Description
Technical field
The utility model relates to a kind of lighting device, particularly a kind of novel LED filament.
Background technology
At present, the wire that the filament of conventional incandescent generally can be directly luminous by tungsten filament etc. forms, and this class filament ubiquity short, the defect such as power consumption is large of life-span, and generally can only send sodium yellow, and colour rendering is poor.Simultaneously, under the guide of the strategy of sustainable development, energy-saving and emission-reduction thought is constantly promoted, country more and more payes attention to lighting energy saving and environmental issue at present, carrying out energetically using LED bulb, along with the development of LED technology, electricity-saving lamp and incandescent lamp will be replaced by LED lamp in the near future, and LED street lamp has extraordinary application prospect in new city illumination.
But, still Shortcomings of existing LED filament: because LED is linear light source, therefore the diffusivity of light is not as good as incandescent lamp.Common LED bulb is all translucent, in order to allow light expansion come and to have installed reflecting plate additional.But owing to will reappearing the radiance of incandescent lamp, translucent is impracticable.For head it off, the filament that code name is LDA4LC has entered developer's sight line, but there is no reflecting plate, and the ductility of light is still inadequate.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the novel LED filament that a kind of radiating rate is fast, light diffusing good and height develops the color is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel LED filament, it comprises installing plate, lamp body, positive outside wire, negative outside wire and heating column, installing plate is fixedly installed on the top of heating column, lamp body is arranged at the uper side surface of installing plate, described lamp body comprises substrate, LED illuminating module and adhesive layer, LED illuminating module is arranged on substrate upside along the length direction of substrate, adhesive layer is coated on the outside of LED illuminating module, positive outside wire is connected with one end of substrate, and negative outside wire is connected with the other end of substrate.
Described substrate is penetrating aluminum oxide substrate.
The upper epidermis of described substrate is also coated with one deck reflector layer.
Described heating column is aluminium alloy column.
The utlity model has following advantage:
1, aluminium alloy column heat-transfer rate is fast, and lamp body is arranged on penetrating aluminum oxide substrate, makes the heat conductivity of light better.
2, LED illuminating module, through the reflector layer reflection of upper surface of base plate, has strengthened the diffusivity of light.
3, effectively improved the colour rendering index of white light source, without obviously light decay phenomenon generation, white-light spectrum composition is abundant, more approaches natural daylight, is almost continuous spectrum, makes this LED filament can be applicable to the colour developing to light source and requires high place.

As shown in Figure 1, a kind of novel LED filament, it comprises installing plate 2, lamp body 3, positive outside wire 4, negative outside wire 5 and heating column 1, installing plate 2 is fixedly installed on the top of heating column 1, lamp body 3 is arranged at the uper side surface of installing plate 2, described lamp body 3 comprises substrate 6, LED illuminating module 7 and adhesive layer 8, LED illuminating module 7 is arranged on substrate 6 upsides along the length direction of substrate 6, LED illuminating module 7 includes blue-light LED chip and the red LED chip of multiple mutual series connection, described adhesive layer 8 is yellow fluorescence adhesive layer, adhesive layer 8 is coated on the outside of LED illuminating module 7, positive outside wire 4 is connected with one end of substrate 6, negative outside wire 5 is connected with the other end of substrate 6.
Further, described substrate 6 is penetrating aluminum oxide substrate, and described heating column 1 is aluminium alloy column, heat radiation performance.
Further, the upper epidermis of described substrate 6 is also coated with one deck reflector layer 9, strengthen the diffusivity of light, effectively improve the colour rendering index of white light source, without obviously light decay phenomenon generation, white-light spectrum composition is abundant, more approaches natural daylight, be almost continuous spectrum, make this LED filament can be applicable to the colour developing to light source and require high place.
The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
