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.
