The implementation of incandescent lamp plan, tungsten incandescent lamp are about to disappear, and LED filament lamp gradually replaces ground of the tungsten lamp in the minds of people
Position.Filament lamp due to packaging technology yield is low and weak heat-dissipating and raw material transportational process in cracky, envelope bubble technology it is stringent
It is required that causing filament lamp manufacturing cost high, LED filament lamp is hindered to be difficult to come into common people house.Wherein LED filament encapsulating products
Weak heat-dissipating and this high two hang-up of fraction defective, annoying always LED encapsulation personnel.
LED filament is substantially without radiator, and substrate is usually the very poor glass material of heating conduction, and electrode, which does not have, yet leads
Hot property, LED filament can not carry out heat conducting and radiating, so being difficult to conduct the heat that LED chip generates, heat can only
Thermally conductive and heat dissipation is carried out by radiation and the convection current of internal gas, the accumulation of heat is be easy to cause, so that the service life of LED filament contracts
It is short.Heat is in LED filament building up inside simultaneously, it is most likely that it is empty to will cause solder joint of the LED filament in production and use process
It connects or falls off, show as LED filament lamp flashing light or dead lamp.
