LED照明替换所有低效光源

半导体

到目前为止，我们大多数人已经看到或听说过正在进行的“照明革命”。
您可能已经在电视或报纸广告上看到了无处不在的商业广告，或者您已经走过当地家得宝/宜家/沃尔玛的LED灯具过道。
这是从100年历史的白炽灯泡（技术上，134年）转变为世界上主要的光源之一到更高效的技术的一部分。
这种转变为半导体行业带来了重大的新机遇。
使用LED作为光源的固态照明设备的出现在2009年左右开始广泛接受，推出了基于LED的灯泡，其使用的能量低得多，持续时间比白炽灯泡长得多。
然而，由于它们还要花费更多，直到2013年LED灯泡才开始获得市场份额。
这也恰好与全球许多国家开始实施的白炽灯禁令同时发生。
LED灯泡从***那里获得的自上而下的推动力主要归功于通过改用新技术实现节能。
由于照明约占世界总电力消耗的五分之一，许多国家将此视为大幅减少对化石燃料依赖的机会。
如今，一个主要制造商的LED灯泡相当于广泛使用的60W白炽灯，可以以9美元的价格购买。
这个灯泡仅消耗功率的六分之一，持续约23年，相比传统白炽灯泡只有一年（它实际上是关于总小时数 - 转换为假设每天使用一定的时间段），同时发射相同的灯泡
光输出量。
这是照明技术的一项重大成就，并预测2014年全球将有10亿盏灯具出货。
虽然这种早期增长完全取决于可能实现的节能 - 这是非常重要的 - 但我们认为，这种技术的更新和更多用途将有助于在全球范围内实现更多的渗透。
飞利浦Hue系统就是这种技术的一种新用法。
在它推出之前，灯光真的打开和关闭。
通过新系统，人们现在可以通过智能手机控制发出1600万种色调中的一种。
它们可以编程，以反映一天中的时间，外面的天气，或脉动到你最喜欢的音乐，以模仿舞池迪斯科灯光！
看看这里：
这一切只是一个开始。
是的，对于三个灯泡来说，这仍然是200美元的新奇产品。
但同时请记住，在2012年，现在以9美元的价格出售的同一个LED灯泡的成本将超过40美元。
通过技术的改进 - 即每瓦LED的流明 - 以及半导体技术可能实现的制造进步和效率，实现了价格点的显着降低。
采用LED为所有半导体公司提供了大量机会。
安森美半导体已广泛投资该领域，并为电源管理，传感器，有线和无线连接以及分立半导体提供广泛的解决方案。
现在，如果我们能让更多的人出去用LED灯泡替换所有低效光源！
我们很想听听您对此的看法。
为什么以及在什么价位上你会考虑购买LED灯？

By now, most of us have seen or heard about the “Lighting Revolution” underway.  You’ve likely seen the ubiquitous commercials on TV or the newspaper ads or you’ve walked past the aisles of LED lamps at your local Home Depot/IKEA/Wal-Mart.
This is all part of the shift from the 100-year old incandescent light bulb (technically, 134 years old) as one of the main sources of light across the world to a more efficient technology.  This shift presents a significant new opportunity to the semiconductor industry.  The advent of Solid State Lighting devices using LEDs as the light source started to gain broad acceptance around 2009 with the introduction of LED based bulbs that used much lower energy and lasted significantly longer than incandescent bulbs.  However, since they also cost a lot more, it was not until 2013 that LED bulbs started to gain market share. This also happened to coincide with the ban on incandescent lamps that many countries across the globe began to implement.  This top-down boost that LED bulbs received from governments was primarily due to the energy savings possible by switching to the new technology.  Since lighting accounts for approximately one fifth of the total electricity consumption in the world, many countries saw this as an opportunity to significantly reduce dependence on fossil fuels.
Today, an LED bulb from a major manufacturer that is equivalent to the widely used 60W incandescent can be purchased for ~$9.  This bulb only consumes a sixth of the power and lasts around 23 years, compared to only one year for a traditional incandescent bulb (It’s really about the total number of hours – translated into a period assuming a certain usage per day) while emitting the same amount of light output.  This is a major achievement for lighting technology and has led to forecasts of a billion lamps shipping world-wide in 2014.
While this early growth is all about the energy savings that are possible – which are quite significant – it is our view that there will be newer and more uses of this technology that will contribute to even more penetration across the world.  One such new usage of this technology is the Philips Hue System.  Until its introduction, lights were really turned on and off.  With the new system, one can now control – via a smart phone – lamps to emit one of 16 million shades of color. And they can be programmed to reflect the time of day, the weather outside, or pulsate to your favorite music to mimic disco lights from the dance floor!  Check it out here:

All this is just the beginning. Yes, this is still likely a novelty item at $200 for three bulbs. But also keep in mind that in 2012, the same LED bulb that is now selling for $9 would have cost north of $40. This dramatic reduction in the price point was achieved both from improvements in the technology – i.e., Lumens per watt of LEDs – as well as manufacturing advances and efficiencies that are possible with semiconductor based technology.
The adoption of LEDs opens up a large opportunity for all Semiconductor companies.  ON Semiconductor has invested in this area quite extensively and offers a broad array of solutions for power management, sensors, wired and wireless connectivity along with discrete semiconductors. Now, if only we can get more of you to go out and replace all your inefficient light sources with LED bulbs!
We would love to hear your view of this. Why and at what price point would YOU consider buying LED Lamps?
