LED FILAMENT AND ILLUMINATOR

摘要

An LED filament and an illuminator using the LED filament. The LED filament comprises a metal framework (1) and a fluorescent adhesive (2). A middle part of the metal framework (1) is a die bonding area (11). Multiple LED chips (3) are arranged in the die bonding area (11). Two ends of the die bonding area (11) are respectively provided with a plastic element (4) used for preventing the liquid-form fluorescent adhesive (2) from overflowing. The liquid-form fluorescent adhesive (2), after cured, coats a part of the metal framework where the die bonding area (11) is located. Light emitted by the LED chips in the die bonding area excites the surrounding fluorescent adhesive to generate light of a required color, thereby solving a blue leakage problem of the LED filament. The LED filament can be applied in various illuminators.
