Summary of the invention

In order to overcome existing paster LED, need to be applied to the thickness that PCB wiring board has not only increased LED, production cost and difficulty of processing have also been increased, main purpose of the present utility model is to provide a kind of modularity paster LED, the constraint that this modularity paster LED is simple in structure, broken away from PCB wiring board, effectively reduce the height of LED, make processing more simple and easy, cost.

Above-mentioned purpose is achieved by the following technical solution:

According to an aspect of the present utility model, the utility model provides a kind of modularity paster LED lamp bar, comprise: the cathode metal wire and the negative pole plain conductor that connect rectifier input, also comprise the cathode metal baseline and the negative pole metal base that connect LED chip and rectifier output end, by cathode metal wire, negative pole plain conductor, cathode metal baseline, the micro-interval of negative pole metal base is parallel arrangement, and on these wires, be arranged at intervals with a plurality of by its horizontal completely coated plastic cement pedestal, this plastic cement pedestal top has one for the storage tank of accommodating LED chip and packaging plastic, this storage tank bottom is exposed in order to connect the part of cathode metal baseline and the negative pole metal base of LED chip electrode, in storage tank, on LED chip face, be also packaged with a photic zone.

Owing to adopting the modularity paster LED of above technical scheme to break away from LED will to be sticked in PCB PCB surface, realize luminous deficiency, cathode metal wire, negative pole plain conductor, cathode metal baseline, negative pole metal base are to parallel arrangement, effectively reduce the height of LED, make that processing is more simple and easy, working (machining) efficiency is higher, effectively reduce production cost, finally make application more perfect.

Above technical scheme can be further improved by following measures:

In some embodiments, cathode metal wire, negative pole plain conductor are laid in respectively to the both sides of cathode metal baseline and negative pole metal base.These two line one end are welded on respectively on rectifier input, and this has just solved the connection rectifier input of pulling strings in addition and has passed through the trouble that whole lamp support brings.

In some embodiments, in order to improve as much as possible light efficiency, reduce the diffuse scattering of LED light source, in exposed cathode metal baseline end, storage tank bottom, be provided with an optically focused groove.

In some embodiments, for the workpiece operation of injection machine, add the efficiency of the note of hurrying up, according to need to and being wrapped on cathode metal wire, negative pole plain conductor, cathode metal baseline, negative pole metal base equidistant spaced apart of plastic cement pedestal of design.

In some embodiments, PPA plastics have advantages of high temperature resistant and fire-retardant and intensity is high and resistance to deformation, so the material of plastic cement pedestal adopts PPA plastics and completes by injection machine injection moulding.

In some embodiments, convenient for plastic cement pedestal is arranged, the one side design of negative pole metal base is had to the extension relative with cathode metal baseline end.

In some embodiments, for the ease of the processing of mould, ensure that LED module has frivolous characteristic, cathode metal wire, negative pole plain conductor, cathode metal baseline, negative pole metal base adopt the metal wire rods such as thin iron, copper, aluminium.In order to guarantee that these thin metal wire rods have good electric conductivity and are not corroded, at these metal wire material surfaces, be provided with an electrodeposited coating.
