Abstract
The invention discloses an LED module and lamp splicing structure. The LED module and lamp splicing structure comprises LED module battens and a lamp panel which are assembled together; the LED module and lamp splicing structure is characterized in that a graphene layer is arranged between the LED module battens and the lamp panel which are connected, wherein the graphene layer is prepared from a mixture of resin and graphene particles, or is a graphene sheet with the thickness larger than 0.1 mm or is in a multilayered structure.

Meanwhile, materials such as resin and the like with high probability of thermal aging are reduced or avoided, so that the overall service life of the lamp is effectively prolonged.
Description
Technical field
The present invention relates to LED lamp technical field of heat dissipation, particularly relate to a kind of LED module and light fixture split structure.
Background technology
Usually a gap hindering heat to derive to lamp panel is there is in the modular stripe board of LED and light fixture junction.This gap technical finesse heat conductive silica gel routinely in the industry, its defect is: work under the weather colded and heat succeed each other out of doors, heat conductive silica gel in LED lamp can spongeization, dry gradually after about one year, and having a strong impact on heat has module to the derivation of lamp panel, causes early stage light decay.In order to address this problem, the method that each world-renowned manufacturer adopts makees the light fixture of high precision plane, to reduce gap.But due to the characteristic of expanding with heat and contract with cold, the coupling of bi-material can strengthen the invasion and attack of gap and moisture along with long work, causes heat conductive silica gel to be oxidized, makes thermal conductivity decline.At this moment, great power LED obviously can strengthen light decay.For this reason, the most important thing of LED module mounting technique when eliminating the heat conduction obstacle in gap.
Summary of the invention
The object of the present invention is to provide LED module and the light fixture split structure of good heat dissipation effect, long service life.
For reaching above object, the present invention adopts following technical scheme.
LED module and light fixture split structure, comprise the LED module batten and lamp panel that fit together, it is characterized in that, the LED module batten centre that to connect with lamp panel is provided with graphene layer.
Further illustrating as such scheme, described graphene layer is sandwich construction, comprising: the upper strata be folded to form by same graphene film, lower floor, and the elastic layer between the upper and lower.
Further illustrating as such scheme, described elastic layer is graphene layer.
Further illustrating as such scheme, described elastic layer is made up of gold, silver, copper or aluminum.
Further illustrating as such scheme, is provided with pole in the fold position of the upper and lower, and graphene film is folded in half into upper and lower layer along pole outer surface, makes the transition junction of the upper and lower in the arc-shaped.
Further illustrating as such scheme, described graphene layer is the graphene film of thickness between 0.1mm-10mm.
Further illustrating as such scheme, described graphene layer is mixed by the resin-oatmeal of 5% and the micron order Graphene particle of 95%.
Further illustrating as such scheme, is fixed by screw between LED module batten and lamp panel.
Compared with prior art, the invention has the beneficial effects as follows:
One, adopt a graphene film and amount to, the advantage making full use of graphene film plane thermal conductivity efficiency high carries out heat conduction, greatly reduces the thermal contact resistance between LED module and light fixture.Meanwhile, owing to not adopting the easy heat ageing materials such as resin, the whole service life of light fixture is effectively extended.
Two, by increasing one deck elastic layer between upper and lower layer graphene sheet, even if LED module is more coarse with the contact surface of lamp panel, the deformation that also can make full use of graphene film and elastic layer reaches the filling to gap, and thermal contact resistance is effectively controlled.
Three, by placing a pole in the corner of two-layer graphene film, making turning in the arc-shaped, thus avoiding corner defects, be beneficial to heat and distribute.
