Description
Technical field
The utility model relates to lighting field, particularly a kind of wide-angle emitting bulb.
Background technology
In recent years, led chip applies to the room lighting field as light source and is developed fast.Yet, because there is certain limitation in the LED encapsulating structure, make existing led light source can only realize being not more than 180 ° lighting angle and can't as incandescent lamp, accomplish omnibearing luminous.Want to make the bulb can replace incandescent, 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 face, support is installed on the lamp holder top, thereby makes led light source vertically arrange with respect to the lamp holder end face, makes the direction emission around the whole lamp of light that led light source sends.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 wide-angle bulb bubble.This high light efficiency wide-angle bulb steeps lamp holder, the constant-current supply that is installed on described basic shell inside, the cover plate that is covered in described basic shell top that comprises basic shell, is positioned at described basic shell bottom, the diffuser that is cubical heat radiation column, accommodates described heat radiation column and link to each other with described basic shell that is fixed in described cover plate top, wherein, 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 wide-angle bulb need be welded on led chip on the heat radiation column, in order to increase the brightness of this bulb side, need weld a plurality of led chips in each side of support, this just makes that the structure of this bulb is more complicated, and a support need 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 emitting bulb simple in structure.
A kind of wide-angle emitting bulb, comprise body, bulb shell and a plurality of light source board, this bulb clamshell is located at this body end face, the bottom of described light source board is fixed on the end face of this body, wherein at least one light source board is provided with the upright to light-emitting area of deflection bulb shell, should stand to light-emitting area is strip, should be upright to the end face of light-emitting area and this body angle in obtuse angle, this upright to light-emitting area in the bottom of the light source board at the projection of this body end face and its place and the line deflection formation deflection angle at this body end face center.
Compared with prior art, this wide-angle emitting bulb is provided with a plurality of light source boards, each light source board is provided with this and stands to light-emitting area, should be upright to the end face of light-emitting area and this body angle in obtuse angle, this upright projection and the bottom of the light source board at its place and deflection angle of line deflection formation at this body end face center on light-emitting area and this body end face.It so just can be the sidewall that this upright light that sends to light-emitting area is evenly distributed in the top of this bulb shell as far as possible.Because only needing to arrange specific deflection angle and direction just can realize that wide-angle is luminous, makes this wide-angle emitting bulb have advantage of simple structure.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the wide-angle emitting bulb of the utility model first embodiment.
Fig. 2 is that wide-angle emitting bulb shown in Figure 1 is removed overlooking behind the bulb shell.
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 emitting bulb 100, and this wide-angle emitting bulb 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 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 end face 12 of this body 10 is roughly planar structure.The end face 12 of this body 10 is provided with reflector layer.
Please refer to Fig. 1 and 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 ceramic substrate 22 and a plurality of upright to light-emitting area 24.Should uprightly to this bulb shell 30 of light-emitting area 24 deflections (as shown in Figure 1) be set.Should stand to light-emitting area 24 is strip area source structure.Should be upright to the end face 12 of light-emitting area 24 and this body 10 angle (as shown in Figure 1) in obtuse angle, make these uprightly towards the top of this bulb shell 30 (as shown in Figure 2) is set to light-emitting area 24.Should be upright to the line deflection formation deflection angle β (as shown in Figure 2) of the projection of light-emitting area 24 on these body 10 end faces 12 with bottom and this body 10 end faces 12 centers of the light source board 20 at its place, this deflection angle β is in 45 °～180 ° scopes.These light source boards 20 are that center of circle equal angles arranges at interval with the center of these body 10 end faces 12, and the angle sum at interval is 360 ° between these light source boards, as shown in Figure 2.These are upright, and to be provided with light source to light-emitting area 24 luminous to realize, these light sources are a plurality of led light sources, and these led light sources are by the phosphor powder layer formation face illuminating source (as shown in Figures 1 and 2) that is packaged together.
Please refer to Fig. 1, during work, the upright light that sends to light-emitting area 24 on these light source boards 20 will be covered with the space outside this bulb shell 30 as much as possible, make the top of this bulb shell 30 and sidewall all be shone by light.Make this wide-angle emitting bulb 100 can reach the wide-angle illumination effect more than 240 °.
Understandable, except three light source boards 20 are set, four or more light sources plate 20 can also be set, be more evenly distributed with the light that shows this wide-angle emitting bulb 100.In the enforcement, at least one forms this deflection angle β in these light source boards 20, just can increase lighting angle.This substrate 22 also can adopt other materials, as aluminium base etc.
In sum, this wide-angle emitting bulb 100 is provided with a plurality of light source boards 20, each light source board 20 is provided with this and stands to light-emitting area 24, should be upright to the end face 12 of light-emitting area 24 and this body 10 angle in obtuse angle, a deflection angle β of line deflection formation at this upright projection on light-emitting area 24 and these body 10 end faces 12 and bottom and this body 10 end faces 12 centers of the light source board 20 at its place.It so just can be the sidewall that this upright light that sends to light-emitting area 24 is evenly distributed in the top of this bulb shell 30 as far as possible.Compared with prior art, just can realize that wide-angle is luminous owing to only need to arrange specific deflection angle and direction, make this wide-angle emitting bulb 100 have advantage of simple structure.The reflector layer of these body 12 end faces can be with beyond this bulb shell 30 of more light directive.
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.
