Description

本発明は、表示装置等に用いられるLED(発光ダイオード)チップ等の発光素子の上部を被覆して配設し発光素子の光を収束する集光レンズに係り、特に小径な発光素子からの光を広い発光面積でかつ効率良く好適に照射することができる発光素子用レンズに関するものである。 The present invention relates to a condenser lens for converging the light of LED (light emitting diode) and disposed to cover the top of the light emitting device chip such as a light emitting element used in display apparatus or the like, the light from the particular small light-emitting element it relates a wide light-emitting area and efficient well suitably for a light-emitting element lens can be irradiated.

元来、LED等の発光素子そのものの発光する領域はピンポイントであり、そのままでは無指向性の照明となり光が拡散してしまい、一定程度の面積の発光面を形成できず、また遠距離からの視認性も劣ることから、通常発光素子前方を覆って光を収束させる集光レンズを配設することが行われている。 Originally, the light emitting region of the light emitting element itself, such as an LED is pinpoint, as is the cause by light becomes a lighting omnidirectional diffuse, it can not form a light-emitting surface of a certain degree of area, also from a distance from inferior possible visibility, has it been conducted to arrange the normal light emitting element condenser lens which covers the front to focus the light. この集光レンズは、底部に発光素子取付部を形成し、この底部から前方に向かって放物線曲線を描く壁面で、発光素子からの光を全反射して前方へと放射するものである。 The condenser lens forms a light emitting element mounting portion on the bottom, the wall of a parabola curve forward from the bottom part which emits forward by totally reflecting the light from the light emitting element.

しかしながら、上述した従来の発光素子用レンズにあっては、確かに発光素子の光を収束させることで光の散乱を抑えて光を前方に真っ直ぐ照射し、これにより遠距離からの視認性には優れるものの、逆に光の散乱が抑えられることで視認可能範囲である視野角が狭くなるという問題が生じていた。 However, in the conventional light-emitting element lens described above, straight irradiating light forward suppress certainly scattering of light by converging the light from the light emitting element, thereby visibility from a distance is excellent though, a problem that the viewing angle is visible range by scattering of light in the opposite is suppressed narrowed had occurred. 特に表示装置として用いる場合には、遠距離からの視認性とともに広視野角であることも重要なポイントとなっている。 In particular, when used as a display device is also an important point that a wide viewing angle with visibility from a distance.

そこで本発明にあっては、上述した課題を解決すべく、近距離は勿論のこと遠距離からの視認性に優れるとともに視野角特性にも優れた発光素子用レンズの提供を目的とする。 According to the invention, therefore, to solve the problem described above, a short distance and an object thereof is to provide a light-emitting element lens excellent in viewing angle characteristics is excellent in visibility from a distance of course.

上記目的を達成するため、本発明の発光素子用レンズは、レンズ体の底部に形成した発光素子取付部に配設される発光素子からの発光をレンズ体の周壁で全反射して前方へ放射する逆円錐台状の発光素子用レンズの上記周壁には、該レンズ体の中心軸との角度を上記底部からレンズ前面にかけて変化させることで形成される角部を1個所若しくは複数個所周設することにより、上記発光素子からの光をこの周設された角部が前面に散乱してレンズ前方から見て同心円状に照射することを特徴とする。 To achieve the above object, the light-emitting element lens of the present invention, total reflection to emit forward light emitted from the light-emitting element disposed on the light emitting element mounting portion formed on the bottom of the lens body at the peripheral wall of the lens body to the above peripheral wall of inverted truncated cone shape of the light-emitting element lens and angle settings circumferential one position or plural positions a corner portion formed by changing over the lens from the bottom of the central axis of the lens body it makes wherein the corner portion which is the circumferentially provided the light from the light emitting element is irradiated concentrically when viewed from the lens forward scattered to the front.

レンズ前面の中央部には凸レンズ部を突設形成したことを特徴とする。 The central portion of the lens front surface is characterized in that projecting form a convex lens portion.

また、レンズ前面の中央部には凸レンズ部を突設形成するとともに、該凸レンズ部の外周には断面が半球状の凸条を周回状に突設形成したことを特徴とする。 Also, the central portion of the front lens surface while projecting form the convex lens portion, the outer periphery of the convex lens portion, characterized in that the cross section is projected forming a hemispherical projections to circularly.

本発明の発光素子用レンズによれば、レンズ体の底部に形成した発光素子取付部に配設される発光素子からの発光をレンズ体の周壁で全反射して前方へ放射する逆円錐台状の発光素子用レンズの上記周壁には、該レンズ体の中心軸との角度を上記底部からレンズ前面にかけて変化させることで形成される角部を1個所若しくは複数個所周設することで、この周設された角部が上記発光素子からの光を前面に散乱してレンズ前方から見て同心円状に照射することとなり、これによりレンズの前面には周壁で全反射した平面光と、この平面光よりも明るい同心円状のリング光とが一緒になった光の照射が得られ、近距離は勿論のこと、このリング光により遠距離でも優れた視認性が得られるものである。 According to the light emitting element lens of the present invention, inverted truncated cone shape for radiating forward totally reflects light emitted from the light emitting element disposed on the light emitting element mounting portion formed on the bottom of the lens body at the peripheral wall of the lens body of the above peripheral wall of the light emitting element lens, by an angle a set peripheral one position or plural positions a corner portion formed by changing over the lens from the bottom of the central axis of the lens body, the peripheral corner that is set becomes possible to irradiate concentrically when viewed from the lens forward light scattered in front from the light emitting element, and thereby the front surface of the lens is totally reflected by the wall plane light, the plane light and bright concentric ring optical than irradiation of light together is obtained, short distance, of course, are those excellent visibility even in a long distance by the ring light.

また、レンズ前面の中央部には凸レンズ部を突設形成することで、レンズ体周壁では反射せずに直接レンズ中央部分を透過する光が凸レンズ部で収束し、より一層拡散を抑えて遠方にまで光を照射することができる。 Further, the center portion of the front lens surface by projecting form the convex portion, the lens body wall is light passing through the lenses directly central portion without being reflected and converged by the convex lens portion, the distal suppressing the further diffusion light can be irradiated to. さらに、レンズ前面と凸レンズ部との境界には、発光素子からの光が他の部分よりも多く集まって明るいリング光となって前面に照射されることとなり、近距離は勿論のこと、遠距離での視認性も向上させる。 Furthermore, the boundary between the lens front surface and the convex lens portion may become the light from the light emitting element is irradiated to the front surface becomes bright ring light gathered more than other portions, a short distance, of course, far visibility in also be improved.

また、レンズ前面の中央部には凸レンズ部を突設形成するとともに、該凸レンズ部の外周には断面が半球状の凸条を周回状に突設形成することで、レンズ体周壁では反射せず、かつ凸レンズ部も透過することなく、凸レンズ部の外周を透過する光が上記凸条で収束し、さらに一層拡散を抑えて遠方に光を照射することができる。 Further, with the center of the lens front surface to protrude form the convex lens portion, the outer periphery of the convex lens portion that cross section to protrude form the hemispherical projections to circumferentially, not reflected in the lens body wall and without the convex lens portion is also transmitted, it is possible to light transmitted through the outer periphery of the convex lens portion is converged by the ridge, further irradiated with light in the distance by suppressing the more diffuse. そして、レンズ前面と凸条との境界が、同心円状に2重に形成され、発光素子からの光が他の部分よりも多く集まって明るいリング光となって前面に照射されることとなり、発光素子からの光が他の部分よりも多く集まって明るいリング光となって前面に照射されることとなり、近距離は勿論のこと、遠距離での視認性もさらに一層向上させる。 The boundary between the lens front surface and the projections are formed doubly concentrically, it becomes possible to light from the light emitting element is irradiated to the front surface becomes bright ring light gathered more than the other portions, the light emitting becomes the light from the device is irradiated to the front it becomes bright ring light gathered more than other portions, a short distance, of course, further to further improved visibility in long distance.
