A long light emitting apparatus is durable, emits light that can be seen from any direction, and has a low power consumption. The long light emitting apparatus is realized by providing a plurality of LED lamps (light emitting diodes) connected in series at intervals on a connection line. The LED lamp includes an epoxy resin bulb-shaped portion, two leads, and an LED chip connected to the two leads and embedded into the bulb-shaped portion. The surface of the bulb-shaped portion is etched, cut, cut like a diamond, coated with small particles, or covered with an optically-diffusing material so that the emitted light can be diffused and emitted in all directions except backward from the base of the LED lamp. The thus processed surface of the LED lamp can emit light in all directions to be seen from any direction as in the case where filament lamps are used. Since an LED element is used as a light source and the LED lamps are made of resin, the LED lamp is durable Therefore, the long light emitting apparatus can be easily stored and handled, has a low total power consumption, and is an economical apparatus.

L'invention est un appareil luminescent allongé durable qui émet de la lumière visible dans une direction quelconque et qui consomme peu d'énergie. L'appareil de l'invention est constitué d'une pluralité de diodes luminescentes connectées en série à intervalles fixes sur une ligne de connexion. Les diodes luminescentes sont constituées d'une pastille de résine d'époxy, de deux conducteurs et d'une puce connectée à ces conducteurs et enfouie dans la pastille. La surface de la pastille est gravée à l'acide, coupée comme un diamant, revêtue de particules fines ou couverte d'un matériau qui diffuse la lumière de sorte que la lumière émise est projetée dans toutes les directions, sauf vers l'arrière, à partir de la base de la diode luminescente. La surface d'une diode ainsi traitée émet de la lumière dans toutes les directions et peut être vue dans toutes les directions, tout comme une lampe à filament. Les diodes étant utilisées comme sources de lumière et étant faites de résine, l'appareil de l'invention est durable. Celui-ci peut être facilement stocké et manipulé et consomme peu d'énergie, ce qui en fait un appareil économique.
