Abstract

L'invention concerne un réfrigérateur, comprenant: un compartiment de refroidissement (10) et un ensemble source de lumière de surface en forme de L (12). L'ensemble source de lumière de surface en forme de L (12) comprend un premier corps principal de source de lumière de surface (121) et un second corps principal de source de lumière de surface (122). Une première bande de lumière de DEL est disposée dans le premier corps principal de source de lumière de surface (121), et une seconde bande de lumière à DEL est disposée dans le second corps principal de source de lumière de surface (122). La première bande de lumière à DEL ou la seconde bande de lumière à DEL comprennent une bande de lumière à DEL au moins capable d'émettre une lumière à DEL de deux couleurs différentes ainsi qu'un circuit d'attaque commandant un commutateur de lampe à DEL et une luminosité de couleurs différentes. Le réfrigérateur comprend également un capteur de température. Le circuit d'attaque est configuré pour commander le commutateur de lampe à DEL à différentes couleurs et la luminosité en fonction d'un signal de température renvoyé par le capteur de température. L'ensemble source de lumière à surface incurvée en forme de L utilise une technologie de lumière incidente à deux côtés. La conception de lumière incidente d'un côté produit une lumière mixte de différentes couleurs et de luminosités et la lumière incidente de l'autre côté est une lumière blanche uniquement. La lumière des deux côtés converge au niveau de la surface incurvée de l'ensemble source de lumière de surface en forme de L, remplissant une fonction d'éclairage tout en obtenant également un effet de lumière multicolore.
