Patent number: 8869381Abstract: The instant disclosure relates to a low-profile transformer and methods of providing the transformer. The transformer in accordance with the present invention comprises a core unit having a pair of opposingly arranged base portions, an inserting portion, and at least a primary coil and a secondary coil wound around the inserting portion. The top-facing edge of the lateral portions is chamfered to enable tighter fitment into a receiving housing, such as a light tube. The transformer may also include a frame unit having a rounded flange that conforms to the shape of the wound coil. The instant disclosure further provides a method for providing a low-profile transformer that is particularly suitable for adapting in a tubular light device. The physical features and dimension of the transformer may be determined by methods that utilize the analysis of a characteristic equation in accordance with specific operating requirements.Type: GrantFiled: December 30, 2013Date of Patent: October 28, 2014Assignees: Lite-On Electronics (Guangzhou) Limited, Lite-On Technology CorporationInventors: Cheng-Chung Chiang, Yuan-Tan Huang, Wen-Hsiang Wu
