的状态信息。左边是传统的控制接线图。此处需要从墙壁控制器引出五条单独的引线，这造成了复杂性。如果将来必须更换系统，则需要布线。右边是数字网络布线方案。所有镇流器都连接到相同的引线，简化了所需的布线。重新分区和添加控制器也得到简化。

### 数字调光镇流器；协议

The ballasts may communicate with controllers using the Digital Addressable Lighting Interface (DALI) protocol, which offers the possibility of true interchangeability between manufacturers and defines light output for all levels of dimming signals, ensuring consistent dimming performance regardless of type or manufacturer. Some manufacturers offer products that communicate using a proprietary protocol.

镇流器可以使用数字可寻址照明接口(DALI)协议与控制器通信，这提供了制造商之间真正可互换性的可能性，并为所有级别的调光信号定义光输出，确保一致的调光性能，而与类型或制造商无关。一些制造商提供使用专有协议进行通信的产品。
