荧光粉制作济南广告大字的优点

页面更新时间:2015-06-05 11:15 来源:未知 作者:admin 点击:

首先,虽然不使用荧光粉,就能制备出红、黄、绿、蓝、紫等不同颜色的济南广告大字,但由于这些不同颜色LED的发光效率相差很大,采用荧光粉以后,可以利用某些波段LED发光效率高的优点来制备其他波段的LED,以提高该波段的发光效率。例如有些绿色波段的LED效率较低,台湾厂商利用我们提供的荧光粉制备出一种效率较高,被其称为"苹果绿"的LED用于手机背光源,取得了较好的经济效益。

First, although without the use of fluorescent powder, can be prepared in different colors red, yellow, green, blue, purple, and so on the Jinan advertising characters, but due to the different color LED luminous efficiency of the difference is very big, the fluorescent powder, you can use the advantages of some band led luminous efficiency for the preparation of other bands led, in order to improve the luminous efficiency of the band. For example some green band led efficiency is low, Taiwan manufacturers use our fluorescent powder prepared a kind of high efficiency, are referred to as "apple green" led for mobile phone backlight, and achieved good economic benefit.

其次,济南广告大字 http://www.kangmingda.com/ 的发光波长现在还很难精确控制,因而会造成有些波长的LED得不到应用而出现浪费,例如需要制备470nm的LED时,可能制备出来的是从455nm到480nm范围很宽的LED,发光波长在两端的LED只能以较低廉的价格处理掉或者废弃,而采用荧光粉可以将这些所谓的"废品"转化成我们所需要的颜色而得到利用。

Secondly, advertising characters in Jinan emission wavelength now is still difficult to precisely control, which will cause some wavelength led to application and waste, such as the need for preparation of 470 nm LED may prepared is from 455 nm to 480 nm in a wide range of LED, the emission wavelength at both ends of the LED only to lower the price of disposed of or abandoned, and the fluorescent powder can be these so-called "waste" into the color we need and use.

第三,采用荧光粉以后,有些济南广告大字的光色会变得更加柔和或鲜艳,以适应不同的应用需要。当然,荧光粉在济南广告大字上最广泛的应用还是在白光领域,但由于其特殊的优点,在彩色LED中也能得到一定的应用,但荧光粉在彩色LED上的应用还刚刚起步,需要进一步进行深入的研究和开发。

Third, after the use of fluorescent powder and some Jinan advertising characters of light color will become softer or bright, to meet different application needs. , of course, fluorescent powder in Jinan advertising characters on the most widely used or in the field of white light, but because of its special advantages, in the LED color can also get a certain application, but the application of fluorescent powder in the LED color is still in its infancy and need to further in-depth research and development.
