这里’我写了一篇有关《电气发行商(TED)》杂志4月号的LED替换灯的文章,您可能会发现它很有趣:

随着性能的提高和成本的下降,对LED替换灯的需求继续快速增长。根据Navigant Research的研究,到2021年,全球LED灯的出货量将从2013年的6800万增长到近13亿,复合年增长率约为44%。

这些灯可分为全向灯(例如A),定向灯(例如PAR,BR,MR),装饰灯(例如B10,G25)和线性灯(例如T8)。本文将重点介绍全向A灯和定向灯,它们在LED替换灯中的需求方面最受欢迎。能源部(DOE)估计,美国LED A型和定向灯的安装数量从2009年的不到100万个增加到2012年的近2000万个和超过1100万个。

Cree,Inc.照明产品组合经理Jeffrey Hungarter说:“ LED灯的增长已经远远超过了我们在照明行业看到的任何其他技术转型。随着对低效照明的认识不断提高,以及法规的出台,这一趋势将继续下去。逐步淘汰低效照明。”

《能源独立与安全法》导致在2012年至2014年之间逐步淘汰40-100W白炽灯通用照明旋入式灯,行业内提供了多种选择的节能卤素灯,紧凑型荧光灯和LED灯。美国能源部的法规在2012年淘汰了大多数剩余的白炽灯和卤素灯以及反射灯(有些例外),行业提供了红外涂层卤素灯,陶瓷金属卤化物,紧凑型荧光灯和LED灯的选择。

“ LED PAR灯的最佳销售机会是在零售和酒店业应用,”欧司朗SYLVANIA的市场经理Cheryl Ford说。 “最大的A灯安装基地是在家庭中,但酒店将在酒店房间和大厅安装LED灯,从而大大节省能源和维护费用,从而从中受益匪浅。”

与白炽灯和卤素灯光源相比,LED灯具有几个显着的优点,包括节省多达85%的能源以及25,000至50,000小时的长期使用寿命。它们不含汞。由于它们没有灯丝,因此可以抵抗因震动和振动而引起的光源故障。并且发光几乎不包含热量和紫外线输出。大量的节能,改进的性能以及对该技术的更大信心,导致公用事业折扣计划迅速采用了LED灯。根据BriteSwitch,LLC的数据,2013年底,LED替换灯的平均回扣约为12美元。尽管总体资金在增加,但每种产品的平均回扣正在下降,这反映了产品成本的下降。例如,几年前刚花费60美元的LED A灯最近突破了10美元的价格壁垒。

根据《照明事实》数据库的最新DOE关于A灯的DOE快照报告发现,现在注册灯的平均功效为69流明/瓦(变化范围很大)。 <60 to nearly 90 lumens/W, so scrutinize products carefully), surpassing the average 60 lumens/W for compact fluorescent lamps. Ninety-five percent of these lamps satisfy current ENERGY STAR efficacy criteria, while nearly 90 percent meet new ENERGY STAR criteria set to take effect in September 2014. Several LED A-lamps are now available offering light output equivalent to 75W and 100W incandescents. Most have a warm color temperature of 2700K or 3000K, similar to incandescent, with a color rendering index (CRI) rating in the 80s. LED technology is also suited to other capabilities related to accompanying advances in digital control technology. For example, the lamp may be programmed to become warmer in color tone as it is dimmed, matching what consumers expect from incandescent lamps. As another example, wireless control built into the lamp enables lamps to be remote controlled from a smart device, including ON/OFF, raise/lower and color tuning. “New LED lamps with ZigBee wireless control incorporated into the lamp design for use with home automation systems eliminates the dimmer incompatibility issues with no limitations on the number of lamps on a circuit,” says Ford. “This wireless technology allows for controlling the lamps wirelessly via a smart device that communicates directly with the home automation hub.” LED lamps continue to pose some performance issues, however. These include issues with dimming compatibility and lower color quality than incandescent. “LED offers vastly better efficiency than halogen or incandescent and much longer life, but has traditionally required a step back in light quality and dimmability, and cannot be used in enclosed fixtures in most cases,” says Susan Larson, vice president of sales-Americas for Soraa. “Most LED lamps offer a CRI similar to compact fluorescent lamps (80) and are friendlier to operate with dimmers, yet their quality is not as good as incandescent or halogen.” She points out that the best products on the market address these issues, while advising distributors to ensure compatibility between a given lamp and enclosed fixtures, dimmers, transformers and controls prior to purchase and installation.

谢丽尔·福特(Cheryl Ford)补充说,在选择产品时,分销商应注意R9,它描述了除了CRI和色温以外,灯呈现红色的程度。她指出,即使是这些指标也不能总是最佳地表征给定应用中的灯的颜色质量,并建议安装样品以进行适当的评估。

“我们建议电力分销商做好功课,” Hungarter说。 “仅仅LED灯可以节省能源并延长使用寿命,并不意味着它最适合您的应用。还需要考虑其他产品功能,例如灯的美感,光束功率和分配,LM79测试,调光兼容性以及符合ENERGY STAR。只有通过针对这些特性中的每一个评估LED替换灯,您才能确定哪种LED灯最适合您的应用。”

“指标很重要,但灯泡最重要的测试是人们如何看待它的光线,”拉森说。 “大多数人无需详细了解基本指标就可以立即看到不良照明与良好照明之间的区别,因此定性判断通常会推动设计决策,其作用远超出通常的认识。我们的建议是仅在灯光或皮肤外观下查看自己的镜像,您将能够选择适合您的灯。”

The California Energy Commission (CEC) recently published a voluntary specification for LED replacement lamps that goes beyond ENERGY STAR by being more aggressive in terms of lighting quality. For example, the CEC spec requires the lamp to have a 90+ CRI with an R9>50. All lamps must be capable of continuous dimming to 10 percent of light output without flicker. While the spec is voluntary, CEC required the state’s utilities to recognize only compliant products in their residential rebate programs, which was expected to go into full effect in early 2014. A few products currently comply, such as some SYLVANIA ULTRA PRO LED lamps, Cree’s LED TW Series and Soraa’s Vivid LED MR16.

亨格特说:“掌握一点知识会大有帮助。” “如果您可以自信地说出在现有技术上选择特定的LED灯,那么客户将倾听并可能根据您作为LED顾问的建议进行切换。”
