Integral LED bulbTechnical field
The present invention relates to a kind of integral LED bulb.
Background technology
In recent years, developing rapidly with lighting engineering industry, light emitting diode（LED）High brightness, low energy are had with itMany advantages, such as consumption, long service life, environmental protection, it is widely used in all multiple fields of illuminating industry.
With the development of application demand, need more and more high-power lamp bulbs.But as solid light source itselfFeature, the heat that more high-power LED operationally sends is higher.Can the heat that these send derive in time or give outGo, become impact LED bulb luminescent quality and the key factor in life-span.
Existing LED bulb is mainly made up of lamp holder, lamp socket, driver, radiator, LED light source component, diffuser etc.：
A kind of LED bulb is to carry out luminous intensity distribution using light reflection device, and LED light source component is arranged on the side of substrate, substrateOpposite side arranges fin；All of heat can only be radiated by arranging the fin of substrate opposite side, and its shortcoming is scatteredHot area is little, and power cannot do greatly；Total output light flux of LED bulb is low, and reflecting and light distributing light loss is big, overall system efficiencyLow.
Separately there is a kind of LED bulb to be that LED/light source is integrated on a stem stem, be placed in the cell-shell of closing；All of heatAmount can only by closing cell-shell outside stem portion radiated, its shortcoming is that radiating efficiency is extremely low, and LED bulb power cannotDo big, LED bulb entirety light output low it is difficult to meet customer requirement.
The heat dispersion of the LED bulb of prior art is not good enough it is difficult to ensure high-power LED bulb luminescent quality and longevityLife.
Content of the invention
It is an object of the invention to provide a kind of integral LED bulb solves to need very big radiating present in prior artDevice meets whole lamp cooling requirements and baroque problem.
The technical solution of the present invention is：
A kind of integral LED bulb, the light-source chamber including radiator and setting gradually, driving chamber, described light-source chamber is served as reasonsDiffuser and the cavity of radiator formation, radiator is provided with LED light source component, and installation base plate, driving and lamp socket composition driveChamber；
Described radiator is made up of installation base plate and radiator, and the lower end of described radiator is vertically inserted in installation base plateOn, described radiator is uniformly distributed with the central shaft of installation base plate for axle, and has certain interval between radiator, is formed with describedThe central axial outer emitting shape heat dissipation channel one of installation base plate, radiator and diffuser are assembled, and the upper end of radiator is stuck in printing opacityIn cover top groove, described installation base plate rides on the bent angle of diffuser bottom.
Further, described installation base plate has air vent, air vent connection driving chamber and heat dissipation channel one, lamp socket setsThere is the transverse slat of fixed drive, drive perpendicular to transverse slat setting, transverse slat has air-vent, air vent, air-vent connection light-source chamber twoGap between lobe spheroid is collectively forming heat dissipation channel two.
Further, described diffuser is installed on lamp socket, passes through connector or wire is connected between described radiator.
Further, described diffuser is made up of symmetrically arranged two lobe diffusers, the upper and lower end of wherein one lobe diffuserIt is equipped with positioning jack.
Further, described diffuser is made using glass, plastic material, and described lamp socket is aluminum component or heat-conducting plastic part systemBecome.
Further, described LED bulb is candle bulb or ball bubble.
The invention has the beneficial effects as follows：This kind of integral LED bulb, simple and reasonable, novel and unique, and radiating effectGood.The present invention is a kind of important breakthrough and innovation to current LED bubble structure, by the light source luminescent region in LED bulbFinding heat-dissipating space is heat dissipation channel, LED bulb radiating and the luminous two-part structure of LED bulb is carried out organic combination, simultaneouslyBy in the portion's perforate of lamp body upper, middle and lower, being internally formed cross-ventilated passage in lamp body, preferably resolve LED bulb volumeThe problem that little, heat-dissipating space is not enough, extends service life；And low cost, easy to assembly, good looking appearance.

Specific embodiment
Describe the preferred embodiments of the present invention below in conjunction with the accompanying drawings in detail.
Embodiment
A kind of integral LED bulb, including light-source chamber 1 and driving chamber 2, radiator；As shown in figure 1, light-source chamber 1 is divided into twoIndividual hemisphere, each hemisphere is made up of a piece of diffuser 11 and a radiator 3, passes through the positioning on diffuser 11 between two hemisphereJack 6 splices, as shown in Fig. 2 light-source chamber 1 is completed the space left in the middle of rear two lobe spheroids for air circulation；Base is installedPlate 8, driving 4 and lamp socket 9 composition driving chamber 2, two radiators 3 are installed with the central shaft of installation base plate 8 for axle, and seam is left in centreGap constitutes radiator, and installation base plate 8 has the sky between the air-vent 7 opened in the middle part of air vent 10 and lamp socket 9 and two radiators 3Gap forms heat dissipation channel two, and air becomes convection current by heat dissipation channel dimorphism, and the heat driving 4 and radiator 3 is taken to outside bulbPortion is it is ensured that the radiating effect of whole lamp.
This kind of integral LED bulb, radiator 3 is installed on one entirety of formation, diffuser 11 between two panels diffuser 11Bottom snaps fitted on lamp socket 9 again；Radiator is assemblied to form by diffuser 11 and radiator 3, and diffuser is equipped with positioning about 11Jack 6, radiator 3 upper end is installed in diffuser 11 groove, and radiator 3 is transversely lapped on diffuser 11 lower end bent angle；Radiator 3It is provided with LED light source component 5；Pass through connector between radiator 3 or wire is connected.
Diffuser 11 is installed on lamp socket 9, as shown in Figure 3.It is provided with driving 4, the transverse slat of lamp socket 9 lower end has in lamp socket 9Air-vent 7, also has air vent 10 in the middle of installation base plate 8, the space composition in the middle of air-vent 7, air vent 10 and radiator 3 dissipatesThe passage of heat two.After bulb is lighted, air can become convection current by heat dissipation channel dimorphism, will drive generation on 4 and radiator 3Heat takes to outside bulb.
Another kind of improvement of the present embodiment is to be also provided with rgb light source control circuit on radiator 3.
