Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Fig. 1 is the forward sight three-dimensional exploded view of first embodiment of the invention LEDbulb lamp 100, and this LEDbulb lamp 100 comprises body 10, two light source boards 20, bulb housing 30 and many vertical LED light sources 24.These two light source boards 20 are disposed adjacent and form V-shaped structure, are roughly vertically arranged on the middle part at this body 10 top.These vertical LED light sources 24 are arranged on the top of this body 10, arrange around these two light source boards 20.Be fixed on this body 10 bottom this bulb housing 30, to be located at the top of this body 10, in these two light source boards 20 and these vertical LED light sources 24 are housed in.
Please refer to Fig. 1, each light source board 20 includes rectangle plate shape substrates 21 and multiple LED light source 22.These LED light sources 22 are respectively area source.A side of this substrate 21 is provided with the first light-emitting area 212, and these LED light sources 22 are separately positioned in the first light-emitting area 212 of these substrates 21.A side of the substrate 21 of these two light source boards 20 is disposed adjacent to each other, and makes these two light source boards 20 form V-shaped structure.The adjacent formation obtuse angle of substrate 21 of these two light source boards 20 or right-angle structure.The first light-emitting area 212 on each light source board 20 is separately positioned on the side away from another light source board 20.
Please refer to Fig. 2, one of them light source board 20 is also provided with the second light-emitting area 223 at the opposite side of this first light-emitting area 212.Wherein another light source board 20 is provided with reflective surface 224, and this reflective surface 224 is to should the second light-emitting area 223 arrange.The light part that this second light-emitting area 223 sends shines directly on this bulb housing 30, and a part is reflexed on the sidewall of this bulb housing 30 by this reflective surface 224.Because this second light-emitting area 223 and this corresponding reflective surface 224 arrange at a certain angle, therefore this reflective surface 224 can strengthen the lighting angle of the second light-emitting area 223 on the sidewall of this bulb housing 30.The light that this second light-emitting area 223 and this reflective surface 224 send, the region that the first light-emitting area 212 that compensate for the opposite side of these light source boards 20 cannot be irradiated, illuminates sidewall and the bottom of this bulb housing 30.Lighting angle due to single led light source 22 is generally about 120 degree (according to present technology, even if be packaged into area source, also the lighting angle of LED light source cannot be made to reach 180 degree), therefore set between these two light source boards 20 angle draws after calculating according to the lighting angle of these LED light sources 22.Angle between these two light source boards 20 the scope that can improve and these two the first light-emitting areas 212 be irradiated the sidewall of this bulb housing 30 is set.If this angle angle is close or be greater than 180 degree, then lighting angle will significantly reduce.
Please refer to Fig. 1, these vertical LED light sources 24 are arranged on the top of this body 10, arrange around light source board 20.The Light distribation that these vertical LED light sources 24 send is at the top of bulb housing 30.
During work, the light that the first light-emitting area 212, second light-emitting area 223 on these light source boards 20 sends, and the light of this reflective surface 224 reflection is mainly radiated at sidewall and the bottom of this bulb housing 30.The light that these the vertical LED light sources 24 being arranged on this body 10 top send mainly is radiated at the top of this bulb housing 30, and therefore, this LEDbulb lamp 100 can realize the large angle illumination at sidewall, bottom and top.
In sum, this LEDbulb lamp 100 is these light source boards 20 vertically disposed at the middle part at this body 10 top, by the light that this first light-emitting area 212 of these light source board 20 sides sends, and the Light distribation of this second light-emitting area 223 of opposite side and the formation of this reflective surface 224, make the sidewall of this bulb housing 30 and bottom can realize wide-angle Light distribation, and add the light that these the vertical LED light sources 24 being arranged on this body 10 end face send, make this bulb housing 30 inner side, bottom and top can obtain sufficient illumination, and the embodiment of this large angle illumination is without the need to by welding multiple LED light source in side face, thus it is simple to have technique, be convenient to the advantage manufactured.
In addition, the present invention also provides the LEDbulb lamp of the second embodiment (because difference is less, therefore figure does not show), and the difference of the LEDbulb lamp 100 in itself and first embodiment of the invention is: first, do not arrange the second light-emitting area 223; Secondly, these substrates 21 are made by transparent or semitransparent material, and the light that this two first light-emitting area 212 sends can pass these substrates 21, is radiated on the sidewall of this bulb housing 30.These two substrates 21 form reflective surface respectively on the back side of this first light-emitting area 212, the light that this first light-emitting area 212 sends can be reflected on the sidewall of this bulb housing 30 by this reflective surface, thus the Light distribation angle that this first light-emitting area 212 is formed on this bulb housing 30 sidewall strengthened further, thus whole bulb housing 30 is made to realize wide-angle luminescence.
These are only preferred embodiment of the present invention above, and not in order to limit the present invention, any those skilled in the art, not departing from this programme technical scope, can work as and utilize the technology contents of above-mentioned exposure to be the Equivalent embodiments of equal change as few modifications.In every case for departing from technical solution of the present invention content, according to the technology of the present invention essence to any amendment made for any of the above embodiments, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
