Description

LED bulb

Technical field

The utility model relates to LED lighting field, particularly a kind of LED bulb.

Background technology

LED light source has advantages of that luminous efficiency is high, power saving and the life-span long, therefore its application is more and more extensive.Because LED light source is when luminous, the temperature of himself can raise gradually, in the continuous firing process of lighting device, if the heat that LED light source produces cannot leave in time, will cause this light source assembly damage and affect service life of lighting device.At present, the LED bulb of prior art is generally dispelled the heat by independent radiating piece, and for example Granted publication day is on April 25th, 2012, and the Chinese utility model patent that the patent No. is 201120307527.0 has disclosed a kind of LED lamp bulb radiating structure.This LED lamp bulb radiating structure comprises bulb rack and rack-mount fin, these fin directly contact with the radiator portion of LED lamp body, heat can be delivered on fin, fin distributes radially and is provided with multiple heat radiation through holes, the bottom surface of Lamp cup part is provided with multiple openings that allow fin penetrate, and fin is penetrated fixing by opening.

Although this method can play the effect of heat radiation, but multiple fin need to be set, and Lamp cup part will arrange multiple openings these fin are installed, this just makes this LED lamp weight heavier, and material cost is high, and when user uses, feel is heavier, and this LED lamp assembling process is loaded down with trivial details, complex manufacturing technology, cannot provide production efficiency, is difficult to realize automated production.

Utility model content

In view of this, be necessary to provide a kind of LED bulb of simple in structure and good heat dissipation effect.

The technical solution adopted in the utility model is: a kind of LED bulb, comprise body, bulb housing, heat carrier and LED light source, described LED light source is arranged on this heat carrier, this bulb housing is arranged on top the cover of this body and establishes described LED light source and this heat carrier, this heat carrier is connected with the Base Heat of this bulb housing and forms confined space, this heat carrier and described LED light source are housed in this bulb housing inside, and described LED light source is connected with the actuator electrical being arranged in this body.Described LED light source is arranged on the outside of this confined space.

Compared with prior art, this LED bulb by arranging heat carrier in bulb housing, and this heat carrier is connected with the Base Heat of this bulb housing and forms confined space, LED light source is arranged on this heat carrier simultaneously, therefore the heat that LED light source produces can be delivered to bulb housing by heat carrier, then distributes to outside from bulb housing.Not only perfect heat-dissipating of this LED bulb, and possess simple outward appearance as incandescent lamp, do not need to take up room in addition multiple fin are set as prior art, so have advantages of simple in structure.And, because described LED light source is arranged on the outside of this confined space, make described LED light source needn't pass this confined space with being electrically connected of driver, effectively simplify the manufacture craft of this confined space.

Detailed description of the invention

Fig. 1 is the cutaway view of the utility model LED bulb 100, and this LED bulb 100 comprises bulb housing 10, body 60, heat carrier 20 and multiple LED light source 30.These LED light sources 30 are arranged on this heat carrier 20, and this bulb housing 10 is arranged on top the cover of this body 60 and establishes described LED light source 30 and this heat carrier 20.This heat carrier 20 is connected with the Base Heat of this bulb housing 10 and forms confined space 120, this heat carrier 20 and described LED light source 30 are housed in the inside of this bulb housing 10, and described LED light source 30 is realized and being electrically connected by wire 40 with the driver (not shown) being arranged in this body 10.Described LED light source 30 is arranged on the outside of this confined space 120.

Please refer to Fig. 1, this heat carrier 20 is hollow housing structure, and this heat carrier 20 is one-body molded by transparent or semitransparent material with this bulb housing 10.This heat carrier 20 is column structure, and the bottom of this heat carrier 20 is provided with tilting section, and this heat carrier 20 is connected with this bulb housing 10 by this tilting section.This just makes this heat carrier 20 can utilize the bottom reflection light of this tilting section to bulb housing 10.This heat carrier 20 is the column structure that comprises roof 21 and sidewall 22, described LED light source 30 is distributed in respectively on the roof 21 and sidewall 22 of this heat carrier, this heat carrier 20 is made up of glass material, which is provided with line layer (not shown), described LED light source 30 is directly encapsulated on the lateral wall of this heat carrier 20 away from this bulb housing 10.On this heat carrier 20, be integrally formed with printing opacity scattering material or fluorescent material (not shown).

Please refer to Fig. 1, be provided with one or more high thermal conductivity gas in this confined space 120, described high thermal conductivity gas is nitrogen or inert gas or the two mixture.This LED bulb 100 also comprises gas tube 50, one end of this gas tube 50 is connected on the roof 21 of this heat carrier 20, one end of this gas tube 50 is communicated with this confined space 120, the other end of this gas tube 50 is arranged on outside this confined space 120 and is sealed after inflation, and this gas tube 50 is formed in one with this heat carrier 20.

When work, by be filled with high thermal conductivity gas after vacuumizing in bulb housing 10 from gas tube 50 after, one end of this gas tube 50 is sealed, thereby make to form confined space 120 between heat carrier 20 and this bulb housing 10.Because described LED light source 30 and wire 40 are all arranged on the outside of confined space 120, therefore save the sealing process of wire 40 and bulb housing 10, solve bulb and fallen the electric shock problem of breaking.Aspect heat radiation, because this heat carrier 20 is formed in one with this bulb housing 10, and in this confined space 120, be filled with high thermal conductivity gas, the heat that therefore described LED light source 30 produces can be by being delivered to rapidly bulb housing 10, then distribute to outside from bulb housing 10.Aspect luminous, because described LED light source 30 is distributed in respectively on the roof 21 and sidewall 22 of this heat carrier, and this heat carrier 20 is made up of glass material, on this heat carrier 20, be integrally formed with printing opacity scattering material or fluorescent material, therefore the light that described LED light source 30 sends can be evenly distributed on top, bottom and the sidewall of this bulb housing 10, forms wide-angle luminous.

In sum, this LED bulb 100 is by the interior heat carrier 20 that arranges of bulb housing 10, and this heat carrier 20 is connected with the Base Heat of this bulb housing 10 and forms confined space 120, and utilize gas tube 50 to be filled with high thermal conductivity gas to this confined space 120, and described LED light source 30 is arranged on the roof 21 of this heat carrier 20 and the lateral wall of sidewall 22, therefore the heat that LED light source produces can be by being delivered on this bulb housing 10 by this heat carrier 20 rapidly, distribute to outside from this bulb housing 10 again, there is good heat dispersion, wide-angle can be realized luminous simultaneously.And because described LED light source 30 and wire 40 are all arranged on the outside of confined space 120, therefore saved the sealing process of wire 40 and glass envelope, simplify the structure of lamp body, optimize the security performance of this LED bulb 100, so it is simple in structure that this LED bulb 100 possesses, the advantage that perfect heat-dissipating and lighting angle are large.
