Definitions

  • the utility model relates to the field of road illumination, in particular to an LED street lamp which automatically senses and adjusts brightness.
  • LEDs are characterized by energy saving, environmental protection, long life and small size, they are often used in street lighting.
  • the traditional street lamps are timed. When the light is strong, turning on the lights wastes a lot of electric energy. When it is raining, the street lights are not turned on and the street lights are not activated.
  • One solution is to set the street light as a photosensitive LED street light. However, when the existing photosensitive LED street light detects that the surrounding brightness is low, the street light switch is directly turned on, and the automatic adjustment cannot be performed. In addition, the light sense measurement is inaccurate. It will also waste the corresponding resources.

Abstract

Réverbère à DEL automatiquement photosensible et réglable en luminosité comprenant une alimentation, un module de collecte de signaux, un capteur de signaux, un dispositif de commande centralisé et des sources de lumière à DEL (1, 2, 3). Le dispositif de commande centralisé comprend un comparateur de signaux, une puce de commande et trois dispositifs de commande de commutation. Le module de collecte de signaux comprend de deux à trois collecteurs de signaux de lumière. Une extrémité de sortie du module de collecte de signaux est séquentiellement connectée à la puce de commande à l'aide du capteur de signaux et du comparateur de signaux. La puce de commande comprend un relais, un module d'entraînement et un transformateur. Le transformateur est connecté à l'alimentation. Une extrémité d'entrée du relais est connectée au comparateur de signaux. Le transformateur et une extrémité de sortie du relais sont connectés à une extrémité d'entrée du module d'entraînement séparément. Une extrémité de sortie du module d'entraînement est connectée aux trois dispositifs de commande de commutation séparément. Les trois dispositifs de commande de commutation sont connectés aux trois sources de lumière à DEL respectivement. La luminosité du réverbère peut être modifiée en fonction d'une situation spécifique, la précision de collecte de signaux est élevée, la luminosité lumineuse est uniforme et le réverbère est de faible coût, sûr, fiable et a une longue durée de vie.
