In addition, the SMD lamp bead welding plate will short circuit caused by water vapor into, single light source short circuit caused a series of circuit breakers, causing part of lamp is broken, harmful gas into lead to the light source surface is colloid sulphur corrosion, colloid cracking caused wire breaking and then lamp bad. Second, the insufficient cooling: survey found that most of LED street light used the radiator, heat dissipation area in order to save cost, hot and cold than beyond reasonable rang...
