What are the reasons for low reliability of driver of high power LED light and other LED lights of LED industry
Although luminous efficiency of LED light especially high power LED light including high power LED flood light is higher , but just a small part of electricity flowing through the LED can be radiated in the form of visible light energy , most of the remaining energy is consumed in the form of heat in the LED , the LED light source particularly high power LED flood light and other power LED light has serious fever . there are following reasons for low reliability of driver of high power LED light and other power LED lights of LED industry:
First, close to a heat source.
LED drivers are usually placed inside the high power LED flood light and other LED packing light , which is close to the LED light source, the ambient temperature around the driver can easily reach 50-60 ℃only at 20-30 ℃ temperature environment, it is a great challenge to design ( especially efficiency indicators ) to ensure the drive reliability at such a high temperature environment.
Second, long-term work at full capacity .
The driver of high power LED flood light and other power LED light is close to full capacity without dimming , while the vast majority of applications in switching power supply , such as computer power supply ( adapter ) , communication power supply , and household appliances , an average power of long-term work is usually only a fraction of rated power，all the loads turned on full power state only appears a few times in a particular .
Third, for high power LED flood light and other outdoor lighting applications on roads, squares , etc., they are vulnerable to external damage to natural phenomena such as lightning . All these will result in ongoing maintenance and other ills of large-scale application of high power LED flood light and other LED semiconductor lighting.
The high reliability of drive of high power LED flood light and other LED light is an important condition for product quality , but also is the urgent technical problems compromised .Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about high power LED flood light.
