Le groupe revendiqué de modèles d'utilité concerne l'électrotechnique, en particulier, la technologie d'éclairage utilisant des diodes électroluminescentes. Cette invention prévient la mise hors tension et la mise sous tension répétées d'une lampe à DEL lorsque le bruit ambiant et/ou l'intensité d'éclairage est proche du seuil acoustique et/ou optique de mise hors tension ou mise sous tension. La lampe comprend une unité à DEL constituée de plusieurs DEL et une unité de commande pourvue d'un moyen de mise sous tension et de mise hors tension des diodes électroluminescentes. L'unité de commande de la lampe, selon un premier mode de réalisation, comprend un capteur acoustique (2), et les moyens de mise sous tension et de mise hors tension des DEL sont conçus de sorte que le seuil acoustique de mise hors tension des DEL soit inférieur au seuil acoustique de mise sous tension des DEL. L'unité de commande de la lampe, selon un deuxième mode de réalisation, comprend un capteur d'intensité lumineuse, et les moyens de mise sous tension et de mise hors tension des diodes électroluminescentes sont conçus de sorte que le seuil optique de mise hors tension des DEL soit inférieur au seuil optique de mise sous tension des DEL. La lampe, selon un troisième mode de réalisation, est une combinaison des lampes des premier et deuxième modes de réalisation.
