Description
Technical field
The present invention relates to luminous lighting field, particularly to luminous lighting equipment technical field, specifically refer to a kind of luminous
Lamp body concentrator lens structure and corresponding illuminator.
Background technology
Along with the most progressive and scientific and technical development of human civilization, illuminator is early well known.Always
In fact, this kind of illuminator includes housing and the luminous component being arranged in described housing.
Along with the progress of technology, LED have been able to provide enough luminous energy for lighting use, in order to reduce the energy of illumination
Source consumes, and reduces the discharge of carbon dioxide, for promoting the continuous advance in alternative source of light market, with LED light source replace electric filament lamp and
Halogen light has been trend of the times, and consumer what is desired is that the light quantity that can reach electric filament lamp or Halogen light exports, has simultaneously
There are lower energy consumption and longer service life, better quality products at good values.Although there being many different LED product on market
Releasing, but wherein great majority are too expensive for ordinary consumer, and properties of product are not producing a desired effect.
According to optical principle, light is easy to be reflected by biconvex lens and reach spotlight effect, and same in order to obtain
Spotlight effect and reduce the thickness of lens as far as possible, can use Fresnel Lenses replace routine biconvex lens.
Fresnel Lenses (Fresnel lens), also known as Fresnel lens, is by French physician Augustine letter
A kind of lens that Fresnel is invented, the design of these lens was applied to beacon originally, and this design can build more large aperture
Lens, be characterized in that focal length is short, and more less than the material usage of general lens, weight is less with volume.With in early days saturating
Mirror is compared, and Fresnel Lenses is thinner, therefore can reflect more light to form the higher collimated light beam of brightness so that beacon
Even if distance quite far still can be seen that.
The illumination part of conventional Fresnel Lenses spotlight is made up of lamp, Fresnel Lenses and spherical auxiliary mirror.
In general, the filament of lamp all can be fixed on the central point of spherical mirror.Therefore, the some light that lamp sends puts back and is emitted back towards
Coming, before helping, the light of hemisphere is launched.But the light that direction is forward is focused on by Fresnel Lenses. the degree of light focusing is by phenanthrene
Distance between Nie Er lens and lamp determines.If the filament of lamp is positioned in the focus of Fresnel Lenses, then the thinnest by producing
Focal spot.This makes its light path be similar to parallel lines, the most poly-speckle (spot).
Reduce the distance between Fresnel Lenses and lamp, the aperture angle of the luminous point emitted will be made to increase continuously.
This generates the light path dissipated, also referred to as floodlight (flood).
But this light such as has the defect that light tailoring is not enough, and especially in poly-speckle position (spot position), this is main
Owing in this case, space angle scope the most comparatively small in poly-speckle position is covered caused by Fresnel Lenses.
Meanwhile, conventional Fresnel Lenses itself can not play the light to different colours and be scattered the effect of mixing,
Therefore various occasion light source and luminous beam being had to particular requirement cannot be applicable to.
Therefore, the optically focused problem of whole lamp is always technical bottleneck, and meanwhile, how manufacturing one can be by face of the same race
The anaclasis of color goes out specific beam pattern and economical and practical illuminator, is the common problem of puzzlement people all the time.Though
So the technology of LED own has improved, and can send the light of various different colours, but how utilize a kind of simple lens arrangement energy
Enough light fully scattered mixing, reduce manufacturing cost and product complexity, energy-conserving and environment-protective, always put in face of people urgently
Problem to be solved.
