Abstract: The present invention discloses a magnetic component and which includes a bobbin, a magnetic core assembly, a first winding, and a second winding. The bobbin has a main body, a channel, and a pin holder. The main body has a primary winding section and a secondary winding section. The channel penetrates the main body. The pin holder is extended from a side of the main body. The magnetic core assembly is partially disposed in the channel of the bobbin. The first winding and the second winding respectively have two outlet terminals. The first winding is wound around the primary winding section. The second winding is wound around the secondary winding section. Two outlet terminals of the first winding and two outlet terminals of the second winding are configured in the pin holder.

Abstract: A power supply for supplying power to a lamp with functions of dimming, over-current protection, over-voltage protection, arcing protection, and low-temperature start-up is provided. When frequency of the output current exceeds a predetermined value, the power supply is turned off to accomplish a dimming goal and extend lifetime of the lamp. When abnormal statuses such as open-circuited status, short-circuited status, or arcing status occur, a surge current induced by the abnormal statuses may be eliminated to prevent the power supply from being damaged. A high-frequency current detection circuit is configured to detect whether a current supplied to the high-voltage load is a high-frequency current to prevent damage to the electronic elements in the high-voltage load. A current adjusting circuit is configured to adjust an alternating current outputted to a lamp set in response to an environment temperature to supply an adequate alternating current at a low temperature for starting the lamp set.
