Title (EN) LED INDICATOR LIGHT
(FR) VOYANT DEL
Abstract: front page image
(EN) An LED indicator light which can realize desired light distribution characteristics and provide a uniform surface emission, and which comprises a plurality of light emitting diodes and a cover lens, wherein a plurality of prisms including a plurality of first prisms are formed on the inner surface of the cover lens, and the plane directions and plane shapes of the incident planes of respective first prisms are so set that first light distribution patterns respectively emitted from first prisms are almost in agreement.
(FR) L'invention concerne un voyant DEL qui peut réaliser les caractéristiques de distribution de lumière voulues et produire une émission de surface uniforme, et qui comporte plusieurs diodes électroluminescentes et une lentille de protection. Une pluralité de prismes comprenant plusieurs premiers prismes est formée sur la surface interne de la lentille de protection, en outre, les directions planes et le formes planes des plans incidents des premiers prismes correspondants sont réglées de façon que les premiers modèles de distribution de lumière émis respectivement à partir des premiers prismes concordent pratiquement.
