In various electronic products, some LED element needs paster to be welded on the electronic circuit board, and will realize lateral emitting, for example, and cell phone keyboard, various household electrical appliances panel ledss etc.Adopt common ready-made paster LED element that a weak point is all arranged: the luminous point of LED element is lower, can't satisfy the application of higher luminous point.The LED element of lateral emitting encapsulating structure is convenient realizes this function, and can accurately locate and control out optical position, helps industrialized mass production.Because the electronic product Surface Mounting Technology is a kind of trend of present electron trade, and many electronic circuit boards often adopt SMD welding manner, improves speed of welding and practice thrift cost again, help the multilayer wiring of pcb board, and can reduce the volume that takes up room.So the adopting surface mounted LED element of lateral emitting encapsulating structure has the space, very big market.Market also has the leaded light post that adopts the luminous paster LED element in front and be used to change light direction to realize the paster LED product of lateral emitting abroad.But its cost is high, and assembly technology is complicated, and the patent applied for protection.
The another one aspect, the LED element extensive use of common encapsulating structure and with low cost, element buying source is extensive.Using the LED element of common encapsulating structure to realize lateral emitting and Surface Mounting Technology, also is the technical barrier that needs of industry solve.
Summary of the invention
Therefore, just be based on the deficiency and the problem needs of above-mentioned 2 aspects, the applicant proposes a kind of plug-in type LED is converted into through a modular construction can be applied to paster welded type circuit board, again the higher a kind of LED assembly of LED lateral emitting and luminous point.
The present invention adopts following technical scheme:
A kind of LED assembly comprises at least:
One base, this base possess 1 draw-in groove that is arranged at front end and 2 slots that are arranged at the rear end at least;
One plug-in type light-emitting diode (LED); Side surface direction is inserted and is arranged at above-mentioned base, and its cap body portion is stuck in the draw-in groove of base, and is gripped by before and after the draw-in groove of base; Its pin part is keyed in the slot of base respectively, and is gripped by the slot of base;
One elastic metallic contact member; The bonding pad part and 2 elastic contact blade parts that extend to the upper end that comprise the bottom surface; This elastic metallic contact member one is embedded in the above-mentioned base; The bonding pad of its bottom surface partly exposes the bottom surface of base, and its elastic contact blade part that extends to the upper end is in respectively in the slot of base, and closely contacts with the pin part of plug-in type LED in the slot.
Further, described LED assembly comprises that also one draws lid, is covered on above-mentioned base.
Further, described draw-in groove is consistent with the profile of described plug-in type LED.
Modal, described draw-in groove is an arc-shaped slot, and " U " type groove particularly is to be applicable to the profile of columniform plug-in type LED.
The present invention adopts as above technical scheme, through the modular construction of above-mentioned base, elastic metallic contact member, loam cake, plug-in type LED element is converted into the LED assembly that can be applied to paster welded type circuit board.And this LED assembly is realized lateral emitting, again because its luminous point is higher after increasing base.In addition; The bonding pad of LED unitized substructure secure of the present invention, elastic metallic contact member is partially stabilized reliably, smooth smoothly to be easy to welding and the smooth manipulator that helps of loam cake is drawn this LED assembly, and is welded on the paster welded type circuit board through reflow soldering process.
