Description
Technical field
This utility model relates to optical lens technical field, is specifically related to a kind of light-distribution lens and adopts the illuminator of this light-distribution lens.
Background technology
In lighting technical field, in order to enable the light that light source sends to be distributed according to the needs of people, it is typically required employing various light conversion light is carried out or reflects or reflect or assemble or disperse, so change the propagation path of light, finally give and meet the illumination region that people are actually needed.
In current light conversion, lens are used widely, reason is in that, each side of lens can be used as the reflecting surface of reflection light or as the plane of refraction reflecting light, the relative position of each side is unified, there is good reliability and concordance, and easy to process, manufacture simple.
Due to LED light source have power consumption less, the suitability is strong, stability is high, response time is short, environmentally safe, the advantage such as multicolor luminous, just progressively replace conventional light source, have been widely used for various illumination occasion.In order to meet the demand of different application occasion, the illuminating effect wanted to be obtained, it is necessary to adopt secondary light-distribution element such as lens etc. that source light is carried out sub-distribution again.
Tradition light distribution scheme is the light transmission of core by being sent by light source and high angle scattered light realizes the sub-distribution again to light through the mode that fully reflecting surface reflects, this scheme is more weak for the light control ability of light source center part, so, current lens, design at lens illuminates in region, the optics bore of the more little required lens of output illumination angle is more big, central light strength requires that more high required optics of lens height is more high, adopt in this way, although the control ability of light to light source center part can be improved, but such cost is the increase in material cost, too increase the difficulty of injection moulding in lens manufacturing process and the risk of contraction, it is difficult to ensure that designed illuminating effect.
