The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail.
Fig. 1 is the forward sight three-dimensional exploded view of first embodiment of the invention LED bulb lamp 100, and this LED bulb lamp 100 comprises body 10, two light source boards 20, bulb shell 30 and many vertical led light sources 24.These two light source boards, 20 adjacent settings form V font structure, roughly vertically are arranged on the middle part at these body 10 tops.These vertical led light sources 24 are arranged on the top of this body 10, arrange around these two light source boards 20.These bulb shell 30 bottoms are fixed on this body 10, being located at the top of this body 10, in these two light source boards 20 and these vertical led light sources 24 be housed in.
Please refer to Fig. 1, each light source board 20 includes rectangle sheet substrate 21 and a plurality of led light source 22.These led light sources 22 are respectively area source.A side of this substrate 21 is provided with first light-emitting area 212, and these led light sources 22 are separately positioned on first light-emitting area 212 of these substrates 21.A side setting adjacent one another are of the substrate 21 of these two light source boards 20 makes these two light source boards 20 form V font structure.Substrate 21 adjacent formation obtuse angle or the right-angle structures of these two light source boards 20.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 also is provided with 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 224 pairs of this reflective surfaces should second light-emitting area 223 arrange.The light part that this second light-emitting area 223 is sent shines directly on this bulb shell 30, and a part reflexes on the sidewall of this bulb shell 30 by this reflective surface 224.Because this second light-emitting area 223 and this corresponding reflective surface 224 are arranged to certain included angle, so this reflective surface 224 can strengthen the lighting angle of second light-emitting area 223 on the sidewall of this bulb shell 30.The light that this second light-emitting area 223 and this reflective surface 224 send has remedied 212 zones that can't shine of first light-emitting area of the opposite side of these light source boards 20, illuminates sidewall and the bottom of this bulb shell 30.Because the lighting angle of single led light source 22 is generally about 120 degree (according to present technology, even if be packaged into area source, also can't make the lighting angle of led light source reach 180 degree), so set angle is to draw after calculating according to the lighting angle of these led light sources 22 between these two light source boards 20.Arranging of angle between these two light source boards 20 can improve the scope that these two first light-emitting areas 212 are shone the sidewall of these bulb shells 30.If this angle angle approaches or greater than 180 degree, then lighting angle will reduce significantly.
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 that these vertical led light sources 24 send is distributed in the top of bulb shell 30.
During work, the light of the light that first light-emitting area 212 on these light source boards 20, second light-emitting area 223 are sent and 224 reflections of this reflective surface mainly is radiated at sidewall and the bottom of this bulb shell 30.Be arranged on the top that light that these vertical led light sources 24 on these body 10 tops send mainly is radiated at this bulb shell 30, therefore, this LED bulb lamp 100 can be realized the wide-angle illumination at sidewall, bottom and top.
In sum, this LED bulb lamp 100 is vertically disposed these light source boards 20 at the middle part at these body 10 tops, the light that sends by this first light-emitting area 212 of these light source board 20 1 sides, and the light of this second light-emitting area 223 of opposite side and 224 formation of this reflective surface distributes, make sidewall and the bottom of this bulb shell 30 can realize that wide-angle light distributes, and add the light that these vertical led light sources 24 of being arranged on these body 10 end faces send, make these bulb shell 30 inner side, bottom and top can both obtain sufficient illumination, and the embodiment of this wide-angle illumination need not by welding a plurality of led light sources in the support side, thereby it is simple to have technology, the advantage of being convenient to make.
In addition, the present invention also provides the LED bulb lamp (because difference is less, so figure does not show) of second embodiment, and the difference of the LED bulb lamp 100 in itself and the first embodiment of the invention is: at first, second light-emitting area 223 is not set; Secondly, these substrates 21 are made by transparent or semitransparent material, and the light that this two first light-emitting area 212 is sent can pass these substrates 21, is radiated on the sidewall of this bulb shell 30.These two substrates 21 form reflective surface respectively on the back side of this first light-emitting area 212, the light that this reflective surface can send this first light-emitting area 212 is reflected on the sidewall of this bulb shell 30, thereby this first light-emitting area 212 formed light distribution angle degree on these bulb shell 30 sidewalls is further strengthened, thereby make whole bulb shell 30 realize that wide-angle is luminous.
More than these only are preferred embodiment of the present invention, in order to limiting the present invention, any those skilled in the art can not work as the technology contents that utilizes above-mentioned exposure and do a little change and be the equal equivalent embodiment that changes in not breaking away from this programme technical scope.In every case for breaking away from the technical solution of the present invention content, any modification of above embodiment being made according to the technology of the present invention essence, be equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
