The specific embodiment

Fig. 1 is the three-dimensional exploded view of the utility model the first embodiment integrated LED bulb lamp, this integrated LED bulb lamp 100 comprises body 30, bulb housing 10, a plurality of LED light source 40, drive circuit 50 and column 20, in the top that this bulb housing 10 is located at this body 30 is coated on this column 20.These LED light sources 40 are arranged at the lateral surface of this column 20, and this drive circuit 50 is arranged at the lateral surface of this column 20 and is electrically connected to these LED light sources 40 and this body 30 respectively.

Please refer to Fig. 1, Fig. 2, this this column 20 is lower large little multiaspect stage body structure, and these LED light sources 40 are evenly distributed on the lateral surface of this column 20.This column 20 is two-part structure, this column 20 comprises upper inclined portion 21 and has a down dip portion 22, the top of these upper inclined portion 21 these bulb housings 10 of deflection arranges, the sidewall setting (as shown in Figure 2) of relative this upper inclined portion 21 these bulb housings 10 of deflection of this portion 22 that has a down dip, is equipped with LED light source 40 in this upper inclined portion 21 and this portion 22 that has a down dip.This LED light source 40 having a down dip in portion 22 is by the phosphor powder layer formation face illuminating source (not shown) that is packaged together, to evenly illuminate sidewall and the bottom of this bulb housing 10.The angle of inclination of relative these body 30 end faces of this upper inclined portion 21 is greater than this portion 22 that has a down dip, so that the LED light source on it can evenly illuminate the top of this bulb housing 10.This column 20 is made by Heat Conduction Material, preferred, and this column 20 is made by pottery, glass or plastics.The bottom of this column 20 is provided with slot to make way 23, and the width of this slot to make way 23 is greater than 1/4th of these column 20 external diameters.This drive circuit 50 comprises line layer (not shown) and a plurality of electronic component (not shown), and this line layer is printed on the lateral surface of this column 20.The electronic component integration of this drive circuit 50 is arranged in this slot to make way 23.

Please refer to Fig. 1, Fig. 2, the bottom opening place of this bulb housing 10 is provided with connecting portion (not shown), and this connecting portion (not shown) is connected with the Base Heat of this column 20, so that the heat that these LED light sources 40 are produced is distributed to space outerpace by this bulb housing 10.

In sum, this integrated LED bulb lamp 100 is provided with column 20, in the top that this bulb housing 10 is located at this body 30 is coated on this column 20, these LED light sources 40 are arranged at the lateral surface of this column 20, and this drive circuit 50 is arranged at the lateral surface of this column 20 and is electrically connected to these LED light sources 40 and this body 30 respectively.Because these LED light sources 40 and drive circuit 50 are directly arranged at the lateral surface of this column 20, like this, the column 20 of this integrated LED bulb lamp 100 is integrated by drive circuit 50 and LED light source 40, can save traditional LED substrate and driving PCB plate, and without radiating piece is set again, thus have advantages of simple in structure, be convenient to assembling, reduce costs.In addition, owing to having saved traditional LED substrate, thereby greatly reduce the heat radiation thermal resistance of these LED light sources 40; And because this drive circuit 50 and these LED light sources 40 are arranged at the lateral surface of this column 20, the connecting portion of this bulb housing 10 and this column 20 are thermally coupled, the electronic component of this drive circuit 50 and the heat of these LED light sources 40 generations are delivered on this bulb housing 10 by this column 20, be dispersed into space outerpace, thereby greatly improved the radiating effect of this integrated LED bulb lamp 100.
