Although this flexible LED SMD lamp belt plasticity is strong, the heat that in light bar, LED sends cannot be distributed by effective heat dissipation path, and LED performance and stability are reduced.
Utility model content
In view of this, be necessary a kind of flexible LED light source of good heat dissipation effect is provided and uses the light fixture of this light source.
The technical solution adopted in the utility model is: a kind of flexible LED light source, comprise LED light source and flexible base board, this flexible base board is provided with conducting wire, described conducting wire is provided with LED land, the electrode of described LED light source is electrically connected with described LED land, described LED light source realizes connection in series-parallel by the arrangement of described conducting wire and connects, and in described conducting wire, at least one part of extending outside this flexible base board forms heat transfer part.
A kind of light fixture, comprise lampshade and flexible LED light source, this flexible LED light source comprises LED light source and flexible base board, this flexible base board is provided with conducting wire, described conducting wire is provided with LED land, the electrode of described LED light source is electrically connected with described LED land, and described LED light source realizes connection in series-parallel by the arrangement of described conducting wire and connects, in described conducting wire, at least one part of extending outside this flexible base board forms heat transfer part, and this flexible LED light source is arranged on this lampshade.
Compared with prior art, this flexible LED light source is provided with conducting wire on flexible substrates, and to make in this conducting wire at least one to extend outside this flexible base board, this conducting wire part of stretching out outside this flexible base board becomes the heat transfer part of this conducting wire, therefore the heat that the LED on this flexible base board sends can be passed with the form such as heat trnasfer, heat radiation by this heat transfer part, thus improves the heat dispersion of this flexible LED light source.Therefore this flexible LED light source not only can bend, and heat dispersion is high, has good heat dissipation effect, advantage that plasticity is strong.

Detailed description of the invention
Fig. 1 is the front view of the utility model flexible LED light source 100 first embodiment, this flexible LED light source 100 comprises flexible base board 10 and multiple LED light source 30, this flexible base board 10 is provided with conducting wire 20, this conducting wire 20 is provided with LED land (not shown), the electrode (not shown) of these LED light sources 30 is electrically connected with LED land, and these LED light sources 30 realize electrical connection in parallel by the arrangement of this conducting wire 20.
Please refer to Fig. 1, this conducting wire 20 comprises two spaced wires 21, each LED land includes the first leg (not shown) and the second leg (not shown) that are disposed adjacent respectively on these two wires 21, and the both positive and negative polarity of these LED light sources 30 welds with the second leg with the first leg of each LED land respectively.These LED light sources 30 can be fixed on LED land by Reflow Soldering, laser weld, eutectic weldering or the mode of electrified regulation.Also comprise two heat transfer parts 40, this heat transfer part 40 is respectively these two wires 21 and extends part outside this flexible base board 10.Also be provided with radiating part (not shown) outside this flexible base board 10, this heat transfer part 40 by insulating heat-conduction material and this radiating part thermally coupled.
Also comprise encapsulated layer (not shown), this encapsulated layer is made up of insulating materials, and this encapsulated layer comprises fluorescent material.The conducting wire 20 that this encapsulated layer covers these LED light sources 30 and is positioned on this flexible base board 10, to play the effect of these LED light sources 30 of protection and these conducting wires 20.
Please refer to Fig. 1, this flexible base board 10 is made up of flexible and transparent insulating materials.This flexible base board 10 should have the features such as certain soldering resistance, frivolous, mechanical strength.This flexible base board 10 adopts transparent polyester class film, such as Merlon (PC), polymethyl methacrylate (PMMA) etc.These conducting wires 20 are printed on this flexible base board 10 by conductive silver paste (not shown).By the conductive filler of nano-silver thread as conductive silver paste, on this flexible base board 10, print thickness is less than the circuit of 0.1mm thus obtains bent electrically conducting transparent circuit 20, thus makes this flexible base board 10 and conducting wire 20 have stronger plasticity.
Please refer to Fig. 2, Fig. 2 is the schematic diagram of the light fixture 200 using the utility model flexible LED light source 100, and this light fixture 200 comprises lampshade 50 and four above-mentioned flexible LED light sources 100, and these flexible LED light sources 100 are arranged on this lampshade 50.Also comprise radiator (not shown), the heat transfer part 40 on these flexible LED light sources 100 connects this radiator by insulating cement.
