Abstract

The invention discloses an LED (Light Emitting Diode) bulb lamp with a driving power supply integrated in a bulb shell. The LED bulb lamp comprises the bulb shell, a core column, a power supply drive, multiple LED luminous lamp filaments, heat conduction gas and a lamp holder, wherein the power supply drive is fixedly arranged on the core column; the LED luminous lamp filaments are connected with the power supply drive; the bulb shell is filled with the heat conduction gas; the lamp holder is connected with the bulb shell; each LED luminous lamp filament comprises a substrate; the surface of each substrate is provided with a metal circuit and a bottom adhesive layer; two ends of each substrate are provided with metal pins; each substrate is fixedly provided with an LED luminous unit; each LED luminous unit is provided with a sealing adhesive layer. According to the LED bulb lamp disclosed by the invention, the power supply drive is arranged in the bulb shell, an existing manual assembling link is avoided, large-scale automatic production can be realized, and the production cost is substantially reduced; the lamp filaments adopt an optimized chip arranging type, the temperature of each substrate in different positions is nearly uniform, the luminous flux maintenance rate and the long-term reliability of the whole LED bulb lamp are increased, and the service life of the LED bulb lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of LED lighting equipment, in particular to an LED bulb lamp with a driving power integrated inside the bulb shell. Background technique [0002] The filaments of traditional lighting fixtures are generally composed of tungsten wires and other metal wires that can emit light directly. Such filaments generally have defects such as short life and high power consumption. LED light sources have the characteristics of energy saving, longevity, environmental protection, and solid-state packaging, making LED lights gradually replace traditional lighting fixtures. Existing LED lights are generally equipped with light-emitting modules, including square or round brackets, and LED chips set on one side of the bracket. , and a lens coated on the surface of the LED chip. The LED light bar adopts a transparent substrate, which can realize 360° full-angle light without using a lens, and becomes a three-dimensional light s...
