行业LED驱动器可靠性低下的原因主要有以下几点：
The reasons for the low reliability of the industry LED drives are the following:
榜首、挨近热源。
The top, near the heat source.
led尽管发光功率较高，但流过LED的能量仍只要小部分能量能够见光的形式辐射出去，其他大多数能量以热的形式耗费在LED中，因而LED光源本身发热比较严重。LED驱动器一般放置在灯具内部，挨近LED光源，在大环境温度只要20-30℃的常温下，驱动器周围的环境温度就很简单到达50-60℃，在如此高的环温下要保证驱动器的可靠性，对规划（尤其是功率指标）具有很大的挑战性。
Led although the luminous power is higher, but the energy flowing through the LED still as long as the radiation in the form of small part of energy can see the light out, most of the other in the form of heat energy consumption in LED, so the LED light source is more serious fever. The LED drive is usually placed on the inside of the light fixture, near the LED light source, at ambient temperature as long as 20-30 DEG C under normal temperature, drive the ambient temperature is very simple at 50-60 DEG C, in such a high temperature to ensure the reliability of the driver, the planning (especially power index) is a great challenge.
第二、长期满负荷作业。
Second, long-term full load operation.
在不调光的情况下LED驱动器即是挨近满负荷作业，而在开关电源的绝大多数应用领域，如计算机电源（适配器）、通讯电源、家用电器等，长期作业的平均功率一般只要额定功率功率几分之一，一切负载都敞开的满功率状况只在特定的少数时间内会出现。
In the case of LED dimming driver is close to full load operation, and in most applications such as switching power supply, computer power supply (adapter), communication power supply and electrical household appliances, the long-term average of the power operation in general as long as a fraction of rated power power, all loads are open full power status will appear in a few hours in particular.
第三、对于路途、广场等室外照明场合，简单遭受外界雷击等自然现象损坏。这些都将会对LED半导体照明的大规模应用造成后期维护等系列弊端。
Third, for roads, squares and other outdoor lighting occasions, simply suffer from natural phenomena such as lightning damage. These will be on the LED semiconductor lighting large-scale applications caused by late maintenance and other drawbacks.
LED驱动电源的高可靠性是LED产品质量的重要条件，一起也是亟待攻破的技能难题。
LED drive power supply reliability is an important condition for the quality of LED products, is also an urgent need to break the technical problems.
