Description
Technical field
The utility model relates to LED illuminating lamp technical field, refers in particular to a kind of high-power integrated lamp pearl.
Background technology
In the prior art, at the existing two kinds of high-power LED illuminating lamps of LED lighting field, first kind: the LED illuminating lamp is stitched together many single watt lamp pearl, is installed in then on the heat sink.The light of the LED illuminating lamp of this kind structure declines bigger, the heat radiation depend on fully the lamp pearl and heat sink between conduction material, existing on the market its thermal conductivity factor of conduction material preferably is 5.0w/m.k, even select best conduction material for use, the LED illuminating lamp still has bigger light decay, thereby influences its light extraction efficiency.Second kind: the LED illuminating lamp with the crystal integrated series of a plurality of LED on a fin, now generally use aluminium as fin, the LED illuminating lamp of this structure has the risk of dead lamp, because the LED wafer is connected entirely, as long as wherein certain crystal occurs then can having influence on the luminous of whole light fixture unusually, the whole LED illuminating lamp can not be worked.
The utility model content
The purpose of this utility model is to provide a kind of high-power integrated lamp pearl at the deficiencies in the prior art, and it is simple in structure, and cost is low, avoids occurring dead lamp, and heat dispersion is good, improves luminous efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high-power integrated lamp pearl, comprise PCB pedestal, LED crystal, PCB circuit and at least two LED crystallo-luminescence lamp groups, the PCB pedestal is provided with positive source and power cathode, some LED crystal are composed in series a LED branch road, LED crystallo-luminescence lamp group is formed in parallel by at least one LED branch road, LED crystallo-luminescence lamp group is fixed in the PCB pedestal, is parallel with at least one LED lamp group branch road between positive source and the power cathode, and LED lamp group is propped up at least two LED crystallo-luminescences of route lamp group and is composed in series.
Described PCB circuit has the conducting ring that head and the tail connect sealing, and power cathode is electrically connected conducting ring, and an end of LED lamp group branch road is connected in conducting ring, the other end is connected in positive source.
Described LED crystallo-luminescence lamp group is arranged in a sub-LED luminous zone in turn.
Described positive source and power cathode are arranged at the two ends of PCB pedestal respectively.
Described LED crystal selects for use single to be 0.5 watt LED crystal.
Be respectively arranged with the assembling and positioning hole around the described PCB pedestal, the centre of PCB pedestal is provided with some assembling and positioning hole.
The back side of described PCB pedestal is provided with anti-oxidation coating.
Described PCB pedestal is selected the thick copper material of 1.0mm for use, and described PCB circuit is selected 1.0mm copper platinum for use.
The beneficial effect that the utility model has owing to the employing technique scheme: any one LED crystal occurs unusual, it is not luminous unusual LED crystal place LED branch road only to occur, can not have influence on the luminous of whole light fixture, avoid occurring dead lamp, the whole LED illuminating lamp rapid heat dissipation in the course of the work of can not working, sheet material is not yielding; Improve light efficiency 5%-10% than traditional aluminium.

The specific embodiment
A kind of high-power integrated lamp pearl, see shown in Fig. 1 and 2, comprise PCB pedestal 1, LED crystal, PCB circuit 2 and at least two LED crystallo-luminescence lamp groups 3, PCB pedestal 1 is provided with positive source 5 and power cathode 6, some LED crystal are composed in series a LED branch road, LED crystallo-luminescence lamp group 3 is formed in parallel by at least one LED branch road, LED crystallo-luminescence lamp group 3 is fixed in PCB pedestal 1, be parallel with at least one LED lamp group branch road between positive source 5 and the power cathode 6, LED lamp group is propped up at least two LED crystallo-luminescences of route lamp group 3 and is composed in series.
Be respectively arranged with assembling and positioning hole 4 around the PCB pedestal 1, the centre of PCB pedestal 1 is provided with three assembling and positioning holes 4.PCB pedestal 1 adopts location, 7 holes, prevents PCB pedestal 1 bending in the course of the work.
The LED crystal selects for use single to be 0.5 watt LED crystal.PCB pedestal 1 is selected the thick copper material of 1.0mm for use, and described PCB circuit 2 is selected 1.0mm copper platinum for use.The base plate of luminous zone adopts surperficial Chen Jin mode, and the back side of PCB pedestal 1 is provided with anti-oxidation coating.Prevent the copper coin oxidation of PCB pedestal 1 and influence its heat dispersion.
The advantage of the high-power integrated lamp pearl that this is novel is, any one LED crystal occurs unusual, it is not luminous unusual LED crystal place LED branch road only to occur, can not have influence on the luminous of whole light fixture, avoid occurring dead lamp, the whole LED illuminating lamp rapid heat dissipation in the course of the work of can not working, sheet material is not yielding; Improve light efficiency 5%-10% than traditional aluminium.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
