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 three-dimensional exploded view of wide-angle light emitting LED lamp 100 of the present invention, and this wide-angle light emitting LED lamp 100 comprises a body 10, three light source boards 20, bulb housing 30 and wiring board 40.These three light source boards 20 roughly vertically are arranged on the middle part at these body 10 tops.This bulb housing 30 is located at the top of this body 10, and the bottom of this bulb housing 30 is fixed on the top of this body 10, in these three light source boards 20 are contained in.This wiring board 40 is arranged on the top of this body 10.
Please refer to Fig. 1, this bulb housing 30 is transparent configuration, and it is made by plastics or glass material.According to Consumer Preferences, this bulb housing 30 also can adopt opaque structure.This body 10 comprises the lamp holder of conventional connection civil power and is arranged on being used on this lamp holder accommodates the plastic etc. of driving.The top 12 of this body 10 is the circular flat structure.
Please refer to Fig. 1, these three light source boards 20 are the straight plate structure of rectangle, made by ceramic material, in twos equal angles setting between these light source boards 20, these light source board 20 angulation sums are 360 °, the adjacent setting of the side of the side of at least one light source board 20 and another light source board 20, and the light-emitting area of the reflective surface of one of them light source board 20 and another light source board 20 is with respect to the angle setting that becomes less than 180 °.The light-emitting area of each light source board 20 is provided with a plurality of led light sources, and these led light sources comprise a plurality of forward led light sources 24 and a side direction led light source 25, and these led light sources are by the phosphor powder layer (not shown) formation face illuminating source that is packaged together.20 are fixed in the groove (not shown) at top 12 by adhesive between these light source boards, and these light source boards 20 are realized being electrically connected by the circuit 42 on the wiring board 40.Each light source board 20 includes a substrate 22, a plurality of forward led light source 24 and a side direction led light source 25.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 (as shown in Figure 1) 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 forward led light sources 24 are arranged on the light-emitting area 222 of this substrate 22 simultaneously with the side direction led light source.This side direction led light source 25 is arranged on the upper end of these forward led light sources 24, is positioned at the top of this light-emitting area 224, more close this bulb housing 30.These forward led light sources 24 and this side direction led light source 25 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 the sidewall of this bulb housing 30 with external reflectance.Preferably, a side of all light source boards 20 all arranges near the middle part at the top 12 of this body 10 so that a side of each light source board 20 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 °, so that 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 forward led light source 24 on the light-emitting area 222 on light source board 20 sends will be adjacent to this bulb housing 30 with external reflectance, and the side direction led light source 25 on light-emitting area 222 is directly luminous to bulb housing 30 directions, because these three in twos equal angles settings of light source board 20, just so that these three light source boards 20 can be outwards luminous around the central shaft omnidirectional of this body 10, this wide-angle light emitting LED lamp 100 covers the overwhelming majority zone of this bulb housing 30, so that can reach the wide-angle illumination effect more than 270 °.
In sum, this wide-angle light emitting LED lamp 100 is provided with a plurality of light source boards 20, each light source board 20 comprises substrate 22, forward led light source 24 and side direction led light source 25, these forward led light sources 24 and side direction led light source 25 are arranged on the light-emitting area 222 of substrate 22, and side direction led light source 25 is towards this bulb housing 30 tops irradiation, accordingly, forward led light source 24 is towards the sidewall irradiation of this bulb housing 30.Compared with prior art, these forward led light sources 24 just can cover the most regional of this bulb housing 30 with the scope of side direction led light source 25 irradiations.Because this light source board 20 and on led light source simple in structure, the institute so that wide-angle light emitting LED lamp of the present invention has advantage simple in structure, easy to assembly.In addition, by at this substrate 22 light-emitting area 222 and reflective surface 224 being set, these forward led light sources 24 and side direction led light source are arranged on the light-emitting area 222 of substrate 22, the side direction led light source is arranged on the direction of more close bulb housing 30, make the adjacent setting of side between two light source boards 20, reflect towards the direction beyond the bulb housing 30 thereby the light that sends on the light-emitting area 222 with light source board 20 passes through the reflective surface 224 of another light source board 20.Like this, can promote the light extraction efficiency of this wide-angle light emitting LED lamp 100 and the angle of bright dipping, need on each face of three-dimensional bracket, led light source be set.
In addition, in the preferred version, the quantity of this light source board can also be arranged to four or more, these light source board two twenty percent equal angles arrange, 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 other face illuminating sources.This is just so that the one side of this light source board need not to arrange the plurality of LEDs light source.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
