Embodiment 1

[0036] refer to figure 1 , an LED filament lamp, comprising: a bulb 1, a flexible LED filament module, a rotating device 3, a flexible LED filament module and a supporting device 4 of the rotating device 3;

[0037] The flexible LED filament module includes at least one helical flexible LED filament 2, the first end of the flexible LED filament 2 is connected to the supporting device 4, and the second end is connected to the rotating device 3;

[0038] The rotation of the rotating device 3 drives the number of helical turns of the flexible LED filament 2 to change, and at the same time, the diameter of the helix also changes. Therefore, when the flexible LED filament 2 is turned on, the number of turns of the flexible LED filament 2 can be changed, and the diameter of the flexible LED filament 2 can be changed at the same time. This makes the shape of the flexible LED filament module changeable. It can also be set that when the flexible LED filament 2 is turned on, the helic...

Embodiment 2

[0042] refer to figure 2 , in this embodiment, in order to realize the rotation of the rotating device 3, it also includes a stem 5 extending axially along the bulb 1; the lower end of the stem 5 along the axial direction is fixed to the supporting device 4;

[0043] The rotating device 3 is sheathed on the stem 5 ; the rotating device 3 rotates around the axial direction of the stem 5 while moving along the axial direction of the stem 5 . That is to say, through the cooperation between the rotating device 3 and the stem 5 , the translation of the rotating device 3 along the axis of the stem 5 is reversed to the rotation around the axis of the stem 5 .

[0044] In order to achieve the above effects, the rotating device 3 and the stem 5 are connected by threads. Specifically, the inner diameter or inner thread of the rotating device 3 matches the outer thread of the stem 5, such as image 3 shown.

[0045] Therefore, when the rotating device 3 is subjected to external force...

Embodiment 3

[0049] refer to Figure 5 , in this embodiment: in order to realize the rotation of the rotating device 3, it also includes a stem 5 extending axially along the bulb 1; the lower end of the stem 5 along the axial direction is fixed to the supporting device 4; it also includes a A telescopic device 6 that drives the rotating device 3 to rotate; one end of the telescopic device 6 is sleeved outside the stem 5 and abuts against the rotating device 3, and the other end passes through the supporting device 4 and is connected to the drive circuit;

[0050] In order to achieve the above effects, the rotating device 3 and the stem 5 are connected by threads. Specifically, the inner diameter or inner thread of the rotating device 3 matches the outer thread of the stem 5, such as Figure 6 shown.

[0051] The telescoping device 6 drives the rotating device 3 to move along the axial direction of the stem, and the rotating device 3 rotates around the axial direction of the stem 5 while ...

Abstract

The invention provides an LED filament lamp. The LED filament lamp comprises a bulb shell, a flexible LED filament module, a rotating device and a supporting device. The flexible LED lamp filament module comprises at least one spiral flexible LED lamp filament; a first end point of the flexible LED lamp filament is connected with the supporting device, and a second end point of the flexible LED lamp filament is connected with the rotating device; the rotating device rotates to drive the number of spiral turns of the flexible LED lamp filament to change, and meanwhile the spiral diameter also changes. According to the LED filament lamp, the spiral turns of the flexible LED filament can be changed, and meanwhile the spiral diameter of the flexible LED filament can be changed. Therefore, theshape of the flexible LED filament module can be changed. And when the flexible LED filament lamp is lightened, the spiral diameter of the flexible LED filament is increased, the vertical distance from the flexible LED filament to the bulb shell is shortened, a better heat dissipation effect is achieved, the temperature of the flexible LED filament is reduced, the light attenuation speed of the flexible LED filament is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a filament lamp. Background technique [0002] The popular white LED filament lamps on the market need to avoid the silicone on the surface of the flexible LED filament from being scratched, and the extrusion of the silicone surface also has the risk of damaging the LED chip and the electrical connection of the chip. The flexible LED filament module formed by the flexible LED filament after spiral molding is vertical LED The maximum size of the surface of the central axis of the bulb is smaller than the minimum diameter of the opening of the bulb. The spiral shape of the flexible LED filament is fixed and cannot be adjusted. At the same time, the vertical distance between the flexible LED filament and the bulb is relatively long in this solution. The wattage of the popular flexible LED filament lamps on the market is less than 6W, and the luminous flux is not enough to replace the 60W in...
