Problems solved by technology

However, the soft filament made of FPC has disadvantages such as the thermal expansion coefficient of FPC is different from that of the silica gel covering the filament, which leads to the displacement or even degumming of the LED chip after long-term use; or FPC is not conducive to the flexible change of process conditions, etc.

Embodiment Construction

[0210] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, the implementation of the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0211] During the manufacturing process of traditional bulb lamps, in order to prevent the tungsten wire from burning in the air and causing oxidative fracture failure, a horn stem glass structure is designed to be sintered and sealed at the opening of the glass lamp housing, and then penetrated The port of the horn stem is connected to a vacuum pump to replace the air inside the lamp housing with nitrogen to prevent the tungsten wire inside the lamp housing from burning and oxidizing, and finally the port of the horn stem is sintered and sealed. In addition, the water mist scattered in the air inside the lamp housing can also be removed through the pumping of the gas. Further, please refer to Figure 1A...

Abstract

The invention discloses an LED filament, a manufacturing method of the LED filament, and an LED bulb equipped with the filament. The LED filament comprises multiple LED chips, at least two poles, an auxiliary strip and a light conversion layer. Wherein the poles and the LED chips are electrically connected, the LED chips and the poles are covered by the light conversion layer, the light conversion layer comprises silica gel silica gel and phosphor, the auxiliary strip is arranged on the light conversion layer along an axis direction of the LED filament. The LED filament can give out light in all directions, and all-direction illumination requirements of the bulb equipped with the LED filament can be further satisfied.
