Present problems in LED lamps

Stability of LED driver is not enough at high temperature

R li bili f LED d i d h l l i hReliability of LED driver and whole lamps is not enough

Early failure rate of whole lamps is too high

Question：Expecially in China Market, there are many problems in l i d h lif h dLED lamps in 2012 and 2013 such as life cannot meet the expected

requirement, early failure rate is too high, because of that the capacitor quality cannot meet high requirement.

All the problems in LED driver

—— are caused by the low stability and short life when small-sized capacitors works in a high temperature and large ripple current environment.

Because:

Two weak points in capacitor maufacturers：

1. Previous capacitor manufacturers for CFL and electronic ballast don't have too much h l i l d d i i f i i i i f i i ll i htechnological and production experience after miniaturization of capacitor, expecially in the

requirement of enduring high temeprature & large ripple current and long life

2.Previous capacitor manufacturers for power supply are not familiar with the capacitor's performance in lighting,like the high temperature,large ripple current and high requirement of overload.

The technology of LED driver comes from integration of two kinds of technology,one is lighting technology, another is power supply technology.

In LED lighting, YMIN is more professional than Japanese R company:g g, p p p y

The electrical properties are more stable at high temperature

The early failure rate is less

Working life is much longer

The size is much smaller based on same specification and same lifelife.
