Full-angle high-luminance light-emitting lamp filament bulb and manufacturing method thereof

Abstract

The invention provides a full-angle high-luminance light-emitting lamp filament bulb and a manufacturing method of the full-angle high-luminance light-emitting lamp filament bulb. The full-angle high-luminance light-emitting lamp filament bulb comprises full-angle light-emitting lamp filaments, a core pillar, an LED light-emitting substrate, a lampshade, heat conduction gas and a lamp holder. A horn-shaped opening is formed in one end of the core pillar so that the core pillar and the lampshade can form a sealed bulb body, and the bulb body is provided with a core pillar exhaust pipe and filled with the heat conduction gas. The core pillar stretches into the lampshade and is connected with one or more full-angle light-emitting lamp filaments through a conduction leading-out wire or conduction leading-out wires, one end of each full-angle light-emitting lamp filament is connected with the corresponding conduction leading-out wire on the core pillar, and the other end of the ach full-angle light-emitting lamp filament is connected with the LED light-emitting substrate to form a loop. The full-angle light-emitting lamp filaments comprise a support and a light-emitting chip fixed to the surface of the support. The LED light-emitting substrate comprises a substrate body and a light-emitting chip arranged on the substrate, and a conduction layer is arranged on the substrate body and connected with an electrode of the light-emitting chip.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to an all-angle high-illuminance light-emitting filament bulb and a manufacturing method thereof. Background technique [0002] LED (Lighting emitting diode) lighting technology has been welcomed for its low operating voltage, small operating current, good shock and earthquake resistance, high reliability, long life, and easy adjustment, and has become a widely used lighting technology. technology. [0003] The existing LED filament light bulb lighting equipment all adopt straight filaments, and the edge of the support of the straight filaments is straight. Straight filaments are installed in the bulb in a straight line or slightly inclined. Due to the unique light distribution curve of each filament, through the reflection (refraction) of phosphor powder, the brightness on both sides of the bulb will be high, while the illumination at the bottom will be very low.
