Description

A kind of simple and easy LED lamp string structure

[technical field]

The utility model relates to a kind of lamp string structure, particularly relates to a kind of simple and easy LED lamp string structure.

[background technology]

Patent Office of State Intellectual Property Office website on August 11st, 2004 a disclosed name be called the utility model patent of " parallel LED lamp string ", the patent No. is ZL 03263542.7, notification number is CN 2632476Y, this patent comprises two interval one first lead 4 and one second lead 5 and a plurality of LED crystal grain 6 side by side, respectively this LED crystal grain 6 has one first electrode 61 and one second electrode 62 that is positioned at opposite end, and each first electrode 61 is electrically to anchor on this first lead 4, second electrode 62 of LED crystal grain 6 is connected with second lead 5 by a metal wire 64, there is certain defective in this spline structure, because crystal grain is very little, directly anchor on the lead insecurely, crystal grain is directly come off from lead; Crystal grain directly is fixed on does not have definite position yet on the lead, the light direction of crystal grain and intergranule is also uncertain, seems disorderly and unsystematic after illumination shoots out; Because the metal wire 64 that is provided with between second electrode 62 of second lead 5 and LED crystal grain 6 is very thin, almost be difficult to see clearly by naked eyes, semi-finished product lamp string before the encapsulation is easy to make metal wire and poor wire connection or directly comes off each other in moving process, not working at interval can appear in the lamp string of making, and the finished product yield that causes producing descends.On April 20th, 2005, State Intellectual Property Office also disclosed the utility model patent that a name is called " LED lamp string structure ", the patent No. is ZL 200420047928.7, notification number is CN 2694096Y, this structure comprises at least by a luminescent wafer and two leads with insulation coating layer, this two lead is to be provided with a platform every a suitable length in a lead wherein, be provided with a luminescent wafer in this platform, this luminescent wafer can imperceptible wire and two leads do electric connection, and being in the sealant covers setting of a transparent material in the setting of this luminescent wafer, this sealing can be with platform, luminescent wafer, wire and the lead that is positioned at this place are coated on wherein.Though this structure has solved the rambling problem that seems after above-mentioned wafer light shines out, but the problem that has above-mentioned wire and poor wire connection equally or directly come off, not working at interval can appear in the lamp string of making, and makes the finished product yield of producing can't reach standard.

[utility model content]

The technical problems to be solved in the utility model provides a kind of sound construction, simple and easy LED lamp string structure that the finished product yield is high.

The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of simple and easy LED lamp string structure, comprise interval first lead and second lead side by side, luminescent wafer that is electrically connected with two leads and the packing colloid that coats luminescent wafer and part lead, it is characterized in that, be interval with first substrate at described first its longitudinal direction of lead upper edge, second lead is provided with second substrate corresponding with described first substrate position, be fixed together by an insulation isolating pad between described first substrate and described second substrate, described luminescent wafer is fixed on first substrate or second substrate, first electrode of described luminescent wafer is electrically connected with first substrate by wire, second electrode of described luminescent wafer is electrically connected with second substrate, and described packing colloid is with first substrate, the insulation isolating pad, second substrate, luminescent wafer, wire and the lead that is positioned at this place are coated on wherein.

The beneficial effects of the utility model are: at interval two leads substrate is being set respectively side by side because this structure adopts, by an insulation isolating pad its two substrates is fixed between substrate and the substrate, luminescent wafer is fixed therein on the substrate, first electrode of described luminescent wafer is electrically connected with first substrate by wire, second electrode, second substrate of described luminescent wafer is electrically connected, because wire is to be electrically connected with lead indirectly, avoided semi-finished product lamp string before encapsulation owing to moving the instability of bringing luminescent wafer and lead conduction property, employing is provided with substrate and also is electrically connected with substrate by the wire of luminescent wafer on lead, the fastness that luminescent wafer is electrically connected with two substrates has been strengthened in design like this, has also improved the yield that manufactures a finished product simultaneously.

Further improvement of the utility model:

Preferably, described luminescent wafer is first electrode and second electrode with opposite end, and described first electrode is close to first substrate, and second electrode is electrically connected with second substrate by a wire.

Preferably, described luminescent wafer is three side-by-side RGB luminescent wafers.
