Embodiment 1

[0056] like figure 1 As shown, this embodiment includes an electroplating lamp cap 1 , a bulb 2 , a horn tube 3 , a stem 4 , an LED filament 5 and a support member 6 , and the electroplating lamp cap 1 is provided with an LED driver electrically connected to the electroplating lamp cap 1 .

[0057] The bottom end of the bulb shell 2 is fixed to the electroplating lamp cap 1, the main body shape of the bulb shell 2 is cylindrical, and the top is an arc surface.

[0058] The horn tube 3 is arranged in the bulb 2, the bottom of the horn tube 3 is fixed to the bottom of the bulb 2 to form a closed cavity in the bulb 2, and the horn tube 3 is provided with an exhaust pipe 33.

[0059] The stem 4 is located in the airtight cavity, and is vertically fixed on the top of the horn tube 3 , the stem 4 is hollow and communicates with the inside of the horn tube 3 .

[0060] The flexible LED filament 5 spirally surrounds the stem 4 and the outside of the trumpet tube 3, so that the entire...

Embodiment 2

[0065] The difference between this embodiment and Embodiment 1 lies in the structure of the support member 6 .

[0066] like image 3 As shown, in this embodiment, the outer surfaces of the stem 4 and the trumpet tube 3 are provided with an annular groove 61, and the support member 6 includes a fixing ring 62 sleeved in the annular groove 61, and a plurality of one ends are fixed to the fixing ring 62. , the other end is bent into a short metal wire 63 in the shape of a hanging ring, and the hanging ring part of the short metal wire 63 is socketed with the LED filament 5; in this embodiment, according to the shape of the spiral LED filament 5, each fixing ring 62 is provided with Three short wires 63 . The short metal wire 63 can freely bend the hanging ring to hook the key parts of the LED filament 5, and fix the LED filament 5; the short metal wire 63 can also swing up and down, left and right, so as to adjust the position of the hanging ring to match the LED filament 5 in ...

Embodiment 3

[0068] The difference between this embodiment and Embodiment 1 lies in the structure of the support member 6 .

[0069] like Figure 4 As shown, in this embodiment, the support member 6 is a long metal wire 64, the middle part of the long metal wire 64 is wound around the stem 4 or the trumpet tube 3 at least one turn, and both ends of the long metal wire 64 are bent into a hanging ring shape And be connected with LED filament 5. It is more convenient to connect and fix through the long metal wire 64. After the long metal wire 64 is wound and tightened, the fastening effect on the LED filament 5 is better. Sliding up and down or falling off; and the whole supporting member 6 is composed of a long metal wire 64, which is convenient for replacement and length adjustment, so as to adapt to LED filaments 5 of different shapes.

[0070] In this embodiment, due to the connection characteristics of the long metal wire 64, there is no need to provide an annular groove 61 on the stem...

Abstract

The invention discloses a flexible LED filament lamp. The flexible LED filament lamp comprises a lamp holder, a bulb shell, a horn-shaped pipe, a core column and a flexible LED filament, wherein the bottom end of the bulb shell is fixed to the lamp holder, the horn-shaped pipe is arranged in the bulb shell and the bottom end of the horn-shaped pipe is fixed to the bottom of the bulb shell, the core column is vertically fixed to the top of the horn-shaped pipe, and the flexible LED filament is arranged in the bulb shell. The lamp holder is internally provided with an LED drive electrically connected with the electroplating lamp holder, the LED filament is electrically connected with the LED drive, and the horn-shaped pipe is internally provided with an exhaust pipe. The LED filament is arranged around the core column and the horn-shaped pipe simultaneously, the top end of the LED filament is close to the top of the core column, and the bottom end of the LED filament is close to the bottom of the horn-shaped pipe. The outer surface of the core column and the outer surface of the horn-shaped pipe are both provided with supporting pieces for supporting the LED filament. The illumination of the whole LED lamp filament can be more uniform, no obvious bright and dark area exists, and the lighting and visual effects are better; and connection routes of two guide wires are arranged separately, contact between the connection routes in the horn-shaped pipe is avoided, the size of the horn-shaped pipe can be reduced, people cannot find the horn-shaped pipe within the line of sight easily, and the attractiveness of the whole LED lamp filament is improved.

Description

technical field [0001] The invention relates to the field of LED filament lamps, in particular to a flexible LED filament lamp. Background technique [0002] At present, hotels, restaurants, cafes, bars and other public places often use Edison retro bulbs for lighting. Edison's retro light bulbs use tungsten wires, which are wound into various shapes, such as spiral, T-shaped, and various animal and plant shapes, and combined with bulbs of various shapes to form a retro shape. Its soft light and shape, Provides a good public environment. However, tungsten wire is being replaced by LED lamps due to its own defects, such as high power consumption, short service life, and easy to get hot. [0003] LED lamps have low cost, low energy consumption and long service life, and have gradually replaced incandescent lamps in terms of lighting. However, the commonly used LED lamps are to install LED chips on the lamps, and emit light from the lamps when in use. Generally, they cannot ...
