The specific embodiment
Fig. 1 is the cutaway view of LED bulb 100 of the present invention, and this LED bulb 100 comprises bulb housing 10, body 60, heat carrier 20 and a plurality of 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 to by wire 40 with the driver (not shown) in being arranged on 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 this tilting section to the bottom reflection light of 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 by 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.
During 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 saved 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 by 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, from this bulb housing 10, to outside, distribute 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, simplified the structure of lamp body, optimized 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.
