Introduction of LED modular Bulb
What are LED bulb? Unique FeaturesLED bulb typically are constructed of a series of surface-mount LEDs soldered to a copper circuit layer that is separated from a base, which is frequently aluminum and typically rigid although flexible base materials are now being used, by an electrically isolating, heat conductive dielectric material making for a very compact, durable light assembly.
Generally, electrical interconnection is made via a removable wire connector soldered to the LED bulb's conductive copper layer. Long life LED bulbs which are generally LED bulbs made up of surface-mount LEDs with a 3U and 4U, are the latest thing in lighting today due to their high brightness and relative efficiency.
Isolated moudlar electric designIt adopts the insolated electric design with aluminum base to avoid the heat is too much reduce the life span; its double silicon-rubber rings insulate LEDs with the outside environment completely, thus to eliminate any erosion to chips and PCB boards from outside.The base can made to E27, B22, G24,
“Ultra Robust” heat sinkEach LED is equipped with bypass protection, to protect single-circuit structure of the full connection series, even open or short circuit fault can’t affect current and voltage distribution of other LED, the other LED can work under the normal operating mode.
Typical Advantages:Offer cool lighting with a very long life expectancyEfficiency: maximum light outputEasy to get different lighting applications Chips AppliedLED Bulbs = Long lifespan Only Qualified "Epistar"
LED Modular bulb = Long life spanAs long life lighting series are based on the modern technology of best heat sink; it is quite easy for our designers to get the follow application.
