Second, the conventional protective measures can do it?
Looking at the LED industry guardrail protection measures are basically plug in both ends of the head of external protection, from the guardrail work environment analysis, depending on the area, tube to be able to withstand: heat,
cold, sun , rain, drying and other harsh environmental factors tested, factory seem foolproof, but the use of the process, but the problem continued, where the root cause? In fact, many companies ignore the few details in the prenatal, (a): the warranty period, the failure rate of the early components was about 0.3% -1%, the actual failure rate due to enterprise quality control of components vary. LED Module
(Two): guardrail fence moisture in the air due to temperature and pH changes of substance to the component's erosion, its damage rate of about 4% -7%. (Three): Splitting shell accidents, damage caused by plug degumming rate of about 2% -6%, the failure rate due to the specific manufacturer of the shell material selection and there are differences.
Seen, the tube circuit board protection The fundamental problem is, the conventional water only for protection against external measures can not achieve true protection purposes guardrail, guardrail system can not be met in the high failure rate.
