7, owing to adjusting potential device and light emitting module to integrate, the manufacturing cost increasing light fixture is high, reduces the cost performance of CFL lighting system;
8, system lifetim depends on the tune potential device that the life-span is shorter or wherein shorter one of LED light emitter.Particularly after superposing with the thermic load of photophore, adjust the life-span all effected of potential device or LED light emitter, reduce the reliability of each parts, thus shorten the life-span of whole system;
9, when no matter being that photophore module damage or tune potential device damage, then whole system will all be thrown away, and comprises applicable part wherein.Scrap light fixture and can produce huge social resources waste, comparatively overall situation can be produced simultaneously and pollute;
Although 10 illuminations use be low-voltage, because this system is docked with on 220 V high-tension electricities as a whole, the security of system is not high.
Summary of the invention
