Description
Technical field
The utility model belongs to light fixture face shield technical field, is specifically related to a kind of banded free-form surface LED light fixture optical mask.
Background technology
Light emitting diode (Light Emitting Diode, LED) is the luminous semiconductor diode of a kind of energy, be a kind of be electric energy conversion directly the luminescent device of light and radiant energy.Light emitting diode has many advantages: operating voltage is low, luminous efficiency, stable performance, life-span long, vibration resistance is strong, lightweight, volume is little.In recent years, LED more than white light LEDs has reached 100lm/W, has possessed and has been applied to that automotive lighting, traffic signals show, LED shows and all conditions in normal lighting field when solving all colours and showing problem.LED has been widely used in traffic lights, the fields such as the liquid crystal display back of the body light fixture, automotive lighting and normal lighting at present.But LED is not equal to the LED light fixture, and LED itself is spot light, can not directly apply to various lightings.
At the LED lighting field, a lot of producers only covet the LED street lamp the electricity effect and ignored optical effect, only be concerned about that namely can light source normally light, and do not go to consider whether the optics aspect reaches the optics requirement.Especially inner common especially at the field that the light fixture light intensity is had specific (special) requirements (LED street lamp, LED traffic lights, LED car headlamp, LED navigation light and LED automobile tail light etc.).Country has progressively set up national standard in the field of light fittings of special dimension, such as: in LED garage's signal lamp field, the GB14887-2003 standard is arranged; In the car headlamp field, GB4599-1994 standard etc. is arranged.Most importantly the clear and definite various performance requirements of various light fixtures have proposed requirement to the light spot shape of light fixture, light distribution, the uniformity etc.
The conventional lamp illuminator has been carried out design and the exploration of optical design, mainly utilizes reflector or lens to realize the distribution of light fixture hot spot, light distribution and inhomogeneity control.In the LED light fixture, because LED and conventional light source have very big-difference, the secondary optical design of LED light fixture is one of most important technology in the LED lighting field, how reasonable distribution LED light source luminous flux, and then improve the luminous flux utilization rate, be the problem that the LED lighting field is needed solution badly.
The utility model content
The utility model technical issues that need to address are: a kind of banded free-form surface LED light fixture optical mask is provided, and it can reasonable distribution LED light source luminous flux, and then improves the luminous flux utilization rate, improves LED lamp lighting quality.
The technical solution of the utility model is as described below:
A kind of banded free-form surface LED light fixture optical mask is formed by several optical mask unit spliceds; Described optical mask unit by one or more free form surface polyhedrons from front then, be different angles and be spliced.
As preferred version,
Described free form surface polyhedron upper surface is free form surface, is arch; The lower surface is the bottom surface; The different polyhedral free form surfaces of free form surface and bottom surface are different angles.The polyhedral bottom surface of described free form surface can be triangle or quadrangle or pentagon or hexagon or decagon or dodecagon or its combination.
Described banded free-form surface LED light fixture optical mask can adopt the transparent optical materials such as optical glass, PC, PMMA.
The beneficial effects of the utility model are:
Banded free-form surface LED light fixture optical mask of the present utility model has been realized the distribution of LED light fixture hot spot, light distribution and inhomogeneity effective control, can reasonable distribution LED light source luminous flux, and then improve the luminous flux utilization rate, significantly improve LED lamp lighting quality.

The specific embodiment
Below in conjunction with drawings and Examples, banded free-form surface LED light fixture optical mask of the present utility model is elaborated.
Banded free-form surface LED light fixture optical mask of the present utility model is formed by several optical mask unit spliceds.
As shown in Fig. 1 a～Fig. 1 d, described optical mask unit by one or more free form surface polyhedrons from front then, be different angles and be spliced.
As shown in Fig. 2 a～Fig. 2 c, the polyhedral surface parameter of described free form surface is calculated according to the specific requirement of different lamps and is got, and described Computation of surface parameters method is field of lamp illumination number personnel common practise.Free form surface polyhedron in the present embodiment, its upper surface is free form surface, is arch; The lower surface is the bottom surface; The different polyhedral free form surfaces of free form surface and bottom surface are different angles.
The polyhedral bottom surface of described free form surface can be triangle or quadrangle or pentagon or hexagon or decagon or dodecagon or its combination.
The material of banded free-form surface LED light fixture optical mask is the transparent optical materials such as optical glass, PC, PMMA.
With the light fixture of banded free-form surface LED light fixture optical mask of the present utility model, can in conjunction with total reflection lens (TIR) or lens, can realize that luminous flux distributes control and the reasonable hot spot of luminous flux to distribute.In using other methods that obtain directional light, also can combine with the banded free-form surface LED light fixture optical mask in the utility model, obtain ideal effect.
