Description
Technical field: the present invention relates to optical lens, be specially adapted to LED low-angle light-emitting lens.
Prior art: led light source is efficient with it, energy-saving and environmental protection, long-life, undersized advantage have been widely used in imaging lighting fields such as background light source, display device, duplicator, laser printer, above-mentioned application is confined to closely face battle array illumination usually, the simple grain combination shows purposes, this is because the decision of the LED scattering characteristics of luminescence, its initial angle of divergence can be near 180 °, this is favourable for large area lighting closely, but illumination distances is limited.Therefore, LED producer has carried out simple luminous intensity distribution usually when encapsulation, shrink the angle of divergence.For example adopt the lens pillar encapsulation, can a certain amount of contraction angle of divergence, can see 60 °, 30 °, the 15 ° half-power angles of divergence on the market, but its light utilization efficiency is low, collector lens directly contacts with the luminescence chip encapsulation, and the operating temperature height is very easily aging, crack, the light transmission of lens is descended greatly.The diffuse reflection in packaging body of a large amount of light produces more thermal energy and causes the further ageing failure of package lens.Some high power light sources are arranged with the combination lighting of above-mentioned LED array, but volume is big, the angle of divergence is bigger than normal, is not easy to high-power long distance light.
Consult the led light source Chinese patent, mainly concentrate on LED encapsulation and in illuminator closely, the most close patent has two.Application number 200380105936.0 " lens array plate and manufacture method thereof ", goal of the invention are effectively diffused light to be gathered a light to utilize the surface (as the imaging surface LCD panel of duplicator or laser printer etc., to belong to closely uniform illumination system.Application number 200710118965.0, " a kind of led light source lens that are used for ", the purpose of invention is to make light that led light source sends form the optical illumination scope of rectangle, square or a strip in the far field behind lens, and the strip on road surface evenly throws light on when conveniently being used for the road illumination.Be used for the LED street lighting and belong to the middle distance illuminator.The light beam of its outgoing differs greatly at X and two perpendicular orientation angles of divergence of Y, can't be to long distance light.And owing to will cut out the illumination field of view of rectangle, by or cut part light, caused the loss of light energy.
Safety defense monitoring system such as safe city engineering has tended to day and night round-the-clock monitoring in recent years, and to outdoor monitoring at night, universal demand adopts infrared illumination, to reduce light pollution.LED infrared light supply manufacturing technology and technology are ripe, and near-infrared LED makes it become infrared light supply preferably with low power consuming, long-life characteristics.Under the in-plant illuminator no matter be visible light or infrared light generally adopts LED to make light source.Remote infrared illumination system, what generally adopt at present is single the infrared LED binding array that encapsulates through simple optically focused, forms high-power LED array to long distance light with the large tracts of land binding.But, restricting its further development and application because its volume is big and the previous reasons life-span is short, illuminator maintenance cost height.Have constantly that the safety monitoring user proposes to need that a kind of volume is little, the life-span is long, the length of the high and low energy consumption of luminous efficiency is apart from infrared illumination system, our remote low-angle light-emitting lens group proposes under such Market and Technology background and researches and develops.
Summary of the invention: the objective of the invention is efficiently to collect light energy for after making the secondary light-distribution of large-angle scattered light through reflector and lens that led chip sends, convergent beam realizes that low-angle is to long distance light.A kind of small angle long distance light microscopic group and array are provided.
