Abstract

The utility model belongs to the technical field of a light emitting diode (LED) lamp optical mask and particularly relates to a scale and shell polyhedral LED lamp optical mask. The scale and shell polyhedral LED lamp optical mask is composed of a plurality of optical mask units (1) compactly arranged. The bottom face of each optical mask unit (1) is of a polygon and the upper surface of each optical mask unit (1) is of a scale and shell shape. The scale-and-shell-shaped upper surface is composed of one or more rows of scale and shell polyhedrons. Different angles are formed by the scale and shell polyhedrons and the bottom faces of the optical mask units (1) so that the scale-and-shell-shaped upper surface of the optical mask is of an arc shape. According to differences of luminous flux distribution requirements needed by practical purposes, the LED lamp optical mask is made of transparent optical glass, polycarbonate or other optical materials and the orientation angle of each surface of the optical mask is different due to different physical characteristics of materials. According to the scale and shell polyhedral LED lamp optical mask, LED lamp luminous flux can be well distributed so that reasonable distribution of the LED lamp luminous flux can be achieved and illuminating quality of an LED lamp is obviously improved.

Description

A kind of scale and shell polyhedron LED light fixture optics face shield and use its LED light fixture

Technical field

The utility model belongs to the optical surface cover structure field that relates to the LED light fixture, relates in particular to a kind of scale and shell polyhedron LED light fixture optics face shield and uses its LED light fixture.

Background technology

Along with the arriving in the 4th illumination-semiconductor lighting epoch in generation, light efficiency, the power of light emitting diode (Light Emitting Diode is called for short LED) improve constantly.Characteristics such as LED is low with its operating voltage, luminous efficiency is high, stable performance, life-span length, shock resistance, vibration resistance is strong, in light weight, monochromaticjty is good, colour rendering is good, application is more and more wider.LED has been widely used in fields such as liquid crystal backlight, normal lighting, traffic lights, automotive lighting and street lighting.Because LED itself is the spot light of small size, can not directly use as illuminations.For satisfying in the practical application performance demands such as light spot shape for light fixture, light distribution, the uniformity, compile after need the LED encapsulation and be used in combination with optics face shield through optical design.Existing optical design and the improvement thereof that LED light fixture optics face shield is carried out of existing lamp illuminating system, prior art mainly utilizes reflector or lens to realize that the light fixture hot spot distributes and inhomogeneity control, but still has the luminous flux utilization rate and in the relatively poor problem of the reasonable distribution of certain space.Therefore, need provide a kind of new LED light fixture optics face shield.

The utility model content

The purpose of this utility model is to overcome light distribution and the inhomogeneity problem that exists in the prior art, provide a kind of and can obtain good led light source luminous flux in the reasonable distribution in space, improve the scale and shell polyhedron LED light fixture optics face shield of luminous flux utilization rate simultaneously, improve the quality of LED light fixture.

The technical solution adopted in the utility model is: a kind of scale and shell polyhedron LED light fixture optics face shield is formed by tight arrangement the in a plurality of optics face shields unit;

The bottom shape of an optics face shield unit is triangle, quadrangle, pentagon, hexagon, decagon, dodecagon or its combination, and its upper surface is the scale and shell shape;

Optics face shield unit scale and shell shape upper surface is made up of a row or multi-row scale and shell polyhedron, and every row's scale and shell polyhedron comprises the scale and shell polyhedron that the identical or a plurality of shapes of one or more shapes match;

The scale and shell polyhedron is square, cuboid, prism, pyramid, terrace with edge or other polyhedrals, its bottom shape is triangle, quadrangle, pentagon, hexagon, decagon, dodecagon or other polygons, adjacent scale and shell polyhedron becomes the angle of gradual change with bottom surface, optics face shield unit, make optics face shield scale and shell shape upper surface curved.

Distribute requirement different according to the required luminous flux of optics face shield practical use, the material of LED light fixture optics face shield can be selected clear optical glass, Merlon, polymethyl methyl esters or other optical materials for use, each surperficial orientation angles is different because of material physical properties on the optics face shield, according to practical use the difference of luminous flux is distributed to require to calculate and determines.

A kind of LED light fixture of using above-mentioned optics face shield is made up of bowl-shape lens, LED and scale and shell polyhedron LED light fixture optics face shield, and LED is positioned at bowl-shape lens bottom surface, and with the coaxial assembling of lens, scale and shell polyhedron LED light fixture optics face shield is connected with the lens upper edge.

Lens in the described LED light fixture are total reflection lens.

Technique effect of the present utility model is: scale and shell polyhedron LED light fixture optics face shield is combined the back for the LED light fixture with lens, can distribute the LED luminous flux well, realizes that LED light fixture luminous flux rationally distributes, and significantly promotes LED lamp lighting quality.
