Embodiment Construction

[0008] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0009] See attached figure 1 , is a schematic diagram according to an embodiment of the present invention, including a bulb shell 1, a lamp cap 2, a power circuit 3, a stem 4, and a filament unit 5 arranged inside the bulb shell 1. The filament unit 5 includes a filament base, and is arranged on the filament base. The LED chip on the LED chip and the connecting terminals arranged at both ends of the filament matrix. The filament matrix is ​​stamped from a transparent sheet into a plane spiral structure and stretched and fixed along the z-axis to form a three-dimensional conical spiral structure. The stem 4 includes a pair of conductive materials. Connectors 6, one of which is connected to the bo...

Description

technical field [0001] The invention relates to the technical field of LEDs. Background technique [0002] The lighting effect of LED bulbs usually has a problem with a certain emission angle, so the lighting effect is different from expectations. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a lighting device with a new structure, which can provide better lighting effects. [0004] In order to achieve the above object, the present invention provides a lighting device, which includes a filament substrate, an LED chip arranged on the filament substrate, and connecting terminals arranged at both ends of the filament substrate, and the filament substrate is punched into a planar spiral structure by a transparent sheet And it is stretched and fixed along the z-axis direction to form a three-dimensional conical helical structure. [0005] According to another aspect of the present ...
