Abstract
This invention discloses an AC LED filament including two parallel LED arrays in counter conduction directions, in which, the LED arrays are composed of several serial LED and connected by a lateral current in between to form a lattice structure. This invention also provides an AC LED lamp applying said filament. Advantage: the adjacent two sets of LED are protecting elements mutually by applying a lateral circuit to connect two arrays of LED in counter conducting directions, if one set is lost, the other set of LED parallel to it and in the opposite direction can provide a current path to continue the work.
Description
[technical field]
The present invention relates to a kind of lighting apparatus, specifically relate to a kind of AC LED filament and illuminating lamp.
[background technology]
Applicant of the present invention has submitted to a name to be called the Chinese invention patent application of " AC LED lighting lamp " on 03 04th, 2005, application number is 200510020493.6.Disclosing a kind of in this part patent application is the AC type lighting of light source with LED (Light-emittingdiode light-emitting diode).This kind light fixture adopts AC LED filament, can directly be connected on the AC power and use, and has efficient, economic dispatch plurality of advantages.After application was submitted to, the inventor was in master's the circuit structure through further testing and discovering adopting the series connection form, in case if certain LED open failure, to cause whole loop to be lost efficacy, failure rate is single led several times, and multiple equals the progression of connecting.Adopt latticed array structure to damage in the LED lamp of the same sense of current though have been proposed in this patent with the open circuit of tackling indivedual LED, but do not replenish owing to there be the auxiliary of other approach, other LED that connects with damage LED still can be a greater impact, and therefore also needs better scheme for the reliability that improves integrated circuit.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of illuminating lamp that has the AC LED filament of high reliability more and use this kind filament.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of AC LED filament, comprise the light-emitting diode row that at least two row conducting directions in parallel are opposite, described light-emitting diode is listed as by several light-emitting diode series connection and forms, also have transverse circuit between the described two row light-emitting diodes row and connect, form fenestral fabric.
Preferably, described two row light-emitting diodes are listed as by the series connection of the identical light-emitting diode of quantity and form, and the opposite light-emitting diode of per two conducting directions side by side is by transverse circuit and connect.
And a kind of AC LED filament is unified into behind the row again by some AC LED unit strings that parallel connection constitutes, and described AC LED unit is made of two opposite light-emitting diode parallel connections of conducting direction.
Be purpose of the present invention, a kind of AC LED lighting lamp also is provided, comprise ac input end and be connected AC LED filament between the ac input end, described AC LED filament has said structure.
Adopt technique scheme; beneficial technical effects of the present invention is: adopt transverse circuit to connect the opposite two row light-emitting diodes row of conducting direction; make two groups of adjacent LED protection component each other: in case certain LED open failure in a group wherein; another group LED of reverse parallel connection can provide current channel with it; although it is should inefficacy LED no longer luminous; but Chuan Lian other LED still can work on it; influence is little concerning integrated circuit, and this moment, operating current was " reverse leakage current " of the reverse LED in parallel with inefficacy LED.Reverse leakage current has become the condition that can be utilized like this, just can significantly loosen the requirement of " reverse voltage ", " reverse leakage current " on technology, can corresponding raising rate of finished products.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
[description of drawings]
Fig. 1 is a kind of AC LED filament circuit diagram.
Fig. 2 is another kind of AC LED filament circuit diagram.
Fig. 3 is a kind of AC LED lighting lamp circuit diagram.
[embodiment]
Embodiment one, a kind of AC LED filament, in conjunction with Fig. 1, comprise the light-emitting diode row that two row conducting directions in parallel are opposite, described two row light-emitting diodes are listed as by the identical light-emitting diode series connection of quantity and form, the opposite light-emitting diode of per two conducting directions side by side is by transverse circuit and connect, and forms fenestral fabric.
Embodiment two, another kind of AC LED filament in conjunction with Fig. 2, are connected into behind the row again by some AC LEDs unit A that parallel connection constitutes, and described AC LED unit is made of two opposite light-emitting diode parallel connections of conducting direction.
Adopt the structure among above-mentioned two embodiment, when certain the LED open failure in the filament, another LED of reverse parallel connection promptly provides auxiliary current channel with its " reverse leakage current " for the series loop at this damage LED place with it, makes this damage produce the little influence of trying one's best to integrated circuit.
Embodiment three, a kind of AC LED lighting lamp in conjunction with Fig. 3, comprise ac input end a1, a2 and are connected AC LED filament between the ac input end that described AC LED filament adopts the structure described in the embodiment one.
Adopt the AC LED filament of structure of the present invention to adopt its global reliability index of filament of cascaded structure approximately can improve 25～50% more merely.
