浅谈LED功率的使用要求

A Study on the Use of LED Power Requirements

目前LED已经在照明市场上占据了相当的份额。今后将有更多的LED应用产品问世。因此,我们对LED产品的功率使用也提出了更多的要求和限制。LED功率在实际应用和实验室测量有许多差异。这为设计LED应用产品带来了困难。根据实际使用情况,本文分析了影响LED功率的几个因素,如光效、温度、驱动电流,并介绍了过耗使用和低耗使用LED的例子。对于今后LED应用产品的设计思路,文中简单地介绍了易耗型、高稳定型和功能型LED产品的特点和应用领域,并就设计LED应用产品时应考量的几个综合成本因素作了一定的讨论。

Now, LED lighting has occupied a considerable market. In the future, there will be more LED applications available, Therefore, more and more demands and constraints of the LED product＇s power are made, LED power has many differences between the practical application and laboratory measurements, It brought difficulties for the design of LED products, According to actual use, this article analyzed the impact factors of the power LED, such as luminous efficiency, temperature, current. It also introduced the example of overload and low load of LED products, To the design of LED applications, this article briefly introduced the Consumable type, stability type and function type of LED product, and their features, applications, It discuss es how to consider about several factors integrated in the design of LED applications,
