Description

The LED filament of a kind of high colour developing, rapid heat dissipation

Technical field

The utility model relates to a kind of LED filament, particularly the LED filament of a kind of high colour developing, rapid heat dissipation.

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.

Yet 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, and especially, in the more concentrated place of crowd, the familiar lacunas of light source is more obvious; (3) 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.

By LED lamp pearl be arranged on stereochemical structure face, can realize stereo luminous, although LED light source belongs to cold light source, its bulb inside is often provided with transformer or rectifier, when bulb throws light on, easily occur that heat is gathered near LED lamp pearl in a large number, form " tropical island effect ".Meanwhile, the light source absorptivity of stereochemical structure face is larger, causes the colour rendering of light source poor.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, and the LED filament of a kind of high colour developing, rapid heat dissipation is provided, and lamp body is arranged on the heat-radiating substrate with reflector layer, radiating efficiency is high, and through the light of reflector layer reflection, luminous efficiency is high, and 360 ° of light are unobstructed, and light-emitting area is large.

The purpose of this utility model is achieved through the following technical solutions: the LED filament of a kind of high colour developing, rapid heat dissipation, it is characterized in that: it comprises lamp socket, lamp body, positive terminal and negative terminal, the cross section of lamp socket is decussate texture, formation has the lamp body installed surface that adjacent two faces are 90 °, each lamp body installed surface is provided with a plurality of lamp bodies along its vertical direction, and positive terminal and negative terminal divide the two bottom sides that is located at lamp socket;

Described lamp body comprises substrate, LED module and adhesive layer, and the both sides of substrate are provided with LED module, and the surface of substrate and LED module is coated with adhesive layer, and one end of substrate is connected with positive terminal, and the other end is connected with negative terminal.

Described lamp socket comprises heat sink and reflector layer, and reflector layer is divided into the both sides of heat sink.

Described heat sink is aluminium base or copper base.

Described described adhesive layer is yellow fluorescence adhesive layer.

The utlity model has following advantage:

1, lamp body is installed in criss-cross lamp socket side, and lamp body installed surface has reflector layer, both can realize stereo luminous, can pass through optical reflection principle again, promote the luminous efficiency of LDE module, good illumination effect, can form 360 ° of unobstructed illuminations, field of illumination area is large.

2, lamp socket endothecium structure is aluminium base or copper base, and its heat transfer efficiency is high, and near heat lamp body is passed and moves to bottom fast by heat sink, has reduced the heat accumulation of lamp body annex, the tropical island effect that can effectively avoid filament to produce.
