Description
Technical field
The present invention relates to the LED bulb that a kind of wide-angle is luminous, belong to LED technology field.
Background technology
One technical problem of LED is: the luminescence of chip is the most direct so that the dispersion effect of lamp body is the best, and then leads
The lighting angle having caused LED bulb is the least.
In order to improve the angle of departure of LED bulb, some prior aries use the mode installing reflecting piece in LED bulb, make
The light that LED chip sends is reflected by reflecting piece, reaches to improve the effect at lamps emission angle.Such as patent document
CN203202726U discloses a kind of Large-angle LED lamp bulb, LED chip both sides are provided with reflector.But due to
The caloric value of LED chip is relatively big, it be arranged around reflector after, cause heat to concentrate on the sky surrounded of reflector
In, it is difficult to distribute, makes the life-span of LED chip be affected.
Summary of the invention
The technical problem to be solved is: add the heat dispersion problem of poor that the LED bulb of reflector exists,
The corresponding construction of its reflector is improved by the present invention.
Technical scheme:
The LED bulb that a kind of wide-angle is luminous, includes lamp holder, heat dissipating housing, LED chip, substrate, and LED chip is arranged
On substrate, being provided with reflector on the substrate of the both sides of LED chip, described reflector is hollow structure, Inner Constitution
Plate inner chamber, is provided with opening at reflector towards the side of LED chip；It is heat dissipation cavity in the lower section of substrate, in heat dissipation cavity and plate
Chamber is connected, and is provided with air pump in heat dissipation cavity.
It is heat-conducting layer below described heat dissipation cavity.
It is additionally provided with fan below described heat-conducting layer.
The material of reflector is the one in aluminium, stainless steel, frosted glass.
The upper end of described opening is provided with blinker, and blinker makes the air-out direction of opening towards LED chip.
The material of described blinker is glass.
Beneficial effect
The LED bulb that the present invention provides can efficiently solve the problem that reflector causes LED chip heat dispersion difference.

Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most identical or
Similar label represents same or similar element or has the element of same or like function.Describe below with reference to accompanying drawing
Embodiment is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.In description of the invention
In, it is to be understood that term " " center ", " longitudinally ", " laterally ", " length ", " width ", " thickness ", " on ", D score,
"front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward ", " clockwise ", " counterclockwise "
It is based on orientation shown in the drawings or position relationship in the orientation indicated or position relationship, is for only for ease of the description present invention and Jian
Change and describe rather than indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and behaviour
Make, be therefore not considered as limiting the invention.
Embodiment 1
The present invention provide LED bulb structure as in figure 2 it is shown, include lamp holder 1, heat dissipating housing 2, LED chip 3, substrate 4,
The top of lamp holder 1 is heat dissipating housing 2, and the upper socket in the outside of heat dissipating housing 2 is lampshade, and LED chip 3 and substrate 4 are arranged
In lampshade, LED chip 3 is arranged on substrate 4, is provided with reflector 5 on the substrate 4 of the both sides of LED chip 3,
Reflector 5 is hollow structure, Inner Constitution plate inner chamber, and the material of reflector 5 is the one in aluminium, stainless steel, frosted glass.
At reflector 5, the side of LED chip 3 is provided with opening 6；Heat dissipation cavity 8 in the lower section of substrate 4, heat dissipation cavity 8 with
Plate intracavity inter-connection, is provided with air pump 7 in heat dissipation cavity 8.
In use, when LED works, power supply makes air pump 7 open simultaneously, and air pump 7 makes the reflector 5 of both sides
Air between plate inner chamber forms flowing, and in flow process, air can flow through the top of LED chip 3, constantly takes away folder
Hot-air between two pieces of reflectors 5, forms thermolysis.
In an other embodiment, being heat-conducting layer 9 below heat dissipation cavity 8, heat-conducting layer 9 can be more effectively by heat dissipation cavity 8
In heat going down, make substrate 4 and LED chip 3 lower the temperature.
In an other embodiment, be additionally provided with fan 10 in the lower section of heat-conducting layer 9, fan 10 can preferably by
Heat on heat-conducting layer 9 distributes quickly.
In an other embodiment, being provided with blinker 11 in the upper end of the opening of reflector 5, blinker 11 makes
The air-out direction of opening 6 is glass towards LED chip 3, the material of blinker 11.When air-out in the opening 6 of reflector 5
Time, blinker 11 can make air-out towards LED chip 3, and this radiating mode is more quick；It addition, blinker 11 due to
It is glass material, then the light that LED chip 3 sends, when through blinker 11, can be reflected by it, when light is through gear
After wind sheet 11, it may occur that to reflector 5 side deviation, so that it may so that light is preferably reflected by reflector 5, it is possible to enter one
Step ground improves the effect making LED light scatter, and the light emitting anger making LED bulb is bigger；Without the refraction of blinker 11,
The light that LED chip 3 sends can penetrate the most directly up, and the dispersion effect of reflector 5 would not be obvious.
