  • service life and reliability of the LED lamps depend on temperature. If heat generated by LED lamps cannot be properly dispersed out, it is to make LED interface over heated to downgrade light emitting efficiency, stability and service life. That is, the higher the temperature is, the shorter the service life is.
  • an LED module is usually the only component that is apt to break down. So a heat dispersing module, such as heat dispersing fins or tubes, is always additionally installed in an LED lamp to step up dispersing effect. But, with the heat dispersing module, it is to augment structural complexity, manufacturing cost and assembling difficulty of the LED lamp.
