Description

A kind of tubulose LED bulb

Technical field

The utility model belongs to LED bulb technical field, is related to a kind of tubulose LED bulb.

Background technology

LED bulb is similar to ordinary filament bulb profile, and difference is that LED bulb is the ordinary lamps using LED light bar as filament Bubble then uses tungsten filament.And when LED filament and LED filament lamp body are electrically connected, it is typically all that all series connection or part are gone here and there The mode of connection of connection.The problem of complex process thus be present.Meanwhile when one or part LED filament are failed, easily cause LED filament lamp integrally extinguishes, it is clear that the problem of service life is short be present.But the general filament lamp of prior art structure or Do not solved the above problems effectively in manufacture craft.

Such as a kind of LED filament bulb that Chinese patent Authorization Notice No. is CN203940268U, the Patent Case disclose A kind of structure of LED filament bulb, it is real by LED filament, driving power, support, bulb and the isostructural combined innovation of lamp holder Having showed the LED filament bulb has the characteristics of stable performance and high conversion efficiency, but the LED die in the Patent Case is The structure of series connection, when LED die fails, easily cause LED filament lamp and integrally extinguish, there is that service life is short to ask Topic.

Utility model content

The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of multiple LED light bars exist It is arranged in parallel in circuit, improves the tubulose LED bulb of service life.

The purpose of this utility model can be realized by following technical proposal：A kind of tubulose LED bulb, including stem, electricity The transparent bulb case of connector and tubulose, it is characterised in that transparent bulb case is connected with electric connector, stem be located in transparent bulb case and Vacuum sealing cavity is formed with transparent bulb case vacuum sealing, positive lead-out wire and negative lead-out wire, stem upper surface are equipped with stem It is fixed with two support columns parallel with transparent bulb case length direction, positive lead-out wire and other point of negative lead-out wire and respective support column It is fixed, some LED light bars are provided with transparent bulb case, LED light bar is weldingly fixed between positive lead-out wire and negative lead-out wire, electrical connection Driver is provided with device, positive lead-out wire and negative lead-out wire lower end are connected with driver, and driver passes through connecting line and electric connector Connection.

Realize that all LED light bars are accessed in circuit by the way of in parallel, not only manufacture craft is simple, and at one Or during the failure of part LED light bar, remaining LED light bar continues to light, and extends the service life of the LED bulb.It is positive to draw Line and negative lead-out wire wiring distance are remote, and are obstructed by support column, it is not easy to short circuit.

In above-mentioned tubulose LED bulb, the quantity of the LED light bar is 4-6.

In above-mentioned tubulose LED bulb, the LED light bar joins end to end successively.

Alternatively, in above-mentioned tubulose LED bulb, the LED light bar be arranged in parallel.

In above-mentioned tubulose LED bulb, the support column is clear glass, and positive lead-out wire and negative lead-out wire are respectively positioned on branch In dagger.Support column is also glass material, after LED light bar is welded, then glass heating is melted in into two lines periphery and forms branch Dagger, positive lead-out wire and negative lead-out wire are respectively positioned in support column, as long as support column does not move, both threads will not encounter together, rise To barrier away from effect, prevent two linear contact lays and short circuit occurs.

In above-mentioned tubulose LED bulb, two support column upper ends are connected by connecting rod.Made by the connection of connecting rod With making the connection of two support columns more firm.

Compared with prior art, this tubulose LED bulb has advantages below：

1. positive lead-out wire and negative lead-out wire are separately obstructed farther out and by support column, it is not easy to short circuit.

2. individual LED light bar more than is is connected in parallel, and when a LED light bar fails, remaining LED light bar can also normally complete illumination Work, improve the life-span of whole LED bulb.

The distribution of 3.LED lamp bars is scattered, and is lighted uniform, good heat dissipation effect.
