Brief description
Fig. 1 is the structural representation of the radiator structure of a kind of bulb lamp tool of a kind of embodiment of the present utility model；
Fig. 2 is that the structure of the radiator of the radiator structure of a kind of bulb lamp tool of a kind of embodiment of the present utility model is shown
It is intended to.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in more detail.
As it is shown in figure 1, the radiator structure of a kind of bulb lamp tool, lampshade the 1st, LED light source the 2nd, radiator the 3rd, lamp holder connection base 4 and
Lamp holder 5；Lamp holder 5 is flexibly connected radiator 3 by lamp holder connection base 4, and lamp holder 5 is helical form or snap, lamp holder 5 and lamp holder
Connect and connected by spiral way between seat 4, be also screw joining manner between lamp holder connection base 4 and radiator 3；In Fig. 2
Shown in, radiator 3 is frustum, and wherein, radiator 3 is little with the connection end diameter of lamp holder connection base 4, the connection end with lampshade 1
Portion's diameter is big；Radiator 3 lower end is provided with LED light source 2, and LED light source 2 passes through screw or glue fixing connection radiator 3 lower end.
Lampshade 1 includes the cloche 11 of hemisphere shape and the connection end 12 of cloche 11 one, and the diameter connecting end 12 is little
In the diameter of cloche 11 opening part, wherein, cloche 11 is all-transparent or translucent setting, the connection end 12 of lampshade 1 with dissipate
Hot body 3 bottom spiral connects, and lampshade 1 leaves air inlet 6 with the junction border of radiator 3, and cold air is from cloche 11
I.e. enter in air inlet 6 after being above heated, and from radiator 3, carry out radiating treatment；Radiator 3 includes the middle part cavity of column
31st, being distributed in fin 32 and the heat dissipating housing 33 of middle part cavity 31 surrounding, middle part cavity 31 is used for installing electric wire or other elements
Material, heat dissipating housing 33 is sheathed on outside the cavity 31 of middle part, and is respectively welded by fin 32 or one-body molded affixed middle part cavity
31 and heat dissipating housing 33 on, radiator 3 is divided into several heat-dissipating cavities by fin 32, each heat-dissipating cavity have heat radiation gas port 34
With gas outlet 35, heat radiation gas port 34 is connected with air inlet 6, therefore, after hot gas enters from air inlet 6, then passes through heat transmission gas
Dispelling the heat in mouth 34, area of dissipation increases.
The radiator structure of a kind of bulb lamp provided by the utility model tool, simple in construction, easy to use, overcome in the past
The shortcoming that bulb lamp heat radiation is dispelled the heat only along spherome surface, the double-deck hollow out radiator structure of employing, energy increasing heat radiation area, and
The gas flow rate of cover surface can be accelerated so that radiating effect is more preferable, improve reliability and the life-span of LED, use and more pacify
Entirely.
The above is only preferred embodiment of the present utility model, it is noted that to those skilled in the art,
On the premise of creating design without departing from the utility model, can also make some similar deformation and improvement, these also should regard
Within protection domain of the present utility model.
