Description

A kind of LED based on FPC
Technical field
This utility model belongs to field of illuminating lamps, is specifically related to a kind of LED based on FPC.
Background technology
LED, namely light emitting diode, its basic structure is one piece of electroluminescent chip of semiconductor material, with on elargol or latex solidified to support, connects chip and circuit board, surrounding epoxy sealing, plays the effect of protection internal core, finally install shell.The anti-seismic performance of LED is good, brightness is high and energy-conservation, is widely used in daily life.
In prior art, the structure of the LED of multifaceted light-emitting typically has two kinds, and one is that LED lamp bead is pasted on circuit boards, and then populated circuit board forms the shape of multifaceted light-emitting;Another kind is LED lamp bead to be pasted on circuit boards, then circuit board group is installed on aluminium workpiece surface, pastes a plastic decorating part in PCB surface.In above two structure, the first assembles inconvenience, need polylith circuit board to carry out splicing to assemble, complex manufacturing, need to weld more than 10 junction points, due to artificial operation level, cause the fault product can be a lot, there is no heat sink material simultaneously, the temperature of LED cannot heat conduction timely out, that causes that the power of LED and brightness can not do is higher, and Simultaneous Stabilization can reduce;Although the second adds heat radiation aluminum component, but due to difficulty of processing and technique, easily making LED all to light, can form dark space, there is hidden danger in the illumination to light fixture,
Producing inconvenience, owing to aluminium workpiece surface is fixed with LED fibre board, wiring board needs, by being attached in the operation of the inwall of aluminum component, to add the complexity of welding simultaneously.Same reliability can reduce, additionally, due to LED circuit board needs to be placed on aluminium workpiece surface, it is therefore desirable to digging out the biggest block space to place LED circuit board at aluminium workpiece surface, same volume, the heat dissipating mass of aluminum component decreases a lot, radiating efficiency decline.
This utility model is studied in problem above, it is provided that a kind of feasible solution.
Utility model content
For deficiency of the prior art, this utility model provides a kind of LED based on FPC, and simple in construction is easy to assembly, perfect heat-dissipating.
This utility model is achieved through the following technical solutions.
A kind of LED based on FPC, including lamp socket, described lamp socket is provided with control circuit plate, and described control circuit plate is connected with FPC, and described FPC is wrapped on radiating piece, and described FPC is disposed with some lateral LED lamp bead;Described FPC and control circuit plate are externally provided with heat-dissipating casing, and described heat-dissipating casing is disposed with the through hole mated with lateral LED lamp bead.
Complicated compared to assembling of the prior art low with radiating efficiency, this utility model uses FPC, its thickness is thinner much than common fibre board, therefore heat transfer is more preferably, heat-conducting effect improves 80%, makes the heat conduction between lateral LED lamp bead and radiating piece apart from shorter, and heat-conducting effect becomes apparent from.
Additionally, due to the feature that FPC can bend, many lamp bead annular layouts can be realized on radiating piece, can reach 360 degree luminous, simple and convenient and cost of manufacture is lower;Production technology is simpler, it is only necessary to FPC and control circuit plate just can be connected by 2 solder joints, reduce the complexity of manual production, improve reliability.
Further, in the application, owing to LED lamp bead is placed on the inside, heat-dissipating casing is exposed, and area of dissipation is more.
As preferably, the top layout of described radiating piece has top LED lamp bead, and described top LED lamp bead is coated with top heat dissipation part, and described top heat dissipation part is provided with the hole mated with top LED lamp bead.This structure is used for top light emitting, and has good radiating effect.
As preferably, described top heat dissipation part is externally provided with top lens, it is ensured that spotlight effect, or the light of top LED is spread out, and forms a ring of light.
As preferably, the thickness of described FPC is 0.1mm, and the thickness than traditional fibre plate 1mm is little a lot.
As preferably, described radiating piece, heat-dissipating casing, top heat dissipation part are alumiaum article, good heat dissipation effect.
Compared with prior art, this utility model has the advantages that and employs the FPC thinner than traditional fibre plate, and adding heat-conducting effect, improve thermal diffusivity, LED lamp bead is easy for installation simultaneously, and overall package is convenient, and reliability is high, and heat radiation is more preferably.
