Description
Technical field
The invention belongs to the optical mask construction applications of LED lamp, particularly relate to a kind of scute Polyhedral LED lamp
Optical mask.
Background technology
Along with forth generation illumination the semiconductor lighting epoch arriving, light emitting diode (Light EmittingDiode,
Be called for short LED) light efficiency, power improves constantly.LED is low with its running voltage, luminous efficiency is high, stable performance, life-span length, anti-impact
The feature such as hitting, vibration resistance is strong, lightweight, monochromaticity good, color rendering properties is good, application is more and more wider.LED the most extensively applies
In fields such as liquid crystal backlight, normal lighting, traffic light, automotive lighting and street lightings.Owing to LED itself is small size
Point source, it is impossible to directly as illuminations use.In applying for satisfied reality, light spot shape, light intensity for light fixture are divided
The requirement of the performance such as cloth, the uniformity, collects after needing to encapsulate LED and is used in combination with the optical mask through optical design.
Optical design that LED lamp optical mask has been carried out by existing lamp illuminating system and improvement thereof, prior art is the most sharp
Realize the control of the distribution of light fixture hot spot and uniformity with reflector or lens, but still suffer from luminous flux utilization rate and certain empty
Between the poor problem of reasonable layout.Accordingly, it is desirable to provide a kind of novel LED lamp optical mask.
Summary of the invention
It is an object of the invention to overcome light distribution and the problem of uniformity present in prior art, it is provided that one can obtain
Obtain the good LED light source luminous flux reasonable layout in space, improve the scute Polyhedral LED lamp of luminous flux utilization rate simultaneously
Optical mask, improves the quality of LED lamp.
The technical solution used in the present invention is: a kind of scute Polyhedral LED lamp optical mask, by multiple optical mask lists
Unit's close-packed arrays forms；
The bottom shape of one optical mask unit is triangle, tetragon, pentagon, hexagon, decagon, twelve edge
Shape or a combination thereof, its upper surface is scute shape；
Optical mask unit scute shape upper surface is made up of a row or multi-row scute polyhedron, and often row's scute polyhedron comprises
The scute polyhedron that one or more shapes are identical or multiple matching form closes；
Scute polyhedron is square, cuboid, prism, pyramid, terrace with edge or other polyhedrals, and its bottom shape is three
Dihedral, tetragon, pentagon, hexagon, decagon, dodecagon or other polygons, adjacent scute polyhedron and optics
Face shield unit bottom surface becomes the angle of gradual change, makes optical mask scute shape upper surface curved.
Requiring difference according to luminous flux distribution needed for optical mask practical use, the material of LED lamp optical mask is optional
By clear optical glass, Merlon, polymetylmetacrylate or other optical materials, the angle of orientation on each surface on optical mask
Spend because material physical properties is different different, according to practical use, the different distribution of luminous flux are required that calculating determines.
A kind of LED lamp applying above-mentioned optical mask, by bowl-shape lens, LED and scute Polyhedral LED lamp optical surface
Cover composition, LED is positioned at bowl-shape lens base, coaxially assembles with lens, on scute Polyhedral LED lamp optical mask and lens
Along connecting.
Lens in described LED lamp are total reflection lens.
The solution have the advantages that: scute Polyhedral LED lamp optical mask is used for LED lamp after being combined with lens,
LED light flux can be distributed well, it is achieved LED lamp luminous flux reasonable layout, be obviously improved LED lamp illumination quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the light fixture applying optical mask of the present invention
Fig. 2 is the side view of light fixture in Fig. 1
Fig. 3 is the optical mask cell schematics of optical mask of the present invention
In figure, 1-optical mask unit, 2-lens, 3-LED.
Detailed description of the invention
The present invention is described further with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, a kind of scute Polyhedral LED lamp optical mask, by multiple optical mask unit 1
Close-packed arrays forms；
One optical mask unit 1, its shape, as it is shown on figure 3, bottom shape is tetragon, curved surfaces has three rows
Scute polyhedron, often row's scute polyhedron comprises five identical scute polyhedrons of shape；
Scute polyhedron is pyramid-shaped, and bottom shape is tetragon, adjacent scute polyhedron and optical mask unit 1 end
Face becomes the angle of gradual change, makes optical mask scute shape upper surface curved.
Requiring difference according to luminous flux distribution needed for optical mask practical use, the material of LED lamp optical mask is optional
By clear optical glass, Merlon, polymetylmetacrylate or other optical materials, the angle of orientation on each surface on optical mask
Spend because material physical properties is different different, according to practical use, the different distribution of luminous flux are required that calculating determines.
A kind of LED lamp applying above-mentioned optical mask, by bowl-shape total reflection lens 2, LED 3 and scute polyhedron LED
Light fixture optical mask forms, and LED3 is positioned at total reflection lens 2 bottom surface, coaxially assembles with lens 2, scute Polyhedral LED lamp
Optical mask 3 is connected with edge on lens 2.
Being explained in detail embodiments of the invention above, above-mentioned embodiment is only most highly preferred embodiment of the invention,
But the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to
Make a variety of changes without departing from the premise of present inventive concept.
