Description

本発明は、反射鏡付き固体発光素子ランプに関する。   The present invention relates to a solid state light emitting device lamp with a reflecting mirror.

現在、使用されている固体発光素子（ＬＥＤ等）照明器具とは、ＬＥＤの輝度の高さをいかした遠距離からの視認性の良さで信号灯や大型ディスプレイ等に使用されている。
特開平０９−２６５８０７号 特開２００３−１２４５２９号 Currently used solid-state light emitting devices (LEDs, etc.) lighting fixtures are used for signal lights, large displays, etc. because of their high visibility from a long distance using the high brightness of LEDs.
JP 09-265807 A JP 2003-124529 A

本発明が解決しようとする課題は、砲弾型ＬＥＤは透明な樹脂でレンズ一体成型されているために指向角により放射光に円形のリングが発生するなど照射面の明るさが均一にならない。また、砲弾型ＬＥＤの発光素子の側方から斜め前方にかけての放射光がレンズ部分を通過しないため屈折せず前方に放出されること無く側方から斜め前方までの放射光は拡散している。また、ＬＥＤを使用した照明器具の大半はＬＥＤの特性や指向角等を理解せず製造された物が多く反射鏡等は、従来の電球と同様の使用方法をとっている為、ＬＥＤ本体の後方に板状に配置しているか、ＬＥＤを後方から包み込むように広角の放物面鏡が配置してあり反射鏡としての機能を果たしていない。そこで、固体発光素子に最適な反射鏡を用いる事により省エネルギーで明るい固体発光素子ランプを提供することである。   The problem to be solved by the present invention is that the brightness of the irradiated surface does not become uniform, for example, a round ring is generated in the radiated light depending on the directivity angle because the bullet-type LED is integrally molded with a transparent resin. Further, since the emitted light from the side of the light emitting element of the bullet-type LED to the diagonally forward does not pass through the lens portion, the radiated light from the side to the diagonally forward is diffused without being refracted and emitted forward. In addition, most of the lighting fixtures using LEDs are manufactured without understanding the characteristics and directivity angle of the LEDs, and the reflectors are used in the same way as conventional light bulbs. A wide-angle parabolic mirror is arranged so as to wrap around the LED from the rear or wrap the LED from the rear, and does not function as a reflecting mirror. Accordingly, an object of the present invention is to provide an energy-saving and bright solid light-emitting element lamp by using an optimum reflecting mirror for the solid light-emitting element.

本発明の反射鏡付き固体発光素子ランプは回転放物面鏡（または円錐状反射鏡）もしくは、二枚の反射鏡（反射材）を約９０度から３０度程度の角度に合わせ、その接点近傍に固体発光素子を接点とは逆方向に設置して固体発光素子からの拡散放射光の全ての放射光を前方必要な照射面積のみ照射させ、反射集光により照射力を向上させる構造を特徴とする。 The solid-state light emitting element lamp with a reflector according to the present invention has a rotating parabolic mirror (or conical reflector) or two reflectors (reflecting materials) at an angle of about 90 to 30 degrees, and in the vicinity of the contact point. The solid light emitting element is installed in the opposite direction to the contact point, and all the radiated light from the solid light emitting element is irradiated only in the necessary irradiation area in the front, and the irradiation power is improved by reflected condensing. To do.

また、前記の回転放物面鏡（または円錐状反射鏡）を砲弾型ＬＥＤ内部のメタルリード・ インナーリード・メタルステム・メタルポスト等と形称される発光素子部分近傍に配置することにより固体発光素子からの拡散放射光の全ての放射光を前方に照射させる構造を特徴とする。 Further, the above-mentioned rotary parabolic mirror (or conical reflecting mirror) is disposed in the vicinity of a light emitting element portion called a metal lead, an inner lead, a metal stem, a metal post, or the like inside a bullet-type LED. It is characterized by a structure in which all the radiated light of the diffuse radiated light from the element is irradiated forward.

本発明の反射鏡付き固体発光素子電球は側方から斜め前方への放射光を反射鏡により 重複反射させて明るさを増させる構造なので照射面積が三分の一になると、三倍のあかるさになり、照射面積が十分の一になると、十倍のあかるさになる。従って、必要な照射面に固体発光素子の放射光を集中させることが可能なので数分の一から数十分の一の消費電力で同じ照度を有する固体発光素子ランプが開発できた。また、砲弾型ＬＥＤ内部に側方拡散防止用の反射鏡を設置することにより、ＬＥＤの素子発光部の側方から斜め前方に拡散していた二割近い光も前方に照射され輝度がアップする。 The solid light-emitting element bulb with a reflector according to the present invention has a structure in which light emitted obliquely forward from the side is reflected and reflected by the reflector to increase the brightness. When the irradiation area becomes one-tenth, it becomes ten times brighter. Accordingly, since the emitted light of the solid state light emitting element can be concentrated on the necessary irradiation surface, a solid state light emitting element lamp having the same illuminance with a power consumption of a fraction to a fraction of a tenth can be developed. In addition, by installing a reflection mirror for preventing side diffusion inside the bullet-type LED, nearly 20% of the light diffused diagonally forward from the side of the LED element light emitting portion is also irradiated forward and the brightness is increased. .

本発明は固体発光素子の発光部を回転放物面鏡（または円錐状反射鏡）やＶ字型反射鏡の最深部から放光部に向けて配置し、側方から斜め前方にかけての放射光を前方放射させる。また、一般的な砲弾型ＬＥＤのマウントリード（メタルポスト）・メタルステム（インナーリード）等と形称される発光素子部分近傍に拡散防止用に回転放物面鏡（または円錐状反射鏡）を設置し、素子発光部から照射される側方から斜め方向の放射光を全て前方照射させる。 In the present invention, the light emitting part of the solid light emitting element is arranged from the deepest part of the rotary parabolic mirror (or conical reflecting mirror) or the V-shaped reflecting mirror toward the light emitting part, and the emitted light is obliquely forward from the side. Radiate forward. In addition, a rotating parabolic mirror (or conical reflector) is installed near the light-emitting element called the mount lead (metal post), metal stem (inner lead), etc. It installs and irradiates all the emitted light of the diagonal direction from the side irradiated from an element light emission part ahead.
