本発明はテレビジョン受信機等電子機器の発光素子によ
る表示装置に係り、特に同一の表示窓で2色の表示を行
うのに好適な発光素子の取付装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display device using a light emitting element for electronic equipment such as a television receiver, and particularly to a light emitting device suitable for displaying two colors in the same display window. The present invention relates to an element mounting device.
従来の装置は、実開昭62−84943号公報に記載の
ように、発光素子の光が散光部材を介して窓部に照射さ
れる様になっていた。In the conventional device, as described in Japanese Utility Model Application Publication No. 62-84943, light from a light emitting element is irradiated onto a window portion through a light scattering member.
上記従来技術は、散光部材が必要な為構造が複雑になり
、コストアップの要因となっていた。The above-mentioned conventional technology requires a light scattering member, resulting in a complicated structure, which causes an increase in cost.
本発明の目的は、散光部材を削除し、安価に複数の発光
素子による同一表示窓への表示を行うことにある。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the light-diffusing member and inexpensively perform display on the same display window using a plurality of light emitting elements.
上記目的は、表示レンズの入光部を角錐体状に形成し、
上記角錐体部に表示面側にエツチングを施こしたスリッ
トを入れ、発光素子を入光部の各面に対向して配置する
ことにより、達成される。The above purpose is to form the light entrance part of the display lens into a pyramid shape,
This is achieved by providing etched slits in the pyramid section on the display surface side and arranging the light emitting elements to face each surface of the light entrance section.
発光素子の光はレンズの入光部で屈折することにより表
示窓の方へ導かれ、さ゛らにスリットのエツチング面で
散光される為、表示面にむらが生じることがない。The light from the light-emitting element is refracted at the incident part of the lens and guided toward the display window, and is further scattered by the etched surface of the slit, so that no unevenness occurs on the display surface.
第2図に従来の例を示す。プリント基板1に取り付けら
れたLED2.3とキャビネット5の窓部6に取り付け
られたレンズ4の入光部は、散光部材7を介して向き合
う位置に固定されており、LED2または3の光は散光
部材7により散乱することによりレンズ4をむらなく照
らす構造となっている為部品数が多くなるという問題が
あった。FIG. 2 shows a conventional example. The LED 2.3 attached to the printed circuit board 1 and the light entrance part of the lens 4 attached to the window 6 of the cabinet 5 are fixed at opposing positions via a light scattering member 7, and the light from the LED 2 or 3 is diffused. Since the lens 4 is illuminated evenly by being scattered by the member 7, there is a problem in that the number of parts increases.
上記従来技術の問題点を解決するための本発明の一実施
例を第1図を用いて説明する。An embodiment of the present invention for solving the above-mentioned problems of the prior art will be described with reference to FIG.
LED2.3はキャビネット5の窓部6に取り付けられ
たスリット8を有するレンズ4の傾斜をつけた凸形状か
らなる入光部の両傾斜面にそれぞれ対向する位置でプリ
ント基板1に取り付けられている。The LEDs 2.3 are attached to the printed circuit board 1 at positions opposite to both inclined surfaces of the light entrance section, which is a convex inclined lens 4 having a slit 8 attached to the window section 6 of the cabinet 5. .
LED2.3の光はレンズ4の入光部で屈折し窓部6の
中心方向へ導びかれ、スリット8のエツチング面で散光
されるので、散光部材を用いなくとも窓部6の光り方に
むらが生じることはない。The light from the LED 2.3 is refracted at the light incident part of the lens 4, guided toward the center of the window 6, and scattered by the etched surface of the slit 8, so the lighting of the window 6 can be adjusted without using a light scattering member. No unevenness occurs.
本発明によれば、散光部材を削除できるので、コスト低
減の効果がある。According to the present invention, since the light scattering member can be omitted, there is an effect of cost reduction.

A light emitting element mounting device for displaying the operating status of electronic equipment by irradiating light from the light emitting element onto a transparent lens attached to a window provided in a cabinet, the device comprising: In a light emitting element mounting device that uses two LEDs of different colors and displays the status of the device in three ways by turning off at least one of the LEDs,
A light entrance part is formed on the back side of the display surface of the lens, and has a convex shape having two inclined surfaces so that light entering perpendicularly to the display surface from the back side of the display surface is guided toward the center of the display surface by refraction. An etched slit is made on the display surface side in the convex shape of the light input section, and two LEDs of different colors are placed facing each other on the inclined surface of the light input section so that the axial direction of the display surface and the LEDs are perpendicular. The light from the LED is refracted by the inclined surface of the light incident part, guided toward the center of the display surface, and scattered by the etched surface of the slit, so that the display surface is uniformly irradiated.
