The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is the stereogram of the utility model first embodiment wide-angle light emitting LED lamp 100, and this wide-angle light emitting LED lamp 100 comprises that a body 10, three light source boards 20 and a bulb shell 30(are as shown in Figure 2).These three light source boards 20 vertically are arranged on the middle part at these body 10 tops.This bulb shell 30 is located at the top of this body 10, and the bottom of this bulb shell 30 is fixed on the top of this body 10, in these three light source boards 20 are contained in (as Fig. 1 and shown in Figure 3).
Please refer to Fig. 1, this bulb shell 30 is transparent configuration, and it is made by plastics or glass material.Certainly, according to consumer's hobby, this bulb shell 30 also can adopt opaque structure.This body 10 comprises the lamp holder of conventional connection civil power and is arranged on radiating piece on this lamp holder etc.The top 12 of this body 10 is roughly planar structure.
Please refer to Fig. 2, these three light source boards 20 are the straight plate structure of rectangle, and the structure of these light source boards 20 is identical.Each light source board 20 includes a substrate 22 and a plurality of led light source 24.This substrate 22 comprises a light-emitting area 222 and a reflective surface 224.This light-emitting area 222 is arranged on a side of this substrate 22, and these reflective surface 224 parallel these light-emitting areas 222 are arranged on the opposite side of this substrate 22.This light-emitting area 222 is vertically set on the top 12 of this body 10 with this reflective surface 224.These led light sources 24 are arranged on the light-emitting area 222 of this substrate 22, and these led light sources 24 are by the phosphor powder layer (not shown) formation face illuminating source that is packaged together.These three light source boards 20 light-emitting area 222 between any two and reflective surface 224 are the setting that links to each other less than 180 ° of angles, so as to utilize light that a reflective surface 224 on the light source board 20 sends the light-emitting area 222 of another light source board 20 towards this bulb shell 30 with external reflectance.Preferably, a side of these three light source boards 20 all arranges near the middle part at the top 12 of this body 10, make each light source board 20 a sidewall all with an adjacent setting of side of other light sources plate 20.The reflective surface 224 of each light source board 20 successively with the light-emitting area 222 of another light source board 20 with respect to the angle setting that becomes less than 180 °, make 120 ° of angle settings of 20 liang of twenty percents of these three light source boards.
Please refer to Fig. 2, during work, the reflective surface 224 of another light source board 20 that the light that the led light source 24 on the light-emitting area 222 on light source board 20 sends will be adjacent to this bulb shell 30 with external reflectance, because these three light source board 20 equal angles settings in twos, just make and outwards luminous that these three light source boards 20 can be around 360 ° of the central shaft (not shown) of this body 10 make this wide-angle light emitting LED lamp 100 can reach the wide-angle illumination effect more than 270 °.
Certainly, understandable, as long as the adjacent setting of side of side and another light source board 20 of a light source board 20 is arranged, the reflective surface 224 of one of them light source board 20 and the light-emitting area 222 of another light source board 20 are with respect to the angle that becomes less than 180 °, with light that this light-emitting area 222 is sent towards this bulb shell 30 with external reflectance, just can increase the lighting angle of this LED lamp 100.
In sum, this wide-angle light emitting LED lamp 100 is provided with a plurality of light source boards 20, and each light source board 20 comprises substrate 22 and led light source 24, and this substrate 22 comprises light-emitting area 222 and reflective surface 224, and these led light sources 24 are arranged on the light-emitting area 222 of substrate 22.Wherein at least two light source boards 20 adjacent setting of side, and 20 one-tenth of these two light source boards are less than 180 ° of angles, thus the direction reflection of the reflective surface 224 of the light that sends on the light-emitting area 222 with light source board 20 by another light source board 20 beyond the bulb shell 30.Compared with prior art, because the light that the reflective surface 224 on this light source board 20 can send the light-emitting area 222 of another light source board 20 is to external reflectance, light extraction efficiency and the lighting angle of this wide-angle light emitting LED lamp 100 have been promoted, no longer need on each face of three-dimensional bracket, led light source be set, thereby make that wide-angle light emitting LED lamp structure of the present utility model is simpler, assemble advantage more easily.
In addition, in the preferred version, the quantity of this light source board can also be arranged to four or more, and these light source board two twenty percent equal angles arrange, and these light source board angulation sums are 360 °, thereby can increase the brightness of this wide-angle light emitting LED lamp.Further, the led light source of this light source board can also adopt the face illuminating source.This just makes the one side of this light source board need not to arrange the plurality of LEDs light source.
Please refer to Fig. 4, it is depicted as the three-dimensional exploded view of the utility model second embodiment, the difference of this wide-angle light emitting LED lamp 100a and first embodiment is that the reflective surface 224a of each light source board 20a of this LED lamp 100a protrudes out towards the light-emitting area 222a of another light source board 20a and is provided with leaded light section 2242.This leaded light section 2242 protrudes out the bottom that is arranged on this reflective surface 224a.This leaded light section 2242 arranges in obtuse angle with the top 12 of this body 10, and the light that this leaded light section 2242 is used for another light source board 20 is sent is towards the direction reflection away from this body 10.Thereby make the top portion of this wide-angle light emitting LED lamp 100a be furnished with more light, thereby make the whole light of this wide-angle light emitting LED lamp 100a be more evenly distributed.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
