Lorsque le corps de lampe est dans un état de mise hors tension, l'ensemble de commande commande le système de blocage de lumière de sorte qu'il assure un blocage de lumière. Le système de blocage de lumière assure un blocage de lumière intelligent en fonction des conditions d'éclairage du soleil. De multiples modes de blocage de lumière sont prévus, et les modes peuvent être configurés séparément ou d'une manière combinée, ce qui permet d'obtenir un meilleur blocage de lumière ciblé. Un capteur de gravité (3) détecte une position de montage de la lampe de scène.

C'est-à-dire, la direction du support de lampe (1) de la lampe de scène est réglée pour être aussi proche que possible de la direction de gravité, empêchant ainsi la lumière du soleil d'entrer dans une lentille du support de lampe. L'appareil de protection contre le blocage de lumière présente une reconnaissance automatique avancée, une intégration de système flexible et est rentable et facile à mettre en œuvre.
