## LED DRIVERS AND POWER SUPPLIES

Most LED products require devices to condition incoming power and control the energy flow passing through the LEDs within, including converting incoming power from AC to DC. LED drivers control power flowing through the LED product by either maintaining a constant voltage or constant current. Power supplies may be integrated into the driver or mounted separately.

As there are no special demands made by LED products that require special switching control, switching and relay-based control of LEDs can be effected the same as with fluorescent loads.

For dimming, it is important to note that not all LED products can be dimmed. Special LED drivers and power supplies are required; the product must be rated as dimmable.

There are several methods for achieving dimming, including phase cut power line side control, separate line voltage control and low voltage control in either analog or digital forms. Achieving satisfactory results requires matching the type of control with the driver and/or power supply components.

LED驱动器和电源

大多数LED产品都要求设备调节输入电源并控制流经LED内部的能量流，包括将输入电源从交流电转换为直流电。LED驱动器通过保持恒定电压或恒流来控制流经LED产品的功率。电源可以集成到驱动器中或单独安装。

由于LED产品没有特殊的要求，需要特殊的开关控制，LED的开关和基于继电器的控制可以起到与荧光负载相同的作用。

对于调光，重要的是要注意不是所有的LED产品都可以调光。需要特殊的LED驱动和电源;产品必须是可调光的。

## 2-WIRE LINE-VOLTAGE DIMMING

The simplest control system is 2-wire line-voltage dimming. This refers to any control placed on the power line feeding an LED product, usually 120V AC. Products designed for line-voltage control use either standard wall-box dimmers or remote dimmer modules designed for line-voltage incandescent, magnetic and electronic low-voltage incandescent, or line-voltage dimmable fluorescent loads. Due to large variations in dimmer characteristics and LED driver system designs, compatibility of line-voltage controls and driver system are not universally assured.

电线电压调光

最简单的控制系统是两线线电压调光。线电压控制产品使用标准壁箱调光器或为线电压白炽灯、磁性和电子低压白炽灯或线电压可调荧光负载设计的远程调光器模块。由于调光器特性和LED驱动系统设计的巨大变化，线路电压控制和驱动系统的兼容性并不能得到普遍的保证。

## PHASE-CUT TRIAC (FORWARD OR LEADING EDGE) DIMMING

Wall-box dimmers control current flow to connected loads by modifying the sine wave using one of two approaches. The most common incandescent

dimmer design is called a triode for alternate current, or TRIAC, design. This is simple low-cost design that switches power OFF at the leading edge of the sine wave for a period of time and then switches it back ON, producing a sudden voltage jump from zero to whatever the line voltage is at the end of the dim cycle time.

This abrupt change, and switching the load ON and OFF, will disrupt the proper operation of LED driver and power supplies not designed to function on TRIAC-dimmed circuits.

SE-CUT三端双向可控硅开关(前向或前缘)变光

壁盒调光器通过使用两种方法之一修改正弦波来控制电流流向连接负载。最常见的白炽灯设计称为交流电三极管，或TRIAC设计。这是一种简单的低成本设计，它在正弦波前端关闭电源一段时间，然后再打开电源，在昏暗周期结束时，产生一个突然的电压跃变，从零跳到线路电压所在的位置。

这种突然的变化，以及负载的开关，将会破坏LED驱动器和电源的正常运行，而这些电源不是设计用于三通调暗电路的。

## PHASE-CUT MOSFET (TRAILING EDGE) DIMMING

Through use of specialized transistors and small logic processors, trailing-edge dimmers maintain the leading edge of the sine wave, ramping voltage up from zero and eliminating the abrupt surges that occur with TRIAC-based dimming. This circuit design was developed to control electronic loads, improving power supply performance and reducing electromagnetic interference (EMI).

Using these dimmers to control LED systems, however, requires special circuiting within the LED power supply and/or driver to accommodate input power fluctuations.

舍相MOSFET(后缘)调光

通过使用专门的晶体管和小型逻辑处理器，后缘调光器保持正弦波的前沿，将电压从零调高，并消除基于三极管的调光所产生的突然波动。这种电路设计是为了控制电子负载，提高电源性能和减少电磁干扰(EMI)。

然而，使用这些调光器来控制LED系统，需要在LED电源和/或驱动中使用特殊的电路来适应输入功率的波动。

## UNIVERSAL WALLBOX AND PORTABLE DIMMER CONTROLS

To address some of the issues of retrofit lamps and mixed sources in spaces requiring dimming, new generations of dimmers have been introduced.

These dimmers are designed to operate dimmable compact fluorescent and LED products as well as halogen and incandescent. Specialized circuitry and filtering inside these dimmers produce better control operation and fewer EMI issues.

通用暗线箱和便携式调光器控制

为了解决在需要调光的空间中改装灯具和混合光源的一些问题，新一代的调光器已经被引入。这些调光器被设计用于可调光的紧凑型荧光灯和LED产品以及卤素灯和白炽灯。专门的电路和过滤内部这些调光器产生更好的控制操作和较少的电磁干扰问题。

## RETROFIT LED PRODUCTS WITH INTEGRATED DRIVER CIRCUITS

LED retrofit lamps that operate on standard dimmers are an excellent upgrade to bring the energy savings of LEDs into lighting systems with existing controls. In applications with existing dimmers, look for compatible retrofit products designed to operate with them. These products use special circuitry to maintain proper function with dimmers. Note, however, that not all

lamps designed to operate on conventional dimmers will work with all dimmer products. To ensure the controls in use and the selected retrofit lamp are compatible, consult the manufacturers.

用集成驱动电路改造LED产品

使用标准调光器的LED改造灯具是一种极好的升级，可以将LED的节能效果带入现有的照明系统中。在现有调光器的应用中，寻找与之兼容的改造产品。这些产品使用特殊的电路与调光器保持正常的功能。但是，请注意，并不是所有设计用于操作传统调光器的灯具都适用于所有调光器产品。为了确保所使用的控制和所选的改装灯是兼容的，请咨询制造商。

## STANDARDIZATION OF FORWARD PHASE-CUT DIMMING

NEMA’s standard, SSL 7A-2013, Phase-Cut Dimming for Solid-State Lighting: Basic Compatibility, was developed to address compatibility between lamps, luminaires and forward phase-cut wallbox dimming controls.

Products labeled as 7A or SSL 7A compliant are intended to be universally compatible. Zhaga specifications incorporate SSL 7A.

正向相位消减调光的标准化

NEMA标准，ssl7a -2013，固态相切调光

照明:基本兼容性，是为了解决灯具、灯具和正向相位切割墙盒调光控制之间的兼容性而开发的。标为7A或符合SSL 7A的产品旨在实现普遍兼容。Zhaga规范包含了SSL 7A。

## AUTOMATIC CONTROL

The majority of energy-saving applications for lighting control involves use of automatic lighting controls. LEDs are not adversely affected by frequent switching or dimmed operation. In applications where line-voltage control is used, there is nothing inherent to LED lighting that precludes it being controlled in the same manner as any other light source.

Occupancy sensors, photocontrols, remote switching and connection to building power management systems remain very similar to fluorescent or incandescent controls.

自动控制

大多数照明控制的节能应用涉及自动照明控制的使用。led不受频繁切换或昏暗操作的不利影响。在使用线电压控制的应用中，没有任何固有的LED照明妨碍它被以与任何其他光源相同的方式控制。居住传感器、光电控制、远程开关和连接到建筑电源管理系统仍然非常类似荧光或白炽灯控制。

## CONTROL METHODS AND PROTOCOLS: 3-WIRE LINE-VOLTAGE DIMMING

Three-wire line-voltage dimming, developed for fluorescent dimming, involves a third line-voltage dimmed control wire. Products designed for 3-wire line-voltage control use either wallbox dimmers or remote dimmer modules. Since power supplied to the LED driver is maintained at full power, with control signal provided separately, issues of dimming range and product compatibility are significantly reduced over simple line-voltage wallbox dimming controls.

控制方法和协议:三线线电压调光

三线线电压调光，为荧光调光开发，涉及第三线电压调光控制线。产品设计为三线线电压控制使用壁盒调光器或远程调光模块。由于LED驱动器的电源保持在全功率，控制信号单独提供，通过简单的线电压墙盒调光控制，调光范围和产品兼容性问题显著降低。

## CONTROL METHODS AND PROTOCOLS: 0-10V

0-10V control establishes a consistent Class 2 wiring interface that is light source agnostic. All connected luminaires include a logic circuit that interprets their total dimming range from lowest to highest, within the common range of 0V to 10V. For LED systems that incorporate power supplies and drivers to maintain constant current or constant voltage to the LED sources, the use of 0-10V control is the most universally available dimming capability. This allows the use of the already well established system components used for fluorescent lighting, and is fully compatible in mixed source applications. The only requirement is to utilize a separate control for each luminaire type, never mixing sources on one control. This applies to mixing LED products as well as mixing LEDs with other sources.

控制方法和协议:0-10V

0-10V控制建立一致的2类接线接口，不受光源影响。所有连接的灯具都包含一个逻辑电路来解释其亮度范围从低到高，在0V到10V的共同范围内。对于包含电源和驱动器以保持LED光源恒流或恒压的LED系统，使用0-10V控制是最普遍可用的调光能力。这允许使用已经建立良好的系统组件用于荧光灯，并完全兼容的混合源应用。唯一的要求是对每种灯具类型使用单独的控制，不要在一个控制上混合光源。这适用于LED产品的混合以及LED与其他光源的混合。

## CONTROL METHODS AND PROTOCOLS: PHOTOSENSOR 0-10V DIMMING CONTROL

This type of control provides proportional luminaire output based on the input or received ambient light from a 0-10V sensor. The chart below depicts the linear characteristics from a 0-10V photosensor that is linked to an LED dimming driver. A typical 0-10V sensor will need to be connected or linked to a controller that will convert the sensor output into the appropriate driver voltage via the control algorithm.

控制方法和协议:光传感器0-10V调光控制

这种类型的控制提供的比例灯具输出基于输入或接收环境光从0-10V传感器。下面的图表描述了与LED调光驱动器相连的0-10V光敏传感器的线性特性。一个典型的0-10V传感器将需要连接或连接到控制器，通过控制算法将传感器输出转换为适当的驱动电压

## CONTROL METHODS AND PROTOCOLS: PHOTOSENSOR 0-10v SWITCHING CONTROL

A typical 0-10V or 1-10V photosensor can also be connected to a controller that has been programmed to provide daylight ON/OFF switching control as depicted in the graphic below.

## CONTROL METHODS AND PROTOCOLS: DMX

DMX512A is based on a Class 2 RS485 serial bus that uses XLR Style 5 pin connectors (basic F+DMX requires only three of these) or Cat 5 Ethernet cabling with 8P8C connectors (similar to RJ45). The bus speed is relatively slow at a rate of 250 kbaud. Luminaires are connected in a series daisy chain with a termination resistor installed on the last luminaire.

Each connected luminaire is assigned a unique three-digit address either by 1) software based on location in the daisy chain, DIP switches or dials in the luminaire, or 2) an electronic addressing module in the luminaire or in the system. The software will allow grouping to respond to identical settings. While no two luminaires share the same address, they may be grouped as a single load outside the DMX universe and assigned to a dimmer that is part of it.

控制方法和协议:DMX

DMX512A是基于一个类2 RS485串行总线使用XLR风格5

pin连接器(基本的F+DMX只需要其中的三个)或使用8P8C连接器(类似于RJ45)的Cat 5以太网电缆。公共汽车的速度是相对较慢，速率为250kbaud。灯具以串联菊花链连接，终端电阻安装在最后一盏灯具上。

根据菊花链、DIP开关或刻度盘的位置，软件会给每个连接的灯具分配一个唯一的三位数地址灯具，或2)灯具或系统中的电子寻址模块。该软件将允许分组响应相同设置。虽然没有两个灯具共享相同的地址，他们可以作为一个单独的负载在DMX宇宙和分配给a那是它的一部分。

## CONTROL METHODS AND PROTOCOLS: RS485

RS485 is a standard for balanced data multipoint communications, commonly

accomplished over three-, four- or five-wire cabling systems. The most common is used with the DMX512A controls protocol. Standard pin-out connections assure installations comprised of several manufacturers’ products remain compatible.

控制方法与协议:RS485

RS485通常是平衡数据多点通信的标准可完成三线、四线或五线布线系统。最常见的是与DMX512A控件协议一起使用。标准线图连接确保由几个制造商的产品组成的安装保持兼容。

## CONTROL METHODS AND PROTOCOLS: ART-NET

Art-Net, a trademark of Artistic License Holdings, Ltd., is an open source protocol based on TCP/IP that allows transfer of large amounts of DMX512 data over wide-area wireless networks. The protocol uses universal addressing and supports more than 4,000 universes when operated on 1000BaseT Unicast networks or 40 universes on broadcast networks.

控制方法和协议:ART-NET

Art-Net是art License Holdings, Ltd.的商标，是一个基于TCP/IP的开源协议，允许大量DMX512的传输，通过广域无线网络传输数据。该协议使用通用寻址，并在运行时支持超过4000个宇宙1000BaseT单播网络或40个宇宙广播网络。

## CONTROLS PROTOCOLS: SMART CONTROL TECHNOLOGIES

The term “Smart Control” applies to a growing range of lighting or whole-building controls approaches that include two-way communications, a network of controlled loads (lighting and other building systems), and various input components, such as sensors, time-clocks, user-activated controls and system feedback loops from loads and power sources. All of the system components are connected through a computerized interface that monitors input channels and feedback from active systems, to control loads to achieve a desired end result.

Smart controls may be wired system based, wireless or a combination of both. While there are no specific limits on how a smart controls system is built, the common requirement is that all components be compatible to one another in order to facilitate the necessary uniform level of control and intelligence processing.

控制协议:智能控制技术

“智能控制”一词适用于越来越多的照明或整栋建筑的控制方法，包括双向通信、智能控制和智能控制控制负载(照明和其他建筑系统)的网络，以及各种输入组件，如传感器、时钟、用户激活控制负载和电源的系统反馈循环。所有的系统组件通过一个计算机化的接口连接监控输入通道和主动系统的反馈，控制负载以达到预期的最终结果。

智能控制可能是有线系统，无线或两者的结合。而对于智能控制系统的性能并没有具体的限制在构建过程中，常见的需求是所有组件相互兼容，以促进必要的统一级别的控制和情报处理.

## CONTROL METHODS AND PROTOCOLS: DALI

The Digital Addressable Lighting Interface, or DALI, is a standard lighting control protocol. As with DMX, each luminaire is assigned a unique address and responds to data signals distributed through a common communication line. DALI further offers two-way communication capability, enabling control systems to feed energy and maintenance information to a centralized point for analysis. Controls may be added anywhere along the low voltage communication bus.

控制方法和协议:DALI

数字可寻址照明接口，或DALI，是一个标准的照明控制协议。与DMX一样，每个灯具都被分配一个唯一的地址和响应通过公共通信线路分布的数据信号。达利进一步提供了双向通信能力，启用控制系统提供能源和维护信息到一个集中的点进行分析。Controls 沿着 lowvoltage 沟通 bus. 可以添加在任何地方

## LOW-VOLTAGE LED CONTROL CONNECTION POINTS

The control wiring may not be to the luminaire location. In many cases, LED products utilize remote power supplies and power supply/driver combinations. In every case, wiring of the control will always be to where the driver electronics are located.

低压LED控制连接点

控制接线可能不在灯具位置。在很多情况下，LED产品使用远程电源和电源/驱动

组合。在每一种情况下，控制线路将始终是司机电子设备的位置。

## AUTOMATIC WHITE LIGHT COLOR SHIFT: DIM TO WARM

LEDs do not shift in color to a warmer color when dimmed like incandescent lamps. For applications where the this effect is desirable to support a desired mood, without adding the complexity of color mixing controls, a growing number of LED products are becoming available to deliver this effect automatically in response to dimmer setting.

自动白光颜色转换:暗淡到温暖

当led像白炽灯一样变暗时，它的颜色不会变暖灯。对于应用程序来说，这种效果是希望支持一个理想的情绪，不添加复杂的颜色混合控件，一个成长越来越多的LED产品可以在调光器设置时自动提供这种效果。

这种从暗到暖的效果是通过混合不同的LED光源来实现的，由内部驱动程序来提供一个温暖的色调光的输出减少了。

## AUTOMATIC LUMEN MAINTENANCE CONTROL

In a conventional lighting system, light loss factors, including lumen depreciation, are added to the desired maintained light level. This results in initial over-lighting that slowly declines to the target illuminance level as the system ages. The result is wasted energy and continually declining illuminance levels.

By starting a system at a reduced energy level, then ramping up drive current over time using automatic or pre-programmed regulation that increases power to the LEDs as the system ages, constant light output is maintained over most of the life of the LED product. Additionally, energy is saved and service life is extended.

Outward appearance and photometric performance of luminaires featuring lumen management control is unchanged.

自动流明维护控制

在传统照明系统中，光损失因素，包括流明贬值，是增加到所需的保持光水平。这导致在最初的过度照明，慢慢下降到目标照度水平，随着系统老化。其结果是浪费能源和持续下降的照度水平。

通过降低能量水平启动系统，然后通过自动或预编程调节，随着系统老化增加LED的功率，随着时间的推移增加驱动电流，在LED产品的大部分寿命中保持恒定的光输出。节省能源，延长使用寿命

具有流明管理控制的灯具外观和光度性能不变。

## ETHERNET POWER AND CONTROL BACKBONE: REDWOOD SYSTEMS APPROACH

Redwood Systems is a unique platform based on line-voltage conversion to constant-current low-voltage DC at a central location, similar to the layout of a computer network server room. Luminaires, sensors and controls are connected to the power supply/driver engines using standard Cat5e cabling. The application network is open, enabling customers and system partners to integrate Application Programming Interface (API) and BACnet/IP protocols. The system is modular, with each central engine capable of powering 64 channels at 500mA, 20W per channel, 12-55VDC.

Luminaires produced with the appropriate RJ45 cable connectors and configured for connection to the Redwood Systems infrastructure are labeled as “Redwood Ready.” Note that these RJ45 connected devices are not compatible in any way with DMX 512A products using the same connectors

以太网电源和控制中枢:红木系统方法

红木系统是一个独特的平台，基于线路电压转换为恒流低压直流在一个中心位置，类似于一个计算机网络服务器室的布局。灯具、传感器和控制器通过标准的Cat5e电缆连接到电源/驱动引擎上。应用程序网络是开放的，使客户和系统合作伙伴能够集成应用程序编程接口(API)和BACnet/IP协议。该系统是模块化的，每个中央引擎能够在500mA, 20W每个通道，12-55VDC功率64通道。

用适当的RJ45电缆连接器生产并配置为连接到Redwood系统基础设施的灯具被标记为“Redwood Ready”。请注意，这些RJ45连接的设备与使用相同连接器的DMX 512A产品在任何方面都不兼容

## CONTROL METHODS AND PROTOCOLS: BACNET

The Building Automation and Control Network (BACnet) is an open whole-building “smart” automation communication protocol developed by ASHRAE. BACnet devices send and receive service messages that can be communicated over wired Ethernet, ARCNET and MS/TOP (masterslave/token passing) LAN networks. BACnet can also include wireless connections by pairing it to other protocols such as ZigBee. BACnet addresses building automation as a whole, encompassing lighting within a larger envelope of control needs including HVAC, security and building utility operations.
