Abstract
The utility model relates to a ceramic strip filament structure, which comprises a filament body, wherein the filament body consists of a ceramic strip, reinforcing ribs are respectively arranged at two ends of the ceramic strip, a wafer mounting part is arranged on a central section between the two ends of the ceramic strip, and a layer of LED wafer is uniformly laid on the outer surface of the central section of the ceramic strip; meanwhile, two ends of the LED wafer are respectively connected with the corresponding reinforcing ribs. The utility model discloses beneficial effect does: the ceramic 96 porcelain is adopted, and the LED wafer ancient crystal is arranged between two ends of the ceramic strip, so that the heat conduction and insulation performance can be improved; reinforcing ribs are added at two ends of the LED wafer filament strip, so that the stability of the support can be enhanced; the LED wafer is arranged on the outer surface of the ceramic strip in a surrounding mode, so that light can be uniformly dispersed to the front surface and the back surface.
Description
Technical field
The utility model relates to LED illumination technology, particularly relates to a kind of ceramic bar filamentray structure.
Background technology
LED silk is common is LED post, and LED light source will reach certain illuminance and illuminating area in the past, need install the optics of lens and so on additional, affect lighting effect, can reduce the due energy-saving effect of LED.Existing filament is mainly classified according to the difference of filament support (substrate) material, has the types such as sapphire, glass, crystalline ceramics, copper wire.
But current filamentray structure also exists very large defect, such as, sapphire transparent degree is high, intensity is high, and intensity is comparatively large according to technique difference difference, and being the material be comparatively early applied on LED silk, is also the material that on market, acceptance is higher.But sapphire cost is higher, current sapphire substrates is substantially all take sapphire tailing to be formed by laser cutting-up, and be also difficult to accomplish volume production except laser is with high costs, the space reduced costs is little.
For another example, also there is same predicament in crystalline ceramics and sapphire, can be more difficult in the control of volume production and cost, but current crystalline ceramics is dry process, certain reduction may be brought to cost after following casting technique developing is got up, substantially alternative sapphire, but in price advantage not obvious.
And for example, glass LED light focuses on heat radiation most, security is lower, service life is also short, although electric current all reduces when use Glass Design by a lot of producer, reduce the generation of heat with this, but fact proved the rated power that does like this except wasting chip and reduce except light efficiency and can not have any improvement to filament heat radiation; Another fatal problem of glass is that side has blue light and spills, affect light efficiency and look aobvious while also human eye is harmful to.
In addition, Copper base material more easily realizes in LED technique, and processing yield is higher, and price is also low simultaneously, but due to its metalline, needs at one end to add insulating point, and metal is light tight so there is shadow.
This case is pointed out for above defect, and the LED silks such as existing glass, copper, pottery can only guarantee the uniform illumination of one side, and light cannot be made to evenly spread to positive and negative two faces; Secondly, heat conduction and the insulating properties of existing ceramic filament are poor; Moreover ceramic filament end lacks the strong point.
Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model provides one to be conducive to improving heat conduction and insulating properties, can strengthen the stability of support, light can be made to evenly spread to the ceramic bar filamentray structure in positive and negative two faces, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of ceramic bar filamentray structure, comprise filament body, described filament body comprises ceramic bar composition and these ceramic bar two ends are respectively with reinforcement, and the central segment between ceramic bar two ends is set to wafer installation place, and this ceramic bar central segment outer surface evenly lays one deck LED wafer; Meanwhile, described LED wafer two ends connect with corresponding reinforcement respectively.
Correspondingly, described filament body is cylinder or cone shape, and the ceramics pole that ceramic bar is ceramic 96 porcelain by model forms;
Each ceramic bar outer end is fixed in fixing housing.
The beneficial effect of ceramic bar filamentray structure described in the utility model is:
(1) adopt ceramic 96 porcelain, then by ancient for LED wafer crystalline substance is arranged between ceramic bar two ends, be conducive to improving heat conduction and insulating properties;
(2) increase reinforcement at LED wafer filament bar two ends, the stability of support can be strengthened;
(3) LED wafer is compassingly set at ceramic bar outer surface, light can be made to evenly spread to positive and negative two faces.

1, ceramic bar; 2, LED wafer; 3, reinforcement; 4, filament body; 5, fixing housing.
Detailed description of the invention
As Figure 1-3, ceramic bar filamentray structure described in the utility model embodiment, comprise filament body 4, the ceramic bar 1 that described filament body 4 is ceramic 96 porcelain by the model of cylinder or cone shape form and these ceramic bar 1 two ends respectively with reinforcement 3, between ceramic bar 1 two ends, be set to wafer installation place, this ceramic bar 1 central segment outer surface evenly lays one deck LED wafer 2 can make light evenly spread to positive and negative two faces; Meanwhile, described LED wafer 2 two ends connect with corresponding reinforcement 3 respectively; In addition, each ceramic bar 1 outer end is fixed in fixing housing 5, is conducive to improving heat conduction and insulating properties, can strengthen the stability of support.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
