Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
With reference to Fig. 1-4, present embodiments provide a kind of all-round smooth LED bulb, including: lens 1, light source board 2 and lamp holder 3；
The left surface of described light source board 2 and right flank have been sticked LED light source 21, and the bottom of light source board 2 has a connection end
22, described connection end 22 electrically connects with lamp holder 3；
The corresponding described LED light source 21 of described lens 1 is fixed on this light source board 2, and described lens 1 include being arranged on LED light
Reflecting surface 11 above source 21 and be connected to two planes of refraction 12 of these reflecting surface 11 both sides；The part light that LED light source 21 sends
Line is respectively facing described plane of refraction 12 by described reflecting surface 11 and reflects and penetrate to outside after plane of refraction 12.Therefore, in employing
Stating after arranging, the lighting angle of LED light source 21 is greatly increased.
In the present embodiment, described reflecting surface 11 is further disposed at the surface of described LED light source 21, described reflecting surface 11
For being gradually distance from the cambered surface of described LED light source 21 in the middle part of it to both sides.Reflecting surface 11 is symmetrical along the axis of symmetry of LED light source 21
Distribution, described reflecting surface 11 is roughly the same, therefore at the luminous flux received by the axis of symmetry both sides along described LED light source 21
The light-out effect ratio of described reflecting surface 11 is more uniform.
Described light source board 2 is curved, and the width of described light source board 2 tapers off to upper and lower two ends from middle part trend, on the left of it
Face and right flank are respectively equipped with many described LED light sources 21, and described LED light source 21 is spaced and is arranged on this light source board 2, institute
Stating LED light source 21 near the curved arrangement in the edge of this light source board 2, described lens 1 are string configuration corresponding described LED light
The orientation in source 21 is extended.Further, the quantity of described lens 1 is two, respectively the left surface of corresponding described light source board 2
Arrange with the LED light source 21 on right flank.
In the present embodiment, described lens 1 by the described LED light source of one-body molded covering 21 and described LED light source 21 near
Light source board 2.
Described lens 1 are made from a material that be thermally conductive, with described LED light source 21 and light source board 2 thermally coupled while of described lens 1.
The heat that LED light source 21 produces can outwardly distribute through lens 1 in time.It is therefore not necessary to use radiator to carry out auxiliary
Help heat radiation.Lack the restriction of radiator so that the design of all-round light is more prone to realize.
Described lens 1 also include one with the integrated connecting portion of lens 1 13, during assembling, described connecting portion 13 is fixed on
Described lamp holder 1 and the connection end of light source board 2.
In the present embodiment, the most described reflecting surface 11 includes reflecting segment 111 and refraction section 112, described refraction section
112 is the middle part cambered surface of described reflecting surface 11.
Described reflecting segment 111 is for the some light sent towards plane of refraction 12 reflex LED light source 21 of these lens 1, institute
State refraction section 112 for outwards being reflected by the some light that LED light source 21 sends.Therefore, to form one semi-transparent semi-reflecting for reflecting surface 11
Penetrating face, the some light that LED light source 21 sends penetrates after being directly over reflecting section 112 refraction, the part light that LED light source 21 sends
Line reflects injection after reflecting segment 111 reflexes to plane of refraction 12.After being arranged such, the region of reflecting surface 11 correspondence also has light
Line penetrates, and by adjusting the radian of reflecting surface 11, there is beam projecting in the region that reflecting surface 11 can be allowed to be distributed, has reached true
The light-out effect of positive all-round light.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is as the criterion with scope of the claims.
