How to prolong the life of led flood lights? So we buy LED flood lights (all not specifically led spotlights), we must see its thermal design good. It can be concluded from the diagram that the key to prolonging the lifespan is to reduce the junction temperature.
The key to reduce the junction temperature is to have a good radiator, can be timely to produce the heat emitted by the LED flood light fixtures. Here we are not going to discuss how to design the radiator, but to discuss which radiator has a relatively good cooling effect.
In fact, this is a temperature measurement problem, if we can measure any kind of radiator can reach the junction temperature, then not only can compare the heat dissipation effect of various radiators, but also can know the use of this radiator can be achieved after the LED’s life.
