Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
The development of flexible board and pcb board, the raising of the related process levels such as pressing, for the development of Rigid Flex provides good opportunity.Flexible and hard combined circuit board possesses the characteristic of flexible board and pcb board simultaneously, and existing certain flexure region, also has certain rigid region, therefore, it may be used for the products that some have particular/special requirement, to saving interiors of products space, reduce finished-product volume, enhance product performance and be very helpful.FPC is light, small and exquisite, flexible, and repeated flex still can keep electrical property 1,000,000 times, so Rigid Flex can substitute connector, greatly reduces tie point, or changes the position of connector.
Consult shown in Fig. 1, it is the structural representation of the utility model LED flexible and hard combined circuit board, comprise the hard substrate of rigidity 1 and flexible soft base plate 2, the hard substrate of rigidity adopts high thermal conductivity aluminum matrix material, flexible soft base plate 2 is M shape, two pieces of hard substrates of rigidity 1 are connected to the two ends of flexible soft base plate 2 by epoxy glue pressing, two pieces of hard substrates 1 of rigidity are parallel to each other.The hard substrate of rigidity 1 and flexible soft base plate 2 have possessed the endurance of aluminium base and good heat-conducting effect after process for pressing, also have the flexibility of soft base plate and the flexibility of assembling simultaneously.LED group laid by the hard substrate of first rigidity, and LED group receives drive circuit by the connector 3 that the hard substrate of the second rigidity is arranged, and is fixed on irregular support and is connected with the dc source of outside or AC power, avoid the difficulty of structural design.The utility model can be applicable in the systems such as such as automotive lighting, street lighting or Landscape Lighting.
As further improvement of the utility model, LED group is made up of the LED of 3 series connection.Consult shown in Fig. 2, be shown as the circuit theory schematic diagram of the utility model LED group, LED strip joint group comprises LED1, LED2, LED3, and the input/output terminal of 3 LEDs groups receives drive circuit by connector 3.
In sum, the hard substrate of rigidity of the present utility model and flexible soft base plate have possessed the endurance of aluminium base and good heat-conducting effect after process for pressing, also have the flexibility of soft base plate and the flexibility of assembling simultaneously.Be applied on automobile lamp, good heat radiating environment can be provided to LED on the one hand, improve LED radiating condition, improve LED luminous efficiency, promote the dependability of LED, increase the service life.Solve car light space constraints on the other hand, be convenient to the shape-designing of Vehicle lamp structure diversification, optimize car light assembly technology.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
