Background technology
The LED lamp along with the progress of optical technology is also controlled gradually on cost, but because there is limitation in the LED encapsulating structure, can not be accomplished omnibearing luminous as incandescent lamp so that have the LED lamp now because the advantages such as energy-conserving and environment-protective are more and more welcome.Want to make the LED lamp to become the market mainstream, just must overcome the little problem of LED lighting angle.
Present technology is that led light source is arranged on the support with three-dimensional surface, and support is installed on the lamp holder top, thereby so that led light source vertically arrange with respect to the lamp holder end face so that the light that led light source sends sends to the direction around the whole lamp.For example Granted publication day is on October 31st, 2012, and the patent No. is that the Chinese utility model patent of 201220060615.X has disclosed a kind of high light efficiency large-angle LED bulb.This high light efficiency large-angle LED bulb comprises basic shell, be positioned at described basic shell bottom lamp holder, be installed on described basic shell inside constant-current supply, be covered in described basic shell top cover plate, be fixed in the diffuser that is cubical heat radiation column, accommodates described heat radiation column and link to each other with described basic shell of described cover plate top, the bottom surface of described heat radiation column is installed on the described cover plate, its lap all posts pcb board, and distributing on the every pcb board is welded with several led chips.Because this big-angle LED lamp need to be welded on led chip on the heat radiation column, in order to increase the brightness of this LED lamp side, need to weld a plurality of led chips in each side of support, this is just so that the structure of this LED lamp is more complicated, increase the cost of light source, and a support need to be set and a plurality of led chip could realize that comprehensive wide-angle is luminous.
The utility model content
In view of this, be necessary to provide a kind of wide-angle light emitting LED lamp simple in structure, easy to assembly.
A kind of wide-angle light emitting LED lamp, comprise body, bulb housing and a plurality of light source board, this bulb housing is located at the top of this body, each light source board includes substrate and is arranged on led light source on this substrate lateral surface, the base of described substrate is fixedly installed on the top of this body, lateral surface on the described substrate and the top of this body arrange in obtuse angle, and described substrate arranges around the axis equal angles of this body.
Compared with prior art, this wide-angle light emitting LED lamp is provided with a plurality of light source boards, each light source board comprises substrate, led light source, and all near the adjacent setting of axis at this body, these substrate lateral surfaces become the obtuse angle setting with the top of this body at the top of these substrates.Compared with prior art, because this led light source is set directly at this substrate lateral surface, and all light source boards all become the obtuse angle setting with the top of this body, just so that the luminous energy that these three light source boards send around top and the sidewall of this bulb housing of covering of 360 ° in the axis of this body, thereby promote the light extraction efficiency of this wide-angle light emitting LED lamp and the angle of bright dipping, need on each face of three-dimensional bracket, led light source be set, thereby so that wide-angle light emitting LED lamp structure of the present utility model is simpler, assemble more easily advantage.

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 exploded view of the utility model wide-angle light emitting LED lamp 100, and this wide-angle light emitting LED lamp 100 comprises a body 10, three light source boards 20 and a bulb housing 30.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.
Please refer to Fig. 1, this bulb housing 30 is transparent configuration, and it is made by plastics or glass material.Can be 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 radiating piece on this lamp holder etc.The top 12 of this body 10 is the circular flat structure.
Please refer to Fig. 1, body 10 tops 12 are provided with three light source boards 20, each light source board 20 includes substrate 22 and is arranged on these substrate 22 lateral surfaces (in Fig. 2, be the side towards this bulb housing 30) on led light source 24, these substrates 22 are up-narrow and down-wide trapezoidal or leg-of-mutton structure, and make by ceramic material.The top of these substrates 22 is all near the adjacent setting of axis (as shown in Figure 1) at this body 10, in twos mutual butt.The bottom of these substrates 22 is fixedly installed on the top 12 of this body 10 by supporting seat 23, this supporting seat 23 is provided with inclination joint face 233, and this joint face 233 is thermally coupled with the medial surface of this substrate 22.The 12 one-tenth obtuse angle settings in top (as shown in Figure 2) of these substrate 22 lateral surfaces and this body 10 become spaced set between all substrates 22.This led light source 24 is arranged on substrate 22 lateral surfaces, and this led light source 24 is similar to place substrate 22 lateral surfaces, is up-narrow and down-wide face illuminating source, and these led light sources 24 are by the phosphor powder layer (not shown) formation face illuminating source that is packaged together.
