Fiber type LED filament lamp

Abstract

The invention relates to the technical field of lighting lamps, in particular to a fiber type LED filament lamp. The fiber type LED filament lamp comprises a lampshade, an LED light emitting body, a lamp holder and a support. The LED light emitting body is arranged on the support. The lampshade is arranged on the support in a covering manner. The support is arranged on the lamp holder. A drive power source is arranged in the lamp holder. The LED light emitting body is installed at the top end of the support. The LED light emitting body is in a closed or semi-closed polygon shape formed through connecting and defining of a plurality of sections of transverse filaments in an end-to-endmanner. The two ends of the LED light emitting body are electrically connected with the drive power source through a positive electrode lead and a negative electrode lead. According to the fiber type LED filament lamp, the length of the filaments is reduced, cost is reduced, and meanwhile the light emitting efficiency of an original filament is guaranteed. The technical problem that in the prior art, the length of a filament and the light emitting efficiency are directly proportional is solved. In addition, by means of arrangement design of the filaments, the heat dissipation efficiency is guaranteed, all-direction lighting can be guaranteed, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lighting lamps, in particular to a fiber-shaped LED filament lamp. Background technique [0002] At present, LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electric energy into light energy. LED lights have the characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the existing LED lamp filaments are generally arranged around the support in a longitudinal manner, such as figure 1 As shown, there are two defects in this way: one is that the lampshade should be adapted to the length of the filament, which increases the length of the lampshade; the other is that the length of each section of LED filament is generally 20-40mm, and the length of the filament is...

Problems solved by technology

However, the existing LED lamp filaments are generally arranged around the support in a longitudinal manner, such as figure 1 As shown, there are two defects in this way: one is that the lampshade must be adapted to the length of the filament, which increases the length of the lampshade; the other is that the length of each LED filament is generally 20-40mm, and the length of the filament is longer, which increases the production cost.

[0003] If the length of the LED filament can be reduced, the above two technical problems can be solved, but if the length of the LED filament is reduced, its power will be reduced and the luminous effect will be affected. This is where the contradiction lies.
