Wherein the LED light source module 2 includes a first white LED unit 21 and a second white LED unit 22 adjacently disposed on a substrate; the color temperature adjusting device 3 is connected to the first white LED unit 21 and the second white LED unit 22 through lines provided inside the substrate, respectively, for adjusting the color temperature of the LED light source module 2. The first white LED unit 21 may be a relatively high color temperature white LED (for example, 3850K to 6500K, K is an acronym of color temperature unit Kelvin), and the second white LED unit 22 may be a relatively low color temperature white LED (for example, 2700K to 3850K). The first white LED unit 21 and the second white LED unit 22 may further include one or more white LEDs, respectively. The color temperature adjusting device 3 may control the current passing through the first white LED unit 21 and the second white LED unit 22, respectively, and may change the color temperature of the LED light source module 2 by a difference in color temperature CCT value between the first white LED unit 21 and the second white LED unit 22, and by a change in current ratio of the two.
