LED bulb structure

Abstract

The invention relates to an LED bulb structure. The LED bulb structure comprises a glass core column, a first power supply wire, a second power supply wire, a first electric conducting column, a second electric conducting column, a first light emitting module, a second or multiple light emitting modules and multiple fixed balls. The first light emitting module and the second or multiple light emitting modules respectively comprise an upper bracket set and a lower bracket set; one ends of the upper and lower bracket sets are joined with the first electric conducting column, and the other ends of the upper and lower bracket sets are joined with the second electric conducting column; and multiple lamp filaments are arranged between the upper and lower bracket sets at intervals. As LED modular lamp filament structures are serially connected, the multiple LED lamp filaments can be modularized, the LED modules are stacked and joined in a parallel connecting manner, the lumen number can be effectively increased, and the brightness is promoted.

Description

technical field [0001] The present invention relates to an LED light bulb structure, in particular to an assembly structure of multi-layer stacked LED filaments (LED filament) in an LED filament light bulb. Background technique [0002] Nowadays, the structure technology of LED light bulbs is constantly improving. There are LED light bulb products on the market. In order to increase the brightness, in the series and parallel connection of several LEDs, there are printed circuit boards that are easy to arrange circuits in the prior art. For example, the "LED lighting lamp" of Taiwan Utility Model Patent No. M389204 mainly uses two circuit substrates with LED lamp modules as the wicks of its LED bulbs in a cross-staggered insertion manner. However, in addition to the problem of heat dissipation in this technology, the number of lumens of the lighting is also reduced because the LED lamp is shaded by the circuit substrate. [0003] Another kind of existing LED light bulb techn...

AI Technical Summary

Problems solved by technology

[0007] 1. The material of the glass column 100 supported by the center is fragile and can no longer withstand the weight of multiple LEDs and their structures and the resulting shaking

If you want to increase the number of lumens to increase the brightness, due to its own structural limitations, it is impossible to increase the number of LED filaments in the way of module superposition, and it is impossible to increase the number of filaments in a modular way

[0008] 2. In the parallel connection mode required by the LED circuit, according to Figure 5 The known technology, because the LED is too far away from the power lines 21a, 22a, it is impossible to extend the circuit in parallel

[0009] 3. If the number of LED lamps is to be increased, the breakpoint must be increased, which causes the structure to be loose, and the conductive wire structure is easy to shake, causing the LED filament to swing, and its structure is quite unstable
