Description

The all-round emitting led bulb of Curved surface heterotype

Technical field

The utility model relates to a kind of LED bulb, is specifically related to the all-round emitting led bulb of a kind of Curved surface heterotype.

Background technology

There is directive property light that a lot of bulb adopts various reflective surface LED to send at present to reach all-round light, but in fact filament light-emitting is from all directions, LED is also that identical meeting becomes directive property only because the reason of encapsulation in fact, if current LED silk is exactly that 360 degree of luminescences are as filament, just she be the straight position that cannot bend installing also cannot photoreception as certain in filament different from filament, and to there is a large amount of quality problems the present invention of the too poor grade of heat radiation in LED silk solve to dispel the heat and the problem of light type always.

Utility model content

For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Curved surface heterotype all-round emitting led bulb, can maintain effective heat exchange and cross the heat radiation of high maintenance bulb system to ensure due life-span and light efficiency to avoid LED chip temperature.

In order to realize above-mentioned target, the utility model adopts following technical scheme:

The all-round emitting led bulb of Curved surface heterotype, is characterized in that, comprise substrate, stem, LED chip and bulb shell; Described substrate is made up of two annular module and strip-type module; Described strip-type module connects one end of two annular module lie farthest away; Described LED chip is evenly fixed in annular module by fluorescent glue mixture; The center of described substrate is connected with stem.

The all-round emitting led bulb of aforesaid Curved surface heterotype, is characterized in that, described fluorescent glue mixture is mixed by silica gel and fluorescent material; The edge of described substrate does not all cover fluorescent glue mixture.

The all-round emitting led bulb of aforesaid Curved surface heterotype, is characterized in that, described substrate adopts the glass or crystalline ceramics or sapphire that comprise film plating layer or the heat-conducting metal having hole.

The all-round emitting led bulb of aforesaid Curved surface heterotype, is characterized in that, in described annular module, cover has transparent mist pipe.

The all-round emitting led bulb of aforesaid Curved surface heterotype, it is characterized in that, the gas in described bulb shell is made up of inert gas.

The all-round emitting led bulb of aforesaid Curved surface heterotype, is characterized in that, the number of described substrate is not less than 1.

The beneficial effect that the utility model reaches: electric energy is converted into luminous energy and heat energy when LED chip is lighted, light transmission excitated fluorescent powder mixes out required illumination to all the winds, heat energy is then diffused rapidly to whole substrate surface via base material, form stack effect and increase air velocity, effective exchange area is provided.Chip is placed in helium not easily can maintain the long-life by aging quick heat radiating.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.

The all-round emitting led bulb of a kind of Curved surface heterotype that the utility model relates to, comprises substrate 1, stem 4, LED chip 7 and bulb shell 5.

Substrate 1 is made up of two annular module 2 and strip-type module 3, and strip-type module 3 connects one end of two annular module 2 lie farthest away, as shown in Figure 1.The center of substrate 1 is connected with stem 4.Substrate 1 adopts the glass or crystalline ceramics or semitransparent ceramics or sapphire that comprise film plating layer or the heat-conducting metal having hole, and these materials have concurrently transparent and lead thermal property.

Electrode is made in LED chip 7 both sides, evenly be fixed in annular module 2 by fluorescent glue mixture 6 successively and form connection in series-parallel loop, re-use fluorescent glue mixture 6 and send required assorted light by covering with side above chip, be white light as blue chip adds bloom, it is warm white that blue chip adds yellowish green pink powder, and it is pansy that blue chip adds rouge and powder.When being coated with emphasis be base material need be greater than coating colloid can contact with peripheral gas to retain a large amount of base material, when LED lights, electric energy is converted into luminous energy and heat energy, light transmission fluorescence excitation glue mixture by required illumination to all the winds, heat is then diffused rapidly to whole substrate surface via base material, provides effective exchange area.Here fluorescent glue mixture 6 is mixed by silica gel and fluorescent material.

Annular module 2 part of the substrate 1 processed is put transparent mist pipe, makes the luminous energy that sends evenly mixed, and make it become the condition of a stack effect, be installed on and stem 4 connects wire become loop.

Again its sealing is extracted air in glass shell, filling heat-conductive gas, thermal conductivity gas selects the inert gas of high efficiency and heat radiation, and as helium, the gas in embodiment in bulb shell 5 is made up of pure helium.

Light-emitting area meeting of the present utility model like this and tengsten lamp are closely, because traffic control is bilateral is open therefore can produce cold and hot thermal convection current when producing heat, this can cross outside pipe according to stack effect velocity in pipes soon, add that base material has enough areas to be open not solid by rubber seal, therefore heat can be taken fast to tube face exchange dissipation, maintain the reasonable working temperature of chip.

Because luminescence identical with osram lamp position installed by S type substrate 1 is also 360 degree, therefore immediate lighting kenel can be obtained, due to not enough by substrate 1 area that glue is coated, being taken away rapidly the cell-shell of chip via sealing via heat under the Rapid Circulation of high thermal conductivity gas and the help of stack effect exchanges in outside air, in the helium that chip is placed in one in bulb, without other materials except helium, therefore chip is not easily aging maintains the long-life.

The number of substrate 1 is not less than 1, as the embodiment of Fig. 3 and 4 to be substrate number be respectively 1 and 2.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
