[detailed description of the invention]
Please refer to shown in Fig. 1 and Fig. 3, a kind of LED 1 of the present invention, comprises 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, have an installation direction when lens 3 are installed on radiator 2, have a mounting plane 5 when LED light source 4 is installed on radiator 2, and mounting plane 5 is a plane of radiator 2, and for installing LED light source 4, installation direction is perpendicular to mounting plane 5.The structure of lens 3 polyhedron shape, and be installed on radiator 2 along the direction vertical with the mounting plane 5 of LED light source 4, make lens 3 can be good at guiding the angle of light, the exit direction of adjustment light.
Namely LED 1 is penetrated after the rays pass through lens 3 of LED light source 4.LED 1 of the present invention does not need other lampshade or lamp housing, and using the cover body of lens 3 as LED 1, LED light source 4 is positioned at lens 3.Thus make the structure of LED 1 of the present invention simple, easy for installation, angular can be adjusted easily again.
In the present embodiment, the size of lens 3 is comparatively large, and the width of lens 3 the widest part is greater than the width of radiator 2 the widest part.With the widest part of lens 3 for line of demarcation, lens 3 are divided into top 301 and bottom 302.Top 301 is contrary with bottom 302 configuration.The width on top 301 increases from top to bottom gradually, and the width of bottom 302 reduces from top to bottom gradually.The outer surface of top 301 and bottom 302 is corresponding in the mounting direction.In the present embodiment, the outer surface of the side on top 301 has 6 inclined-planes, and the outer surface of the side of bottom 302 also has 6 inclined-planes, and 6 of top 301 inclined-planes are corresponding with 6 incline positions of bottom 302.Lens 3 extend along the direction deviating from radiator 2 from radiator 2, and width becomes gradually and diminishes gradually more greatly, and ends at the first surface 31 that is parallel to mounting plane 5.Not only the width of the widest part of each latitude of side of the outer surface of lens 3 broadens gradually from LED light source 4 one end but also narrows gradually.First surface 31 is an outer surface of lens 3, and first surface 31 is parallel to mounting plane 5, makes the anatomic shape of whole LED 1 lamp body generous and is easy to manufacture.First surface 31 connects the side of the outer surface of described lens 3.The entirety that lens 3 are formed in one.
Lens 3 are the polyhedron shape of hollow, have an optics cavity 32, and LED light source 4 is in optics cavity 32 or in radiator 2 or between radiator 2 and optics cavity 32, and 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 roughly the cone reduced gradually from LED light source 4 one end width.Optics cavity 32 can not be a regular cone, and its tip may not be and comes together in a bit but a less plane.The axis 33 of optics cavity 32 is roughly vertical with mounting plane 5, and extends along installation direction.The tip of cone is near first surface 31, and after making the refraction of the rays pass through lens 3 of LED light source 4, light mainly penetrates to the side of lens 3, and the first surface 31 to lens 3 of minute quantity penetrates.Such LED 1 effectively can reduce dazzle.And this kind of LED 1 is applicable to being applied to Crystal lamp light fixture very much, as the light source of Crystal lamp light fixture.The light of LED 1, mainly to side injection, is just in time located on the crystal suspension member of Crystal lamp, makes whole lamp more dazzling like this.
As shown in Figure 3, further, in the present embodiment, lens 3 are axially symmetric structure, its cross section perpendicular to mounting plane 5 is roughly the hexagon of openings at one side, and can regard as and be made up of two be connected to each other trapezoidal of going to the bottom, thus superposed outer surface in the outer surface of lens 3 is made towards oblique upper, to be positioned at the outer surface of bottom obliquely downward.The cross section perpendicular to mounting plane 5 of optics cavity 32 is roughly triangle.The light of LED light source 4 mainly penetrates obliquely upward after lens 3.Fig. 4 is the distribution curve flux of LED 1 of the present invention, can find out that LED 1 scioptics 3 of the present invention make directly to upper light relatively less, and the light penetrated obliquely upward is relatively many.In other embodiments, the shape of lens 3 also can be changed as required.
As shown in Figure 3, because the cover body of lens 3 as LED uses, in order to the profile of fit lens 3, in the present embodiment, radiator 2 is also polyhedron shape.The polyhedron of radiator 2 is corresponding near the polyhedron of the part of radiator 2 with lens 3, and namely the polyhedron of radiator 2 is corresponding with the polyhedron of lens 3 bottom.Polyhedral outer surface of radiator 2 has some inclined-planes, and in the present embodiment, this some inclined-plane is all quadrangle, and is all trapezoidal, and each inclined-plane is connected with adjacent inclined-plane.The polyhedron of radiator 2 is corresponding with the polyhedron of the bottom 302 of lens 3, and namely on latitude direction, the number on the inclined-plane of both outer surfaces is identical, and position is corresponding.
Radiator 2 is have a breach trapezoidal perpendicular to the cross section of mounting plane 5.Indentation, there is the receiving space 21 of radiator 2.LED light source 4 is positioned at receiving space 21, and lens 3 are fixed in the receiving space 21 of radiator 2, and the lateral wall of lens 3 abuts with the madial wall of radiator 2.In other embodiments, the shape of radiator 2 also can change as required, such as, be revised as traditional cylindrical etc.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
