Abstract

La présente invention concerne un système d'éclairage de plante à économie d'énergie. Le système d'éclairage de plante à économie d'énergie est principalement caractérisé en ce qu'un circuit d'excitation d'un système d'éclairage de plante est connecté à un circuit d'excitation stroboscopique, puis le circuit d'excitation stroboscopique est connecté à un module électroluminescent. La valeur d'éclairement de base est supposée être K et l'éclairement de base est un éclairement de base requis pour la croissance des plantes. La luminosité électroluminescente du module électroluminescent est augmentée de façon à être N fois (N > 1) la valeur de l'éclairement de base K, la fréquence de pilotage du circuit d'excitation stroboscopique est supérieure ou égale à 2 KHz, et le taux d'épuisement du circuit d'excitation stroboscopique est réglé pour être Y %, Y = 100/N ± 30, et 10 ≤ Y ≤ 90. Ainsi, la quantité de lumière générée instantanément peut être augmentée pour améliorer l'efficacité de photosynthèse des plantes, sans augmenter la consommation d'énergie moyenne globale, de manière à obtenir les effets de réduction de la consommation d'énergie et d'économie d'électricité, et des effets plus pratiques sur la mise en œuvre globale et l'utilisation sont augmentés.
