The integrated LED driving light source comprises a circuit board integrating a driving circuit, a plurality of LED light-emitting chips and a heat sink. The LED light-emitting chips are fixed to the heat sink in a mode of matrix arrangement, hollow areas corresponding to the LED light-emitting chips one to one are arranged on the circuit board, the circuit board is fixed to the surface of the heat sink to make the LED light-emitting chips penetrate through the hollow areas to be exposed, the circuit board is etched to form copper bars, the copper bars are conductively connected with the driving circuit, and every two adjacent rows of LED light-emitting chips are welded to different positions of the copper bars through wires to be electrically connected. According to the integrated LED driving light source, by changing the structure of the circuit board, the mode of connection and combination between the LED light-emitting chips is changed, and the service life is prolonged; besides, because the heat sink is arranged at the bottom of the circuit board, the heat dissipation performance of the integrated LED driving light source is improved.
Description
Technical field
The utility model relates to LED light source technical field, is specifically related to a kind of integrated LED driving light source.
Background technology
Have the advantages such as long-life, energy-saving and environmental protection, high efficiency feature due to LED light source, its superior physical attribute is that conventional incandescent, fluorescent lamp etc. are incomparable, and therefore it is more and more subject to people at lighting field and favors.
At present, adopt separately of LED encapsulates more, exactly every LEDs luminescence chip encapsulated separately, produces arbitrary source one by one, and then assembles as required; The single individual LED luminous tube that this mode adopts support to be packaged into is conventionally integrated again, be encapsulated on support by LED chip, again support array is welded on additional PCB substrate and forms and be electrically connected, and the Bonding that the electrical connection of LED chip is and chip chamber direct by chip forms, and the lead key closing process of chip and chip chamber is more complicated, and the electrode of LED chip is more fragile, the direct lead wire bonding of chip chamber easily causes electrode damage.
In view of more than, LED is integration packaging prevailing gradually.Integration packaging be by multiple LED chips according to certain arrangement mode, then carry out integration packaging, what this method encapsulated out is the aggregate of a multi-chip.But after employing integration packaging, plurality of LEDs chip is concentrated on very little area, the thermal resistance between LED chip and fin increases, and this just makes heat dissipation problem more outstanding.In addition, in current integrated Packaging Technology, after the inside chip mode of connection is all used first string and combination, after single branch road series connection, then by the combination of multiple branch circuit parallel connections.The shortcoming of this mode be LED lamp on single branch road in the long-term process using, when single or a few LEDs damage if occur, will cause electric current to distribute uneven, affect the illumination effect of whole light source, accelerated ageing, reduces the life-span.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and the integrated LED driving light source that a kind of heat dispersion is high, the life-span is long is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of integrated LED driving light source, comprise the wiring board that is integrated with drive circuit, multiple LED luminescence chips and radiator, the mode that described LED luminescence chip is arranged with matrix is fixed on radiator, on described wiring board, be provided with and LED luminescence chip vacancy section one to one, wiring board is fixed on spreader surface makes LED luminescence chip penetrate described vacancy section and exposed, described circuit board etching is formed with copper bar, described copper bar conducts and is connected with drive circuit, described adjacent two row LED luminescence chips are electrically connected to realize at the diverse location of copper bar by wire bonds.
Concrete, described radiator is aluminium flake, described wiring board is copper base circuit board.
For improve the adhesion of wiring board and aluminium flake and make wiring board and aluminium flake fully in conjunction with to improve heat dispersion, as improving technical scheme, between described copper base circuit board and aluminium flake, be provided with epoxy resin layer, and be fixedly connected with by hot pressing.
For fear of when mounted, vacancy section periphery is scraped and is damaged LED luminescence chip, and each edge, described vacancy section is provided with certain slope.
The utility model has the following advantages and beneficial effect compared to existing technology:
(1) the utility model passes through to change the structure of wiring board, thereby changes the connection combination between LED luminescence chip, makes the electric current of original multi-chip series connection impact be distributed to multiple parallel circuits, reduces the impact of single LEDs luminescence chip on whole light source; And, by arrange copper bar structure realize parallel circuit mode can wiring board carry out circuit make time in the lump etching complete, need not install in addition, save flow process, cost-saving.
(2) the utility model has improved the heat dispersion of integrated LED driving light source by radiator being set in wiring board bottom, thus improved service life; And directly LED luminescence chip is fixed on radiator so that the two fully contacts, further improve heat dispersion.
(3) the utility model is directly in the circuit board integrated by drive circuit, has changed the deficiency that in conventional art, drive circuit is independently set and takies volume, can directly use 220 volts of civil powers, and integrated level is high, and volume is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment integrated LED driving light source.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but the embodiment that the utility model is created is not limited to this.
As shown in Figure 1, a kind of integrated LED driving light source, comprise the wiring board 2 that is integrated with drive circuit 1, four LED luminescence chips 4 and radiator 3, the mode that LED luminescence chip 4 is arranged with matrix is fixed on radiator 3, on wiring board 2, be provided with and LED luminescence chip 4 vacancy section 5 one to one, wiring board 2 is fixed on radiator 3 surfaces makes LED luminescence chip 4 penetrate vacancy section 5 and exposed, wiring board 2 etchings are formed with copper bar 6, copper bar 6 conducts and is connected with drive circuit 1, adjacent two row LED luminescence chips 4 are electrically connected to realize at the diverse location of copper bar 6 by wire bonds.
Wherein: radiator 3 is aluminium flake, wiring board 2 is copper base circuit board.Between copper base circuit board and aluminium flake, be provided with epoxy resin layer, and be fixedly connected with by hot pressing.Each edge, vacancy section 5 is provided with certain slope.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
