Description
Technical field
The utility model relates to lighting device, particularly the emitting led filament of biconial full angle.
Background technology
The filament of conventional incandescent generally can be directly luminous by tungsten filament etc. wire form, this class filament ubiquity short, the defect such as power consumption is large of life-span, and generally can only send sodium yellow, color 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.
At present, the application of LED lamp expands gradually, but LED light source generally can only be flat luminous, light source luminescent angle is generally all between 120 ~ 140 °, cannot truly realize stereo luminously, in order to improve rising angle, need install the optics of lens and so on additional, affect lighting effect, can reduce the due energy-saving effect of LED light source.LED filament is set to three-dimensional column construction and can realizes stereo luminously, and can improve to a great extent luminous efficiency.But setting between substrate and the substrate of traditional column structure filament is too tight, can cause like this filament heat too concentrated, bulb central temperature exceeds a lot of and heat than lip temperature and is difficult for deriving, and causes significantly shorten the useful life of LED filament.
Utility model content
The purpose of this utility model is to overcome in the shortcoming of prior art, and a kind of simple in structure, filament long service life, multilayer stereo is luminous and radiating rate the is fast emitting led filament of biconial full angle are provided.
The purpose of this utility model is achieved through the following technical solutions: the emitting led filament of biconial full angle, it comprises lamp body, positive terminal, negative terminal, positive outside wire and negative outside wire, lamp body is semicircular arc structure, one end of lamp body is connected with positive terminal, the other end is connected with negative terminal, many lamp bodies partly without leave upper and lower both sides progressively reduce towards centre, being inverted cone-shaped structure distributes, positive terminal is connected with positive outside wire, and negative terminal is connected with negative outside wire.
Described lamp body comprises substrate, blue-light LED chip, red LED chip and adhesive layer, the curved structure of substrate, blue-light LED chip is alternately connected with red LED chip and is fixed on the lateral surface of substrate, and adhesive layer is coated on the outside of blue-light LED chip and red LED chip.
Described substrate is the aluminium alloy base plate that outside is coated with reflector layer.
Between described substrate and adhesive layer, be also provided with fluorescence coating.
The utlity model has following advantage:
1, LED chip is arranged on the substrate of semicircle arcuation, many lamp bodies partly without leave upper and lower both sides progressively reduce towards centre, be inverted cone-shaped structure and distribute, it is simple in structure.
2, LED chip is fixed on biconial substrate, can realize 360 ° of Omnibearing even ground luminous, and multilayer stereo is luminous, and light-emitting area is large, and luminous efficiency is high, good illumination effect.
3, substrate is the aluminium alloy base plate that outside is coated with reflector layer, ensureing that under the luminous prerequisite of high colour developing, its base board using material makes its radiating effect fast, reduce near the heat accumulation of LED chip, be difficult for forming tropical island effect, the useful life of further having improved LED filament group.
