High colour developing N-type LED filament

Technical field

The utility model relates to a kind of LED filament, particularly relates to a kind of high colour developing N-type 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, power consumption headlight defect 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 existing LED filament has following deficiency: (1) generally can only be flat luminous, light source luminescent angle generally all between 120 ~ 140 °, cannot truly realize stereo luminous; (2) colour rendering of light source is poor, and light decay phenomenon is comparatively serious, the place of especially concentrating crowd, and the familiar lacunas of light source is more obvious; (3) heat dispersion of filament is poor, easily produces tropical island effect, affects the service life of LED bulb; (4) packing forms of traditional LED lamp adopts vertical LED (Lamp-LED), surface mount LED(SMD-LED), side-emitting LED (Side-LED), top light emitting LED(TOP-LED), cover brilliant LED(Flip Chip-LED) etc. mode, all belong to point type encapsulation, its shortcoming is that light sensation is discontinuous, cannot multi-angle, luminous at many levels.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel height colour developing N-type LED filament is provided, and multi-angle, multilayer stereo are luminous, light sensation continuity is good, improves the colour rendering index of white light source, and white-light spectrum composition is abundant, more approach natural daylight, and perfect heat-dissipating.

The purpose of this utility model is achieved through the following technical solutions: high colour developing N-type LED filament, it comprises the first N-type substrate and the second N-type substrate, one end of the first N-type substrate is connected with the second N-type substrate, and the other end is provided with positive outside wire, and positive outside wire is connected with positive terminal; One end of the second N-type substrate is connected with the first N-type substrate, and the other end is provided with negative outside wire, and negative outside wire is connected with negative terminal;

The first described N-type substrate is with the second N-type substrate by three sections of straight substrate compositions that bending is connected mutually, and the both sides of every section of straight substrate are provided with LED illuminating module, and the surface of straight substrate and LED illuminating module is coated with adhesive layer.

The LED illuminating module of described each side includes blue-light LED chip and the red LED chip of multiple mutual series connection.
