一款散热设计合理,制做精细的灯具,散热能力和功率有相应的对应关系。散热片的体积、重量决定了热量的储存能力,所以散热片一般都是个大坨坨。散热片的面积决定了最后的散发能力,为了加大面积,一般会做成各种柱、网、片等形状。

A cooling design is reasonable, the system makes fine lamps, cooling capacity and power has a corresponding relationship. The radiator volume, weight determines the heat storage capacity, so the heat sink is usually a big lump. Heat sink area determines the final distribution capacity, in order to increase the size of the general will be made into a variety of columns, mesh, film and other shapes.

散热器在济南广告字 http://www.gift4yu.com/ 的成本里占了很大一块。某些偷工减料的工厂为了节约成本,会以次充好、以小充大。那么问题来了:我们如何判断一个灯具的散热器做得好不好呢?

Radiator in the cost of advertising in Ji'nan accounted for a lot of。 Some factories to cut corners in order to save costs, will be shoddy, to a small charge large。 So the question comes: how do we judge a lamp radiator do well?

当然,最直接的方法是测量济南广告字工作时LED芯片的温度,专业术语叫做“结温”。管他怎么吹,结温控制在可接受的范围内,那就是做得好,反之就是偷工减料了。

但是,结温不是那么容易测量的,需要一连串的专业设备和方法,才能准确测量出灯具内部核心位置LED芯片的结温。有时,即使用专业设备,也只能从外部看到表象,无法深入测量。

However, junction temperature is not so easy to measure, a series of professional equipment and methods, in order to accurately measure the core position of the internal core LED chip junction temperature。 Sometimes, that is, the use of professional equipment, but only from the outside to see the appearance, can not be in-depth measurement
