Description
Technical field
The utility model relates to a kind of illuminating lens, especially relates to a kind of explosion type luminous lens.
Background technology
For the demand of illumination, the mankind's one of demands the most widely, from time immemorial flint wood get fire ancient times read by the light of bagged fireflies or the reflected light of snow, stamp wall clean out, none is not reflection human progress and positive history of striking out of oneself, and simultaneously vividly reflects that " light " this bright and full of hope vocabulary is to human history progress far-reaching influence yet; Illumination allows people be broken away from dark fear, and since the appearance having artificial light sources, artificial light sources just illuminates the step that the mankind are makeed one's way.Even can say, throw light on along with the progress each time of the mankind.As novel high efficiency illumination light source, the appearance of LED has epoch-making meaning, and compared to conventional light source, LED has high efficiency, low energy consumption, high brightness, environmental protection, a series of remarkable advantage such as extra long life.In daily life, there is in development in science and technology purposes widely.
LED usually uses lens as lampshade in the application, i.e. lens and lampshade integrated design, such lens possess optically focused and protective action simultaneously, avoid the waste of light.
Existing LED lens are used for illumination and furnishing fields, and possess profile miscellaneous and light-out effect according to the difference of use occasion, but illuminating lens of the prior art, the beam angle of LED light source after its outgoing is limited, can not effectively form polarizers of big angle scope bright dipping, and even luminosity cannot be ensured while increase rising angle, luminous energy cannot be utilized as much as possible to greatest extent, cause optical energy loss rate high.
And need a kind of good looking appearance generous some occasion people, explosion type bright dipping can be formed in lensed endface, the luminous lens of good even photosensitiveness can be ensured.And also without any a lens, there is such effect in prior art.
Utility model content
In order to realize above-mentioned effect, the utility model provides a kind of novel wide-angle luminous lens, and good looking appearance is generous, can form the light-out effect of wide-angle, can also ensure that emergent ray is in corresponding being spatially evenly distributed of exiting surface simultaneously in the side of lens.
