Embodiment

[0024] Example: A new type of driverless LED filament lamp of this example, such as figure 1 As shown, it includes a bulb 1 and a lamp cap connected to the bottom of the bulb 1, the bulb 1 is provided with a stem 4 connected to the lamp cap inside, the stem 4 is surrounded by a number of filaments 5, the stem 4 There is a current conversion device on it. The bottom of the lamp holder is the live wire terminal 2 of the lamp holder, the connection between the lamp holder and the bulb is the neutral wire terminal 3 of the lamp holder, the stem is used to set the circuit structure and filament, and the current conversion device is used to realize the conversion of alternating current to direct current and filter the current to prevent waves. Surge optimization.

[0025] The current conversion device includes a sorting bridge stack DB17 and an electrolysis assembly 8 connected in sequence, the sorting bridge stack DB17 is connected to the AC input end, and the filtering electrolys...

Abstract

The novel drive-free LED filament lamp comprises a bulb shell and a lamp holder connected with the bottom of the bulb shell, a core column connected with the lamp holder is arranged in the bulb shell, a plurality of lamp filaments are arranged on the periphery of the core column in a surrounding mode, and a current conversion device is arranged on the core column. According to the technical scheme, the input alternating current is converted into the direct current after passing through the cooperation of the bridge rectifier, the electrolyzer, the fuse and other components, an integrated driving module is replaced to save the assembly process of the integrated driving module, the same function is achieved through the cooperation of electronic components, the working efficiency is improved on the premise that the service life of the whole lamp is not affected, and the cost is reduced. And the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a novel non-driven LED filament lamp. Background technique [0002] As the fourth generation of green, energy-saving, power-saving and long-life lighting fixtures, LED light sources have emerged, attracted wide attention, and developed rapidly. The current LED light source is a low-voltage, high-current semiconductor device, which must provide a suitable DC current to emit light normally. The technology of DC-driven LED light source has become more and more mature. Since the power supply used in our daily lighting is high-voltage AC (AC100 ~ 220V), we must use step-down technology to obtain lower voltages, commonly used transformers or switching power supplies Step down, then convert the AC to DC, and then convert it into a DC constant current source, in order to promote the LED light source to emit light. Therefore, in the prior art LED lamps, there must be a certain space f...
