A technical scheme is that the cylindrical LED filament is characterized in that the cylindrical LED filament comprises a support, a group of LED light-emitting chips mutually connected in series, and a light-transparent layer wrapped around the support and the LED light-emitting chips, that the support comprises a substrate and two conductive pins respectively disposed on the two ends of the substrate, that the two conductive pins and the substrate are connected by an insulating member to form a long strip shape, that the LED light-emitting chips are arranged on one side of the substrate, that the head end of the group of LED light-emitting chips connected in series is connected with one conductive pin through a wire, and that the tail end of the group of LED light-emitting chips connected in series is connected with the other conductive pin through another wire.

Description

A kind of column LED filament
Technical field
The utility model relates to lighting technical field, particularly a kind of column LED filament.
Background technology
Because the LED filament adopts LED as light source, there is luminous efficiency preferably, its application is more and more extensive.
Existing LED filament is arranged on the LED luminescence chip on the substrate of heat conduction, and usually substrate be circular, can only be on circular substrate distribution LED luminescence chip, and formation sphere shape light, its form of light source is single, can't form the column light source.At present the LED filament is all to need transformer that voltage is become to suitable voltage, increases cost on the one hand, on the other hand, makes the volume of filament can't miniaturization.
The utility model content
The purpose of this utility model is for the deficiency in the above-mentioned background technology, and a kind of column LED filament is provided, and it is wider that this filament can make light be the angle that column irradiates when using a small amount of LED luminescence chip, and have compact conformation, the characteristics that volume is small and exquisite.
The utility model can be achieved through the following technical solutions:
A kind of column LED filament is characterized in that: described column LED filament comprises a support, is fixed on one group on support LED luminescence chip of mutually connecting, is coated on support and the outer one deck photic zone of LED luminescence chip; Described support comprises a substrate and is arranged in two of this substrate two ends and draw electric leg, and two are drawn between electric leg and substrate and connect into strip by insulating part; Described LED luminescence chip is arranged in substrate one side, and the head end of the LED luminescence chip of this group series connection draws electric leg by wire and one of them and be connected, and the tail end of the LED luminescence chip that this group is connected draws electric leg by wire and another and is connected.
Described substrate is provided with at least one boss for clamping, and this boss is protruded and forms to the substrate bilateral symmetry by substrate.
Described substrate and draw electric leg and adopt copper or aluminium or steel to do.
Described photic zone is comprised of silica gel, resin and fluorescent material.
The beneficial effects of the utility model are:
1. because each LED luminescence chip divides, voltage drop is arranged, LED chip series connection by right quantity can be so that the voltage drop on filament be identical with the voltage of input, only need rectifier just can directly supply filament work, and do not need transformer, be conducive to reduce the volume of bulb, reduce production costs;
2. be coated with refrangible photic zone in the outside of LED luminescence chip, the anaclasis that the LED chip of support one side can be sent by suitable refractive index, to cradle back, makes filament form the column light source, reduces the quantity of LED chip, reduces production costs;
3. the fluorescent material in photic zone can be converted into LED light the complex light that more approaches natural daylight, more adapts to user's demand.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of column LED filament described in the utility model, comprise a support, be fixed on the series system of one group on support LED luminescence chip 1-6(routine of mutually connecting), be coated on support and the outer one deck photic zone 1-5 of LED luminescence chip.
Described support comprises a substrate 1-1 and is arranged in two of this substrate two ends and draw electric leg 1-3, and two are drawn positive pole and the negative pole that electric leg connects respectively power supply; Two are drawn between electric leg and substrate by insulating part 1-2(plastic) connect into strip, thus will draw insulation isolation between electric leg and substrate, avoid electric leg of drawing of two ends to be short-circuited.
Described LED luminescence chip is arranged in the substrate one side, and the head end of the LED luminescence chip of this group series connection draws electric leg by wire and one of them and is connected, the tail end of the LED luminescence chip of this group series connection draws electric leg by wire and another and is connected, obviously, two are drawn electric leg and are connected with negative pole with the positive pole of constant-current supply in bulb respectively, thereby working power are provided to the LED luminescence chip.
Described substrate is provided with at least one boss 1-4 for fixture clamping, and this boss is protruded and forms to the substrate bilateral symmetry by a bit of on substrate, described substrate and draw electric leg and adopt metal making, recommend adoption copper or aluminium or steel.
Described photic zone is comprised of silica gel, resin and fluorescent material.
Figure 4 shows that the LED bulb, be provided with 4 column LED filaments 1 in the diffuser 2 of this bulb, be one another in series between each column LED filament, be full of inert gas 3(in diffuser as nitrogen or argon gas or neon etc.), the dissipation of heat that utilizes inert gas that column LED filament is produced is gone out.
Above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that; Its technical scheme that still can put down in writing previous embodiment is modified, perhaps part technical characterictic wherein is equal to replacement, and these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
