Publication number: 20260009509Abstract: A lighting apparatus includes a bulb shell, a bulb cap, a light source structure and a plurality of color LED modules. The bulb cap encloses a driver configured to convert an external power source into a driving current. The light source structure is disposed within the bulb shell. The light source structure includes multiple elongated light source plates arranged side by side to form a folded polygonal tubular shape. Each of the light source plates extends in a longitudinal direction. Multi-color LED modules are disposed on each light source plate and arranged along the longitudinal direction. At a given longitudinal position, at least two LED modules respectively located on two adjacent light source plates have different colors.Type: ApplicationFiled: July 3, 2025Publication date: January 8, 2026Inventors: Huiwu Chen, Luyan Zhou, Wenhao Lin, Hongkui Jiang, Tangzhong Liu

Patent number: 12442497Abstract: A lighting device includes a flexible substrate, four types of LED modules, and a driver. The substrate has an elongated area divided into four bands along the Y-axis. First-type LEDs are placed on the first band in a row along the X-axis, parallel to the substrate's length. Second-, third-, and fourth-type LEDs are placed on the second, third, and fourth bands, respectively. Each type emits light with different optical properties. The Y-axis is perpendicular to the X-axis, with first-type LEDs aligned with fourth-type LEDs and second-type LEDs aligned with third-type LEDs. First-type LEDs are offset from second-type LEDs along the X-axis. The driver converts external power into four currents, adjusting their relative ratios to control the combined optical output.Type: GrantFiled: March 4, 2025Date of Patent: October 14, 2025Assignee: LEEDARSON LIGHTING CO., LTD.Inventors: Huiwu Chen, Zongyuan Liu, Xiaobo Chen, Yongshu Zheng, Cheng Luo
