【Embodiment】
It refer to shown in Fig. 1 and Fig. 3, a kind of LED 1 of the present invention, including radiator 2, lens 3 and LED light source 4.LED
Light source 4 is fixed on radiator 2, and lens 3 are fixed on radiator 2.Lens 3 are polyhedron shape, and lens 3 have when being installed on radiator 2
There is an installation direction, LED light source 4 has a mounting plane 5 when being installed on radiator 2, mounting plane 5 is one flat for radiator 2
Face, for installing LED light source 4, installation direction is perpendicular to mounting plane 5.The structure of the polyhedron shape of lens 3, and edge and LED light source
The vertical direction of 4 mounting plane 5 is installed on radiator 2 so that lens 3 can be good at guiding the angle of light, adjust light
The exit direction of line.
LED 1 is projected after the rays pass through lens 3 of LED light source 4.LED 1 of the present invention do not need other lampshades or
Person's lamp housing, and the cover body using lens 3 as LED 1, LED light source 4 are located in lens 3.So that the knot of LED 1 of the present invention
Structure is simple, easy for installation, and and can easily adjusts rising angle.
In the present embodiment, the size of lens 3 is larger, and the width of the widest part of lens 3 is more than the width of the widest part of radiator 2.
Using the widest part of lens 3 as line of demarcation, lens 3 divide for top 301 and bottom 302.Top 301 is opposite with the configuration of bottom 302.On
The width in portion 301 gradually increases from top to bottom, and the width of bottom 302 is gradually reduced from top to bottom.Top 301 and bottom 302
Outer surface it is corresponding in the mounting direction.In the present embodiment, the outer surface of the side on top 301 has 6 inclined-planes, bottom
The outer surface of 302 side also has 6 inclined-planes, and 6 inclined-planes on top 301 are corresponding with 6 incline positions of bottom 302.
Lens 3 extend from radiator 2 along away from the direction of radiator 2, and width becomes larger to be tapered into again, and it is parallel to terminate at one
In the first surface 31 of mounting plane 5.That is the width of the widest part of each latitude in side of the outer surface of lens 3 is from LED light source 4
One end gradually broadens and become narrow gradually.First surface 31 is an outer surface of lens 3, and first surface 31 is parallel to mounting plane
5 so that the anatomic shape of the whole lamp body of LED 1 is generous and easily fabricated.First surface 31 connects the outer surface of the lens 3
Side.The entirety that lens 3 are formed in one.
Lens 3 are hollow polyhedron shape, have an optics cavity 32, and LED light source 4 is located in optics cavity 32 or radiator 2
Interior or between radiator 2 and optics cavity 32, optics cavity 32 is polyhedron shape.
The polyhedron of optics cavity 32 is corresponding with the polyhedron of lens 3, and optics cavity 32 is substantially wide from the one end of LED light source 4
Spend the cone being gradually reduced.Optics cavity 32 can not be a regular cone, its tip may not be come together in a little and
It is a less plane.The axis 33 of optics cavity 32 is substantially vertical with mounting plane 5, and extends in assembly direction.Cone
Tip close to first surface 31 so that light is mainly to the side of lens 3 after the refraction of the rays pass through lens 3 of LED light source 4
Project, and minimal amount of projected to the first surface 31 of lens 3.Such LED 1 can effectively reduce dazzle.And this kind
LED 1 is highly suitable to be applied for Crystal lamp light fixture, the light source as Crystal lamp light fixture.The light of LED 1 is mainly penetrated to side
Go out, be just located on the crystal suspension member of Crystal lamp, so that whole lamp is more dazzling.
As shown in figure 3, further, in the present embodiment, lens 3 are axially symmetric structure, its horizontal stroke perpendicular to mounting plane 5
The hexagon of section substantially openings at one side, and can regard as by trapezoidal the forming of two bottom interconnections, so that thoroughly
Superposed outer surface is towards oblique upper in the outer surface of mirror 3, positioned at the outer surface of bottom obliquely downward.Optics cavity 32
It is have a generally triangular shape perpendicular to the cross section of mounting plane 5.The light of LED light source 4 is mainly penetrated obliquely upward after lens 3
Go out.Fig. 4 is the distribution curve flux of LED 1 of the present invention, it can be seen that light of the LED 1 of the present invention by lens 3 directly up
Line is relatively fewer, and the light projected obliquely upward is relatively more.In other embodiment, the shape of lens 3 can also be according to need
Change.
As shown in figure 3, because cover body of the lens 3 as LED uses, for the profile of fit lens 3, in the present embodiment
Radiator 2 is also polyhedron shape.The polyhedron of radiator 2 is corresponding with polyhedron of the lens 3 close to the part of radiator 2, that is, dissipates
The polyhedron of hot device 2 is corresponding with the polyhedron of the bottom of lens 3.Polyhedral outer surface of radiator 2 has some inclined-planes, this reality
It is all quadrangle to apply some inclined-planes of this in example, and is all trapezoidal, and each inclined-plane connects with adjacent inclined-plane.The multiaspect of radiator 2
Body is corresponding with the polyhedron of the bottom 302 of lens 3, i.e., on latitude direction, the number on the inclined-plane of both outer surfaces is identical,
And position correspondence.
Radiator 2 is with the trapezoidal of a breach perpendicular to the cross section of mounting plane 5.Indentation, there is the receipts of radiator 2
Hold space 21.LED light source 4 is located in receiving space 21, and lens 3 are fixed in the receiving space 21 of radiator 2, and lens 3
Lateral wall abuts with the madial wall of radiator 2.In other embodiment, the shape of radiator 2 can also change as needed, such as
It is revised as traditional cylindrical etc..
It should be noted that embodiments of the invention have preferable implementation, and not the present invention is made any type of
Limitation, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above equivalent effective
Embodiment, as long as without departing from the content of technical solution of the present invention, above example is made according to technical spirit of the invention
Any modification or equivalent variations and modification, in the range of still falling within technical solution of the present invention.
