The traffic lamp can include a controller and a light emitting element When a plurality of light emitting elements is included in the traffic lamp, each light emitting element is coupled with a separate controller. Each controller can be configured to include a predetermined light emitting timing sequence for the corresponding light emitting element. When the power signal is supplied to the traffic lamp, each controller determines a power signal characteristic such as a frequency or a period of the power signal and controls a light output of the light emitting element: based on the power signal characteristic and the light emitting timing sequence. A plurality of light emitting elements can be synchronized using the power signal applied to the traffic lamp."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"LED traffic lamp control system","description":"A traffic lamp and a method of controlling the traffic lamp based on a power signal are provided.
