Flexible LEDs find a foothold in the signage market as fabricators navigate the latest lighting options.

LED逐渐在标识市场找到了一个立足点,成为最热门的标识材料选择。

 

These 20 in. tall reverse channel letters for Eastern Kentucky University’s football program were fabricated by Integrity Sign Solutions (New Albany, IN) and instalLED by Instant Signs (Lexington, KY). The letters are halo-lit with Principal LEDs Qwik Tape technology.

东肯塔基大学足球项目的发光字由新奥尔巴尼的诚信标识制作公司(Integrity Sign Solutions)制作,并由肯塔基州列克星敦的即时标识公司(Instant Signs)安装,这些主LED都是用的Qwik Tape技术进行照明。

 


Richard Holzer, vice president of Xacto Signs , a custom sign wholesaler in Cleveland, remembers first observing LEDs in European airports back in the ’90s. “LEDs came first in Europe, then here [in the US].said Holzer, who is French. “They’ve gotten brighter, and also smaller and smaller.” Within the world of LEDs exist flexible LEDs (meaning LED lamps mounted on a flexible substrate), which encompass myriad products and various interpretations of flexible LED classification. For instance, should flexible LED tubing that functions as neon tube lighting or neon replacement lighting be categorized under flexible LEDs? The answer lies in the eye – or diode – of the beholder, but for our purposes, products such as G2G Lighting’s Aurora Flex and Aurora Flex Mini are included. In addition to neon lighting, flexible LEDs can be sorted into linear border tubing (the LED is encapsulated or embedded inside a silicone or plastic tube) and tape lighting (with a “V” shape essential to its bending properties). Linear border tubing and tape lighting are created with different printed circuit boards (PCBs) and separate manufacturing processes. Possible applications for flexible LEDs range from lighting routed acrylic letters and channel letters (such as halo- or shallow-lit), to edge-lighting signage panels, to cove and display lighting.

克利夫兰定制标识批发商,Xacto标识公司的副总裁理查德·霍尔泽(Richard Holzer)回想起在90年代首次观察欧洲机场的LED,他说:“LED首先出现在欧洲,然后是在美国。它们逐渐变得更亮,也变得越来越小。”在LED的世界中,存在柔性LEDLED灯安装在柔性基板上),其包含无数产品和对柔性LED分类的各种解释。例如,作为霓虹灯管照明的柔性LED灯管是否应归入柔性LED?答案在于旁观者的看法或二极管,但出于我们的目的,包括G2G 照明的Aurora Flex和Aurora Flex Mini等产品。除了霓虹灯照明外,柔性LED还可以分为线性边框管(LED封装或嵌入硅胶或塑料管内)和灯带照明(具有“V”形状,对其弯曲性能至关重要)。使用不同的印刷电路板(PCB)和单独的制造工艺创建线性边框管和磁带照明。柔性LED的可能应用范围从照明布线丙烯酸字母和发光字(例如光晕或浅光),到边缘照明标识面板,到海湾和显示照明。

 

The demand for flexible LEDs is getting bigger and bigger,” Holzer said, adding that most of Xacto’s flexible LED projects involve channel letters and edge lighting. However, the literal size of the projects is decreasing. “These small letters and signs are something that we have to manufacture, and do so competitively,” said Mike Hobbs, co-owner of Integrity Signs Solutions (New Albany, IN), a wholesale sign fabricator. “But that is what defines a good sign fabricator – figuring out how to make it happen.”

霍尔泽说:现在市场对柔性LED的需求越来越大,Xacto的大多数柔性LED项目涉及发光字和边缘照明。然而,项目的文字大小正在发生变化,这些小字体和标识是我们必须制造的东西,而且是有竞争力的。这就考验你是不是一个优秀标识制造者的时候了,你要弄清楚市场流行的走向。

 


Not everyone in the industry is experiencing the same development, which highlights the wide spectrum of projects available in the signage world. “Of all the striping systems, the flexible LED is not utilized quite as much. Not every [lighting] company has it,” said Lenny Diaspro, senior sign territory manager for Graphics Solutions Group (Dallas), a wholesale distributor, though Diaspro did note that the market is still developing and that he found the neon replacement technology attractive. Denny Meyer, general manager of United-Maier Signs (Cincinnati), said he believes the sign industry has embraced flexible LEDs, but that his company simply doesn’t come across the technology very often. “There’s not a lot of applications for the flexible LED in the majority of the work we do,” Meyer said, “but I’m sure there are sign companies that are using the heck out of them.”

并不是行业中的每个人都经历着相同的发展,这彰显了标识世界中项目的广泛性。批发分销商图形解决方案组织(Graphics Solutions Group的高级标识区域经理伦尼•蒂雅丝波(Lenny Diaspro)表示:“在所有的剥离系统中,柔性LED没有得到充分利用。并非每家照明公司都有这种技术。”不过,蒂雅丝波确实指出,市场仍在发展,他发现霓虹灯替代技术颇具吸引力。联合迈耶标识公司(United-Maier Signs)总经理丹尼•迈耶(Denny Meyer)表示,他认为标识行业已经接受了柔性LED,但他的公司很少遇到这种技术。迈耶说:“在我们做的大部分工作中,并没有很多柔性LED的应用,但我肯定有一些标识公司正在使用它们。”

 


DO YOUR HOMEWORK

做好准备

There are a handful of considerations when choosing the right flexible LED for your sign project, and the first of those is heat sinks/heat sinking. Heat sinks refer to the devices within LEDs that absorb and diffuse surplus heat away from the diode, as too much heat equates to lower light output, color alteration and a decline in LED life expectancy. Heat sinking issues can be solved at the production line – the better the manufacturing, the less it becomes a problem.

在为标识项目选择合适的柔性LED时,有一些注意事项,其中第一个是散热器。 散热器是LED内的设备吸收和散发二极管的多余热量的零件,因为过多的热量等同于较低的光输出,这样就会导致颜色的变化和LED寿命的下降。散热问题可以在生产线上解决,LED制造的越好,问题就越少。

 

A common issue with LEDs is hot spots, or areas of uneven brightness within a lit sign. This can cause LEDs to fail, and amplifies the need for proper distribution of the diodes within an LED. Hot spots can be caused by improper LED placement, power supply issues, and even the shape and depth of the sign itself.

LED的常见问题是,内部亮度不均匀的区域可能导致LED发生故障,这就证明了在LED内正确分配二极管的重要性。内部零件的不正确放置,会导致电源问题,甚至标识本身的形状和深度都可能出现差错。

 


Soldering one strip of lamps to another is a divisive subject. Failure to solder increases the risk of moisture damage to LEDs, and improper soldering brings its own risks. An alternative is a pre-made connector, but that avenue is precarious because it requires LED plug-ins on either side, which creates more opportunity for moisture damage. Soldering can be time-intensive and difficult to learn, though. “Some of us remember when we could run down to RadioShack and pick up some craft or hobby electrical things to solder up with a circuit board,” Hobbs said. “Unless you have extra arms to help hold things in place when soldering, this is a very tedious endeavor. And paying two people to stand and solder all day is not cost-effective.”

将一条灯焊接到另一条灯上是一个有争议的话题。焊接失败会增加LED受潮损坏的风险,而焊接不当也会带来风险。另一种选择是预先制作LED的连接器,但这种方法是不稳定的,因为它需要很多的LED插件,这会造成安装过程中更多的损坏。然而,焊接可能需要大量时间,而且很难学。霍布斯说:“我们中的一些人还记得,什么时候我们可以跑到瑞赛电器公司,拿一些手工或业余爱好的电器用品,用电路板来焊接。除非你在焊接时有额外的手臂来帮助固定东西,否则这是一项非常繁琐的工作。
