Fig. 2 is the stereogram of a lamp holder, a lampshade, a radiating seat and a light emitting diode of this first preferred embodiment;
Fig. 3 is the cutaway view of second preferred embodiment of LED bulb of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Consult Fig. 1 and Fig. 2, first preferred embodiment of LED bulb of the present invention comprises a lamp holder 1, one and is installed on lampshade 2 on this lamp holder 1, radiating seat 3, at least one light emitting diode 4, and a power control unit 5.
This lampshade 2 comprises an end face 21, a shoulder 22, and most be opened in this end face 21 and this shoulder 22 to discharge orifice 23, through said discharge orifice 23 is shed lampshade 2 inner used heat.
This radiating seat 3 is connected with this lamp holder 1 each other tightly, thereby can be with unnecessary thermal energy conduction to this lamp holder 1, and in addition, this radiating seat 3 is placed in this lampshade 2, does not expose to the outside, therefore solves careless touch of user and hot doubt.
This radiating seat 3 comprises that one supplies installing plate that this light emitting diode 4 installs 31, an extension 32 that connects these installing plate 31 peripheries and extend to this lamp holder 1; Reach one by this installing plate 31 and the medium altitude chamber 33 of extension 32 one common peripheral around definition; This installing plate 31 is welded to one another with this extension 32 and is connected; In this first preferred embodiment, this radiating seat 3 is processed for aluminium material, and this extension 32 is cylindrical.
In this first preferred embodiment, it is one light emitting diode 4 that this LED bulb comprises quantity, and this light emitting diode 4 is installed on the installing plate 31 of this radiating seat 3.
This power control unit 5 is fixed in the medium altitude chamber 33 of this radiating seat 3 through the thermal conductive insulation glue filling; The unnecessary thermal energy transfer that reaches the insulation leakproof and power control unit 5 is distributed is to this radiating seat 3, and to make these power control unit 5 runnings smooth and easy, this power control unit 5 is electrically connected this lamp holder 1 and this light emitting diode 4; Be used to control the power of this light emitting diode 4; Adjust the brightness of this light emitting diode 4, in this first preferred embodiment, adjustable power bracket is between 3 watts to 8 watts; Generally speaking, power is that to be equivalent to power be 60 watts osram lamp for 5 watts light emitting diode 4 emitting brightness.
Know by aforementioned; The unnecessary heat energy that this LED bulb is produced; Except being transmitted to the lampshade 2 along the beam projecting direction via air, can also be via this radiating seat 3 fast and effeciently with unnecessary thermal energy conduction to lamp holder 1, the present invention just has two heat dissipation path altogether.In addition, scald one's hand for fear of the user, this radiating seat 3 does not expose to the outside, therefore solves careless touch of user and hot doubt.
What illustrate further is; This radiating seat 3 is processed for aluminium (Al), and is to use the flat aluminum plate stamping and forming, therefore can select fine aluminium for use but not aluminum alloy material; Processing radiating seat 3 with aluminum alloy material through extrusion or aluminium extruded type compares; This first preferred embodiment uses the flat aluminum plate stamping and forming can promote radiating efficiency 20 to 40 percentages, because of dull and stereotyped aluminium sheet trickle hole of after punching press itself can become big because of calendering, the then attenuation of dull and stereotyped aluminium sheet; And then increase whole surface area, and promoted radiating efficiency.Wherein, this radiating seat 3 comprises that also is positioned at the insulating segment 34 that this extension 32 contacts with this lamp holder 1, and this insulating segment 34 is aluminium oxide (Al
