Abstract
The invention belongs to the technical field of lamp masks, and particularly relates to a conical LED lamp optical mask which comprises one or multiple optical mask units. Each optical mask unit comprises a cone and a plurality of circular truncated cones, each cone is stacked at the top, the circular truncated cones are erected and stacked below the corresponding cone according to undersurface radius from small to big, the undersurface of each cone is identical with the upper undersurface of the circular truncated cone adjacent to the cone in radius, and the lower undersurface of each circular truncated cone is identical with the upper undersurface of the circular truncated cone below in radius. By the conical LED lamp optical mask, luminous flux of an LED light source can be reasonably distributed, so that luminous flux utilization rate is increased, and lighting quality of an LED lamp is improved.
Description
Technical field
The invention belongs to light fixture face shield technical field, be specifically related to a kind of cone LED light fixture optical mask.
Background technology
Along with light efficiency, the power of light emitting diode (Light Emitting Diode, LED) improve constantly, the 4th illumination-semiconductor lighting epoch in generation arrived.LED has lot of advantages: as low in operating voltage, luminous efficiency is high, stable performance, the life-span is long, monochromaticjty good, colour rendering is good etc.LED has been widely used in the fields such as liquid crystal backlight, normal lighting, traffic lights, automotive lighting and street lighting.But LED is not equal to LED light fixture, LED itself is spot light, and light is dazzled in the too high easy generation of high-power LED lighteness, thereby LED can not directly apply in lighting.
At LED lighting field, a lot of producers only covet LED street lamp electricity effect and ignored optical effect, be only concerned about that can light source normally light and not go to consider whether optics aspect reaches optics requirement.Along with China and drug in some provinces have proposed the standard file of LED light fixture, relevant criterion is more and clearer and more definite.Only has the quality that could improve LED light fixture by secondary optical design.The secondary optical design of LED light fixture is one of most important technology in LED lighting field.
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.Because LED and conventional light source have very big-difference, how reasonable distribution LED light source luminous flux, and then improve luminous flux utilization rate, be the problem that LED lighting field is needed solution badly.
Summary of the invention
The technical issues that need to address of the present invention are: propose a kind of cone LED light fixture optical mask, it can reasonable distribution LED light source luminous flux, and then improves luminous flux utilization rate, improves LED lamp lighting quality.
Technical scheme of the present invention is as described below:
A kind of cone LED light fixture optical mask, comprises one or more optical masks unit; Described optical mask unit comprises a circular cone and several round platforms, and circular cone overlays the top, and round platform is according to the upright from childhood and greatly circular cone below that overlays of bottom surface radius; Circular cone bottom surface is identical with the round platform upper bottom surface radius adjacent with it, and the bottom surface of each round platform is identical with the round platform upper bottom surface radius that is positioned at its below.
As preferred version,
For described circular cone and several round platforms, the angle that bus and bottom surface form is different, and the angle that bus and bottom surface form is preferably from top to bottom and increases successively.
Face shield material can be transparent optical material, as optical glass or PC or PMMA.
Described optical mask unit is one or more.Described optical mask unit can be arranged on polygon bottom surface, so that multiple optical masks unit can along plane or surface joining together, form optical mask cell array.Described polygon bottom surface can be triangle or quadrangle or pentagon or hexagon or decagon or dodecagon or its combination.
Cone LED light fixture optical mask of the present invention can be spliced into optical mask cell array along plane or curved surface arrangement by one or more optical masks unit; Each optical mask unit is formed by stacking from top to bottom by a circular cone, two round platforms.
Beneficial effect of the present invention is:
Cone LED light fixture optical mask of the present invention 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 luminous flux utilization rate, significantly improve LED lamp lighting quality.

The specific embodiment
Below in conjunction with drawings and Examples, cone LED light fixture optical mask of the present invention is elaborated.
As shown in Fig. 1 a ~ Fig. 1 c, cone LED light fixture optical mask of the present invention comprises one or more optical masks unit.
As shown in Fig. 2 a ~ Fig. 2 c, described optical mask unit comprises: a circular cone and several round platforms, and circular cone overlays the top, and round platform is according to the upright from childhood and greatly circular cone below that overlays of bottom surface radius; Circular cone bottom surface is identical with the round platform upper bottom surface radius adjacent with it, and the bottom surface of each round platform is identical with the round platform upper bottom surface radius that is positioned at its below; For described circular cone and several round platforms, the angle that bus and bottom surface form is different.
The material of cone LED light fixture optical mask is transparent optical material, the angle that described circular cone and round platform bus and bottom surface form because of face shield material different and different.The concrete of described angle determines that method is field of lamp illumination technical staff common practise.
Described optical mask cellular installation is on polygon bottom surface, this bottom surface can be triangle or quadrangle or pentagon or hexagon or decagon or dodecagon or its combination, can be easily by multiple optical masks unit along plane or surface joining together, form optical mask cell array.
Cone LED light fixture optical mask in the present embodiment, forms optical mask cell array by seven optical mask unit along plane or curved surface arrangement; Each optical mask unit is formed by stacking from top to bottom by a circular cone, two round platforms, and the angle that its bus and bottom surface form increases successively.The transparent optical materials such as material selection optical glass, PC or the PMMA of cone LED light fixture optical mask.
With the light fixture of cone LED light fixture optical mask of the present invention, can, in conjunction with total reflection lens (TIR) or lens, be applied to the LED such as lambert's body LED, can realize luminous flux and distribute control and the reasonable hot spot of luminous flux to distribute.In application, other obtain in the method for directional light, also can combine with the cone LED light fixture optical mask in the present invention, obtain ideal effect.
