电致发光片(EL)特性

◆ EL 发光片独特的构造和特性使它能为您提供一种其它光源无法相比的特殊平面薄膜冷光源。其原理是通过交流电场激发荧光物质，发出高效率的冷光。　

◆ 很薄 - 最薄可达 0.2mm ，可以利用尽可能小的空间进行发光。　

◆ 能弯曲发光以适应产品的形状，比其他任何人造光源更柔韧。

◆ 有很好的防震性。与其他发光器件不同， EL 发光片不易因受到外界的严重冲击而失效。

◆ 功耗低。即使在电量很低时也易于实现。所以，当功耗成为一个重要因素时，电致发光片就成为理想的选择。

◆ 发光柔和、稳定，不闪烁。即使直视发光片也不会像其它光源那样刺眼，使眼睛产生疲劳感。

◆ 是一种冷光源。工作时无温升。因而可以避免由于热量积累而导致的一系列问题。

The art of watch "dressing" is of vital replica watches importance for obvious reasons... the watch must be adorned with some of the finest jewels in existence and attention must be paid to the slightest detail. fake watches As every Piaget watch is unique in its 18-carat gold or platinum coat and all watches are crafted by hand it is important to Piaget to employ some of the most exceptional crafts-people in the industry. Piaget has found means of balancing its worldwide distribution by pursuing two distinct yet complementary goals: on the one hand, highly selective distribution in accordance with its own demanding quality criteria;tag heuer and, rolex on the other,breitling a limited number of strategically located boutiques under its own name, superb showcases for effectively projecting the Piaget image.fake watch From the beginning, cartier Piaget chose to deal with the world's most prestigious watch making and jewellery sales outlets, fake watches with a view to building a genuine partnership based upon mutual respect and recognition.
