Abstract
The utility model discloses a kind of LED lamp source, including Lamp cup, lamp bar, radiator；Lamp bar is connected by radiator with Lamp cup；The quantity of radiator is consistent with the quantity of lamp bar, mutually isolated between each radiator, one cone of above-mentioned multiple radiator common combination formation, and the conical top is plane；Each radiator has a hollow wheel hub, hub outside surface has the first heat sink of multiple arcs, the length that above-mentioned first heat sink extends outwardly gradually increases from top to bottom, lower position is disposed with the second heat sink for being similarly arc in two neighboring first heat sink, and the length that above-mentioned second heat sink extends outwardly gradually increases from top to bottom.The utility model can solve how to improve the technical problem of bulb lamp radiating effect.
Description
Technical field
The utility model is related to a kind of luminous LED lamp source of use LED light bar.
Background technology
Current LED is typically using lamp bead or lamp bar as illuminating part, and wherein lamp bar is wider in the application of bulb lamp field,
It is fin structure to apply the heat spreader structure on bulb lamp at present, and its radiating effect is limited.
Utility model content
The purpose of this utility model is to provide a kind of LED lamp source, and the technology for solving how to improve bulb lamp radiating effect is asked
Topic.
A kind of LED lamp source, including Lamp cup, lamp bar, radiator；Lamp bar is connected by radiator with Lamp cup；The number of radiator
Amount is consistent with the quantity of lamp bar, mutually isolated between each radiator, one circular cone of above-mentioned multiple radiator common combination formation
Shape, the conical top is plane；Each radiator has a hollow wheel hub, and hub outside surface has the first of multiple arcs
Heat sink, the length that above-mentioned first heat sink extends outwardly gradually increases from top to bottom, in two neighboring first heat sink
Lower position is disposed with the second heat sink for being similarly arc, and the length that above-mentioned second heat sink extends outwardly gradually increases from top to bottom
It is long.
First heat sink generally serpentine.
Second heat sink is integrally similarly serpentine.
The entire length ratio of described its entire length of first heat sink and the second heat sink is 3-2:1.
The thickness of first heat sink gradually increases from top to bottom.
The thickness of second heat sink gradually increases from top to bottom.
The beneficial effects of the utility model are：Because radiating piece is arranged at intervals, the installation of former lamp bar is not disturbed so；Due to
Using the heat sink of arc, it has bigger area of dissipation relative to linear heat sink；The length that heat sink extends outwardly
Degree gradually increases from top to bottom, so distributing beneficial to lamp bar heat, it is to avoid from the heat disturbance at radiator heat-dissipation to lamp bar
On；By setting the second heat sink, and it is arranged in the first heat sink lower this ad-hoc location of position, can so increase
Plus the contact area of dissipation with Lamp cup, while extension and the distance of lamp bar, so as to avoid heat being back to lamp bar.
Brief description of the drawings
Fig. 1 is the schematic diagram of LED lamp source；
Fig. 2 is the schematic diagram of radiating piece；
1. Lamp cups, 2. lamp bars, 3. radiators, 31. wheel hubs, 32. first heat sinks, 33. second radiatings in figure
Plate.
Embodiment
It refer to a kind of LED lamp source in Fig. 1 to Fig. 2, figure, including Lamp cup 1, lamp bar 2, radiator 3.The LED lamp source is same
Sample includes other parts, and such as lampshade, lamp socket part because it is prior art, therefore are no longer excessively described.Lamp cup 1 is from resistance
Fire heat conduction PC Lamp cups.
Lamp bar 2 is connected so as to which by the heat transfer in lamp bar 2 to Lamp cup 1, Lamp cup 1 is then by warm by radiator 3 with Lamp cup 1
Outside amount radiating to cup.The quantity of radiator 3 is consistent with the quantity of lamp bar 2, it is mutually isolated between each radiator 3 and for fan
Shape, one cone of the above-mentioned multiple common combination of radiator 3 formation, the conical top is plane, and this is set by such
Sample is beneficial to fit with Lamp cup 1 to realize higher radiating effect.Each radiator 3 has a hollow wheel hub 31, hollow wheel
Hub 31 can reduce the weight of radiator 3, at the same avoid radiator 3 heat up or cool it is too fast, influence miscellaneous part use.
The above-mentioned outer surface of hollow wheel hub 31 has the first heat sink 32 of multiple arcs, preferably arc selection serpentine, above-mentioned first radiating
The length that plate 32 extends outwardly gradually increases from top to bottom, and the thickness of the first heat sink 32 gradually increases from top to bottom；So add
Fast radiation processes avoid heat disturbance simultaneously.Lower position, which is disposed with, in two neighboring first heat sink 32 is similarly arc
Second heat sink 33, preferably arc also select serpentine, and the length and thickness that above-mentioned second heat sink 33 extends outwardly are same from upper
Gradually increase under, in order to reach preferable radiating effect, first its entire length of heat sink 32 is whole with the second heat sink 33
Body length ratio is 3-2:In the range of 1, preferably 2:1.Above-mentioned radiator 3 is in use using good, the radiator intention
From the design of fan blade, obtain preferable using effect by the way that the creative design of fan blade is applied on radiator
Really.
